Did Trent just drop a little gem in there hidden at the back?  Afterore sorting [of muckpiles], the average feed grade was increased from 0.081% Co and 46 gpt Ag to anaverage of 0.575% Co and 190 gpt Ag. With just that part (and more to come) estimated at 190-290kt that would make it at say 250kt x 85% recovery ~200kt @0.575% = ~ 1,000t of Co @ $70k/t = $70M revenue just there (obviously not profit, but still). Vs an AUD mine start up cost of $35m. Plus the silver!

Was this announced before? Or how come the market has missed this? Or did I stuff up in my calcs? If I'm right this must be by far the best, easiest and most undervalued Cobalt stock out there!
