AbstractThe Granite Mountain area, located in south central British Columbia, includes the Gibraltar Mine (porphyry Cu-Mo deposit). Most of the map area is underlain by till of the Late Wisconsinan Fraser Glaciation. During deglaciation, meltwater channels were eroded in the hillsides of Granite Mountain and the mountainous ridge north of the mine indicating that ground at high elevation was deglaciated first. Meltwater was generally routed to the north through two dominant corridors: one in the west, in the region trending north from Cuisson Lake and a second one in the east, in the valleys of Ben and Skelton lakes and Arbuthnot Creek. Glaciofluvial sediments deposited during ice retreat represent potential granular resources. A glacial lake and associated delta are mapped north of Ben Lake from aerial photograph interpretation. At the western edge of the map area, large landslides most likely in bedrock and unconsolidated sediments occurred along the bedrock escarpment of the Fraser River valley. Anthropogenic deposits including wet and dry tailings surround Gibraltar Mine.
Summary(Plain Language Summary, not published)
The Targeted Geoscience Initiative (TGI-4) is a collaborative federal geoscience program that provides industry with the next generation of geoscience knowledge and innovative techniques to better detect buried mineral deposits, thereby reducing some of the risks of exploration. The surficial geology map of the Gibraltar Mine area in British Columbia depicts the distribution of the different types of unconsolidated sediments that were deposited by glaciers during the last glaciation and sediments that were deposited since the melting of the glaciers. Also, it shows the different terrain forms (landforms) that were created by glaciers and meltwater derived from their melting. This map has a wide range of applications from the search of granular resources to mineral exploration and environmental geology. For example, the map indicates the presence of potential granular resources within 20 km west and northeast of the mine.
