The Mallay Silver Mine is ramping up. $EXN.V is drilling to find out how much bigger it could become. In this @CruxInvestor clip, President & CEO Shawn Howarth explains what the team is testing beneath the existing workings at our Mallay Silver Mine in Peru. Alongside drilling to extend known mineralized shoots, a deeper program is investigating the potential intrusive source behind Mallay’s vein system. Planned downhole electromagnetic (DHEM) surveys will help guide further drilling and build a clearer picture of what lies below. Shawn discusses why that deeper exploration matters for Mallay’s future, while the immediate priority remains ramping up the mine. $EXN $EXNRF | FRA: E4X2 #Silver #Exploration #Peru #Mining

On site at Tres Cerros, our gold-silver exploration project 6km west of the Mallay Silver Mine in Peru. These photos are from a recent site visit. This year’s field program has defined 7 target areas across approx. 40% of the property, helping guide the next stage of exploration. Initial drilling is targeted for H1 2027, subject to permitting.

Tres Cerros has never been drilled. Excellon is targeting an initial drill program in H1 2027 to test the project’s gold-silver potential. At Precious Metals Summit Beaver Creek, President & CEO Shawn Howarth outlines the opportunity at Tres Cerros in Peru: •⁠ ⁠A 2.5 km exploration corridor with gold and silver mineralization identified at surface •⁠ ⁠Surface grab samples at the Xica target returning up to 14 g/t gold and 9,050 g/t silver •⁠ ⁠⁠ The plan: reinvest cash flow from the Mallay restart into exploration Watch the full presentation: $EXN | $EXN.V | $EXNRF #Silver #Peru #Mining

John points to Mallay’s first concentrate milestone and the operation’s continued progress toward silver production.

Excellon is the newest company featured in Shad Marquitz’s Opportunities in Silver Explorers and Developers series, and he sees the story moving quickly beyond the developer category. Shad describes $EXN as being on the “golden runway” from development toward commercial production, with Mallay advancing through ramp-up and a significant expansion story still to be told through drilling. His thesis also looks beyond Mallay, highlighting the value potential across Tres Cerros, Kilgore and Silver City that he believes is not reflected in Excellon’s current valuation.
