Angkor Resources Corp. has reported copper mineralization over the entire 286.2 metres sampled in diamond drill hole AB25-009 at the Thmei North copper target on the Andong Bor mineral exploration license in Cambodia. The drill hole, completed on July 18, 2025, returned an overall average of 1,309 parts per million copper, with grades increasing significantly at depth. The bottom 67.3 metres of the hole averaged 2,181 ppm copper, including a 52.6-metre interval grading 2,493 ppm copper. The hole ended in mineralization, suggesting the copper-bearing system continues at depth.
The upper portion cored a medium-grained diorite to 244.9 metres, containing small quartz veins with iron and copper minerals, before crossing into hornfels where mineral-bearing veins increased significantly along with copper content. Dennis Ouellette, VP Exploration, stated that the increase in copper grade deeper into the hornfels is encouraging. He explained that the contact between the diorite and hornfels is very steep, with mineralized quartz veins following these same structures. The hornfels hosts more veins and higher copper grades, and copper mineralization within the diorite itself indicates good potential in both rock types.
Ouellette added that these results reinforce the view that strongest mineralization is concentrated near or within the hornfels surrounding diorite intrusions. He described the deposit as a hybrid porphyry copper-related skarn, where small bodies of diorite and feldspar porphyry dikes have intruded into highly receptive siltstone and volcaniclastic rocks. The hornfels shows potassic alteration, a strong indicator of being in the right area, with early potassic alteration overprinted by later chlorite-sericite and phyllic alteration typical of copper porphyry systems.
A second drill hole, AB25-010, was started on July 20, 2025, but was halted due to the Cambodia-Thailand border conflict in the northwest region. Safety of staff remains the company's top priority, and activities on the Andong Bor license are on hold until conditions allow safe resumption. The company will assist year-five students at the Cambodian Institute of Technology in studying historical drill hole ABDDH16-006 from Thmei South, providing additional data on copper potential and advancing the education of Cambodia's future geologists.
