     АНГЛИЙСКИЙ ДЛЯ РУССКОЯЗЫЧНЫХ ЗОЛОТОДОБЫТЧИКОВ. ENGLISH FOR RUSSIAN SPEAKING GOLD MINERS
    .
      Gold mining has a storied and often checkered history of rushes, booms, contraband and conflict  
      У золотодобычи есть легендарная и часто изменчивая история лихорадок, бума, контрабанды и конфликтов
    .  
       Gold In nature.
     In nature, gold occurs, usually in the native form. Often it contains impurities of silver, copper and bismuth.
    Silver content sometimes up to several tens of percent. Depending on the impurities gold is light yellow, reddish, greenish.
    Natural gold can be finely divided, the size of its particles do not exceed 0,005 mm, pulverized - particle size 0.005-0.05 mm fine - 0,005-2 mm and large,
    that is, more than 2 mm. There are two main types of gold deposits: Indigenous and alluvial (placer).
    Primary deposits are usually formed from hot underground water heated by magmatic centers.
    They (the fields) are in the form of various milk-white quartz veins occurring in granite, marble, limestone, sandstone and other rocks.
     A placer deposit or is an accumulation of valuable minerals formed by gravity separation during sedimentary processes.
    Types of placer deposits include: eluvium, alluvium, beach placers, and paleoplasers.
    A gold nugget is a naturally occurring piece of nativ gold Watercourses often concentrate nuggets and finer gold
     Nuggets are also found in the tailings piles of previous mining operations, especially those left by gold mining dredges.
    Nuggets are gold fragments weathered out of an original lode.
    They often show signs of abrasive polishing by stream action, and sometimes still contain Nuggets are usually 20K to 22K purity (83% to 92%).inclusions of quartz or other lode matrix material

    Fraud - обман; мошенничество, жульничество; подделка
    First, Fraud
    Buying scrap gold (old jewellery) for only half or less of the gold price can be considered as fraud.
    Another way of fraud is selling gold numismatic coins at prices which highly surpass the material and collector"s value. The victims are often old people who can easily be tricked into this business deal.
    Second, Misrepresentation
    Imagine, a bank sells gold which the buyer never physically receives, but which is stored in the bank"s vault.
    The bank further charges the gold owner storage fees. So fine so good. Let"s now assume the owner of the precious metal insists on seeing the gold.
    Now it is discovered that the bank never actually possessed the gold. How would one call the bank that asked for storage fees of something it never stored?
    Third, Market Manipulation
    The last gold scam is market manipulation as this action tries to distort the market equilibrium.
    .
    Мошенничество первое
    Золотоскупка старых драгоценных изделий за половинную или меньшую стоимость золотого содержания можно рассмотреть как мошенничество.
    Другой способ мошенничества - продажа золотых нумизматических монет по ценам, чрезвычайно завышенным от истинной стоимости материала коллекционера.
    Жертвами, зачастую могут стать - старики, которых легко обмануть в этой коммерческой сделке.
    .
    Заблуждение второе
    Представьте банк, который продает золото покупателю, которое физически не существует, но якобы находиться в хранилище банка. Банк взыскивает сборы за хранение золота владельца.
    Это настолько хорошо, насколько прекрасно.
    Давайте теперь представим, что владелец драгоценного металла настаивает на том, чтобы посмотреть на своё золото.
    Тогда обнаруживается, что банк никогда фактически не имел это золото.
    Как можно было бы назвать банк, который взыскивал сборы за хранение того, что он никогда не хранил?
    .
    Третье: махинации рынка
    Последнее золотое жульничество - махинационные действия рынка, искажающие равновесие рынка.
      The History of Gold Mining--- Первобытные золотоискатели [Аброл Кахаров]
    .
      It is impossible to know the exact date that humans first began to mine gold, but some of the oldest known gold artifacts were found in the Varna Necropolic in Bulgaria.
      The graves of the necropolis were built between 4700 and 4200 BC, indicating that gold mining could be at least 7000 years old.
    Gold has a widespread occurrence in practically every country of the world and has influenced the exploration and settlement of most.
    In Africa, Europe, and Asia ancient gold mines are known in Egypt, Spain, France, Great Britain, Yugoslavia, Romania, Greece, Turkey, Saudi Arabia, Iran, India, China, Japan, and the USSR.
    Ancient placers have yielded gold from the rivers Tagus, Guadalquivir, Tiber, Po, Rhone, Rhine, Hebrus (Maritsa), Nile, Zambezi, Niger, Senegal, Pactolus (in ancient Lydia),

      Gold occurs in many geologic settings of which three are the most important.
      "Epithermal" gold deposits are basically hydrothermal veins associated with
      subduction zone volcanoes.
      The epithermal means that the gold-bearing veins were emplaced at shallow depths (less than a few km underground) and have been exposed by erosion.
      As the name implies, "mesothermal" gold deposits were emplaced at greater
      depths and thus deeper erosion is needed to expose them.
      The deposits are associated with "granite-greenstone belts".
      Unlike these two kinds of quartz vein deposits, the third common kind of gold
      deposit is sedimentary.
      "Placer" deposits consist of particulate gold laid down in stream and beach sands.
      The gold comes initially from vein deposits that then follow the rock cycle(weathering, erosion, transportation, deposition).
    Mining investors face the challenge of deciding which company to invest in based on their multiple international projects because of the varying nature of reporting standards worldwide.
    With the current boom in the mining industry, companies tend to prepare reports for investors, based on the eventual stock exchange for which they want the listing.

