TriMetals Mining Announces Results of 2016 Drill Program at Jumbo Target

TriMetals Mining Inc. (TSX: TMI) (TSX: TMI.B) (OTCQX: TMIAF) (OTCQX: TMIBF), (the "Company"), is pleased to announce the results of the first seven holes from the 2016 drill program at Jumbo. The results clearly demonstrate an extension of the mineralized zone to the east and south, with grades higher than the resource average grade reported in the Preliminary Economic Assessment ("PEA") (PR 15-10 of August 12, 2015).

This new series of intercepts show a consistent set of results above 1 g/t gold equivalent*.

The best intercepts are shown below.

Drill Hole Thickness (m) Gold (g/t) Silver (g/t) Gold Equivalent* (g/t) Gold Equivalent* (oz/t)
J-16-006 48.8 0.686 23.71 1.07 0.034
J-16-004 30.5 0.497 32.64 1.02 0.033
J-16-003 22.9 0.789 14.21 1.02 0.033
J-16-005 12.2 0.565 34.90 1.13 0.036

* Gold Equivalent ("AuEq") calculated using a 61.9 gold to silver ratio and assumes 100% metallurgical recoveries. True width is approximately 80-90% of Thickness. These holes are the down-dip extension of the similar grade mineralization drilled in 2014 and 2015 on this part of the property.

Ralph Fitch, President and CEO of the Company, stated, "This extension to the mineralization in south Jumbo starts the process of filling in the eight-kilometre long Jumbo Trend. By the end of the year we also plan to complete resource expansion drilling in the northern portion of the Jumbo Trend approximately 1.3 km to the north of the holes reported here, and in the southern portion of the Jumbo Trend at the historic Etna mine target, some two km further south, where surface outcrop samples have assayed greater than 1 g/t gold (see PR 16-01 of January 27, 2016). The importance of the Jumbo Trend is that 75% of our present resource has been drilled in a 1.3 km segment of the Trend and we are now starting to expand beyond this segment into other parts of the eight-kilometre Trend where we are also finding mineralization. Our presently reported resource includes 597,000 oz AuEq** in the Measured and Indicated category and 306,000 oz of AuEq** in the Inferred category."

**Based on an updated mineral resource estimate for the Jumbo Zone and the Grey Eagle Zone at the Gold Springs gold-silver project with an effective date of June 3, 2015 (See News Release dated June 3, 2015). Gold Equivalent ("AuEq") in the updated mineral resource estimate was calculated using a 57.14 gold to silver ratio and assumed 100% metallurgical recoveries.

The table below shows the details of the drill results obtained.

J-16-001 and J-16-002 were drilled into the footwall of the mineralization, west of hole J-16-003, and both holes intersected weak mineralization. Hole J-16-007 was drilled vertically down a structure and also intersected weak mineralization.
