Book Description
The Sphaler Creek and Flood Glacier map areas comprise the Galore Creek area, located within the Coast Mountains between the Stikine River and Mess Creek. The large tonnage Galore Creek alkaline porphyry copper-gold-silver deposit is located within the area mapped. Results of regional mapping and sampling in 1988 are summarized in the report. This report and accompanying maps incorporates new data and revisions to the 1:50 000 geology and mineral occurrence map. The project was conducted to produce detailed geological maps and a database better able to understand the Galore Creek area and aid in making new discoveries.

Book Description
The Babine Mountains Recreation Area in west central British Columbia is a candidate for Class A park status. This report provides the results of a mineral resource potential study. The field based component of the study was carried out by a helicopter-supported two-person crew during late July and early August 1991. Office-based research and compilation continued into spring 1992. The report covers the geology of the area, past and present exploration and mining, mineral deposit types, the potential for undiscovered mineral resources, and a description of the Big Onion deposit.

Book Description
The Pinchi Lake regional lake sediment and water geochemistry survey described in this report covers an area of perceived high mineral potential in a region where exploration has previously been limited by extensive drift cover, poor exposures, and an insufficient geological database. Survey investigators collected lake sediments and waters from 413 sites in the study area and analyzed for 15 elements by atomic absorption spectroscopy and for a further 25 elements by instrumental neutron activation analysis. This report describes the survey areas (location, access, physiography, surficial and bedrock geology, mineral deposits), survey methodology, and quality control procedures, and presents a preliminary interpretation of the data obtained, notably for gold. New areas for prospective porphyry-style gold/copper and molybdenum deposits are outlined, and recommendations are provided for gold exploration in the study area. Appendices contain analytical data.

Book Description
Since 1859, the central Quesnel belt region of interior British Columbia has been the site of significant placer gold production. The identification of bedrock source areas for the placer gold and definition of the various mineral deposit types in this region are the main objectives of this field study. The study describes the regional geology, the geology of the central Quesnel belt (sedimentary units, volcanic successions, overlap units, continental clastic and volcanic deposits, intrusive suites), the region's geochronology and palaeontology, geochemistry, geologic structure, and metamorphism. It concludes with a section on economic geology of the region, discussing lode deposits, placer gold deposits, and regional geochemical studies.

Book Description
The Stikine project area covers part of a mineral-rich belt near the Alaska panhandle/British Columbia border. The area includes important precious and base metal deposits such as Eskay Creek, and was selected for this study due to its high mineral potential and outdated geological database. This report, the result of four seasons of mapping in the area (1988-91), describes the area's regional tectonic setting and stratigraphy, intrusive rocks, structural geology and metamorphism, and economic geology (types of mineral deposits, timing of regional metallogenic events, isotope geology, exploration activity, mineral potential).

Book Description
The Kechika Trough in the Rocky Mountains of northern British Columbia is host to numerous sedimentary exhalative barite-lead-zinc deposits collectively known as the Gataga mineral district. This report summarizes the bedrock mapping component of a multi-disciplinary study of the northern part of this basin. Field data for this component were collected during the summers of 1994 to 1996. Sections of the report describe the study area's lithologic units (Proterozoic to Cambrian strata, intrusives), geologic structure (faults, folds, cleavage), metamorphism, and economic geology (mineralization, skarns, veins, sulphides).

Book Description
The Cowichan Lake area lies at the southeastern end of the Vancouver Island Ranges and is characterized by fairly rugged topography accentuated by glaciation. The area is divided into two regions of differing structural style by a major thrust fault running along Cowichan Lake. This report introduces the geological setting of the areas and describes its lithology and stratigraphy, structure and tectonics from the Late Devonian to the Eocene, and the metamorphism and alteration of the area's sedimentary and igneous formations. The final section of the report reviews the history of mineral exploration in the area, outlines the regional metallogeny, and classifies the mineral deposits found in the area. The appendices include tabulated data, descriptions of mineral occurrences and fossils, and a summary of assessment report work recorded within the area.
