TriMetals Mining Inc. Intersects 67 Metres of 1 g/t AuEq(i) Near Surface at the Jumbo Target on the Gold Springs Project

VANCOUVER, BRITISH COLUMBIA--(Marketwired - July 14, 2014) - TriMetals Mining Inc. (TSX:TMI)(TSX:TMI.B)(OTCQX:TMIAF)(OTCQX:TMIBF), a gold stock, is pleased to announce the results from the first ten Reverse Circulation ("RC") drill holes from the Jumbo Area at the Gold Springs gold-silver project in the mining friendly jurisdictions of Nevada and Utah, USA.

RC hole J-14-004 intersected 67 metres of 1.03 g/t AuEq* in the southern portion of the Jumbo resource block. The hole successfully extended the mineralization located in 2013 in RC holes J-13-005 and 006 both along strike and down-dip.

Ralph Fitch, President and CEO of TriMetals Mining Inc. (the "Company") stated "These results expand the mineralized zone at Jumbo where we have established a mineral resource (Amended PEA filed on July 8, 2014) at Gold Springs. They also further confirm the continuity of the higher-grade mineralization first located by the 2013 drill program. As I stated previously, the significant upside the Company has is that less than 10% of the prospective areas at Gold Springs have been drilled, so there is a significant opportunity to expand the current zone of gold-silver mineralization through drilling. This could further enhance both the project and the Company's value as we move the project closer to production."

The results from J-14-001,002 and 003 also strongly support this higher grade zone of mineralization as shown below. These holes as a group extend the previously known mineralization envelope and confirm the importance of the 2013 Jumbo intercepts in J-13-005 and 006 and exhibit higher grades than are typically found in the Jumbo Zone:

Drill hole J-14-001 and J-14-004 intersected the full width of the mineralized body whereas holes J-14-002 and 003 ended in mineralization suggesting the mineralized body is likely thicker than reported. J-14-003 extended mineralization beyond the previously known mineralization boundary. This higher grade block of mineralization extends for approximately 200 metres north-south and is open for expansion to the north and east.

RC holes J-14-005 through 010 all contain additional mineralization except for J-14-007 which was drilled to the east and remained in post mineral rocks above a fault and J-14-008 drilled to the NW in the south end of the zone did not intercept the main target due to faulting. RC hole J-14-010 is noteworthy in that it is located approximately 100 metres north of the Jumbo resource area and intersects what is interpreted as a new zone of mineralization east of the main trend. This hole intersected 25.9 metres at 0.65 g/t AuEq*

Sections showing the location of the reported holes can be found on the Company's website at: www.trimetalsmining.com

The drill program at Gold Springs started at Jumbo where 11 holes have been drilled, it then moved to the Etna target, 2 km south of Jumbo, which was chosen as the third target for this year's drill program. Six exploration holes were completed on the Etna target and then the drill was moved to Grey Eagle where it will explore the potential on the south end of the Grey Eagle resource area. Four holes have now been completed at Grey Eagle, all of which intersected the extensions of the vein/stockwork zone intersected in last year's drill program. Samples from these holes are presently in the laboratory for assaying.

Three bulk samples of coarse broken mineralized rock from the Grey Eagle trench have been collected for metallurgical testing and have been sent to the Kappes Cassiday metallurgical laboratory for bottle roll and column testing. Also a metallurgical test program designed to enhance silver extraction has been set up using existing RC chip samples as well as trench samples.

Qualified Person

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 5.5 kg of RC chips are sent to the laboratory for each 1.52 metre drill interval. 5% 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. All RC chip sample assays are also reviewed for their geological context and checked against the drill logs.

Assay Method: Assays were performed in Reno, Nevada by Inspectorate 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 30element, 4 acid ICP method (MA330).

Gold Equivalence: AuEq* was calculated using a gold/silver ratio of 57.14 to be consistent with that used for previously reported drill results and have not been adjusted for metallurgical recoveries.
