Troilus Reports Metallurgical Recoveries Of 95.5% Gold, 95.9% Copper And 92.8% Silver From Zone Z87 Pilot Plant Test Program

July 12, 2022, Montreal, Quebec – Troilus Gold Corp. (TSX: TLG; OTCQX: CHXMF) (“Troilus” or the “Company”) is pleased to report excellent metallurgical recovery results for Zone 87 as part of the recently concluded pilot plant scale metallurgical testing program on each of the main mineral deposits (Zone 87, J Zone and Southwest Zone) from its Troilus Project in northcentral Quebec, Canada. Approximately 3 tonnes of sample material from each of the main mineral zones were sent to Eriez’s metallurgical test facility in Erie, Pennsylvania last year to validate the recovery of gold, copper and silver using standard gravity and column flotation technology. The latest Zone 87 results, along with the metallurgical recoveries for the Southwest and J zones announced earlier this year (see press releases from February 28 and June 28, 2022) will be used to support the upcoming Pre-Feasibility Study, as well as future economic studies.

Z87 Metallurgical Test Program Overview and Results:

  • An ~3 tonne (3,000 kg) composite sample of mineralized material from the Z87 zone, prepared using coarse assay rejects and sawn ¼ core from the various domains of the PEA mineralized zone was provided to Eriez for testing.
  • Overall gold recovery of 95.5%, copper recovery of 95.9%, and silver recovery of 92.8% was achieved in combined gravity separation and rougher-scavenger-cleaners column flotation, an industry standard processing method.
  • These results all exceed the recoveries used in the Preliminary Economic Assessment (refer to press release dated August 20, 2020), where the recoveries for copper and gold were 90% and silver was 40%.

Justin Reid, CEO and Director of Troilus Gold, commented, “The results from this pilot plant metallurgical test work program returned excellent recoveries across all three mineral zones using industry standard and proven processing methods. These new results support, and in most cases enhance, the previous metallurgical test work results completed in 2020, which represents a significant de-risking milestone for the project and sets a solid foundation for the upcoming Pre-Feasibility Study as well as future engineering work.”

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 km² in the Frôtet-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.

Cautionary Note Regarding Forward-Looking Statements and Information

The PEA is preliminary in nature, includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the PEA will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability. The PEA is subject to a number of risks and uncertainties. See below and the Company’s latest technical report available on SEDAR for more information with respect to the key assumptions, parameters, methods and risks of determination associated with the foregoing.

This press release contains “forward-looking statements” within the meaning of applicable Canadian securities legislation. Forward-looking statements include, but are not limited to, statements regarding the potential impact of the test program on the Company and the likelihood that the results projected, including without limitation the recoveries, will be realized on the timeline targeted or at all, timing of future studies including the pre-feasibility study, environmental assessments (including the timing of an environmental impact study) and development plans, opportunity to expand the scale of the project, the project becoming a cornerstone mining project in Quebec and Canada; the development potential and timetable of the project; the estimation of mineral resources; realization of mineral resource estimates;; the timing and amount of estimated future exploration; costs of future activities; capital and operating expenditures; success of exploration activities; the anticipated ability of investors to continue benefiting from the Company’s low discovery costs, technical expertise and support from local communities, ; the timing and amount of estimated future exploration; the anticipated results of the Company’s  2022 drill program and their possible impact on the potential size of the mineral resource estimate; the ongoing impact of the  novel coronavirus (COVID-19) and the  considerable uncertainties about the geographic, social and economic impact on the Company.  Generally, forward-looking statements can be identified by the use of forward-looking terminology such as “plans”, “expects” or “does not expect”, “is expected”, “budget”, “scheduled”, “estimates”, “forecasts”, “intends”, “continue”, “anticipates” or “does not anticipate”, or “believes”, or variations of such words and phrases or statements that certain actions, events or results “may”, “could”, “would”, “will”, “might” or “will be taken”, “occur” or “be achieved”. Forward-looking statements are made based upon certain assumptions and other important facts that, if untrue, could cause the actual results, performances or achievements of Troilus to be materially different from future results, performances or achievements expressed or implied by such statements.
