TriMetals Mining Inc. to Restart Drilling at Gold Springs

Vancouver, British Columbia—September 19, 2019

TriMetals Mining Inc. (TSX: TMI, US 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 Corporation’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 world1”.

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.
