Aterian PLC on Wednesday said it has received high-grade assay results for gold at its Tata and Azrar projects in Morocco.

The London-based miner focused on Africa said the data came from historical airborne geophysical surveys, as part of its ongoing portfolio-wide targeting, rationalisation and prioritisation process.

The surveys covered more than 250 square kilometres, identifying five potential copper target areas at Azrar and four at Tata. These areas will now undergo follow-up groundwork.

Chief Executive Officer Simon Rollason said: ‘’Several targets are coincident with known mineralised occurrences at Azrar, which include 0.82 [grammes per tonne of gold] and 0.63% [copper] over 9.0 metres from surface chip channel targeting northerly strike quartz veins, in addition to previously identified targets such as the Ougri sedimentary-hosted copper target, where rock chip samples reported up to 2.92% [copper] and 16 [grammes per tonne of silver] over an 800 metre strike length of a 1.4 kilometre basal Adoudou Formation target. One target, where no prior exploration has been undertaken, is focussed over an apparent 4.4 kilometre strike length of basal Adoudou sediments.

’’At Tata, where 32 kilometres of prospective mineralised strike length has been mapped, four target areas have been delineated, coinciding with early positive copper indications within the lower Adoudou Formation. One target (Tata Cu-02) has not been explored, with surface copper reported from the other three geophysical targets. In addition, results will aid our understanding of the sedimentary basin architecture, allowing us to target potential areas of interest further and contextualise field-derived datasets better.

‘We look forward to updating shareholders with results from the upcoming field programmes when they are received.’’

Shares in Aterian were up 6.4% at 50.00 pence each in London on Wednesday morning.
