TELSON MINING CORPORATION ANNOUNCES GRADUATION TO TIER 1 OF THE TSX VENTURE EXCHANGE

Telson Mining Corp. has been approved for graduation from Tier 2 issuer status to Tier 1 issuer status by the TSX Venture Exchange. Telson will commence trading as a Tier 1 issuer on the TSX Venture Exchange on Tuesday, May 29, 2018. Tier 1 is the premier tier on the TSX Venture Exchange and is reserved for the most advanced issuers with significant financial resources.

Commenting on this news, Ralph Shearing, president of Telson, said: "Telson's graduation to Tier 1 of the TSX Venture Exchange is a further demonstration of the quality of our Campo Morado and Tahuehueto projects and of our management team. Graduating to Tier 1 status will also provide the company with a more favourable regulatory environment, decreased filing requirements and increased opportunity for participation by institutional investors. We would like to thank the TSX Venture Exchange for recognizing Telson's rapid growth over the past couple of years, which was demonstrated by Telson transitioning from an exploration and development company to a producer with the declaration of commercial production at our Campo Morado mine, effective May 15, 2018."
