All-in Costs and Margins
Latest Quarter 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. The decrease of gold ounces sold resulted in higher cost per gold ounce sold as fixed costs portion remains constant. These costs may vary from quarter to quarter, depending on the 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 the new operations and costs related to construction of the new production facility for the existing operations where these projects will materially increase production in future.
The all-in costs of US$1,236 per ounce in 4Q 2017 were comparable to the all-in costs of US$1,228 per ounce in 4Q 2016.
Overall, the all-in costs of US$1,367 per ounce in FY2017 was approximately 67% higher than the all-in costs of US$819 per ounce in FY2016. This was mainly due to the significantly lower production and sales volume of fine gold arising from lower ore grades which had plagued production in 2017, as well as costs due to the construction of a new CIL plant.
