Oman Antimony Roaster - Capital Budget Update

Tri-Star Resources plc (AIM: TSTR), the independent mining and mineral processing company, announces that the Board of Strategic & Precious Metals Processing LLC ("SPMP") has approved an increased capital budget of US$3.4 million to US$65.5 million with respect to the construction of the Oman Antimony Roaster ("OAR"). Tri-Star has a 40% equity interest in SPMP. 

As was announced by Tri-Star on 28 April 2016, the Board of SPMP decided earlier in the year to progress technical work on incorporating a process utilising existing equipment in OAR to recycle and recover precious metals (the "Gold Recovery Process"). The Board of SPMP has now unanimously resolved to approve the incremental capital cost of including this facility.

SPMP's Board has approved the capital cost of the OAR project of up to US$65.5 million, previously US$62.1 million, which is expected to be funded from existing SPMP facilities. The inclusion of the Gold Recovery Process is an important and logical next step for OAR as it allows the project to accept a wide range of antimony feedstocks, including those associated with gold. This added capability also opens up a significant and new revenue stream for the project, with SPMP believing it potentially increases the plant revenue opportunity by a further 50%. Furthermore, the knowledge gained from the operation of this gold recovery plant will provide SPMP with valuable engineering design and operating information for future refractory gold processing initiatives.
