Tri-Star Resources plc announced that  Strategic & Precious Metals Processing LLC ("SPMP"), owner of an antimony-gold processing facility  in the Port of Sohar Free Zone, located in the Sultanate of Oman, has produced its first antimony metal.  Tri-Star has a 40% shareholding in SPMP with the other joint venture partners being The Oman Investment Fund ("OIF") (40% equity holder) and DNR Industries Limited, part of Dutco Group in Dubai (20% equity holder). Following the completion of the remedial works to one of the two SPMP antimony smelting furnaces ('RF1') and the installation of a new gas cooling solution, first antimony has been produced at a purity of 98%.  As production increases, this is expected to rise to in excess of 99.65%, the level required for commercial sale. With the process proven, SPMP intends to begin the immediate ramp up of production with and to commence replicating the successful remedial works conducted at RF1 at the second furnace ('RF2') to reach full production during 2020.  The Board is confident about the demand fundamentals of antimony and looks forward to the ramp up and commercial sales. The gold recovery circuit is now also proven and operational.  To date gold concentration in the alloy production remains at testing rather than commercial levels.  As levels increase, the production will be refined further in order to produce commercial grade gold dore.  This opens up a dual revenue stream opportunity for SPMP.
