SanJuan盆地的2个铀矿床现在正由铀资源公司和其下属水资源公司(1998年先期开始)开发建设。2个矿床都将采用先进的地浸(ISL)采矿技术。铀资源与水资源公司在所开发的2个矿床上现拥有成本低于39美元/kgU的可回收铀储量估计约14583t。SanJuan盆地的铀资源是美国任何一个成矿省中最大者。1997年3月,负责推荐生产执照发放的核管理委员会完成了矿床场地的最终环境影响报告(FEIS)。FEIS历经9a的努力方领取到执照并获准开发矿床。侏罗系莫里森组Westwater峡谷段岩性为细～粗粒的长石砂岩,夹持于SanJuan盆地内潮湿冲积扇环境下沉积的几乎遍及整个盆地的粘土岩中。原生的层状铀矿体是富腐殖酸盐、同生的板状矿床,赋存于Westwater峡谷段,它随后再活化成卷状前锋。从侏罗系沉积以来,盆地内发生了2个阶段的再活化作用,形成了可地浸的、不含有机物碎屑的单金属铀矿卷。鉴于地浸开采,这2个矿区的地下水恢复工作要达到与采矿前基本条件相一致的水质。地浸采矿的开发提供了一个环境上可行的、可降低成本的铀提取方法。从新墨西哥州这块土地上铀资源与水资源公司预期每年生产385～1156tU。
Two uranium deposits in the SanJuan Basin are now under development and construction by Uranium Resource Company and its affiliated water company, which started early in 1998. Both deposits will use advanced ground immersion (ISL) mining technology. Uranium Resources and Water Resources The recoverable uranium reserves currently owned by the Company at less than $ 39 / kgU in the two deposits it has developed are estimated at about 14,583 t. Uranium resources in the Sanjuan Basin are the largest of any metallogenic province in the United States. In March 1997, the Nuclear Regulatory Commission responsible for recommending production licenses issued the Final Environmental Impact Report (FEIS) for the deposit site. FEIS, after 9a’s efforts, obtained a license and was allowed to develop the deposit. The Jurassic Morrison Formation Westwater canyon is a fine-grained feldspar sandstone sandwiched between clay rocks deposited throughout the basin under wet alluvial fan environments in the Sanjuan Basin. The native layered uranium ore body is a humic acid salt, symbiotic plate-shaped deposit that occurs in the Westwater Gorge section and is subsequently reactivated to a coil forward. Since the Jurassic sedimentation, two stages of reactivation have occurred in the basin, forming a single-metal uraninite ore that can be sub-leached and does not contain organic debris. In view of the leaching of groundwater, the recovery of groundwater in the two mines has to meet the water quality consistent with the basic conditions before mining. The development of immersion mining provides an environmentally viable uranium extraction method that reduces costs. Uranium Resources and Water Resources, a unit of land from New Mexico, is expected to produce between 385 and 1156tU per year.
