TriMetals Mining Inc. Announces the Start of the 2017 Gold Springs Drill Program

VANCOUVER, BC--(Marketwired - June 20, 2017) - TriMetals Mining Inc. (TSX: TMI) (OTCQX: TMIAF),(the "Company"), is pleased to announce the start of the drill program at the advanced exploration stage Gold Springs gold-silver project in safe, mining friendly Utah and Nevada.

The phase 1 drill program of approximately 30 holes will start with the initial drill holes located in the South Jumbo (historic Etna mine) area where 2016 holes intersected substantial thicknesses and grades, including E-16-005 which intersected 150 metres of 0.87 g/t gold (1 g/t gold equivalent) and ended in the mineral system.

The March 29, 2017 Technical Report and Resource Estimate for the Gold Springs project (PR 17-05 of March 29, 2017) reported an initial resource for the South Jumbo target which is open to expansion along strike in a north-south direction and to depth. The width of the mineralization is still open to expansion as well, as holes were collared in, and bottomed in mineralization. This year's drilling will look to define the width of the mineralization and expand the resource along strike and to depth.

Drilling will then move approximately 700 metres northeast to the Central Jumbo target area (State Section) to fill in the 1.5 km undrilled gap between the South Jumbo and North Jumbo resource areas.

Ralph Fitch, President and CEO, stated, "This phase 1 drill program, part of the planned much larger 125-hole program, will be very exciting as it explores these substantial geological/structural and geophysical targets that have already yielded some of our best results. As this year's program progresses we plan to drill several of our other high priority ZTEM and structural targets.

"TMI has conducted resource drilling on four targets and has developed resources on all four. We believe this year's drill program will continue to demonstrate the tremendous upside potential for the project."
