Non-recurring items in 2018 relate to abnormal costs at Porgera as a result of the February 2018 earthquake in Papua New Guinea. These costs are not indicative of our cost of production and have been excluded from the calculation of cash costs.
Other adjustments for the three and nine month periods ended September 30, 2018 include adding the cost of treatment and refining charges of $nil and $1 million, respectively, (2017: $nil and $1 million, respectively) and the removal of cash costs andby-product credits associated with our Pierina mine, which is mining incidental ounces as it enters closure, of $18 million and $60 million, respectively (2017: $25 million and $73 million, respectively).
4 | Non-controlling interests (Pueblo Viejo and Acacia) |
Non-controlling interests includenon-controlling interests related to gold production of $121 million and $339 million, respectively, for the three and nine month periods ended September 30, 2018 (2017: $103 million and $317 million, respectively). Refer to Note 5 to the Financial Statements for further information.
5 | Exploration and evaluation costs |
Exploration, evaluation and project expenses are presented as minesite sustaining if it supports current mine operations and project if it relates to future projects. Refer to page 32 of Barrick’s third quarter MD&A.
Capital expenditures are related to our gold sites only and are presented on a 100% accrued basis. They are split between minesite sustaining and project capital expenditures. Project capital expenditures are distinct projects designed to increase the net present value of the mine and are not related to current production. Significant projects in the current year are stripping at Cortez Crossroads, the Range Front declines, the Goldrush exploration declines, the Deep South Expansion, and construction of the third shaft at Turquoise Ridge. Refer to page 31 of Barrick’s third quarter MD&A.
7 | Rehabilitation—accretion and amortization |
Includes depreciation on the assets related to rehabilitation provisions of our gold operations and accretion on the rehabilitation provision of our gold operations, split between operating andnon-operating sites.
8 | Non-controlling interest and copper operations |
Removes general & administrative costs related tonon-controlling interests and copper based on a percentage allocation of revenue. Also removes exploration, evaluation and project expenses, rehabilitation costs and capital expenditures incurred by our copper sites and thenon-controlling interest of our Acacia and Pueblo Viejo operating segments and South Arturo. Figures remove the impact of Pierina. The impact is summarized as the following:

9 | Ounces sold - equity basis |
Figures remove the impact of Pierina as the mine is currently going through closure.
10 | Cost of sales per ounce |
Figures remove the cost of sales impact of Pierina of $23 million and $84 million, respectively, for the three and nine month periods ended September 30, 2018 (2017: $38 million and $119 million, respectively), as the mine is currently going through closure. Cost of sales per ounce excludesnon-controlling interest related to gold production. Cost of sales applicable to gold per ounce is calculated using cost of sales on an attributable basis (removing thenon-controlling interest of 40% Pueblo Viejo, 36.1% Acacia and 40% South Arturo from cost of sales), divided by attributable gold ounces.
Cost of sales per ounce, cash costs per ounce,all-in sustaining costs per ounce andall-in costs per ounce may not calculate based on amounts presented in this table due to rounding.
12 | Co-product costs per ounce |
Cash costs per ounce,all-in sustaining costs per ounce andall-in costs per ounce presented on aco-product basis removes the impact ofby-product credits of our gold production (net ofnon-controlling interest) calculated as:
| | | | | | | | | | | | | | | | |
