Weir is the mining consultancy

Based on additional coring and chemical analysis, Weir International has also determined that the size of the Company's REE Exploration Target has increased almost 50% to 0.9 – 1.2 million tons of total rare earth oxides ("TREOs") from its initial Target in May of 0.6 – 0.8 million tons. As perspective, the United States has an average domestic consumption of roughly 10,000 tons per year of REEs over the last ten years.
