RE:Why hasn't TUD done metallurgy studies , also has Seabridge SEA has done metallurgical work to a feasibility level over many years. It's critical to determining the viability of a deposit. The SEA work shows KSM can get high recoveries of all metals in a saleable concentrate. No refractory ore.
TUD's met work of two years ago showed the material is refractory...the metal is bound to sulfides and can't berecovered economically. The concentrate is very low grade and would need to be roasted to yield the metal. That was two years ago. The story may be different now but TUD has to prove it. There is no point in calculating all these resources if the metal can't be separated cost-effectively.
