Proactive Investors - Antipa doubles gold mineralisation strike at Minyari Dome’s GEO-01 discovery

Antipa Minerals Ltd (ASX: AZY) has completed 2024 Phase 1 reverse circulation (RC) drilling at GEO-01 gold discovery of the 100%-owned Minyari Dome Gold-Copper Project in the Paterson Province of Western Australia with assay results doubling the gold mineralisation strike.

A total of 81 holes for 13,122 metres were drilled in the recently completed Phase 1 program at the GEO-01 anomaly, with assays now returned from the first 19 holes.

The latest results, from 13 holes for 2,330 metres of drilling, have identified new zones of near-surface gold mineralisation at GEO-01. The first six RC holes previously returned thick zones of near-surface, potentially open pittable, high-grade gold mineralisation.

These results have increased the main zone of GEO-01 mineralisation to 500 metres along strike (previously 250 metres) and up to 190 metres across strike (previously 150 metres). The mineralisation remains open in most directions, presenting a significant potential maiden resource opportunity.

Best results are:

  • 26 metres at 0.7 g/t gold from 16 metres down hole in 24MYC0449, including 11 metres at 1.2 g/t from 17 metres and 1 metre at 1.3 g/t from 38 metres;
  • 17 metres at 0.5 g/t gold from 49 metres down hole in 24MYC0454, including 8 metres at 1.0 g/t from 53 metres and also including 2 metres at 3.2 g/t gold and 0.04% copper from 55 metres.

Minyari Dome resource locations, scoping study open pit limits, prospect locations for GEO-01, Minyari North, Rizzo and WACA East, and contoured maximum down-hole gold drill results.

GEO-01 is around 1.3 kilometres south of the 1.5-million-ounce Minyari gold-copper deposit. The current round of results returned increased the prospective mineralised footprint to 700 metres by 500 metres.

“Maiden resource opportunity”

Antipa believes the large scale of the GEO-01 gold anomaly with a footprint similar in size to the flagship Minyari deposit, and it remains open in several directions, presents “a substantial near surface potential maiden resource opportunity”.  The CY2024 Phase 1 exploration drilling program was designed to deliver a maiden mineral resource estimate (MRE) at the GEO-01 discovery and to target new gold-copper discoveries within multiple high-priority target areas including three Pacman geophysical targets.

Phase 1 had originally been scheduled for a total of 74 drill holes for 13,770 metres, comprising 71 RC holes for 10,620 metres and three diamond core drill holes for 3,150 metres.

However, given the positive results to date, the RC program was expanded to 81 holes for 13,122 metres, with the addition of 10 RC drill holes for 2,502 metres. The RC drilling program was completed yesterday.

Antipa managing director Roger Mason said, “This year’s Phase 1 drilling at GEO-1 has been designed to deliver on what we believe to be a significant maiden resource opportunity.

“Today’s results have further emphasised this by adding significantly to the known zones of near-surface gold mineralisation and doubling the strike extent of the main zone of gold mineralisation. 

“Notably, drill hole 24MYC0462 intersected significant gold mineralisation within 6 metres of the end-of-hole, warranting re-entry to test the full mineralised extent. 

“As a direct result of the positive outcomes from the assay results received to date the decision was made to expand the program to 87 holes for 12,750 metres. We expect the next round of laboratory assay results to be returned in the coming weeks.”
