Overview: A preliminary evaluation has been carried out for the commercial potential to treat Sudbury pyrrhotite tailings.  The evaluation is based on available test results carried out Vale, and feeding these results into a quantifiable detailed energy balance and process model.  The results show: 55% IRR for any feed grade >0.8% Ni, using conservative metal prices of $5/lb Ni, $15/lb Co, $1.50/lb Cu and $850/oz for combined PGM (~5:1… Read More »Take the risk or lose the chance

Summary: An order of magnitude capital cost has been extrapolated from previous projects, and adjusted for the inflation of steel and concrete prices, which approximates to $20 million for a 200 tonne/day treatment plant at >90% recovery at high purity. Using this value, and assuming fixed operating costs to be the same as the variable costs, then a series of IRR calculations was carried out.  The results indicate a favorable… Read More »And so the adventure begins

Project: SUDBURY TAILINGS (Vale)

Value Proposition: No play No pay modular refining unit – treatment of tailing stockpile, complete removal of all toxic materials, gangue, and recovery of heavy metals and value minerals including arsenic, sulphur, lead, cadmium, nickel, cobalt, copper, iron, PGMs etc.

Skid mounted on-site processing plant.

No front end capital risk for Vale, deal contingent only upon meeting/surpassing pre-agreed upon performance guarantees.Read More »Actually, you can
