Saudi Arabia - Phosphates (Field exploration and resource estimation)

Ma’aden contracted Aurum to assist with the exploration and development of a sedimentary phosphate resource in northern Saudi Arabia. In order to produce a resource the following activities were undertaken: • Completion of an RC drill programme, QA/QC oversight, logging of chip samples from both the new programme and historical programmes • Training of field staff to implement an effective QA/QC programme • Block-wide geological reinterpretation and exploration targeting at Al Jalamid • Data evaluation and geological modelling of sedimentary phosphate orebody • Providing a JORC compliant resource estimate • Developing a variety of exploration techniques to enhance phosphate exploration in the licence area. These techniques included standard geochemical sampling, regolith sample fraction analysis, gamma-ray scintillometer survey, and biogeochemical methods.
