The Buster occurrence is located at about 853 metres elevation, on a small knoll one kilometre southeast of Silverton, British Columbia.
No records could be located on work on the Buster property prior to 1970, except for production of 2 tonnes of ore in 1935. Work done on the claims hosting the Buster occurrence from 1970 to 1980 included trenching, one 122 metre diamond-drill hole, geochemical soil surveys, and ground electromagnetic and magnetic geophysical surveys. During this time two small adits were discovered in the northwest corner of the Winona claim group, covering the Buster occurrence.
The Buster occurrence is underlain by the Triassic Slocan Group, consisting of slate, argillite, quartzite, limestone, conglomerate and tuff. Porphyritic granite of the Middle Jurassic Nelson batholith outcrops to the south.
The Buster occurrence is mentioned in silver-lead-zinc vein deposits with or without gold and cadmium (Geological Survey of Canada Memoir 308, page 131). It is stated sphalerite was more abundant than galena and is classified as a fault-fissure lode. Other ore minerals may have included tetrahedrite, pyrargyrite, native silver and other unidentified minerals. Gangue minerals consist of varying proportions of quartz, calcite and siderite.
Production records indicate 2 tonnes of ore was mined from the Buster occurrence in 1935. This ore yielded 2364 grams silver, 31 grams gold, 173 kilograms zinc and 150 kilograms lead.
