TORONTO, ONTARIO--(Marketwired - June 5, 2017) -

HIGHLIGHTS

• Inferred Mineral Resources of 6.905 million tonnes at a grade of 2.78% copper, 1.14% lead and 19.11 g/t silver.
• Positive NPV of US$72 million and an excellent internal rate of return of 45.5%.
• Combined open pit and underground life of mine of nine years at an average mined grade of 2.83% copper, producing 122,106 CuEq tons.
• C1 cash cost of $1.33/lb.
• Total direct capital expenditure over the life of mine of US$67.21 million.
• Phase 1 strategy of open pit mining to facilitate early cash flow generation only requiring start-up capital of US$7.73 million.

Trigon Metals Inc. (TSX VENTURE:TM) ("Trigon" or the "Company") is pleased to announce the filing of its National Instrument 43-101 compliant technical report ("the technical report"). This follows the Company's press release issued on April 20, 2017 announcing an updated Inferred Mineral Resource estimate at the Company's Kombat operations located in northern Namibia ("Kombat").

In conjunction with the technical report, the Company has also completed a scoping level study on the Kombat operations, in the form of a preliminary economic assessment ("PEA"), 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$72 million and a robust internal rate of return of 45.5%.

Stephan Theron, President and CEO of Trigon, commented: "We are pleased to have completed the technical report and PEA in order to take the Company one step closer to its near-term strategy of open pit mining. The results of the work done have confirmed our internal evaluation of this attractive and exciting project and we look forward to moving the Company forward to production."

Phase 1 - Open Pit Mining

The Company remains focused on its phase 1 strategy of open pit mining in the Kombat Central and East areas to facilitate early cash flow generation. As set out below, the start-up capital required for first production of the open pit amounts to US$7.73 million, which includes: power, water and other infrastructure requirements; contractor mobilization and site establishment; refurbishment of the existing mill; studies and design and working capital. Although the capital cost of the mill refurbishment is expected to be financed by the proceeds from open pit mining; the mill is expected to be utilized for future underground operations long after the depletion of the open pit reserves.

Technical report

The updated Mineral Resource estimate reported on April 20, 2017 was in respect of the Kombat West, Central and East, Asis Far West, Asis Gap and Asis West areas. The Company is pleased to have subsequently included additional Inferred Mineral Resources at Gross Otavi, resulting in total Inferred Mineral Resources of 6.905 million tonnes at a grade of 2.78% copper, 1.14% lead and 19.11 g/t silver, as set out in detail in the table below.

Combined Inferred Mineral Resources for the Kombat Operations as at April 2017

Notes:

1. Historical mine voids have been depleted from the Mineral Resource.
2. Historical mine voids were not available for Gross Otavi so the tonnage has been reduced by 1% for historical mining.
3. Additional 7.5% porosity factor has been applied to Gross Otavi for the karst voids.
4. The open pit Mineral Resource is declared to a depth of 150m with a CuEq cut off of 0.77%.
5. The underground Mineral Resource (below 150m) is declared at a CuEq cut off of 1.4%.
6. No tailings have been declared at a 0.4% Cu cut off (upside potential at 0.3% Cu cut-off).
7. Densities for the hard rock material have been modelled.
8. A geological loss of 15% has been applied to the Mineral Resource.
9. All reported Mineral Resources are limited to fall within the property boundaries of the project area.
10. Columns may not add up due to rounding.
11. Inferred Mineral Resources have a large degree of uncertainty as to their existence and whether they can be mined economically. It cannot be assumed that all or any part of the Inferred Mineral Resource will be upgraded to a higher confidence category.

Preliminary Economic Assessment

The purpose of the PEA was to investigate the economic viability, upside potential as well as future exploration requirements of open pit and underground mining targeting the copper and lead resources at Kombat East, Kombat Central, Asis Far West, Asis West and Gross Otavi, taking into consideration mining methods, treatment methods and development of additional infrastructure. The PEA has been based on the total Inferred Mineral Resources as set out above.

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 all-in sustainable cost of US$109/milled tonne that equates to US$1.77/copper equivalent pound ("CuEq lb"). The turnover, cost and earnings numbers are displayed in the tables below per milled tonne and per recovered copper equivalent pound.

Using the discounted cash flow method to calculate the NPV and the intrinsic value (fundamental value based on the technical inputs, and cash flow projection that creates an NPV) in real terms, the Kombat operations have a best-estimated net present value of US$72 million at a real discount rate of 11.02%, a payback period of less than 5 years and an internal rate of return of 45.5%.

The following commodity price forecasts were used in the discounted cash flow model in the PEA.

Item	Unit	2018	2019	2020	2021	Long-term
Silver	US$/oz	17.42	17.76	18120	18.14	18.16

The PEA is preliminary in nature, and it 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 preliminary economic assessment will be realized.
