EXCELLON REPORTS THIRD QUARTER 2021 FINANCIAL RESULTS

Toronto, Ontario – November 16, 2021 – Excellon Resources Inc. (TSX:EXN, NYSE:EXN and FRA:E4X2) ("Excellon" or the “Company") is pleased to report financial results for the three‐ and nine‐ month periods ended September 30, 2021.

Q3 2021 Financial and Operational Highlights (compared to Q3 2020)

Revenues of $9.2 million (Q3 2020 – $9.9 million)
Gross profit of $1.8 million (Q3 2020 – $2.7 million)
Total cash cost net of byproducts per silver ounce payable improved to $11.02 (Q3 2020 – $12.55)
All‐in sustaining cost (“AISC”) per silver ounce payable increased to $21.52 (Q3 2020 – $19.09),

partially due to increased underground exploration at Platosa following up on the discovery of the 817 Zone, a new, high‐grade and vertical zone of mineralization, with the discovery hole intersecting 2,860 g/t silver equivalent (“AgEq”) over 7.5 metres

Production cost per tonne of $281 per tonne (Q3 2020 – $227 per tonne)
Fifth consecutive quarter of over 21,000 tonnes mined and milled, with sizeable stockpiles of ore

and concentrate at quarter‐end that were processed and/or delivered in early October

Exploration expenditures increased 27% to $2.5 million (Q3 2020 – $2,001), with increased

drilling expenditures at Silver City

Cash and marketable securities of $5.0 million at September 30, 2021 (December 31, 2020 – $10.7

million)

“Platosa continued to generate cash in Q3, which allowed us to realize our highest quarterly exploration expenditure since Q1 2013,” stated Brendan Cahill, President and CEO. “We continue to drill with two rigs at Silver City and aggressively follow‐up on the 817 Zone at Platosa, where we discovered a new, high‐grade and vertical zone of mineralization beneath an area that was mined in 2017. We expect to release new results from 817 shortly.”

“Revenues and costs have remained fairly stable over the past five quarters, though we have seen certain increases for electricity and labour – the latter due to labour law amendments in Mexico that took effect in Q3. Strong base metal prices and strengthening silver prices were beneficial in Q3 and have subsequently increased further. We also had ore in stockpile representing approximately 58,000 AgEq ounces at quarter‐end, which will contribute to Q4 sales.”

“We continue to seek a just resolution regarding the judgment received in Q3 against our subsidiary, San Pedro Resources. As stated previously, we do not expect this judgment to impact any of our other assets, including Platosa, Kilgore, Oakley and Silver City or foresee any significant cash outflow from Excellon or San Pedro. Under accounting rules, however, we were required to take a provision for this litigation, which had a significant non‐cash impact on our financial results. Despite the injustice of this judgment, we remain open to a fair and rational settlement with the plaintiff, while also pursuing avenues through our labour, community and government relationships and investigating remedies under international law. San Pedro continues to operate in the ordinary course.”

(1) Revenues are net of treatment and refining charges (“TC/RCs”). Refer to Note 18 of the Q1 2021 Condensed Consolidated Financial Statements for detail of the comparative period reclassification of foreign exchange differences on provisionally priced sales.

(2) Adjusted net loss excludes $22.3 million related to the Provision for litigation (included in Other expenses), the related $0.8 million impairment loss and $3.1 million deferred tax asset derecognition (included in Income tax expense).

(3) Cash flow from operations before changes in working capital.

(4) Production cost per tonne includes mining and milling costs excluding depletion and amortization.

(5) AISC per silver ounce payable excludes general and administrative and share‐based payment costs attributable to the Company’s non‐producing projects and includes underground drilling costs. The comparatives have been revised to conform with the current allocation.

(6) Average realized price is calculated on current period sale deliveries and does not include the impact of prior period provisional adjustments in the period.

(7) Results for the comparative nine‐month period ended September 30, 2020 were impacted by the suspension of mining operations by the Government of Mexico from April 2^nd to June 1^st, 2020 (the “Suspension”) in response to the COVID‐19 pandemic.

Revenues decreased by $0.7 million (or 7%) during Q3 2021 compared to Q3 2020, driven by a 5% decrease in silver‐equivalent ounces payable and a 3% decrease in the realized silver price, partly offset by 27% and 24% increases in realized lead and zinc prices, respectively. Revenue increased by $12.5 million (or 78%) for the 9‐Mos 2021, reflecting the impact of higher metal prices ($7.5 million) and higher volumes sold ($5.0 million). As discussed above, the Suspension resulted in negligible metal sales and revenue during Q2 2020, which impacted 9‐Mos 2020.

