Gateway Mining Uncovers 90km of Untapped Shear Zones at Yandal Gold Project
Gateway Mining has identified approximately 90 kilometres of previously untested shear zones at its Yandal Gold Project in Western Australia, setting the stage for significant new gold exploration. The company plans major drilling campaigns in the coming months to unlock this potential.
- Discovery of 90km of new shear zones via recent geophysical surveys
- Shear zones include Mustang, Great Western Splay, and Nabberu structures
- Minimal historical exploration on these newly identified zones
- Ongoing surface sampling and geophysical programs underway
- Planned aircore drilling in October and diamond drilling at Dusk ‘til Dawn in November
Gateway’s Strategic Move in Yandal
Since acquiring the 100%-owned Yandal Gold Project in late June 2025, Gateway Mining Ltd has rapidly advanced exploration efforts, revealing a game-changing geological context. Recent high-resolution gravity and aeromagnetic surveys have delineated at least 90 kilometres of previously unrecognised shear zones, a discovery that significantly expands the prospective footprint for gold mineralisation in this prolific Western Australian greenstone belt.
New Shear Zones – Mustang, Great Western, Nabberu
The newly identified shear zones, Mustang, Great Western Splay, and Nabberu, are interpreted as major secondary splays off the primary 75km-long Celia Shear Zone. These structures have seen virtually no historical drilling or systematic exploration, a surprising fact given the Yandal Belt’s rich gold endowment and extensive past activity. Gateway’s geophysical work suggests these zones are structurally complex and highly prospective, with initial surface geochemical sampling programs already underway to refine targets.
Exploration Programs and Upcoming Drilling
Gateway has mobilised teams to conduct rock chip, soil, and lag sampling, alongside detailed mapping. Spectral and multi-element analyses of historic drill chips are nearing completion, enhancing geological models. A 3D Induced Polarisation survey is in progress at the Dusk ‘til Dawn prospect, designed to sharpen drill targeting. The company aims to commence a substantial aircore drilling program in October, followed by targeted diamond drilling at Dusk ‘til Dawn in November, leveraging co-funded drilling approvals.
Financial Position and Market Context
Gateway remains well capitalised with approximately $12.1 million in cash and liquid ASX-listed securities, providing a solid financial foundation for its aggressive exploration agenda through 2025 and 2026. The proximity of the Yandal Project to Northern Star’s Jundee operations adds strategic value, positioning Gateway to potentially unlock significant new gold resources in a globally recognised mining district.
Outlook and Potential Impact
This discovery of extensive, underexplored shear zones could redefine the geological understanding of the Yandal Gold Project and materially enhance Gateway’s resource base. While assay results from ongoing sampling are pending, the combination of modern geophysical techniques and planned drilling campaigns sets a promising stage for new discoveries. Investors and analysts will be watching closely as Gateway progresses its exploration milestones.
Bottom Line?
Gateway Mining’s identification of vast new shear zones at Yandal marks a pivotal exploration phase that could reshape its growth trajectory.
Questions in the middle?
- What assay results will the initial surface sampling programs reveal about gold mineralisation?
- How will the upcoming aircore and diamond drilling campaigns refine the resource potential?
- Could Gateway’s new structural model lead to a significant resource upgrade in the Yandal Belt?
