Pure Gold Mining Inc. (TSXV:PGM) released preliminary metallurgical test results from its Ontario-based Madsen gold project. The results will form part of an ongoing definitive feasibility study for the asset.

Highlights include:

  • High gold recoveries from samples tested average 95.4%, with a range from 90% to 99%, and an average of 36% reporting to the gravity circuit
  • Preliminary gold recovery in the 8 Zone exceeds 99%
  • All tests show low reagent consumption

The press release also states:

These results are part of a comprehensive ongoing metallurgical program designed to define the processing parameters, establish grade-recovery relationships and to optimize gold recovery for the existing Madsen milling circuit.  Importantly, results herein are consistent with the excellent historical production recoveries achieved at Madsen1 and open potential opportunities for further optimization.

In addition to returning high gold recoveries, with a material proportion of the gold reporting to the gravity circuit, the preliminary results demonstrate low reagent consumptions with an arithmetic average of 0.63 kg/t sodium cyanide and 0.25 kg/t lime. The average Bond mill work index of the 12 composites tested was 14.5 kWh/t.

Ken Donner, vice president, operations at Pure Gold, commented:

These results provide very strong support for an improvement on the more conservative recovery estimates employed in our PEA of 92%, and are very much in line with the higher recoveries realized from 36 years of continuous historical production at Madsen. These initial tests were run using historical operating parameters to provide a baseline for further optimization tests aimed at improving recoveries from all zones.
