Unity Metals Discovers Broad Stacked Gold Zones at Rohav Mountain in Cambodia

Mining By Maxwell Dee 4 min read

Unity Metals reveals broad stacked gold zones beneath cover at Rohav Mountain and high-grade veins at Ngot Central, reinforcing potential for intrusion-related gold deposits near Cambodia's Okvau Mine.

  • Stacked gold mineralisation discovered in wide diorite intrusion at Rohav Mountain
  • High-grade veins at Ngot Central show strong continuity over 200m down-dip
  • Drilling program nearly 90% complete with assays pending for key prospects
  • Mineralisation style akin to nearby Okvau Mine’s intrusion-related gold system
  • Additional prospects Srolao and Ngot NE being actively drilled with results awaited

Broad Gold Zones Uncovered Under Cover at Rohav Mountain

Unity Metals (ASX:UM1) has struck stacked zones of shallow-dipping gold mineralisation hosted within a substantial, highly altered diorite intrusion at its Rohav Mountain Prospect in Cambodia. This discovery is notable for occurring beneath soil and basalt cover, where surface geochemical guidance was limited, making the initial drill success particularly encouraging. The diorite intrusion measures over 150 metres wide and is interpreted to extend at least 700 metres in length, though its full extent remains undefined.

Key drill results from Rohav Mountain include a 23-metre intercept grading 0.9 g/t gold from 120 metres depth, including a higher-grade 6 metres at 1.9 g/t gold, alongside a 1-metre intercept at 7.9 g/t gold from 33 metres. These findings highlight the presence of multiple generations of quartz-pyrite-arsenopyrite veins with epithermal-style sulphide assemblages, underpinning the mineralisation.

High-Grade Veins at Ngot Central Confirm Continuity

At the Ngot Central Prospect, Unity Metals has reported additional high-grade gold intersections within stacked quartz-pyrite-arsenopyrite veins hosted by a 1.5 km by 1 km diorite intrusion. Noteworthy assays include 0.4 metres at 32.8 g/t gold and 0.7 metres at 14.3 g/t gold, both from shallow depths. Importantly, this high-grade vein has been traced continuously for more than 200 metres down-dip, suggesting robust structural control and potential for resource expansion.

The mineralisation style at Ngot Central closely resembles the intrusion-related gold (IRG) system typified by the nearby Okvau Mine, located just 2 km north. This proximity and geological similarity add weight to the exploration potential of Unity’s licence areas. The company’s ongoing drilling program, now nearly 90% complete, is focused on defining these zones further, with assays received for approximately 40% of the planned 50 holes.

These latest results build on earlier promising findings, forming part of a steady stream of assay releases that continue to shape the project’s outlook. This progress follows Unity Metals’ earlier high-grade gold intersections reported in March, which first highlighted the Ngot Project’s resemblance to Okvau’s mineralisation style.

Exploration Momentum at Srolao and Ngot NE Prospects

Beyond Rohav Mountain and Ngot Central, Unity Metals is advancing drilling at the Srolao and Ngot NE prospects. Srolao features some of the thickest gold-bearing veins encountered so far, with rock chip assays up to 27.4 g/t gold and extensive soil anomalies exceeding 5,900 ppb gold. Drilling at Srolao has identified narrow mineralised zones, though assays remain pending.

Ngot NE, the closest prospect to the Okvau Mine, is defined by a strong gold-in-soil anomaly coupled with the largest arsenic-in-soil anomaly in the project area, a geochemical signature often associated with intrusion-related gold systems. Initial drilling has encountered arsenopyrite-rich veins with mineralised intervals up to 3 metres wide, with further holes underway and assay results awaited.

Environmental and Regulatory Considerations

Unity’s licences lie partly within environmentally protected areas in Cambodia, requiring government approvals for exploration and mining activities. The company has secured exploration approvals following environmental assessments and notes that mining approvals would necessitate further detailed studies. This regulatory backdrop parallels that of the Okvau Mine, which also operates within a protected area with appropriate government permissions.

Exploration manager Shane Hibbird, a Competent Person under the JORC Code, has overseen the drilling and sampling, which adhere to industry best practices and quality control protocols. While true widths of mineralisation are yet to be determined, the reported downhole intercepts provide a solid foundation for ongoing resource evaluation.

Bottom Line?

Unity Metals’ expanding footprint of stacked gold mineralisation under cover and high-grade veins near a major Cambodian mine signals promising exploration upside, but much depends on pending assays and further drilling to delineate resource potential.

Questions in the middle?

  • How will upcoming assay results from Rohav Mountain and Ngot NE influence resource modelling?
  • Can Unity Metals delineate a coherent resource with economic grades given the current drill spacing?
  • What are the implications of operating within protected environmental areas for project development timelines?
