Exploration geochemistry in British Columbia has up to now relied on traditional methods such as stream sediment and soil geochemistry to detect metals dispersed mechanically and hydromorphically from out cropping sources. These methods have proven to be highly effective and there has been a long and impressive history of discoveries using them. As exploration maturity […]
The primary objective of the Vancouver Island Geochemical Data Reanalysis Project was to stimulate mineral exploration interest in the region by providing the mining and exploration community with new, high-quality analytical information. Geoscience BC has supported the reanalysis of moss-trapped stream sediment samples originally collected in the late 1980s from creeks located on Vancouver Island […]
This project includes geological mapping and compilation of a large part of the 1:50,000 Burrell Creek map sheet 082E/09, located within the Columbia Mountains of southern British Columbia. The project is an extension to the north of the Deer Park map sheet project that was done in 2009. The Deer Park project focused on the potential for […]
This project was designed to add value to Regional Geochemistry Survey (RGS) data from the QUEST-South project based on an analysis of catchment size and levelling of the data for catchment bedrock geology. Data levelling will be based on exploratory data analysis (EDA) and ground proofing of the results against known mineral deposits and occurrences […]
The Mira Geoscience Advanced Geophysical Interpretation Centre has completed 3D inversion modelling, integration, and visualization of airborne gravity, magnetic, and electromagnetic data for Central BC (including QUEST-West and Nechako), and integrating it with the QUEST and QUEST-South project areas. This was undertaken for Geoscience BC as follow-up analysis of geoscience data. The objective of this work […]
The Mira Geoscience Advanced Geophysical Interpretation Centre has completed 3D inversion modelling, integration, and visualization of airborne gravity and magnetic data for the QUEST-South regional area in south-central British Columbia, Canada. This project was an enhanced continuation of the completed Geoscience BC inversion modelling project for the QUEST survey area. The objective of this work […]
Eskay Creek represents an unusual precious metal-rich, polymetallic volcanic-hosted sulfide and sulfosalt deposit located in the Iskut River area, British Columbia. The bulk of the mined-out deposit consisted of stratiform clastic beds and laminations of commonly graded sulfide and sulfosalt debris that were hosted by a thick interval of carbonaceous mudstone overlying felsic volcanic rocks. […]
Most carbonate-hosted, nonsulphide base metal (CHNSBM) deposits are derived from sulphide mineralization (MVT, SEDEX, Irish-type and vein-type deposits and, to lesser extent, skarns) by a supergene process. Several carbonate-hosted sulphide deposits in the Kootenay terrane, adjacent Cariboo terrane, and elsewhere in BC have near-surface Zn- and Pb-bearing iron oxide-rich gossans. Such gossans form when carbonate-hosted, […]
The basement of Quesnellia in southern British Columbia consists of several diverse lithotectonic assemblages, including the Harper Ranch Group, Apex Mountain complex, and Knob Hill complex, as well as the Anarchist, Kobau, Attwood and Chapperon assemblages. Scarce fossil ages and rare U-Pb zircon ages from some of these assemblages range from Devonian to Permian. However, […]
In order to further understand the geometry of the Nechako Basin for future exploration, the Mira Geoscience Advanced Geophysical Interpretation Centre (AGIC) conducted 3D constrained inversion modeling of airborne gravity and magnetic data. The constrained gravity inversion modeling incorporates existing processed seismic lines, wells, geologic mapping, test MT lines, and density measurements to guide the […]
