Deep Drilling at Lennon’s Find Could Reshape Project’s Resource Outlook
Orange Minerals NL has commenced a 650m diamond drilling program at its Lennon’s Find polymetallic project in Western Australia, targeting a deep geophysical anomaly that could reveal new mineralisation beneath an existing resource.
- 650m diamond drill hole underway targeting deep copper/gold anomaly
- Lennon’s Find hosts a 4.5km mineralised corridor with high-grade surface assays
- Existing JORC 2012 Inferred Resource includes zinc, lead, silver, gold
- Drilling supported by WA Government Exploration Incentive Scheme grant
- First deep drill test aims to explore volcanic massive sulphide system potential
Exploration Steps Up at Lennon’s Find
Orange Minerals NL has initiated a significant new phase of exploration at its Lennon’s Find Project in Western Australia’s Pilbara region, commencing a 650-metre diamond drilling program to test a deep induced polarisation (IP) anomaly. This marks the first time the project has been probed at depth, aiming to unlock potential mineralisation beneath the well-documented near-surface resource.
The Lennon’s Find Project is defined by a striking 4.5-kilometre mineralised corridor, where recent rock-chip sampling has returned impressive grades, including silver assays up to 2,948 grams per tonne, gold at 3.55 grams per tonne, and lead reaching 17.4%. These surface results have bolstered the interpretation of a volcanic massive sulphide (VMS) system at depth, a style of deposit known for polymetallic richness.
Geophysical Clues Point to Deeper Potential
The target for the current drilling is a deep copper and gold anomaly identified through a detailed IP survey conducted in September 2024. This geophysical signature aligns with a magnetic linear trend and an overlying fault structure, suggesting a possible feeder zone to the known zinc-lead-silver mineralisation. Previous drilling at Lennon’s Find has been relatively shallow, focusing on oxide zones, leaving the deeper sulphide system largely untested.
Orange Minerals’ Managing Director, Chris Michael, expressed optimism about the drilling program, highlighting the robust technical foundation underpinning the target selection. "The anomaly we’re testing lines up with both the magnetic trend and a key structural feature in the area," he said. "It’s a well-supported target and this hole will give us our first proper look at what’s happening at depth."
Backing from Government and Industry
The drilling is being executed by Terra Drilling and benefits from a $110,930 grant from the Western Australian Government’s Exploration Incentive Scheme, underscoring the project’s regional significance and potential. The existing JORC 2012 Inferred Resource at Lennon’s Find stands at 1.55 million tonnes grading 5.9% zinc, 1.6% lead, 0.28 grams per tonne gold, and 84 grams per tonne silver, all hosted on a granted mining lease.
Orange Minerals is positioning Lennon’s Find as a key asset within its portfolio, which also includes projects in New South Wales and Ghana. The company’s systematic, data-driven approach to exploration aims to build on these promising early results and advance the project towards resource growth and eventual development.
Looking Ahead
While the drilling results are still pending, this deep test could redefine the scale and scope of mineralisation at Lennon’s Find. Success here would not only enhance the project’s value but also reinforce the Pilbara’s credentials as a polymetallic province beyond its famed iron ore and gold deposits.
Bottom Line?
The coming assay results will be pivotal in determining whether Lennon’s Find can evolve from a near-surface resource into a deeper polymetallic discovery.
Questions in the middle?
- Will the deep drilling confirm the presence of a volcanic massive sulphide system at depth?
- How might new assay results impact the current JORC resource estimates?
- What are the next exploration steps if the deep anomaly proves mineralised?
