Overview

The Mutooroo Ridge project (EL6230) is located 70km SW of Broken Hill. EL6230 was granted in August 2018 and relinquished in August 2021.

Mutooroo Ridge is a drill-ready project to test and extend historic oxide Cu intersections of 10m @ 1.57% Cu and 32 g/t Ag, and 5.2m @ 1.45% Cu and 25 g/t Ag that was obtained in the early 70’s, and 4m @ 1.27% Cu and 23.4 g/t Ag in the mid-2000’s. Mineralisation at Mutooroo Ridge bears characteristics of both VHMS and sediment-hosted Cu-Co deposits.

Exploration Program

Westrock’s exploration activities at Mutooroo Ridge consisted of:

• Historic exploration data compilation (completed in 2019).
• A 608 sample infill and extensional soil sampling program (completed).
• A 7-hole RC scout drilling program (completed in 2021).

Community Engagement

EL6230 is located entirely in the Mutooroo Pastoral Lease.

Since the granting of the exploration licence in August 2018, Westrock had regular engagements with the pastoral leaseholder and carried out low-impact field programs with consideration on grazing activities and the environment. Westrock is currently planning to carry out an RC drilling program where a more comprehensive community and environmental management plan will be implemented.

Westrock has also engaged and worked closely with the native title claimant of the project area. Members of the native title claimant took part in a heritage survey commissioned by Westrock in 2019. Westrock plans to offer training and employment opportunities to the native title claimant during the drilling program.
