Ask The Experts: How would you go about evaluating a silver deposit?
Any ore grading 32% silver would contain more than 9,000 ounces of silver per ton and be valued at something in the range of $150,000 per ton. Even a few tons of this type of material would be well worth shipping off to a smelter for treatment.
