TriMetals Mining Inc. Restarts Drilling at Gold Springs With Jumbo Target as the Immediate Focus

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Sept. 30, 2015) - TriMetals Mining Inc. (TSX:TMI)(TSX:TMI.B)(OTCQX:TMIAF)(OTCQX:TMIBF), (the "Company"), is pleased to announce that it has contracted a drilling company to start drilling at the Gold Springs project located in mining friendly Nevada and Utah, on October 1, 2015.

The immediate focus of the drilling will be to expand the mineralized zone around the very successful 2014 RC hole J-14-018 which intercepted 138.7 metres at 1.01 g/t gold equivalent* (AuEq), including 36.6 metres at 2.06 g/t AuEq (PR Nov. 12, 2014). This intercept ended in mineralization and tested a deeper portion of the system suggesting that there may be increasing grades with depth.

Ralph Fitch, President and CEO stated "We are very excited to start the new drill program in light of what we have learned from the 2014 drilling and our recently updated PEA. We believe there is an excellent opportunity to continue to expand the Jumbo zone which is open to the North, South and to depth. It's always good to remember that we have a positive PEA and have drilled less than 10% of what we believe is the gold target on the property. In fact we are still drilling the first two of twenty six areas of outcropping gold mineralization."

Jumbo drill targets will include the extension of known mineralization plus the testing of a potential new parallel zone just to the East of the main resource block as well as probing in the far south of the Jumbo zone following the high resistivity anomaly which has correlated with gold mineralization in the zone to the North.

The drilling will start on October 1^st and will consist of approximately 3,700 metres and should take several months to complete.
