The Shoo Fly (L.243) is located approximately 1500 metres inland from the head of Fanny Bay on Phillips Arm.
The area is underlain by a persistent band, greater than 12 kilometres long, of stratified metavolcanic and metasedimentary rocks of the Upper Triassic Quatsino and Karmutsen formations (Vancouver Group). The band trends northwest and separates Jurassic to Cretaceous Coast Plutonic Complex rock of two different compositions, diorite and granodiorite.
Locally, at the Shoo Fly (L.243) and Nella C (L.436) Crown grants, numerous shears are developed within the metasediments and metavolcanics. The lithologies include pyrrhotite skarn, magnetite skarn, and magnetite-chalcopyrite-pyrite skarn. One outcrop also contains trace amounts of scheelite.
In 1922, sampling within an adit on the Shoo Fly (L.243) Crown grant gave assay results of 52 per cent iron, 17.3 per cent silica, 2.2 per cent sulphur and 0.21 per cent phosphorous (Minister of Mines Annual Report 1922, page 243).
Exploration in 1983 failed to find this adit, but samples of skarn outcrops were taken. The best assay was 32.20 per cent iron, greater than 1 per cent manganese, 0.3260 per cent copper and 0.0720 per cent zinc. The value for manganese is uncharacteristic when compared to the other samples in the area (Assessment Report 12224).
The area was originally explored in the late 1890’s in conjunction with the nearby Doratha Morton (MINFILE 092K 023) mine. Numerous pits and shafts were completed in the area during the early 1900’s. In November 1982, Charlemagne Resources Ltd. optioned 17 reverted Crown grants. In 1983, Bute Joint Venture completed a program of rock and soil sampling, geological mapping and ground magnetic and electromagnetic surveys on the area as the Koop and Strider claim groups. Falconbridge Limited entered into an agreement with Charlemagne and in 1985 and 1986 carried out geochemical surveys comprising 1687 soil and 440 rock samples, airborne magnetometer and electro-magnetic surveys over 300 kilometres, and a ground electromagnetic survey over 200 kilometres on the Alexandra and adjacent ground. The area was prospected as the Cordero property in 1991 and 1992 by Ripple Creek Resources. During 1997 through 2000, Thurlow Resources conducted exploration programs on the area, renamed the DM and Picton properties, on the HY, LO, and FILL 2-19 claims. The programs consisted of soil sampling, rock sampling, and geological mapping. In 2008, Cuda Capital completed a 561.4 line-kilometre airborne magnetic survey on the area.
