Key Highlights

Coherent 1km magnetic target identified immediately along strike from the Cousin Jack discovery, derived from high-resolution drone magnetic survey data processed during the quarter
Magnetic target coincides with an IP chargeability anomaly, providing a second geophysical dataset supporting a possible association with disseminated sulphides
Lewis Ponds hosts a JORC 2012 Mineral Resource of 17.52Mt at 1.12g/t Au, 53.34g/t Ag, 2.06% Zn, 1.10% Pb and 0.14% Cu (9.09Mt Indicated and 8.43Mt Inferred)
Previous Cousin Jack drilling intersected broad polymetallic zones including 79m at 1.3% ZnEq from 311m, 86m at 0.6% ZnEq from 408m and 104m at 1.3% ZnEq from 527m

Orbit Resources Limited (ASX:OBT) has announced the identification of a coherent magnetic anomaly extending over a strike length of one kilometre immediately adjacent to its Cousin Jack discovery at the Lewis Ponds gold, silver and base metals project in New South Wales. The target was defined from high-resolution drone magnetic data collected during August and September 2026 and subsequently processed by the company's geophysical consultants.

The Lewis Ponds Project covers approximately 148 square kilometres in the Lachlan Fold Belt, located 15 kilometres east of Orange, NSW. The project hosts an existing JORC 2012 Mineral Resource of 17.52 million tonnes at 1.12 grams per tonne gold, 53.34 grams per tonne silver, 2.06% zinc, 1.10% lead and 0.14% copper, split between 9.09 million tonnes in the Indicated category and 8.43 million tonnes in the Inferred category.

Geological Basis for the Magnetic Target

The exploration significance of the new magnetic anomaly rests on the observed geological relationship at the Cousin Jack discovery itself. At Cousin Jack, magnetic pyrrhotite — a magnetically susceptible iron sulphide mineral — occurs in direct association with polymetallic mineralisation containing sphalerite (zinc sulphide), galena (lead sulphide) and chalcopyrite (copper sulphide), together with silver and gold. This known association provides a direct geological basis for inferring that the newly defined magnetic anomaly may reflect a similar sulphide assemblage extending along strike from the discovery.

The magnetic anomaly also coincides with an Induced Polarisation chargeability response from a survey completed in December 2025. IP chargeability anomalies are commonly associated with disseminated sulphide mineralisation, and the coincidence of both a magnetic response and an IP response at the same location provides a stronger exploration case than either dataset alone. Together, the two geophysical datasets — considered alongside the known mineralogy at Cousin Jack — make the one-kilometre magnetic trend a priority target for assessing potential along-strike extensions to the discovery.

Cousin Jack Polymetallic Mineralisation in Context

Previous drilling at Cousin Jack has intersected broad zones of polymetallic mineralisation in drillhole GLPRCDD003, including 79 metres at 1.3% zinc equivalent from 311 metres, 86 metres at 0.6% zinc equivalent from 408 metres and 104 metres at 1.3% zinc equivalent from 527 metres. These intercepts establish the presence of a substantial polymetallic system and provide geological context for assessing whether the adjacent magnetic trend represents an extension of this mineralised corridor.

The discovery sits within the Lachlan Fold Belt, a geological province in New South Wales with a well-documented history of producing significant gold, silver, zinc, lead and copper deposits. The geological setting is considered prospective for the style of mineralisation observed at Cousin Jack.

Immediate Fieldwork and Ground EM Program

Following the identification of the magnetic target, the company announced that field investigation would commence immediately. Ground Electromagnetic surveying is scheduled as the next stage of follow-up work. Ground EM is effective for detecting conductive sulphide bodies at depth and will provide higher spatial resolution than the airborne and IP data collected to date, helping to more precisely locate and characterise any conductive sulphide source responsible for the magnetic and IP responses.

The ongoing diamond drilling program at Lewis Ponds — designed to strengthen confidence in the existing Mineral Resource and test exploration targets away from the MRE area — was described as nearing completion at the time of the announcement, with assays pending.

Risks

The magnetic and IP anomalies identified at the new target are geophysical responses that may or may not reflect economic mineralisation at depth — the geological interpretation, while well-reasoned, remains unconfirmed by drilling. The results of the diamond drilling program currently underway at Lewis Ponds will be important for assessing the broader reliability of geophysical targeting approaches at the project. Small-cap explorers in New South Wales face regulatory and community engagement considerations for any new drilling campaign. The polymetallic nature of Lewis Ponds means the project's Economics are sensitive to multiple Commodity prices including zinc, lead, gold and silver, all of which are subject to independent market forces.

What to Watch Next

The most important near-term developments will be the results of the ground EM survey at the new magnetic target and the assay results from the current diamond drilling program at Lewis Ponds. The ground EM survey will help confirm whether a drill-ready conductive sulphide target exists beneath the magnetic anomaly. Assay results from the diamond drilling program will also be significant — both for the existing MRE and for any results from the exploration targets away from the MRE area. A positive response from both programs could support a further round of drilling targeting the new one-kilometre magnetic trend.

Sector Context

The Lachlan Fold Belt in New South Wales hosts a number of significant past-producing and currently operating polymetallic mines, and the belt's geological prospectivity is well established. The identification of along-strike extensions to known mineralised systems is a common exploration strategy in this setting, and the use of integrated geophysics — combining drone magnetics with historical IP data — reflects modern best practice for targeting sulphide-associated mineralisation. For investors, the coincident geophysical anomalies immediately adjacent to a known polymetallic discovery represent a well-defined exploration target with clear follow-up logic.
