Capsule Geology

The property is located on the west side of Lyell Island, Queen Charlotte Islands, northwest of Lyell Bay. The showings are less than 30 metres from shore.

The property was held in 1965 as the Marven group of 10 located claims. During the year Falconbridge Nickel Mines, Limited, put down 2 short packsack diamond drill holes; one bottomed in skarny magnetite at 27 metres; the other ended in greenstone at 23 metres. In 1964 a detailed magnetometer survey of the property was carried out by Placid Oil Company.

Pyritic magnetite replaces regionally metamorphosed greenstone and minor limestone of the Vancouver Group, Upper Triassic Karmutsen Formation. The rocks strike 150 degrees and dip about 50 degrees east.

Magnetite exposures and a magnetic anomalous area cover 14 square metres. A drill hole encountered magnetite skarn at 27 metres depth.
