The objective of this study is therefore to evaluate the impact of freeze-thaw cycles on oxygen migration within saturated covers over tailings, by simulating a tailings cover system in the laboratory through column experiments. Covers for waste rock are not evaluated, but may be the topic of future research. This report details the selection of experimental methodology, background literature, experimental design, and details the results of the column experiments.--from Introduction

Environmental and socio-economic effects assessment ensures that the effects of development activities are considered before they happen and that significant adverse effects will be mitigated. Dr. Amelie Janin, NSERC Industrial Research Chair in Mine Life Cycle at Yukon College taught this course over the Winter 2017. Through discussions with a series of guest speakers and with the instructor, the students were tasked to reflect on the environmental assessment process in Yukon and to write short essays. The essays have been compiled under one document.

The goal of Yukon Passive Water Treatment Workshop was to foster discussions between mines environmental personnel, regulators, project managers, consultants, design engineers, and other affected stakeholders to identify the gaps that need to be addressed. The specific objectives were: 1. Facilitate communication between stakeholders and set up an environment for constructive discussion on progressing passive water treatment systems in the Yukon. 2. Identify constraints, gaps, and reservations that industry, regulators, and researchers encounter. 3. Increase knowledge-sharing 4. Encourage the development of plans on how to address these issues. This event was planned and organized by Amelie Janin, NSERC Industrial Research Chair at Yukon College, Bob Truelson, Manager, Water Quality Section with Environment Yukon, and Martin Haefele, Permitting Manager at Capstone Mining Corp. Forty-seven participants attended the workshop, representing the various stakeholders.
