Toronto, Ontario – August 6, 2019 – Excellon Resources Inc. (TSX:EXN) ("Excellon" or the “Company") is pleased to announce that it has entered into an agreement with Cormark Securities Inc. ("Cormark") as sole bookrunner and lead underwriter, on its own behalf and on behalf of a syndicate of underwriters, pursuant to which the Underwriters have agreed to purchase, on a bought deal basis, 9,500,000 units of the Company (the "Units") at a price of $1.06 per Unit for gross proceeds to the Company of approximately $10 million (the "Offering"). Each Unit will consist of one common share in the capital of the Company (each a “Common Share”) and one-half of one common share purchase warrant (each whole warrant, a “Warrant”). Each Warrant shall entitle the holder to acquire an additional Common Share at a price of $1.40 for a period of 24 months following the closing of the Offering.

The Company has agreed to grant the Underwriters an over-allotment option (the "Over-Allotment Option") to increase the size of the Offering by up to an additional 15%, such option being exercisable in whole or in part at any time prior to the date that is 30 days after the closing of the Offering, to cover over-allotments, if any, and for market stabilization purposes. In the event that the Over-Allotment Option is exercised in full, the aggregate gross proceeds of the Offering to Excellon will be approximately $11.5 million.

The Company intends to use the net proceeds of the Offering to fund exploration and capital expenditures at the Company’s Platosa Project in Durango, Mexico and Evolución Property in Zacatecas, Mexico, for corporate development and for general corporate purposes.

The Units will be offered by way of short form prospectus in each of the provinces of Canada, except Québec, pursuant to National Instrument 44-101 – Short Form Prospectus Distributions. The Units will not be offered or sold in the United States except under Rule 144A or Regulation D or in such other manner as to not require registration under the United States Securities Act of 1933, as amended.

The Offering is scheduled to close on or before August 27, 2019 and is subject to certain conditions including, but not limited to, receipt of all regulatory approvals, including the approval of the Toronto Stock Exchange and the applicable securities regulatory authorities.

The securities offered in the Offering have not been, and will not be, registered under the U.S. Securities Act or any U.S. state securities laws, and may not be offered or sold in the United States or to, or for the account or benefit of, United States persons absent registration or any applicable exemption from the registration requirements of the U.S. Securities Act and applicable U.S. state securities laws. This press release shall not constitute an offer to sell or the solicitation of an offer to buy securities in the United States, nor will there be any sale of these securities in any jurisdiction in which such offer, solicitation or sale would be unlawful.
