Altair Minerals Limited Investment Report

Altair Minerals Limited (ASX: ALR) is an Australian mineral exploration company focused on investing in the resource sector through direct tenement acquisition, joint ventures, farm-in arrangements, and new project generation. The company’s flagship Greater Oko Project in Guyana is a massive 592 km² landholding with scope to expand to ~3,500 km², positioned just 1.5 km from GMIN’s 5.9Moz Oko West discovery, alongside its Olympic Domain tenements in South Australia

Recent Updates:

•  Largest Geochemical Program on Oko Shear Zone Commences (Sept 2025): Altair has commenced the largest geochemical program ever on the Oko Shear Zone, covering 15 km at South Oko with 778 soil samples, >3 km trenching, mapping & grab sampling. Initial assays expected November 2025. Key targets E1 & W1 anomalies (>100 ppb Au, largest magnetic high on shear) and new S1 & S2 prospects. Program designed to advance South Oko to drill-ready stage ahead of maiden drilling with North Peters.
• Guyana: Discovery-Ready with Dual Pipelines (Aug 2025): Altair is advancing two complementary pipelines in-country. At South Oko, Tier-1 scale gold-in-soil anomalies have been defined at W1 (2 km) and E1 (1.3 km) larger than the anomaly that led to G Mining’s 5.9 Moz Oko West discovery. No modern drilling has been completed to date. The initial work program prioritises structural mapping, geochemistry and geophysics to define firstpass drill corridors. At North Peters, historic auger and diamond drilling already demonstrated broad zones of gold mineralisation, including a 2005 foreign estimate of 251 koz @ 4.91 g/t Au (nonJORC) and multiple step-out long, high-grade intercepts confirming depth continuation of the historic resource.. Together, South Oko and North Peters provide a rare dual-track path to discovery.
• Deal Secured: Path to 70% of Greater Oko (Aug 2025): Altair has executed a staged earn-in over a 592 km² land package
  (expandable to ~3,500 km²). The agreement includes a 90-day exclusivity, staged spend- and cash-based milestones, and a proposed A$3.2M placement at A$0.004 to fund initial programs.
• Insider Buy: Director Adds On-Market (11 Aug 2025): Non-Executive Director Bilal Ahmad purchased 6.0M shares for A$60k. He now holds 272.0M shares and 132.85M unlisted options.
• Leadership Strengthened (15 Aug 2025): Appointment of Rich Munson as in-country Executive Director and Country Manager for Guyana. Munson previously advanced the Toroparu Project from first drill hole to 7–10 Moz Au and helped raise US$500M for development. His experience in government liaison, permitting, logistics and financing directly accelerates Altair’s Greater Oko strategy.
