Under various managements they've already had two goes at improving the leaching, although each increased production costs. As for getting income, it has to exceed expenditure for it to work, and AYN has never done that, let alone at $16.50/oz.
C&M until the Ag price gets over $50 is the best bet IMO. Not necessarily with this board, though.
