Argillites and arenaceous sediments of the Lower Jurassic Hall Formation (Rossland Group) are host to a number of closely spaced, quartz veinlets which follow the trend of the bedding. The stratigraphy is gently folded and the amount of quartz increases where small, flat rolls developed in the sediments. Arsenopyrite and minor chalcopyrite were identified in quartz veinlets. Quartz composed about 0.4 metres of the adit face. No reliable precious metal assays are recorded.
A total of 19 tonnes of ore were mined in 1932, 1934 and 1942 form which was recovered 560 grams of gold and 1,027 grams of silver.
