Airborne Magnetic Survey Underway In Western Australia
Alien Metals Ltd (AIM:UFO) has commenced an airborne magnetic survey over the Elizabeth Hill Project in Western Australia.
The Project not only covers the original Mining Licence M47/342 which hosts the Elizabeth Hill Silver Mine and associated prospects, but also exploration permit ELA47/4422, which the Company has conditionally acquired and will be referred to as the Munni Munni North tenement going forward, a name used for part of this area in the past.
CEO and Technical Director, Bill Brodie, said the aeromagnetic survey will aid in tying in all existing prospects and historical data to assist in prioritising numerous existing targets
The company is also looking for potential new targets with a collation of the airborne surveys, geological interpretations and geochemical results, to generate new options across Munni Munni North
Alien has engaged Southern Geoscience Consultants (SGC) of Perth, WA, to provide and manage the acquisition, processing and interpretation of airborne magnetic, radiometric and digital elevation data over the Elizabeth Hill Project.
From a detailed review of existing available data it was decided to only fly the eastern section of the project area as the western area was recently flown at the same line spacing and line direction with that data available to purchase at less than the cost of re-flying it.
SGC have confirmed that they can integrate both data sets into one larger unit that they can then interpret as a single area.
“The company is extremely pleased that we can announce the commencement of this program as it will add invaluable overall new interpretation to the entire project area and allow us to incorporate various historic results with this new data,” Mr Brodie said.
“We are delighted to get this work underway at this time so over the coming weeks while field work is much more limited due to the cyclone season in the region the team can keep working in the background.
“Once we have the results and interpretations we can start developing priority targets to follow up in the field alongside the already planned trenching within the Mining Licence.
“The company is excited about the potential to add significant value to the project and developing next stage exploration from the outcome and looks forward to updating the market of progress in due course
Thomson Airborne Pty Ltd of New South Wales are carrying out the acquisition work and are due to commence today using a Cessna 210 fixed wing aircraft. They will be flying @ 1,534 line km to cover the survey area at 50m spaced east west lines with north south ‘tie’ lines.
Once this data has been collected and verified SGC will integrate it with the existing high quality data for the western area that is already flown and then complete a geological and structural interpretation based on 1:25,000 scale.
Processing of the new data would entail survey planning and contractor communication, gridding and levelling (if required) of the magnetic, radiometric and digital terrain data and grid filtering, image processing and enhancement (TMI, TMI1VD, Analytic Signal, RTP, RTP1VD, RTP2VD, RTPTilt, ASVI, DEM, TC, K, U, Th) using a relevant sun angle of this data. Along with this work SGC will also re-process and merge the existing multi-client survey dataset to make one large dataset for interpretation.
A comprehensive interpretation of the aeromagnetic data would integrate all relevant geoscientific information, allowing for the mapping of lithologies and structure. The regional aeromagnetic data would be referred to, if required, to assist in understanding any broader scale features beyond the tenement area.
The company plans to have the final results and interpretations mid to late February 2021 to be able to start planning the follow up field work going into the optimal field season in the region.
