Excellon Resources Inc. Drills 1,170 g/t Silver Equivalent over 4.2 Metres at Platosa

Highlights

• Further definition and expansion of the NE-1S and Pierna Mantos, with diamond drilling results including:
• • 1,170 g/t silver equivalent ("AgEq") over 4.2 metres (741 g/t Ag, 7.5% Pb, 4.8% Zn and 0.9 g/t Au) in EX20UG485, including 1,812 g/t AgEq over 2.0 metres (1,153 g/t Ag, 12.3% Pb, 6.1% Zn and 1.7 g/t Au); and
  • 1,886 g/t AgEq over 2.4 metres (728 g/t Ag, 21.2% Pb and 17.8% Zn) in EX20UG463, including 2,109 g/t AgEq over 1.9 metres (818 g/t Ag, 24.7% Pb, 19.1% Zn);
• Drilling underway to define and discover new mineralization in an area of the Platosa deposit that was never effectively drilled from surface - the Gap Zone - with 300 metres of potential mineralized strike to be explored.

"Definition and expansion drilling continues to deliver from underground at Platosa," stated Ben Pullinger, Senior Vice President Geology & Corporate Development. "We have two rigs turning underground right now, with a number of targets to follow-up on. A critical target is the "Gap Zone," an area of potential sub-vertical mineralization that was never properly drilled historically from surface and that is open to our developing 10-20 target, 300 metres away. This area represents a significant opportunity to define additional mineralization at Platosa."

Exploration Results

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

Drilling from underground continues to define and expand known mineralization ahead of production at the Pierna, NE-1 and NE-1S Mantos. Most significantly, drilling into the Gap Zone (see Figure 1), a zone of vertical mineralization inadequately tested with vertical holes drilled from surface, provides a significant opportunity to add additional mineralization along a target approximately 300 metres along strike with a vertical extent of 30-40 metres. This target will be 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.

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.

Such statements include, without limitation, statements regarding mineral resources estimates, the future results of operations, performance and achievements of the Company, including potential property acquisitions, the timing, content, cost and results of proposed work programs, the discovery and delineation of mineral deposits/resources/reserves, geological interpretations, proposed production rates, potential mineral recovery processes and rates, business and financing plans, business trends and future operating revenues. 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.
