Havilah Resources Limited reported good progress on the Study Program, exploration drilling under the Curnamona Province Strategic Alliance (Strategic Alliance) and TAD (Think and Act Differently) incubator initiatives, all funded by OZ Minerals Limited. As a result of unavoidable delays caused by unseasonably heavy rains and receipt of requisite land access approvals, Havilah and OZ Minerals have agreed to a 69 day extension to the Study Program under the force majeure provisions. This will have the effect of extending the period for exercise of the Kalkaroo Option by 69 days to 10 May 2024 (if not exercised earlier or further extended).

The exploration drilling program is initially focusing on 7 separate high priority copper prospect areas within Havilah's 100% owned exploration licence (EL) 6659 within 15km of the Kalkaroo copper-gold-cobalt project (Kalkaroo). The objective is to locate additional copper resources close to Kalkaroo that could be additive to the existing Kalkaroo JORC Mineral Resource and so enhance its development prospects. At the time of writing 37 reverse circulation (RC) percussion drillholes had been completed for a total of approximately 6,772 metres on 4 of these copper prospects, namely Johnson Dam, Deep Well, Main Dome NW and Kalkaroo West prospects.

2,332 drill samples have been submitted to an Adelaide assay laboratory. Detailed reporting and geological interpretations will be provided upon receipt of complete laboratory assay results and subsequent evaluation by geologists, including the relevant Competent Person. The Johnson Dam copper anomalous sulphide gossan (ironstone) was drilled first and intersected an approximately 30 metre thick quartz-carbonate-sulphide zone in several drillholes.

It was initially recognised during 1988 by CSR Exploration who reported rock chip samples of gossanous ironstone assaying over 1,000 ppm copper. The gossan outcrops over 1 km of strike and is coincident in part with a linear magnetic feature, which may represent a possible shear zone. Drilling is presently concentrated on the Kalkaroo West prospect area on the possible western strike extensions of the Kalkaroo fault zone that is an interpreted major control on the Kalkaroo mineralisation.

One diamond drilling rig is currently operating on 2 shifts within mining lease (ML) 6498 during the phase 1 drilling program. Initially 30 diamond drillholes are planned including 7 geotechnical holes and 23 holes that twin existing Havilah RC drillholes. This drilling program has several key objectives: Resource verification and checking for any bias in Havilah's earlier drilling results.

Obtaining representative metallurgical bulk samples. Gathering detailed structural information for geotechnical inputs to inform open pit designs. Evaluating data quality of historical Havilah drilling programs. OZ Minerals has set up its own drillcore logging, cutting and density measurement facilities on site to handle the expected volume of drillcore and has assigned 3 experienced geologists to this task.

Orexplore Technologies Limited (Orexplore) has established a core scanning facility on site using its GeoCore X10 hardware and its Insight software. The site is presently scanning historical drillcore and producing digital core models that are able to be remotely interpreted by the geology and study teams. The scanning is able to generate a high resolution 3D digital data set containing structural, mineralogical, textural, density, and other information that can deliver improved orebody knowledge and help to design optimised processing facilities. This process effectively results in a cloud-based virtual core farm that can be viewed digitally at any time.

A primary objective of this work is to evaluate the variability of physical properties, mineralogy and other orebody attributes across the Kalkaroo orebody to complement resource modelling and metallurgical studies. A temporary 33 person fully catered camp to accommodate OZ Minerals and other contract personnel working on site is now operational. This will relieve the pressure on Havilah's exploration camp that has provided the bulk of accommodation of site personnel over the last several months and will offer more comfortable accommodation for a greater number of personnel working on site.

According to the stated TAD objectives, this work is designed to create value by having the ability to assess and carry many more options, with greater speed and with the inclusion of a much more diverse set of perspectives than might be traditionally done when assessing a project like Kalkaroo. Orexplore drillcore scanning at Kalkaroo is a TAD incubator initiative. The core scanning data will be integrated with a new Kalkaroo base geological model and resource block model being compiled by TAD ecosystem companies using Havilah's historic database.

The immediate objective is to generate optimised mining and processing plans that will form the basis for a fast-tracked economic model that is planned to be delivered by mid-year.
