Toronto, Ontario--(Newsfile Corp. - January 10, 2024) - Excellon Resources Inc. (TSX: EXN) (OTCQB: EXNRF) (FSE: E4X2) ("Excellon" or the "Company") is pleased to provide the following "Year in Review" and corporate update, with the intention of providing clarity on key value drivers for 2024.

2023 Year in Review

Summary

• Eliminated the US$22 million litigation liability overhang, through the deconsolidation of San Pedro Resources¹.
• Shareholders approved the restructuring of the Company's 5.75% secured convertible debentures (the "Convertible Debentures")², which restructuring, when completed, is anticipated to reduce indebtedness by 58% or $10.4 million and provide a clearer runway for equity recovery.
• At Kilgore, a positive U.S. District Court ruling³ upheld Excellon's Plan of Operations, supporting Excellon's continued exploration activities in Idaho.
• At Silver City, Excellon recently completed an extension of its Mohorn, Oederan and Frauenstein licenses and drilling operating permits to March 15, 2027.

Shawn Howarth, President and CEO, commented, "While 2023 was challenging on several fronts, Excellon remained resilient. Our transition from silver production in Mexico allows us to now focus on high quality exploration at Kilgore and Silver City. The deconsolidation of wholly owned San Pedro Resources, together with the restructuring of the Convertible Debentures, when completed, is anticipated to remove approximately $40 million in liabilities from Excellon's balance sheet. The proposed restructuring of the Convertible Debentures, which received overwhelming support from shareholders at the Company's Annual and Special Meeting of Shareholders, is expected to close in January."

Mr. Howarth added, "Excellon's renewed strategy is to advance precious metals resource growth in high quality jurisdictions with lower execution risk. We are approaching Kilgore with a revamped exploration plan and, pending sufficient funding, expect to be drilling again later this year. We are excited about the potential with Kilgore, specifically our understanding of high grade mineralized controls in areas of the deposit previously underexplored, or not explored at all. Our revised exploration model suggests there is ample opportunity to expand our existing resources to depth as well as discover new zones below cover along strike for up to five kilometres. We now need to confirm this global potential with the drill bit."

"At Silver City, we are pleased to announce a recent extension of our core licenses allowing Excellon to continue its exploration activities for the next three years on these claims. We believe Silver City has the potential to be a first mover on a new exploration district in Saxony, Germany, and Excellon is well-positioned to capitalize. Our immediate priority is defining a path to realize on Silver City's potential most efficiently, which may include a transaction or spin-out of the asset."

12-Month Outlook and Next Steps

Summary

• Renewed strategy focusing on growing mineralization at Kilgore, through targeted drilling at high priority areas below the existing mineralized envelope and key areas that have not been the subject of high density drilling.
• Evaluate alternatives to enhance value for shareholders in Silver City, through either a spin-out or other corporate transaction.
• Complete the strategic review of prior Mexico operations to allow Excellon to focus energies on key assets.
• Pursue acquisition opportunities where Excellon can unlock further value for shareholders.

The following activities are subject to completing the necessary funding to execute key initiatives over the next 12 months.

Grow: Kilgore Project, Idaho

Excellon believes there is mineralization growth potential that has not been fully tested at Kilgore. Since acquiring the asset in 2020, Excellon completed an extensive relogging of drillholes designed to significantly improve our understanding of the geologic model and exploration thesis.

Originally interpreted as grading ~0.5 g/t Au over large intervals, Kilgore was viewed as more characteristic of other typical widely disseminated, epithermal-style deposits. Through geologic remodeling, Excellon plans to target controls on higher grade mineralization found throughout the deposit, specifically those controls in the deeper permeable Aspen sediments that appear to host higher grade feeder and stockwork structures.

Higher grade feeder structures have also been identified throughout the Kilgore stratigraphy. The following table previously disclosed by Excellon (see press release of the Company dated March 10, 2022), illustrates selected intervals encountered with previous drilling.

3. All intervals are reported as drilled length.

A Renewed Exploration Thesis for Kilgore: Near-Deposit or Resource Mineralization Growth
With most of the historic drilling focused on felsic tuffs, the opportunity for Excellon is to expand on a redeveloped geologic model, focusing on the Aspen sedimentary package. Our interpretation is that the Dacite intrusive acted as a barrier to the transfer of mineralized fluids from the sedimentary package to the tuffs.

Figure 1 illustrates how the dacitic barrier capped mineralized fluid from further precipitation, and therefore, understanding structural controls in the Aspen sediments leads to a better understanding of high-grade emplacement.

When re-inspecting core, mineralization in the Aspen sediments is associated with quartz stockwork, often hosting visible gold. The nuggety effect of coarse gold within the stockwork, and the historic practise of hydraulic core splitting are likely attributing factors to irregular grade distribution within the Aspen sediments. The current exploration model suggests there are likely multiple sub-vertical higher grade structures as yet unplumbed within the Aspen Formation (Figure 1 below).

The Plan: Drilling to Test Thesis
Subject to securing necessary funding, the Company is targeting a Phase I drill program of 5,000 to 7,500 metres. The drilling would target expansion of the mineralized boundary, specifically the sediments and underexplored areas below the existing deposit. While historic drilling focused on widely disseminated zones, the Company's priority will be narrower but higher grade zones of mineralization.

If Phase I drilling is successful, Excellon expects to scale the drill program accordingly in a larger, Phase II program.

Property Wide Exploration Potential: Numerous Targets for Follow-up
In addition to drilling, the Company plans to build on its surface exploration plan, including both near existing mineralization and high-priority, property-wide targets (see Figure 2 below). These targets were generated through previous prospecting and remote sensing campaigns and largely remain underexplored across a vast 4,917 hectare land package. The purpose of the surface prospecting is to generate the next generation of drill-ready targets to prove out the Company's thesis of potential multiple low-sulphidation epithermal deposits along the caldera similar to the current Kilgore deposit.

Launch: Realize Optionality at Silver City Project, Germany
Excellon believes this is an opportune time to be exploring in Europe. What initially attracted the Company to Silver City was a project that was situated in the Erzgebirge (Ore Mountains) region of Germany, the origin of the silver rush in Europe, considered a highly metallogenetic state endowed by numerous silver and base metals deposits, but a region that lacked significant modern exploration.

Excellon's vision for the Silver City Project is exploring for a multi-million ounce silver deposit, targeting 2.5 metre mineralized widths at grades that could support underground economics. To-date, drilling has returned mineralization across an average vein thickness of about 0.2 to 1.0 metres, but the Company believes the potential for greater widths still exists.

To further advance target identification, the project would benefit from a detailed structural geology study identifying potential for wider structural zones, intersections and other controls for mineralization.

Excellon will continue to assess the market for a potential spin-out of Silver City. If structured correctly, a spin-out could be an efficient way to raise capital for exploration, while providing shareholders direct participation in an emerging, "Europe-focused" exploration vehicle with leverage to silver price, currently not encapsulated in Excellon. Management will continue to update as necessary.

Divest: Exit Mexico Operations

Excellon is undergoing a strategic review of its Mexico operations, prioritizing a transaction or divestiture involving Minera Excellon de Mexico, S.A. de C.V., which wholly owns the past-producing Platosa Mine.

The Company will provide further updates as and when available.

Timeline and Next Steps

Predicated on having sufficient capital for execution, the Company anticipates the following timeline for 2024:

• Fundraise / recapitalization of Excellon (Q1 2024)
• Kilgore drill results for 2022 drilling (end Q1 2024)
• Value strategy for Silver City (Q2 2024)
