Hoidas Lake

Hoidas Lake is a remote northern Canadian lake which lies approximately 50 kilometers north of Uranium City, Saskatchewan. Named in honor of Irvin Frank Hoidas, a Canadian soldier killed in action during the Second World War, [ [http://www.gwmg.ca/media/photos/hoidas-lake/irvin_hoidas_high_quality.jpg/view Irvin Frank Hoidas] ] it is the site of Canada's most advanced rare earth element (REE) mining project.

Hoidas Lake lies in the Northern Rae Geological Province, in the general vicinity of many of Saskatchewan's large uranium mines.

Mineralogy

The mineralogy of the Hoidas Lake rare earth deposit differs from most other such deposits in that it is hosted in veins of apatite and allanite. [Salvi S, Williams‐Jones A. 2004. Alkaline granite‐syenite deposits. In Linnen RL, Samson IM, editors. Rare element geochemistry and mineral deposits. St. Catharines (ON): Geological Association of Canada. pp. 315‐341] The deposit also contains a number of heavy REEs, such as dysprosium. This is important, as dysprosium is used in the manufacture of hybrid car components [G, Nishiyama. "Japan urges China to ease rare metals supply." 8 November 2007. Reuters Latest News. 10 March 2008 ] and there is an impeding shortage of the metal. [Cox C. 2008. Rare earth innovation. [Internet] .
