Rimfire Pacific Mining (ASX:RIM) will resample historic drill core to confirm the gold and antimony potential of the Windy Ridge prospect in New South Wales, after rock chip sampling, IP geophysics, and drilling undertaken 40 years ago defined a 2.5-kilometre-long gold prospective corridor at Windy Ridge, which lies some 30 kilometres southwest of Broken Hill.

Rimfire’s managing director, David Hutton, today said historic exploration found the strongest gold and antimony grades were present within a 600 metre long zone at the northern end of the prospect.
“40 years after Windy Ridge was last drilled, and we have been able to locate and resample two of the original diamond drill holes to confirm the historic gold drill intercepts and levels of antimony associated with the gold,” he said.
“Significantly, we were also able to confirm the accuracy of the geological drill logs and the presence of sulphide mineralisation (arsenopyrite and pyrite) within prospective rocks.”
He said that the confirmation of antimony at Windy Ridge will strengthen the attractiveness of the company’s Broken Hill base metals project. The value of antimony continues to grow at a time when the Australian government is ramping up a new $1.2 billion Critical Minerals Strategic Reserve
“With our high-value Fifield scandium assets and an emerging precious metals and critical minerals opportunity at Broken Hill, Rimfire is perfectly positioned to leverage the growing appetite for these in-demand minerals,” Mr Hutton said.
Windy Ridge occurs in the same rock sequence that hosts the Broken Hill line of lode silver-lead-zinc deposits. Mineralisation remains open down dip with multiple drill intercepts returned from the original drilling.
RIM ended at 1.7c on Tuesday. Mkt cap 47.02M.
