• Adjusted all-in sustaining cost per Ag oz payable ("AISC") reduced by 66% to $11.62 (Q3 2016 - $33.92), excluding the one-time sustaining capital expenditures associated with the Optimization Plan, with no adjustment in the current quarter
• Adjusted net loss of $0.4 million or $0.00/share (Q3 2016 - adjusted net loss of $1.0 million or $0.01/share), excluding non-cash financing loss associated with outstanding convertible debentures (the "Debentures") issued in November 2015

• Appointment of Jacques McMullen, P.Eng. to the Board of Directors, with the retirement of Ned Goodman, and appointment of Nisha Hasan to Vice President Investor Relations

"The third quarter marked a turning point for La Platosa as we resumed generating cash flow and slashed all-in sustaining costs and mining cost per tonne," stated Brendan Cahill, President and Chief Executive Officer. "We began amortizing the costs of the Optimization Plan completed in the second quarter resulting in increased depreciation expense, which has no impact on cash flow, but would otherwise have generated an adjusted net profit. With AISC below $12 at mining rates of 200 tonnes per day, we look forward to further improving results as we increase tonnage going into 2018. With our recently announced financing closing next week, we will also have a greatly improved balance sheet to pursue our exploration plans at Platosa and Miguel Auza."

Financial Results

Financial results for the three and nine-month periods ended September 30, 2017 and 2016 as follows:

During Q3 2017, net revenues increased by 77% to $7.1 million (Q3 2016 - $4.0 million) due to a 95% increase in AgEq payable ounces produced of 443,921 oz compared to 228,172 oz in Q3 2016. A lower realized silver price of $17.06 compared to $19.52 in Q3 2016 was offset by improved treatment and refining charges ("TC/RC") under the 2017 offtake sales agreements.

Cost of sales, including depletion and amortization, increased by 36% compared to Q3 2016. The primary contributors to increased cost of sales were (i) depletion and amortization relating to the amortization of capital costs associated with the Optimization Plan and (ii) increased tonnage. Increased pumping rates associated with the Optimization Plan and an increase in electricity prices from $0.06/kwh to $0.08/kwh also resulted in nominal increases in electrical expense, though pumping efficiency increased by 36%. Due to pumping requirements, electrical consumption will continue to be a key driver of mining costs at Platosa. The Company is currently applying to become a "qualified user" under the recent energy reforms in Mexico, which will allow access to the private market for electricity and competitive unit costs per kWh.

Production costs improved significantly in the quarter to $208/tonne (Q3 2016 - $298/tonne), due to a 66% increase in tonnes milled, lower maintenance costs, the elimination of grouting activities and more efficient electrical utilization.

The Company recorded a net loss of $5.9 million in Q3 2017 (Q3 2016 - net loss of $7.0 million). The Company's adjusted net loss of $0.4 million in Q3 2017 reflects the period's results before recording a $5.6 million fair value adjustment loss (Q3 2016 - $6.0 million loss) on embedded derivative and warrants relating to the Debentures in accordance with IFRS as the Company's stock price increased from C$1.42 to C$2.03 (Q3 2016 - an increase from C$1.23 to C$1.88). Further contributors to the adjusted net loss included: (i) 172% increase in depletion and amortization as monthly amortization of capitalized costs of the Optimization Plan commenced during the quarter, and will continue to be amortized over the life of mine, (ii) 16% increase in cash cost of sales due to higher tonnage milled and (iii) increased exploration costs as drilling resumed at Platosa.

The Company spent $0.4 million on exploration in Q3 2017 (Q3 2016 - $0.2 million) as it continued the drilling programs at Platosa, with 732 metres drilled from underground.

Cash costs net of byproducts per silver ounce payable (or Total Cash Costs) of $2.46 significantly improved from $17.95 in Q3 2016, due to the increase in metal sold during the quarter following successful completion of the Optimization Plan in early July.

The Company's AISC per silver ounce payable of $11.62 (Q3 2016 - $40.85 and adjusted AISC of $33.92) in Q3 2017 resulted from higher tonnage and metal produced with the successful completion of the Optimization Plan. As the Optimization Plan is now complete, the Company has eliminated the "Adjusted AISC" metric in Q3 2017, which excludes one-time costs related to the Optimization Plan, but continues to report it for previous periods for comparative purposes. AISC is expected to continue to decrease as drier mining conditions are expected to allow for increased production at lower costs in the fourth quarter and going forward.

Excellon defines AISC per silver ounce as the sum of total cash costs (including treatment charges and net of by-product credits), capital expenditures that are sustaining in nature, corporate general and administrative costs (including non-cash share-based compensation), capitalized and expensed exploration that is sustaining in nature, and (non-cash) environmental reclamation costs, all divided by the total payable silver ounces sold during the period to arrive at a per ounce figure.

All financial information is prepared in accordance with IFRS, and all dollar amounts are expressed in U.S. dollars unless otherwise specified. The information in this news release should be read in conjunction with the Company's unaudited condensed interim financial statements for the three and nine months ended September 30, 2017 and associated management discussion and analysis ("MD&A") which are available from the Company's website at www.excellonresources.com and under the Company's profile on SEDAR at www.sedar.com.

The Company presents these measures to provide additional information regarding the Company's financial results and performance. Please refer to the Company's MD&A for the three and nine month periods ended September 30, 2017, for a reconciliation of these measures to reported IFRS results.

Production Highlights

Mine production for the periods indicated below were as follows:

The Company completed the Optimization Plan in early Q2 2017 to comprehensively manage water at Platosa through an enhanced pumping system. Mining conditions began to improve materially in mid-May and particularly by late June as dry mining conditions were achieved allowing increased access to high-grade ore.

Development rates increased significantly during the quarter with 269 metres of ore development (an 84% increase over Q2 2017 - 146 metres) and 292 metres of waste development (a 39% increase over Q2 2017 - 210 metres). Development rates are expected to continue to increase going forward.

Production during July was particularly strong in Q3 2017, with a weaker August as increased development was necessary to set up a strong September. A primary ongoing goal of the operation is to ensure development is advanced expeditiously to enable consistent month-to-month production, which should improve quarterly production and financial results going forward.

The Company is currently producing from multiple headings on the Rodilla Manto, Pierna Manto and the connection between the Guadalupe South and 623 mantos. Development is currently driving towards the next levels of the Rodilla, Pierna, Guadalupe South and 623 mantos, all of which are expected to yield production during Q4 2017.
