Ann: New Resource Estimation for Paguanta, page-2

NEW RESOURCE ESTIMATION FOR PAGUANTA  JORC 2012 Mineral Resource estimate for the Patricia deposit of 2.4Mt at 5.0% zinc, 1.4% lead, 88 g/t silver and 0.3 g/t gold (or 2.4Mt at 8.0% zinc equivalent).  Almost 50% of the resource in the Measured and Indicated categories.  190,000 tonnes of contained zinc equivalent (Zn Eq) metal.  Resource remains open at depth and along strike to the south east.  Steeply plunging high-grade ore shoots are evident in the resource.  Recent deep diamond hole (PTTDD-17-136) has returned a very high grade intercept of 0.75m at 12% zinc, 7.5% lead, 1,765 g/t silver and 1.7 g/t gold (526.9m to 527.65m) amongst several other wider intercepts in one of these shoot locations.  Infill drilling to test significant voids in the new resource being planned, with a further updated resource estimate to be delivered by the end of 2017.  The Company will consider extensional drilling down plunge of the high-grade shoots. Golden Rim Resources Ltd (ASX: GMR) (Golden Rim, Company) advises that it has updated the Mineral Resource estimate for the Patricia Zinc-Silver-Lead deposit (Patricia) at the Paguanta Project (Paguanta) in Chile. Golden Rim’s Managing Director, Craig Mackay, said “We are pleased with the outcome of the recent drilling program which has helped deliver a robust JORC 2012 resource estimate for Patricia. The new resource provides us with a much improved understanding of the geometry, grade distribution and continuity of the significant zinc-silver-lead-gold mineralisation and provides the Company with a sound basis for moving forward.” “There are large gaps in the drilling at Patricia which has resulted in voids in the new resource, particularly in areas where substantial additional mineralisation was recently discovered by Golden Rim. Further, the resource remains open at depth and along strike.” “We believe further infill drilling and extensional drilling focussed on improving the overall grade will provide us with a solid increase to the tonnes and grade of the Mineral Resource before the end of 2017” said Mr Mackay. The resource estimate, based on historical data and Golden Rim’s recently completed seven hole (3,189m) diamond drilling program, was independently completed by Mining One Consultants (Mining One). The results of Golden Rim’s 13 hole (3,462m) Reverse Circulation (RC) drilling program, which remaining pending, have not been included in the updated resource estimate.
