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.

Highlights

● 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.”

Exploration Results

The following table shows highlighted intervals from the current definition and infill program being conducted from underground at Platosa.

(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.

Platosa drill core samples are prepared and assayed by SGS Minerals Services in Durango, Mexico. The lab is accredited to ISO/IEC 17025. The Company has a comprehensive QA/QC program, supervised by an independent Qualified Person.

Although the Company believes that such statements are reasonable, it can give no assurance that such expectations will prove to be correct. Forward-looking statements are typically identified by words such as: believe, expect, anticipate, intend, estimate, postulate and similar expressions, or are those, which, by their nature, refer to future events. The Company cautions investors that any forward-looking statements by the Company are not guarantees of future results or performance, and that actual results may differ materially from those in forward looking statements as a result of various factors, including, but not limited to, variations in the nature, quality and quantity of any mineral deposits that may be located, significant downward variations in the market price of any minerals produced, the Company’s inability to obtain any necessary permits, consents or authorizations required for its activities, to produce minerals from its properties successfully or profitably, to continue its projected growth, to raise the necessary capital or to be fully able to implement its business strategies.

Cautionary Note to U.S. Investors: The terms “mineral resource,” “measured mineral resource,” “indicated mineral resource” and “inferred mineral resource,” as used on Excellon’s website and in its press releases are Canadian mining terms that are defined in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”). These Canadian terms are not defined terms under United States Securities and Exchange Commission (“SEC”) Industry Guide 7 and are normally not permitted to be used in reports and registration statements filed with the SEC by U.S. registered companies. The SEC permits U.S. companies, in their filings with the SEC, to disclose only those mineral deposits that a company can economically and legally extract or produce. Accordingly, note that information describing the Company’s “mineral resources” is not directly comparable to information made public by U.S. companies subject to reporting requirements under U.S. securities laws. U.S. investors are urged to consider closely the disclosure in the Company’s Form 40-F which may be secured from the Company, or online at http://www.sec.gov/edgar.shtml.
