Villamaninite, a new mineral

Early in 1914 a parcel of copper-nickel-cobalt ore, weighing several tons, was received in London for valuation from the 'Cármenes mine, Spain'. This somewhat vague statement of locality refers without doubt to the group of mines in the district of Cármenes, province of León, situated about 6 km. E.N.E. of Viilamanín, a statisn on the railway from Gijon to León and about 40 km. N. of the latter city. The ores of these mines are described as consisting of sulphide minerals of copper, cobalt, and nickel in a gangue of dolomite.
