GRM-services Oy (business ID 2738190-7, Vantaa) is a Finnish contracting and consulting company for geophysical and rock-mechanical measurements, serving mineral exploration and civil engineering. It is owned by its management and staff, says it has completed more than 600 projects in 12 countries, and names the Nordic countries and the rest of Europe as its main market. Its Portuguese permanent representation, GRM-Services Oy – Sucursal em Portugal (NIF 980640334), is registered in Amadora.
GRM-services was registered in Finland in January 2016 and is based in Vantaa, in the Helsinki metropolitan area. It sells complete geophysical and rock-mechanical measurement services — the ground surveys that mining companies use to find and delineate ore bodies, and that civil engineers use to assess rock before tunnelling or foundation work. It also rents out professional geophysical measurement equipment, with expert support and training. The company says its key people have long experience at home and abroad, that it has completed more than 600 projects in 12 countries, and that it is a member of the Ground Geophysical Survey Safety Association (GGSSA).
In Portugal it is registered as a permanent representation, GRM-Services Oy – Sucursal em Portugal (NIF 980640334), at Praceta Libânia do Carmo Galvão in Amadora, on the north-western edge of Lisbon. The branch’s registered purpose covers geophysical surveying and related services in Portugal and abroad, including the manufacture, hire and maintenance of survey equipment.
Portugal’s mining sector is tied closely to the Nordics: Boliden owns the Neves-Corvo copper-zinc mine through Somincor, and the Iberian Pyrite Belt and the lithium-bearing areas of the north are drawing renewed exploration. Specialist Nordic exploration contractors such as GRM-services bring survey methods developed in Fennoscandian exploration to Portuguese ground. A registered Lisbon-area branch points to recurring work here rather than a single campaign.
