TriMetals Mining Inc. Discovers New Areas of Outcropping Gold Mineralization at Gold Springs

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Oct. 16, 2014) - TriMetals Mining Inc. (TSX:TMI)(TSX:TMI.B)(OTCQX:TMIAF)(OTCQX:TMIBF) is pleased to provide an update on the continuing exploration program at the Gold Springs gold-silver project located in Nevada and Utah.

Ralph Fitch, President and CEO of TriMetals Mining Inc. (the "Company") stated, "Our continuing exploration efforts have not only focused on the drill programs at the Jumbo and Grey Eagle resource areas, from where we should be able to report the next batch of drill results within a few weeks, but also the ongoing investigation and evaluation of new areas of gold-silver mineralization on our large 74 sq km land position at Gold Springs. This work continues to demonstrate the abundance of gold-silver target areas in addition to the 18 areas of outcrop we have historically reported. We are making new discoveries with the help of the recently completed LIDAR survey, which can see through the trees to show geology and very small old prospect pits and outcrops which our team has been following up with on-the-ground visits. The LIDAR in conjunction with our ZTEM geophysical survey which shows rocks that are associated with the gold mineralization, and our growing database of geochemistry and geology have proven to be powerful tools for identifying and targeting new areas with high exploration potential. These additional target areas present excellent opportunities for new gold-silver discoveries in this emerging gold district. Now, with a positive PEA, an ongoing drill program intended to expand the resources at Grey Eagle and Jumbo and the ever increasing number of outcropping drill targets bodes well for the continuing success of the project. We continue to drill with the intention of expanding the resource as we move the project closer to production."

One completely new area is the Snow Prospect located approximately 800 metres west of Etna on the Utah side of the property. Rock samples from this structural zone include assays of up to 3.7 gpt Au and 12 gpt Ag over 4.6 metres. Trenching and further sampling will be done in this area to better understand the scale of the target prior to drilling. Samples included:

Another example of an outcrop area is White Point, located 400 metres west of the Grey Eagle resource area, where an expanded sampling program has completed a series of four channel samples. These were continuous chip samples collected from outcropping material and along an old road cut. Samples were cut approximately perpendicular to the strike of the mineralization. The results include:

Ralph Fitch went on to say, "The White Point area geology now shows a drill target which is at least 100 metres wide by 300 metres long before it disappears under gravel cover and its location adjacent to the Grey Eagle resource block makes it a very attractive target."

The White Point area represents a priority target for follow-up drilling where reconnaissance RC holes completed in 2011 returned values of up to 9.1 metres at 1.63 gpt AuEq and 13.7 metres at 0.70 gpt AuEq.

Channel sampling was also conducted on the North Grey Eagle area with positive results, providing another shallow drill target that could potentially extend the Grey Eagle resource. Samples were cut perpendicular to the strike of the mineralization and were continuous chips of outcropping material. The results include:

Field investigations of other areas of historic workings shown on the "bare earth" LIDAR image have found significant zones of veining, brecciation and stockwork development. Sample results from these additional areas are pending.

Drilling has continued at the Jumbo resource area and we have now completed an additional 11 holes which will be reported when results are received, probably within the next few weeks. This program will bring the total holes drilled in the Jumbo area in 2014 to 22, Grey Eagle 9 and Etna 6. The permitting process is also ongoing and we are in the process of completing the Plan of Operations on the Utah side of the project. The Company is already operating under a Plan of Operations on the Nevada side of the project.

What is LIDAR:

LIDAR, which stands for Light Detection and Ranging, is a remote sensing method that uses light in the form of a pulsed laser to measure ranges (variable distances) to the Earth. These light pulses - combined with other data recorded by the airborne system - generate precise, three-dimensional information about the shape of the Earth and its surface characteristics (NOAA.gov website).

The recently acquired LIDAR data at Gold Springs has produced a "bare earth" image removing all of the vegetation from the image. This has not only allowed for detailed structural interpretations and clear outlines of vein traces, but for the identification of all historic shafts, adits and even small isolated pits. Field investigations aided by the LIDAR survey have identified several new target areas. Most areas have assays pending but results have been received for the new Snow target as reported above.

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

The laboratory includes duplicates of samples, standards and blanks in their assay reports. The results of these check assays are reviewed prior to the release of data. All sample assays are also reviewed for their geological context.

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.
