Aurcana Corporation is a silver/copper/zinc mining company out in Mexico.  Their La Negra mine is profitable and currently their mill is in expansion from 1000 tons per day to 1500 tons per day. It trades around 30 cents and is undervalued.  They also are doing a silver backed financing to get their Shafter Mine in Texas to the production phase.  That mine will increase their silver production 3-4 fold.
