The cost of building a new large gold mine runs into several hundred million us$. There are just over 4000 mineral species discovered world wide to date. The liquid then cools and hardens. Company geologists regularly visit stopes and development headings to gather samples and map local geology and to give direction to miners. This photo shows the author inspecting some antique mining equipment at Pilgrims Rest. The most common minerals in this group are various sulfides, oxides and native elements. It is interesting to note that, despite the short duration of these historical gold rushes, several new gold mines are planned to open in Alaska and British Columbia over the next few years. These extra-high-grade areas are erratically distributed throughout the mine and often run locally in the many hundreds of ounces per ton over distances of tens of feet. Often, copper makes up a substantial portion of that 7.5%, because it increases the alloy’s hardness. mine and the mineral that is the most interesting to collectors. To reflect that variation, the zones have been grouped into two categories, the high-grade zones (the “High-Grade Zone”) and the sulphide zones (the “Sulphide Zone”). Alteration, metamorphism and structureassociated with Archen volcanic-hosted gold deposits, Red Lake District;studies in the Campbell and A.W. Palladium and iridium are commonly alloyed with other metals or used alone to make jewelry pieces.
