The Rose claim, located on the southeast coast of Moresby Island, is on the ridge between Ikeda Cove and Collison Bay between 122 and 198 metres above sea level. The Crown-granted claim (Lot 1871) covers 33.64 acres. The showings extend from the ridge-top down the northwestern slope and just over the boundary onto the adjacent claims, Elva Nos. 3 and 4 and Maple. All claims are part of a large block held by Falconbridge Nickel Mines Limited (See Lily, 103B 028).

The showings were discovered by A. Ikeda and associates during the period 1901-1906 while prospecting in the vicinity of their Lily claim showings. Some stripping and prospecting ensued but the magnetite showings, being copper-poor, were of little interest at that time. The Rose claim was part of the Chrysanthemum Group of eight claims Crown-granted in 1913 (Lots 97, 100, 1868, 1869, and 1871 to 1874).

St. Eugene Mining Corporation, Limited, acquired the Lily and other claims in the mid 40's and drilled 2 holes for 24 metres in 1957 on the Rose claim. Silver Standard Mines Limited carried out a magnetometer survey in 1959. The Granby Mining Company Limited mapped the showings in detail in 1962 and Jedway Iron Ore Limited drilled 37 short holes totalling 1405 metres in 1965. Jedway started mining the property in 1966 on a royalty basis.

In 1985 and 1986, Falconbridge Limited conducted geological mapping, geochemical surveys and drilling in the area.

The Vancouver Group, Upper Triassic Karmutsen Formation, consisting of basaltic greenstones, is conformably overlain by limestones and argillites of the Jurassic to Triassic Kunga Group. The rocks are cut by dikes and sills of diabase, fine diorite porphyry, and diorite. Later dikes include andesite and felsite.

The Rose orebodies lie on the eastern end of a domal anticline adjacent to the Collison Bay Stock. This intrusive is dioritic in composition and is part of the Middle to Late Jurassic Burnaby Island Plutonic Suite. Bedding strikes 035 degrees and dips 20 to 30 degrees northwest. Faulting seems limited to small steep faults parallel to the strike.

The mineralized bodies consist of three parallel skarn bands, with widths up to 10.6 metres over an area 170 by 120 metres. Replacement is mainly in greenstone and consists of magnetite, garnet, chlorite and epidote with minor pyrrhotite, chalcopyrite and pyrite. A drill hole intersected 10.6 metres of 66 per cent iron with 0.34 per cent sulphur. A drill hole, about 200 metres to the southeast, intersected 2.07 grams per tonne gold over 1.5 metres (Assessment Report 14818).

The average grade of the magnetite ore is estimated at over 40.0 per cent iron with a sulphur content of about 1.0 per cent. Drilling in 1956 indicated about 508,930 tonnes of ore with a low stripping ratio. Total reserves of twice this amount may be recoverable at a much higher ratio (Bulletin 54, page 208).

Jedway Iron Ore Ltd. started mining this property on a royalty basis in 1966. Production figures are included in the Jessie Mine (103B 026) production. See Adonis (103B 027) and Lily (103B 028).
