All in Costs Table

¹ Adjusted operating costs include production costs such as mining production and maintenance costs, royalties, and operating costs such as storage, net of by-product credits. These costs may vary depending on seasonal or cyclical factors, including among others, rainy season and grade of gold extracted from the ore.

² All-in sustaining costs include adjusted operating costs and sustaining capital expenditure, corporate general and administrative expenses, exploration expense, reflecting the full cost of gold production from current operations.

³ Include all-in sustaining costs and non-sustaining costs. Non-sustaining costs are costs incurred for new operations and costs related to construction of the additional production facility for the existing operations where these projects are expected to materially increase production in future.

All-in costs per ounce in 1H2024 were 6.4% lower, as compared to 1H2023. This was mainly due to economies of scale arising from the increased production and sale volume of fine gold. The increase in non-sustaining capital exploration was due to higher exploration drilling activities carried out on the producing mines.
