Arrow Minerals Ltd (ASX:AMD) has identified seven large discrete conductors in an airborne electromagnetic survey at the Strickland Copper-Gold Project in Western Australia.
The conductors are coincident with strong copper and gold anomalism of up to 2.2% copper and 9.6 g/t gold in historical drilling.
All seven conductive anomalies are shallow and correspond with geochemical and geological environments favourable for volcanogenic massive sulphide (VMS) mineralisation.
Prioritising new targets
Arrow’s managing director Howard Golden said: “These conductors, with the coincident copper-gold-silver-zinc-bismuth anomalism and their geological settings, are typical of the VMS environment as seen at the Golden Grove and Perrinvale VMS deposits.
“We are now prioritising these exciting new targets for follow-up drill testing.”
Electromagnetic survey
Arrow completed a 680 kilometres linear survey using the SkyTEM helicopter-borne transient electromagnetic (TEM) system in late September 2020.
The survey comprised of five blocks distributed throughout the Strickland licences in Western Australia covering an area of 131 square kilometres.
The survey was designed to test strong geochemical signatures consistent with volcanogenic massive sulphide (VMS) copper-gold mineralisation identified in the analysis of historical data.
Geochemical anomalism
Base metals geochemical anomalism was detected in geochemical samples from previous aircore and reverse circulation drilling that focused exclusively on orogenic gold exploration.
Recent studies of this historical data highlighted the potential for VMS copper and gold mineralisation at five high-quality target areas in the Strickland tenement block.
Next steps
The conductors detected in the TEM survey at Strickland provide drill targets with geological and geochemical support for VMS copper-gold mineralisation.
Arrow will undertake a program to ground-truth the anomalies in the field followed by drill testing on all anomalies that are shown to be prospective.
In parallel with Strickland, Arrow continues to explore for gold in Burkina Faso, focusing on the recent Dassa discovery in the west of the country.
These projects in Western Australia and Burkina Faso allow Arrow year-round access to projects during their respective field seasons.
