Preliminary third party technical report outlines opportunity for refractory gold

Tri-Star announces that it has received a preliminary third party independent technical report commissioned to review the Company's proprietary "clean roasting" technology and specifically its application to refractory gold.

The report, prepared in connection with the Company's agreed conditional deal to sell its intellectual property rights to joint venture company Strategic & Precious Metals Processing LLC (as previously announced on 5 June 2015) highlights four key attributes pertaining to Tri-Star's technology:

- Tri-Star's clean roasting technology, which is a two-step process consisting of a reduction roast followed by an oxidation roast, is confirmed as a viable technology for treating refractory gold ores;

- The report's preliminary economic assessment based on a representative suite of feed-stocks generates an estimated Net Present Value of close to US$1 billion and an Internal Rate of Return of 45%. This is based on a nominal 500,000tpa processing facility based in the Middle East producing 500,000 ounces of gold per annum;

- A detailed comparative analysis of 39 selected gold projects either at advanced stages of development or nearing production highlighted major competitive advantages that the Tri-Star technology and facility could offer;

- The clean roasting technology provides a process for refractory gold concentrates treatment which should be highly efficient and cost effective with distinct advantages over competing treatment processes combined with full environmental compliance.

Emin Eyi, Managing Director of Tri-Star, said: "We are delighted that this new report prepared by an independent third party expert in refractory gold has confirmed materially improved economics for our clean roasting technology compared with earlier assessments announced to the market on 20 December 2013 and also that our technology can be increasingly competitive in this large and important refractory gold market."
