澳大利亚矿业公司Dateline Resources Limited (ASX: DTR, OTCQB: DTREF, FSE: YE1) 宣布其位于美国加州的重稀土项目Music Valley获得重大扩张。 该公司通过确认向美国土地管理局(BLM)提交了969项申请并获得批准，成功将Music Valley Heavy Rare Earth Project的面积扩大至19,380英亩。此次扩张使整个项目区域达到1,026个矿权，总计20,520英亩，涵盖了近9公里具有前景的Pinto片麻岩单元。
Dateline Resources首席执行官Stephen Baghdadi表示：“Music Valley为我们提供了接触一个地质单元的机会，该单元早在70多年前就被美国地质调查局(USGS)记录为含有重稀土矿物。我们的策略是在利用现代勘探技术的基础上，建立在这个历史工作的基础上。” 目前，航空磁测和放射性测量工作已完成约65%，公司的稀土专家已开始进行地表测绘和取样工作。初步化验结果预计将在本季度晚些时候公布。 Music Valley项目位于加州河滨县和圣贝纳迪诺县，靠近莫哈韦沙漠构造过渡区。
该地区的Pinto片麻岩被确认为早前寒武纪高级变质复合体，含有潜在的稀土矿物，如独居石、褐帘石和磷钇矿。 除了Music Valley项目外，Dateline还拥有加州的Colosseum金-稀土项目和Argos锶项目。Colosseum项目拥有经JORC 2012标准认证的27.1Mt @ 1.26g/t Au资源量，相当于110万盎司黄金，且矿化在深部仍有延伸空间。Argos项目则被认为是美国最大、品位最高的天青石矿床之一。 随着Music Valley项目的扩张和勘探工作的推进，Dateline正逐步构建其在北美稀土领域的战略布局。
