Rimfire Pacific Mining (ASX: RIM) has completed diamond and reverse circulation drilling at its Sorpresa gold project in New South Wales with mineralisation encountered in most holes.
All five of the diamond holes intersected mineralisation with some geological consistency noted, indicating the mineralised system is likely continuous and large scale.
Core orientation for structure determination will take a further two weeks, with priority intervals to be finalised and sampled for laboratory assay.
Petrological assessment is being carried out on the cores to assist in the understanding of the characteristics of the various geological components of the Sorpresa mineralisation.
The fifth hole was taken to a depth of about 500 metres to gain further context of the stratigraphy and geology at Sorpresa. The hole is considered to provide guidance on the important geological changes noted in the southeast direction from the other preceding diamond holes.
Many holes in the 38 holes reverse circulation program appear mineralised based on handheld XRF analysis and assays for the program are expected within the next three weeks or so.
Rimfire is also continuing its rotary air blast drilling program to the southwest of the known gold mineralized position at Trench 31 location where much of the highly prospective Sorpresa Project Area has not been explored and is concealed under shallow alluvium.
The company has completed 125 drill holes to shallow depths to date and has identified mineralised bedrock.
Relevant geology appears present including “black silica”, doubling the known area of this important rock type and geochemistry assays will be compiled for the bedrock and used as a basis for deciding deeper reconnaissance drilling to be conducted at a later stage.
