­­­­­­­­­­­Toronto, Ontario - March 24, 2016 - Excellon Resources Inc. (TSX:EXN; OTC:EXLLF) ('Excellon' or the 'Company'), Mexico's highest grade silver producer, is pleased to report financial results for the three- and twelve-month periods ended December 31, 2015.

2015 Financial, Operational and Corporate Highlights

• Revenue of $16.2 million (2014 - $30.8 million)
• Sales of 1.3 million silver equivalent ounce ('AgEq oz') payable (2014 - 1.9 million AgEq oz payable)
• Mine operating loss of $2.5 million (2014 - earnings of $2.4 million)
• Adjusted net loss of $4.4 million or $0.08/share (2014 - adjusted net loss of $3.8 million or $0.07/share)
• Optimization plan developed and commenced during 2015 to comprehensively dewater Platosa over the course of 2016, with financing for the program arranged in Q4 2015
• Production cost per tonne reduced by 28% relative to 2014
• Corporate G&A reduced by 23% relative to 2014 and at the lowest levels since production at Platosa commenced in 2005
• Arranged the sale of non-core DeSantis Property for 850,000 shares of Oban Mining Corporation
• Completed development of initial access to Rodilla Manto in late 2015/early 2016, with production commencing seven months ahead of schedule, in large part due to drier mining conditions
• Cash, marketable securities and current account receivable totaled $4.7 million
  at December 31, 2014 (December 31, 2014 - $5.2 million)
• Net working capital totaled $5.5 million at December 31, 2015 (December 31, 2014 - $6.2 million)

'During 2015, we laid the groundwork for a return to high grade and low cost production at Platosa,' stated Brendan Cahill, President and Chief Executive Officer. 'Despite challenging commodity and equity markets and operating conditions, we enhanced our board and management team, developed a plan to comprehensively solve Platosa's water issues and arranged the financing to commence this optimization program. Operating costs per tonne were reduced by almost 30% from 2014, even while mining less tonnage in 2015, and corporate G&A was reduced below 2005 pre-production levels. Additionally, we continued to see the benefits of long term dewatering efforts at Platosa, with 2015 development supporting access to the Rodilla Manto in late February 2016, seven months ahead of schedule. With access to Rodilla and the optimization program underway, we expect to see improving rates of production and ore grades through the course of this year.'

Financial results for the three and twelve-month periods ended December 31, 2015 and 2014 are as follows:

1. Revenues are net of treatment and refining charges.
2. Adjusted net loss for 2014 reflects results before $15.5 million impairment charge on exploration properties in Canada.
3. Adjusted net loss for Q4 2015 and 2015 reflects results before $0.7 million impairment charge on DeSantis exploration property in Canada.
4. Cash flow from operations before changes in working capital.

Production from Platosa was below the Company's original forecast as water management limited planned access to the Rodilla, 623 and Guadalupe South mantos and implementation of the optimization plan commenced later in the year than originally planned due to equity and credit market conditions. Production for the year was primarily from the 6A Manto, remnants of the Guadalupe Manto and the peripheries of the 623 and Guadalupe South Mantos, with production from the latter two mantos being most impeded by water management during the year. Particularly, in November and December 2015, ore was primarily produced from remnant areas of the Guadalupe North Manto, accounting for the relatively lower grades. Tonnages mined and milled of 13,145 tonnes and 12,999 tonnes in Q4 2015 reflected a 22% increase and 11% increase, respectively, compared to Q4 2014. For 2015, tonnes mined and milled of 54,485 tonnes and 56,849 tonnes represented 15% and 11% decreases, respectively, compared to 2014.

Production costs in 2015 decreased by $8.9 million or 36%, relative to costs in 2014 despite 15% fewer tonnes mined during the year, a result of improved maintenance practices on pumps and mobile equipment.

The Company recorded a net loss of $1.7 million for Q4 2015 compared to a net loss of $2.6 million in Q4 2014. The Company's adjusted net loss of $1.0 million in Q4 2015 reflects the current period's results before recording an impairment of $0.7 million on the DeSantis exploration property in Canada, the sale of which was arranged with Oban Mining Corporation and is expected to close in the coming weeks following receipt of ordinary course mining lease transfer consents. The Company recorded an adjusted net loss of $4.4 million in 2015 compared to an adjusted net loss of $3.8 million in 2014.

During Q4 2015, the Company generated lower net revenues of $2.5 million compared to $4.2 million in Q4 2014, primarily due to lower silver, lead and zinc production and lower metal prices. Overall, in 2015, the Company's revenues were impacted by both metal production and prices. In 2015, the Company produced 1.3 million silver equivalent ounces payable compared to 1.9 million silver equivalent ounces payable in 2014; while silver prices averaged less than $16/oz in 2015 compared to $19/oz in 2014. In Q4 2015, the Company recorded income of $0.8 million comprising foreign exchange gains of $0.4 million and royalty income of $0.7 million, offsetting $0.4 million in financing costs primarily related to embedded derivative fair value adjustments, compared to a foreign exchange loss of $0.7 million and realized loss of $0.3 million on a sale of marketable securities in Q4 2014.

