Litchfield Minerals has intersected over 200 meters of continuous copper-zinc mineralisation at its Oonagalabi project, revealing a robust and extensive system. Planned step-out drilling aims to nearly triple the strike length to 600 meters, signalling significant exploration upside.
- Hole OGRC014 intersects 200m+ continuous copper-zinc mineralisation
- High-grade core zone of 59m with ~2% chalcopyrite and ~3% sphalerite
- Mineralised corridor extended over 300m strike and 200m vertical
- Step-out drilling planned to test 600m strike length
- Upcoming Induced Polarisation and Ground EM surveys to refine targets
A Major Step Forward at Oonagalabi
Litchfield Minerals Limited has delivered a compelling update from its Oonagalabi copper-zinc project in the Northern Territory, intersecting more than 200 meters of continuous mineralisation in drill hole OGRC014. This result not only confirms the presence of a large-scale mineral system but also highlights a thick, high-grade core zone that could underpin future resource growth.
The mineralised interval begins near surface and extends from 13 meters downhole, with a particularly notable 189-meter section averaging around 1% chalcopyrite (copper sulphide) and 1.5% sphalerite (zinc sulphide). Within this, a 59-meter zone carries elevated grades of approximately 2% chalcopyrite and 3% sphalerite, indicating a robust concentration of metals.
Expanding the Mineralised Corridor
This hole extends the known mineralised strike length by over 300 meters and confirms vertical continuity of at least 200 meters between previous drill holes. The company plans a step-out hole approximately 300 meters south of OGRC010, aiming to test whether this high-grade trend extends to nearly 600 meters. Success here would significantly enhance the project's scale and economic potential.
Managing Director Matthew Pustahya emphasised the significance of the results, noting that the footprint is shaping up as a large, fertile mineral system. He highlighted the integration of sulphide mineralisation, structural geology, and geophysical data as aligning well to guide further exploration.
Geophysical Surveys to Sharpen Focus
To complement drilling, Litchfield Minerals will commence high-definition Induced Polarisation (IP) surveys and ground electromagnetics (EM) in early November. These geophysical techniques are designed to map the subsurface conductivity and chargeability, helping to identify concealed sulphide bodies and refine drill targets, particularly around the VT2 and Bomb Diggity areas.
The Bomb Diggity cluster, where hole OGRC013 intersected finely disseminated sulphides over 40 meters, is also a focus. This area shows signs of a mineralised intrusion with a conductive sulphide halo, suggesting potential feeder zones for thicker mineralisation.
Next Steps and Market Implications
Assay results for previous holes, including OGRC010, are expected within the next few weeks, which will provide quantitative confirmation of the visual estimates reported. Meanwhile, further drilling is scheduled for early to mid-November, with four additional holes planned to test extensions and new targets.
While the current results are based on visual logging and pending laboratory assays, the scale and continuity demonstrated so far position Oonagalabi as a promising copper-zinc exploration project. The integration of drilling and geophysics is expected to accelerate discovery and resource definition in the coming months.
Bottom Line?
Litchfield Minerals is rapidly advancing Oonagalabi, with upcoming assays and geophysics set to unlock the next phase of this expanding copper-zinc system.
Questions in the middle?
- Will assay results confirm the high-grade visual estimates from OGRC014?
- Can the planned step-out drilling extend the mineralised strike to 600 meters as hoped?
- How will the new geophysical data refine targeting and impact resource potential?