      While Mineral Resources can be estimated based on predominantly geoscientific information, Mineral Reserves are dependent on the consideration of modifying factors such as mining,
    metallurgical, economic, marketing, legal, environmental, social, and governmental factors.
    Such Mineral Reserve estimation will, therefore, require the knowledge of a variety of disciplines.
    Mineral Reserves can only be estimated based on Indicated or Measured Resources. In Figure 1, the double-headed arrows indicate that resources can be converted into reserves, and vice versa, between the categories shown.
    The dashed line between Measured Mineral Resources and Probable Mineral Reserves indicates that this conversion is possible in situations where the collective effect of the modifying factors
    provide uncertainties which would not permit the Measured Mineral Resources to be converted into Proved Mineral Reserves.
    It does not indicate a reduction of geological confidence. It follows, also, that an Indicated Mineral Resource could never be converted directly (ie. without first being upgraded to Measured Mineral Resources)
    to a Proved Mineral Reserve since there would not be the requisite level of geological confidence.
      The Competent Person must choose, and is the only person permitted to choose, the appropriate classification category.
    Depending on the reporting jurisdiction, there will be different reporting requirements and the Competent Person must be aware of these existing differences.
    While these differences may not always be material differences, they are important for proper reporting in the various jurisdictions.

      Mining process Open-pit mining is a kind of surface mining. Mining companies choose this way to get rocks and minerals out of the ground because it is the easiest and cheapest way to do it.
    Open-pit mining is only used if the rocks or minerals are close to the surface of the land or if a normal tunnel-type of mine isn'tpossible.
    Hard rock mining is a kind of underground mining. With this kind, an opening is made that is called an adit.
    .
    Система вскрытия [А. Кахаров]
    .
      Tunnels into the ground are dug, blasted with dynamite, or drilled out. These tunnels are called shafts.
    Shafts are dug straight down [vertically] into the ground. One shaft might be for miners to use to go in and out of the mine.
    Another shaft is used for air or ventilation. Drift mines are a form of underground mining.
    This kind of mining is done when the rock or mineral is on the side of a mountain.
    This makes it an easy, cheaper way to mine.Whenever possible, the opening to the mine will be dug a little lower than the rock or mineral vein.
    This makes it easier to get the materials out because gravity helps move them downhill. The tunnels that are dug are horizontal and are called drifts.
    Shaft mining is the deepest form of underground mining. Underground mining is chosen when the rock or mineral is too far to reach using surfase mining.
    Shaft mining is the kind of mine that you usually see in movies where the miner travels straight down into a deep, dark tunnel (shaft) until he reaches the bottom.
      The shaft mine has a vertical manshaft, a tunnel where the men travel up and down in an elevator. Slope mines are another kind of underground mine.
    .
    Система разработки [А. Кахаров]
    .
    With slope mines, the gold or minerals are far enough under ground that surface mining can"t reach it. It is called a slope mine because the shafts are slanted. This kind of mining is done when there would be problems drilling shafts straight down. Slope mines are not usually too deep.
    .
      Extraction of gold
    .
      Gravity Concentration Methods A common method of extracting gold from ore requires crushing the rock and then sifting it through sluices, jigs, spirals and tables. The crushed rock may be soaked with water, and the rock and gold then sent through a series of shakers and sifters. Gold is heavier than most materials and gets trapped in the bottom of these sifters. This is the lowest cost method of obtaining the gold, but may leave a fair portion of gold in the rocks themselves.
      Flotation Process
      Crushed gold ore has a high concentration of sulfides. Miners will make a slurry of the crushed ore, add oil and mix with air bubbles. Sulfides do not become wet easily and so float to the surface for skimming along with the gold. The type of oil depends on the type of sulfides then processed so the gold precipitates out of the solution in a large, shallow tank.
    .
    Heap Cyanide Process
    .
      A less efficient way of extracting ore than the cyanide mill is the heap cyanide leaching process. The gold ore is placed on a liner and the cyanide solution is sprinkled on the gold ore. The gold leaches through the ore and is channeled to a man-made pond for holding and precipitation.
      Bioleaching extraction This process involves the oxidation of sulfide, ferrous, and sometimes carbon containing minerals in order to liberate the gold trapped within.
      Recovery gold from ores or concentrat through the use of livng organizms. This is much cleaner than the traditional heap liaching using cyanide. Bioleaching is one of several applications within biohydrometallurgy and several methods are used to recover
      Cu, Au, Zn, Pb, As, Sn, Ni, Mo, Ag, and Co.
      Pyrite leaching (FeS2): In the first step, disulfide is spontaneously oxidized to thiosulfate by ferric iron (Fe3+), which in turn is reduced to give ferrous iron (Fe2+):
      The net products of the reaction are soluble ferrous sulfate and sulfuric acid. The process for copper is very similar, Chalcopyrite leaching.

      Advantages the dry enrichment technology for gold mining industry: Ecologically clean and safe (without using of water and chemicals);
    All the dry complex of machines and equipment occupies small working space. So, it can be placed directly in the bowels (quarries, mines);
    The dry complex can be easily moved from one place to another;It considerably reducing transportation costs for the mining industry by enriching the "tails" (wastes) at the place of their "production";

      Gold smeltingAmalgamation [Abrol Kakharov]
    .
    Metallurgical process used to separate metal from ore, rocks that contain gold.
    The ore is ground and treated with chemicals to remove some impurities before being heated at high temperatures with a flux that triggers a chemical reaction, causing the metal to precipitate out of the mixture.
    After gold has been smelted, it needs to be refined to purify it so it can be used in production of a variety of products, from jewelry to electronic components.
    Sustainable development Strategies for sustainable development of the small-scale gold mining industry.
    In a typical small-scale gold mining operation where rock is mined, the ore is excavated manually and reduction is carried out using a combination of jaw and rocker crushers, hammer, disc and stamp mills.
    The stamp mills and rockers are manually while the others are powered by diesel or electricity.
    Production of gold by the small-scale sector has led to significant socioeconomy impact on individuals and communities involved in the small-scale mining activity
    and an increase in the overall production of the minerals in the country leading to increased foreign exchange earnings.
    The increase in mineral production has been at a cost to the environment and some communities have had an adverse environmental impact.
    Tailings of Gold Mining are the materials left over after the process of separating the valuable fraction from the uneconomic fraction.
    The extraction of minerals from ore can be done two ways: placer mining, which uses water and gravity to extract the valuable minerals, or hard rock mining, which uses pulverization of rock, then chemicals.
    In the latter, the extraction of minerals from ore requires that the ore be ground into fine particles, so tailings are typically small and range from the size of a grain of sand to a few micrometres.
    Mine tailings are usually produced from the mill in slurry form (a mixture of fine mineral particles.

