Yandal Resources Uncovers Multiple Parallel Gold Zones Beneath Flushing Meadows Deposit in WA

Yandal's Diamond Drilling at Flushing Meadows Reveals Fresh Rock Mineralisation Below Current Resource Boundary

Beginning in late April 2026, Yandal Resources initiated a diamond drilling program at Flushing Meadows targeting primary fresh rock mineralisation roughly 100m beneath the fresh rock boundary. This program aims to systematically test primary mineralisation, evaluate high-grade potential within fresh rock, and identify key geological controls. To date, eight diamond holes spaced 200m apart have covered 1.6 kilometres of strike across the deposit.

Results from diamond hole 26IWBRC0098DA, the second of eight planned holes, reveal significant gold intercepts confirming mineralisation in fresh rock below the current Mineral Resource Estimate. The mineralisation occurs within heavily deformed and altered sedimentary units, consistent with earlier findings.

Noteworthy Gold Intercepts from Diamond Core and RC Pre-collar in Hole 26IWBRC0098DA

Diamond core assays from hole 26IWBRC0098DA returned multiple significant intercepts, including 4.8m at 2.3g/t Au from 175.2m depth (true width 4.5m), featuring a high-grade 1m interval at 6.5g/t Au from 178m. Additional intercepts include 2m at 2.9g/t Au from 188m and 2.2m at 1.2g/t Au from 225.2m, plus a smaller 0.2m intercept at 3.1g/t Au from 144.3m.

The RC pre-collar above the diamond core returned encouraging results, including 20m at 1.7g/t Au from 55m (true width 18m), with 1m at 3.5g/t Au at 55m and 9m at 2.7g/t Au from 64m. Another intercept of 5m at 0.8g/t Au from 113m (true width 4m) included 1m at 3.0g/t Au from 115m. Collectively, these results demonstrate mineralisation continuity and multiple mineralised zones.

Discovery of Multiple Parallel Mineralised Structures in Hanging Wall

Hole 26IWBRC0098DA provides strong evidence of multiple sub-parallel mineralised zones in the hanging wall, located above and east of the current Flushing Meadows Mineral Resource Estimate. These zones remain open at depth and along strike, offering significant exploration upside. These newly identified parallel structures differ from the main mineralised system currently defined over a 1.9-kilometre strike.

Managing Director Chris Oorschot stated the results clearly indicate that the existing Mineral Resource Estimate captures only a small segment of the broader mineralised system. The company’s geological interpretation supports a systematic approach to expanding the deposit, with multiple parallel structures suggesting substantial potential for resource growth both at depth and along strike.

Follow-up RC Drilling to Test Newly Identified Hanging-Wall Mineralisation

Yandal Resources has completed four follow-up RC drill holes adjacent to diamond holes 26IWBRC0098DA and 26IWBRC0099D to assess the lateral continuity and grade of the newly discovered parallel hanging-wall mineralised structures. These RC holes form the initial phase of extensional drilling aimed at validating the presence of multiple mineralised zones.

Results from the remaining six diamond holes and four follow-up RC holes are expected in August 2026. These will be critical for defining the extent of hanging-wall mineralisation and evaluating its potential to significantly increase the Flushing Meadows resource. The combined diamond and RC drilling will support geological modelling and guide future resource expansion.

Extensive Air-Core Drilling Across Flushing Meadows and Giedi Prime Targets

Alongside diamond drilling, Yandal Resources is conducting a large-scale air-core drilling program across Flushing Meadows and the Giedi Prime target areas. Approximately 8,000 metres have been drilled over 89 holes spaced 800 metres apart. This program aims to delineate the Flushing Meadows mineralised system's scale and assess Giedi Prime’s potential for hosting significant mineralisation.

Managing Director Oorschot noted that Giedi Prime shares structural similarities with Arrakis and Flushing Meadows, making it a promising exploration target. Ongoing air-core results will help prioritize future drilling and refine the exploration strategy across the Ironstone Well-Barwidgee Gold Project.

Arrakis RC Drilling Highlights Scytale Shear Zone as Mineralisation Boundary

At the Arrakis prospect, nine RC holes tested for southeast extensions beyond the north-south striking Scytale Shear Zone. Results showed only low-level gold anomalism (0.1–0.3g/t Au) within targeted stratigraphy, indicating the shear zone acts as a hard boundary for primary mineralisation in that direction.

Despite the lack of economic mineralisation southeast of the shear zone, higher-grade mineralisation adjacent to the Scytale Shear Zone suggests it plays a key role in localising gold. Additionally, six RC holes have been completed at the Anders prospect, about 900 metres south of Arrakis, targeting a parallel regolith anomaly near the shear zone projection, potentially validating the structural control concept.

Geological Model and Exploration Strategy Development at Ironstone Well-Barwidgee

Exploration results from Flushing Meadows and Arrakis are shaping the geological model for the Ironstone Well-Barwidgee Gold Project. Key insights include sediments as the primary host for fresh rock gold mineralisation, multiple sub-parallel mineralised zones in the hanging wall, and the importance of shear zones in controlling mineralisation distribution and grade. These findings refine Yandal Resources’ exploration targeting and drilling strategies.

Managing Director Oorschot emphasized that the company’s systematic, geology-driven approach is yielding results by identifying new mineralised zones and expanding understanding of the Flushing Meadows system. The staged drilling programs—diamond, air-core, and follow-up RC—are building confidence in the deposit’s scale and potential for additional mineralisation.

Flushing Meadows Mineral Resource Estimate and Expansion Potential

The current Flushing Meadows Mineral Resource Estimate covers a 1.9-kilometre strike and contains 268,000 ounces of gold. However, recent diamond drilling indicates this estimate captures only a fraction of the total mineralised system. Identification of multiple parallel mineralised structures in the hanging wall and mineralisation continuity in fresh rock below the resource suggest significant expansion potential.

Drilling with 200-metre diamond hole spacing and 800-metre air-core lines is expected to provide sufficient data for an expanded resource estimate. Results from the remaining diamond and RC holes, due in August, will be pivotal in quantifying additional mineralisation and guiding future development and drilling plans at Flushing Meadows.

Project Location and Operational Overview in Western Australia Gold Exploration

Yandal Resources is advancing exploration at the Ironstone Well-Barwidgee Gold Project, located in one of Australia’s premier gold regions in Western Australia. The company is headquartered in West Perth, with its registered office at Suite 1, Level 3, 1138 Hay Street. The project hosts multiple prospects including Flushing Meadows, Arrakis, Giedi Prime, and Anders, indicating a large mineralised system with numerous targets. Leadership includes Managing Director Chris Oorschot, Non-Executive Chairman Greg Evans, and Non-Executive Directors Katina Law and Chris Newman, providing operational and strategic guidance.

The timing and systematic nature of the exploration programs demonstrate Yandal Resources’ active phase of resource definition and discovery. Their focus on primary fresh rock mineralisation at depth, complemented by broad surface air-core drilling, reflects a strategy to expand current deposits and uncover new mineralisation. Regular updates underscore the company’s commitment to transparent communication and disciplined exploration.
