Toronto, Ontario – October 26, 2021 – Excellon Resources Inc. (TSX:EXN; NYSE:EXN; FRA:E4X2) (“Excellon” or the “Company”) is pleased to announce results from underground drilling at the Platosa Mine in Durango, Mexico.
Highlights
- High-grade results from the 623, NE-1, NE-1S, and Pierna mantos, with diamond drilling results from underground including:
- 3,043 g/t silver equivalent (“AgEq”) over 2.2 metres (2,160 g/t Ag, 24.6% Pb, 7.2% Zn) in EX21UG698;
- 764 g/t AgEq over 7.5 metres (648 g/t Ag, 2.6% Pb, 1.4% Zn) in EX21UG691;
- 1,008 g/t AgEq over 3.4 metres (766 g/t Ag, 4.7% Pb and 3.5% Zn) in EX21UG733;
- 801 g/t AgEq over 3.4 metres (501 g/t Ag, 5.8% Pb, 4.4% Zn) in EX21UG709;
- 5,110 g/t AgEq over 0.5 metres (4,451 g/t Ag, 8.8% Pb, 12.2% Zn and 0.2 g/t Au) in EX21UG706;
- 903 g/t AgEq over 2.6 metres (523 g/t Ag, 3.5% Pb, 8.5% Zn) in EX21UG740;
- Underground drilling continues to define and delineate mineralization to support mine planning;
- Follow-up drilling on vertical zone intersected in hole EX21UG690 (2,860 g/t AgEq over 7.5 metres) is underway with assays pending.
“Drilling at Platosa continues to define and extend high-grade mineralization ahead of production,” stated Jorge Ortega, Vice President Exploration. “We continue to focus on infill drilling to support planning for upcoming and future production, as well as testing the recently discovered high-grade zone – the 817 Zone – below Manto 623. We have now drilled an additional 20 holes on the 817 Zone with assays pending. This zone appears to have a vertical orientation and has the potential to open up a more vertical dimension to the deposit.”

- Highlighted intervals include holes intersecting >0.5m and over 500 g/t AgEq from a total of 22 drill holes (1,550 metres)
- From-to intervals are measured from the drill collar. All holes were drilled from underground stations.
- All intervals are reported as core length with true width estimated to range from 50-90% of core length.
- 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 the 623, NE-1, NE-1S, and Pierna Mantos. Drilling at Platosa will continue to target areas ahead of production and test the extent of mineralization around mine workings.
Drilling to follow up on the hole EX21UG690, which intersected a wide high-grade interval that has a potential vertical orientation (see press release dated October 5, 2021) is currently underway, with assay results pending.
