Hexagon Energy Materials Limited (ASX: HXG) has identified a number of follow-up targets with the completion of a significant airborne electromagnetic (AEM) survey at its Halls Creek project in the East Kimberley region of Western Australia.
Initial interpretation of preliminary data received to date has identified five high priority targets, each being late time anomalies with short strike length making them prospective for conductive massive sulphide mineralisation.
Chairman, Charles Whitfield, said a comprehensive interpretation will be undertaken upon receipt of the final data set (expected Q3 2021), with further high, moderate and lower priority anomalies to be assessed in detail.
We are thrilled with the preliminary results coming out of our Halls Creek AEM survey,” Mr Whitfield said.
“The five new targets together with the drill ready targets we had previously identified at Halls Creek Project enhance the Project’s prospectivity.
“We fully expect the new anomalies to attract the attention of potential partners. Hexagon’s pledge to get recognition of value for legacy projects continues to bear fruit and these results will add to the compelling case for the project in any discussions with potential partners or project developers.
“We look forward to further good news coming out of the work still being done by consultants at both the Halls Creek and at McIntosh projects, including field inspection of the newly identified AEM targets and the ground-based IP survey recently completed at the Lady Helen, Granite and Bent Ridge.
“The results of this work are expected to come through shortly. We also expect to soon update investors on results from continuing field activities at the McIntosh Project. While this work at both Halls Creek and McIntosh is being completed by external consultants, our core team is fully focussed on progressing the Prefeasibility Study at our flagship Pedirka Blue Hydrogen Project in the Northern Territory, with some of the formative work already complete.”
The helicopter-borne Versatile Time-Domain Electromagnetic (VTEM Max) system was flown by UTS Geophysics (Geotech) on 200m line spacing. It surveyed approximately 1,248 line-kilometres, spread over three areas totalling 242 sq. km.
The survey was designed to target potential Volcanic Massive Sulphide (VMS) style mineralisation within the Kongie Park Formation Project. The mineralisation was highlighted in a detailed aero magnetic survey undertaken by Hexagon in 2019, including Tiger, Sophie Downs and Five Mile Bore.
Work has commenced, with input from SGC, on follow-up surface EM (MELM) surveys across each of the high priority targets. This additional work will be undertaken subject to geophysical crew availability and in conjunction with surface geochemical sampling and geological mapping, prior to drill testing.
A 3D Induced Polarisation (IP) survey was also completed over the last weekend at Lady Helen, Granite and Bent Ridge prospects. The results from this survey will be used to aid in finalising drill program design at Bent Ridge and to refine drill targets at the remaining prospects.
