经过地质部门连续10余年的勘探,在竹山县庙垭境内发现一大型铌——稀土矿床。现已查明五氧化二铌92.95万吨(国家规定5000吨以上为大型矿床),氧化稀土储量121.51万吨(国家规定500吨以上为大型矿床),其矿品位均超过国家规定的工业开采标准,潜在经济价值(80年不变价)为2788亿元,资源可靠,开发前景相当广阔。
After geological exploration for more than 10 years, a large-scale niobium-rare earth deposit has been found in Miaoya, Zhushan County. It has been identified niobium dioxide 929500 tons (the state regulations for more than 5000 tons of large deposits), rare earth oxide reserves of 121.51 tons (the state provisions of 500 tons or more for the large deposits), the ore grade exceeded the national industrial mining standards , The potential economic value (unchanged at 80 years) is 278.8 billion yuan, with reliable resources and a promising prospect for development.
