The Index occurrence is located at 1219 metres elevation between Desmond and Kyawats creeks, southeast of Keen Creek. Kaslo, British Columbia is located 22 kilometres to the northeast.

The Index occurrence was first located in 1905 by F. Helme. The property was worked intermittently until 1918. Index Mining Co. held the property under bond in 1919, with plans to extend the lower adit to intersect a mineralized vein at depth. Operations were terminated in 1920 without the vein being intersected. In 1948, the property was re-staked by Kaslo Silver-Lead Co. Thirteen claims were held which included the old Index and Metropolitan workings. A small vein was exposed by surface trenching. Property ownership was transferred to Kaslo Base Metals Ltd. in 1951, with acquisition of an additional claim and two fractional claims. The lower adit was extended in a southeast direction for 246 metres without intersecting the mineralized zone of the upper adits. In 1969, Andex Mines Ltd. acquired the Index property and surrounding ground. A total of 642 metres of surface trenching and 70 metres of surface diamond drilling in four holes were conducted. Further trenching was done by Andex Mines Ltd. in 1971. In 1972, trenching and 13.7 metres of rotary drilling in nine holes were done. Workings consist of three adits, totalling 396 metres. Workings of the Metropolitan lie about 305 metres above the Keen Creek road and consist of two adits of unknown length. Cream Minerals Ltd. sampled the property in 1997; a grab sample assayed 158.1 grams per tonne silver, 10.53 per cent zinc and 4.38 per cent lead (GCNL #174, 1997). In 2013, Agave Silver Corp. examined the area as the Kaslo property.

The Index occurrence occupies a narrow belt of tightly folded and contact metamorphosed Triassic Slocan Group metasediments within the Keen Creek reentrant. Metasediments, in order of importance, include slate, carbonaceous argillite, limestone, siltstone and biotite andalusite schist and are crosscut by several feldspar porphyry dikes and sills. Lithologies are flanked by hornblende potassium feldspar porphyritic granite of the Middle Jurassic Nelson batholith and potassium feldspar porphyritic granite of the Middle Jurassic Mount Carlyle stock.

A mineralized crush zone carries pockets and narrow veins of quartz and minor siderite with variable galena, sphalerite, arsenopyrite and pyrite. The zone strikes 125 degrees and dips 85 degrees to the southwest.

A total of 20 tonnes of ore is recorded mined intermittently from the Index occurrence. From this, 39,345 grams silver, 8863 kilograms lead and 1894 kilograms zinc were recovered. Production was from the upper two adits of the Index occurrence.
