Dacian Gold maintains strong governance and internal controls in respect of its estimates of mineral resources and ore reserves and the estimation process.
Dacian ensures its sampling techniques, data collection, data veracity and the application of the collected data is at a high level of industry standard. Contract RC and diamond drilling with QA/QC controls approved by Dacian are used routinely and all completed holes are subject to downhole gyro surveys and collar coordinates surveyed with DGPS. All drill holes are logged by Dacian geologists. Diamond core is oriented and photographed. Dacian employs field QC procedures, including addition of standards, blanks and duplicates ahead of assaying which is undertaken using industry standards including fire assay at Bureau Veritas laboratories in Kalgoorlie.
Assay data is continually validated and stored in DataShed. Geological models and wireframes are built using careful geological documentation and interpretations, all of which are validated by peer review. Resource estimation is undertaken by independent consultants and reported under JORC 2012. Estimation techniques are industry standard and include block modelling using Ordinary Kriging. Application of other parameters including cut off grades, top cuts and classification are all dependent on the style and nature of mineralisation being assessed.
Ore reserve estimation is overseen by in house mining engineers using third party consultants to complete feasibility studies in mining, metallurgical, geotechnical, environmental and social matters. Results are verified by independent third party ore reserve specialist consultancies.
