Excellon Restarts Mallay Silver Mine in Peru
The past-producing silver-lead-zinc mine in central Peru is being brought back into operation as the company pursues free cash flow.
Updated on Nov. 5, 2026 in Construction
Excellon Resources is restarting the past-producing Mallay silver-lead-zinc mine in Peru, an underground operation with existing infrastructure. The company plans to produce a lead concentrate holding most of the silver along with a separate zinc concentrate.
Why it matters
The restart puts a previously producing asset back to work as Excellon seeks to reach free cash flow while redeveloping the broader district. It also reflects continued interest in base and precious metals from central Peru's mining belt.
The Mallay mine includes a 600-tonne-per-day processing plant and roughly 30 kilometres of underground development, with three drill rigs active across the site. Excellon has not disclosed restart production volumes or capital costs in the source material.
The players
Excellon Resources
Excellon Resources is a mining company listed on the TSX Venture Exchange under the symbol EXN that is exploring and redeveloping properties in central Peru.
The details
Excellon is looking for wider mineralized zones at Mallay that could support greater mechanization and keep the processing plant supplied at an average rate of 600 tonnes per day. The company plans to produce a lead concentrate with most of the silver and a separate zinc concentrate.

Market Landscape
Central Peru's polymetallic vein districts have long supported silver, lead and zinc output, and the Mallay restart returns one of those historic assets to production. Excellon's plan to explore and redevelop the wider district places it among companies seeking to expand known mineralized corridors.
For readers following metals markets, the restart signals that Excellon is moving to bring existing silver, lead and zinc capacity back online rather than waiting on new discoveries. Investors tracking the stock will look to upcoming drilling results from the 2027 Tres Cerros program.
The takeaway
Restarting a mine with existing plant and underground development can reduce the time needed to return to production compared with building from scratch. Watch for drilling updates on Tres Cerros as the next indicator of whether the district can support larger operations.
