Orange Minerals Extends VMS Mineralisation 675m Down Dip at Lennon’s Find
Orange Minerals has confirmed a significant deep extension of volcanic massive sulphide mineralisation at its Lennon’s Find Project in the Pilbara, uncovering multiple new conductive targets for follow-up drilling.
- First deep diamond hole intersects broad polymetallic zone with elevated zinc, lead and silver
- Mineralisation extended approximately 675m down dip, reinforcing VMS system continuity
- Downhole EM survey reveals multiple conductive anomalies guiding next drilling phase
- Exploration co-funded by WA Government’s Exploration Incentive Scheme reduces costs
- Earn-in agreement nearing completion to secure 75% interest in key mining lease
Deep Drilling Confirms VMS Continuity at Lennon’s Find
Orange Minerals NL (ASX:OMX) has delivered a technical milestone with its maiden deep diamond drill hole (OLFD001) at the Lennon’s Find Project in Western Australia’s Pilbara. The hole, drilled to 615 metres, confirmed the continuation of volcanic massive sulphide (VMS) style mineralisation well below previously known zones, extending the system approximately 675 metres down dip. This result not only validates the geological model but also enhances understanding of the mineralised system’s architecture.
While the primary geophysical target identified by induced polarisation (IP) surveys was not directly intersected, the drill hole encountered a broad polymetallic interval from 516 to 526.6 metres featuring elevated zinc, lead and silver grades. The presence of sphalerite, galena, pyrite and chalcopyrite sulphides within this zone supports the prospectivity for thicker, higher-grade accumulations elsewhere in the system.
Electromagnetic Survey Uncovers New Targets
Complementing the drilling, a downhole electromagnetic (DHEM) survey identified multiple conductive anomalies both off-hole and in-hole. Notably, a strong off-hole conductor at 150 metres downhole correlates with sulphide mineralisation near the upper section of the hole, while other anomalies at 380–400 metres and around 480 metres downhole provide fresh vectors for targeted follow-up drilling. The latter in-hole anomaly aligns with the main mineralised interval and is interpreted as zinc-rich sulphides, which typically exhibit lower conductivity than copper-bearing equivalents.
These DHEM results are pivotal for refining exploration focus, enabling Orange Minerals to prioritise drilling towards the most prospective zones within the complex VMS system. The exploration program benefits from co-funding under the Western Australian Government’s Exploration Incentive Scheme, which helps mitigate costs and supports deeper testing efforts.
Progress on Ownership and Next Steps
Orange Minerals is advancing the finalisation of its earn-in agreement with Musketeer Mining Ltd, having satisfied the key milestones to secure a 75% interest in the Lennon’s Find mining lease (M45/368). This ownership consolidation is critical as the company prepares for systematic follow-up exploration.
Further geophysical reviews, including potential drone magnetic and Lidar surveys, are underway to sharpen drilling targets. These efforts align with Orange Minerals’ broader strategy to build on its polymetallic base metals portfolio in Western Australia while simultaneously advancing its gold projects in Ghana’s Sefwi belt, as highlighted in their recent dual gold and base metal projects update.
With a growing resource base and multiple new targets emerging from both drilling and geophysical surveys, Lennon’s Find remains a compelling exploration story to watch in the Pilbara’s competitive base metals landscape.
Bottom Line?
New deep drilling and electromagnetic targets at Lennon’s Find set the stage for focused exploration that could unlock thicker, higher-grade VMS mineralisation.
Questions in the middle?
- Will follow-up drilling confirm the economic significance of the newly identified polymetallic intervals?
- How will the ongoing earn-in agreement influence Orange Minerals’ strategic control and investment in Lennon’s Find?
- Can further geophysical surveys refine the understanding of the unresolved IP anomaly that OLFD001 did not intersect?
