Cosmo Metals (ASX:CMO) reports up to 10.3% Sb from Antimony Gully surface sampling at Bingara Project

Cosmo Metals has reported results from surface mapping and sampling completed across historic antimony workings within the +8km Antimony Gully Trend at the Bingara Project in New South Wales.

The work covered the Plunkett & Cassidy, Evans & Corrigan and McManus prospect areas within the Bingara Project, which covers approximately 484.1 km² in the New England Orogen.

Highlights

• Surface mapping and rock chip sampling completed across historic antimony workings within the +8km Antimony Gully Trend
• Plunkett & Cassidy area identified sub parallel lines of lode separated by more than 100m with strike lengths up to 1.17km
• Rock chip sampling returned results up to 10.3% Sb and 5.37% Sb from quartz vein breccias containing visible antimony sulphide (stibnite)
• McManus area includes a 360m line of historic workings with previous rock chip results up to 5.75% Sb
• Evans & Corrigan area recorded limited surface exposure due to farming activity
• Follow up work will include soil geochemical sampling and detailed geological mapping

Cosmo Metals reports that mapping and sampling were completed across clusters of historic antimony workings within the Antimony Gully Trend.

The trend is described in the announcement as extending over approximately 8km and is associated with historic pits, workings and quartz vein breccia occurrences within the Bingara Project area.

At the Plunkett & Cassidy prospect area, field mapping identified sub parallel lines of lode separated by more than 100m, with strike continuity of up to approximately 1.17km.

Rock chip sampling from this area returned results up to 10.3% Sb and 5.37% Sb from quartz vein breccias, with visible antimony sulphide (stibnite) reported in sample descriptions, and the mapped material comprising oxidised quartz breccia float, subcrop and historic workings.

At the McManus prospect area, reconnaissance sampling identified a line of historic workings extending approximately 360m, with previous rock chip results returning values up to 5.75% Sb from quartz vein breccia material reported from mine dumps.

At the Evans & Corrigan area, mapping recorded limited surface exposure of mineralised material, with historic workings largely obscured by farming activity, and the announcement notes that quartz mineralisation outside the main mapped trend is limited in this area.

The company reports that LiDAR data collected across the Bingara Project was used to assist mapping and interpretation of surface features and historic workings.

The dataset covers the full 484.1 km² project area and was used alongside field mapping to identify locations of historic pits, workings and quartz vein breccia outcrops.

Cosmo managing director Ian Prentice stated in the announcement that

“the recent on ground mapping and surface sampling at the +8km long Antimony Gully Trend has highlighted this area’s prospectivity for large scale antimony gold mineralisation, particularly at the Plunkett and Cassidy prospect, with its +1km strike extent and potential for multiple parallel shoots over 100’s of metres.”

The announcement states that follow up work will include soil geochemical sampling using mechanised auger techniques in areas affected by farming activity, together with detailed geological mapping, with the purpose of this work stated as identifying and prioritising targets for future exploration.

Cosmo Metals confirms that results reported are based on surface sampling and mapping. No drilling is included in the current program.

All assay results referenced are from rock chip and selective sampling as disclosed in the ASX release.
