Toronto, Ontario – June 1, 2020 – Excellon Resources Inc. (TSX:EXN, EXN.WT, OTC:EXLLF and FRA:E4X1) ("Excellon" or the “Company") is pleased to announce that the Mexican Government has officially declared mining an essential business in the Federal Registry and companies can commence the restart of operations beginning on June 1^st provided that they meet established COVID-19 guidelines. At this time, the Company’s Platosa and Miguel Auza operations in Mexico are preparing for a safe restart in the immediate term.

“We are pleased that the Government of Mexico has confirmed mining as an essential service, facilitating the restart of our operations,” stated Brendan Cahill, President and CEO. “Our operations and those of the mining industry throughout Mexico are critical to economic activity in the country and to the well-being of our employees and the communities that rely on our presence. We will continue to implement our protocols and remain vigilant to protect our employees, their families and the wider communities as we restart operations. During the suspension of operations, we have also focused on planning a series of cost-saving and efficiency initiatives, which we will implement as operations resume.”

During the suspension, critical pumping and routine maintenance of critical infrastructure continued at both Platosa and Miguel Auza to ensure a smooth restart of operations. The Company is also reviewing exploration programs to determine a safe restart. The Company has not reported any cases of COVID-19 and there have been minimal cases reported in the surrounding communities.

The Company has progressed several improvement plans that are expected to materially reduce operating costs. Specifically, the Company is finalizing preparations with a new energy provider, has reduced its labour force and is negotiating or implementing a series of other optimization or cost-saving initiatives. The switch in energy providers is expected to result in a significant decrease in unit rates, with energy recently accounting for approximately 40% of operational expenditures.

The Company has been implementing a series of measures to protect its workforce and the local communities over the past two months based on evolving international best practice from the U.S. Centers for Disease Control and the mining industry. The Company is reviewing those measures to ensure that they are fully functional and meet the Mexican Government requirements prior to resuming operations. The Company has provided detailed plans to the Undersecretariat of Mining and the Health Ministry to demonstrate compliance with the prescribed requirements.

The Company’s response to COVID-19 included implementation of the following:

• Routine health checks of all persons entering our business units;
• Procuring the necessary personal protective equipment and other materials necessary for effective COVID-19 response;
• Physical distancing within the workplace;
• Prohibiting entry of visitors and contractors;
• Limiting entry of suppliers to those delivering critical operational materials; and
• Engaging with local communities to raise COVID-19 awareness, encouraging people to remain at home and practice physical distancing and providing locally made cloth masks to the communities of Bermejillo and Miguel Auza.
