Sub-lethal Metal Toxicity Effects on Salmonids: A Review
A SkeenaWild report on heavy metals and the lowest concentrations of metals reported to cause sub-lethal effects on salmonids. Heavy metals are common pollutants of aquatic systems, often associated with human activities such as hard-rock mining. Fish are vulnerable to metals because of sensitive organs that are continuously in contact with water, and because metals are highly soluble in water.
Sub-lethal metal toxicity concerns for Unuk watershed salmonids from Seabridge Gold’s proposed KSM mine
A SkeenaWild report on the proposed KSM project’s predicted concentrations for 7 heavy metals to be released during ore-extraction operations into the salmon-bearing Sulphurets Creek and Unuk River, including relevant examples of the effect of concentrations known to adversely affect salmonids.
Acid Mine Drainage and Effects on Fish Health and Ecology
A U.S. Fish and Wildlife Service, Anchorage Field Office, report on acid mine drainage and the substantial risks that AMD poses to fisheries.
Seabridge Gold’s KSM Project Risk Analysis: June 2015 - issue 2
A report by Earthworks and Salmon Beyond Borders that questions the economic feasibility of the proposed KSM mine on the Canada/US border.
Letter of Concern from the Alaska Congressional Delegation to U.S. Secretary of State John Kerry
A letter of concern from the Alaska congressional delegation to U.S. Secretary of State John Kerry about the proposed development of several hardrock mines in British Columbia and water quality in transboundary rivers that flow from Canada into Southeast Alaska.
Video: Xboundary, from Salmon Beyond Borders
This video from Salmon Beyond Borders tells the important story of three rivers in British Columbia and Southeast Alaska that are in danger from mines frighteningly similar to Mount Polley.
Central Council of Tlingit and Haida Indian Tribes of Alaska Resolution Opposing KSM
Proposed KSM Project: Impacts
A SkeenaWild video on the Kerr Sulphurets Mitchell (KSM) mine proposed by Seabridge Gold Inc. The proposed mine would release metals into the Unuk watershed that would exceed levels known to have serious impacts on salmon.
Seabridge Gold’s KSM Project: Risk Analysis, November 2014
A new report from Salmon Beyond Borders and EarthWorks about the proposed KSM mine in northwest British Columbia near Southeast Alaska which found that the project’s remote location, low-grade ore, and geotechnical challenges make it risky, expensive, and unusually difficult to build.
Predicting Water Quality Problems At Hard Rock Mines: A Failure of Science, Oversight, and Good Practice
An Earthworks white paper summarizing and analyzing the groundbreaking studies by Ann Maest, PhD, and Jim Kuipers, P.E.: Comparison of Predicted and Actual Water Quality at Hardrock Mines: the reliability of predictions in Environmental Impact Statements, and; Predicting Water Quality at Hardrock Mines: Methods and Models, Uncertainties, and State-of-the-Art
Permitting of “Wet” Mine Tailings Impoundment Facilities in British Columbia and B.C.-Alaska Transboundary Watersheds
Statement of opposition by a large and diverse group of Canadians and Americans calling on the British Columbia government to halt the permitting of wet tailings facilities for new and proposed mines in B.C. based on the Independent Expert Panel recommendations on the Mount Polley mine tailings disaster.
US Copper Porphyry Mines
An Earthworks report compiling the record of pipeline, seepage control and tailings impoundment failures at operating copper porphyry mines in the U.S., and documenting associated water quality impacts.
Letter of Concern to the Alaska congressional delegation and the U.S. Department of State
A letter from Alaskan commercial and sport fishing groups, businesses, communities, tribes, conservation groups and individuals concerned that mining development in northwest British Columbia poses significant risks to downstream Alaskan interests, including water quality, customary and traditional fishing and hunting, commercial and sport fisheries and tourism. The groups request assistance and leadership from the Alaska Congressional Delegation and the U.S. Department of State to identify appropriate mechanisms to provide specific guarantees the natural resources Alaskans depend on will not be harmed by upstream development.
Salmon Beyond Borders
Salmon Beyond Borders provides information on the mining boom in northwest British Columbia that could threaten Southeast Alaska’s salmon, rivers, fishing and tourism jobs, and unique way of life.
A June 2015 report from the BC First Nation Energy and Mining Council on potential threats from tailings facility failures in northern British Columbia.
Central Council of Tlingit and Haida Indian Tribes of Alaska Resolution on Negative Effects of Canadian Transboundary Mining
Scientist Letter of Concern About Proposed Development in the Transboundary Watersheds
A letter from 36 scientists to Premier Christy Clark asking for her leadership to balance impending industrial development in northwest B.C. with the outstanding fish, wildlife and ecological values of this largely pristine region.
