Armada Metals Ltd (ASX:AMM) says modelling of its Mobile Magnetotellurics (MobileMT) datasets has picked out multiple preliminary targets consistent with the company’s regional mapping of the Nyanga Magmatic Nickel-Copper Project in Gabon.
Preliminary modelling of the airborne MobileMT survey data has defined multiple targets at the project, which will direct future ground-based NSAMT (survey) programs and drill targeting.
Multiple new targets
The survey’s objective was to assess the company's Libonga-Matchiti Trend and the Ngongo-Yoyo Trend with this latest technology and it has yielded a raft of additional targets.
A series of ground-based NSAMT surveys are planned to follow up on the highest priority targets in advance of further drilling. These new targets will be used to design future ground-based surveys.
The Mobile Magnetotellurics survey directly measured resistivities and was designed to detect the potential for apparent conductors.
The lowest resistivity values, ranging at less than 100-400 ohm-m, are considered significant by the technical team.
Armada managing director and CEO Dr Ross McGowan said: “We are delighted that the MobileMT survey has exceeded our expectations and achieved its objective of identifying a new generation of priority nickel-copper targets for ground-based follow-up and potential drill testing later in 2023.
“Importantly, the preliminary modelling represents a validation of our exploration approach to round off a successful 2022 exploration campaign.
“We will now use the test survey flown over the existing Libonga targets to confidently extrapolate and define anomalies of potential exploration importance along both the Libonga-Matchiti and Ngongo-Yoyo Trends.
“Further, ground-based programs will be used to de-risk any future drill programs and we are ready to start this work as we advance planned drill testing of our highest priority targets.”
Next steps
Comprehensive data analysis will continue over the coming weeks.
The company will review preliminary interpretations and targeting using its magmatic sulphide targeting toolkit to complete detailed regional target selection, including the prioritisation of target areas.
The targets will be assessed and ranked based on extensive geophysical, rock, and geochemical datasets.
Drilling will focus on testing the company’s highest priority modelled NSAMT targets for the potential occurrence of accumulated magmatic sulphides and nickel-copper mineralisation.
The drill campaign is expected to kick off during the 2023 field season after the heavy rains.
