TriMetals Mining Inc. Intersects 38 metres of 1 g/t AuEq(i) including 7.6 metres of 3.2 g/t AuEq at the Jumbo Target on the Gold Springs Project

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Aug. 1, 2014) - TriMetals Mining Inc. (TSX:TMI)(TSX:TMI.B)(OTCQX:TMIAF)(OTCQX:TMIBF), a gold stock, is pleased to announce the results from an important additional Reverse Circulation ("RC") drill hole from the Jumbo Area and six RC holes from the Etna Area at the Gold Springs gold-silver project in the mining friendly jurisdictions of Nevada and Utah, USA.

RC hole J-14-011 intersected 38.1 metres of 1.01 g/t AuEq(i), including 7.6 metres of 3.21 g/t AuEq(i), to the east of the center portion of the Jumbo resource block where previous drilling was done in this sector. Further drilling will be needed to better understand the relationship of this mineralization to that to the North and to the South due to east-west faulting in the area. The indications, however, are that this intercept extends the 200m long higher grade southern Jumbo zone, which includes the 67m@1.03 g/t AuEq* in hole J-14-004, reported in the previous news release (NR14-16, July 11, 2014) for an additional 100 metres to the north.

Azimuth 270°, declination -55°. Cut off 0.1g/t AuEq. *Gold Equivalent ("AuEq") uses a Au/Ag ratio of 57.14 and assumes 100% metallurgical recoveries.

Ralph Fitch, President and CEO of TriMetals Mining Inc. (the "Company") stated "These results again expand the mineralized zone at Jumbo where we have established a mineral resource (Amended PEA filed on July 8, 2014). It also demonstrates that as we continue the drill program we continue to expand the mineralization and get ever closer to our near term goal of a million ounces AuEq*. As I keep restating, the significant upside the Company has, is that less than 10% of the prospective areas at Gold Springs have been drilled."

Six RC holes were also completed on the Etna target approximately 2 km south of the present Jumbo Resource Block. Etna was chosen as the next target to test because of extensive outcrops of gold mineralization.

RC hole E-14-001 intersected mineralization over 106.7 metres @0.49 AuEq* and included 29 metres of 1.03 g/t AuEq*. This broad zone relates to RC hole E-12-001 drilled approximately 50 metres to the north which intersected 125 metres of 0.35 g/t AuEq* including 39.6 metres of 0.64 g/t AuEq*. More drilling is required to further define this new zone and its extensions which have the potential to be substantial because of the large intercept widths.

91.4 93.0 1.6 4.86 17.1 5.16 1.4

The remaining five holes at Etna were exploratory in nature and intersected weak mineralization often over broad widths. Further geological and geophysical analysis and additional drilling is required in the Etna zone to follow the extensions of the mineralized body found in E12-001 and E14-001.

The drill program at Gold Springs started at Jumbo where eleven 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 eleven holes have been completed. Samples from the Grey Eagle holes are presently in the laboratory for assaying.

The following lists the results from all the six Etna RC holes:

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.
