TAHUEHUETO UNDERGROUND DEVELOPMENT RETURNS SIGNIFICANT ASSAY RESULTS FROM EL CRESTON ZONE

Telson Mining Corp. has provided significant assay results from underground development on the El Creston zone at its Tahuehueto mine development and construction project in Durango state, Mexico.

Highlights

Tahuehueto underground development within the El Creston zone has returned significant grades over appreciable widths. Channel sampling results received to date are presented in the attached table. Additional channel sampling has been collected within the El Creston zone from mineralization exposed during underground development and results will be disclosed when assay results are received by the company.

The results in the attached table are the weighted average of a series of samples, generally no more that one metre in width, collected from a continuous channel sample across the mineralized structure.

Antonio Berlanga, chief executive officer, states: "These El Creston samples continue to demonstrate the quality of Tahuehueto mineralization and are, in the case of these El Creston samples, verifying our reserve base established from previous drilling. In the case of the El Perdido underground development, which has extended past the limits of previous drilling, channel sampling results (as released Feb. 22, 2019) are verifying the continuity of mineralization along the El Perdido structure, helping to verify management's assumption that the El Perdido zone connects with the Santiago zone on the same structure and, if continuously mineralized will allow, new exploration along approximately 800 metres of unexplored structure to hopefully add additional resources to the project. Meanwhile, underground development and mill construction preparing the mine for our future on-site production continues as recent photos available on our website demonstrate."

All the samples in the table were submitted to SGS De Mexico SA de CV's independent laboratory located in Durango City, Mexico. Assay methods utilized were GE_FAA313 and GE_ICP14B for gold and silver, respectively, with overlimits followed up with GO_FAG303, multielement GE_ICP14B for lead and zinc with overlimits assayed with GO_ICP90Q. Additional detail on assay methodology used can be found on SGS's website.
