Angkor Resources Corp. reported results from diamond drill hole AB25-009 completed at the Thmei North copper target on the Andong Bor mineral exploration license in Cambodia. The drill hole returned copper mineralization over the entire 286.2 metres sampled, with grades increasing significantly at depth.
Diamond drill hole AB25-009 was completed on July 18, 2025, to a depth of 312.2 metres. The hole was drilled near vertical and sampled continuously over 286.2 metres, returning an overall average of 1,309 parts per million (ppm) copper (0.13% Cu). Notably, copper grades increased with depth.
The bottom 67.3 metres of the hole averaged 2,181 ppm copper (0.22% Cu), including a 52.6-metre interval grading 2,493 ppm copper (0.25% Cu). The hole ended in mineralization, suggesting the copper-bearing system continues at depth. The upper portion of the hole cored a medium-grained diorite ?
a dense, granite-like rock ? to a depth of 244.9 metres. Throughout this section, the drill core contained small quartz veins carrying iron and copper minerals.
At 244.9 metres, the hole crossed into hornfels, which are older sedimentary rocks that have been hardened by heat from the nearby diorite intrusion. Within the hornfels, the number of mineral-bearing veins increased significantly, and copper content rose accordingly. 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 and personnel remains the Company?s top priority, and activities on the Andong Bor license are on hold until conditions allow safe resumption. Thmei North is located on relatively flat farmland and is defined by an approximately one-square-kilometre copper soil anomaly. An earlier target, Thmei South, is located roughly three kilometres to the south and was the site of a historical diamond drill hole (ABDDH16-006) completed in 2016.
That hole cored diorite for the upper 135 metres, with the remaining 127 metres described as hornfels containing a stockwork of veins with copper and other sulphide minerals. The lower portion of this historical hole was never sampled. The Company will assist year-five students at the Cambodian Institute of Technology in a study of ABDDH16-006, providing additional data on the copper potential of the Thmei area and advancing the degrees of Cambodia?s future geologists.
