Altair Minerals Gold Exploration Potential Grows with 17km Discovery Zone

Major Geochemical Discoveries Expand Altair's Gold Exploration Potential by 17 Kilometers

Altair Minerals Limited (ASX: ALR) has significantly expanded its exploration footprint at the Greater Oko Project in Guyana. The Altair Minerals gold exploration potential has grown substantially with new stream sediment and BLEG (Bulk Leach Extractable Gold) data revealing 17 kilometres of additional high-priority gold targets across the underexplored greenstone belt.

The comprehensive dataset, acquired from the Guyana Geology and Mines Commission (GGMC), has identified multiple new geochemical anomalies containing gold values over 10 times background levels. Furthermore, standout results include 4,370 ppb Au at North Peters and 2,140 ppb Au at South Oko.

These discoveries not only validate the company's existing targets but also define three entirely new regional prospects with immediate drill-ready potential.

Exceptional Results Define Multiple High-Grade Zones

South Oko: 5-Kilometre Anomalous Corridor

According to the announcement, the South Oko prospect has delivered the most consistent set of stream sediment anomalies across the entire project area. The results define a major anomalous zone spanning approximately 5km wide and 4km long.

The geochemical signatures align precisely with the structural corridor of the Oko Shear. This is the same geological formation that hosts 9 million ounces of gold resources at neighbouring deposits.

Key South Oko Results:

• 2,140 ppb Au (Stream Sediment Sample 7215)
• 1,510 ppb Au (Stream Sediment Sample 1754)
• 649 ppb Au (Stream Sediment Sample 7209)
• 655 ppb Au (BLEG Sample 7215)
• 465 ppb Au (BLEG Sample 7244)

For context, the stream sediment sample directly above the 6-million-ounce Oko West deposit returned 1,590 ppb Au with a BLEG result of 70 ppb Au. Consequently, Altair's results appear highly encouraging from a comparative perspective.

North Peters: 6-Kilometre Expanded Target Zone

At North Peters, the new data has expanded the prospective target zone over 6 kilometres. Multiple high-grade anomalous zones have been identified over 2km from the historic drilling area.

The discovery of samples returning over 4,000 ppb Au suggests potential for a larger mineralising system than previously understood.

Outstanding North Peters Results:

• 4,370 ppb Au (Stream Sediment Sample 3017)
• 4,300 ppb Au (Stream Sediment Sample 1738)
• 1,070 ppb Au (BLEG Sample 3017) – highest BLEG value in database
• 767 ppb Au (Stream Sediment Sample 0954)
• 644 ppb Au (Stream Sediment Sample 3133)

Three New Regional Targets Identified

The dataset has also defined three additional regional targets. Each demonstrates 100% strike rate for highly anomalous gold values exceeding five times background levels.

These regional targets provide a strong pipeline of multiple targets for systematic follow-up exploration. In addition, they support Altair's goal of developing Greater Oko into a multi-deposit project.

Understanding BLEG Analysis: A Key Exploration Tool

Bulk Leach Extractable Gold (BLEG) is a specialised geochemical technique used to detect gold in stream sediments and soil samples. This method involves leaching samples with cyanide to extract fine gold particles and soluble gold compounds that conventional analysis might miss.

Why BLEG matters for investors:

• Detects gold that may not be visible in standard stream sediment analysis
• Provides indication of nearby gold deposits through transported material
• Helps define drill targets in early-stage exploration
• Proven technique in similar Guiana Shield gold discoveries

However, the combination of high stream sediment values with corresponding elevated BLEG results strengthens the geological case for significant mineralisation in the area.

Project Scale Advantage: An Irreplaceable Asset

The Altair Minerals gold exploration potential is significantly enhanced by the 590km² Greater Oko Project. This represents what the company describes as a landmark consolidation opportunity in one of the world's most prospective but underexplored greenstone belts.

Due to Guyana's fragmented exploration permit system (typically 1-5km² per block), this scale of contiguous tenure is considered irreplaceable.

Comparative Project Analysis:

The Greater Oko Project provides ~16 kilometres of Oko Shear strike coverage. This significantly exceeds both competitor projects combined, while maintaining proximity to proven multi-million-ounce discoveries.

Accelerated Exploration Programme Underway

"This dataset has been a critical first step in validating and evaluating the expansion target potential at South Oko and North Peters. Most intriguingly, the stream sediments and BLEG anomalies at South Oko are precisely within the structural corridor of mineralisation we expect."

Faheem Ahmed, CEO

Current Exploration Activities:

• Third exploration team deployed to expedite South Oko trenching programme
• Auger and soil sampling continuing across priority targets
• First batch of extensional soil samples delivered to laboratory with assays pending
• Second batch of samples scheduled for dispatch

Furthermore, the company recently completed a cornerstone placement to fund expanded exploration activities. This enables multiple field teams to operate simultaneously across the project.

Investment Thesis: Exceptional Discovery Potential

The Altair Minerals gold exploration potential presents a compelling investment opportunity based on several key factors:

Scale and Location Advantages

The project offers 590km² of contiguous tenure in a proven gold district. It is adjacent to $1+ billion gold assets with established infrastructure.

Most importantly, it provides 16km of Oko Shear coverage – the most extensive in Guyana.

Geological Validation

The project demonstrates multiple high-grade anomalies over 10x background levels. There are 17km of new target zones identified through systematic database analysis.

For instance, these zones feature the same geological formations as neighbouring multi-million-ounce deposits.

Exploration Momentum

Multiple field teams are accelerating ground-based programmes. There is a pipeline of assay results expected from ongoing sampling.

Additionally, the company maintains a systematic approach to target generation and prioritisation.

Market Context

Guyana is emerging as a premier global gold jurisdiction. There is a proven track record of recent major discoveries in the district.

The region benefits from political stability and a mining-friendly regulatory environment.

Why Should Investors Monitor Altair Minerals?

The combination of Altair's exceptional project scale, high-grade geochemical anomalies, and proximity to billion-dollar gold assets positions the company as a standout opportunity. With 17 kilometres of new target zones now defined and multiple exploration teams advancing ground-based programmes, the Altair Minerals gold exploration potential appears well-positioned.

The company can capitalise on one of the most significant land consolidations in Guyana's mining history. The systematic approach to exploration, supported by government geochemical databases and experienced technical teams, provides multiple pathways to discovery success.

As exploration results continue to emerge from the ongoing programmes, investors should monitor Altair's progress closely. The exceptional scale and quality of the Greater Oko Project warrant attention.

What Makes This Discovery Significant?

Altair Minerals has positioned itself as the largest landholder along the prolific Oko Shear zone in Guyana. With 17km of newly identified gold targets and proximity to 9 million ounces of neighbouring gold resources, the company offers exceptional discovery potential.

However, the company operates in one of the world's most promising gold districts. With systematic exploration programmes underway and multiple high-grade anomalies defined, the Altair Minerals gold exploration potential represents a significant opportunity for investors seeking exposure to Guyana's emerging gold sector.

Is Altair Positioned for Major Gold Discovery Success?

With 17 kilometres of newly identified high-grade gold targets and 590km² of strategic tenure along Guyana's prolific Oko Shear zone, Altair Minerals represents exceptional discovery potential in one of the world's most promising gold districts. The company's systematic exploration approach, multiple field teams, and proximity to 9 million ounces of neighbouring resources position it uniquely for significant developments.
