Unity Metals Achieves Record Gold Intersection in Cambodia with 40m at 1.9 g/t at O'Phlay Camp Prospect

First Modern Drilling at O'Phlay Confirms Intrusion-Related Gold Mineralisation

Unity Metals has finalized its first modern drilling campaign at the O'Phlay Gold Project in Mondulkiri Province, eastern Cambodia, achieving what it describes as its best gold result in the country to date. The initial drill hole, 26DDCM001, targeted a broad zone of diorite-hosted, gold-bearing veins exposed in historical open pits at the Camp Prospect, alongside a coincident Gradient Array Induced Polarisation (GAIP) chargeability anomaly identified in recent geophysical surveys. Despite clear signs of past mining, no modern drilling had been conducted previously at O'Phlay.

The mineralisation style at O'Phlay is classified as intrusion-related gold (IRG), comparable to Unity's Ngot Gold Project and the Okvau Gold Mine operated by Emerald Resources roughly 60 kilometres west. This geological similarity validates the exploration model and regional prospectivity. Historical mining at Camp Prospect indicates prior recognition of mineralisation, but the absence of modern drilling data left significant exploration upside. Unity’s current program aims to systematically quantify and extend known mineralisation using contemporary techniques.

Geological Setting and Mineralisation Characteristics at Camp Prospect

The gold mineralisation intersected in hole 26DDCM001 occurs within diorite and is associated with both massive and stockwork quartz-arsenopyrite veins. Massive quartz-arsenopyrite veins reach up to 20 metres wide, with adjacent stockwork veins forming a broader mineralised halo. This vein-stockwork association is typical of intrusion-related gold systems, indicating a potentially large target. Mineralisation extends from surface through the drill hole and remains open at depth and along strike, suggesting significant potential extensions.

Geophysical surveys identified two major GAIP chargeability anomalies in the eastern Camp Prospect, extending over 1.8 kilometres. These anomalies are interpreted as indicators of additional mineralisation and represent a large area for systematic follow-up drilling. The correlation between surface stockwork mineralisation, GAIP anomalies, historical mining, and gold-in-soil anomalies supports the interpretation that Camp Prospect hosts a substantial intrusion-related gold system with multiple drill targets.

Camp Prospect Drilling Program and Initial Results from Hole 26DDCM001

To date, Unity has completed four diamond drill holes (26DDCM001–004) at Camp Prospect, totaling 570.6 metres. Assays have been received only for the first hole, 26DDCM001, which revealed two significant gold intervals. The primary intersection is 40 metres at 1.9 g/t gold from 82 metres depth, including a higher-grade 17 metres at 3.9 g/t gold from 82 metres. Within this zone is a 5-metre interval at 10.5 g/t gold from 85 metres, the highest-grade intercept in the hole. A secondary interval of 8.5 metres at 0.7 g/t gold was recorded from 129.5 metres depth.

These results confirm continuous mineralised diorite with variable gold grades over a substantial vertical interval. The nested assay pattern—higher-grade zones within broader lower-grade envelopes—is consistent with vein-hosted mineralisation where quartz veins and alteration halos create wider gold-bearing zones. Mineralisation remains open at depth and along strike, indicating potential for significant expansion. Assays for holes 26DDCM002–004 are pending and expected to further define mineralisation style and distribution.

Expansion of Drilling Program to Pursue High-Grade Zones

Encouraged by the results from hole 26DDCM001, Unity has opted to extend its drilling program beyond the original 3,000-metre, 21-hole plan. This expansion reflects management’s confidence in the geological model and the significance of the initial intercept. Additional holes will test mineralisation extensions at depth beneath Camp Prospect and along strike from the current intersection.

Drill locations are selected based on recent geophysical surveys, geological mapping, and geochemical sampling. Unity’s strategy is to systematically test the two prominent 1.8-kilometre GAIP chargeability anomalies in the eastern Camp Prospect. This approach aims to delineate mineralisation geometry and grade distribution and identify further high-grade zones. Additional assay results expected soon will guide further drill targeting and exploration priorities.

