Resolution Minerals’ (ASX: RML) geophysics surveying work at its Wollogorang project in the Northern Territory has highlighted the potential presence of copper by identifying 40 conductors.
This, the company says, has produced many new targets, all so far untested. It is now drawing up a priority list of drill targets.
VTEM (versatile time domain electromagnetic) surveys are able to detect sub-surface conductive bodies, such as sulphides and other trap sites for base metals, to a depth of 400m.
The company says it is now in the process of using the VTEM results to plan and prioritise drilling targets.
Drilling is planned for late August at the VTEM targets and the Gregjo prospect, subject to rig availability.
Wollogorang is 100% owned by Resolution and covers 3,825sq km and, is believed to be “highly” prospective for the sedimentary hosted battery metals copper and cobalt.
Exploration has taken ‘fresh approach’
Previous exploration by Resolution intersected high-grade shallow copper mineralisation during drilling at the Gregjo prospect where one hole returned 7m at 1.23% copper, including a 1m interval at 4.24%.
The Gregjo prospect is fully permitted, drill-ready, open along strike and accessible in the dry season (which is from May to late November in a normal year).
Resolution managing director Duncan Chessell said the company’s geology team had taken a “fresh approach” to the project using a wide-spaced, powerful VTEM Max geophysical survey.
Project now ‘wide open’ to copper discoveries
“It’s paid off with these better-than-expected VTEM geophysics results,” he said.
“The conductors identified could indicate the presence of massive sulphides or the presence of rocks that could be excellent trap sites for base mineralisation.”
“The project is now wide open for copper discoveries.”
“What has most excited now is that that VTEM has generated dozens of untested new targets,” Mr Chessell added.
Previous exploration had focused on discrete breccia pipes which demonstrated the presence of copper and cobalt in the system.
However, these pipes were deemed by Resolution to be not sufficient in scale to warrant further work.
