The Josie group, consisting of the Josi, Poorman, No. 1, Annie and Annie Fraction claims, lies west of and adjoining the Centre Star property on the northwestern edge of the City of Rossland.

The Josie claim was apparently located by, R.E. Lemon in 1890 and Crown-granted to F.C. Loring in 1895. The British American Corporation Limited purchased the Josie and a number of adjoining claims in 1896 and development work was carried on for several years. The property was acquired in 1900 by Le Roi No. 2, Limited, an English company. Mining operations were carried out on 10 levels from a 396-metre deep shaft, and in several adits. Operations were continuous until January 1922 when the mine closed.

The Consolidated Mining & Smelting Company of Canada Ltd., owner of the adjoining Centre Star group, purchased the property in 1923 and operations were carried on until 1928 when the mine was closed. Lessees worked the property from 1932 until June 1942.

The Annie Crown Grant (Lot 730) hosts two major veins which are part of the "Main vein" system that forms a continuous well-defined regional fracture system striking 070 degrees for a length in excess of 1.0 kilometre. The Annie occurrence consists of the North Annie and the South Annie veins which strike west and dip steeply north. The veins were mined between 1898 and 1922 in conjunction with the Josie or LeRoi No. 2 mine (082FSW147).

The Annie claim is underlain by the Rossland sill, a mass of augite porphyry that intrudes siltstone, hornfels and hornfelsed siltstone of the Lower Jurassic Elise Formation, Rossland Group. The strata are intruded by the Early Jurassic Rossland monzonite, an east-trending biotite-hornblende-augite monzonite stock. The rocks are crosscut by late, lamprophyre and diorite dykes.

Mineralization in the main Annie veins consists of sulphide replacement of wallrock along well-defined fractures. The sulphides include pyrrhotite, chalcopyrite and pyrite in a gangue of altered country rock with lenses of quartz and calcite. The mineralization is described as the Rossland-type heavy sulphide ore, which is predominantly pyrite and pyrrhotite with a little chalcopyrite, and yields gold and copper.
