Tyhee's 1.6 million ounce s of M&I resources were converted, in the PRE-Feasibility Study, to 810,000 ounces of RESERVES. That's about a 52% conversion rate.
Whereas, from Romarco's Feasibility Study, 2.2 million ounces of M&I resources were converted to 1.3Moz of RESERVES, a rate of about 59%. That's higher than Tyhee's although their grades were lower.
It'll be interesting to see if Clan's resources will have a higher conversion rate. We already see that its average grades are higher than Romarco's (so far), Ormsby and Nick Lake.
