EXCELLON ANNOUNCES Q1 PRODUCTION RESULTS

Toronto, Ontario – April 15, 2021 – Excellon Resources Inc. (TSX:EXN, EXN.WT; NYSE:EXN, and FRA:E4X2) (“Excellon” or the “Company”) is pleased to announce Q1 2021 production results from the Platosa Mine in Durango, Mexico.

Q1 2021 Production (compared to Q1 2020)

● Silver equivalent (“AgEq”) production of 516,715 oz (Q1 2020 – 523,742 AgEq oz), including:

o Silver production increase of 11% to 328,747 oz (Q1 2020 – 296,281 oz)

o Lead production increase of 11% to 2.1 million lb (Q1 2020 – 1.9 million lb)

o Zinc production increase of 13% to 2.4 million lb (Q1 2020 – 2.1 million lb)

“We continue to see improved production from Platosa after the changes we made in mid-2020, with our third consecutive quarter of more than 21,000 tonnes mined,” stated Brendan Cahill, President & CEO. “The mine is reaching a good steady state of production, though we continue to see opportunities to improve mill recoveries.”

1.	Subject to adjustment following settlement with concentrate purchaser.
2.	AgEq ounces established using average realized metal prices during the period indicated applied to the recovered metal content of concentrates. AgEq ounces produced during Q1 2021 were lower than Q1 2020 as silver prices increased significantly more than base metal prices, resulting in base metal production contributing less to silver equivalency.

Production in Q1 2021 improved relative to Q1 2020 as the changes and enhancements made in mid-2020 continued to be refined, including modified shift schedules, mining methods and improved water pumping and mine infrastructure efficiency.

Head grades and recoveries in Q1 2021 were consistent with Q1 2020, though lower than Q3 and Q4 2021. Plant improvements during the quarter included rebuilt flotation cells, drying filters, shift schedule modifications and training and management of floor operations, which have begun to stabilize and improve zinc recovery. Improved maintenance practices enabled sustained high throughput with increased plant reliability.

The Company expects to file Q1 2021 financial results after market closing on May 13, 2021.

This press release contains forward-looking statements within the meaning of Section 27A of the Securities Act and Section 27E of the Exchange Act. 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.
