Toronto, Canada – March 23, 2018 – Trigon Metals Inc. (TSX -V: TM) (“Trigon” or the “Company”)

is pleased to announce the filin g of its National Instr ument 43 -101 compliant technical report

(“the technical report”). This follows the Company’s press release issued on February 6, 2018

announcing an updated Mineral Resource estimate at the Company’s Kombat operations located

in northern Namibia (“Kombat” or the “Kombat Mine”).

The Company confirms its M ineral Resource estimate for the Kombat Mine, comprising both the

surface accessible (targeted open pit) and underground, of 1.529 million tonnes of Indicated

Mineral Resources at a grade of 1.14% copper, 0.72% lead and 2.88 g/t silver and 5.511 million

tonnes of Inferred Mineral Resources at a grade of 3.05% copper, 1.25% lead and 22.93 g/t silver

In conjunction with the technical report, the Company has al so further optimized the preliminary

economic assessment (“PEA”) on the Kombat operations , the results of which are summarized in

the technical report. The PEA confirms that the Kombat operations have a best-estimated net

present value (“NPV”) of US$96 million and a robust internal rate of return of 85.2%.

Stephan Theron, President and CEO of Trigon, commented: “We are extremely pleased to provide

this positive information to the market, and to have achieved one more milestone towards our

target of open pit production during 2018.”

for Kombat.

2. The underground Mineral Resource (below 150 m) is declared at a CuEq cut off of 1.4 %.

The Company still plans to undertake additional drilling with the goals of: (i) increasing the open

pit Mineral Resource within the current pit boundaries, (ii) drilling the gap between the Central

and East pits, which is outside of the existing pit boundaries, and (iii) testing potential to the north

and west of these areas. The three phase dr illing program to extend the current open pit Mineral

Resource comprises a further 34 holes, with an aggregate of 1,437 meters to be drilled.

Updated PEA

The Company has further optimized the financial model in the updated PEA as announced in the

press release issued on February 6, 2018 (the “Updated PEA”).

The Updated PEA has been based on the Min eral Resource Estimate as set out above, and

incorporates current forecast commodity prices , results of metallurgical testing undertaken in

2017 and offtake terms for copper concentrate as agreed with a major international trading house

as announced on October 26, 2017. All other assumptions used in the PEA , including capital

expenditure and operating costs, remain unchanged at this stage.

Using the discoun ted cash flow method to calculate the net present value (“NPV”) in real terms,

the Kombat operations are projected to have a further improved estimated NPV of US$96 million

at a real discount rate of 10.92%, a payback period of 3.6 years and a highly attractive internal rate

of return of 85.2%.

Production and processing

The combined open pits and underground mines have a potential life of mine (“LoM”) of eight

years mining 4,071 kt at an average mined grade of 2.84% copper as set out in the table below.

Capital

The start-up capital required for first production of the open pit amounts is estimated at US$7.16

million. Total direct capital expenditure over the LoM is estimated at US$67.69 million (excluding

contingencies and stay in business capital ) with the peak capital expenditure during years 2021

and 2022, and peak funding requirement of an estimated USD$30.15 million during 2021.

Operating costs and commodity prices

Direct cash costs (C1) for the Kombat operations consist of plant and mining operating costs ,

concentrate transport costs, treatment costs and refining costs. Other cash costs (C3) include

corporate overheads and the Namibian revenue royalty of 3%. Kombat has an estimated all-in

sustainable cost of US$1.81/copper equivalent pound (“CuEq lb”). The turnover, cost and earnings

numbers are displayed in the table below per milled tonne and per recovered copper equivalent

pound.

The Updated PEA is preliminary in nature, and includes inferred Mineral Resources that are

considered too speculative geologically to have the economic considerations applied to them

that would enable them to be categorized as Mineral Reserves. There is no certainty that the

results of the Updated PEA will be realized.

A further update of the Updated PEA will be undertaken as part of the feasibility study referred to

below.

The technical report entitled “NI 43 -101 Technical Report on the Kombat Copper Project,

Namibia”, dated March 22, 2018 with an effective date of February 28, 2018 , was prepared for

Trigon by Uwe Engelmann (BSc (Zoo. & Bot.), BSc Hons (Geol.), Pr.Sci.Nat. No. 400058/08, MGSSA)

of Minxcon, and is available under the Company's profile on SEDAR at www .sedar.com and on the

Company's website at www.trigonmetals.com.

Feasibility Study

As previously announced by the Company, t he Mineral Resource Estimate will form the basis for a

feasibility study, including a feasibility analysis on the surface mining areas and a pre -feasibility

design on the Asis Far West underground mine.

The feasibility study was initiated in January 2018 and is progressing well. The process is

anticipated to take approximately five months to complete , during which time, the Company

intends to commence with the refurbishment of the mill and concentrator to facilitate timelines

for commencement of open pit mining and the processing of ore therefrom.

The Company does not currently have a feasibility study in respect of the Kombat M ine and

production restart activities are based on internal management forecasts.

Environmental Permitting

The Environmental Impact Assessment reports, including required specialist studies and an

Environmental Management Pl an, are in the process of being finalized . The Company will then

apply to secure the Environmental Clearance Certificate required for open pit mining and

associated activities, as well as that needed for exploration activities for underground mining.

Qualified Person

Mr. Uwe Engelmann (BSc (Zoo. & Bot.), BSc Hons (Geol.), Pr.Sci.Nat. No. 400058/08, MGSSA) of

Minxcon, is a “qualified person “ as such term is defined in NI 43 - 101 and has reviewed and

approved the technical information and data included in this press release. As a director of

Minxcon, Mr. Engelmann is considered independent.

Trigon Metals Inc.

Trigon is a publicly traded Canadian exploration and development company with its core business
