Todd River Resources uncovers thick TREYO intersections at Pingrup Project in WA

Australian explorer Todd River Resources (ASX:TRT) has uncovered thick intersections of ‘strongly anomalous’ Total Rare Earth and Yttrium Oxide (TREYO) values at its Pingrup Project in Western Australia.

The company reports these TREYO values were revealed through the re-assaying of 10 holes across 2 traverses with clay and saprolite zones at the project.

The news comes after Todd River on May 25 reported analytical results focusing on nickel-copper-platinum group element (PGE) mineralisation from aircore (AC) and reverse circulation (RC) drilling at the southwest Yilgarn Craton-Youanmi Terrane boundary.

Further analysis of the drilling data highlighted several areas that returned REE anomalism in the end-of-hole sample. The company says a decision was taken to re-assay 10 holes across 2 traverses as an initial investigation into the end-of-hole anomalism.

This work highlighted a thick continuous enrichment of REEs hosted in clay-rich saprolite primarily over the ultramafic intrusions at the Greenfire prospect, as well as thick, slightly less-enriched but still ‘strongly anomalous’ zones over the High Noon intermediate intrusion.

Results recorded at Greenfire include PNAC0019 with 12m @ 1,815 parts per million (ppm) TREYO; and PNAC0022 with 18m @ 1,764ppm TREYO.

At the High Noon prospect, Todd River Resources says intrusive rocks were predominantly granitic-to-intermediate in composition, with the magnetic nature of the intermediate rocks explaining the magnetic high that was targeted. The company says a ‘well-developed’ clay horizon is developed in the regolith, noting PNAC0119 intersected 43m @ 1,117ppm TREYO.

Todd River Resources reports further re-assaying will take place immediately, with sections drilled to the north and south of the originally re-assayed lines a priority.

Commenting on the results, Todd River Resources Managing Director Will Dix says: “Following the recognition of strongly anomalous REEs in the fresh rock sample from the end of several aircore holes, the results from the re-assaying of the clay-rich saprolite are extremely encouraging.

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.

We are excited to be back drilling at Mt Hardy for the first time since before the COVID-19 pandemic”

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 the 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.”

Todd River Resources is an Australian base and precious metals explorer focused on its Mt Hardy Project in the Northern Territory, along with the Berkshire Valley and Pingrup projects in Western Australia.

The Pingrup Project covers about 240km-square within the Corrigin Tectonic Zone, about 300km southeast of Perth. The project area features 12 magnetic features, with historical work confined to just 3 of them.
