Altair Minerals Locks Up 18km on Gold Shear That Already Triggered A$4B in Buyouts
Key Takeaways
- Altair Minerals has secured 29km² of adjoining permits at South Oko, increasing its Oko Shear Contact exposure by approximately 30% and bringing total strike coverage to 18km — equivalent to the combined strike previously held by G2 Goldfields and Reunion Gold.
- The Oko Shear Contact has already yielded 9.1Moz Au at 2.6g/t from just 6km of drilled strike, with Altair's 18km of exposure representing the largest undeveloped footprint on the structure.
- The same geological corridor triggered A$4B in combined takeovers in 2024–2026, with G2 Goldfields acquired for A$3B and Reunion Gold for A$1B, both now under G Mining Ventures.
- Altair's existing RC drilling programme, camp infrastructure, and geochemical sampling at SOKO mean new targets across the acquired permits are expected to be drill-ready within three months.
- The acquisition is structured as a staged option agreement with an upfront signing payment of US$175,000 already paid, preserving capital flexibility while securing a 48-month window to exercise full 100% ownership for US$4.5M.
Altair secures 29km² expansion at South Oko, cementing dominance on the Oko Shear Contact
Altair Minerals (ASX: ALR) has secured 29km² of critical adjoining permits at South Oko (SOKO), increasing its exposure to the Oko Shear Contact by approximately 30% and bringing its total strike coverage to approximately 18km. This positions Altair as only the third company to ever explore the Oko Shear Contact, following G2 Goldfields (acquired for A$3B in 2026) and Reunion Gold (acquired for A$1B in 2024), both now consolidated under G Mining Ventures (TSX: GMIN).
Altair’s 18km of strike coverage is now equivalent to the combined strike previously held by those two companies on the northern extension. The Greater Oko Project’s total footprint now stands at 457km², reaffirming its position as the largest gold exploration project in Guyana.

Why the Oko Shear Contact matters for gold investors
A greenstone shear contact is where two fundamentally different rock types meet: hard, rigid granite on one side and softer, more deformable greenstone on the other. During periods of geological compression, the rigid granite acts as a buttress, forcing all the strain into the ductile greenstone. That strain creates a network of shear corridors, and it is precisely within these corridors that gold-bearing fluids migrate and deposit metal, forming the structural framework that hosts tier-1 gold deposits.
The Oko Shear Contact is a proven example of this process at scale. Only approximately 6km of the structure has been drilled to date, yet those 6km have already produced 9.1Moz Au at an average of 2.6g/t Au (Measured + Indicated + Inferred).
Guyana adds a further layer of appeal for investors. It is the last pro-mining, politically stable country on the Guiana Shield, hosting the same Birimian Greenstone geology that has underpinned world-class gold discoveries across West Africa, including in Ghana, Ivory Coast, and Burkina Faso. Unlike those African counterparts, however, Guyana remains significantly underexplored.
To benchmark the peer group actively exploring across the Guiana Shield:
- G2 Goldfields / Reunion Gold: acquired by G Mining Ventures for A$3B and A$1B respectively
- OMAI Gold Mines: A$1.9B market capitalisation (as at 15 September 2026)
- Founders Metals: A$708M market capitalisation (as at 15 September 2026)
- Greenheart Gold: A$190M market capitalisation (as at 15 September 2026)
Altair’s 18km of strike exposure sits directly adjacent to 9.1Moz already discovered, representing a significant opportunity in a district that has already demonstrated it can produce tier-1 gold deposits.
How the expansion integrates with Altair’s active drill programme
Timing is a material part of this deal’s value. Unlike the northern SOKO targets, which took months to develop from scratch, Altair already has an execution-ready exploration team, camp infrastructure, active RC drilling, and geochemical sampling underway at SOKO. The company has indicated it expects new targets across the new permits to be developed in less than 3 months, with seamless integration into the current RC programme or a subsequent diamond drill programme.
South Oko trenching results have already returned intercepts of 10m at 10.15g/t Au, providing early confirmation of the structural gold system that the expanded RC programme is now targeting at depth.
The new permits were hand-selected based on four key geological criteria:
- Prospective geology units within a proven mineralised structural corridor
- Aeromagnetics identifying favourable hydrothermal structural conduits and iron-rich mafics
- Stream anomalies and position within the primary source area to alluvial gold workings
- Potential geochemical extensions to SOKO along an analogous structural setting
The acquisition also expands the “search space” at SOKO, meaning multiple discoveries can potentially be pursued in parallel rather than sequentially.
Faheem Ahmed, CEO, Altair Minerals
“We’ve now secured and established ourselves as the dominant player in the Oko district, with the most significant strike exposure to the globally emerging shear zone…”
“…meaning we are ready to commence work on these new permits immediately.”
Deal structure and payment terms
The acquisition is structured as a staged, option-based agreement, keeping upfront capital requirements modest while preserving flexibility. Altair has entered into a binding heads of agreement with the Vendor Parties (Henry Alphonso, Lorenzo Alphonso, Clinton Alphonso, and Vincent Thakur), who hold a 100% interest in the new permits.
Pursuant to the agreement, Altair holds an exclusive option to acquire a 100% interest in the permits. Upon exercise and satisfaction of the Earn-In Agreement with Adamantium Exploration Inc., Altair anticipates granting operational rights to the Greater Oko Joint Venture Company (70% Altair / 30% Adamantium).
The Greater Oko Joint Venture structure, with Altair holding a 70% operating interest alongside Adamantium Exploration’s 30%, was established through an earlier consolidation process that brought the project’s core permits under unified management.
The payment schedule is as follows:
| Stage | Trigger | Amount (USD) | Notes |
|---|---|---|---|
| Signing Payment | 60-day due diligence commencement | US$175,000 | Already paid |
| Completion Payment | Satisfaction of due diligence | US$1,075,000 | Commences 12-month option period |
| Option Retention (annual) | Each 12-month anniversary post-commencement | US$650,000/year | Retains option for up to 48 months |
| Option Exercise | Any time within 48 months of commencement | US$4,500,000 | Grants 100% beneficial interest |
| Production Payment | 12 months post-commercial production (permits T-32/MP/000 and T-32/MP/001 only) | US$4/oz gold produced | Annual payment, applicable to two specified permits only |
The structure allows Altair to control 18km of high-priority strike for a relatively modest upfront commitment, with the optionality to exercise full ownership or exit within a 48-month window.

Investment thesis: Altair as the prime explorer in a district that has already produced A$4B in takeovers
The strategic picture here is straightforward. Altair has locked up the priority remaining permits on the Oko Shear Contact, the same structure that produced 9.1Moz Au and triggered A$4B in combined takeovers over just two years. Only 6km of strike has been drilled on the adjoining northern extension, while Altair’s total strike exposure now reaches 18km.
CEO Faheem Ahmed has noted that SOKO continues to demonstrate “tremendous potential for discovery” as the drill programme progresses. With new targets across the acquired permits expected to be developed within 3 months for integration into the current or a subsequent drill programme, the next material catalysts from this district are approaching.
