- Classic Minerals (CLZ) confirms an average head grade of 6.06 grams of gold per tonne in its first bulk sample ore from Kap Gap in WA
- The company received assay results from its recent Gekko pilot plant test work, which reported a JORC resource higher than originally calculated
- The company calculated a recovery of 73.2 per cent into a mass pull of 4.6 per cent of the feed
- Classic says the new run demonstrates the Gekko flowsheet effectively concentrates the gold ore to produce a high-grade concentrate, whilst discarding a proportion of the gold into a low-grade tailings stream
- Classic Minerals ends the day in the grey to close at 1.7 cents
Classic Minerals (CLZ) has confirmed an average head grade of 6.06 grams of gold per tonne in its first bulk sample ore from Kap Gap in WA.
The company received assay results from its recent Gekko pilot plant test work.
Classic Minerals reported an original JORC resource of one million tonnes at three grams per tonne (g/t) gold for 93 thousand ounces, however, the actual grade calculated from the pilot plant of 6.06 g/t gold was much higher than the average inferred resource grade calculated back in April.
The gravity gold recovery was in line with expectations, with a recovery of 73.2 per cent into a mass pull of 4.6 per cent of the feed.
This compares against the previous bench scale metallurgical test work of 65 to 75 per cent gravity gold recovery in around five per cent mass pull.
The company said the run demonstrates the Gekko flowsheet effectively concentrates the gold ore to produce a high-grade concentrate, whilst discarding a proportion of the gold into a low-grade tailings stream
Chairman John Lester said the company is ecstatic about the high grades coming from the metallurgical reports.
“We were aware that there was a high degree of gravity recovery from the Kat Gap ore but the 73.2 per cent is admirable,” he said.
“Furthermore, the met test results showing a 98 per cent recovery of gold from Kat Gap ore will mean that this extent of recovery can be repeated during any toll milling that may be undertaken while we are waiting for all our processing licenses.
“I believe that the Kat Gap Plant will be in the lower cost quartile due to the beneficiation of the ore prior to gold recovery.”
Classic Minerals ended the day in the grey to close at 1.7 cents.
