Trigon Reports Significant Increase in Indicated Resources at Kombat Mine, Namibia

TORONTO, ON / ACCESSWIRE / Aug 3, 2021 / Trigon Metals Inc. (TSX-V: TM) (“Trigon” or the “Company”) announces an updated NI 43-101 Mineral Resource Estimate at the Kombat Mine in Namibia (“Kombat” or the ” Project”). The combined estimates of surface and underground indicated mineral resources reached 12.2 million tonnes at 1.94% copper, 13.65 g / t silver and 0.70% lead, compared to the estimate of open-pit indicated mineral resources strictly of 7.35 million tonnes at 0.91% copper, 0.58 g / t silver and 0.88% lead announced (see press release dated October 29, 2020 ).
Jed Richardson, President and CEO of Trigon, said, âWe have our licenses, we have our team and now we have our resource. Our reported tonnage has increased by 66% over our previous mineral resource estimates. Our tonnage of 113% copper and silver increased by 2,253%. We have succeeded in increasing the quality of our resources by all means, despite stricter cut-off grades by demonstrating the importance of the underground resource. We remain on track for first production and shipping of concentrate by the end of the year. “

The updated mineral resource estimate is the culmination of 18 months of work, the first mapping of historical drilling and historical mining production in three dimensions, as well as the re-logging and analysis of 50 years of core stored boreholes. The work confirmed historical assay results for copper and analyzed silver for the first time, converting 86.5% of the world’s resource to the measured and indicated confidence level of a mineral resource estimate. NI 43-101.
The Company used more stringent criteria to calculate the cut-off grades and removed the influence of lead when calculating the copper equivalent cut-off given the abundance of copper and silver mineralization and the focus on on profitable and sustainable production. The new criteria have the effect of increasing the copper content in the surface mine and limiting what qualifies in tonnes of estimated mineral resources. The result is a robust estimate of surface and underground mineral resources that is expected to provide more than 20 years of expected production levels. Initially, lead will not be recovered when surface mining resumes, as the preference is to optimize recovery of copper and silver, which are much more valuable throughout the life of the mine. .
The presentation of these mineral resource estimates marks the first comprehensive estimate of silver grades at Kombat, generating an in situ Indicated Mineral Resource estimate of 5.3 million ounces of silver, a byproduct of 482 million pounds. of copper in situ contained. Metallurgical testing and anticipated mine dilution predict an estimated copper recovery of 85% and silver recovery of 88%.
The mineral resource estimates have been prepared and classified by Minxcon in accordance with the reporting guidelines required by the Canadian Securities Administrators.

About the Kombat mine
The Kombat Copper Project is Trigon Metals Inc.’s flagship project, with the company’s mining and prospecting license areas covering an area of ââover 7,500 ha in the Otavi Mountains of Namibia. The Kombat project includes three mining licenses, which produced approximately 12.46 million tonnes of copper between 1962 and 2008, at a grade of 2.62%. The other two mining licenses are in the immediate vicinity of Kombat at Gross Otavi and Harasib, which are considered very promising for lead and zinc. In addition, the Company also holds an interest in two exclusive prospecting licenses, which represent a potential extension of the Kombat strike.
