Tests Indicate Low Mining, Process Costs At Wyoming Mining Project

PHOENIX, AZ - American Rare Earths Ltd, reported that its Halleck Creek rare earths elements project in Albany County, Wyoming, metallurgical tests have paved the way for a potentially low-cost mining and processing operation using conventional technology. The company, which is also progressing the La Paz REE project in Arizona, is positioning itself to be a key player in the North American supply chain for the renewable future.

The metallurgical tests, conducted by Wood Australia, show that Halleck Creek has favorable characteristics on a number of counts. These are: Low ore strength: the ore can be liberated easily, with the ore strength ranking in the lowest 14th percentile of more than 1,300 deposits globally. This requires minimal energy use; Ore abrasiveness is below average; The ore will require less coarse grinding at the processing plant, meaning another level of energy expenditure and the opportunity to increase capacity; and These factors will make possible a simplified flow sheet reflecting lower capital cost outlays.

Managing Director, Chris Gibbs, said, “These test results indicate there could be significant energy savings due to the ore softness. Simply put, the easier the ore is to crush and grind, the lower our operating costs will be. It will also enable higher throughput rates and efficiencies as the comminution circuit is so often the limiting factor for plant capacity. And, apart from energy savings, the less abrasive ore will lead to reduced wear and tear.”
