Summit has put boots on the ground at its Windfall antimony project in New South Wales with the start of fieldwork aimed at confirming prospectivity and guiding future work.

The field program includes accessing and sampling some of the historical workings from the Munga Creek camp, which was last operational in 1974 after producing over 1,100t of antimony.

It follows Summit Minerals (ASX:SUM) reaching new land access agreements across the Munga Creek workings, which will support its goal of delineating JORC resources at several historical antimony camps – including Pinnacles and Toorooka – that are located within the Windfall project.

Antimony is a silvery, brittle metalloid valued for its anti-corrosion properties which strengthen everything from nuclear energy facilities to batteries and wind turbines.

It is also used in the defence sector and in high tech devices like smartphones, semiconductors, cars and computers.

Summit adds that there is also growing awareness of its potential role in the next generation of large-capacity stationary batteries, which is supported by ongoing strength in the global antimony price.

“The historic Munga Creek mining centre is spread over 1.5km north to south and 900m east to west, with large gaps up to 300m between some of the 11 artisanal mines present,” managing director Jonathan King said.

“These areas have not been explored for decades, leaving swathes of untested opportunities between known antimony producing sites.

“We are excited to be on the ground and look forward to progressing these targets to drill-ready status in the first half of next year.”

Munga Creek

Antimony occurrences in Munga Creek are vein-type deposits of quartz and stibnite with breccia features commonly observed that are aligned along northerly trends.

Their distribution is invariably controlled by significant fault zones and fracture systems that have accommodated hydrothermal solutions though the source of mineralisation here remains unidentified.

An early ‘70s prospectus described the mineralisation as including “both narrow zones of ‘very high’ grade ore and wider and more laterally continuous lodes of lower but ‘probably’ still commercial grade.”

With much of this likely to still be true due to the dearth of work carried out on the area, Summit is keen to start working to define the project’s prospectivity and improve its understanding of what makes it tick.

Additional mapping, rock chip and preliminary soil sampling will be conducted over the coming months to identify priority target areas, which are expected to be drill tested next year upon drilling access permissions being received.
