TriMetals Mining Inc. Expands Mineralized Zone at The Jumbo Target at the Gold Springs Project in Nevada and Utah Including an Intercept of 118.95 g/t Au and 28.4 g/t Ag over 1.5 metres.

January 28, 2016

January 28, 2016, Vancouver, British Columbia—TriMetals Mining Inc. (TSX: TMI and TMI.B, US OTCQX: TMIAF and TMIBF), (the “Company”), is pleased to announce the results of the 2015 drilling program which shows an expansion of the mineralized zone at the North end of the Jumbo target, together with some high grade intercepts.

The high grade intercept is in the central zone of the Jumbo target within drill hole J-15-003, between 135.6 and 137.2 metres downhole:

Thickness (m)Gold (g/t)Silver (g/t)Gold Equivalent* (g/t)Gold Equivalent* (oz/t)
1.5118.9528.40119.413.839

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

Ralph Fitch, President and CEO of the Company, stated “We know these very high grades exist on the property because we have found them in loose rocks (“float”) in several places on the property, but this is the first time we have intersected these grades in a drill hole. Our exploration focus has been on large open pit resources but there is also the potential for smaller underground operations with these grades”.

Examples of very high grade float samples from the property:

* Gold Equivalent (AuEq) calculated using a 61.9 gold to silver ratio and assume 100% metallurgical recoveries.

The very high grade intercept in drill hole J-15-003 is a small part of the entire 106.7-metre-thick gold bearing zone in the hole. However, it has a very large influence on the average grade of the entire gold bearing zone. In cases like this it is industry practice to “cut” or reduce these values to more typical values. We quote the actual intercept with the high grade value and then repeat the same interval using the average value of the four highest grade drill intercepts in Jumbo veins from previous drilling (18.6 g/t AuEq*), instead of using the very high actual assay of 3.839 AuEq* oz/t. (119.41 g/t AuEq*).

If the high grade intercept of 3.839 AuEq* oz/t is reduced to the average of the 4 highest grade drill intercepts (18.6 g/t AuEq*) previously drilled on the

 

Jumbo, then the intervals would average as follows:

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

** includes a 10.7 metre interval assaying less than 0.1 gt AuEq

Drill hole J-15-003 is in the central zone of the Jumbo target and includes grades higher than those interpreted in the block model used to estimate the resource. Drill hole J-15-003 is located 100 meters north of hole J-14-018 (138.7 m @ 1.01 g/t AuEq, using a silver/gold ratio of 57.14) which was the best intercept from the 2014 drill program.

Drilling (2015) to the North of J-15-003, for the next two hundred metres, typically showed greater widths and better grades than had been seen in earlier drilling. All this mineralization is projected to come up to the surface.

Ralph Fitch stated “the importance of these drill results is they show that the mineralization at the north end of the Jumbo target is stronger than was previously interpreted and is open to further expansion to the North and to depth. This has the potential to enhance our open pit scenario described in our most recent PEA (press release August 12, 2015). At the South end of the Jumbo hole J-15-10 again shows that we can find gold mineralization by following the boundaries of the ZTEM geophysical anomalies. As I have mentioned before we have defined approximately 35 km of ZTEM geophysical features which we believe will be associated with gold mineralization and we have only drilled approximately 3 km to date resulting in the present, reported resource estimate and positive updated PEA*** (M&I resource of 597,000 oz AuEq@0.62 g/t AuEq and an Inferred resource of 306,000 oz AuEq@0.45 g/t AuEq, using a silver/gold ratio of 57.14)”.

The 2015 Reverse-Circulation drill program included 3,132 metres in 14 holes. All drilling was completed in Utah in the Jumbo resource area. The objectives of the program were to extend and better define the mineralization to the north, test for deeper mineralization to the east of the Jumbo Main Zone, explore for down-dip extensions to the mineralization, and to test a ZTEM geophysical anomaly located southwest of the southern extension of Jumbo. All but one of the fourteen holes encountered strong gold mineralization.

Hole J-15-013 tested for extensions to the gold mineralization intersected in hole J-15-003, approximately 50 metres further south, and hole J-15-014 tested for extensions of the gold mineralization approximately 50 metres below hole J-15-003.

Hole J-15-003 was drilled approximately 100 metres north of hole J-14-018 and hole J-15-001 was drilled approximately 50 metres below hole J-14-018, both were designed to explore for extensions to the gold mineralization seen in hole J-14-018. Drill hole J-15-003 intersected strong mineralization as reported above whereas J-15-001 encountered a post-mineral dike (un-mineralized intrusive rock) in the expected location of the gold mineralization and failed to intersect the type of grades seen in hole J-14-018.

Holes J-15-002 and J-15-007 tested the down-dip extensions of the main Jumbo zone. Both holes encountered the same post-mineral dike seen in hole J-15-001 but included part of the mineralized interval.

Holes J-15-006 and J-15-008 tested the deep easterly extension of the system. These holes were drilled well into the hanging wall of the Jumbo mineral system, further east than prior drilling. Strong alteration of the rocks seen in these holes indicates that the mineral system is open to the east.

The Qualified Person on the Gold Springs property is Randall Moore, Executive Vice President of Exploration – North America of TriMetals Mining Inc. and he has reviewed and approved the content of this press release.

Quality Assurance and Quality Control

Approximately 8.2 kg of RC chips are sent to the laboratory for each 1.52 metre drill interval. 15-20% of the samples submitted by the Company are blanks and standards. In addition, the laboratory also includes duplicates of samples, standards and blanks. The results of these check assays are reviewed prior to the release of data.

Assays were performed in Reno, Nevada by Inspectorate America Corporation Laboratories, an ISO 9001:2000 Certified laboratory. Gold was analyzed by fire assay of a 30-gram sample with an AAS finish (FA430). All other elements were analyzed by the 30 element, 4 acid digestion ICP method (MA300). Over-limit assays of Au and Ag were analyzed by fire assay of a 30-gram sample with a gravimetric finish (FA530-Au/Ag)

Gold Equivalence

Unless otherwise indicated, gold equivalent (AuEq) was calculated using a silver/gold price ratio of 61.9.
