Rimfire Pacific Mining is an ASX listed (code: RIM) resources exploration company that has its major emphasis focused at Fifield in central western NSW.

Rimfire operates a large and contiguous 669km2 tenement package located within the East Lachlan Fold Belt (ELFB) of NSW, traversed by the crustal scale Lachlan Transverse Zone (LTZ) upon which most of the world class deposits in the ELFB are associated.
In 2010 the Company delivered a greenfields gold and silver discovery, named “Sorpresa”, in the Fifield district. A maiden JORC 2012 compliant resource of 6.4Mt @ 0.61g/t Au and 38g/t Ag for 125kOz Au and 7.9Moz Ag was delivered in December 2014. Subsequent exploration has provided evidence that the “wider Sorpresa area” is now considered a significant gold mineralized district of some promise. The gold is predominantly native gold.
The current main Sorpresa Strike line containing gold and silver mineralization is approximately 1.5km in length and is at various stages of further resource extension and discovery growth drilling.
The Company has now established multiple project areas of importance involving hard rock Gold (Au), Silver (Ag), Copper (Cu) and Platinum (Pt) within a 6km radius of the Sorpresa discovery covering an extensive prospective 35kmarea at Fifield, which is part of the contiguous 669km2 tenement position held.
The Company has been committed to pursue a prospect portfolio strategy of developing the regional prospects at Fifield to suitable stages, in parallel with the Sorpresa project area to achieve outcomes as follows:
  • Enhance and highlight the Fifield district’s mineralisation potential and appeal 
  • Deliver more discoveries in the district including within 6km radius of Sorpresa
  • Metals to be pursued include Gold, Silver, Copper and Platinum 
  • Manage and continually assess the more than 30 prospects in its exploration portfolio
  • Continue discovery and resource growth at Sorpresa , whilst assessing its economic potential
  • Work collaboratively with Canadian partner New Gold Inc. to accelerate discovery outcomes in the project areas.
