The Neosho property is located about 1.6 kilometres west of Kootenay Lake and about 1 kilometres north of Coffee creek at an elevation of about 1036 metres. A branch road 18 kilometres long was built to the property from the No. 1 mine road.

The country rocks are limestone, argillite and staurolite schist of the Mississippian to Lower Permian Milford Group. Granite of the Nelson Intrusions occurs immediately to the south. Intrusive sills or dikes of gneissic granite occur throughout the area north of the contact. The limestones strike approximately north and dip to the west. The Neosho vein, varying in width up 0.76 metres, follows the bedding in the limestone. The vein is not presently exposed but is reported to have been in a zone of sheared and oxidized schist (with limestone layers) containing galena, sphalerite and locally wire silver.

Small amounts of high grade silver ore are reported to have been shipped from this property in 1889 and 1890. The Neosho claim was Crown granted to the Neosho Mining Co. in 1892. By 1895 the workings consisted of a shaft over 30 metres deep and 76 metres of tunnel. Neosho Mines Ltd. acquired the Neosho, Normandy and several other claims in 1928 but very little work was done and the property lay idle for the next 20 years.

S. Hallgran obtained the claim from the Crown in 1948. Leasers worked the property in 1949. Privateer Mines Ltd. obtained an option to purchase the property but after a preliminary investigation by the company engineer in May 1950, it was decided that the option should be dropped.

Ten tonnes were shipped in 1922 and a further 135 tonnes were shipped in 1949 and 1950. From this 104,785 grams of silver, 3,508 kilograms lead and 7,808 kilograms of zinc were recovered.
