Ton Ore
Is .245 oz of gold per ton a good quantity for mineral/gold mining?
.245 oz of gold per ton or 7.62 gold grams per ton of ore
and
.435 oz of silver per ton or 13.53 silver grams per ton of ore
Would a mining company be interested in working a mine with these types of results?
Thanks in advance for any information given.
Those gold grades would be considered to be attractive if the following conditions can be met:
1. sufficient tonnage, say a minimum of one million tons
2. No unusual environmental hurdles, eg salmon, condors, marbled murrelets, spotted owls, unstable ground conditions etc close by
3. political and social support
4. good access
5. favorable metallurgical characteristics
6. no undesirable by-products, such as mercury, arsenic, acid generation
7. reasonably priced electricty
0.435 opt silver by itself would not be economic, but if it was combined with the gold then most of it would be recoverable at a profit. You need to look at a minimum gross metal value of about $15 per ton for an open pit mine and $40 per ton for an underground mine.
