Excellon Resources Inc. announced results from underground expansion and exploration drilling at the Platosa Mine in Durango, Mexico. Further definition and expansion of the Guadalupe North, 623, NE1 and NE1S 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 historicallymined Guadalupe North Manto. Drilling from underground continues to define and expand known mineralization ahead of production at Guadalupe North, 623, NE1, and NE1S Mantos. Most significantly, the Gap Zone, 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 3040 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 1020 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.
