Laboratory testing by Lindian Resources confirms high-grade alumina at Gaoual Project

Lindian Resources Limited has reportedly confirmed that laboratory testing of extensions to the Bouba conglomerate bauxite plateau within the Gaoual Project has discovered high-grade alumina averaging more than 50 per cent.

Earlier this year, resource drilling along the Bouba Plateau had confirmed the presence of very high-grade conglomerate bauxite. Further drilling was undertaken at Bouba North and Bouba South using a portable X-ray fluorescent (XRF) reader to determine alumina grade.

Northern and southern extensions at the Bouba Plateau were discovered later in March.

Three drill holes at Bouba North recovered average alumina grades of 50-54.4 per cent, while four holes at Bouba South found more than 54 per cent alumina with the highest average grade being 58.5 per cent.

Lindian said digestion tests would be conducted on selective samples in the weeks to come to determine the silica classification and the recovery performance of the material at low and high temperatures.

 “The extensions will no doubt add considerable scale to the very high-grade conglomerate bauxite, further strengthening the significance of the Bouba Plateau and the entire project area, leaving no doubt this is a world-class discovery,” the company stated.

According to Lindian, the latest results of laboratory testing also confirmed that although the project’s resource has grown from the primary resource as defined in the first set of assays, the appearance of the resource is yet to alter in grade or quality.

The company is planning to release JORC-compliant resource statement after the final digestion work is complete.

“Confirmation from the independent geological expert that we are on track to deliver our inaugural JORC-compliant resource statement before mid-year is a significant step towards the development of this incredible project,” said Lindian managing director Shannon Green.
