Antipa Minerals Limited announced exploration results for the Citadel Joint Venture Project CY 2021 Exploration Programme (2021 Exploration Programme) and advise that the CY 2022 Exploration Programme has been agreed with Rio Tinto Exploration Pty Limited (Rio Tinto). The 2021 Exploration Programme, operated by Rio Tinto, comprised the following activities: A 24,530metre reverse circulation (RC) (14,871m) and diamond core (DD) (9,658m) drill programme focused on: the Magnum Dome area (10,876m), which hosts the Calibre and Magnum gold coppersilver combined Mineral Resources of 2.4Moz of contained gold, 162kt of contained copper and 1.8Moz of contained silver (for tonnage and grade details see the table further below in this release), and the Corker deposit; and the Rimfire area together with select regional targets (13,654m). Assay results have been received for 17,697m (RC 14,266m and DD 3,431m); Preliminary metallurgical testwork and geotechnical evaluations (including 291m of geotechnical drilling) at Calibre (ongoing); Preliminary appraisal work in respect of early stage conceptual project development parameters at the Calibre deposit (ongoing); Continuation of the GAIP survey programme across prospective structural corridors of the Citadel tenements, prioritising areas that have had limited or no testing of the basement by drilling; Rimfire detailed aeromagnetic survey covering 110km2 with orthogonal survey lines; and Ongoing processing and interpretation of geophysical and drill hole data, together with Calibre deposit and Magnum Dome modelling to identify further priority target areas which may support a potential Mineral Resource update. Drilling at Calibre extended the goldcopper mineralisation beyond the southern limits of the existing 2.1Moz gold and 104kt copper Mineral Resource by up to 100m to the west and east and also beneath the southern region of the resource by up to 150m. Based on a step out drill section 200m south of the resource, the Calibre mineralisation remains open but apparently less well developed. Available assay results can be found in Table 1 with results for several holes pending. Appraisal work in respect of Calibre early stage conceptual project development options is ongoing and includes geotechnical drilling and metallurgical test work. The Rimfire intrusion has developed a very largescale precious and base metal mineral system which extends across an area of up to 6 km in diameter located approximately 25km southeast of Rio Tinto's Winu coppergoldsilver deposit. The 2021 Rimfire greenfield drill programme largely targeted areas with anomalous magnetic signatures and goldcopper mineralisation from the 2020 RC drilling. Drilling at Rimfire has identified two zones of significant goldcoppersilver±tungsten mineralisation 4.4km apart, Sundance and Hangfire, for follow up drilling, both of which remain open in all directions. Mineralisation at the Sundance target is related to a possible domal magnetic feature which extends across 1.5km at Rimfire northeast and mineralisation at the Hangfire target is related to a possible folded magnetic feature which extends across 500m at Rimfire southeast. Rimfire mineralisation is predominantly hosted by metasediment and mafic intrusives. Assays for 14 of the 15 RC and 2 of the 6 DD drill holes completed at the Rimfire area in 2021 have been received. Encouragingly, a number of these very widely spaced (200 to 1,000m), commonly vertical holes, returned a number of significant intersections with available assay results including maximum grades of 7.73 g/t gold, 5.0% copper, 9.03 g/t silver and 0.54% tungsten, with results for several holes pending. Interestingly Sundance DD hole RFRN0005 intersected massive sulphide (pyrrhotite >> chalcopyrite > pyrite) breccia style goldcopper mineralisation which is magnetic and highly conductive. This breccia mineralisation had not been detected by AEM surveys over the area and so in order to enhance drill targeting a detailed Rimfire aerial magnetic survey was completed this year and ground EM surveys are being considered for 2022. Large regions of magnetic anomalies at Rimfire, including many under shallow cover of less than 30m, remain untested with the recent drill results highlighting the exploration potential for a material discovery. Interpretation, 3D modelling and targeting of the Rimfire 2021 aerial magnetic survey is ongoing. Eight broad spaced drill holes (one DD and seven RC holes) were completed at the Magnum Shear target, which is located between the Magnum and Calibre deposits, with drilling intersecting further narrow highgrade goldcopper mineralisation along a 1km strike with maximum grades of 6.78 g/t gold, 1.7% copper, 7.51 g/t silver and 0.13% tungsten. The prospect is currently under review. Two DD holes were completed at Magnum North testing for strike extensions to the Magnum gold coppersilver Mineral Resource, assay results are pending. One RC hole was successfully completed at Citadel Northeast which is a conceptual target for Nifty style highgrade copper mineralisation (i.e. structurally disrupted fold nose within black shales) located approximately 5km northeast of the Calibre deposit and beneath 120m of cover. The reconnaissance vertical RC hole intersected significant lowgrade copper mineralisation with 16.0m at 0.09% copper including 2.0m at 0.29% copper which is considered highly encouraging and the prospect is currently under review. Four very widely spaced (200 to 700m) vertical RC holes were completed at Boxer which is a +1,500m along strike x 900m wide IP chargeability anomaly located within a fertile structural trend situated 15km southeast from Rimfire. No significant mineralisation was intersected in the metasediments which are below 70m of cover, with black shales hosting low levels of disseminated to fracture pyrite potentially explaining the IP response. However, the only drill hole located on the western side of the IP anomaly BOXR0003 intersected a 22m zone of moderate to strong quartz veining with minor sulphides (pyrite >> pyrrhotite >> chalcopyrite). The prospect is currently being reviewed, with a followup deeper penetrating IP survey (e.g. PoleDipole IP) under consideration. Drill holes completed at Magnum East, Trigger, Ballstein and Le Tigre each returned narrow intersections with lowgrade gold and/or copper ± silver and tungsten mineralisation, whilst drill holes completed at the Noosa, Detachment and Hansel targets did not return any significant intersections (Tables 1 and 2). No follow up exploration is planned for these targets.