Unity Metals' Regional Portfolio and Strategic Position in Cambodia

Unity Metals Limited is an ASX-listed gold and copper explorer with a significant portfolio in Southeast Asia, focusing on Cambodia and Thailand. Its projects target intrusion-related gold and porphyry copper-gold deposits. In Cambodia, Unity’s assets are strategically located near two operating gold mines, including the Okvau Gold Mine—the country’s largest—with a 1.5 million ounce resource. Notably, Unity’s Ngot Gold Project shares a boundary with the Okvau licence, positioning it adjacent to a producing asset.

This proximity offers exploration advantages, demonstrating the region’s economic gold potential and validating Unity’s exploration concepts. The company’s total landholding spans approximately 700 square kilometres across Cambodia and Thailand, providing multiple discovery and development opportunities. The O'Phlay Gold Project benefits from its location near a historical Vietnamese processing plant and visible past mining activity, supporting the presence of mineable-grade mineralisation.

Comparison with Other Unity Projects and Market Position

Unity’s managing director, Craig Mackay, stated that the 40-metre intersection at 1.9 g/t gold from O'Phlay is "by far the best" gold result achieved by Unity in Cambodia to date. This highlights O'Phlay’s emerging importance within the company’s portfolio. While recent gold discoveries at Ngot are promising, the O'Phlay result suggests it may become a priority asset. The decision to accelerate and expand drilling at O'Phlay reflects a strategic shift towards the most prospective projects.

The similarity in mineralisation styles between O'Phlay and Ngot—both intrusion-related gold systems akin to the producing Okvau mine—validates Unity’s exploration models and technical approach. The immediate program expansion signals management’s confidence in O'Phlay’s discovery potential. In a competitive Southeast Asian exploration environment, the ability to quickly identify and build on significant intersections is a key advantage, and Unity’s increased drilling commitment demonstrates dedication to advancing exploration success.

Historical Mining and Exploration Potential at O'Phlay

O'Phlay’s history of mining activity provides both validation and exploration upside for Unity Metals. The area shows evidence of extensive historical open-pit and underground gold mining, indicating prior economic extraction. A historical Vietnamese processing plant adjacent to Camp Prospect further confirms past production. However, no modern diamond drilling had been conducted before Unity’s current program, suggesting substantial unexplored potential remains.

Historical mining typically targeted the richest, most accessible ore. Modern drilling and exploration may reveal broader, lower-grade mineralisation zones that could be economically viable with current mining and processing technologies. Gold-bearing veins exposed in historical open pit walls remain largely untested at depth. Unity’s drilling program systematically evaluates these opportunities. The absence of modern exploration data at a historically mined site suggests early-stage discovery potential remains, supporting the decision to expand drilling.

Geophysical Targeting and Upcoming Drill Strategy

Unity’s recent Gradient Array Induced Polarisation (GAIP) geophysical survey identified two prominent chargeability anomalies over 1.8 kilometres in eastern Camp Prospect. These anomalies align spatially with surface gold-bearing veins and gold-in-soil anomalies. GAIP detects induced polarisation responses linked to disseminated sulphides and is widely used in gold exploration to locate mineralisation beneath surface cover. The strong, consistent geophysical responses at Camp Prospect bolster confidence in the geological model and justify systematic drilling along these anomalies.

The planned approach involves drilling a grid of holes to define mineralisation geometry and continuity. This geophysically guided strategy is more efficient than random drilling and increases the likelihood of significant intercepts. The first hole, 26DDCM001, was drilled beneath surface mineralisation and a coincident geophysical anomaly, validating this targeting method. As assays from holes 26DDCM002–004 arrive, drill targets will be refined to prioritize the most promising zones and test mineralisation continuity hypotheses.

Investor Outlook and Upcoming Milestones

Investors should monitor assay releases from holes 26DDCM002–004 expected in the coming weeks. These results will clarify mineralisation consistency and extent across Camp Prospect and may influence the expanded drilling program design. The high-grade 5-metre interval at 10.5 g/t gold suggests potential for significant grades, though further data is needed to determine if this zone is consistent or isolated. Confirmation in adjacent holes would strengthen the case for a larger continuous mineralised system.

The decision to extend drilling is a strong indicator of management’s positive assessment of O'Phlay’s discovery potential. Additional capital will be needed to fund the expanded drilling and technical work. The project’s proximity to the producing Okvau mine and regional infrastructure may support future development if exploration confirms economic mineralisation. The timing of drilling results and management guidance on resource estimation or exploration strategy will be critical for investors evaluating Unity’s near-term momentum and long-term value creation.
