CONDUCTORS IDENTIFIED IN AIRBORNE GEOPHYSICAL SURVEY AT DONNELLY RIVER

BlackEarth Minerals NL (ASX: BEM)

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

  • Electromagnetic System.

  • The survey covered the entirety of E70/4825 (~80km2 ) and was flown on 200m line spacing for a total of 396-line kilometres.
