Armada Metals Ltd (ASX:AMM) has identified multiple discrete, very strong apparent conductors from modelling of ground natural source audio-magnetotelluric (NSAMT) survey data which will be used to drive future drill programs at the Nyanga Project in Gabon.
Notably, two new concealed targets, Libonga Central and Libonga Central Extension, have been delineated between the existing Libonga North and Libonga South targets.
The untested apparent conductors are consistent with the anticipated intrusion morphologies and are likely associated with localised significant accumulations of magmatic sulphides.
Moving forward, a 1,500-line-kilometre MobileMT survey, the latest innovation in airborne electromagnetics, is planned at the Nyanga Project - the first deployment of this airborne technology on the African continent.
“Potential game-changing opportunity”
Armada managing director and CEO Dr Ross McGowan said: “The current modelling and technical review represent another successful step in our exploration approach, with the NSAMT survey delivering better than expected results that will directly impact our next drill program.
“The NSAMT survey has achieved its objective of directly detecting discrete conductive bodies, with recognisable geometries, that will be used to generate priority drill targets.
“Importantly, the latest data provides us the ability to confidently define anomalies of potential exploration importance within the Nyanga Project area.
“The fact that the modelled conductors start near the surface and continue to depth offers real encouragement for the potential of the Nyanga Project to host magmatic sulphides.
“With the mobilisation of the innovative MobileMT system from Expert Geophysics Ltd in progress, we are excited at the prospect of defining additional exploration targets to test in a future drilling program.
“This is the first time this MobileMT system has been deployed on the African continent and is a potential game-changing opportunity for the company”
Forward plan
The MobileMT survey is expected to kick off in the first half of December and take around 2-3 weeks to complete.
Subsequently, a more comprehensive series of ground NSAMT surveys will be completed on individual prioritised regional targets, resulting from the Mobile MT survey, ahead of drilling testing.
Drilling will be focused on testing the company’s highest priority modelled NSAMT conductors for the occurrence of accumulated magmatic sulphides and nickel-copper mineralisation.
