Serval Resources said Thursday it completed geophysical surveys at its Somelo prospect in Botswana's Kalahari Copper Belt, with follow-up targets due by late October.

The Aim-listed company is running a work programme across two key prospects: Somelo, previously the PL 232 Cluster, and Sweet Thorn Pan, previously the PL 235 Cluster.

The programme combines audio-frequency magnetotellurics, high-resolution drone magnetic and orientation induced polarisation surveys at Somelo, plus a high-resolution drone magnetic survey at Sweet Thorn Pan.

Crews have finished the AMT, IP and drone magnetic work at Somelo. The drone magnetic survey at Sweet Thorn Pan is ongoing. Serval said the full programme, including associated fieldwork, is scheduled for completion this month.

Both prospects sit along an interpreted strike, particularly Sweet Thorn Pan, which has been drilled before. They are located near Khoemacau, a long-life copper/silver mine owned and operated by MMG with a total resource of 450-million tonnes at 1.4% copper and 18 g/t silver.

CEO, Robin Birchall said the surveys are central to the company's exploration strategy. "Geophysical surveys are a critical step in advancing our copper exploration strategy in the Kalahari Copper Belt. We are pleased that data acquisition has been advancing safely and in line with our planned scope," Birchall said.

He added that combining AMT, IP and high-resolution drone magnetics gives Serval a strong technical foundation to refine its geological understanding and define drill targets beneath Kalahari sand cover.

Serval has started processing the data. An integrated interpretation using the combined data sets is expected during October, with follow-up targets to be delivered around the end of that month.

The company will integrate the new data with existing information, including previously drilled holes at Sweet Thorn Pan under prior ownership, and define the most compelling targets for follow-up exploration, including drilling, subject to additional funding.

Processing of the data has already started, with integrated interpretation expected during October and follow-up targets due around the end of that month.