In 9‐Mos 2021, Platosa generated net cash inflow of $6.3 million (9‐Mos 2020 – outflow of $4.0 million) from collected revenue of $30.6 million (9‐Mos 2020 – $15.2 million) net of production costs of $18.5 million (9‐Mos 2020 – $13.7 million) and capital expenditures of $5.8 million (9‐Mos 2020 – $5.5 million).

Cost of sales increased by $0.2 million during Q3 2021, primarily driven by an increase of $0.5 million in depletion and amortization as a result of the amortization of assets commissioned since Q3 2020, and partly offset by a $0.3 million decrease in production costs mainly driven by a variance in the inventory adjustment relating to the build‐up of ore and concentrate inventories at period end. Cost of sales increased by $5.7 million for the nine‐month period ended September 30, 2021 relative to the comparative period, primarily due to the Suspension.

Administrative expense in Q3 2021 were consistent with Q3 2020. Administrative expenses increased by $0.4 million during 9‐Mos 2021 mainly due to higher insurance expense relating to the Company’s NYSE American listing, which was completed in late Q3 2020.

Increased exploration expense in Q3 2021 primarily reflects drilling expenditures at the Silver City Project which increased $0.5 million compared to the comparative period. During 9‐Mos 2020, Exploration programs were limited by the initial outbreak of COVID‐19 globally in 2020 resulting in lower expenditures.

As announced on August 10, 2021, the Company received the formal written decision regarding the litigation involving the Company’s subsidiary, San Pedro Resources (“San Pedro”), in respect of the La Antigua mineral concession (the “Judgment”). The Company recorded a Provision for litigation of $22.2 million in Q3 2021 as required under IFRS’s International Accounting Standard 37 – Provisions, Contingent Liabilities and Contingent Assets (included in Other Expenses). The uncertainty related to the Judgment also contributed the $0.8 million impairment loss and the $3.1 million deferred‐tax asset derecognition (included in income tax expense). Excluding the Provision for litigation, other expense decreased by $0.9 million in Q3 2021, as Q3 2020 included unrealized losses on marketable securities and warrants and unrealized foreign exchange losses that were not significant in Q3 2021. For 9‐Mos 2021 compared to 9‐ Mos 2020, the $0.5 million increase in other expenses before the Provision for litigation mainly reflects changes in the values of marketable securities and warrants, partly offset by a decrease in foreign exchange losses.

Net finance expense in Q3 2021 consists primarily of interest expense on the 5.75% secured convertible debentures (the “Convertible Debentures”) issued in Q3 2020. Net finance expenses for Q3 2020 included a $0.3 million unrealized gain on currency hedges, which have since been settled.

Net finance expense of $2.4 million for 9‐Mos 2021, was $0.6 million higher than 9‐Mos 2020, reflecting interest on the Convertible Debentures ($2.4 million, of which $0.6 million relates to coupon interest and $1.8 million represents the accretion of the face value of the Convertible Debentures), which exceeds prior‐year interest costs of $1.1 million ($0.4 million on Convertible Debentures and $0.7 million interest on the $6 million credit facility with Sprott Private Resource Lending II (Collector), LP), partially offset by a $0.7 million unrealized loss on currency hedges in 2020, which have since been settled at a net realized loss of $40,000.

The Company’s assets in Mexico, including those held in San Pedro, are security for the Convertible Debentures. The Company is monitoring and assessing whether the Judgment and actions taken by the plaintiff to date in connection with enforcing the Judgment could be considered to constitute an event of

default under the trust indenture dated July 30, 2020 governing the outstanding Convertible Debentures (the "Indenture"). While the Company does not consider that an event of default has occurred under the Indenture, the Debenture holders may try to take the position that an event of default has occurred under the Indenture. An event of default under the Indenture, if not cured or waived, could result in the acceleration of all the Company's debt under the Debentures and could materially and adversely affect the Company’s future operations, cash flows, earnings, results of operations, financial condition and the economic viability of its projects. San Pedro has not received any notice that the plaintiff has initiated any insolvency proceedings or any enforcement proceedings that could result in San Pedro losing control of the toll milling operations.

