Resource definition and extension drilling at the GEO-01 gold discovery and maiden drilling at three high-potential Pacman targets on track to commence around the end of this month

Antipa's Managing Director, Roger Mason commented 'Our expanded Phase 2 CY2023 air core drill programme was designed with the dual purpose of further interrogating the GEO-01 discovery area whilst simultaneously targeting new greenfield discoveries. We are pleased to report that the air core results released today demonstrate the GEO-01 gold mineralised footprint has increased to 700m, with a number of significant, very near surface, gold intersections returned. At the same time, results from air core drilling into anomalies near to the Minyari Deposit have successfully produced three new gold targets, which in many cases have returned mineralisation down to the end-ofhole. When combined with the results recently released from Phase 3 CY2023 RC and diamond drilling, we are very excited with the outcomes and look forward to upcoming growth and discovery drilling across our Minyari Dome and at our three high-potential Pacman targets'.

Phase 2 CY2023 Minyari Dome Project Exploration Programme The CY2023 Phase 2 exploration drilling programme at the Minyari Dome Project encompassed a total of 178 holes and 11,248m of reverse circulation (RC), diamond core and air core drilling; with receipt of the air core assays, results have now been received for all drill holes. Expanded regional Air Core programme: The expanded Phase 2 air core drill programme consisted of 150 drill holes for 5,589m which increased the systematic coverage to a 1.6km2 area surrounding GEO-01 and extended to within 300m of the Minyari Deposit. In addition, several geochemical and/or geophysical anomalies within 1.3km to 12km from Minyari were targeted with air core drill holes. Assay results have expanded the GEO-01 air core gold anomaly and produced three new gold targets.

GEO-01 discovery: The 2023 air core drilling intersected further significant near-surface high-grade gold mineralisation at GEO-01. Multiple zones of mineralisation remain open across the expanded 700m by 370m prospect footprint which is located just 1.3km from the 1.5 Moz Minyari gold-copper deposit, offering a substantial shallow potential resource opportunity.

Key GEO-01 2023 air core programme outcomes: Gold +/- copper mineralisation footprint increased from 600 to 700m.K Air core gold anomaly extended a further 100m to the southeast, including: 1m at 4.3 g/t gold from 10m down hole to end-of-hole (23MYA0205)/ 50m infill air core lines (broad 100 spaced holes on section) intersect significant gold +/- copper mineralisation in the southeast region of GEO-01 along a favourable northeast trending structural corridor, including: 5m at 1.2 g/t gold and 0.08% copper from 12m down hole to end-of-hole (23MYA0161)r 9m at 0.3 g/t gold from 12m down hole to end-of-hole (23MYA0159), including:/ 4m at 0.6 g/t gold from 16m/ Multiple zones of gold mineralisation remain open, with large areas of GEO-01 to be tested for strike and depth extensions to mineralisation during the upcoming programme.

New Rizzo target: The 2023 air core drill programme intersected gold +/- copper mineralisation and pathfinder anomalism approximately 400m from GEO-01. Key Rizzo 2023 air core programme outcomes: New target is located 370m southwest of the GEO-01 deposit.N Discovery intersection: 12m at 1.0 g/t gold and 0.12% copper from 8m down hole/ (23MYA0153). 300m zone of anomalous pathfinders including arsenic, bismuth and nickel. Mineralisation favourably located at the intersection of the north-northeast to east-northeastf trending structural corridor which hosts thick zones of gold mineralisation at GEO-01 and a favourable alkalic dolerite host rock. Broad 100 to 120m spaced air core holes, requiring infill drilling. Mineralisation present under shallow cover of just 3m. New WACA East target: The 2023 air core drill programme intersected gold mineralisation several hundred metres from the WACA and Minyari South Mineral Resource areas. Key WACA East 2023 air core programme outcomes: New target is located 230m east of WACA and 300m south of Minyari South.c Notable intersection: 10m at 0.2 g/t gold from 20m down hole to end-of-hole (23MYA0291),/ including: 1m at 0.6 g/t gold from 29m down hole to end-of-hole./ Antipa's air core drilling highlights veracity issues, of both location and assay data, of the historic (1980's) shallow open-hole percussion drill holes, meaning the WACA East trend is poorly tested along a strike length of 300 to 400m. Current round of air core drilling is broad spaced (100m), requiring infill drilling. Mineralisation present under shallow cover of just 2m. New T12 target: The 2023 air core drill programme intersected gold mineralisation across a broad area at the new T12 target. The 1.7km x 800m target returned a low level Au-Te-Bi+/-Cu soil anomaly (GEO-12) located approximately 10km northwest of the Minyari deposit, in an area with no previous drill holes. The T12 target, which was identified during Antipa's 2021 fine-fraction soil geochemical sampling programme which resulted in the GEO-01 discovery, coincides with several untested magnetic high anomalies in a fold hinge. Key T12 2023 air core programme outcomes: Located 10km northwest of the Minyari deposit.n Multiple, shallow, 4m air core intersections grading between 0.08 to 0.13 g/t gold +/- Cu-Bi/ pathfinder anomalism covering a large area >1km along strike by up to 400m across strike. Favourable address in an antiformal fold nose in interpreted Malu quartzites, with possibleM thrust faulting providing potential mineral system fluid pathways. Very broad 200 to 350m spaced air core holes, infill drilling required. Mineralisation present under shallow cover ranging between 1m and 3m.

Tetris: Located 35km northeast of the Minyari deposit, the Tetris target bears significant geophysical likeness to the Havieron gold-copper deposit (LSE: GGP). Assay results for the initial Tetris 873m diamond core hole (23TSD0001) highlighted base metal (zinc, lead), precious metal (silver +/- gold) and pathfinder (arsenic, bismuth, indium +/- molybdenum) mineral system signatures. Key Tetris geophysical modelling outcomes: Geophysical 3D inversion modelling, utilising the magnetic susceptibility data obtained from 23TSD0001, has indicated that the Tetris magnetic high anomaly may not have been satisfactorily explained. Remanence effects from the magnetic mineral pyrrhotite potentially means that the sourcer of the magnetic anomaly is offset to the northwest of 23TSD0001. This vector is compatible with the host rock bedding geometry observed in 23TSD0001. Any further Tetris drilling will be contingent on finalisation of geophysical modelling and integrated geological interpretation.

Upcoming Phase 1 CY2024 Minyari Dome Exploration Programme

Results from the completed Phase 3 drilling programme, in particular GEO-01, will inform the depth and direction of a planned 11,000m Phase 1 RC (6,000m) and diamond core (5,000m) drilling programme scheduled to commence around the end of this month. This programme will include completion of Exploration Incentive Scheme (EIS) drilling at the three Pacman greenfield targets, PM1, PM2 and PM3. The diamond core drill testing of all three large-scale greenfield targets is supported by A$660,000 of further EIS co-funding drilling grants. The CY2024 Minyari Dome Project exploration programmes and budgets are subject to ongoing review based on results, field conditions, contractor availability and pricing, and other relevant matters.
