Mineral Resources

Mt Edwards Project Mineral Resources

The Mt Edwards Project represents one of the largest known unmined nickel sulphide Mineral Resource in Australia, currently comprising 13.04Mt at 1.45% Ni for 188,160 nickel tonnes. Importantly it is in a renowned nickel region hosting a number of significant producing mines and with downstream processing infrastructure nearby. The BHP Kambalda concentrator is located approximately 40km to the north-east of the Mt Edwards Project. However, the attributes and close proximity of the deposits also presents the opportunity for a standalone nickel concentrator at the Project.

Notes:

1. Above a 1% Ni cut-off, except Widgie 3, Gillett, Widgie Townsite and Armstrong, reported at 0.7% Ni cut-off

2. 0.85% Li₂O cut-off
3. Reporting 0.30% Li₂O cut-off grade above 310mRL, 0.5% Li₂O cut-off grade below 310mRL
4. Tonnes and grades have been rounded to reflect the relative uncertainty of the estimate
   

Butchers Creek Gold Project Mineral Resources

The global mineral resource for Butchers Creek is 5.6Mt at 2.0g/t Au for 357,000oz of gold comprising  the Butchers Creek and Golden Crown deposits. Inclusive of 139,000oz of higher confidence indicated resource at Butchers Creek.

MEI published the maiden Mineral Resource Estimate (MRE) for Butchers Creek in 2021 whilst restating NST’s 2007 MRE for Golden Crown in accordance with the 2012 JORC code. The Golden Crown MRE combines the Golden Crown and Faugh-a-Ballagh prospects due to their close proximity and similar geological features. Both Butchers Creek and Golden Crown deposits have been reported at a 0.8g/t Au cut-off.

(For full details please refer to ASX:MEI announcement “Thick Gold Mineralised Zones at Butchers Creek” Released 26 October 2021).