Adjusted net loss increased by $4.5 million in Q3 2021 over Q3 2020, mainly due to lower gross profit (by $1.0 million) and a $3.6 million change in tax expense reflecting the Q3 2021 non‐cash utilization of deferred tax assets ($1.2 million) to offset taxable profits, the derecognition of deferred tax assets as a result of a legal restructuring of subsidiaries in response to changes in Mexican labour laws ($0.3 million), and the $1.8 million non‐cash recovery of deferred taxes in Q3 2020. Exploration and finance expenses increased (by $0.5 million and $0.4 million respectively), while unrealized foreign exchange losses improved by $0.7 million. For 9‐Mos 2021, adjusted net loss increased $0.2 million mainly driven by improved gross profit in 2021, as discussed above, more than offset by increases of $2.8 million in exploration expenses and $2.8 million in tax expense, relative to the comparative period.

Total cash cost per silver ounce payable decreased by 12% for the three‐month period ended September 30, 2021 relative to the comparative period, primarily driven by a 15% or $0.6 million decrease in cash costs net of by‐product credits, reflecting a 29% or $0.7 million reduction in TC/RCs, partly offset by a 3% decrease in silver ounces payable in 2021.

Total cash cost per silver ounce payable decreased by 28% for the 9‐Mos 2021, primarily driven by a 41% increase in silver ounces payable in 2021 as the comparative period was impacted by negligible production in Q2 2020 due to the Suspension.

AISC per silver ounce payable increased by 13% in Q3 2021 relative to Q3 2020 due to the impacts of lower silver ounces payable (4%) and higher all‐in sustaining costs (9%). The $0.5 million increase in all‐in sustaining costs was primarily driven by a $0.6 million increase in sustaining capital expenditure, a $0.3 million increase in sustaining exploration expenditure, and partly offset by total cash costs which decreased by $0.6 million or 15% as discussed above.

AISC per silver ounce payable decreased by 15% for 9‐Mos 2021 relative to 9‐Mos 2020, primarily driven by a 41% increase in silver ounces payable in 2021 as 9‐Mos 2020 was impacted by the negligible production realized in Q2 2020 due to the Suspension.

(2) AgEq ounces established using average realized metal prices during the period indicated, applied to the recovered metal content of the concentrates.

(3) Payable metal is based on the metals delivered and sold during the period, net of payable deductions under the Company’s offtake arrangements, and will therefore differ from produced ounces.

(4) Results for the comparative nine‐month period ended September 30, 2020 were impacted by the Suspension.

Mine performance in Q3 2021 continued to benefit from leadership updates in the superintendencies of geology, technical services and maintenance, which have led to improvements in mine planning, geological interpretation and equipment reliability. Silver grades in Q3 2021 were 9% higher than the comparative period, with lower lead and zinc grades relative to Q3 2020, reflecting variation in the mantos mineralization. Recoveries were lower than Q3 2020 due to lower base metal feed grades and flotation performance. Grind size, reagent additions and cell operating‐parameter modifications took place late in Q3 2021, which improved the recovery performance overall. The modifications are being closely monitored for ongoing sustainability. Metallurgical investigation is being performed on concentrate and feed samples in XPS lab (QUEMSCAN) under the supervision of Excellon’s independent metallurgical consultancy. Ore stockpiles at September 30, 2021 comprised 2,252 tonnes of mineralized material reflecting unprocessed and unsold production of approximately 58,000 AgEq ounces.

COVID‐19 Update

Excellon continues to benefit from robust measures to prevent COVID‐19 among the workforce and local communities and to monitor the effectiveness of these measures in mitigating any potential impact on business activities. The Company’s actions have been successful to date and the pandemic has not had any material impact on production or shipment of concentrate. Vaccination programs are progressing well in Mexico, with 100% and over 94% of the Company’s workforce having received first and second vaccinations, respectively.

About Excellon

Excellon’s vision is to create wealth by realizing strategic opportunities through discipline and innovation for the benefit of our employees, communities, and shareholders. The Company is advancing a precious metals growth pipeline that includes: Platosa, Mexico’s highest‐grade silver mine since production commenced in 2005; Kilgore, a high‐quality advanced exploration gold project in Idaho with strong economics and significant growth and discovery potential; and an option on Silver City, a high‐grade epithermal silver district in Saxony, Germany with 750 years of mining history and no modern exploration. The Company also aims to continue capitalizing on current market conditions by acquiring undervalued projects.
