BlackEarth Minerals NL (ASX: BEM) (“BlackEarth”, the “Company”), a company specialising in critical commodities, is pleased to announce the commencement of a regional scale, detailed airborne electromagnetic (AEM) at its 100% owned Donnelly River Nickel-Copper-Platinum Group Metals (Ni-CuPGM) Project located 240km south of Perth, Western Australia.
The Donnelly River Project is situated immediately adjoining the Thor and Odin Ni-Cu-PGM Prospects, recently identified by Chalice Gold Mines and Venture Minerals at their South West JV.
Key details of the survey include:
The AEM survey has identified a number of significant conductors that warrant more detailed assessment and testing. The data management and interpretation of the survey was undertaken by Southern Geoscience Consultants (SGC):
Targets 1 and 2 are considered high priority VTEM targets based on their high-amplitude, late-time conductance. Both are coincident with magnetic trends that potentially represent the targeted mafic-ultramafic rock types (Figure 1).
Target 4 is of particular interest even though it is only ranked as a moderate VTEM conductor as it is located within the geochemically anomalous, mapped mafic-ultramafic units identified at the Palgorup Prospect.
Targets 5 and 6 are moderate VTEM conductors but their proximity to prospective magnetic trends, interpreted as potential mafic-ultramafic units, elevate their priority
The results of this survey have now provided areas of key focus within the broader Donnelly River Project. Each target will be assessed in detail and follow-up programs of ground-based exploration will be designed and implemented subject to standard ground access protocols.
The survey was completed by UTS Geophysics using a VTEM Max Versatile Time Domain
The survey covered the entirety of E70/4825 (~80km2 ) and was flown on 200m line spacing for a total of 396-line kilometres.
