Unity Metals Extends O’Phlay Gold Mineralisation to 230m with 70m Intercept

Unity Metals has significantly expanded the known gold mineralisation at its O’Phlay Gold Project in Cambodia, hitting a 70.4m intercept at 1.1 g/t gold that extends the deposit to at least 230m depth and remains open.

  • 70.4m at 1.1 g/t gold intercept extends mineralisation depth
  • Broad gold zone confirmed steeply dipping and open at depth
  • Further 20 holes planned to test extensions and new targets
  • Mineralisation linked to intrusion-related gold system
  • Drilling paused for monsoon, to resume in October

Significant Deep Gold Intercept Expands O’Phlay Prospect

Unity Metals Limited (ASX:UM1) has delivered a substantial boost to its O’Phlay Gold Project in Cambodia, reporting a standout drill intersection of 70.4 metres at 1.1 grams per tonne (g/t) gold from 195 metres depth in hole 26DDCM005. This intercept extends the known mineralised zone to at least 230 metres below surface, confirming the continuity of a broad, gold-bearing quartz-arsenopyrite vein system hosted within diorite.

The mineralisation, which was initially discovered in hole 26DDCM001 with 40m at 1.9 g/t gold, is now demonstrated to be steeply dipping to the southeast with a true width estimated between 45 and 50 metres. Crucially, the zone remains open at depth, offering promising potential for further resource expansion.

Geological Context and Structural Controls

The gold-bearing veins align with a prominent northeast-trending magnetic high anomaly that extends for kilometres within the O’Phlay licence area. This structural orientation is supported by vein measurements in drill core and surface exposures in historical mine workings, suggesting a coherent mineralised system striking northeast and dipping steeply southeast. The intrusion-related gold (IRG) style mineralisation is comparable to Unity’s Ngot Gold Project and Emerald Resources’ Okvau Gold Mine, located some 60 kilometres to the west.

While holes 26DDCM002 to 004 returned no significant gold, their positioning relative to the interpreted mineralised trend explains the lack of intercepts, with 26DDCM003 notably drilled too far west of the main zone. Hole 26DDCM007, drilled 20 metres north of the discovery hole, intersected a broad stockwork vein zone approximately 40 metres wide, with assays pending. Conversely, 26DDCM006 intersected only narrow mineralised intervals, hinting at a possible narrowing of the mineralised corridor to the southwest.

Expanding the Drill Program and Targeting Historical Mines

Building on these encouraging results, Unity plans a further 20 diamond drill holes (approximately 3,250 metres) at O’Phlay. The upcoming campaign will focus on delineating lateral and depth extensions to the Camp Prospect mineralisation, as well as testing six new targets including the largest historical open pits located 0.8 kilometres northwest and underground workings at the Small Creek Prospect 1.8 kilometres south.

Historical mining at Small Creek focused on high-grade arsenopyrite-rich veins, with Unity’s recent rock chip sampling returning assays up to 37.1 g/t gold. The company aims to test these veins and surrounding stockwork mineralisation with modern drilling for the first time, potentially unlocking significant new resources.

Operational Pause and Next Steps

Drilling at O’Phlay is currently paused for about a month due to the peak monsoon season, with the man-portable diamond rig demobilised for maintenance. Operations are expected to resume in October 2026, with assay results from ongoing holes anticipated during the December quarter.

Unity’s Managing Director Craig Mackay emphasised the significance of the intercepts, stating that the broad mineralisation remains open and that the company has abundant exploration opportunities across multiple targets marked by extensive magnetic anomalies. The confirmation of a large, continuous IRG system at O’Phlay marks a key milestone in Unity’s Cambodian exploration campaign.

Bottom Line?

Unity Metals’ deep, broad gold intercept at O’Phlay underpins a compelling exploration upside, with a sizeable drilling program set to test extensions and historical mining zones after the monsoon break.

Questions in the middle?

  • Will pending assays from holes 26DDCM006 and 26DDCM007 confirm lateral continuity or narrowing of mineralisation?
  • Can drilling beneath the largest historical open pits and underground workings reveal new high-grade zones?
  • How will the monsoon-related pause affect the timing and momentum of Unity’s exploration campaign?
