what do you know about this ? 300 ounce silver per ton and gold strike.

  • New discovery of very high-grade silver vein structures approximately 55 meters southwest of the #3 Shaft where a silver discovery in 1979 put the Castle mine back into production for a decade - CA-18-54 cut 93.7 ounces per ton Ag (3,213 grams per tonne) over one meter including 286.3 ounces per ton (9,816 g/t) over 0.33 meters starting just 9.71 meters downhole, with the hole drilled across the structure at 25o to core axis and then bottoming in high-grade mineralization from 18.84 meters to 20.50 meters;
  • 385.2 ounces per ton silver (13,208 g/t), 0.67% cobalt and 3.77 g/t gold over half a meter within a broader 5.51-meter zone that also included 1.87% cobalt over 2.54 meters and 76.4 ounces per ton Ag (2,620 g/t) over a core length of 5.51 meters starting at just 1.46 meters (CA-18-02, collared near the adit entrance, was drilled perpendicular to the strike of the targeted vein structure, sub-parallel to the dip of the vein);
  • All 47 assayed shallow underground test holes intersected cobalt mineralization with an impressive one-quarter of those holes returning high-grade intercepts of 1.05% to 3.7% cobalt over an average core length of 1.77 meters (true widths unknown at this time);
BMRs take.... Fascinating CCW news…some key takeaways…– Not hard to do the math here – minimum 600 tpd, and historic records show the coarse stamp mill tailings are very high in Silver (in the several ounces per tonne), and also contain some Gold and Cobalt, and this is supported by SGS assays which returned a gravity concentrate of 389 g/t Ag, 0.63 g/t Au and 0.20% Cobalt…– Tailings are just 300 meters from Shaft #3…one of the biggest costs in mining is moving rock…none of that here…looks like a very simple pumping of the tailings down Shaft #3 to CCW’s newly acquired gravity spiral concentrators underground…these are amazing units, you can check them out at Mineral Technologies’ web site…extremely efficient, low maintenance, high recoveries, low cost…tailings waste is put into the stopes (cemented tailings) after the stopes are cleaned out, providing CCW with more material from underground (stopes are mineralized)…– Spiral concentrators turn material into very high-grade concentrate…from there, you can take it to a smelter and start pouring Silver and Gold bars…the Cobalt will come into play through Re-2OX but the immediate easy opportunity to generate cash flow through the Silver and Gold is huge…– Should be high margin operation to clean up tailings – at 600 tpd, the potential monthly cash flow would be in the order of $750,000 to $1 million based on a conservative Silver grade of 3 ounces per tonne, plus some Gold…– Timing on all this is relatively quick, through an amendment to existing permit…– Here’s the real kicker – a successful tailings program at Castle can be replicated elsewhere in the district…this is also what will bring in privately held Battery Mineral Resources…they have a lower grade (not the coarse stamp mill tailings CCW has) but larger deposit on their ground (43-101 resource) adjoining Castle…plus, opportunities elsewhere in the district as there are an estimated 200 million tonnes of tailings scattered throughout the Northern Ontario Cobalt Camp…Comment by Jon - BMR — March 1, 2019 @ 2:41 pm
