Antipa Minerals Limited announced further assay results for the 2021 drill programme on its 100% owned, 144km square Minyari Dome Project in Western Australia's Paterson Province. The Project is located within 35km of Newcrest Mining's (Newcrest) Telfer goldcoppersilver mine and mineral processing facility and 54km along strike from Greatland GoldNewcrest's Havieron goldcopper development project. Assay results have now been received for 100% of the MinyariWACA 2021 resource infill and resource extensional drilling programme, with results increasing the potential size of the Minyari and WACA resources and enhancing the project development opportunity.

Outstanding assays from the final 6,440m of drilling from the 2021 program relate to greenfield drilling. The assays received cover the final four Minyari reverse circulation (RC) drill holes and six (five Minyari and one WACA) diamond core (DD) drill holes in total (4,760m of the 42,110m drilled), which demonstrate favourable compatibility with the current Minyari and WACA Mineral Resource domains and have discovered significant additional highgrade goldcopper mineralisation outside the limits of the Minyari and WACA resources. At Minyari, highgrade gold with copper, silver and cobalt mineralisation which occurs along 500m of strike across a horizontal width of up to 300m, has now been extended down to 670m below the surface, and mineralisation remains open in several directions including down plunge.

During 2021 mineralisation has now been discovered immediately east, west, and both up plunge to the southeast and down plunge to the northwest, including significant highgrade breccia style mineralisation. At WACA, highgrade mineralisation which occurs along 650m of strike across a horizontal width of up to 100m, has now been extended down to 510m below the surface, and mineralisation remains open in several directions. During 2021 mineralisation has been discovered in both the shallow and deeper regions of WACA, with drill results confirming a moderate northwesterly mineralisation plunge similar to Minyari.

The drill results received to date significantly have: substantially extended zones of very highgrade goldcoppersilvercobalt mineralisation outside the current Minyari and WACA deposit Mineral Resource estimate boundaries. This would be expected to have a material positive impact on the existing MinyariWACA 2017 Mineral Resource Estimate, which combined host 723koz gold at 2.0 g/t and 26kt copper at 0.24%, which is in the process of being updated; discovered new highgrade goldcopper mineralisation in several areas with mineralisation remaining open down plunge, along strike and variously open across strike to the east and west; and further confirmed that highgrade mineralisation is commonly associated with sulphide matrixed breccia zones similar to the Havieron goldcopper style of mineralisation, with Minyari drilling at depth confirming continuity of moderate northwest plunging "pipe" like thick highgrade breccia mineralisation which remains open at depth providing further exciting exploration upside. Minyari-WACA DHEM Programme: Due to the correlation between highgrade mineralisation and (conductive) sulphide rich breccias a downhole electromagnetic (DHEM) survey was completed during December for a selection of diamond core drill holes at both Minyari (four holes) and WACA (one hole).

The aim of the DHEM survey was primarily to identify conductivity targets down dip and to a lesser degree along strike/downplunge at both Minyari and WACA. The processing and interpretation of the DHEM data has recently been completed and has identified several conductivity targets (40 to 50m in size) proximal to the Minyari mineralisation, including on its northern extremity, and one conductivity target (50m in size) down plunge of the WACA mineralisation. The results of the DHEM survey are compatible with the findings of the 2021 drill programme that the Minyari and WACA highgrade goldcopper mineralisation is hosted by sulphide rich breccias which lack interconnectivity in the form which DHEM requires for it to be an effective exploration tool.

However, breccia mineral systems can rapidly change character and so DHEM will continue to be deployed as a targeting tool. Assay results for the remainder of the 2021 drill greenfield programme (6,440m) are expected to be received within the next three weeks which, in conjunction with other data, will form the basis for further followup drill testing in the 2022. A significant Minyari Dome Project soil geochemical sampling programme covering approximately 92km square (826 samples) was completed late last year.

The soil assay results are expected to be received this month and will be analysed in conjunction with the 2021 greenfield drill hole data and other data sets to rank existing and new greenfield exploration targets for further direct drill testing in the 2022.