    Cyanidation process Cyanide Mill Process. A very efficient method of gold extraction is dissolving the crushed gold ore in a weak cyanide solution.
    Gold dissolves in cyanide in special tanks, where the solution is mixed and aerated. The cyanide solution is

    .
    The cyanide leaching process, introduced to the gold-mining industry about 120 years ago, was at the forefront of the technological revolution in the industry.
    The cyanidation process, which was cheap and very efficient, allowed ever lower-grade ores to be processed economically, even in the era of gold price fixing at the US$35/oz standard.
    .
    . CURRENT TREATMENT Today, in most mining jurisdictions around the world, cyanidation plant tailings must be treated with chemical oxidants on the site of the metallurgical operations, and cyanide
    (as well as most metals) has to be removed from solution to very low levels, before deposition in tailings dams or any other such storage facilities.
    The best alternative is to recover cyanide from the tailings and recycle it to leaching.

      WHAT IS AN ABANDONED MINE?
    .
      The Mining Act has used the term "abandoned" to describe sites where the proponent has ceased or suspended indefinitely advanced exploration, mining, or mine production on the site, without rehabilitating the site.
    Other terms commonly used in the mining industry include: inactive mine, orphaned mine, and unattended mine. The term "orphaned" mine has been used by some to describe sites without an owner.
    Sites described as "temporarily shut down" or "under care and maintenance" would imply that an owner is still actively managing the site.
    In choosing a definition, the important point is the need to focus on public safety and environment problems, not on who owns the site.
    The term "abandoned" mine, as defined above, seems to best serve this purpose of this report.

    The prefeasibility report on development "VENUS MINE"Photo Venus mine [Интернет]
    .
      Gold and silver mining Venus Mine have been popular in the area on Tagish Lake since 1905.
    The Venus mine and tailings pond are located approximately 22 kilometres south of Carcross on the South Klondike Highway in Yukon.
    The tailings from the Venus Mine are located below the mine site, some distance from the mill.
    There are many minerals still in the tailings, arsenic being of greatest concern. Arsenic levels in the water and vegetation continue to be measured on a regular basis.
    The good news is the reclamation solution is working! Arsenic tested in the surrounding vegetation has been reduced to trace amounts. In two years, the arsenic levels have been reduced by 150 times.
      1.Introduction The given feasibility report is executed by the professor Abrol Kaharov under the task coordinated with the owner of deposit Ron Berdahl, during the period of August 15, 2004 -January 15, 2005.
      2.The purpose of research consists in definition of economic efficiency of an opportunity of gold deposit "Venus Mine" development in view of technical requirements of mineral resources development in defined conditions and a modern economic situation in the market of base metals and gold in the world.As a basis of the analysis and evaluations have been accepted the reserve calculations carried out in 1967-1985 and submitted by the prospecting organization.
      3.During the work the geological information, reporting data of Mining Recorder's Office (Mayo, Whitehorse, Yukon Territory) were used as official materials. Authors express the gratitude and thank the Chief Geologist of the Yukon Government Mike Burke and Ron Berdahl for the help during studying of the data of the deposit and others in Territory Yukon, and also for valuable advice during the compiling of the feasibility report.
    History of mining on gold deposit "Venus Mine" Yukon Territory. The end of 19th century and the beginning of 20th century have been marked by the gold fever in Yukon after discovery of rich placer gold deposits by gold diggers in Klondike and Bonanza rivers near small town of Dawson City. As well known since 1898 the registered gold miners had been carrying out prospecting and extraction of gold from 239 gold-bearing rivers and streams. During this period called "Gold Fever" alongside with known Yukon placer gold deposits, many deposits of nonferrous metals and gold began to be involved in prospecting and mining. At the same time, the north end of the Venus Vein system was staked in Sep/01 by J.M. Pooley, A.B. Palmer & J.M. Stewart as Venus, Uranus, etc. (3768) and was transferred in 1905 to Conrad Cons ML, which explored with at least 914 m of drifting from four adits and three shafts and constructed a 460 m aerial tramway and a 91 tone mill, at a total cost of over $750 000 between 1905-12. The claims were taken to lease in 1912 by Yukon District Gold Mg CL. About 1830 tones were mined, mostly from the Venus 2 claim, but only a small portion was milled due to poor recoveries. The remainder was hand sorted and shipped directly to smelters at Ladysmith and Tacoma. Lessees, mainly Lackinaw and Tagish ML in 1916 and Can Harper Mg Corp Land Montana-Yukon Mg CL in 1920, shipped 1556 tones of high grade ore worth $120 000 and 03 tones of concentrate worth $26 000, according to report. Brown estimated in 1963 that 2450 tones averaging 21.9 g/t Au and 2338.2 g/t Ag were shipped between 1910 and 1920. The south end of the main Venus vein, plus the Red Deer and Humper veins, were mostly staked in 1904-06 and were known as the Dail-Fleming group. These were optioned by the Anglo-American Cons C from 1906-08, by Conrad Cons ML briefly in 1908, and by Caribou Mg CL in 1917. They were explored with at least five adits and three shafts. In 1922, Maybell MC put in a 975 m adit on the Maybelle fraction adjoining the Venus Mine. In 1928, Yukon Gold Co acquired the Venus Extension, the Ray cl (19024) and Peggy cl (19023) but did little work. Except for examination by Treadwell Yukon ML in1919, Hollinger in 1922, Yukon Gold ML in 1929, Transcontinental Res L in 1946-47 and Giant Yellowknife in 1963, the property was idle until 1966. Between 1940 and 1960, the property was consolidated by the Tagish Lake Synd, which sold it in 1966 to Venus ML. Venus built a road from Carcross, completed 2059 m of drifting, 387.7 m of raising and 2191.8 m of u.g. drilling from two adit levels (2700 ft and 2600ft). Production commenced in Sep/70 and by Jun/71, when the mine was closed because of poor recoveries (68% Au, 79% Ag, 84% Pb & 73% Zn) and heavy losses, the mill had treated 58 900 tonnes grading 5.8 g/t Au, 181.7 g/t Ag, 3.7% Pb and 2.5% Zn. The Tagish Lake Synd property was optioned in 1979 by United Keno Hill ML, which added GHI in April, resampled the underground workings, drove 295 m of crosscuts off the 2600 Level and drilled 27 holes (1378 m) below the level later in the year. Between Oct/80 and Oct/81, about $9 million was spent on construction of a new 91 tonne/day mill, 10 km south of the adit, but production was deferred because of low metal prices. Exploration in 1984 consisted of 324 m of drifting, plus two raises (193 m) on the 2850 Level and 108.5 m of sublevel drifting from the raises. In addition, 9 diamond drill holes (1430 m) and 31 rotary holes (2819 m) explored the Venus and Uranus Vein systems on surface . Modern fringe staking includes Mars to the north in Sep/64 by Peso Silver ML; Gold in Mar/74 by D. Waugh; Columbia in May/75 by B. Fitch; Red in Jul/77 by R. Piercy; & Rainbow & Sandpiper to the north in Aug/87 byJ.B. O'Neill & R. Hilker. A feasibility study on remediation of the mine tailings was planned in summer 1994 under the Federal Arctic Environmental Strategy. In the summer of 1995 the tailings were partially dug up and then sealed in a clay liner. In Aug/95 Raindrop were tansferred in trust to the Carcross First Nation as partial settlement of their land claim. In Jul/97 J. O'Neilstaked Venus fraction adjacent to the occurrence. In Sep/97 B.Scott staked Au 2.5 km to the north.
      
