Unity Metals Uncovers New Gold Zones Across Cambodia With Drilling Set to Follow
Key Takeaways
- The headline trench result of 22m @ 0.9 g/t gold including 2m @ 7.7 g/t gold at Ngot Central confirms surface continuity of mineralisation in an area where high-grade drill intercepts were projected to outcrop.
- Trenching at Ngot NE revealed that Unity's initial drilling was oriented sub-parallel to the gold-bearing veins — a fundamental geometry error — meaning the target has never been properly tested and re-oriented drilling is now required.
- A 700m coincident gold and arsenic soil anomaly sits along a NNE-trending structural corridor that extends 2.2km to the Okvau Gold Mine, a 1.5Moz deposit operated by Emerald Resources.
- The Phase 2 20-hole diamond drill program at O'Phlay remains on schedule for October commencement, with assays from holes 26DDCM006 and 26DDCM007 expected in late September — providing near-term catalysts before year-end.
- Demagnetised zone targets at O'Phlay — associated with previously announced intercepts of 40m @ 1.9 g/t gold and 70.4m @ 1.1 g/t gold — remain entirely untested by this trench program and represent a separate, undrilled opportunity.
Trenching exposes new gold zones across Unity Metals’ Cambodian projects
A completed 9-trench program is adding meaningful detail to Unity Metals’ Cambodian gold exploration story. The ASX: UM1 company holds a ~700km² portfolio in Cambodia, situated near the Okvau Gold Mine, a 1.5Moz deposit operated by Emerald Resources, and has now completed 1,063m of trenching across the Ngot and O’Phlay Gold Projects.
The headline result from the program is 22m @ 0.9 g/t gold including 2m @ 7.7 g/t gold from Trench 26TRNC001 at Ngot Central. Crucially, new zones of gold mineralisation have been identified outside the areas of existing drilling across multiple prospects, with drill follow-up now required at several locations.

Key results from Ngot and O’Phlay trenching
Ngot Project highlights
Three prospects at the Ngot Project returned meaningful gold intersections from the trenching program.
Ngot Central (Trench 26TRNC001) delivered multiple anomalous zones:
- 18m @ 0.5 g/t gold from 4m, including 2m @ 2.6 g/t gold from 8m
- 6m @ 3.0 g/t gold from 52m, including 4m @ 4.4 g/t gold from 52m
- 22m @ 0.9 g/t gold from 142m, including 2m @ 7.7 g/t gold from 146m
- 8m @ 0.4 g/t gold from 174m
The broad zone from 142m confirms continuity of mineralisation to surface in an area where high-grade veins intersected in drilling are projected to outcrop. Trench 26TRNC001 also located a new mineralised zone with 18m @ 0.5 g/t gold from 4m (including 6m @ 1.2 g/t gold from 50m) to the east of existing drilling coverage, which will require drilling follow-up.
Srolao Prospect (Trench 26TRSL001): 6m @ 1.2 g/t gold from 41m, including 1m @ 6.1 g/t gold from 46m. This result confirms the interpreted NNE-trending orientation of the gold mineralisation, with a width and grade similar to an adjacent drill hole intersection.
Ngot NE (Trench 26TRNE001): grab rock chip samples from mineralised quartz veins returned up to 7.8 g/t gold. The trench exposed mineralisation running parallel to the trench direction, making channel sampling inappropriate, so individual grab samples were taken instead.
A tenth trench at the Rohav Mountain Prospect (26TRRM001, 89m cleared) uncovered a historical artisanal excavation across a zone of stockwork quartz veining. Geological mapping has been completed, but sampling is pending and no assay results are yet available from this location.
O’Phlay Project — Camp Prospect
Five trenches (26TRCM001 through 26TRCM005), totalling 583m, were completed at the Camp Prospect, designed to test conductivity anomalies identified in Gradient Array Induced Polarisation (GAIP) data. GAIP is a geophysical technique that measures how the ground responds to electrical currents, helping identify zones that may host sulphide minerals associated with gold.
