TMI Sharpens its Focus on Gold and Provides Update on Exploration &
Business Development Progress
VANCOUVER, British Columbia, April 26, 2018 -- TriMetals Mining Inc. (TSX:TMI), (“TMI” or “the Company”), is pleased to
announce that exploration and permitting activities have commenced for the field season at its flagship Gold Springs Project in
the western U.S.A. and that several site visits with prospective strategic partners have been completed at the Escalones
copper-gold project in Chile.
Highlights
• Positive rock chip sampling results from the South Jumbo and new Homestake targets at TMI’s Gold Springs Project;
• Field exploration work and permitting activities have commenced at the Gold Springs Project; and
• Site visits to Escalones Project completed with potential strategic partners.
Eric Edwards, President and CEO of TMI, said, “At the Gold Springs Project, we have commenced our field exploration
activities for 2018, including surface sampling, mapping, refining the resource model and continuing the structural analysis to
connect the North Jumbo and South Jumbo targets. Our long-term cultural assessment and permitting activities initiated last
year are continuing in order to satisfy requirements for future district-wide permits”.
“In summer 2018, we will focus our program on the 5.5 kilometer long Jumbo Trend, examining the structural offsets and
lithological complexities to determine potential continuity of the north and south resources areas. We are working toward our
goal to identify 3.0 million oz of gold in Jumbo mineral resources.”
Turning to the Escalones Project, Mr. Edwards continued: “We are pleased with the level of interest from prospective, high-
quality potential partners for our Escalones copper-gold project. The current exciting copper market has provided a window of
opportunity to TMI to seek a value-accretive partnership from a cross section of mid-tier producers and explorers with
experience, teams and skills in the South American copper belt. While the process of evaluation is ongoing, the positive
response has reinforced our view of the potential at Escalones and that the project can be more rapidly advanced and
contribute value to TMI shareholders by combining efforts in a potential partnership.”
In other matters, regarding the international arbitration case on the Company’s former Bolivian asset, TMI anticipates that a
ruling of the International Court of Arbitration may be issued within the next few months. Following the delivery of the ruling,
Bolivia will have two levels of appeal process available, and those appeals could take up to two years after receiving the ruling.
Mr. Edwards commented, “We remain optimistic of a favorable outcome.”
Gold Springs Project Exploration Update
Encouraging results were received from a surface sampling program completed at the end of 2017 on the South Jumbo and the
Homestake Target, newly acquired in 2017. See Appendix 1, 2, 3 following.
The Gold Springs Project straddles Nevada and Utah, located approximately 120 air km northeast of Las Vegas and 75 air km
northwest of Cedar City, Utah.
The exploration staff is evaluating past drilling and the recent surface sampling results to better understand the controls for the
higher-grade gold mineralization and to refine the geologic model to optimize future drill programs. These programs would be
designed to locate additional + 1 g/t gold mineralization and to expand the existing resources at the North and South Jumbo
targets.
In addition to the Jumbo targets, sampling has confirmed high-grade gold mineralization at the newly acquired Homestake
Target. These results are being incorporated into the geologic mapping in order to develop priority drill targets at Homestake.
The scope of the exploration program and any drilling for 2018 will be subject to availability of financing.
Gold Springs Project – South Jumbo Target
The South Jumbo Target lies along the 5.5 km long Jumbo Trend, within the eastern portion of the Gold Springs Project in
Utah.
TMI has identified at the South Jumbo Target measured resources of 2.1 million tonnes at 0.64 g/t gold and 6.91 g/t silver;
indicated resources of 3.2 million tonnes at 0.58 g/t gold and 6.24 g/t silver; and inferred resources of 1.4 million tonnes at
0.50 g/t gold and 5.27 g/t silver. Please refer to the technical report titled: “Amended Technical Report and 2017 Mineral
Resource – Gold Spring Project” dated July 27, 2017 and with an effective date of March 29, 2017 which has been filed at
www.SEDAR.com (the “Gold Springs Technical Report”) for important Qualified Person, technical and other disclosures.
South Jumbo resource is a shallow mineralized zone which has been tested to a depth of 150 meters (“m”) and over a north-
south strike length of 600 m. The resource remains open at depth and along strike in both directions.
