At the Blue Grouse showing, quartz with minor carbonate and siderite hosts minor chalcopyrite with scattered traces of pyrite and pyrrhotite. Veins crosscut Helikian Aldridge Formation (Purcell Supergroup) sedimentary stratigraphy and are related to the adjacent Empire (082GSW015) and Burt (082GSW018) occurrences. Old records indicate trenching and tunneling in the 1890's on the north side of Sand Creek.
In 1988, 10 drill Holes (C3-88, C8-G-1-88, D1-1-88, D2-2-88, D10-1, D10-2, D10-PP1, D10-PP2) totaling 544.8 metres, were completed on the Cedar 1A, Cedar 3A, Dogwood 1A, Dogwood 4 Groups for R.H. Stanfield (Assessment Report 19034). A vertical rotary hole was drilled on the Cedar 3 claim in 1988 and one hole was drilled on the Cedar 8 claim in 1988, at or near the G zone. Four rotary holes were drilled on the Dogwood 12 claim in 1988 and 4 holes were drilled on the Dogwood 10 claim in 1988. Road work and erosion control was completed over the Dogwood 9 and 11 claims and the Cedar 1,3 and 5 claims in 1988 and 1989. Only hole (C8-G-1-88) reached bedrock.
In 1992 a helicopter borne DIGHEM survey over the Balsam, Cedar and Dogwood claims of R. H. Stanfield (Bul River Mineral Corporation Ltd.) was completed (Assessment Report 23012). In 2017, an NI43-101 technical report for Purcell Basin Minerals Inc. defined exploration targets peripheral to the copper ore body on the Bull River Mine property (Assessment Report 37195). This work was facilitated by the processing of Dighem airborne EM (AEM) data acquired from 1991-1997 surveys. Processing and interpretation of the historic Dighem data identified several target areas of coincident EM and magnetic features. Figures 7, 8 and 9 show magnetic and resistivity coverage from the Bull River mine area southeast to the Elko community area (Assessment Report 37195).
Refer to Bull River (082GNW002) for details of the greater Bull River property which contained 25 MINFILE documented mineral occurrences as of September 2022. Also refer to Empire (082GSW015) for possible related information.
