Rimfire Pacific Mining NL [ASX:RIM] - Exploration Update from Rimfire Pacific�s Sorpresa Gold and Silver project at Fifield NSW

Rimfire Pacific Mining (ASX: RIM) has updated shareholders with its latest Exploration Presentation covering the company�s activities at its major project at Fifield in central NSW, located within the Lachlan-Cadia Lineament.

The last 12 months has seen an expansion of the Sorpresa Gold and Silver project area at Fifield and the Company has also laid a platform for discovery growth in the wider district. Rimfire Pacific has built solidly on earlier exploration success at Sorpresa during 2013, particularly the strong silver expression shown at the Roadside location, where much of the Company�s effort has been expended recently. High grades for gold and silver were again encountered at Sorpresa in 2013, including bonanza grade:

� Fi 329 DDH - 1m @ 114g/t Au from 159m Plus 1m @ 33g/t Ag
� Fi 241 - 10m @ 535g/t Ag from 70m (incl. 2m @ 2020g/t Ag) Plus 10m @ 1.0g/t Au
� Fi 287 - 4m @ 21.9g/t Au from 38m

These results were spread across a large area re-affirming the view that the potential for high grade continues, with the more work that is done. The exploration capability has been greatly enhanced recently with the commencement of Darren Glover as Exploration and Development Manager, and further geological field personnel also added at Fifield. This builds upon the excellent foundation established by Colin Plumridge and provides additional expertise to a project area that has grown substantially from the discovery period in 2010.

Additional detail of the exploration program is also included in the Company�s Exploration Presentation available on the website:

The exploration work conducted at Sorpresa and the surrounding district at Fifield has now established further key milestones during the last 12 months, including:

� Diamond drill program conducted midyear provided major positive insights to the district potential
� No firm geological limits exist to the �Greater Sorpresa� field size � it has extensive room to grow
� Similarities are emerging with the �Carbonate Base Metal Epithermal Gold Mineralization Model� which is very well credentialed, and includes Lake Cowal and Porgera as successful examples of operating mines
� An advancement in the platinum geology understanding has occurred

� Continued Intersections of high grade gold and silver values, suggesting such grades are not rare

� The �receptive horizon� host geology of Sorpresa is approx. 1.7km strike x 0.4km and open

� 3D shapes of the various parts of the Sorpresa mineralization are being modelled moving towards resource definition as discovery extension grows.
� The most recent rounds of drilling and follow up drilling planned will provide valuable input to progress and timing in this regard

� The Greater Sorpresa area is estimated at 8km2 , contains multiple mineralization targets being advanced
� RAB drilling has doubled the relevant host geology to the South West of Trench 31

� Strong correlations to geophysics (particularly IP and gravity) is assisting mineralization targeting

� A positive environmental permitting record providing a clear path for further work to proceed

Whilst Fifield is historically recognised as Australias largest dedicated Platinum producing area 120 years ago, the Company has now established multiple project areas of importance involving hard rock Gold (Au), Silver (Ag), Platinum (Pt) and Base Metal within an extensive prospective 20km2 area at Fifield.
