In Photos: The Canadian Mining Boom You’ve Never Seen
When I met him, he had travelled to Ketchikan, Alaska, to meet with officials about the risk posed by the mining boom across the border in British Columbia. He stood on the boardwalk overlooking Ketchikan’s fishing fleet and waved his hands animatedly while he told me about how his culture — and southern Alaska’s economy — impact on the development of northern British Columbia, not only for mining, but also for the eventual settlement of many northern communities. The search for gold provides a good example of the technolog-ical changes that have accompanied mining practices over the last 140 years with respect to technology.

Life cycle impacts assessment of two gold extraction systems
Purpose Gold mining has historically and significantly contributed to the Colombian economy. Gold extraction in Colombia is mainly done through two techniques: open-pit and alluvial mining. In this study, the environmental impacts of both these mining systems were analyzed using the life cycle assessment (LCA) framework, including The history of British Columbia is the history of gold and the men who hunt for it. It was the Fraser River gold rush that led to BC becoming a colony and later a province.
