Toronto, Ontario – July 12, 2018 – Excellon Resources Inc. (TSX:EXN, EXN.WT and EXN.WT.A; OTC:EXLLF) ("Excellon" or the “Company") is pleased to announce second quarter 2018 production results from the Platosa Mine in Durango, Mexico.

Q2 2018 Production (compared to Q2 2017)

• Silver equivalent (“AgEq”) production increased 120% to 637,205 AgEq oz
  (Q2 2017 – 289,566 AgEq oz)
  • Silver production increased 73% to 277,701 oz (Q2 2017 – 160,820 oz)
  • Lead production increased 117% to 1.8 million lb (Q2 2017 – 0.9 million lb)
  • Zinc production increased 152% to 2.8 million lb (Q2 2017 – 1.1 million lb)
• All-in sustaining cost (“AISC”) of less than $10 per payable silver ounce achieved for the quarter

“We realized further improvements at the Platosa Mine and Miguel Auza concentrator during the second quarter, including the most tonnes processed at Miguel Auza since the Company acquired the mill in 2009,” stated Brendan Cahill, President and CEO. “We also achieved AISC of less than $10 per payable silver ounce for the quarter. While there is more work to do to increase production, we’re making strong progress. Most importantly, we now have a stable, cash-flowing operation at Platosa that provides a platform for our greater exploration and growth goals.”

Productions Results

*   Subject to adjustment following settlement with concentrate purchaser.
** AgEq ounces established using average realized metal prices during the period indicated applied to the recovered metal content of concentrates.

Production during Q2 2018 improved as multiple, high-grade ore faces were accessed in the Rodilla, Pierna and 623 mantos. In June, two bolting units were commissioned underground to expedite ground support installation as ground conditions have been and remain, at this point, a primary area of focus to support production increases.

During the quarter, the Company continued to process low-grade historical stockpiles and sump material, with minimal associated mining cost. This mineralized material is blended with mined ore to improve payability and recoveries (particularly for lead and zinc), as well as being cash flow positive.

The Company is finalizing an updated mineral resource estimate and technical report, which has taken longer than originally anticipated. The technical report is an ordinary course update to the last mineral resource estimate as of December 31, 2014. Drilling recommenced at Platosa in mid-2016 and this updated mineral resource estimate will include drilling up to March 31, 2018. As referenced in a press release dated May 31, 2018, the Company identified additional optimizations to the resource model and mine plan, which have now been incorporated.

Mr. Denis Flood, P. Eng., Vice-President Technical Services, has acted as the Qualified Person, as defined in NI 43-101, with respect to the disclosure of the scientific and technical information relating to production results contained in this press release.
