The cost of producing gold is highly variable depending on the mining method and the type of gold deposit. Some gold is found as free gold in rivers, for example, which means that it can be obtained for almost nothing. At the other extreme, there is gold that is locked up in the surrounding rock, at depth, where it has to be mined in a very costly, labour intensive, energy intensive way. It may be difficult to refine and in addition licences and royalties come into the equation. The crux of the matter is whether the production costs are more than the price of gold, in which case it is not feasible to mine it.
No one answer. It would depend on the gold content of the mineral. The higher the gold content, the lower the energy cost. The deeper the mine, the higher the cost.
The marginal cost of production at 300 leather jackets is calculated by finding the difference in total cost when producing one additional unit. In this case, the total cost of producing 301 jackets is $435, and the cost of producing 300 jackets is $400. Therefore, the marginal cost is $435 - $400 = $35. Thus, the marginal cost of producing the 301st leather jacket is $35.

The largest gold producing country in the world is Soth Africa. It is also the largest diamond producing country in the world. It mines more than 100 kg of gold per day. China is largest gold producing country - 403t in 2012.
