Growing the Resource

Cummins Range unique geology points to high grade potential

• Carbonatite intrusive complex with REE mineralisation controlled by hydrothermal fluids
• Historic drilling mostly orientated in the wrong direction
• Recognition of high grade main fault / breccia zone for first time provides for high grade depth potential
• Possibility of multiple structures

5,272m drill program complete

• 2,271m of RC Drilling complete
• 3,001m of Diamond drilling first time since 1982

Potential to grow the resources significantly

Primary Mineralisation Confirmed

Initial Diamond Results

First batch of assays confirm true width of the Main Fault to be >40m and identify new mineralised position, highlighting the deposit's exceptional growth potential

• CRX0063 intersects multiple mineralised zones, including:
  • Main Fault 41m at 2.4% TREO and 0.51% Nb2O5 from 57m, including:
  • 10m 4.1% TREO and 0.75% Nb2O5
• CDX0011 iterecets high grade primary mimerlisation including
  • 22m at 3.1% TREO and 0.2% Nb2O5
  • Inc; 3m at 10.6%TREO
• CDX0012 and CDX0016 Intersects significant primary mineralisation – open down dip

Multiple stacked lodes emerging

Initial Diamond Results

Proof of High Grade primary rare earths and niobium mineralisation in CDX007

• Primary Zone – 34.6m at 1.3% TREO and 0.4% Nb2O5 including 3.6m at 2.5% TREO and 0.7% Nb2O5

Strong economic drivers in the primary zone including

• Good NdPr content up to 24% comparable to Mt Weld
• Strong Niobium by-product potential 0.4% average and high grade 0.7%

Study Work

• Recent Exciting Drilling results – potential change in Scope • Recently appointed GM Projects Mr James Durrant • Scoping Study scheduled for completion March Quarter 2022
