2020-6-24 · 2020-6-24 · The Sterling Mine in Beatty, Nevada (Cathedral Gold Corporation) began life as an underground mine, with a reserve of 100,000 tons of ore at a grade of 11 grams gold/tonne (0.35 oz/ton). Over a fifteen year period, it mined and processed nearly one million tons, but never had enough ore reserves to justify a conventional mill.
This would generally be considered a very high-grade ore, worth mining in most cases. Using this hypothetical value of 1 ozt./ton, each pound of ore would contain approximately 0.0005 ounces of gold. Now let''s assume that gold is valued at $1500 per ounce.
