By improving geological confidence in areas between known or surface-mappable outcrops, Litchfield hopes to define fresh targets that can be quickly tested by drilling.
Once that work is complete, the focus will shift to a prominent arc-shaped structure identified in magnetics that trends towards its VT1 target, which is a standout electromagnetic (EM) anomaly with a high conductivity of about 3000 Siemens.
Litchfield Minerals managing director Matthew Pustahya said: โOur next major step at Oonagalabi is to track this system beyond what we can easily see at surface. We know the Oonagalabi Formation is prospective, and weโve already seen the scale it can run to across the project. This IP survey is designed to chase the formation south toward Silverado, then pivot to follow a major magnetic structure toward VT1, where a very strong EM conductor was defined and over a kilometre of Oonagalabi-style geology was mapped during the EM program.โ
That 3000 Siemens number alone is enough to make geophysicists sit up, but the story gets better. During earlier EM work, more than a kilometre of Oonagalabi-style geology was traced along the corridor, pointing to the same rich stratigraphy riding the coincident magnetic trend and lighting up the strong VT1 conductor.
For Litchfield, this coincidence of signatures is important. Magnetics and conductivity, tied in with structure and known prospective rock horizons and all lined up along a single trend, is exactly the sort of recipe explorers look for when building a portfolio of drill-ready targets.
In a nutshell, the IP survey is set to sharpen the picture, peeling back the cover to spotlight sulphide-rich zones and structural traps that could mark the next wave of discovery.
In a market that continues to reward credible copper stories, Litchfieldโs methodical approach stands out. Rather than rushing blindly into drilling, the company appears to be stacking the odds in its favour by using modern geophysics to more accurately guide its next moves.
