Excellon Drills 1,293 g/t Silver Equivalent Over 6.5 Metres At Platosa

Toronto, Ontario – April 22, 2021 – Excellon Resources Inc. (TSX:EXN, EXN.WT; NYSE:EXN; FRA:E4X2) (“Excellon” or the “Company”) is pleased to announce results from underground expansion and exploration drilling at the Platosa Mine in Durango, Mexico.


  • Further definition and expansion of the Guadalupe North, 623, NE-1 and NE-1S mantos, with results from underground drilling including:
    • 1,293 g/t silver equivalent (“AgEq”) over 6.5 metres (618 g/t Ag, 10.1% Pb and 12.0% Zn) in EX21UG565;
    • 1,571 g/t AgEq over 4.6 metres (688 g/t Ag, 14.5% Pb and 14.9% Zn) in EX21UG564; and
    • 1,031 g/t AgEq over 4.6 metres (359 g/t Ag, 4.9% Pb and 15.9% Zn) in EX20UG522A, including 1,531 g/t AgEq over 1.3 metres (573 g/t Ag, 8.6% Pb and 21.5% Zn)
  • Drilling continues to outline and expand mineralization within and around the Platosa deposit with new opportunities identified in the historically-mined Guadalupe North Manto.

“Underground drilling at Platosa continues to delineate high-grade silver,” stated Ben Pullinger, Senior Vice President Geology & Corporate Development. “We are currently advancing development to support further drilling of the Gap Zone. As that development progresses, we are identifying areas of historical production where we see potential additional high-grade mineralization, such as Guadalupe North.”

  1. From-to intervals are measured from the drill collar, with drill holes marked UG or PH drilled from underground stations.
  2. All intervals are reported as core length with true widths estimated to be between 50% and 95%.
  3. AgEq in drill results assumes $24.00 Ag, $0.90 Pb, $1.20 Zn and $1,800 Au with 100% metallurgical recovery.

Drilling from underground continues to define and expand known mineralization ahead of production at Guadalupe North, 623, NE-1, and NE-1S Mantos. Most significantly, the Gap Zone (see figure 1), a zone of vertical mineralization inadequately tested with vertical holes drilled from surface, provides an opportunity to add mineralization along a target approximately 300 metres along strike with a vertical extent of 30-40 metres. This target is a priority for the 2021 program and remains open to the south of the deposit, where drilling from surface at the 10-20 target has intersected mineralization beyond the current extent of the Platosa mineral footprint. Development is underway to support underground drill stations for the next phase of drilling on the Gap Zone.
