VANCOUVER, BC–(Marketwired – January 27, 2016) – TriMetals Mining Inc. (TSX: TMI) (TSX: TMI.B) (OTCQX: TMIAF) (OTCQX: TMIBF) (the “Company”), is pleased to announce that it has been awarded a 64.75 hectare (160 acres) Utah State mineral lease which covers the historic Etna Mine in the competitive lease offerings just completed by the State of Utah, School and Institutional Trust Lands Administration (SITLA). With this acquisition TMI now controls the entire 8-kilometre Jumbo Trend. This final piece of the Jumbo Trend encompasses the historic workings of the Etna mine which was a significant underground producer in the district. Historic records ⁽¹⁾ indicate that the Etna workings extended to a depth of 53 metres (175 feet) with production occurring along the north-south trending vein for some 80 metres.

Ralph Fitch President and CEO, stated, “The importance of this acquisition is that it provides the Company with yet another high-priority target for developing additional resources on our Gold Springs project. The Etna Mine was the last piece of property we needed to completely control the full 8 kilometres of the Jumbo trend. Etna is part of the same strong ZTEM geophysical anomaly that extends south from the Jumbo Target where it was used successfully to guide resource drilling. With this acquisition the Etna target immediately adds 800 metres of strike of the potential gold zone and becomes a high priority target for future resource drilling.”

The Company has conducted a limited amount of drilling to the immediate south of these acquired lands. Hole E-12-001 is located immediately adjacent to these SITLA lands and contains the best drill intercept in the Etna area (High Desert Gold Corp. Press Release 12-13, August 2, 2012).

* Gold Equivalent (AuEq) calculated using a 61.9 gold to silver ratio and assumes 100% metallurgical recoveries. True width is approximately 75 to 85% of Thickness.

Drill results from holes located adjacent to the SITLA lands and drilled by previous companies show similar gold intercepts.

* Gold Equivalent (AuEq) calculated using a 61.9 gold to silver ratio and assumes 100% metallurgical recoveries. True width is approximately 75-85% of Thickness.

In addition to the drilling, TMI has assay results from surface rock chip and channel sampling in and around the SITLA lands which include numerous samples of +1 g/t gold. These results include a 0.91 metre Etna vein sample averaging 0.73 oz/t gold reported by Lee Perry in Utah Geology, Vol 3, No. 1 Spring 1976. TMI also has results from past surface channel sampling programs including 1.5 metres of 13.07 g/t Au, which is within a 35.1 metre channel sample averaging 1.25 g/t Au. Other channel samples from the Etna ridge area include 44.2 metres @ 0.85 g/t Au and 13.7 metres @ 0.67 g/t Au.
