Angkor Resources Corp. has advanced its analysis of drill core from the Andong Bor license in Oddar Meanchey, Cambodia, revealing critical geological relationships that could significantly impact future exploration efficiency. The company's VP Exploration Dennis Ouellette and associate geologists reviewed both historical drilling and the most recent 2025 drilled holes ABDDH25-009 and ABDDH25-010, with hole 009 reaching substantially greater depths than previous efforts.
The analysis revealed mineralization with abundant pyrite and chalcopyrite in sections from 245 metres to 316 metres in the new drill holes. This represents a substantial advancement from the company's previous analysis in late 2022, which was based solely on core drilled by a different company as detailed in their earlier press release available at https://angkorresources.com/angkor-confirms-108-metres-of-0-53-copper-equivalent-at-andong-bor-cambodia.
Ouellette summarized the critical findings: "The best copper mineralization in Andong Bor diamond drill core is hosted by the sedimentary rocks. The diorite feldspar porphyry intrusive rocks can host low grade copper porphyry-style mineralization, such as 'B' and 'D' style veins and disseminations. However, in proximity to the highly reactive wallrock where the intrusive rock is surrounded by the sedimentary rock, the assay values increase dramatically."
The structural analysis revealed that contacts between sedimentary rock and intrusive rock occur at very steep angles of 70 to 80 degrees. Mineralization within the sediments appears both disseminated and along fractures parallel to these contacts, indicating significant ground preparation prior to mineralization events. The sedimentary country rock was heavily fractured, allowing intrusion and mineralization events to follow pre-existing fracture patterns.
This geological understanding represents a breakthrough for the exploration program. Ouellette emphasized the practical implications: "Knowing this impacts the design of our continuation of the drill program in a manner which we expect will result in both shallower and increased mineralized intercepts." The discovery that mineralization follows pre-existing fractures in sedimentary rocks adjacent to intrusive contacts provides a clear targeting strategy for future drilling.
The 2025 drill core from both holes is currently being logged in detail and cut for sampling purposes, with assays to be forwarded to ALS when all core cutting is completed. Plans for continuation of drilling extend into 2026, with the new geological model expected to optimize drill targeting and potentially reduce exploration costs while increasing discovery rates.
This development is particularly significant for Cambodia's emerging mineral sector, as efficient discovery methods could accelerate the country's development as a mineral producer. The identification of specific geological controls on mineralization represents a substantial advancement in understanding the region's copper potential and could serve as a model for similar exploration targets throughout Southeast Asia.
