Mamba Exploration Limited (ASX:M24) has commenced a detailed gravity survey over the regional gravity anomaly directly east of the historical high-grade clay hosted REE mineralization and commenced initial drilling around the high grade clay hosted REE mineralization identified from historical exploration in Western Australia.
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 mineralization 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 mineralization to better understand the potential and source of the very high-grade clay mineralization.
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.
“We are pleased to report that the ground based gravity survey over the high priority regional gravity anomaly identified directly east of the very high grade clay hosted REE mineralization has commenced,” Managing Director Mike Dunbar said.
“The survey has been designed to better define the anomaly with the aim to provide a direct drill targeting tool for bedrock REE mineralization.
“In addition to the ground gravity survey, initial drilling around the very high-grade (4.67% TREO) mineralization identified from the very limited historical REE exploration has commenced. The initial drill programme of 20 holes has been planned to confirm the historical mineralization and provide a better understanding of the source of the very high grades identified.
“Both the gravity and initial drill programmes are expected to be completed in the next week with the assay results from the drilling expected to be received in mid to late February and the gravity modelling results expected by the end of January.”
