Abstract
Surficial geological mapping and drift exploration work was undertaken in 1996 by the BC Geological Survey Branch northeast of Kamloops in NTS map sheets 82M/4 (Adams Plateau) and 82M/5 (North Barriere Lake). The map area encompasses some 2000 square kilometres of rugged drift-covered terrain, overlying economically interesting Devono-Mississippian low-grade metamorphic rocks of the Eagle Bay Assemblage. Previous mining operations in volcanogenic sulphide-barite deposits such as Samatosum Mountain and Homestake confirm the high mineral potential of the region. Published bedrock mapping of the area by Schiarizza and Preto (1987) and recent successful mineral discoveries in correlative rocks located in the Yukon (i.e. Kudz Ze Kayah and Wolverine) provided the primary impetus for renewed mineral exploration activity in this area for VMS type mineralization. This exploration included mineral deposit studies (Hoy, 1997), a stream water survey and geochemical orientation (Sibbick et al., 1997), as well as 1:50,000 scale surficial mapping and drift exploration sampling. The latter two components provide vital information for mineral exploration in regions where unconsolidated sediments of variable thickness mask the underlying bedrock (Bobrowsky et al., 1995). The purpose of this paper is to describe surficial mapping methods and preliminary results focusing on the types of sediments observed, including their distribution and general character. Terrain maps showing the distribution of sediment type, estimated thickness and other terrain constraints are available at 1:50,000 scale. Data pertaining to the drift exploration component of the Quaternary investigations, including till geochemistry and pebble lithology studies appear elsewhere (Bobrowsky et al. 1997).
