Oonagalabi is interpreted to have formed within a syngenetic, SEDEX-type or an epigenetic carbonate-replacement / skarn-type environment and these deposits are known globally to host high-grade conductive mineralization. Stratigraphic conductors or overburden are not present within the project and VTEM was considered the most appropriate technique to define sub-surface, sulphiderich mineralization. Other than some trial VLF lines in the 1970's, no electromagnetic technique had been completed at the Oonagalabi Project. The prospect currently has a reasonably well-defined, low-grade, disseminated sulphide zone that is estimated to host a non JORC-compliant resource of approximately 25Mt @ 0.5% Cu, 1% Zn, 0.1 g/t Au, 4 g/t Ag. In February 2025, Litchfield Minerals completed a Pole-Dipole IP survey (PDIP) that defined a +1km long, +20mV/V chargeability anomaly (to +60mV/V) that is up to 300m wide with a vertical extent exceeding 200m from surface. Historic and 2025 RC drilling clearly demonstrated that the IP chargeability anomalies are related to disseminated sulphides. This sulphide zone is hosted within the Oonagalabi Formation (dominantly anthophyllite, calc-silicate, marble and garnet quartzite) and is interpreted to host higher-grade feeder zones or remobilized sulphide mineralized zones. The PDIP survey defined extensive zones of chargeability with no geological surface expression, highlighting the importance of geophysics to improve sub-surface 'visibility'. The VTEM survey produced a high quality dataset that defined six high-priority, late-time sulphide-bearing basement conductors including four conductors within the older Aileron Province basement and two conductors within the over-thrusted and younger Irindina Province. Conductors were modelled by Kate Hine (Mitre Geophysics) and subsequent RC drilling of the VT2 conductor in late 2025 (OGRC011, OGRC019) intersected narrow zones of stringer, semi-massive and massive sulphides (pyrrhotite-chalcopyrite-sphalerite) hosted within metamorphosed mafic intrusive rocks (amphibolite). RC drilling of the VT1 conductor (OGRC012) intersected a 60m zone of weekly disseminated sulphides (pyrite-chalcopyrite-pyrrhotite) within felsic gneiss, amphibolite and an 8m wide massive quartz vein. Subsequent downhole EM and ground EM at VT1 defined two small conductors (50m strike, 1,500S and 3,000S), approximately 50m to the south and updip from OGRC012. Outside of VT1 and VT2, additional conductors within the Aileron basement are all spatially-associated with depth persistent magnetic anomalies, most likely relating to amphibolite intrusions. The two priority conductors within the overlying Irindina rocks are less well-developed than in the Aileron basement and are most likely related to Virginia-type, structurally-controlled epigenetic copper mineralisation. 2026-01-01T00:00:00Z https://geoscience.nt.gov.au/gemis/ntgsjspui/handle/1/94498 Title: GR563 Carrara Project EL32476 Partial Surrender Report, EL32476 20 October 2021 to 20 September 2025 Author: Crombez, V Abstract: The Carrara Project is located in the Barkly Tablelands approximately 340km east northeast of Tennant Creek, 730km southeast of Katherine and 630km northeast of Alice Springs and consists of three exploration licences covering a total area of approximately 1,202 square kilometres. These were granted to Baudin Resources Pty Ltd (a fully owned subsidiary of Encounter Resources Ltd - 'Encounter'). Carrara is considered prospective for sediment-hosted Zn - Pb and Cu mineralization. In June 2022, South32 and Encounter entered into a Farm-in Agreement covering the Carrara Copper - Zinc Project. In September 2024 Encounter regained 100% ownership and operatorship over the entire Carrara Project tenure. Following a review of Encounter Resources' exploration portfolio, the decision was made to surrender a significant part of EL 32476. Although this licence had previously represented a prospective exploration area, updated assessments showed that the primary targets now lie below technically and economically viable exploration depths, reducing their potential value and resulting in a lower ranking within the broader portfolio. 2025-01-01T00:00:00Z https://geoscience.nt.gov.au/gemis/ntgsjspui/handle/1/94497 Title: Benmara Project Group Report (GR599) EL 31287, EL 32229, EL 32849, EL 32850, EL 33612 and EL 33613 for the period 1st February 2025 to 3rd April 2025; and EL 32228 and EL 32883 for the period 1st February 2025 to 30th September 2025 Group Annual and Final Technical Report Author: Price, G Abstract: This report is the final group technical summary of work carried out by Resolution Minerals Ltd (RML, Resolution) on the Benmara Project. A corporate restructure of Resolution Minerals Ltd occurred during the 2024-25 reporting period which led to a detailed review of the prospectivity of the GR599 group of tenements being conducted. Following completion of this review, a decision was reached to formally halt exploration on GR599. A formal application to surrender all tenements (excluding EL 32228 and EL 32883) was lodged on 3rd April 2025. No field exploration was conducted at GR599 in the final reporting period apart from a rehabilitation program which was finalised in May 2025 at sites where the 2023 diamond drilling was conducted. Area reductions of EL 32228 (effective 29th March 2025) and EL 32883 (effective 17th June 2025) to 4 blocks each were lodged with the DME in June. Applications for the full surrender of EL 32228 and EL 32883 were lodged 13th August 2025 and accepted 30th September 2025. 2025-01-01T00:00:00Z https://geoscience.nt.gov.au/gemis/ntgsjspui/handle/1/94496 Title: Benmara Project Group Report (GR599) EL 31287, EL 32228, EL 32229, EL 32849, EL 32850 and EL 32883 for the period 1st February 2024 to 31st January 2025; and EL 33612 and EL 33613 for the period 10th April 2024 to 31st January 2025 Group Annual Technical Report Author: Price, G Abstract: This report is the second group technical summary of work carried out by Resolution Minerals Ltd (RML, Resolution) on the Benmara Project.
