Troilus Gold recovers 93.5% Cu, 88.3% Au at Troilus

Mr. Justin Reid reports


Troilus Gold Corp. has released excellent metallurgical recovery results for the Southwest zone as part of a continuing pilot-plant-scale metallurgical testing program on each of the main mineral deposits at its 100-per-cent-owned Troilus project, located in north-central Quebec, Canada. Approximately nine tonnes (9,000 kilograms) of sample material, approximately three tonnes from the three main mineral zones (zone Z87, J zone and Southwest zone) were sent to Eriez’s metallurgical test facility in Erie, Pa., last year to validate the recovery of gold, copper and silver using standard gravity and column flotation technology. The results of these test programs will be used to support the coming prefeasibility study as well as future economic studies.

Southwest zone test program overview and results:

  • An approximately three-tonne (3,000-kilogram) composite sample of mineralized material from the Southwest zone, prepared using coarse assay rejects from the various domains of the entire mineralized zone, was provided to Eriez for testing.
  • Overall copper recovery of 93.5 per cent, gold recovery of 88.3 per cent and silver recovery of 89.4 per cent was achieved in combined gravity separation and rougher scavenger cleaner column flotation, an industry-standard processing method.
  • These results are consistent and generally exceed the recoveries used in the preliminary economic assessment (refer to press release dated Aug. 20, 2020), where the recoveries for copper and gold were 90 per cent and silver was 40 per cent.

Justin Reid, chief executive officer and director of Troilus Gold, commented: « We are very pleased with the recovery results from the Southwest zone, which are consistent with those released a few months ago from the J zone. The Southwest zone is located approximately two kilometres away from the formerly mined pits and was only discovered about two years ago, so, for the metallurgical results from this area to be in line with previous work and new results from the main zones is very encouraging. »

On Feb. 28, 2022, Troilus released excellent metallurgical test results for the J zone of gold, copper and silver recoveries of 92.9 per cent, 90.4 per cent and 88.8 per cent, respectively. Continuing testing is being completed on the third and last sample for zone Z87 and will be released once complete.

About Troilus Gold Corp.

Troilus Gold Corp. is a Canadian-based junior mining company focused on the systematic advancement and de-risking of the former gold and copper Troilus Mine towards production. From 1996 to 2010, the Troilus Mine produced +2 million ounces of gold and nearly 70,000 tonnes of copper. Troilus is located in the top-rated mining jurisdiction of Quebec, Canada, where is holds a strategic land position of 1,420 km Superscript 2 in the Frotet-Evans Greenstone Belt. Since acquiring the project in 2017, ongoing exploration success has demonstrated the tremendous scale potential of the gold system on the property with significant mineral resource growth. The Company is advancing engineering studies following the completion of a robust PEA in 2020, which demonstrated the potential for the Troilus project to become a top-ranked gold and copper producing asset in Canada. Led by an experienced team with a track-record of successful mine development, Troilus is positioned to become a cornerstone project in North America.