    3.Geology of deposit "Venus Mine" Most of the development has been on the main Venus vein, a north-trending, shallowly westdipping, quartz fissure vein system which cuts intermediate volcanic rocks of Cretaceous age.
    The vein has been traced for more than 1.6 km on surface along a steep mountainside overlooking Tagish Lake.
    Fourteen other veins are present but most have not been explored. The 2700 adit is located 760 m southwest of the original mine on the Venus #2 claim, while the 2600 adit is 365 m northeast of the 2700 adit.
    The Red Deer vein is located farther uphill to the west, and strikes more northeasterly, whereas the Humper Vein is situated at the south end and strikes easterly.
    The Venus vein, which is the strongest structure on the property, ranges from about 8 cm to 2.4 m wide (average 0.9 m) and is surrounded by an alteration envelope up to 3 m wide.
    Mineralization consists of coarsely crystalline quartz and carbonate carrying irregular bands and pods of pyrite, arsenopyrite, galena and sphalerite with minor tetrahedrite and chalcopyrite.
    Mineralization on the other two veins was reportedly similar in composition but narrower and less abundant.
    In the mine, two types of faults cut the vein: weak normal and reverse faults that strike normal to the vein, and strong faults that trend almost parallel and cause the vein to roll, pinch and swell.
    Most mineralization is concentrated in swells associated with the strong faults.
    Twelve ore shoots ranging in length from 14 to 42 m were sampled by Venus ML and gave an average grade of 13.4 g/t Au, 396.0 g/t Ag, 2.6% Pb, 1.7% Zn & 0.09% Cd across a minimum width of 1.2 m.
    At the start of production, ore reserves were calculated at 68 466 tonnes proven and 53 865 tonnes probable.
    After the mine closed, remaining reserves were recalculated as 54 364 tonnes proven and 16 017 tonnes probable averaging 9.26 g/t Au, 247 g/t Ag, 2.1% Pb and 1.4% Zn across a 1.5 m mining width.
    Operational problems were blamed on insufficient cutting of high assays, dilution caused by the flat dip, and poor gold recoveries from arsenopyrite because the cyanide circuit never reached full operation.
    Resampling and further exploration drifting and drilling by United Keno Hill Mines Ltd extended mineralization to 170 m below the 2 600 level and led to the calculation of new reserve figures in Jun/80.
    These figures indicated proven reserves of 54 354 tonnes, probable reserves of 16 017 tonnes and indicated reserves of 38 329 tonnes, grading 7.55 g/t Au, 226.3 g/t Ag, 1.89% Pb and 1.37% Zn.
    The 1984 work on the Venus Vein increased proven reserves to 61 689 tonnes grading 10.98 g/t Au, 305.14 g/t Ag, 2.5% Pb and 1.5% Zn.
    These figures do notinclude 12 156 tonnes of ore grading 5.83 g/t Au, 147.43 g/t Ag, 1.3% Pb and 0.7% Zn stockpiled at the Venus mill site.
    The 1984 drilling on the Uranus Vein outlined a zone 50 m long averaging 3.8 g/t Au, 870.8 g/t Ag, 5.7% Pb and 2.6% Zn across 1.5 m.
    Gold occurs with galena primarily as fracture fillings in arsenopyrite. Steeply dipping ore shoots, which are not visually apparent, comprise 20% of the veins and typically contain both types of mineralization.
    The wallrocks are altered to a sericitecarbonate-quartz-pyrite assemblage with local pods of intense clay alteration.
    A rare hydrous arsenite of iron and calcium was identified here in 1913 by Tyrrell Graham and named Yukonite.

