Trigon Metals is going to look for opportunities to grow production from underground, which in turn should increase copper production and profitability, Rennie Morkel, President and Chief Operating Officer has said.
Morkel was speaking subsequent to last week’s announcement that the miner achieved commercial production from the underground operations at its Kombat Mine in Namibia, as of April 30, 2024.
This achievement marked a major step forward in Trigon’s path to becoming a leading mid-tier copper producer.
“Congratulations to our homegrown owner operated underground mining teams. Re-asserting Kombat as an underground copper producing mine is a tremendous achievement for the operation, the company and our community. My sincerest appreciation to the entire Kombat team, under the guidance of our VP Operations Fanie Muller, for their tireless efforts in achieving this important milestone for the future of Kombat,” extended Morkel.
Trigon defines commercial production status as operating at 70% of production capacity over 30 consecutive days. After restarting mining operations from the open pit in May 2023, the Company commenced production from underground ahead of schedule, having announced underground training and the first blast on February 5, 2024. The build-up to commercial production levels has gone smoothly and exceeded Trigon management’s expectations.
Commenting, Jed Richardson, CEO & Executive Chairman, said, “Increased grade from underground has profoundly impacted our metal production, making each tonne more profitable. It has improved recovery in the mill and increased the grade of the concentrate. The Kombat mine has been primarily an underground mine through its 45-year history. Our experience is now showing us why.”
Underground production has resulted in an increase in the Company’s metal output, owing to the higher grade of ore retrieved from the underground. As more high-grade ore tonnes from underground displace lower-grade open pit ore, copper production increases which is expected to translate into lower operating costs.
The total copper production was calculated by adding open pit ore mined and underground ore mined to ore retrieved from the stockpile.
The Company has benefited from the expertise of many experienced miners who have remained in the vicinity of Kombat, dating back to 2007 when the Kombat Mine was last in operation. The operation targeted 500 tonnes per day (“tpd”) underground and 500 tpd open pit production in April to fill the mill’s 1,000 tpd throughput capacity. In April 2024, production from the underground averaged 552 tpd and has continued to exceed expectations, producing more than 1,000 tpd on four occasions in the month of May.
Ore processing occurs at the refurbished Kombat plant, with a current operating capacity of 30,000 tonnes per month (30ktpm). Plans are underway to increase the capacity to 60,000 tonnes per month (60ktpm) to accommodate ore from both underground and surface sources.
Dewatering continues at the Kombat mine, where water is being pumped at a rate of 2,800 m3/hour, well above the in-flow rate of 1200 m3/hour. The mine is now dewatered to 315m below shaft collar. Backup power capacity is in place to ensure an uninterrupted power supply for underground pump systems.
Trigon is a publicly-traded Canadian exploration and development company with its core business focused on copper and silver holdings in mine-friendly African jurisdictions. Currently, the Company has operations in Namibia and Morocco. In Namibia, the Company holds an 80% interest in five mining licences in the Otavi Mountainlands, an area of Namibia widely recognized for its high-grade copper deposits, where the Company is focused on exploration and re-development of the previously producing Kombat Mine.
