The role of the host rock in the formation of the Rice Lake gold deposits and implications for improved exploration in the area

The vein-hosted gold deposits in the Bissett area of SE Manitoba have long produced significant amounts of gold and the area has the potential for future substantial discoveries. Given the strong structural control on ore formation, a concerted research effort has been conducted on the structural geology of the deposits. However, there are several outstanding questions, including the genetic relationship between the host rock and the ore.

Three-dimensional simulation of Mississippi Lake for water quality management

Water quality concerns, such as algae blooms, are common in many aquatic systems across the country. Increasing development along waterfront properties and climate change are leading stressors causing poor water quality. In this project, an intern will apply a three-dimensional computer model to help understand how these stressors are contributing to poor water in Mississippi Lake, through a partnership between Queen’s University, the Mississippi Valley Conservation Authority and the Mississippi Lake Association.

Evaluation and improvements to quantitative models for predicting en route loss in Fraser sockeye salmon

Fraser River sockeye have become more difficult to manage due to climate change and increasing high adult in-river mortality events. Currently, managers use the difference between estimated lower river sockeye abundance at Mission hydroacoustic station and estimates of abundance attained on the spawning grounds through stock assessment; referred to as difference between estimates (DBE’s).

Hydraulic Fracturing Process: Mechanics, Monitoring and Optimization

Hydraulic Fracturing or fracking has been extensively used in the extraction of hydrocarbon fuels in unconventional reservoirs. This process bears significant economic and environmental implications. The partner, ExGeo, has been providing professional services to the petroleum companies to monitor the fracking process using microseismic signals. To improve the precision of field monitoring and optimize the fracking process, this research will first try to understand the mechanics of fracking through highly controlled and fully instrumented laboratory experiments.

Assessment of the Performance and Treatment Benefits of Primary Solids Microscreen Filtration with an Onsite Wastewater Treatment System

Onsite Domestic Wastewater Treatment and Reuse is emerging as a potential solution to the water shortages, eroding distribution infrastructure, and energy intensive treatment processes that are a fixture of the modern city. However, existing onsite treatment technologies fail to compactly treat water to a high enough quality for urban reuse without increasing per capita treatment energy use.

Process optimization for extraction of compounds from natural sources

The proposed research project aims to optimize the conditions for Carbon dioxide eXpanded Liquid Extraction (CXLE) which uses liquefied Carbon Dioxide (CO2) and ethanol as co-solvents for extraction of compounds from natural sources. Design alterations will be implemented to a Supercritical Fluid Extraction (SFE) unit at the partner organization (BioFoodTech) to perform CXLE and further increase the extraction amount as well as extraction rate.

Investigation of magma conduits and their relationships to Cu-Pd mineralization at W-Horizon of the Marathon deposit, ON, Canada

Copper and palladium (Cu-Pd) mineralization at the Marathon Deposit are associated with gabbro rocks. It is fundamentally important to be able to distinguish among the different types of gabbros, because only those of the Marathon Series are host to mineralization. This is accomplished through logging drill core, whole rock geochemistry and mineralogy.

Resource potential of the Post Creek Property, Sudbury, Ontario

Sudbury represents the site of a meteorite impact structure originally greater than 200 km in diameter and that formed 1.85 billion years ago. Despite the proven and potential economic benefits of resource development at Sudbury, there are still major outstanding questions concerning our understanding of the structure and its ore deposits. A series of objectives have been composed concerning the origin of Sudbury Breccia, host to footwall vein deposits, and Offset Dykes at the Post Creek locality and their mineralization.

Portable Sensor for rapid, onsite detection of bacteria in water

Harmful bacteria in drinking water can be a great threat to humans, causing diseases and possibly death. This project is aimed at determining the safety of drinking water for consumers, especially in communities where access to sophisticated laboratory facilities is limited. This research project will help to further develop a portable bacteria sensor for water, capable of determining the presence of harmful bacteria in water. The technology will offer faster analysis than the typical 1-2 day water analysis for bacteria.

Assessing Impacts of Climate Change on Laurentian Great Lakes Water Supply using Regional Climate Models

Several studies have shown that water levels of the Great Lakes would inevitably decline in a warmer climate. These studies were based on a modeling system that was not accounting for two-way exchanges of water and energy between the atmosphere and the earth surface, hence excluding key feedback mechanisms. The general objective of this project is to improve our understanding of the Great Lakes water resources and its sensitivity to climate change.
