The 2,500-metre program within the northern Diamba Sud block (DS1) started last week testing the high priority Northern Arc and Western Flank gold targets and is expected to be completed by early July before the onset of the wet season.
Chesser's managing director Mike Brown said: “We are highly encouraged by the quality of the bedrock gold targets identified from the phase I program.
“The current phase of drilling is seeking to confirm the controls to the widespread, high-grade gold mineralisation intersected to date.
“Importantly the geological attributes of these targets are considered very similar to the nearby world-class deposits associated with the Senegal-Mali Shear Zone (SMSZ).”

The phase II program will test for strike extensions to the interpreted north-trending Northern Arc target by drilling east-west lines to the north and south of the substantial intersections recorded in the phase I program.
Previous drilling was oriented perpendicular to the north-east trending gold auger geochemical anomaly.
At the Western Flank target, further drilling along east-west oriented lines will continue to evaluate the potential for a NNW trending mineralised structure.
The RC holes are planned to reach depths between 100 and 120 metres with at least one deeper diamond drill hole expected to be completed to gain a better insight into the geology and structural controls of the mineralisation.

Both targets exhibit similar geological characteristics to other large gold systems in the region, such as the nearby world-class Gounkoto/Loulou and Fekola gold deposits including:
- Spatially related to splays extending from the SMSZ;
- Northerly trend of mineralisation; and
- High-grade gold mineralisation associated with pyrite and strong alteration
