Volcanic and sedimentary rocks filled ranges and basins formed by Tertiary faulting. The Tertiary volcanism initialized gold mineralization approximately 39 million years ago.
In , the open pit mine produced 1,, ounces of gold from The average grade processed is 0. The open pit mine has proven and probable reserves totaling The mine is expected to sustain the current production level for approximately 8 years, based on existing reserves.
Meikle Rodeo deposits. The Meikle deposit occurs in hydrothermal and solution collapse breccias in the Bootstrap Limestone of the Roberts Mountains Formation.
The gold at Goldstrike was carried into the various orebodies by hot hydrothermal fluids, and deposited with very fine pyrite and silica.
Over time, the pyrite oxidized, freeing the gold and making its extraction relatively easy, as in the Post Oxide deposit. In the deeper deposits — Betze, Rodeo and Meikle — the gold is still locked up with the iron sulphide and an additional processing step autoclaving or roasting is required to free the gold.
Two haulage drifts connect the Meikle and Rodeo orebodies. The drifts are accessed from two shafts and by a decline at the bottom of the open pit mine.
Proven and probable reserves underground are estimated at 7. The underground mine, which originally produced at a rate of approximately 2, tons of ore per day, averaged 3, tons per day in Based on current reserves and production capacity, the expected mine life is 9 years.
The ore from all three mines is milled and leached by the cyanide process. Carlin-type gold deposits host gold mainly as microscopically fine grains.
The ore of all three mines is milled and heap leached with the cyanide process. The Carlin-type gold deposits host gold mostly in invisible fine grains.
For the extraction the milled gold ore is leached with toxic cyanide in the process. In this process large amounts of cyanide containing waste water has to be stored in ponds after the gold is separated from the water.
The ore is grinned and then either leached in autoclaves or with heap leaching techniques. For the leaching the ore is put on plastic foil to prevent contamination and to drain the gold containing leaching solution.
The cyanide containing liquid is applied to the top of the heap and the liquid slowly passes the heap. Geology: Like most Carlin type gold deposit in Nevada the gold was epithermally deposited in carbonate or silicate sedimentary rocks.
The source of the heat is magmatic but the exact mechanism is still under debate. The Betze Post deposit is up to m thick and spans between m width with a length of m.
The average gold amount per tonne of ore is 0. Here's the our members favorite photos of " Mines in Carlin ". März um Uhr. Y sagte:. Oktober um Uhr.
