TORONTO, June 05, 2018 (GLOBE NEWSWIRE) -- Trigon Metals Inc. (TSX-V:TM) (“Trigon” or the “Company”) is pleased to announce the results of its feasibility study (“Feasibility Study”) prepared by Minxcon (Pty) Ltd (“Minxcon”) on the surface mining areas of the Company’s Kombat operations located in northern Namibia (“Kombat”).
The proposed surface mining operations in the Kombat East and Kombat Central areas (the “Kombat open pits”) represent the first phase of the Company’s life of mine (“LoM”) strategy as presented in the recently published technical report entitled “NI 43-101 Technical Report on the Kombat Copper Project, Namibia”, dated March 22, 2018, including a Preliminary Economic Assessment (“PEA”). Future phases of the strategy comprise the recommencement of the various historic underground mines at Kombat, starting with the Asis Far West underground mine (“AFW”), as well as surface mining at Gross Otavi, and ultimately back into Asis West to mine the gap area and explore the resource at depth.
The positive after tax net present value (“NPV”) of US$4.6 million (at a base case copper price of US$3.10/lb) (US$6.5 million at a high case copper price of US$3.28/lb) and healthy internal rate of return (“IRR”) of 103.4% for the Kombat open pits as presented in the Feasibility Study confirm the robust nature of the Kombat operations.
Stephan Theron, President and CEO of Trigon, commented: “The completion of the feasibility study is a major milestone for the Company and its stakeholders. We are extremely pleased with the positive results and look forward to taking the next steps towards production and further development. We have submitted the Feasibility Study results to our offtake and project finance partner and expect sign off and the availability of the funding facility in the near term.”
A NI 43-101 technical report with respect to the Feasibility Study will be filed under the Company’s profile on SEDAR within 45 days of this press release.
Financing Facility
As previously announced, Trigon, together with its 80% owned subsidiary, Manila Investments (Pty) Ltd (“Manila”), has agreed to terms with a major international trading house for a copper concentrate offtake from Kombat (the “Offtake”) and a financing facility of up to US$7.7 million (the “Facility”) to fund the restart of open pit mining.
Trigon will act as guarantor for the Facility, and security will include first ranking charges and security interest over all present and future property and assets of Manila.
The terms of both the Offtake and the Facility are subject to various conditions precedent, including final due diligence and approvals from the trader, which are in the process of being completed.
Feasibility Study Results
Based on the Mineral Resource Estimates for the Kombat East and Kombat Central areas as presented in the table below, the Kombat open pits have an NPV of US$4.6 million, at a real discount rate of 7.6%, which represents a payback period of 1.6 years and a highly attractive IRR of 103.4%.
The Company still plans to undertake additional drilling in the surface mining area with the goals of: (i) increasing the open pit Mineral Resource within the current pit boundaries, (ii) drilling between the Central and East pits, outside of the existing pit boundaries, and (iii) testing potential to the north and west of these areas. The three phase drilling program to extend the current open pit Mineral Resource comprises a further 34 holes, with an aggregate of 1,437 meters to be drilled, and may represent potential upside on the Feasibility Study results.

Capital expenditure
The start-up capital required for first production from the Kombat open pits is estimated at US$6.4 million, including contingencies. This includes US$4.7 million for refurbishment of the existing mill and concentrator at a capacity of 35kt per month and phase 1 of a new tailings storage facility. The plant and infrastructure can also be used as a base for future underground operations as presented in the PEA dated March 22, 2018 as referred to above, but may require further expansion capital.
Revenue and operating costs
The Kombat open pits are forecast to generate revenue of US$58.7 million over their LoM, based on the following commodity price forecasts (in real terms) as used in the Feasibility Study.

| Silver | US$/oz. | 17.60 | 17.80 | 18.10 |
| Copper | US$/tonne | 6,895 | 6,779 | 6,803 |
| Copper | US$/lb | 3.13 | 3.07 | 3.09 |
Direct cash costs (C1) for the Kombat open pits consist of mining and plant operating costs, concentrate transport costs, treatment costs and refining costs. Other cash costs (C3) include corporate overheads and the Namibian revenue royalty of 3%. The Kombat open pits have an estimated all-in sustainable cost of US$2.64/copper equivalent pound (“CuEq lb”).
The turnover, cost and earnings numbers are displayed in the table below per recovered copper equivalent pound.

Cash flows
The Kombat open pits are forecast to generate US$5.7 million of free cash flows over the three year LoM, which cash is expected to be applied to the second phase of the Company’s operations, being exploration and development at AFW.
AFW Pre-Feasibility Study
As previously announced, in conjunction with the Feasibility Study, the Company has undertaken a Pre-Feasibility Study on AFW, split into two phases being exploration and development, and mining.
Environmental Permitting
The Company applied 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 at AFW, and awaits approval from the relevant Namibian authorities.
