This report describes exploration activities conducted over EPM27923 during the reporting period from 11 July 2022 to 22 August 2023. The title forms part of the South Palmer River Project. The Project area lies on a cratonic margin. The importance of major continental rifting for the generation of magmatic Cu Ni PGE deposits is well documented. Rhumb considers the area so be significantly underexplored, and believes that it has identified plugs, sills and dykes that are anomalous in platinum and palladium. Suggested targets are Triassic mafic ultramafic intrusives into Siluro Devonian Hodgkinson Formation sediments.
In the period leading up to the grant of title, and during the first year of tenure, Rhumb conducted desktop studies of relevant publicly available data to identify broad target areas on the title, collation and analysis of ASTER profiles over the title, reprocessing and enhancement of publicly available magnetic, radiometric and ground gravity data, and the generation of a regional 3D model. Collection of two stream sediment samples from publicly accessible road and track stream crossings. Anthill soil analysis. Vegetative material sampling and analysis. Collection and analysis of 31 soil samples using MMI to detect under cover anomalism. Electron microscope analysis of samples to analyse the origin and composition of PGE and petrographic analysis of one rock sample.
Rhumb has assessed that the interpretation of the limited geochemistry results and the geophysical mapping do not justify the retention of the tenement given the depth of base in the target areas. While the structures indicated may be significant and may host mafic ultramafic bodies, the depth to the base precludes accurate assessment other than by drilling the targets. The company believes that there are other more worthy targets in the North Palmer River Project area and have therefore relinquished the Title.