    5The average grade of zinc in ore - 0.7 %
    .
      Without going in details of the analysis of practice and Feasibility Study of Venus Mine in the past, it is necessary to note that estimated economic parameters of the project efficiency appeared today
    unsuitable because of noticeable change of world market prices of gold and base metals, and also practice of primary development of the deposit,
    revealed high degrading of ores during excavation and low recovery of gold with high losses into tailings during processing.
    Also were problematic qualitative-quantity properties of arsenic in ore and concentrates. These and other production-economics indices of work practice were the reason for a cessation of work on this mine.
    In the given work when compiling the production-economics project are considered: reliability of the grade of gold in the calculated blocks, actual volumes of degraded ores, applications of new methods
    of enrichment and extraction of gold and other associated components, and also that is especially important provides measures for the guarantee of an environment safety from arsenic and other hazard impurities.
    In connection with complication of processing technology and the raised necessity of preservation measures of the environment authors of the project have made recalculation of ore reserves of the deposit
    with clearly defined changes toward increases of standards of the grade of gold and thickness of the ore body.

    4. Factors of risk and measure of the guarantee of profitable work of the enterprise. Analysis shows that the factors of risk can be:
    .
    a) High degrading of ore during the excavation and the low recovery of the basic and associated components during the processing. As the protection measures the necessary volume of the ground and underground prospecting works is planned, allowing a transfer of the existing reserves into the higher category.
    .
    b) The offered technology of ore processing, obtaining the integrated concentrates and KNOW-HOW will allow to reach the higher results of recovery at the processing plant (smelter) with the sufficiently high concentration of metals in the concentrat. c)Entry of the increased content of arsenic into the technology of excavation and processing is possible. The bio-hydro-metallurgical method of concentrates processing is planned at the factory. d) The situations, connected with the natural disasters and other circumstances, for which the development and the mine production must be insured properly in accordance with established procedure.

      The Pre-feasibility report development "Thompson mine" Thomson mine [Интернет]
    Geographic and economic situation. The abandoned gold mining "Thompson - Landmark" is located near the eponymous lake, 48 km northeast of Yellowknife, the Northwest Territories of Canada.
    The history of the study and development. Discovered in 1938. In the 1940s, uncovered the underground mine workings to a depth of ~ 300 m. Passed two operating mines, an exploratory shaft (hole) depth of 50 m, bored ~ 1,000 m exploratory holes . Additional research in 1978 - 1987's., ~ 3000 m were drilled exploratory holes, selected by the gross mass of 6 tons technology test sample
    .
    GEOLOGICAL The ore field is composed of cordierite and quartz-mica shale formations "Burwash" Archean. The structure of the ore field is determined by tight folds and joints which have spread 320 - 330 º. Available data are interpreted by previous researchers as the presence of an overturned anticline, castle of which plunges gently to the southeast. All of the known ore bodies are controlled by disjunctive structures ("shear zones"), sub-parallel axial planes of these folds. To date, 11 known ore bodies, of which at least 5 have a significant length - from 50 to 300 m. The ore body "Kim" traced for 800 m along strike. The ore bodies are quartz vein zone, less common veins ranging from a few centimeters to 3 m. The composition of the veins: quartz, tourmaline, pyrite, arsenopyrite, chalcopyrite, pyrrhotite, sphalerite, galena. The total content of sulfides to 2%. Marked accumulation of galena, where its content reaches few percent. Gold in ores free, of various sizes. In the area of ceiling "Trail" marked nuggets weighing up to 1.5 g and up to 1 cm. Produced 133 989 tones of ore with an average gold content of 16.3 g / t. 13. RESERVE 1.3 Retrieved 2188 kg of gold and 428 kg of silver. Gold resources in the category "Indicated" are 461 kg s / c = 6.36 g / t. Gold resources in the category "Inferred" up to 1095 kg / s = 9.33 g / t. All these resources are concentrated in areas "Kim" and "Fraser". According to information published in 1988 by "Ardic Exploration", on the results of its drilling within the zone "Kim" revealed two new ore column, increase resources amounted to 1.7 tons of gold at an average grade of 9.3 g / t. 14.
    FUTURE FACILITY The above resources "Indicated" concentrated mainly in the ceiling areas of pillars "Kim" and "Fraser", resources category "Inferred" - within the zones "Kim" and "Trail".
    The results of operations of the company "Ardic Exploration" demonstrate the possibility of a substantial increase in resources during a large scale how exploration by tracing the known ore bodies along strike and at depth.
    The object is characterized by favorable geographic and economic situation, its proximity to Yellowknife with developed infrastructure.
    The structure of the ore field and the presence of numerous ore bodies and mineralization of the high points (a few tens of g/t) and concentrations of numerous occurrences of visible gold
    indicate a high probability of identifying new small reserves of ore (up to 100 000 tones), but the rich (10-20 g / t) ore bodies.
    The most promising sites are interlocking parts of anticlines, folds and bends of hinge zone of intersection of their faults. In these areas may identify "blind" ore bodies.
    It"s necessary to conduct evaluation activities within the zones Arsenic, Croesus, B-vein and Lahti, and further exploration within the zones Fraser, Kim (deep levels) and the Trail.
    Substantial potential for growthstocks is to apply the methods of testing and processing of samples.
    large gold ore. They include: drilling of a dense network (in the areas of detail - 25 × 25 m) for the localization of ore columns, drilling of exploratory wells of larger diameter (HQ), selection of trench samples weighing 10 - 15 kg,
    trench selection of samples, sample processing scheme with preliminary extraction of a large gold (screen analysis, or washing in a centrifugal concentrator).
    All of the known ore bodies can be partially worked out from the surface to a depth 10 m.
    Project considers involves conducting fully automated sewage extraction using self-propelled equipment (drilling carriages and Scooptrams on sites with a capacity of ore bodies greater than 3.0 m
    and maintaining sewage treatment semi-mechanics excavation using hand-held telescope and drills and LHDs in areas with lower power of the ore bodies .
    Transport across a broken ore and waste rock backfill material is self-propelled wheel with diesel equipment.
    The use of tailings as a bookmark out space leads to a smaller negative impact on the environment and the significant reduction of disturbed lands.
    Thus, the condition will be reduced maintenance, increased volume of the ore mass, and therefore stocks.
    According to available information, ore is easy to enrichable, gold is free, large, low sulphide content. One might expect that the extraction of the gravitational enrichment is not less than 90%.
    Currently, gold-field "Thomson - Lundmark" should be considered as a promising subject for exploration.
    A relatively small amount of work carried out within 1-2 years, can yield growth stocks in 2 - 5 tons of gold at an average grade of the ores of 10-15g

