The survey has revealed similarities of the Area A and Area D discoveries to intrusive related mineralisation at Barrick Gold Corp’s (TSE:ABX) 3 million ounces Massawa project, 50 kilometres to the west of Diamba Sud.
The high-grade gold mineralisation recently intersected at Area A correlates with a broad chargeability anomaly coincident with an interpreted granodioritic intrusive, indicating potential for the mineralisation to be more extensive.

Chesser has also revealed the results of a Gradient array induced polarisation (GAIP) survey over the Northern Arc and Western Flank targets:
- Two northerly trending interpreted structures passing through Area A and Area D high grade intersections;
- Northerly trends are the main structural trend hosting mineralisation at all of the tier 1 deposits on the Senegal-Mali Shear Zone (SMSZ); and
- Presence of the highly prospective Western Splay structure extending from the prolific Senegal-Mali Shear Zone (SMSZ) confirmed passing to the west of the Western Flank Target.

Chesser managing director and CEO Mike Brown said: “The IP survey results are very encouraging from two perspectives.
“The first is confirmation of a potential intrusive body associated with the Area A discovery. This is very encouraging in terms of the potential deposit style, noting Barrick’s nearby multi-million ounce, intrusion-related, Massawa gold project in Senegal.
“The second is the identification of at least three significant resistivity anomalies associated with potential structures passing through the Area A discovery, Area D and confirmation of the interpreted Western Splay structure.
“Two of these have returned significant high-grade intersections, are on the same trend as the mineralisation controlling structures in the SMSZ hosting over 45 million ounces of gold and are essentially untested along strike.
“We are currently incorporating this latest information into planning for our follow-up drilling programs, which we hope to commence in October, weather conditions permitting.”
Chesser is currently finalising preparation for the next phase of drilling, with clearing of access underway.
This program is expected to initially focus on testing for extensions and controls to the high-grade gold mineralisation at Area A and Area D, with about 2,000 metres of diamond drilling and 5,000 metres of RC drilling planned.
The recently announced successful capital raising is anticipated to cover the expected costs of these drilling programs.
