MCO immediately prior to going into suspension when promised funding was pulled in 2012 was targetting 80KTPA at 10-12g/t.
If I have calculated correctly that would equate to approx $40 000 000 of gold at $1600 an ounce!
Admittedly al lot of water to go under the bridge before that could be realised - but given mantle is a $3 million market cap company there looks to be plenty of upside in this.
