This property consists of one claim, Lot 2600, covering 29.97 acres. It is located one kilometre southwest of Harriet Harbour at 305 to 335 metres elevation on the southeast coast of Moresby Island. It was part of a large block originally held by J.S. McMillan (see Copper Queen, 103B 035).

The showings were discovered around 1907 and it was part of the eight claim Eagle Tree Group owned by C.H. Park in 1908.

Work at the time included a 67-metre crosscut adit, a 5-metre shaft and surface work. The claim was Crown-granted to J.S. McMillan in 1914. In 1956 Silver Standard Mines Limited drilled 12 EX holes totalling 568 metres. The property remained in the McMillan family.

Massive and disseminated bodies of magnetite, pyrite and chalcopyrite occur along a sheared contact between Vancouver Group, Upper Triassic Karmutsen volcanics and quartz diorite of the Jedway Stock. The Jedway Stock is part of the Middle to Late Jurassic Burnaby Island Plutonic Suite. The contact trends 065 degrees and dips steeply south.

In 1956, the mineralized zone was reported to be over 100 metres long and 6 metres wide. Samples averaged 2.6 per cent copper, 3.5 grams per tonne gold and 34.3 grams per tonne silver (National Mineral Inventory Card 103B6 Cu7).
