By integrating the original drilling used in the 2014 resource estimate with more recent data, the company believes it could achieve a greater understanding of any potential value upside.
The successful identification of higher grade mineralisation zones would reframe the approach to further assessment of the Sorpresa deposit.
Rimfire’s CEO John Kaminsky said: “The company is moving forward with the dual strategy of pursuing the known Sorpresa gold and silver resource appraisal, including the immediate surrounds of Sorpresa for discovery extension, and the potential for discovery of large-scale gold and copper mineralisation in the region.
“Craig has added strong impetus and capability to both of these strategic objectives, and we are delighted with the progress and planning he has been able to bring to the project area so quickly.
“The additional funding sought in the recently announced rights issue (ASX 4 October 2018) will be well deployed pursuing these goals, and we look forward to providing further updates to shareholders.”
Work underway to assess Sorpresa, gravity results pending
The 2014 Sorpresa JORC estimate stands at 6.4 million tonnes grading 0.61 g/t gold and 38 g/t silver for 125,000 ounces of gold and 7.9 million ounces of silver.
Work is now in progress to identify potential higher grade zones.
Furthermore, a the detailed gravity survey at Fifield outlined in September has been complete and the data is being analysed so results can be released.
