Silverco Releases Positive PEA for Producing La Negra Mine Outlining a Low Capital, 8.2 Year Mine Life Generating After-Tax NPV of $329 Million

Silverco Mining Ltd. (SICO) released an independent Preliminary Economic Assessment (PEA) and an updated Mineral Resource Estimate (MRE) for its 100%-owned La Negra Mine in Querétaro, Mexico. The base case outlines an 8.2-year mine life producing an average of 4.1 million ounces of silver equivalent (AgEq) annually at a steady-state throughput of 2,500 tonnes per day (tpd) beginning in the second half of 2027.

Life-of-mine economics show an after-tax net present value (NPV) of $329 million and an internal rate of return (IRR) of 131% at a $50/oz silver price, with a payback period of 2.0 years. The life-of-mine average all-in sustaining cost (AISC) is $24.86 per AgEq ounce payable, with initial capital requirements of only $20.9 million.

The updated MRE, effective July 1, 2026, reports Indicated resources of 15.23 million tonnes at 201 g/t AgEq (98.2 million AgEq oz) and Inferred resources of 2.26 million tonnes at 174 g/t AgEq (12.6 million AgEq oz).

Operational catalysts include a new Epiroc underground fleet arriving in the fourth quarter of 2026 or first quarter of 2027, a dry-stack tailings facility targeting completion in the first half of 2027, and a 15,000-metre exploration program already underway. The company reaffirms its target to restart the Cusi Silver Complex in the second half of 2026.

Silverco Mining Ltd. (SICO) released a Preliminary Economic Assessment (PEA) that outlines a low-capital pathway to expand its La Negra asset from its current capacity of approximately 55% to 2,500 tonnes per day. The study addresses previous market inquiries regarding the asset's potential for growth.

The assessment projects strong economics, with an all-in sustaining cost (AISC) of $24.86 and initial capital expenditure of $20.9 million. This technical deliverable follows the company’s acquisition in May and aligns with operational updates previously provided to the market.

Following the earnings release, the stock has consolidated in the $9.00–$10.50 range, indicating that the market has already priced in the acquisition and the scaling thesis. The PEA serves to confirm the existing narrative rather than introducing a new catalyst, with the move expected to align with prior guidance.

Silverco Mining Ltd. (SICO) is transitioning from a developer to a multi-asset silver producer in Mexico. The company’s La Negra Mine in Querétaro hosts a producing underground Ag-Pb-Zn-Cu skarn deposit. Currently operating at 55% capacity, the mine is targeting a throughput of 2,500 tpd by the first half of 2027.

In Chihuahua, Silverco holds the Cusi Mining Complex, a past-producing underground Ag-Au-Pb-Zn project. The asset is fully permitted, with the company targeting a restart in the fourth quarter of 2026 featuring a 1,200 tpd mill. The company’s strategic vision is to become a 10M+ oz AgEq producer within three years through organic scaling and exploration.
