Silver Mines Ltd (ASX:SVL, OTC:SLVMF) has leveraged a seismic survey carried out over the Bowdens Silver Deposit to identify several new potential Caldera structures within the Rylstone Volcanics belt, similar to those hosting the current 396-million-ounce silver resource on the project.
The company will now focus on five separate modelled Calderas, three within the Bowdens Caldera, and two within the Coomber Volcanic Complex, which also includes the Coomber prospect.
Four new silver-prospective Calderas
Apart from the core Bowdens Deposit Caldera, the company will also undertake exploration on the Three Hills, Bara Creek, Coomber and Armentum calderas.
Bara Creek is a 4-kilometre by 4-kilometre structure that Silver Mines believes was preserved by silicification (replacement of original rock by calcium and silica deposits) and limited historical exploration work identified a gold-copper-silver association in stream sediment samples.
Three Hills measures 3.5 kilometres by 3.5 kilometres and is completed covered by Sydney Basin sediments and remains completely untested.
Coomber covers a 3.3-kilometre by 3.3-kilometre area with historically-identified silver-zinc-lead-gold mineralisation – SVL believes Coomber has “significant” resource potential.
Finally, the Armentum Caldera is roughly 5.6 kilometres by 4.1 kilometres and is again covered by Sydney Basin sediments, unexplored to-date.
Silver Mines says the new regional model that identified these Caldera was based on multiple high-quality data sources and industry collaborations with the Mineral Systems team at NSW Mining, Exploration and Geoscience (MEG), as well as research through the University of NSW.
