What is the significance of the 30,000m drilling programme started by Altair Minerals (ASX:ALR)?

Altair Minerals has launched its inaugural 30,000-metre discovery campaign at the Greater Oko Project in Guyana, marking a major transition from desktop review to active field operations. The 12-month programme is split equally between diamond and Rotary Air Blast drilling to test both high-grade targets and regional scalability.

Why is the North Peters prospect a key focus for Altair Minerals (ASX:ALR)?

North Peters is a priority because recent reviews of historical data uncovered high-grade trenching results, such as 16.5m @ 9.68g/t Au, that remain open at their boundaries.

What makes the Greater Oko Project landholding unique in Guyana?

Altair Minerals controls a 590km² contiguous landholding, which is the largest in Guyana’s history and nearly impossible to replicate due to the country's typically fragmented permit ownership. This vast area covers roughly 15km of the prolific Oko Shear, a geological structure where neighbours have already defined over 9 million ounces of gold.

How does the takeover of Oko-Ghanie by GMining Ventures affect Altair Minerals (ASX:ALR)?

The $3 billion takeover of the adjoining Oko-Ghanie Project by GMining Ventures (following a previous $1 billion deal in the area) positions Altair as the last major independent explorer in the Oko district.

What is the difference between the South Oko and North Peters targets?

North Peters is viewed as a near-term opportunity to validate high-grade historic results and test immediate extensions. In contrast, South Oko (SOKO) is considered a "Tier-1 virgin discovery" opportunity, featuring a large, untested geochemical anomaly on the regional structural system.

What are the main bull and bear points for Altair Minerals (ASX:ALR) after this news?

The bull case rests on Altair's massive, strategic landholding and the high-grade historical hits which suggest significant gold is present. The bear case involves the high risks inherent in greenfield exploration, where there is no guarantee that drilling will result in a commercially viable resource.

What are the key operational risks for Altair Minerals in Guyana?

While Guyana is a pro-mining jurisdiction, Altair faces the technical challenge of exploring through "duricrust" (a hard crust that masks soil geochemistry), which has historically hindered discoveries.

Altair Minerals launches 30,000m Guyana drill program

Written by Brie CarterPublished Apr. 14 2026Last Updated Apr. 14 2026

Altair Minerals (ASX:ALR) commenced its inaugural 30,000-metre drilling programme at the Greater Oko Project.

The 12-month discovery campaign consists of 15,000m of diamond drilling and 15,000m of rotary air blast drilling, primarily split between the high-grade North Peters prospect and the Tier-1 scale potential of South Oko.

The programme's scope has already expanded following the uncovering of exceptional historic trenching results at North Peters.

Data reveals significant mineralisation, including 16.5m @ 9.68g/t Au and 39.0m @ 3.78g/t Au, with many trenches remaining open at their boundaries.

The results suggest a robust north-west-to-south-east mineralised corridor spanning 450 metres that remains largely untested by previous drilling.

Altair’s 590km² contiguous landholding is the largest in Guyana’s history, a strategic advantage in a region typically characterised by fragmented permits.

The company finds itself in a unique position following the recent $3 billion takeover of the adjoining Oko-Ghanie Project by GMining Ventures.

The consolidation leaves Altair as the last major independent exploration opportunity on the prolific Oko Shear, where adjacent operators have already defined over 9 million ounces of gold.

CEO Faheem Ahmed noted that the programme represents a "step-change" for the company, with three drill rigs expected to be operating simultaneously by the end of April.

At the time of reporting, Altair Minerals' share price was $0.032.