    The overall performance of the surface mining area - 15 000 t / year. project adopted a year-round operation. Number of shifts per day - 2, operating hours - 12 hours.
    .
    MINING PARAMETERS
     Underground Mining Site For mining purpose it will be provides underground mining layer method or sublevel caving. It is envisaged sinking spiral ways to maximum depths of processing and the subsequent opening of the ore bodies field drifts. Given the relatively small length of the ore body, expected mining of each ore body by a spiral way, providing, by safety, the possibility of staff at the surface is produced by running two penetrations of the rising mines.
      16.4.2.The total number of spiral ways are in the number of ore bodies - 2; ride rising 4. The total volume of mining-capital work - 17 000 m3 / 45 000 t.
    Operating losses during extraction will consist of ore losses in the array at the contacts with the host rocks and ore losses from occurring at its loading and transport.
    Dilution will occur as a result of host rock stuck in breaking the ore on account of low capacity of the ore bodies.
    Geometrical parameters are defined mines adopted the scheme of processing and mining equipment and parameters given in the table.
      For mining and tunneling of capital developments and mining complex will be used by small equipment manufacturing company "Sandvik Mining and Construction", designed to work in tight spaces at small size mining ore bodies.
    Blast hole - portable punches, loading and delivery of mining and ore mass - Scooptrams SANDVIK LH201; transport ore to the surface - dump SANDVIK TH315.
    To meet the challenges of underground mining intended to be used in underground mine rig SANDVIK DE110, and from the surface - SANDVIK DE140.
    The general scheme of works for the underground mining area is as follows:
    .
    1. Manufacturing Mining and capital works (spiral revolt, the approach crosscut).
    2. Drifting sublevel drifts.
    3. Drilling holes fenders.
    4. Breaking ore.
    5. Loading of ore in the dump.
    6. Hauling ore to the lodge on the surface.
    7. Delivery of backfill material.
    8. Bookmark gob mines.
    Average parameters of the operating unit based on the adopted technology as follows:-Length - up to 100 m - The vertical height - 25 m - Height substages - 12.5 m - Average power of the ore body, - 1.2 m - Height excavation of 1.5
    Cutter capacity is determined by the minimum width of LHD equipment.
    Dilution in this case is 40%. Specific volume set-threaded workings for 1000 tons of ore - 70 m.
    The average ore reserve within one bloc- 20 000t of ore mass length delivery on the roadway LHD 100-150 m.
    The surface area Provides for open pit surface areas to a depth of pits 20 m. Mining of the ore bodies - by split trenches. The total volume of mining-capital work - 30 000 m3.
    Operating losses during extraction will consist of ore losses in the array at the contacts with the host rocks and ore losses from occurring at its loading and transport.
    Dilution will occur as a result of host rock stuck in breaking the ore on account of low capacity of the ore bodies.
    Blast hole drilling - compact self-propelled drilling rig Sandvik DX500;
    excavation of rock chipped from the face bulldozer CAT D6, loading by a front loader, transportation of rock from the quarry - dump capacity of 15-20 tons
    The general scheme of works for the underground mining area is as follows:
     Trenching and sampling of outcrops and natural clearings planned after the snow and
     defrost the active layer. Layout trims will be done visually on the ground by geologist on the mine site.Estimated volume of exploration work to be completed during the summer season before the snow coverage.
       Core samples from the wells will be delivered by small truck 4 × 4 to the base for the geological records.
      Documented core be tested by cutting a diamond circular saw into 2 parts. One part will be supplied to the sample, the other to remain in the core samples as a duplicate of the boxes. Weight of core samples are 4-5kg.
      Samples will be transported to the laboratory for processing and analysis.
      Processing of the results will be after the finished of field work.
      Geological and technical staff, except for the drilling crew will work on site the entire season without rotaion.
      This will reduce the cost of transporting personnel during the summer season.
    Members of the drilling crew in accordance with the terms of the Contractor will be rotated every 6 weeks.
    To transport personnel and cargo samples will be provided using a helicopter or seaplane.
    Perhaps, the Сontractor will involved for the total field of geological work, from number of local exploration companies engaged in such work.
    We don"t know the price for services of such companies at this stage, so the budget for geological work will be taken the same as listed above.
    The list of equipment and materials, as well as the calculation of the approximate cost to implement the plan of exploration
    The cost of implementation of planned volume of drilling 3000 meters are determined on the basis of proposals received from the company Foraco Drilling Ltd, which has an office in Yellowknife.
    The cost of drilling one meter in diameter HQ is $ 130 for 1 meter. Given the additional costs as provided under the contract (basis of core boxes, well survey),
    the cost per meter we accept as 200 USD per meter, so the total cost of drilling planned volumes is 600 000USD. According to the proposal from Foraco Drilling Ltd all of the drilling crew can complete within 1.5-2 months.
       The samples from the holes will be delivered by pick-up 4 × 4 on the base for the geological records. The documented samples will be cut by the diamond circular saw into 2 parts. One part will be supplied to the sample, the other to remain in the drill core
      boxes as a duplicate.
       Weight of core samples of 4-5 kg, Samples will be transported to the laboratory for processing and analysis. Processing of the results will be conducted after the field work.Work on the sample preparation
    will be carried out on their own during the drilling. Laboratory samples will be transported to the laboratory for the accumulation of the party required for delivery.
    Expenses of analytical assays of 4,000 samples × 20 USD = 80 000USD. The calculation was based on the average value of the analytical samples in the laboratory of SGS, including delivery of samples to the laboratory.
    It will also need to technological research on bulk samples to develop a scheme of ore processing and gold recovery. The cost of the study is approximately 55 000 USD. Results of laboratory studies are planned to cost $ 130 000 USD. The following table summarizes the projected costs of exploration during the first stage:
       Due to the breakdown of exploration stage on the summer and winter periods, the financing of the works will also be carried out in accordance with the schedule of activities, namely:
      1. Summer field season (spring-summer 2012) - costs USD660 000
    2. Drilling operations and analysis (winter 2012-13 period) - USD800 000
    .
    ECONOMIC BENEFITS OF DEVELOPMENT
    .
      The integrated evaluation of investment in the construction of mining and processing enterprise on the basis of the reserves is based on the performance of analog projects
    and model projects and data manufacturers (equipment), as amended by the conditions of the region. We use as a model project the report "Development of group.
      This paper contains the technical and economic calculations of development of small (up to 3 tons of gold) gold deposits, including the main parameters (geological, mining engineering, technological, economic).
    The cost of basic equipment approved according to figures provided by the company "Sandvik" - one of the world's largest manufacturers of mining equipment
    Costs in the construction of utility-auxiliary and service purpose are defined in terms of their share in total costing, according to project-analogues.
       Capital expenditure
    Calculation of capital costs are for the following:
    . 1. Direct costs; 2. Indirect costs; 3. Unexpected costs;
    Direct costs include the costs of construction of the main production facilities (group 1) and auxiliary and service purpose (II group).
    The group 1 include the objects - an underground mine and a mill complex. The expenses of the underground mine are mining and capital works, purchase of mining equipment, and equipment of the surface complex.
    The cost of mill complex includes the cost of the mill modular capacity of 5 - 7 tons / hour, including the parts of large crushing and tailings. The cost of a modular mill plant is estimated at about 1 million USD.
    Indirect costs are, by definition, represent costs associated with implementation of the construction company. To estimate the indirect costs of an empirical set of (Chainikov, Lapin, 2008) we use the ratio: - Installation of equipment - 15 -25% - Laying of pipelines and other communications - 5 -10% Construction of buildings of Mill - 15 - 35% -Construction of auxiliary buildings and structures - 5-15% - Purchase of tools - 5-12% - Design and construction - 10-30% - Contingencies - 0-15%.
    Unforeseen costs, according to project-analogues are accepted at 10% of the amount of direct and indirect costs.
    The estimated capital cost of construction based on the mining reserves of "Thompson - Lundmark" are 9 708,05 thousand USD, including: - Direct costs - 4.645 thousand USD - Indirect costs - 4.180 thousand USD - Unforeseen costs - 882.55 thousand USD
    Operating costs (production costs)
    In accordance with the methodological terms, the cost structure can be identified:- Costs of production;- Depreciation;
      Taxes and fees included in cost of production.Production costs, the place of their appearance and transfer to production costs, in turn, are subdivided into: -Direct(operational) - Departmenta(operational); - General business Other.
    .
    Direct and departmental costs can be defined as the production costs of redistribution.
    The analysis shows that the average percentage of the total costs of redistribution, general and other expenses in the total calculation for small mining enterprises is 75%: 20%: 5%.
    We have taken the size of annual production costs of commodity products, designed for field "Svetloe", located in Susuman district of Magadan region and very similar to the geological and economic parameters
    (gold reserves 3 tons of ore bodies with vein width ~ 1 m, underground mining method, the productivity of mill factory of ore 50 000 t / year) - 90 USD per 1 ton of ore. The cost structure in this case is as follows:
    . -Production - 30%
    . -Processing of ore - 20%
    . -Other expenses - 5%
      But exclude: depreciation and taxes and fees
       Based on the projected capacity of 50 000 t / year, annual operating costs will amount to 4, 50 million USD.
       The cost of exploration in the cost structure laid down at the rate of USD 200 for 1 meter exploratory core drilling.
      With a planned volume of exploration drilling 3,000 m / year on exploration costs will amount to 600 thousand USD.
      In addition to exploration activities should be planned amount of 400 thousand USD per year to carry out sample assaying and laboratory studies.
      Total operating costs and exploration costs will amount to 5, 50 million USD / year.
      Given to the fact that the mine site "Thompson - Lundmark" is located in a much more favorable conditions than the objects of the Central Kolyma region (Far East-North Russia),
    and the productivity is higher in Canada than in Russia, the proposed value of operating costs has the necessary "flexibility" and the margin of safety.
      This assumption is supported by a number of the tables below, where the main indicators of change such as the price of gold and the cost of operating costs (direct costs) to extract and recycle 1 ton of ore.
    The price of gold varies from $1200 per ounce to $1800 (in increments of $200), and the cost of the direct costs varies from $90 per ton to $150 per ton (in increments of $20).
    The following table shows the main technical and economic parameters of the project at the price of gold per ounce in 1200 dollars (at the cost of direct costs - 90 dollars per ton):
      As mentioned above the main indicators are used with price of gold as 1400 USD per oz. and the cost of direct operation as 90 USD per ton.
    The simple payback of the project is 4.0 years since its implementation, internal rate of return of 41%.
    The total discounted profit for the period of production 7,850 million USD.
    A relatively small amount of work carried out within 1-2 years, can yield growth stocks in 2 - 5 tons of gold at an average grade of the ores 10-15g/t.

