Excellon Resources Inc. Announces Q2 2022 Production Results

Q2 2022 Production (compared to Q2 2021)

• Silver-equivalent ("AgEq") production of 545,444 oz (Q2 2021 - 487,009 AgEq oz), including:
• Silver production of 307,494 oz (Q2 2021 - 296,013 oz)
• Lead production of 1.6 million lb (Q2 2021 - 1.9 million lb)
• Zinc production of 2.1 million lb (Q2 2021 - 2.5 million lb)

"We realized a solid quarter of production from Platosa in Q2," stated Brendan Cahill, President and Chief Executive Officer. "As we reach the final stages of mining from Platosa, we see greater variability in ore produced, which affects grades and recoveries to some extent. We are continuing to mine at a consistent rate, though still foresee the wind-down of operations in the current quarter, with preparations well underway. Meanwhile, we are preparing for the commencement of our drill program at Kilgore and continue to actively pursue acquisition opportunities for producing and development stage assets in Mexico."

Production Results

Consistent throughput resumed in Q2 following the Labour Action at Platosa in March 2022. Production in Q2 2022 was 23,550 tonnes, 9% higher than Q2 2021.

Grades in Q2 2022 were lower than the comparative period due to the limited number of stopes available for production. Feed material primarily came from pillars and remnant zones with lower or variable grades, and higher dilution in the mined mantos.

In Q2 2022, recoveries for lead were lower than the comparative period driven primarily by a 5% higher lead-oxide ratio in Q2 2022, which contributes to lower lead recoveries in the flotation circuit. Zinc and silver recoveries were 7% and 3% higher in Q2 2022, respectively, following the rebuild of the flotation cells and modifications to reagent schemes in mid-2021.

Variances in feed grades and recoveries were primarily due to higher pillar recovery relative to stoping, which offered fewer blending opportunities.

Silver production increased due to higher recoveries in Q2 2022, while lead and zinc production decreased, mainly driven by lower feed grades and high lead-oxide ratios affecting recovery.

As previously disclosed, the Company expects to wind down operations at Platosa during Q3 2022.

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.
