Rare earth projects often have a high value. A tonne of 98% refined ore is worth in the order of US$40 per kilogram which would rise to an average US$200 a kilogram for a fully refined 99.99% purity basket of Light Rare Earths. This value would rise even higher if the more valuable Heavy Rare Earth components are added into the calculation. Early indications from the initial RC drilling completed at Mrima Hill in Kenya by Pacific Wildcat Resources is that this rare earth deposit has a favourable proportion of the more valuable heavy rare earths (including yttrium) of almost 10%.
