Toronto, Ontario – April 19, 2018 – Excellon Resources Inc. (TSX:EXN, EXN.WT and EXN.WT.A; OTC:EXLLF) ("Excellon" or the “Company") is pleased to announce first quarter 2018 production results from the Platosa Mine in Durango, Mexico.

Highlights

• Q1 2018 Production (compared to Q1 2017)
  • Silver equivalent (“AgEq”) production more than doubled to 482,079 AgEq oz
    (Q1 2017 – 205,314 AgEq oz)
  • Silver production increased 80% to 194,462 oz (Q1 2017 – 108,118 oz)
  • Lead production increased 109% to 1.3 million lb (Q1 2017 – 0.6 million lb)
  • Zinc production increased 158% to 2.3 million lb (Q1 2017 – 0.9 million lb)
• C$0.65 warrants exercised in early April for proceeds of C$2.17 million

“We worked through challenges early in the quarter and had an excellent finish, exceeding our previously indicated projections,” stated Brendan Cahill, President and Chief Executive Officer. “During the quarter, we completed development to advance production into the next levels of the Pierna, Rodilla and 623 mantos. We are now realizing higher grades and have ample dry inventory to deliver improved production going forward. We also continue to mill lower-grade historical stockpiles, which lower our overall head grade, but deliver good cash flow.”

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 Q1 2018 accessed the Rodilla, Guadalupe South, Pierna and 623 mantos. Production improved during the latter half of Q1 2018, particularly in March, as high-grade ore faces were accessed in Pierna and ground support installation allowed access to high-grade ore in 623. The Company has procured two bolting units to further improve productivity of ground support installation. Both units will be delivered during Q2. More efficient installation of ground support is a key ongoing initiative at Platosa, as the mine continues ramping up to targeted production rates.

The Company also focused on driving ramp development to access the next production levels utilizing the 730 ramp in Pierna and Rodilla and the 725 ramp in 623.  Development rates improved compared to the previous quarter with 178 metres in ore (18% increase over Q4 2017 – 151 metres) and 261 metres in waste (15% increase over Q4 2017 – 227 metres). Development rates are expected to continue to increase as headings drive into the next levels of the mantos. With necessary development now completed, the Company has sufficient dry mineral inventory to advance production in Q2 and into Q3 using a more productive cut-and-fill mining method in Pierna, Rodilla and 623.

Pumping rates also improved as Phase 2 of the Optimization Plan commenced with two wells commissioned at the end of Q1. During Q2, the Company expects to commission two additional wells.

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 following table sets out the mix of ore and low grade stockpiles processed in the first quarter:

* AgEq ounces established using average realized metal prices during the period indicated applied to the recovered metal content of concentrates. 

Ore grades (excluding low-grade stockpiles) averaged 441 g/t Ag, 4.78% Pb and 8.24% Zn during Q1 2018.  At the end of Q1, the Company had 1,535 tonnes of ore in stockpile to be milled early in Q2 2018.

The Company expects to publish an updated mineral resource estimate and technical report in the coming weeks, along with an associated production outlook for the remainder of 2018. The Company expects to release first quarter and annual financial results at market close on May 10, 2018.
