Angkor Resources Corp. has reported significant copper mineralization from diamond drilling at its Thmei North prospect on the Andong Bor mineral exploration license in Cambodia. Drill hole AB25-009, completed to a depth of 312.2 metres, returned copper mineralization over the entire 286.2 metres sampled, with an overall average grade of 1,309 parts per million copper. The results show a notable increase in copper content at greater depths, with the bottom 67.3 metres averaging 2,181 ppm copper, including a 52.6-metre interval grading 2,493 ppm copper.
The geological context of this discovery is particularly significant. The upper portion of the hole cored a medium-grained diorite to 244.9 metres, containing small quartz veins with iron and copper minerals. Below this depth, the drill intersected hornfels, where the number of mineral-bearing veins increased substantially alongside higher copper grades. Dennis Ouellette, VP Exploration, stated that the increase in copper grade within the hornfels is encouraging and that mineralization is present in both rock types. He described the deposit as a porphyry copper-related skarn system, where diorite intrusions have interacted with receptive sedimentary rocks.
This discovery carries substantial implications for Cambodia's emerging mineral sector and global copper supply. Copper is a critical metal for electrification and renewable energy infrastructure, and new discoveries are increasingly important as demand grows. The presence of potassic alteration, overprinted by later chlorite-sericite and phyllic alteration, is described as typical of copper porphyry systems, which are known for hosting large, bulk-tonnage deposits. The fact that the hole ended in mineralization suggests the system continues at depth, pointing to further exploration potential.
The project's advancement, however, faces immediate challenges. A second drill hole, AB25-010, was halted due to the Cambodia-Thailand border conflict in the region, with all activities on hold until conditions allow safe resumption. The Thmei North target itself is defined by an approximately one-square-kilometre copper soil anomaly on flat farmland. Historical context adds to the area's prospectivity; a hole drilled at the Thmei South target in 2016 also intersected diorite and hornfels with vein stockworks containing copper and sulphide minerals, though the lower portion was never sampled.
Beyond the immediate drill results, the project has educational significance for Cambodia. The company will assist year-five students at the Cambodian Institute of Technology in a study of the 2016 historical drill hole, providing data on the area's copper potential while helping to train the country's future geologists. For investors and industry observers, detailed information is available through regulatory filings. The technical disclosure in the company's announcement was reviewed and approved by Dennis Ouellette, a Qualified Person as defined by National Instrument 43-101.

The findings at Thmei North represent a meaningful step in understanding Cambodia's mineral endowment. While early-stage, the continuity of mineralization and increasing grades at depth warrant further investigation. Successful development of a copper deposit in Cambodia could contribute to regional economic development and diversify global copper sources. The project's pause due to regional instability also highlights the geopolitical considerations inherent in resource exploration, underscoring that its future depends on both geological success and a return to secure operating conditions.
