Geochemical Considerations in Mine Waste Management Processes for Sustainable Mine Operation and Closure

Presenter: Valérie Bertrand

Successful mine site closure is rooted in early planning. This is crucial in the design and implementation of a robust mine waste and water management plan

Changes in Water Quality as an Indicator of Permafrost Degradation Near Communities in Nunavut

Presenter: Michelle Blade

Permafrost warming is projected to continue throughout this century, with active layer depths anticipated to increase up to one metre in parts of Nunavut.

Characterization of Arsenic and Antimony Minerals in Yellowknife Bay Sediments

Presenter: Katrina Paudyn

A sediment sampling program was conducted in Yellowknife Bay with the objective of characterizing arsenic (As) and antimony (Sb) mineralogy

Remobilization of Legacy Arsenic Contamination in Yellowknife Bay Sediments: Field and Laboratory Measurements of Arsenic Fluxes

Presenter: John Chételat

Yellowknife Bay, on the north shore of Great Slave Lake, received loadings of arsenic from gold mining during the 20th century.

Estimating Geochemical Background Concentrations of Arsenic in Soil in the Yellowknife Area

Presenter: Heather Jamieson

The estimation of geochemical background can be complex in areas impacted by point sources of atmospheric emissions due to unknowns about pollutant dispersion

Sustainable Yield Exploration for a Commercially & Recreationally Important Northern Fish Species, Lake Trout (Salvelinus namaycush), Through Data-Limited Modeling

Presenter: Hailey Chymy

Identification of stock reference points, which are valuable to management, is frequently complicated by a lack of adequate data.

Will Warmer Water Temperatures Associated with Climate Change Affect the Mobility of Arsenic from Mining-Contaminated Sediments in the Yellowknife Area, Northwest Territories?

Presenter: Brittany Astles

Lakes in the Yellowknife area (NWT) were exposed to atmospheric deposition of arsenic emissions from ore roasting at local gold mines.

Why Did the Caribou Cross the Road? Preliminary Results on the Relationship between Barren-Ground Caribou and Winter Roads

Presenter: Angus Smith

A number of populations of barren-ground caribou in Northern Canada are declining at alarming rates. Circumpolar declines in Rangifer have been attributed in part to increasing levels of human development.

Stability of Cantung Mine Tailings under Simulated Dry Stack Conditions

Presenter: Allison Surrette

Dry stack or filtered tailings is a relatively new method of tailings storage that is gaining popularity because it eliminates the need for conventional tailings dams.

Rates and Mechanisms of Bastnaesite Dissolution in Near-Surface Conditions at the Nechalacho Deposit, NWT

Presenter: Adriana Taylor

Canada does not currently produce rare earth elements (REE) but does contain resources.
