This property consists of one Crown-granted claims Lot 82, covering 40.63 acres. It is situated at 61 metres elevation about 1 kilometre southwest of Harriet Harbour on the southeast coast of Moresby Island. It is part of a large group originally held by J.S. McMillan (see Copper Queen, 103B 035).

The showing was discovered around 1906 and Crown-granted to McMillan in 1909. It was explored by surface work and a 4.6-metre shaft. In 1908, 122 metres of drilling was done on this and the adjoining Modoc claim (103B 031). Since then the only significant work was done in 1956 when Silver Standard Mines Limited drilled several short packsack holes totalling about 122 metres.

The property has remained in the McMillan family and in 1968 was held by Paul McMillan.

A body of magnetite, with garnet and veinlets of pyrite and chalcopyrite, occurs in fractured greenstone of the Vancouver Group, Upper Triassic Karmutsen Formation at the contact of hornblende diorite of the Jedway Stock. The Jedway Stock is part of the Middle to Late Jurassic Burnaby Island Plutonic Suite. The magnetite body, measuring 24 metres long and 1.2 to 2.4 metres wide, trends westward from the contact and dips north about 40 degrees. Assays run about 1.5 per cent copper, 3.4 grams per tonne gold and 24 grams per tonne silver (National Mineral Inventory Card 103B6 Cu5).
