Ottawa diverts $3M rare earths sale from Chinese firm in 'case of elevated interest for Canada'
The federal government has brokered the sale of $3 million in stockpiled rare earths mined in the Northwest Territories by Vital Metals (ASX: VML), the company said Monday, as Canada moves to keep its critical minerals out of Chinese hands....

The crustal abundance of light REE about the same as copper and even the less abundant heavy REE are much more abundant than precious metal such as gold.
Most working REE mines are in carbonatite-related deposits, usually where initial mantle derived and magmatic enrichments of light REE have been further upgraded by metamorphic, hydrothermal or weathering processes. Other mines produce loparite from nepheline syenite and monazite from mineral sand placer deposits. Ion adsorption clays, in which the REE are adsorbed to clay particle surfaces and released by leaching, are the most important sources of heavy REE. REE are usually mined by conventional open pit methods, except for the ion adsorption clays in China that are now usually mined by in-situ leaching.

What Are Rare-Earth Metals?
Rare-earth metals are a set of seventeen elements, including scandium, yttrium, and praseodymium. These metals have a wide variety of applications, ranging from magnets, lasers, GPS satellites, photoluminescence, computer components, lighting, and electronics.
Unlike gold, which truly is scarce, rare-earth metals are plentiful in the Earth’s crust. However, these elements tend to be dispersed and mixed in with other elements, making extraction and separation expensive, difficult and fraught with environmental risks.
CANADA’S CRITICAL MINERALS
The list, developed by Natural Resources Canada in cooperation with a team representing various federal, provincial, and territorial entities, is an essential step toward putting the nation in a position to meet the goals set out by the Canadian Minerals and Metals Plan, or CMMP, which aims to make Canada the world’s leading mining nation.
The list consists of 31 materials deemed critical to Canada:
Aluminum
Antimony
Bismuth
Cesium
Chromium
Cobalt
Copper
Fluorspar
Gallium
Germanium
Graphite
Helium
Indium
Lithium
Magnesium
Manganese
Molybdenum
Nickel
Niobium
Platinum group metals
Potash
Rare earth elements
Scandium
Tantalum
Tellurium
Tin
Titanium
Tungsten
Uranium
Vanadium
Zinc
While there is some overlap found between Canada’s list and that of the US, Canada’s list is perhaps less focused on materials the nation will struggle to maintain a reliable supply of and more focused on those Canada will be able to source for itself and its allies.
