Mantle Minerals completed its maiden aircore drilling program at the Mt Berghaus gold exploration tenements E47/4531 and E45/5899.

The company drilled a total of 7,357m across 126 holes. Assays from the drilling are expected to be received in July.

The drilling program aimed to test the intersections of interpreted geological structures and stratigraphy that could be related to De Grey Mining's (ASX: DEG) Hemi deposit, which lies immediately to the south of Mantle's tenements.

Follow-up reverse circulation drilling is planned to target deeper levels, where higher-grade gold mineralisation is expected, similar to the discovery method of Hemi.
