Drilling Contractor Tender - Hammaslahti Copper-Zinc Project, Finland

Metals One (AIM: MET1), which is advancing critical minerals projects, announces that it has put out a tender for a drilling contractor to provide services for a 2,000m, 10-hole diamond core drill programme at the Company's Hammaslahti Copper-Zinc Project in Finland.

The planned drill programme will focus on E-lode, a key target at the project, as well as a greenfield area directly to the north of E-lode. Pending award of the contract and confirmation of rig availability, Metals One intends to commence drilling activities later this year.

The Hammaslahti Copper-Zinc Project is prospective for VMS mineralisation and contains the historical Hammaslahti mine which produced over 7Mt at an average grade of 1.16% copper, 1.55% zinc, 0.59 g/t gold and 5.2 g/t silver between 1973 and 1986.

Recent drilling by the previous owners identified previously unknown extensions to the Hammaslahti mine mineralisation with multiple intersections of high-grade massive sulphides. Examples of this extensional mineralisation include 3.4m at 11.5% copper and 3 ppm gold. The most recent diamond drilling programme in 2023 was successful in intersecting sulphide mineralisation in each of the eight holes drilled with one occurrence at only 75m depth.

Jonathan Owen, CEO of Metals One, commented:

"We are looking forward to commencing work at Hammaslahti, one of our two new Finnish copper projects, and are currently in the process of securing an experienced drilling contractor to assist with the drill programme. Reinterpretations of geophysical and geological data show significant potential for new VMS mineralisation which this drilling programme intends to test."
