WA Cu-Au / Mo
Royale
Buxton’s Royale Project is a large, 100% owned greenfields Cu-Au/Mo play in the Paterson Region of Western Australia where several recent world-class Cu-Au discoveries have been made by companies undertaking systematic, modern grassroots exploration methods.
Within the Royale Project area, Buxton’s review of open file geochemistry highlighted a belt of felsic intrusive rocks which have signatures indicating prospectivity for magmatic/hydrothermal Cu-Au / Mo mineral systems (e.g. porphyry style).
This belt trends toward a regional magnetic high / gravity low which is most likely mapping a large volume, high level magmatic pluton at 5-10 km depth. The area above this pluton is where potentially economic Cu-Au/Mo mineralisation is most likely to be found.
The basement rocks in this area are obscured by a veneer of transported sediments, with around 50% of the Project area having less than 50 metres of cover.
A number of reconnaissance diamond holes were drilled within and surrounding the Project area (RUD prefix). Geochemical data from these holes, particularly RUD0003, show Cu propectivity patterns to GSWA / GA rock chip samples near the Copper Hills skarn-style base & precious metal occurrence.

Detailed magnetics over the principal target highlights targets for direct drill testing.
Tornado imagery of core from RUD0003. In addition to strong (localised) copper mineralisation, there is clear evidence of a potassic alteration overprint and the diversity of weakly deformed porphyritic rock types indicates that a high crustal level has been preserved at shallow depths.
GA TEMPEST survey flown in 2007 at 2 km line spacing with Depth to Basement interpretation indicates a large portion (~50%) of the tenure is under 50m of cover. The axis of the major paleodrainage features are indicated in thick red dashed lines.
