Aterian PLC - London-based, Africa-focused miner - Reports up to 4.0% of copper and 26.9 grammes per tonne of silver from the sedimentary-hosted copper target in the Azrar project in Morocco, following sampling. Also identifies copper mineralisation within the previously mapped Adoudouian sediments. Chair Charles Bray says: "Multiple styles of copper mineralisation and gold have been discovered in the recently awarded expansion areas. We now better understand that the sedimentary-hosted copper potential of this project likely offers greater scale than previously determined. These recent results from the Azrar project are both very encouraging, with the continuation of the sedimentary-hosted copper, and fascinating, with the identification of multiple other geological sources of copper mineralisation. The laboratory analyses from these new licences are very positive, with the multiple zones of quartz veins identified reporting good copper and unexpected associated gold values."
