Trigon Metals reported on Monday that total mineral resources at its Kombat copper project in Namibia are now estimated at 39.1 million tonnes (including inferred resources), up more than 450% from the 7 million tonnes calculated in 2018.
Earlier this month, Trigon outlined the upside potential on Kombat’s mineral resources based on additional mineralized underground drill holes, identified outside of the holes in the existing database.
A total of 3,758 additional mineralized underground drill holes have now been incorporated outside of the holes utilized in the 2018 mineral resource database, leading to a 152% increase in the volume of the resource shell and three-dimensional confirmation of material not removed by past mining.
According to the company, the previous mineral resource of 7 million tonnes represented between 18% of the pre-existing geological model used for resource reporting, with the remaining 82% of the tonnage based on drill holes not previously included.
Additional work completed includes improving the level of accuracy of depletions in underground areas.
The Kombat mine, located in the Otavi Mountain region, is a historical mine that operated from 1962 to 2008, during which it produced 12.46 million tonnes grading 2.6% copper.
Last week, Trigon expanded its project portfolio by acquiring the Silver Hill copper-silver project in Morocco. The company followed up the acquisition by completing a $4.8-million private placement, in which mining investor and shareholder Eric Sprott participated.
