For a mineral deposit to be large enough to mine, it must be able to produce enough of whatever is being mined to offset, with a profit, the cost of extracting, transporting, crushing, processing, and finally refining. A deposit does not have to be large to be economically feasible. A single yard of material in an outcrop of rock that will yield 1/2 oz or more of Gold is well worth busting out of the ground, If you have knowledge of how to process it, or know of some smelter operation, or refiner that will buy it, or process it for a percentage of the gold recovered.