The rock chip sampling demonstrates the mineralization can be traced along strike for almost a kilometer beyond the current
defined resource before being obscured by post mineral cover.
The 178 surface samples were designed to test for surface projections of the higher-grade material seen in the 2016 and 2017
drill results at South Jumbo, and to test for projections of this material into areas outside of the defined resource. The sampling
was successful in achieving both these goals with the rock chip sampling results highlighted by high-grade values as high as
53 g/t gold with 106.9 g/t silver and 35.4 g/t gold with 316.0 g/t silver as well as demonstrating evidence of mineralization
across the entire 1.5 km of exposed strike length at South Jumbo. Multiple samples of greater than 10 g/t gold highlight the
potential for high-grade zones within a broad, lower-grade shell that was identified from drilling in 2016 and 2017 (samples
ranged from <0.005g/t gold and <0.5 g/t silver to 53.0 g/t gold and 316.0 g/t silver).
It will require follow-up drilling to test that the high-grade gold and silver mineralization is continuous from surface to depth and
to expand the current defined resource.
Gold Springs Project – Homestake Target
Surface sampling results from the Homestake Target confirm the high-grade nature of the gold mineralization and its
continuation from the veins into the surrounding breccia and stockwork zones. Gold mineralization has now been traced for 1.8
km along the north-south strike with some portions projected under post- mineral cover.
The surrounding breccia and stockwork zones are exposed over an east-west width of 400 m before their projection under post
-mineral cover. A total of 75 samples were collected over the 1.8 km strike of the Homestake system. This rock chip sampling
produced several positive gold and silver values which included 62 g/t gold with 82 g/t silver and 8.0 g/t gold with 746.6 g/t
silver in areas of brecciation outside of the veins (samples ranged from <0.005g/t gold and <0.5 g/t silver to 53.0 g/t gold and
316.0 g/t silver).
The surface sampling program was the first step in scoping an exploration program and drill targets for the Homestake Target,
which is located 1 km northeast of the Grey Eagle Target where TMI has defined measured resources of 2.8 million tonnes at
0.65 g/t gold and 7.26 g/t silver; indicated resources of 4.3 million tonnes at 0.59 g/t gold and 7.11 g/t silver; and inferred
resources of 0.9 million tonnes at 0.43 g/t gold and 6.37 g/t silver. Please refer to the Gold Springs Technical Report for
important Qualified Person, technical and other disclosures.
Escalones Copper Project, Chile
In February 2018, TMI initiated a program to seek a strategic partner to advance the Escalones Project towards feasibility. The
Company’s strategy is to a structure a strategic partnership by retaining a mineral royalty, a minority stake and/or an equity
position in the partnership to share in the future success of the Escalones Project.
The Escalones Project is located 35 km east of Codelco’s El Teniente Mine, the largest copper underground mine with one of
the largest copper reserves in the world. The Escalones Project was internally discovered by TMI through greenfield exploration
work.
An Amended Technical Report prepared by Hard Rock Consulting, LLC titled “Resource Estimate on the Escalones Porphyry
Copper Project” and dated July 11, 2014 with an effective date of June 28, 2013 (the “Escalones Technical Report”) stated that
the project has:
• Indicated Resources of 232.6 million tonnes at average grades of 0.31% copper, 0.07 g/t gold, 0.66 g/t silver, and
0.006% molybdenum, containing approximately 1.6 million pounds of copper, 0.5 million ounces of gold, 4.9 million
ounces of silver, and 31.9 million pounds of molybdenum, and
• Inferred Resources of 527.7 million tonnes at average grades of 0.34% copper, 0.04 g/t gold, 0.85 g/t silver, and 0.007%
molybdenum, containing approximately 4.0 million pounds of copper, 0.6 million ounces of gold, 14.4 million ounces of
silver and 79.5 million pounds of molybdenum.
Exploration work on Escalones was halted by the Company in 2014 due to low copper prices. Please refer to the Escalones
Technical Report available on the Company’s website and on www.SEDAR.com for important Qualified Person, technical and
other disclosures.