Cash corporate administrative expenses in Q4 2015 were comparable to Q4 2014 despite transactional costs incurred in Q4 2015 in respect of a convertible debenture and royalty financing, reflecting continued cost discipline at the corporate head office in Toronto during both periods. Cash general administrative expenses of $3.3 million in 2015 improved by 23% compared to 2014 and represented the Company's lowest G&A expenditures on an annual basis since production commenced at Platosa in 2005.

Exploration expenses incurred during the period were $0.1 million in Q4 2015 compared to $0.3 million in Q4 2014 and $0.7 million in 2015 compared to $2.1 million in 2014. Exploration during the quarter and the year was limited in an effort to conserve funds in the current silver price environment. Planningfor additional drilling continues as significant potential remains for further new manto discoveries as the deposit area is open to the north, northeast, east and southeast of the known mantos.

The Company invested $0.9 million during Q4 2015 in capital expenditures for mine development compared to $1.4 million in Q4 2014. In 2015, the Company invested $1.6 million in capital expenditures, compared to $3.3 million in 2014. Mine development continues to be a priority for 2016 as the Company accesses the Rodilla and high-grade 623 mantos, the latter of which hosts mineral resources of 83,000 tonnes at 1,232 g/t Ag (1,777 g/t AgEq).

Total cash cost per silver ounce payable was $19.86/oz in Q4 2015 compared to $24.40 in Q4 2014. In both quarters, water management limited access to mineable ore, increasing costs on a per ounce basis. The Company's total cash cost in 2015 was $15.11, compared to $13.76 in 2014. AISC was $34.92 during Q4 2015 compared to $38.67 in Q4 2014, the result of significantly reduced silver ounces payable in both periods. AISC for 2015 of $22.55 was comparable to $21.69 in 2014.

Excellon defines AISC per silver ounce as the sum of total cash costs (including treatment charges and net of byproduct 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.

Optimization Plan

As announced on June 2, 2015 and November 2, 2015 and summarized in the National Instrument 43-101 technical report on the Platosa Property dated July 9, 2015, the Company has developed an optimization program to comprehensively manage water at Platosa in the future through an enhanced pumping system. The first phase of the optimization plan is ongoing.

The Company expects the optimization plan to be fully implemented during the latter half of 2016, but expects to see incremental benefits during the implementation period. In recent weeks, development has focused on a pumping gallery for the first set of eight (est.) dewatering wells, with drilling of the first well expected to commence in the coming days. Pilot well testing near the 623 Manto is ongoing and will be used to target locations for the second set of six (est.) dewatering wells to be drilled later in the year. Further updates on the progress of this program will be provided regularly during the implementation period.

Production Highlights

Mine production for the three and twelve months periods ended December 31, 2015 and 2014 was as follows:

1. Period deliveries remain subject to assay and price adjustments on final settlement with concentrate purchaser.

Data has been adjusted to reflect final assay and price adjustments for prior period deliveries settled during the period.

1. Silver equivalent ounces established using average metal prices during the period indicated applied to the recovered metal content of the concentrates.
2. Payable metal is based on the metals shipped and sold during the period and may differ from production due to these reasons.
3. Average realized silver price is calculated on current period sale deliveries and does not include the impact of prior period provisional adjustments in the period.

Production of 1.4 million AgEq oz from Platosa was below the Company's original forecasts as water management limited planned access to the Rodilla, 623 and Guadalupe South mantos and implementation of the optimization plan commenced later in the year than originally planned due to financing market conditions. Consequently, mine sequencing proved a challenge during the year and resulted in production from lower grade remnant areas of the Guadalupe South Manto, particularly in Q4.

Production Update

In recent months, water levels in the 6A, Guadalupe North and the Rodilla mantos have reduced significantly, with those areas now requiring minimal pumping. Consequently, the overall pumping rate of the dewatering system was relatively reduced during Q4 (along with the drawdown rate) as the operation began reconfiguring the pumping system to focus on the 623 and Guadalupe South Mantos, which remain below the water table. This process is ongoing, but is expected to be completed in the coming days, which will augment the mine's overall dewatering during the implementation phase of the optimization plan.

In late February 2016, mine operations began accessing ore from the Rodilla Manto, approximately seven months ahead of schedule and at shallower depths than delineated in the block model. The Rodilla Manto was significantly below the water table until recently, but mining conditions are now almost entirely dry in this area, though the lower parts of the manto remain below the water table. The Company is revising mine planning for this manto to accelerate production through the remainder of 2016 and expects to provide a production forecast in due course when these revisions are completed. Additionally, as the Optimization Plan is expected to have a material impact on production at Platosa, the Company expects to adjust production forecasts throughout the year as the Optimization Plan is implemented and begins to improve mining conditions.