    Revenue для производственной компании есть выручка от основной деятельности, т.е. цена одной единицы продукции, умноженная на количество проданных единиц товара.
    После вычесления из revenue (валовую прибыль) gross profit, получится показатель, называемый income from operations, или 'доход от основной деятельности'.
    Если добавить сюда все остальные доходы (other income, или non-operating income), не связанные с основной деятельностью и отнимем непроизводственные расходы, в том числе общие и административные, амортизацию и налоги, то получим чистую прибыль, или net profit.
    Income - это любой доход, как от основной, так и от прочей деятельности. Income всегда связан с денежными потоками (cash flows) Income может быть net и gross.
    Gross income - это валовые доходы от одной или нескольких категорий.
    Net income - это валовые доходы минус расходы.
    Profit - это 'сухой остаток'. Net profit мы получим после вычета всех видов расходов. При переводе, profit всегда переводится 'прибыль', а income всегда переводите 'доход'.
    Gains по-русски тоже называют прибылью. Антоним gains - это losses, (учёт потерь)
    Returns. Это связано с инвестициями. По-русски return on investment могут называть 'доходностью инвестиций', 'доходом от инвестиций' или 'прибылью на капиталовложения'.
    Earnings - Cвязано с распределением прибыли. Когда предприятие получило net profit (чистую прибыль) её распределяют в виде дивидендов (earnings per share, или 'прибыли на акцию),
    либо переводят ее в резерв нераспределенной прибыли в капитале (retained earnings in equity). Либо предприятие может часть прибыли распределить в виде дивидендов (distribute as dividends),
    а оставшуюся часть перевести в нераспределенную прибыль (retained earnings). .
    Gross domestic product (GDP) ВВП (валовой внутренний продукт, или - это совокупная рыночная стоимость всех товаров и услуг, за период. ВВП определяется на государственном уровне (national level)
    Balance of Payments - это разница между экспортом и импортом.
    Consumption (потребление) - это все товары и услуги, приобретенные частными потребителями.
    Investment (инвестиции) - это приобретение (теперь уже и частными потребителями, и организациями) капитальных объектов (capital items): зданий, строительных работ, производственного оборудования
    (plant & equipment), жилой недвижимости (residential property).

