I succeed to own 70% of total market for silver watch. But my silver mine empty too quickly. it make no sense to have to open a new mine every year. I have no time to amortize the cost of opening mine on only 1 year. The cost for a mine should remain the same but the reserve of mineral should be at least 3 to 5 time more important to be realistic.
My researche on google show that silver mine for instance may have up tu 57 million oz.
