(TSXV: TOM) (FSE: 5D5 ) (" Trinity One " or the " Company ") is pleased to provide an operations update on the Silver-1 Mine in Ecuador and Victory Project in Mongolia. The Company is advancing Silver-1 through a multi stream technical program focused on systematic tailings sampling, waste rock evaluation and geophysical planning to generate priority diamond drill targets. In Mongolia, the Company has recently completed a three hole diamond drilling campaign at the Victory Project for a total of approximately 600 metres, with assay results pending.

Highlights Initial samples of tailings from Silver-1 returned 132.82 g/t silver and 0.58 g/t gold, and 118.47 g/t silver and 0.50 g/t gold. Initial waste rock sampling from the historic Silver-1 Mine area returned results including 405.27 g/t silver and 3.07 g/t gold.

"The Company is moving beyond initial sampling toward a systematic 15 metre by 15 metre tailings program designed to test the grade, thickness and continuity of the material across the tailings area. This work will give us a much clearer understanding of the scal
