圣乔治矿业公司(St George Mining)在巴西阿拉萨(Araxa)项目以东1公里的螺旋钻取得一个高品位发现，在0.5米深处见矿13.5米，总稀土氧化物(TREO)品位12.34%，镨钕磁体稀土氧化物品位高达3.33%。

铌品位较低，这在意料之中，因为该地区位于巴雷罗(Barreiro)碳酸岩体的边缘。

公司正在计划后续钻探。

阿塞尔稀土公司(Axel Rare Earths)在巴西的卡拉道(Caladao)项目选冶试验表明，可以采用简单的淋滤方法提取稀土。

首批试验表明，磁体稀土元素回收率可达52%，既包括离子型粘土也包括非离子型粘土。

另外，镓的回收率可达25%。

阿塞尔正在设计一个简单的低成本两阶段堆浸工艺。

艾昂尼克稀土公司(Ionic Rare Earths)正在加快其在爱尔兰的工厂的产量。

该厂生产镝和铽以满足美国、欧洲和亚洲市场的“紧急供应需求”。

贝尔法斯特示范工厂自2024年1月以来一直在用废杂永磁体或生产废料来生产高纯度稀土氧化物。
