Understanding the potential impact of rare earth elements in aquatic systems in the NWT
Principal Investigator: McGeer, Jim
Licensed Year(s): 2016 2015 2014
Summary: The objectives of this research are to evaluate the relative sensitivity of northern aquatic invertebrates and northern ecosystems in comparison to southern species and environments. The focus of comparisons is in relation to the toxicity of rare earth elements. Approximately 3 to 5 sites will be chosen for detailed samplings and examples could include (Pontoon Lake, Trappers Lake and Tibbitt L...

Geochemical and mineralogical controls on the low-temperature aqueous mobility of rare earth elements (REE) in mine waste from the Nechalacho deposit, NWT
Principal Investigator: Purdy, Colin
Licensed Year(s): 2012
Summary: The objective of this study is to determine what controls whether rare earth elements are mobile under low temperature and moderate to high pH conditions. Four 55 gallon barrels cut in half will be set up at Thor Lake with mine tailings in them. The tailings will be allowed to weather in the local environment. Samples of the tailings and waters in them will be sampled at the beginning, and then...

Petrogenesis of the Blachford Lake Intrusive Suite
Principal Investigator: Mumford, Thomas R.
Licensed Year(s): 2011 2010
Summary: With increasing activity at the Nechalacho Rare Earth Element Deposit a better geological understanding of the setting of the mineral deposit is required. This study is fundamentally concerned with how and why the deposit exists. This is achieved by studying the entire Blachford Lake intrusive suite (>300 km2), the igneous system which generated the deposit. From this, a petrogenetic framework wil...

Blatchford Lake, NT Airborne Gravity Gradiometry Survey
Principal Investigator: Miles, Warner F.
Licensed Year(s): 2011
Summary: The objective of the airborne survey is to acquire high-resolution airborne gravity gradient and magnetic data. Airborne gravity gradiometry surveys measure small variations in the rate of change of the gravity field due to lateral variations in the mass and density of underlying bedrock. Aeromagnetic surveys measure magnetic properties of bedrock and are one of the tools used in geological mapp...

Granitic pegmatites of the Canadian Cordillera
Principal Investigator: Groat, Lee A.
Licensed Year(s): 1995 1994 1993
Summary: Rare elements such as lithium (Li), beryllium (Be), rubidium (Rb), niobium (Nb), cesium (Cs) and tantalum (Ta) are commonly found in structures known as pegmatites. The researchers will document the western Canadian locations of pegmatites which have these important minerals. Included in this survey is the pegmatite located in the Selwyn Mountains of the NWT....
