  "account": "A preliminary economic assessment (PEA) for Silverco Mining's La Negra mine in central Mexico reveals the mine to be highly valuable and capable of generating substantial returns relative to its costs. Assuming a 5% discount rate, the mine's past-producing underground operations are estimated to have a post-tax net present value of $329 million (C$460.7 million) and an impressive post-tax internal rate of return of 131%. Initial costs for the mine are approximately $21 million.\n\nThe low relative costs of the mine can be attributed to its existing infrastructure. Silverco CEO Mark Ayranto highlighted that La Negra has a long history of reliable silver production, and this PEA outlines a clear path to achieving historic production levels with low capital expenditure. The company aims to return the mine to commercial production by the second half of 2027.\n\nThe mine's history spans over 8.2 years, during which it operated underground starting in 1971 under Mexican miner Peñoles. Located in Querétaro state, about 160 km north of Mexico City, La Negra has experienced intermittent mining and several changes in ownership over the past century. The modern underground operation holds the potential to produce 19.3 million oz. of silver, 39.8 million lb. of copper, 93.5 million lb. of lead, and 197.1 million lb. of zinc over its 8.2-year life.\n\nThe PEA includes a resource estimation of 15.2 million indicated tonnes, grading 106 grams of silver per tonne, 0.59% lead, 1.81% zinc, and 0.47% copper. This equates to 51.9 million oz. of silver, 199 million lb. of lead, 608 million lb. of zinc, and 158 million lb. of copper. Additionally, the inferred resources total 2.2 million tonnes, grading 92 grams of silver, 1% lead, 1.92% zinc, and 0.21% copper, which amounts to 6.7 million oz. of silver, 49.7 million lb. of lead, 95.7 million lb. of zinc, and 10.6 million lb. of copper.",
