All-in Costs and Margins


First Half All-in Cost Breakdown


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 new production facility for the existing operations where these projects are expected to materially increase production in future.


The all-in costs per ounce in 1H2021 were slightly higher than the all-in costs in 1H2020, mainly due to the increase in royalty and tribute expenses (for reasons presented in the operating expenses analysis above).
