The fair value of these shares on the issue date was $15.05 which resulted in a loss in the extinguishment of liabilities of $326,000 o 400,000 shares issued on 2 February 2026.

Due to the highly specialised nature of the inventory and the fact that there is no observable market for ultra-high-grade copper powder and significant variations in pricing based on known market transactions, the Company has determined the cost of the inventory based on the fair value of the shares issued to the seller. Consequently, the cost of the ultra-high-grade copper powder is $15,800,000 being 2,000,000 shares at $7.90 per share, being the fair value of the shares as at the date of acquisition (note 6) ◾ 14,500,000 shares issued upon the stage 2 acquisition of Tanbreez (note 31) ◾ 150,262 shares issued upon the 70% acquisition of 60 North Greenland ApS acquisition (note 32) ◾ 3,337,709 shares upon the exercise of options comprising o 3,315,000 shares upon the exercise of 3,315,000 unlisted warrants ($7.00 each expiring 7 February 2029) o 12,709 shares upon the exercise of 12,709 listed warrants ($11.50 each expiring 27 February 2029) o 10,000 shares upon the exercise of 10,000 unlisted warrants ($7.00 each expiring 6 October 2031) ◾ 873,942 shares upon the exercise of options utilising the cashless facility comprising: o 38,468 shares issued upon the exercise of 50,100 warrants ($7.00 each expiring 7 February 2029) o 835,474 shares issued upon the exercise of 1,000,000 warrants ($5.00 each expiring 18 June 2029)
