Mamba Exploration Limited announced that it has commenced a detailed gravity survey over the regional gravity anomaly directly east of the historical high-grade clay hosted REE mineralisation and commenced initial drilling around the high grade clay hosted REE mineralisation identified from historical exploration. As announced on the 28th of November 2022, Mamba has entered into an option agreement over the Hyden project where limited historical REE exploration identified up to 46,716 ppm TREO (4.67%) in clay from 12m downhole. The mineralisation was not properly sampled and remains open in all directions.

As a result, Mamba is undertaking a 20-hole aircore drilling programme as an initial test of the clay around the original mineralisation to better understand the potential and source of the very high grade clay mineralisation. The drill programme is underway and is expected to be completed in the next week. In addition to the initial drilling, a detailed gravity survey is underway to better define the regional gravity anomaly that was identified in the initial due diligence undertaken on the project.

Carbonatite hosted REE deposits are commonly associated with distinctive gravity anomalies, as a result the detailed survey has been planned to better define the regional anomaly and provide direct drill targets. This gravity survey is expected to be completed within a week with inversion modelling to be undertaken to define drill targets.
