The Northern Mine Remediation project began with the formation of the Yukon Mining Research Committee (YMRC) in 2012. As representatives of the mining industry they wanted to create a platform for industry, Yukon College, First Nations, and…

The overall goal of this project was to assess, in three stages, the use of fish otolith microchemistry as a potentially new monitoring tool to be applied around Yukon mine sites. High quality environmental assessments are critical to sound land and…

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…

In this review, we evaluate the challenges encountered and the adaptations required for the successful treatment of mine-impacted waters in cold climates with Passive Treatment Systems (PTSs). Engineered PTSs are modeled on natural wetlands, which…

Passive biological treatments have been proposed as an efficient and cost effective treatment of metal bearing water discharged from mine sites after closure. However, concerns are typically expressed around biological treatments and their…

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…

Four (4) pilot anaerobic bioreactors were commissioned at the Minto mine site in the summer of 2014 by Amelie Janin, NSERC Industrial Research Chair at Yukon College, and Capstone staff. Installation was completed on August 7th, 2014 and operation…

[T]his report explores a hybrid-applied solution: the use of saturated covers, which involve lifting an elevated water table into a tailing impoundment that maintains saturation within the tailing profile without allowing excess water directly along…

Northern Cross Yukon Ltd. is in the process of electing a treatment method for drinking water provision at their base camp situated in Eagle Plains, Yukon Territory (Canada). An experiment was conducted at the Yukon Research Centre for comparing…

"The use of biochar as a soil amendment for mine affected soil revegetation was established as a field experiment in 2012. While the objective of the present report is to synthesize data collected over the past two years of the program, some…

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…

As passive water treatment technologies are increasingly being considered as a part of mine site closure in Yukon, it is important for industry to share with the government the questions they have, and vice versa. Efforts are currently underway by…

"The goal of the project was to identify and understand the snow- and permafrost-related information needs of practitioners in the mining and transportation sectors in northern Canada, specifically in Yukon and the Northwest Territories, and to…

Heat transfer into the ground at highway culvert locations can lead to the thawing of permafrost, damaging infrastructure, shortening its lifespan, and increasing maintenance costs. The Dempster Highway in the northern Yukon experiences multiple…

"There are more and more researchers in the North who want their work to benefit northerners, and wonder if their results are relevant to the communities they work near or with. With the impacts of climate change being felt by those who live in…

Climate change is a significant challenge for northern communities, where the impacts of a warming climate are already having considerable effects (Huntington and Weller, 2005). Many people living in small, isolated communities in northern Yukon are…

This report presents the results of a project that aims to understand and, if possible, recommend actions to remediate the issues caused by the formation of sinkholes at km 82 and km 102-103 of the Dempster Highway. At km 82, this has resulted in…

The objective of this project was to identify landscape hazards in the Village of Mayo and nearby surroundings by compiling geoscience data from various field studies and scientific reviews (surficial geology, permafrost and hydrology). This data…
