Yarawindah Brook Project

Yarawindah location map

The Yarawindah Brook Project is an early stage, underexplored Nickel-Copper-Cobalt project.

Yarawindah Brook is located 130km northeast of Perth, in agricultural land near the township of New Norcia. The Project has had only limited nickel, copper and cobalt exploration despite a favourable regional setting, prospective geology and near-surface occurrences of nickel and copper. Historic exploration has focussed primarily on a small platinum and palladium (PGE’s) resource which the Company views as a “path-finder” anomaly for massive nickel-copper-cobalt sulphides. 

Exploration for nickel and copper has been sporadic, however the most recent drilling in 2007 targeting surface EM anomalies, returned encouraging results from hole YWRC0083 including 7m @ 1.30% Ni, 0.22% Cu, 0.06% Co and 432ppb Pd from 74m. Despite the promising result no further follow-up drilling was conducted due to budget limitations of the previous operator during the exploration downturn post-GFC.

Cassini completed an airborne electromagnetic survey (AEM) over the project in early 2018, identifying numerous conductors worthy of further investigation. A surface fixed loop electromagnetic (FLEM) survey has also been completed over several of the higher priority AEM anomalies in order to confirm and better constrain the conductors prior to drilling. The FLEM has reinforced the XC05 and XC06 anomalies as priority targets along with down-plunge testing of YWRC083 (Figure 1).

The Company’s maiden drill program got underway in December 2019 targeting two separate prospect areas, the XC05 conductor and the AN01-AN02 conductors. The program consists of approximately 1,000m of diamond drilling and is due to conclude in January 2020.

Cassini views the Project as an excellent opportunity to apply its geological expertise and learnings in nickel-copper systems from the West Musgrave Project to an apparently similar mineralised system with only limited modern exploration. Further, the project is conveniently located adjacent to roads and power, providing development advantages if exploration proves successful. 

Recognising the prospectivity of the region, Cassini has added additional tenements along strike, taking the total land position to 146km2.

The project provides Cassini with further exposure to nickel, copper and cobalt, three critical components of advanced technology and a decarbonised future.
