Notes

1. CIM definitions were followed for MRE.
2. A minimum mining width of 2.0 m was applied in making the MRE constraint wireframes. These wireframes were generated using a preliminary MSO.
3. Density values for Nussir were estimated from density sample values or assigned default average values where insufficient samples occur nearby.
4. MRE constraint wireframes were generated for a cut-off grade of 0.30% Cu, related to potential underground mining.
5. Metal prices assumed for this MRE were US$4.20/lb Cu, US$27.00/Oz Ag and US$2,200/oz Au, which represent reasonable long-term consensus metal pricing.
6. Metallurgy recovery assumptions were 98% Cu, 80% Ag and 93% Au, which stem from SOS metallurgical testwork completed in 2022.
7. The cut-off grade of 0.30% Cu was derived from the price and recovery values above, as well as a smelter payability of 37.3% and an assumed total operating cost of $26.20/tonne of ore.
8. Rounding may result in apparent summation differences between tonnes, grades and metal content; not considered material.
9. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.
