Resource Base applies for more ground around Mitre Hill rare earths project
新的许可证将使 Mitre Hill 项目的占地面积增加到 6,001 平方公里。
Exploration junior Resource Base (ASX: RBX) has applied for another five exploration licences prospective for clay-hosted rare earth elements at the Mitre Hill project in western Victoria.
The new licences cover 1,171 square kilometres and boost the project’s total footprint to 6,001sq km.
Upon granting of all tenements, Resource Base will have the largest land position in the southern margin of the Murray Basin, which is believed to be an emerging globally-significant clay hosted REE precinct.
Geological modelling indicates the new tenements could be prospective for clay-hosted REE, which will add significantly to the scale of the Mitre Hill project.
Resource Base has also submitted one exploration licence application in Victoria, totalling 495sq km of the Black Range project, located in the the Mount Stavely Volcanic Complex known to be the state’s premier porphyry and VHMS (volcanogenic massive sulphide) target district.
In July, the company intersected gold-silver-zinc sulphide mineralisation at the project’s Callisto prospect, located 2km from main Eclipse-Nebula target.
Current tenements
Resource Base’s Mitre Hill project currently includes 27 tenements comprising 22 applications and four granted licences along the southern margin of the Murray Basin in Victoria, and one granted tenement in South Australia.
Exploration of these areas will test for the presence of Murray Basin stratigraphy known to host REE and will aim to expand the mineralisation model in the region.
The area has relatively been underexplored and little is known of the minimal basement economic potential.
Similar granitic rocks host known tin and tungsten mineralisation elsewhere in Victoria and Tasmania.
Step-out drilling
Earlier this month, Resource Base completed an initial step-out drilling campaign at Mitre Hill, comprising 125 holes for 1,348m targeting areas where higher-grade mineralisation had previously been discovered.
Initial visual results indicated a widespread occurrence of REE-prospective clay horizons across the area.
The company said drilling would continue to test across the extent of the tenement and onto new ground to the north as winter rains clear and ground conditions improve.
