Altair Minerals Limited (ASX: ALR), an Australian Securities Exchange-listed company focused on resource sector investments, with key projects including the Greater Oko Project in Guyana and the Olympic Domain Project in South Australia, has announced a significant milestone in its Greater Oko drilling programme. The company has now surpassed 10,000 metres of combined drilling across its South Oko (SOKO) and North Peters (NP) targets. This extensive drilling is rapidly advancing targets at SOKO, supported by promising geochemical results including a high-grade in-situ grab sample of 32.98g/t gold.
Reverse Circulation (RC) drilling at South Oko continues to progress, with geological logging indicating quartz veining, alteration, and sulphides across three distinct structural corridors, including a newly defined Eastern Corridor. The 32.98g/t gold grab sample, taken from the floor of Trench TR-W1-06, is particularly compelling as it extends a high-grade shear zone identified previously. Furthermore, first-pass soil sampling at a new Parallel Shear Target, approximately four kilometres west of W1, has returned highly anomalous results up to 1,669ppb (1.67g/t) gold, alongside a continuous 300-metre wide zone ranging from 59-201ppb gold.
Despite these promising developments, Altair acknowledged country-wide assay delays in Guyana due to equipment failures and flux shortages at ISO-certified laboratories. In response, approximately 5,000 duplicate samples have been sent to Suriname for QA/QC validation to explore additional laboratory options. Maiden assays for the North Peters diamond drilling are anticipated by the end of November, with SOKO RC assays for the northern W1 target expected within four to five weeks. An additional diamond drill rig has also been secured for SOKO, set to be mobilised in early 2027, to facilitate deeper testing and rapid follow-up on identified mineralisation.
