The survey covered 200 square kilometres and the final data compilation is expected by early November.
Notably, preliminary data indicates significantly improved resolution and the presence of subtle detail that will allow more efficient and effective assessment and testing of targets.

Rimfire’s CEO John Kaminsky said: “This gravity survey should enhance our other recent work completed in mapping, sampling and magnetic geophysics reviews in the Southern and Central areas reported (ASX 3rd July 2018: Fieldwork in the Southern Project Area Highlights Gold Potential).
“The additional selected areas surveyed around Sorpresa, including the Fortuna gold anomaly to the north, and areas to the south-west, should both benefit from the gravity survey.
“This looks interesting, particularly as we know that the historic gravity has a good correlation with the Sorpresa mineralisation.
Preliminary survey data looks encouraging
“The preliminary survey data definitely looks encouraging and is providing greater insights than the publicly available low-resolution regional gravity data.
“Finalising the data compilation, integration and interpretation will be important in prioritising the next steps in these exciting surveyed areas and should further advance the implementation of the company’s strategic pursuits of new discoveries within the Fifield Project.”
Rimfire's major focus is its Fifield Project where it discovered the Sorpresa gold-silver deposit, revealing a maiden resource in 2014.
Since then, multiple prospects involving hard rock potential for gold, silver, copper and platinum have been established within a 6-kilometre radius from Sorpresa.
