Mamba Exploration Limited announced that auger drilling completed in late 2021 at the Ashburton Gold Project in Western Australia has identified a base of transported cover gold anomaly which extends for approximately 300m by 200m at the Bettina Prospect at Lyndon. The anomaly includes gold anomalism of up to 36ppb gold, which is more than 15 times the background gold level of around 2 ppb gold. The historical rock chip sampling within the workings identified a number of high-grade quartz veins with grades up to 46.5 g/t gold and 4m @ 21.5 g/t gold in historical RC drilling.

Mamba has rock chip sampled a number of the quartz veins in the workings and confirmed the mineralisation with grades of up to 36.5 g/t gold identified. Sampling of the waste dump also identified high grade mineralisation of up to 17.6 g/t gold. As a result of the size and strength of the anomaly, a programme of works has been submitted to the department of Mines Industry Regulation and Safety and approval received for RC drilling.

The detailed planning for the drilling is underway, however, given the higher priority drill targets that have been identified at the Company's Calyerup Creek Gold Project, drilling of this anomaly is not expected to be undertaken until mid-2022. An auger programme was also undertaken at the Osbourne Well tenement, testing a large regional structure. This auger sampling confirmed a small 26ppb gold anomaly at the Woods Prospect and a number of other very low order anomalies associated with the regional structure, however no significant anomaly was identified.
