Boliden Somincor at Neves-Corvo: automation design lessons for underground engineers
Reviewed by Tom Sullivan

30 Second Briefing
Boliden’s Somincor operation at Neves-Corvo in Portugal’s Alentejo province, about two hours’ drive from Lisbon, is emerging as a leading European testbed for underground equipment automation. The polymetallic mine, acquired by Boliden in 2024, is advancing remote and autonomous operation of load–haul–dump fleets and drilling rigs in deep orebodies typical of the Iberian Pyrite Belt. For engineers, the site signals growing scope for high-automation underground layouts, communications infrastructure upgrades and workforce reskilling in what has traditionally been a conventional mining district.
Technical Brief
- Remote Alentejo location complicates on-site OEM support, pushing heavier reliance on telemetry and remote diagnostics.
Our Take
Across our mining coverage, Boliden consistently appears in electrification and automation pieces, from the ABB-supported Aitik tailings upgrades to the SEK 4 billion Garpenberg hoist project, signalling that any ‘new technology heights’ at Neves‑Corvo are likely to be embedded in a group‑wide digital and electric mine design philosophy rather than a one‑off pilot.
The recent Boliden Somincor–EDP–Greenvolt solar UPAC project near Neves‑Corvo shows that Portuguese operations are being used as a platform for on‑site renewable integration, which could materially change the power‑cost and emissions baseline for any new technology roll‑outs at the Somincor mine in Alentejo.
Boliden’s push into ‘green fleets’ across its European copper, nickel and zinc operations suggests that Neves‑Corvo and the wider Somincor complex in southern Portugal are strong candidates for early adoption of battery or hybrid mobile equipment, especially given the logistical advantage of being only a few hours by road from Lisbon for OEM and contractor support.
