The purpose of this report is to assess the water quality and aquatic ecosystem data gathered to date and to recommend water quality objectives specific to the Toboggan Creek watershed. Designated water uses, to be protected by water quality objectives, are...

Predominantly all wastes, both tailing and blasted rock, contain pyrite and are classified acid generating. Acid generation occurs within waste rock fills around the property however not within tailing thus far due to sub- aqueous disposal of the product....

The Equity Silver Mine operated between 1980 and 1994, producing silver, gold, and copper from three open pits and a small underground operation. Mine components include a flooded tailings impoundment constructed from till and waste and quarried rock. This...

Site-specific water quality guidelines for the Skeena River at Usk for the purpose of national reporting (May 2005). This document is one in a series that presents ambient site-specific water quality guidelines (SSGs) for British Columbia and the Yukon....

The Equity Silver Mine operated between 1980 and 1994, producing silver, gold, and copper from three open pits and a small underground operation. Future liability is important at the site due to the environmental risk and high cost of treating acid rock...

Historical water quality data presented for the Skeena River watershed are divided into nine subsequent sections, corresponding to the nine major watershed reaches. Each section is divided into 6 subsections: hydrology, land use history, water withdrawals,...

An assessment of discharge regulation, aquatic monitoring, and aquatic impacts related to Bell and Granisle Mines.

This Assessment Report considers the proposed Morrison Copper/Gold Mine Project’s potential to cause significant adverse environmental, economic, social, heritage, and health effects. It identifies measures to prevent or reduce adverse effects, and sets out...

This dataset contains elements of the Morrison Copper/Gold mine application which are relevant to salmon in the Skeena watershed. The document itself and its appendices constitute Pacific Booker Minerals' application for a certificate under the British...

Sampling at fish index sites was conducted at five locations in Foxy and Buck creeks for Equity Silver Mines Ltd. from September 1988 to 1991.

Equity mine water quality data from 2011 to 2016. Data includes pH, conductivity, anions and nutrients, metals, and total suspended solids. This is a subset of the BC Environmental Monitoring Stations (EMS). Visit...

This underground mining project will be located in the Bulkley-Nechako Regional District and in the traditional territory of the Wet'suwet'en people. Included in this dataset are the executive summary and elements of chapter six which deal directly with the...

Approximately 800 000 m3 of acid mine drainage (AMD) is generated per year at the Equity Silver Mine southeast of Houston. This AMD would have devastating effects on the Bulkley River if it was allowed to flow untreated from the property for a prolonged...

The focus of this report is on Goldcorp’s one closed site in Honduras (San Martin), one closed site in Mexico (Nukay in Guerrero), four closed sites in the United States (Dee and Daisy in Nevada, Rand in California, and Golden Reward in South Dakota) and...

This review is a qualitative assessment of existing data and a review of relevant primary literature. The objective of this review is to assess the potential effects of elements released from the Morrison Copper/Gold Project on fish assemblages in Morrison...

This report illustrates and discusses the temporal trends in groundwater and surface water chemistry before, during, and after mining. It is based on empirical and predicted geochemistry and on the latest groundwater modelling using the MODFLOW model.
