ASX Quarterly Report and Appendix 5B for the Period ended 31 March 2022

Highlights

  • Major drilling programmes on all four of Antipa's Projects in WA's Paterson Province were completed in late CY 2021, with a significant number of assay results pending at 31 March:

    • 100% owned Minyari Dome Project: expanded ~53,000m (Diamond Core (DD) + Reverse Circulation (RC) drilling) - assays outstanding for final 6,440m (RC drilling) for greenfields targets;

    • Citadel Joint Venture with Rio Tinto1: ~24,500m (DD + RC drilling) - assays outstanding for final 6,833m;

    • Wilki Farm-in with Newcrest2: ~8,000m (RC + DD drilling) - assays outstanding for final 606m; and

    • Paterson Farm-in with IGO3: ~11,500m (Air Core) - all assays outstanding.

  • 100% owned Minyari Dome Project results continue to extend the potential size of the Mineral Resource Estimate (MRE) (current 2017 combined JORC 2012 MRE of 723koz gold at 2.0 g/t and 26kt copper at 0.24% for Minyari and WACA4) and enhance a project development opportunity, including as a potential standalone development. The Minyari MRE was last updated in 2017, with the 2022 MRE update imminent.

  • Minyari Dome Project CY 2021 exploration programme continued with additional DD and RC results received during the Quarter, key highlights of which include:

Operations Review - Minyari Dome Project (including Minyari and WACA Deposits) - 100% Antipa

The Company holds a 100% interest in the 144km2 Minyari Dome Project located approximately 30km north of Newcrest's giant Telfer gold-coppersilver mine and processing facility. The Minyari Dome Project includes the Minyari and WACA goldcopper-silver-cobalt deposits and Mineral Resources and provides the Company with immediate exploration and future development opportunities.

Key metrics of the Minyari Deposit include:

  • High-grade gold with copper, silver and cobalt;

  • Mineralisation commences 0 to 10 metres from the surface and extends down for more than 670 vertical metres;

  • +500m strike length;

  • Multiple zones of mineralisation occur within a mineralised corridor up to 300m in width; and

  • Remains open down dip and down plunge along strike.

Key metrics of the WACA Deposit include:

  • Located only 580m southwest of the Minyari deposit;

  • High-grade gold with copper (and minor silver and cobalt);

  • Mineralisation commences 0 to 20 metres from surface and extends for more than 510 vertical metres;

  • +650m strike length;

  • Multiple zones of mineralisation occur within a mineralised corridor up to 100m in width; and

  • Remain open down dip and down plunge along strike, including very high-grade gold shoots.

The current 2017 Mineral Resource estimates for both the Minyari and WACA deposits are summarised in Table 1 and Tables 2a-b below (Mineral Resource).

In 2017 the Company engaged consultants Optiro Pty Ltd to complete an independent Mineral Resource Estimate and subsequent reporting, in accordance with the 2012 JORC Code, for the Minyari and WACA deposits. Both deposits are potentially amenable to open pit and underground mining methods. The Minyari results continue to extend the potential size of the MRE (current 2017 combined JORC 2012 MRE of 723koz gold at 2.0 g/t and 26kt copper at 0.24% for Minyari and WACA) and enhance a project development opportunity,including as a potential standalone development. The Minyari MRE was last updated in November 2017, with the 2022 MRE update imminent.

The Minyari Dome Project, including the Minyari and WACA deposits, are not subject to the Citadel Project Joint Venture with Rio Tinto, the Wilki Project Farm-in with Newcrest or the Paterson Project Farm-in with IGO (refer below).

2021 Minyari Dome Project Exploration Programme

The expanded Minyari Dome Project CY 2021 exploration programme, which was commenced in May and was completed late December, included the following:

  • A significant DD and RC drill programme (42,666m) focused on the Minyari and WACA deposits with the following objectives:

    • Test for both extensions to and new zones of highgrade Minyari-WACA goldcopper mineralisation;

    • Update the Minyari-WACA Mineral Resource estimate; and

    • Upgrade the Minyari-WACA Mineral Resource JORC classification (i.e. increase the Indicated component of the resource).

  • Minyari-WACA project development Scoping Study, key components including;

    • Mining study (both open pit and underground);

    • Geotechnical evaluation; and

    • Obtain further sample material for metallurgical testwork.

  • Undertake a Minyari-WACA downhole electromagnetic (DHEM) survey to identify the location of potential highgrade sulphide rich breccias similar to the Havieron "Sulphide Crescent Zone";

  • A significant greenfield exploration programme, including RC drilling (10,530m), focused on delivering significant gold and/or copper discoveries within 4km of the existing Mineral Resources that can enhance the Minyari-WACA development opportunity. The key components of this greenfield exploration programme were:

    • Detailed Drone (UAV) Magnetic Survey - Survey with 20m line spacing to enhance deposit, prospect, and greenfield targeting via the identification of key lithologies, structures, and magnetic anomalies;

    • Gradient Array Induced Polarisation (GAIP) Survey - To identify IP chargeability (± resistivity ± conductivity) anomalies related to gold-copper sulphide mineralisation and also map certain key lithologies;

    • Surface Geochemical Programme - Systematic fine-fraction soil programme across significant areas of the Minyari Dome Project to generate further priority greenfield targets for drill testing in CY 2022; and

    • RC Drill Programme - 10,530m (43 RC drill holes) testing approximately 14 geophysical and/or geochemical (air core) greenfield targets.

The Company's Paterson Province dual exploration strategy strives to deliver both greenfield discoveries and increase brownfield gold and/or copper resources plus identify and evaluate potential mineral development projects. Future exploration activities within the Minyari Dome Project are complementary to this strategy.

2021 Minyari Dome Project Exploration Programme Results

During the Quarter further DD and RC drilling results (received for 60 drill holes including RC, DD-tails and DD drill holes for 16,460m), with results for Minyari continuing to return multiple high-grade gold and copper intersections, including further significant greenfield gold-copper discoveries outside the existing Minyari-WACA Mineral Resources. Antipa has engaged independent mining consultants Snowden Optiro to complete the Minyari and WACA Mineral Resource estimate update which is scheduled to be completed imminently.

Key highlights and significant drill results received during the Quarter are summarised below:

Minyari Mineral Resource Definition Drill Programme:

  • Further sixty Minyari and WACA deposit drill hole assays received during the Quarter returned significant high-grade gold and copper (± silver and cobalt) extending the potential size of the Minyari and WACA resources:
