Altair Minerals Gold Discovery in Guyana Expands W1 Target

Breaking: Altair Minerals Gold Discovery in Guyana Delivers Massive Soil Anomaly Expansion

Altair Minerals Limited (ASX: ALR) has delivered exceptional exploration results that have dramatically expanded its flagship W1 target at the South Oko project in Guyana. The latest soil sampling program has doubled the size of the main soil anomaly, establishing it as the largest coherent >100ppb Au soil anomaly identified to date on the highly prospective Oko Shear Contact. This significant development positions the altair minerals gold discovery in guyana as a potentially transformative moment for the company and its investors.

Breaking: W1 Target Becomes Major Discovery Prospect

The infill and extensional soil assay results have transformed the W1 target into a 2.2km strike length anomaly with widths up to 800 metres. This represents a significant milestone for Altair, positioning the company alongside major regional players in one of the world's most underexplored gold districts.

Furthermore, the expansion demonstrates systematic exploration success that could lead to a major resource discovery. The results validate the company's methodical approach to target development whilst substantially increasing the prospective footprint.

Key Highlights from Latest Results

The current batch of results has delivered impressive gold concentrations that reinforce the discovery potential:

• 888 ppb Au peak soil result (sample SK-SL-26-00737) – one of the highest recorded
• 571 ppb Au secondary peak (sample SK-SL-26-00781)
• 203 soil samples processed from current batch
• 248 additional samples still pending assay results
• Anomaly remains open to the east and potentially westward under laterite cover

The results validate the 2022 vendor-conducted program while substantially expanding the anomalous footprint, creating what CEO Faheem Ahmed describes as a "prominently developed and high-priority drill target."

In addition, the systematic nature of the sampling program has provided confidence in the continuity and scale of the mineralised system. The coherent nature of the anomaly suggests a substantial gold source beneath the surface.

CEO Faheem Ahmed commented:
"The width, strike length and continuity of the SOKO soil anomaly now defined through systematic sampling are analogous to – if not more compelling than – the geochemical footprints that have led to adjoining world class discoveries in the district."

Understanding Soil Geochemistry: The Foundation of Gold Discovery

What are soil anomalies and why do they matter?

Soil geochemistry involves analysing the chemical composition of subsurface soils to detect trace elements that may indicate underlying mineralisation. In gold exploration, soil samples are typically collected from the B-Horizon (20-50cm below surface) to avoid contamination from surface organic matter.

Parts per billion (ppb) measurements represent the concentration of gold particles in soil samples. Background levels typically range from 1-10 ppb, while anomalous values exceed 50-100 ppb. The 888 ppb result at South Oko represents gold concentrations nearly 90 times background levels, indicating proximity to a significant gold source.

However, interpreting soil geochemistry requires understanding of local geological conditions and potential contamination sources. The systematic approach employed by Altair addresses these challenges through consistent sampling protocols and statistical analysis.

Why this matters to investors

Large-scale, coherent soil anomalies like the W1 target often overlie substantial gold deposits. The size and intensity of Altair's anomaly is directly comparable to those that led to major discoveries in the region, including the neighbouring 5.9Moz Au Oko West deposit.

Consequently, the expansion of the soil anomaly significantly increases the probability of discovering a substantial gold resource. The coherent nature and high-grade results suggest the presence of a major mineralised system that warrants immediate advancement to drilling.

Strategic Positioning in World-Class Gold District

Altair's 590km² contiguous landholding positions the company in the heart of Guyana's emerging Birimian greenstone belt – the same geological formation that hosts world-class gold deposits across West Africa. The Oko Shear Contact has already delivered over 9Moz Au in recent grassroots discoveries, establishing the region as a Tier-1 gold district.

The company's strategic location provides access to proven geological structures whilst maintaining significant exploration upside. Furthermore, the established infrastructure and supportive regulatory environment in Guyana enhance the potential for rapid project development.

Regional Context and Peer Comparisons

The company's proximity to established discoveries, combined with the scale of the W1 anomaly, positions Altair as a potential major player in this rapidly developing gold district.

For instance, the success of neighbouring projects demonstrates the exceptional discovery potential within this geological setting. The systematic approach to exploration employed across the region has consistently delivered world-class discoveries.

Next Phase: From Discovery to Drilling

Altair's systematic approach to target development includes multiple phases designed to de-risk the drilling program whilst maximising discovery potential.

Immediate Priorities (Q2 2026)

The company has outlined a clear pathway to drilling that addresses both technical and commercial considerations:

1. Complete soil sampling program – 248 samples pending results
2. Extended trenching program – targeting 6+ metre depths
3. RAB/auger drilling – testing duricrust-covered areas
4. W3 target delineation – potential amalgamation with W1

Path to Drilling

The progression toward diamond drilling follows established best practices for gold exploration in tropical environments:

• Trench 6A extension showing favourable geology with sharp intrusive contacts
• Enhanced trench depths targeting saprolite/saprock horizons
• Systematic geological mapping aligning with geochemical signatures

The company reports that Trench 6A has transitioned from mafic intrusive and sheared mafic volcanic units to volcaniclastic sediments, encountering a sharp horizontal contact with an intermediate intrusive surrounded by an alteration halo containing phenocrysts.

However, the most significant development is the clear geological control observed in trenching, which provides confidence in targeting for the upcoming drilling program. The structural complexity suggests multiple mineralisation events that could enhance the overall resource potential.

Investment Thesis: Tier-1 Discovery Potential

Why the W1 Anomaly Represents Exceptional Value

The combination of scale, geological setting, and systematic exploration success creates a compelling investment proposition for investors seeking exposure to potential tier-1 gold discoveries.

Scale and Coherence: The 2.2km x 800m anomaly represents one of the largest coherent gold soil signatures identified on the Oko Shear Contact – the same structural corridor hosting multiple major discoveries.

Geological Setting: The pronounced geochemical contrast across the Oko Shear Contact mirrors successful discovery patterns at neighbouring deposits, suggesting similar mineralisation processes.

Exploration Upside: With the anomaly remaining open to the east and potentially masked by laterite cover to the west, the true extent of the W1 target may be significantly larger than currently defined.

Furthermore, the systematic exploration approach reduces discovery risk whilst maintaining significant upside potential. The methodical progression through soil sampling, trenching, and drilling follows industry best practices for maximising discovery success rates.

Financial and Strategic Advantages

The company's current positioning offers several advantages that enhance the potential for investor returns:

• Undervalued positioning compared to regional peers
• First-mover advantage in underexplored Birimian terrane
• Systematic approach reducing exploration risk
• Experienced team including ex-Reunion Gold personnel

In addition, the company's financial position provides sufficient runway for advancing the project through to drilling, whilst maintaining flexibility for additional target development across the broader landholding.

Why Investors Should Follow Altair Minerals

The expansion of the W1 target reinforces why Altair deserves attention as a potential major discovery story in Guyana's emerging gold district. The company has successfully validated and expanded upon previous exploration work, demonstrating both technical competence and the substantial mineral potential of the Greater Oko Project.

Compelling Tracking Points

The investment case for Altair centres on multiple near-term catalysts and strategic advantages that differentiate the company from typical exploration investments.

Near-term Catalysts:
