The KE Report Excellon Resources – Flagship Mallay Silver Mine Going From Development Into Production Ramp Up, Exploration Update, and Value Drivers At 3 Other Projects
Shawn Howarth, President and CEO of Excellon Resources (TSXV:EXN) (OTC:EXNRF)(FRA:E4X2), joins me to outline all the development work going into the ramp up into production over the next few quarters at their flagship Mallay Silver Mine located in the Cerro de Pasco area of Peru. We then review the value proposition and optionality across their other 3 projects: Tres Cerros, Kilgore, and Silver City.
Excellon acquired the Mallay Silver Mine last year as a modern, fully permitted past-producing underground mine with a 600 tpd processing facility; that was built and operated by Buenaventura from 2012 to 2018. With US$115 million of historical investment and sunk costs, supported by an extensive drilling and operating database generated during Buenaventura's ownership, the Excellon team has many advantages here and a low capex investment to get back into commercial production.
In February 2026, Excellon released the updated NI 43-101 Mineral Resource Estimate:
Mallay MRE Highlights:
- Indicated Mineral Resources: 890,000 tonnes grading 195 g/t silver, 3.33% lead and 4.83% zinc. The Indicated mineral resource includes 5.57 Moz of silver, 65 Mlbs of lead and 95 Mlbs of zinc.
- Inferred Mineral Resources: 362,000 tonnes grading 149 g/t silver, 2.67% lead and 4.32% zinc. The Inferred mineral resource includes 1.74 Moz of silver, 21 Mlbs of lead and 34 mlbs of zinc.
- Mineral Resource (AgEq): 12.01 million ounces grading 420 g/t AgEq in the Indicated and 4.00 million ounces grading 344 g/t AgEq Inferred.
Shawn highlights the ongoing exploration program focused on the mineral resource expansion potential in the known Isguiz Zone inventory, as well as the Footwall Zone and Shafra Zone.
In 2025, Excellon secured an off-take agreements with Glencore for their lead and zinc concentrates, Shawn outlined that their internal studies project a run-rate of 600 tonnes per day of production, producing approximately 2-2.5 million silver equivalent ounces per year, and with a target All-In Sustaining Cost (AISC) of US$17 per AgEq ounce.
The Tres Cerros Project is a highly prospective gold-silver exploration project approximately five kilometers northwest of the Mallay Mine. The project’s prime area of interest is a 2.5 kilometer by 500 meter corridor of gold-silver mineralization and coincident IP/resistivity anomalies, indicative of a bulk tonnage, high sulfidation epithermal system. Numerous historical grab samples were taken across the 2.5 kilometer fault, which are being analyzed to determine further follow-up exploration work.
Kilgore, is an advanced gold project in Idaho with over 1 million ounces of gold delineated in all categories, and the Company is considering bringing in a JV partner to assist with moving this project forward in exploration and further derisking. Silver City, a high-grade epithermal silver district in Saxony, Germany, with a long history of almost 800 years of silver production. Shawn has stated publicly that they are looking at various options, but are entertaining the idea of spinning out this asset into a new European-focused exploration vehicle.
Wrapping up we reviewed the industry experience the Excellon management team and board has in both moving projects into production as well as a pedigree of exploration success. We discussed that the company is cashed up after their financing and off-take agreement, to conduct the key work and studies on tap over the next 6-9 months as the company moves toward a production decision.
