Drilling extends gold mineralisation at Chesser’s Diamba Sud project

Special Report: Chesser has grown the scale of its Diamba Sud project in Senegal after extensional drilling intersected high-grade gold.
Top results include 6m at 5.6 grams per tonne (g/t) gold from 110m and 6m at 5.44g/t gold from 96m in the same hole at the Eastern structure and 15m at 3.39g/t gold from 117m and ending in mineralisation at the Western structure.
Hits above 5g/t gold are generally considered to be high-grade.
Chesser Resources (ASX:CHZ) says the results identify and confirm the two high-grade gold structures over a 250m strike length.
Diamba Sud is right next door to Barrick’s Bambadji joint venture with IAMGOLD and sits within prolific but underexplored Senegal-Mali Shear Zone, which hosts giant mines such as the 18 million ounce (Moz) Loulo-Gounkoto mine and the 7.6Moz Fekola mine.
In addition, drilling within the existing Area A footprint has also returned high-grade intercepts including 4m at 10.67g/t gold within a broader zone of 12m at 3.86g/t gold from 14m, 8m grading 6.81g/t gold from 95m and 4m at 7.35g/t gold from 80m.
A further two drill lines testing the southeast extension of Area A have also intersected alteration and sulphides in the host structure towards the Bambadji JV.
“These new results continue to grow the scale and improve our understanding of the structural controls of this significant gold discovery,” managing director Mike Brown said.
Further assay results are pending from the Western Splay target, Area D, the anomaly located between Area A and D, the additional holes planned at Area A and a line of holes on the southeast extension of Area A near the tenement boundary.
Chesser first discovered Area A in 2019 after carrying out auger drilling to define the anomaly.
Initial results had delivered shallow, thick and high-grade results such as 18m at 5.61g/t gold from 6m and 21m at 6.62g/t gold from 53m.
