Chase Mining Corporation Limited Applies Three Uncontested 100 Sub Block Exploration Permits (Epmas) in Grazing Country in the Boulia Duchess Area of Northwest Queensland
Chase Mining Corporation Limited announced that has applied for three uncontested 100 sub block Exploration Permits (EPMAs) in grazing country in the Boulia Duchess area of northwest Queensland. Native Title and Heritage agreements are required prior to grant, so timing is unknown. Two of the adjoining EPM applications comprise the Boulia Project and the other the Digby Peaks Project. The Boulia project area is comprised of two EPM applications Canary (EPMA 28251) and Prickly Bush (EPMA 28253). Previous exploration by Jacaranda Minerals Ltd. (EPMs 15234, 15235, and 15236, and in CRs 67692, 67931, and 67700) was mainly for uranium. Later, Hartz Rare Earths Pty Ltd. (EPMs 25158, 25159, 25160 and 25295 and in CRs 090037,090038, 090039, and 090040) conducted wide spaced stream sediment sampling that identified catchments strongly anomalous in rare earths and less so for copper nickel cobalt lead and zinc. The anomalous catchments when contoured according to metal contents, reveal a distribution along northwest striking shear structures in the Cretaceous age sediments of the Toolebuc and Allaru formations. The maximum anomalism (732 ppm Total Rare Earths, including 190 ppm Neodymium) is from a large catchment within the CML applications. This anomalism has not been closed off to the northwest, where there are magnetic structures of the same orientation, which are possibly carbonatite dykes and the source of the surface concentrations of rare earth mineralisation. As the host sediments are Cretaceous in age, the shear zones, alteration, and mineralisation are very young, most likely Tertiary, and appears to be controlled by dilation faults splaying from the Burke River fault zone. If correct this represents a new age and style of rare earths deposition in Australia. Digby Peaks Project: The Digby Peaks project is comprised of a single 100 sub block EPM application (EPMA 28256). CML selected the project area on the basis of the known but poorly defined rare earths in the general locality outside the application, but more particularly because of the similar geochemistry and geology to the new Boulia Project area further south along the Burke River fault zone as described above.

CML selected the project area on the basis of the known but poorly defined rare earths in the general locality outside the application, but more particularly because of the similar geochemistry and geology to the new Boulia Project area further south along the Burke River fault zone. The Digby Peaks mineral occurrence was sparsely sampled by CRA in 1977 under EPM 1605 and reported in CR6056. According to the Qld Government geochemical database, CRA located drainages and rocks anomalous in nickel copper cobalt lead and zinc. Rock samples from sheared brecciated carbonate sediments assayed up to 0.48% nickel. This unusual geochemical signature is similar to the Boulia Project's. Digby Peaks lies along the western margin of the Tertiary age Burke River fault, as does the Boulia Project. The CML concept is that the Digby Peaks base metal occurrence, like the Boulia Project, is also a focus for shear hosted rare earths mineralisation.