The best intersection was 20m @ 0.2 g/t gold from 46m including 1m @ 2.6 g/t gold from 51m (Trench 26TRCM002), a width that the company notes will require drilling follow-up. Trench 26TRCM005 returned a rock chip assay of 1.9 g/t gold from an arsenopyrite-mineralised quartz vein in an area of historical artisanal workings.
An important piece of context: this trench program was designed before Unity received magnetic data revealing that the recently discovered stockwork gold system (previously announced intersections of 40m @ 1.9 g/t gold and 70.4m @ 1.1 g/t gold) trends NE-NNE and is closely associated with a demagnetised zone. As a result, no trenches were designed to test the demagnetised zone targets. Those targets remain untested by this program.
Summary of key trench results:
| Prospect | Trench ID | Best Intersection | Rock Chip High | Follow-up Required? |
|---|---|---|---|---|
| Ngot Central | 26TRNC001 | 22m @ 0.9 g/t Au from 142m incl. 2m @ 7.7 g/t Au | — | Yes |
| Srolao | 26TRSL001 | 6m @ 1.2 g/t Au from 41m incl. 1m @ 6.1 g/t Au | — | Yes |
| Ngot NE | 26TRNE001 | — | 7.8 g/t Au | Yes — re-oriented drilling required |
| Rohav Mountain | 26TRRM001 | Sampling pending | — | Pending sampling results |
| Camp (O’Phlay) | 26TRCM002 | 20m @ 0.2 g/t Au from 46m incl. 1m @ 2.6 g/t Au | — | Yes — drill follow-up required |
| Camp (O’Phlay) | 26TRCM005 | — | 1.9 g/t Au | Yes |
Why the Ngot NE breakthrough matters
The most structurally significant outcome from this program may not be the best grade result, but what Unity learned about its own drilling at Ngot NE.
The trenching confirmed that Unity’s initial drilling at Ngot NE was orientated sub-parallel to the gold mineralisation. In plain language: the drill holes were largely running alongside the gold-bearing veins rather than cutting through them at an angle. Think of it like trying to measure the thickness of a wall by walking along it rather than stepping through it. You will pass through very little of what you are trying to measure. Re-oriented drilling, angled to cut across the structures properly, is needed to genuinely test the target.
The structural picture that has emerged is significant. Unity’s interpretation is that there is an overall NNE-trending structural corridor that extends to the Okvau Gold Mine 2.2km to the north, with a 700m long coincident gold and arsenic soil anomaly lying along the structural corridor. Within this corridor, subordinate east-west structures host gold mineralisation in steeply dipping arsenopyrite-rich quartz veins. The correction of the drilling orientation represents a genuine step-change in how this target will be tested, though it should be noted that no resource or discovery has been defined — this is a refined exploration vector.
Exploration Manager Shane Hibbird drew a direct comparison to Okvau’s early-stage history:
Shane Hibbird, Exploration Manager
“Back in 2012 – 2013, during my time as Exploration Manager in Cambodia at Okvau for Renaissance Minerals we regarded any broad intervals >0.1 g/t gold in shallow trenching in the upper saprolite as significant and worthy of further investigation. Any narrow intervals of higher grade also gave encouragement for additional work. The results we have received in the Unity trenching at Ngot and O’Phlay are on par with those we chased-up with drilling at Okvau.”

What’s next — October drilling and near-term catalysts
The near-term newsflow calendar for Unity is reasonably well defined. The Phase 2 20-hole diamond drill program at O’Phlay remains on schedule for commencement in October.
The key catalyst sequence is:
- Late September: Assays expected for diamond drill holes 26DDCM006 and 26DDCM007 at the Camp Prospect, O’Phlay
- Early October: Phase 2 drilling commences at O’Phlay
- Future program: Re-oriented drilling at Ngot NE to properly test the structural corridor trending toward Okvau
Beyond Cambodia, Unity also holds licence applications for copper-gold assets in Thailand in the Loei Fold Belt, providing additional portfolio breadth. For now, though, the Cambodian projects are the near-term focus, with multiple assay results and a fresh drill program set to drive the next phase of newsflow before the end of the year.
