This property is located one kilometre southwest of Harriet Harbour at about 228 metres elevation on the southeast coast of Moresby Island. It covers an area of 45-79 acres on Lot 78. It was part of a large block originally held by J.S. McMillan (see Copper Queen, 103B 035).

The showings were discovered in 1905-1906 and Crown-granted in 1910. Early work consisted of trenching and open-cutting. In 1956 Silver Standard Mines Limited drilled two packsack holes totalling 30 metres. The reserves were estimated at 10,886 tonnes.

The property is now part of Jedway Iron Ore Limited's large group of claims (see Jessie, 103B 026).

A small body of massive magnetite and a zone of disseminated chalcopyrite in a skarned, flat-lying lens of limestone occurs at the southern contact of quartz diorite of the Jedway Stock. The Jedway Stock is part of the Middle to Late Jurassic Burnaby Island Plutonic Suite. The limestone, which is an interlava unit within greenstones of the Vancouver Group, Upper Triassic Karmutsen Formation, is variably altered to skarn with replacement by garnet, epidote and actinolite. Disseminated chalcopyrite occurs over an area 100 by 70 metres. Chip samples of surface showings averaged 1.1 per cent copper and 34 grams per tonne silver (Bulletin 54, page 210).
