Noranda from 1981 through its ownership of Brascan. Noranda Mines also operated in the UK in the early 70's with active exploration programs in Scotland and north Wales. The exploration program consisted of soil and stream sampling and limited Induced Polarisation and fluxgate magnetometer surveys. These programs were sufficiently advanced to give rise to drilling programs in Snowdonia (Hafod y llan) either side of the Watkin path, and also in Wester Ross just outside Locharron. Copper mineralisation was encountered in the Welsh drilling program but essentially nothing in Wester Ross. Drilling in Snowdonia was with a hand portable x-ray rig capable of reaching approximately 100 ft and in Wester Ross with a Boyles Bros. rotary rig drilling to approximately 1000 ft.
