Angkor Resources Corp. has advanced its analysis of drill core from the Andong Bor license in Oddar Meanchey, Cambodia, revealing significant geological insights that could impact future exploration strategies. The company's VP Exploration Dennis Ouellette and associate geologists reviewed both historical drilling data and newly drilled holes from 2025, identifying mineralization with abundant pyrite and chalcopyrite in sections from 245 metres to 316 metres depth.
The 2025 drill core from holes ABDDH25-009 and -010 is currently being logged in detail and cut for sampling purposes, with assays to be forwarded to ALS laboratory when cutting is complete. This represents a substantial advancement from previous analysis conducted in late 2022, which was based solely on core drilled by a different company as detailed in the press release https://angkorresources.com/angkor-confirms-108-metres-of-0-53-copper-equivalent-at-andong-bor-cambodia/.
Ouellette summarized the critical findings, noting that "the best copper mineralization in Andong Bor diamond drill core is hosted by the sedimentary rocks." While diorite feldspar porphyry intrusive rocks contain low-grade copper porphyry-style mineralization, assay values increase dramatically in proximity to highly reactive wallrock where intrusive rock meets sedimentary formations.
The analysis revealed that contacts between sedimentary and intrusive rock are exceptionally steep, ranging from 70 to 80 degrees. Mineralization within the sediments occurs both as disseminated particles and along fractures parallel to these contacts, indicating significant ground preparation likely involving magma or similar catalysts prior to mineralization events. The sedimentary country rock was heavily fractured, allowing intrusion and mineralization to follow pre-existing fracture patterns.
These geological insights have substantial implications for the company's exploration program. Understanding the structural relationships and mineralization patterns enables more targeted drilling strategies that could result in both shallower and increased mineralized intercepts. The discovery that previous drilling failed to reveal the true structural relationship between intrusive and host sedimentary rock due to faulted contacts or poor core recovery highlights the importance of the current analysis.
The company plans to continue its drilling program into 2026, applying these new geological understandings to optimize exploration efficiency. The identification of steep contacts and fracture-controlled mineralization patterns provides a clearer framework for targeting copper resources in the region, potentially accelerating discovery timelines and reducing exploration costs.
For Cambodia's developing mining sector, these findings represent important technical advancements in understanding the country's geological potential. The detailed analysis of mineralization controls and structural relationships contributes valuable data that could influence exploration approaches across similar geological settings in Southeast Asia.
