This property, along with Ida (103B 038), is part of the Jim Group of recorded claims held by Jedway Iron Ore Limited. It is situated about 227 kilometres east of the southeast end of Huston Inlet on the southeast coast of Moresby Island. The showing is at about 335 metres elevation.

The deposit was discovered about 1906 by Messrs. McMillan, Watson and McEachern. Work included some open-cuts and two small adits.

In 1980 and 1981, Chevron Canada Resources Ltd. conducted geochemical, geophysical and geological surveys on the Huston claim.

An irregular skarn occurs over an area measuring 45 by 24 metres at the contact between basalts of the Vancouver Group, Upper Triassic Karmutsen Formation and quartz monzonite of the Middle Jurassic Burnaby Island Plutonic Suite. Overlying these are limestones and argillites of the Jurassic to Triassic Kunga Group. The skarn is silicified and is mineralized variably with magnetite, pyrite and chalcopyrite, with garnet, quartz and calcite gangue.

A grab sample of the skarn assayed 0.75 per cent copper and a grab sample of a silicified basalt in contact with magnetite skarn about 100 metres to the northwest assayed 4.4 grams per tonne gold (Assessment Report 9207).
