Antipa Minerals Limited announce assay results for the CY2022 Phase 2 greenfield drilling programme at its 100%-owned, 877km 2 Minyari Dome Project in Western Australia's Paterson Province. The Minyari Dome Project is located within 35km of Newcrest Mining's (Newcrest) Telfer gold-copper-silver mine and mineral processing facility and 54km along strike from Newcrest-Greatland Gold's Havieron gold-copper development project. CY2022 Phase 2 Exploration Programme The second phase of the Minyari Dome CY2022 Exploration Programme involved approximately 9,000m of drilling which was completed in mid-December and comprised: resource definition diamond drilling (DD) programme for Minyari deposit (4,365m); resource growth DD programme testing high potential resource targets (2,813m); and first-pass air core (AC) drill programme testing high-priority greenfield soil targets (1,400m).

Assay results from the Phase 2 resource definition DD programme have previously been released. This release contains all assay results from the Phase 2 growth DD and air core programmes. Combined results from CY2022 Phase 1 and Phase 2 resource growth and exploration drilling support the opportunity for further significant resource growth from several prospects located less than 400m from the Minyari and WACA deposits.

High priority opportunities identified include the Minyari North, GEO-01, Chicane and GP01 targets. Minyari Dome Project Soil Geochemical Target Air Core Results: At the GEO-01 soil target multiple shallow (17 to 65m), vertical, very broad spaced (100m drill grid) AC holes intersected thick zones of encouraging alteration, veining and variable gold-copper mineralisation under very shallow cover. The GEO-01 first-pass AC drill programme defined a mineral system covering an area the size of the Minyari deposit (approximately 700m by 400m).

The GEO-01 footprint is open in several directions, including a number of holes which end in mineralisation (at drill bit refusal), which provides a potentially substantial maiden Mineral Resource opportunity. Planning is underway for a future drilling programme to follow-up these highly encouraging AC results targeting delivery of a near surface, open pit amenable, maiden resource. GEO-01 Soil Anomaly Target Summary: 800m x 800m Au-Cu-Te±Bi±W soil anomaly located 1.2km and 400m southeast of the Minyari and WACA deposits respectively; Soil anomaly coincides with a magnetic anomaly in a fold hinge; Very shallow cover between 4 to 16m; Southern limit of GEO-01 mineralisation abuts the tenement boundary with Antipa's Paterson IGO Farm-in Project (currently 100% Antipa); Phase 2 first-pass air core programme included 27 vertical holes for 996m (with 100m x 100m drill grid), with intersections including: 30.0m at 0.38 g/t gold from 6.0m down hole in 22MYA0105, including: 20.0m at 0.51 g/t gold from 10.0m, also including: 4.0m at 1.46 g/t gold from 10.0m.

2.0m at 0.85 g/t gold from 16.0m to end-of-hole (EoH) in 22MYA0109, including: o1.0m at 1.28 g/t gold from 17.0m to EoH. 14.0m at 0.29 g/t gold and 0.03% copper from 24.0m down hole in 22MYA0120, including: o 4.0m at 0.69 g/t gold and 0.04% copper from 32.0m 32.0m at 0.22 g/t gold and 0.06% copper from 16.0m down hole in 22MYA0138, including: 4.0m at 0.69 g/t gold and 0.04% copper from 32.0m. 18.0m at 0.31 g/t gold from 16.0m to EoH in 22MYA0141, including: 4.0m at 0.51 g/t gold from 28.0m to EoH.

No historical RC or DD holes in the area, previous deepest exploration being a 65m vertical AC hole (2022) Follow-up RC ± DD drill programme a high priority GEO-02 Soil Anomaly Target Summary Phase 2 first-pass air core programme included 13 vertical holes for 404m (with 100m by 180m drill grid) Minor anomalism (including 2m at 0.13 g/t gold in 22MYA0129 from 24m downhole) No further work planned Minyari North: Thick zones of Minyari style alteration, brecciation, veining and gold-copper mineralisation have been defined along 300m of strike by five broad spaced (> 100m) drill holes, including two Phase 2 DD holes for 1,717m. Mineralisation is interpreted to be moderate northwest plunging similar to the Minyari deposit and remains open in several directions providing a significant potential maiden resource opportunity which is a priority for follow-up drill testing. Minyari North Summary: Located 400m northwest along strike from the Minyari deposit; Coincident magnetic-high and IP chargeability anomaly with similarities to the Minyari deposit; Minyari North interpreted to be the fault displaced continuation of the upper portion of the Minyari orebody; Significant intersections from the five very broad spaced drill holes include: 28.0m at 1.0 g/t gold from 239.0m down hole in 22MYD0522, including: o 8.0m at 2.6 g/t gold from 239.0m, also including: 1.0m at 15.8 g/t gold from 239.0m.

Previously reported 28.0m at 0.5 g/t gold and 0.16% copper from 134.0 down hole in 21MYC0336, including: o 1.0m at 8.1 g/t gold and 0.24% copper. Open up plunge to the south toward Minyari, down plunge to the north towards the Judes copper-silver-gold deposit, and up and down dip. Minyari Deeps Down Plunge: The initial test of the Minyari Deeps Plunge target involved one deep DD hole 22MYD0520 for 1,096m.

The hole intersected multiple zones of variable alteration with only minor gold-copper mineralisation (maximum assay results 1.46 g/t gold, 2.35% copper and 8.7 g/t silver) below the ‘mine' host sequence. A major fault zone was intersected from 333 to 343m downhole which is interpreted to have displaced the ‘mine' sequence vertically up between 300 to 400m and as a consequence 22MYD0520 has drilled below the fault displaced target zone. Structural and lithological interpretations based on drill hole and geophysical data imply that Minyari North is the northward extension of the upper portion of the displaced Minyari orebody.

The up plunge southerly extension of the Minyari North gold-copper mineralisation may be present above drill hole 22MYD0520. This shallower plunge target is amenable to RC drill testing which is to be included as part of the future Minyari North resource delineation drilling programme. current year 2023 Resource Growth Exploration Programme: Antipa is targeting a significant increase to the Minyari Dome Project Mineral Resource estimate through CY2023 via testing of a range of gold-copper-cobalt resource extension targets, resource prospects, and greenfield exploration target opportunities.

This extensive further resource growth drilling at Minyari Dome is set to run in parallel with the Minyari Dome Pre-Feasibility Study workstreams (targeting completion by end Fourth Quarter current year 2023).
