Higher sales volume from mining business in FY25 & 1Q26 was mainly due to higher ore feed to KPS in line with higher production lines over period of time. In
addition, commenced operation of ONC in April 2024 also contributed to higher FY25 sales volume from mining business.
For FY25 HPAL sales volume, ONC (which reached full capacity in August 2024) is the main driver of growth in MHP sales. Combined sales from HPL & ONC
reached 130,551 tons of contained Ni, up 28% YoY. Meanwhile, 1Q26 HPAL sales volume reached 32,613 tons of contained Ni (up 8% YoY).
Significant growth of RKEF sales volume is due to KPS – phase 1 (which reached full capacity in March 2025), phase 2 (which reached full capacity in December
2025), and 2 production lines of phase 3 commenced operation in 1Q26. Overall FeNi sales volume was up by 49% YoY in FY25 and 22% YoY in 1Q26.
