Litchfield geophysics chases huge sulphides at NT poly-metals play
Recently ASX-listed critical minerals explorer Litchfield Minerals is on track to this week finish a combined electromagnetic and magnetic geophysical survey of its entire Oonagalabi poly-metallic project in the Northern Territory's Harts Range. With a $500,000 capital raise under its belt and its disciplined 'fail fast or succeed quickly' approach, Litchfield aims to unlock a 3-kilometre-long polymetallic system rich in copper, zinc and, potentially, gold, silver, bismuth and cobalt. Litchfield launched a 1015-line-km helicopter-borne VTEM Max electromagnetic and magnetic survey two days ago over its Oonagalabi licence area under a contract with UTS Geophysics. It is using a 200m line spacing over 819-line-kilometres, which is being narrowed to a 100m infill spacing over 196-line-kilometres of high-priority zones. The survey is targeting conductive massive sulphide mineralisation at depth and is already 21 per cent complete. It is designed to detect copper-zinc-rich sedimentary exhalative (SEDEX) or skarn-style systems, which often host chalcopyrite and pyrrhotite. 'The VTEM survey is a major step forward for Oonagalabi. We already know from drilling that we have copper-zinc sulphides in the system and VTEM gives us the ability to see the bigger picture - both laterally and at depth.' Litchfield Minerals managing director Matthew Pustahya SEDEX deposits are a type of metal ore deposit primarily known for their rich concentrations of lead, zinc and silver. They form when metal-rich, hydrothermal fluids are discharged onto the sea floor, precipitating sulphide minerals, which often layer within sedimentary rocks. Litchfield expects to receive the survey results in September. These will guide a program to drill high-priority conductors, the project's intriguing priority Bomb Diggity magnetic anomaly/interpreted intrusive body and other potential gold-bearing intrusions. Litchfield Minerals managing director Matthew Pustahya said: ' The VTEM survey is a major step forward for Oonagalabi. We already know from drilling that we have copper-zinc sulphides in the system and VTEM gives us the ability to see the bigger picture - both laterally and at depth. The potential for Oonagalabi to be either a SEDEX or skarn system is exciting, as both are known to host high-grade massive sulphide zones, which VTEM is ideally suited to detect.' Pustahya said the survey would also deliver full airborne magnetic coverage, sharpening the company's geological models and enabling it to target the project's most prospective zones with greater confidence.
