Pardoo Nickel Project
Advanced nickel sulphide project featuring the Highway Deposit alongside regional exploration targets
Project Overview
The Pardoo Project lies close to existing infrastructure east of Port Hedland and covers tenure prospective for nickel, copper and platinum group elements. Its most advanced prospect is the Highway Deposit, located directly alongside the Great Northern Highway, making it uniquely positioned for future development.
The Highway Deposit is a shallow, disseminated nickel sulphide system with historic drill intersections including 95m @ 0.40% Ni and 14m @ 1.0% Ni, confirming the potential for a significant mineralised body. Importantly, elevated platinum group metals (PGMs) have also been reported, highlighting the polymetallic character of the system.
Beyond the Highway Deposit, regional targets across the broader Pardoo tenure remain largely underexplored. Geophysical surveys and historic drilling indicate additional zones of nickel sulphide prospectivity within favourable stratigraphy, but systematic modern exploration has not been undertaken across the majority of the ground.

Resource Development
Work to date has focused on bringing the deposit up to JORC 2012 standards and identifying extensions along strike and at depth. Snowden Optiro previously estimated a resource for the Highway Ni-Cu-Co deposit of 50Mt at 0.30% Ni, 0.13% Cu and 0.03% Co using a 0.1% Ni minimum cut-off grade in 2010, though this requires upgrading to current standards.
Recent drilling programs have included 34 RC holes for a total of 5,865m, with ongoing geological and mineralogical work supporting the resource estimate and future metallurgical test work.
Future Programs
This provides Mantle with the opportunity to test high-priority targets in parallel with advancing the Highway resource. Geophysical work continues to help target more high-grade nickel sulphide zones across the broader tenure.
With a combination of an established shallow deposit and a suite of underexplored regional prospects, Pardoo represents both a near-term development asset and a longer-term growth opportunity within Mantle's portfolio.
