TriMetals Mining Inc. to Restart Drilling at Gold Springs

VANCOUVER, September 19, 2019 -TriMetals Mining Inc. (TSX:TMI)(OTCQB:TMIAF), (the "Company" or "TMI"), is pleased to announce that in early October it will be initiating a new drilling program at its Gold Springs project located in Nevada and Utah.

The initial focus of the drill program will be the Homestake patented claims (the "Homestake target") located on the Nevada side of the Gold Springs project, 700 metres east of the Grey Eagle resource, and adjoining to the north to Newmont Goldcorp Corp.'s mining claims. In operation during the late 1800s and early 1900s, the Homestake Mine was one of few in the area with mill facilities. TMI is the first group to have been granted a lease on the Homestake patented claims and it will be conducting the first modern exploration program since the Homestake mine finally became idle in the early 1940's.

Matias Herrero, President & CEO of TMI stated, "Now that the arbitration with Bolivia is concluded, and the sale of the Escalones copper project is nearing completion, we are well on our way to becoming a leaner, more competitive, gold-focused company. We are enthusiastic to return to exploring the Gold Springs project and drill-test the Homestake historic mine area. Since its acquisition last year, we have looked forward to being the first company in modern times to have the opportunity to explore this gold system. Our goal for this initial drill program is to restart the process of adding to our existing resources at Gold Springs, and to continue to demonstrate the multi-million ounce potential of the Gold Springs project, in southern Utah and Nevada, both, top-ten mining jurisdictions in the world."¹

Technical Information About Our New Drilling Program

The drill program at the Homestake target will consist of approximately 3,000 metres of reverse circulation ("RC") drilling and the length of the program may extend to the spring of 2020 as winter delays can be expected. Results are expected in December 2019 and early 2020.

The Homestake target is highlighted by two main parallel 3-4-metre-thick gold-bearing veins which have returned high-grade results from surface samples collected by the Company. These two veins are separated by 20-30 metres of brecciated and silicified rocks which have returned intermediate gold grades and represent a priority target along with the enclosing veins. This package of veins and breccia is surrounded by a wide stockwork zone containing low-grade gold values. Drilling will focus on the surface-exposed 650 metre strike length of the Homestake vein system along with the enclosed breccia and surrounding stockwork zones. This entire system has a surface-exposed width of approximately 400 metres and is offset by faulting along the eastern margin.

The drill program will additionally test the high-grade Iris vein located 200 metres to the west of, and dipping back toward, the Homestake veins and breccia zones. The Company believes the configuration of the Homestake-Iris vein intersection is consistent with classic models for epithermal vein systems and often represents where bonanza gold grades are found in these environments. TMI projects the Homestake-Iris vein intersection to be at a depth of approximately 150 metres and will be one of the targets in this drill program.
