Rimfire Pacific Mining NL [ASX:RIM] - Excellent Preliminary Metallurgy Results at Sorpresa, Fifield NSW

Rimfire Pacific Mining NL (ASX:RIM) (�Rimfire� or �The Company�) is pleased to provide results on recent metallurgical test work for the Sorpresa Gold and Silver project at Fifield in central NSW.

Highlights:

� The best Gold recovery was 96.8%, occurring at the Trench 31 location
� Roadside location achieved a recovery high of 84.3% for Gold and 68.9% for Silver, which were improved with finer grind and longer leach time to 89.1% and 72.3% respectively
� Testing focused on a wide representation of oxide mineralization from 3 locations at Sorpresa using Carbon In Leach (CIL), standard method

A series of preliminary metallurgical tests have been conducted on Fifield samples by a NATA registered laboratory (ALS Metallurgy) in Sydney, under the direction and supervision of contract metallurgist of some 40 years experience, Mr. David Foster.

The testwork was conducted on three composite samples from the Roadside, Trench 31 and Trench 31 South West locations within the Sorpresa project area.

Samples were selected to give a wide representation of the mineralization in the 0 � 45 metre oxide zone and comprised a total of 130 metres of mineralization from 30 drill holes within the 1.6km strike line of the Sorpresa project area, in three distinct locations (see Appendix 1 from the link).

�The metallurgical testwork was conducted on an extensive and diverse spread of mineralized material at Sorpresa. The high recovery figures are most encouraging as the samples are representative for all the important oxide zones seen to date,� executive chairman John Kaminsky said.