    Gold in Canada Gold mines [Интернет]

    Первый рудник в Онтарио [А. Кахаров]
    .
     Gold is found across the Canadian Shield, in British Columbia and Nunavut, and on the
    island of Newfoundland. It was first discovered in Canada in 1823 along the shores of
    the Rivière Chaudière in the Eastern Townships of Québec.
      In 1858, following the famous rushes in California and Australia, gold was discovered in the sands of the Fraser River in the interior of BC, starting the "Cariboo Gold Rush" Almost 40 years later,
    the legendary "Klondike Gold Rush" in the Yukon marked the beginning of one of the most productive periods in Canadian gold-mining history.
       Ontario's first gold rush occurred in 1866, near today's town of Madoc. There have been several other gold rushes and mineral discoveries in Ontario since then many of which still produce gold.
     The early 1900s saw the establishment of several major gold-mining camps in northern Ontario, including Porcupine, Temmins, Larder Lake, Kirkland Lake and Red Lake.
    The Larder Lake area in 1906 was the scene of the first gold rush in northeastern Ontario. Prospectors fanning found gold on the shore of Larder Lake, which became the Kerr Addison mine.
    The gold for the first five dollar gold piece minted in Canada from Canadian gold (issued in 1909) came from the Kerr Addison property.
    Also in 1906, gold was discovered at Swastika 5 km west of Kirkland Lake. In 1911. Bill
    Wright discovered gold at Kirkland Lake.

    Kirkland Lake [А. Кахаров]
    .
    The first gold production in the Kirkland Lake area from the Toburn property was in 1913, from Teck-Hughes in 1917, Lake Shore in 1918, Kirkland Lake Gold in 1919, Wright-Hargreaves in 1921, Sylvanite in 1927, and Macassa in 1933.
    It was not until 1936 that sufficient tonnage of ore was indicated at the site of the original Larder Lake discovery, in what then became known as the Kerr Addison mine, now a past producer.
      Production reached an all-time high of 166 tonnes in 1941 but then declined dramatically because of wartime conditions.
    By 1970 rising production costs had forced the closure of many gold mines in Canada and production dropped to one-third of peak levels.
    Changes in international monetary policies led to a startling increase in gold prices in the late 1970s which, in turn, encouraged increased activity in gold exploration and new mine development.
    The 1981 discovery and subsequent development of the large Hemlo gold deposit in northern Ontario, followed by other discoveries and developments in each of Canada's provinces and territories,
    resulted in increased production and a renewed importance of gold to the Canadian economy.
    Gold production reached nearly 175 tonnes in 1990 and 1997 and 150 tonnes in 2001 before falling in consecutive years to a 22-year low in 2008, at 94.8 tonnes.
    Roughly 90% of Canada's gold production comes from hard-rock underground and open-pit mines.Most production comes from Ontario and Québec.
