Look at the grades at Bjorkdal (Sweden) and Costerfield (Australia) from the Q1-2017 Mandaly drilling update. Narrow veins but world class gold grades.
Bkorkdal uses Ore Sorting (i.e. GWA.V) to increase head grade-to-mill with the narrow vein mineralization.
Mandalay bottomed last week and this should put a floor on the stock.
Cerro Bayo (one development under the lake collapsed a month ago, sending Mandalay down to 0.35) has not been generating much operational cash flow the last couple years anways so Mandalay's future is in Bjorkdal and Costerfield.
Risk here is any exposure to lawsuits from Cerro Bayo collapse but bottom appears to be in and I added some at 0.39, even after buying at 0.60 before the mine collapse.
