BlackEarth Minerals’ AEM survey outlines major targets at Donnelly River

Summary

  • BlackEarth has identified significant conductors in an airborne electromagnetic survey at its Donnelly River Project in Western Australia. 
  • The survey was flown on a 200-metre line spacing for a total of 396-line kilometres. 
  • The survey, which delivered key focus areas within the broader project, is expected to underpin follow-up programs of ground-based exploration. 

BlackEarth Minerals NL (ASX: BEM) is on a fast-paced growth track, thanks to the Company’s steady stream of activities aimed at cementing its position in the diverse commodity space.

In what bodes well for its growth objectives, BlackEarth has shared an encouraging update from a detailed, regional-scale airborne electromagnetic (AEM) survey at its Donnelly River Project in Western Australia. 

The 100%-owned project sits 240 kilometres south of Perth and hosts nickel (Ni), Copper (Cu) and Platinum Group Metals (PGM). The project is situated immediately adjoining the Thor and Odin Ni-Cu-PGM prospects, which have been recently identified by Chalice Gold Mines and Venture Minerals at their South West Project.

Significant conductors identified for further assessment and testing

Southern Geoscience Consultants undertook the data management and interpretation of the AEM survey, which identified several significant conductors, warranting more detailed assessment and testing.

High priority VTEM targets

Targets 1 and 2 are ranked as the high priority VTEM targets based on their late-time conductance and high amplitude. Both the targets are coincident with magnetic trends, potentially representing the targeted mafic-ultramafic rock types. 

Moderate VTEM conductors

Although Target 4 is considered a moderate VTEM conductor, it is of particular interest as it is situated within the geochemically anomalous, mapped mafic-ultramafic units identified at the Palgorup prospect. 

Other moderate VTEM conductors include Targets 5 and 6, which have significant priority owing to their proximity to prospective magnetic trends interpreted as potential mafic-ultramafic units.

AEM survey to facilitate the ground-based exploration

The AEM survey covering the whole of E70/4825 (around 80 square kilometres) was flown on a 200-metre line spacing for 396-line kilometres. UTS Geophysics completed the AEM survey, utilising a VTEM Max Versatile Time Domain Electromagnetic System. 

The survey results have identified the key focus areas within the broader Donnelly River project. The Company intends to assess each target in detail as well as design and implement follow-up programs of ground-based exploration, subject to standard ground access protocols.

Management Comment

Hailing the survey results as “exciting”, BlackEarth Managing Director Tom Revy stated that while the Donnelly River Prospect was in a very early exploration stage, the identification of six follow-up VTEM targets coincident with mafic-ultramafic rocks or magnetic trends was very encouraging for BlackEarth. The recent development highlights potential resemblances to other Western Australia-based large-scale nickel sulphide discoveries. 

Mr Revy indicated that the Company’s management and the technical team would review further steps at Donnelly River to realise shareholders’ value promptly.
