A very partial answer:
Depends on the price of gold, the cost of labor and production at the mine, taxes, cost of adhering to environmental regulations, available gold-refining techniques, and other economic variables in addition to grams per ton.

You can mine gold down to about 0.5 grams per tonne if the mining and processing costs are low. Sometimes companies re-mine old waste dumps and just wash and pump the fine dump material into the process plant. This is a cheap way of mining.
Gold mining in South Africa is done at about 3 km depth and the costs are high. Probably would need several grams per tonne of ore to justify such deep mining.

listed under are the conversions which you will choose alongside with a physically powerful calculator: a million ton = 2000 kilos a million pound = sixteen ozSo i think of you are able to take the a lot of gold mined and multiply by utilising 2000 multiply by utilising sixteen and then multiply by utilising the fee consistent with ounce. that's alot of money. wish this helps.

as stated above, there are lots of factors that go into the economics of mining. but as one example, the cutoff grade of one open pit gold mine in the us I worked at is 0.007 Troy oz/ton.
