Todd River Resources Limited (ASX: TRT) has confirmed announce that following the identification of anomalous rare earth element (REE) values in end-of-hole sampling, re-assaying of the clay and saprolite zones has delivered thick intersections of strongly anomalous TREYO values from its 100% owned Pingrup Project in Western Australia.
Analytical results focusing on Ni-Cu-PGE mineralisation from aircore and reverse circulation (RC) drilling targeting previously identified magnetic targets (Greenfire and High Noon) within the Corrigin Tectonic Zone at the southwest Yilgarn Craton–Youanmi Terrane boundary were reported in May 2023.
Further analysis of the drilling data highlighted several areas that returned REE anomalism in the end of hole sample. A decision was taken to re-assay 10 holes across two traverses as an initial investigation into the end of hole anomalism with the initial re-assaying highlighting thick continuous enrichment of REE’s hosted in clay rich saprolite primarily over the ultramafic intrusion at Greenfire as well as thick slightly less enriched but still strongly anomalous zones over the High Noon intermediate intrusion.
At the Greenfire Prospect, re-assaying of six holes identified REE enriched clay-rich saprolite intervals up to 18m thick including 12m @ 1815ppm TREYO in hole PNAC0019 and 18m @ 1764ppm TREYO in hole PNAC0022 amongst other intersections.
At the High Noon Prospect, the intrusive rocks were predominantly granitic to intermediate in composition with the magnetic nature of the intermediate rocks explaining the magnetic high that was targeted. A well-developed clay horizon is developed in the regolith and hole PNAC0119 intersected 43m @ 1117ppm TREYO.
Further re-assaying will take place immediately with sections drilled to the north and south of the originally re-assayed lines a priority.
Following the recognition of strongly anomalous REE’s in the fresh rock sample from the end of several aircore holes, the results from the re-assaying of the clay rick saprolite are extremely encouraging,” Managing Director, Will Dix, said.
“It is very early days in terms of understanding the system and further information from the additional re- assaying of the remaining samples will go a long way to progressing this.
“As with the identification of any new potential mineralised system, work will also need to be done to characterise the material and an assessment on this work in terms of scope and timing is currently being considered.
“As mentioned in the previous ASX release in late May, our exploration efforts turn to Mt Hardy in the Northern Territory where we have recently received the AAPA certificate clearing the way for drilling to commence at the end of next month.
“We are excited to be back drilling at Mt Hardy for the first time since before the COVID-19 Pandemic and with the targets we have generated there, I am confident we will have some excellent results to share with the market once they are received.”
