Boliden Somincor Advances Neves-Corvo Copper-Zinc Mine Development with Two 630-Metre Shafts

Published: Sep 14, 2026 09:12 (GMT+8)
Boliden Somincor has awarded Master Drilling a contract to construct two 630-metre-deep, 4.5-metre-diameter raisebored shafts at its Neves-Corvo copper-zinc operation in Portugal. The first 630-metre pilot hole has already been completed in just 24 days, setting a new Master Drilling record. While no incremental copper production guidance was disclosed, the project represents continued investment in deep underground infrastructure at one of Europe’s key operating copper mines.
