SVL identifies potential new calderas for silver at Bowdens Silver Project, NSW

Project Name: Bowdens Silver Project
Project Location: NSW, Australia
Project Stage: Advanced Exploration

ProjectBank Summary:
Silver Mines Limited (ASX: SVL) has announced the identification of multiple new caldera structures within the Bowdens District following the completion of a major 2D seismic surveying program. The survey, which covered nearly 96 kilometres, highlighted five separate calderas, three within the Bowdens Caldera (Bowdens Volcanic Complex) and two within the Coomber Volcanic Complex. These findings significantly enhance the exploration potential of the Bowdens Silver Deposit, which hosts a 396Moz AgEq Bowdens Silver deposit. The company plans to focus exploration activities on these newly modelled calderas, including Bara Creek, Three Hills, and Coomber calderas, among others. Detailed follow-up work is expected to further delineate these targets and support ongoing exploration efforts.

Silver Mines Highlights:

• Exploration of the Bowdens district has been significantly enhanced with the completion of a major seismic surveying program.

• Interpretation of the 2D seismic survey has highlighted multiple new caldera structures within the Rylstone Volcanics, analogous to that which hosts the 396Moz AgEq Bowdens Silver deposit.

• Exploration activities will now focus on the five separate calderas modelled – three within the Bowdens Caldera (Bowdens Volcanic Complex), and two calderas within the Coomber Volcanic Complex (including the Coomber Prospect and to the north of Rylstone).

  • Bara Creek caldera is 4km by 4km and appears preserved by silicification.

  • Three Hills caldera is 3.5km by 3.5km and completely covered by Sydney Basin sediments.

  • Coomber caldera is 3.3km by 3.3km and has silver-zinc-lead-gold mineralisation discovered by CRA Exploration in 1991.

  • Armentum caldera roughly 5.6km by 4.1km and predominantly covered by Sydney Basin sediments.

• The regional model is driven by multiple high-quality data sources and industry collaborations with the Mineral Systems team at NSW Mining, Exploration & Geoscience (MEG) and research through the University of NSW.

MD/CEO Statement:
Jonathan Battershill, Managing Director, commented: "The identification of these new caldera structures is a significant advancement for our exploration program at Bowdens. These findings open up new opportunities for discovering additional high-grade mineralisation and demonstrate the extensive potential of the Bowdens district. We are excited to pursue these new targets and continue our work to unlock the full value of this prolific region."
