2023 Sustainability Report Highlights

We continued to build the capacity of our organization to achieve our business and sustainability goals. Some of our highlights from 2023 include:

  • Making progress on The Copper Mark: Mantos Blancos and Mantoverde were awarded The Copper Mark.

  • Implementing our Sustainable Development Strategy: We launched new cross-site and cross-functional working groups for our Sustainable Development strategic priorities of Climate, Water, Tailings, Biodiversity, and Communities.

  • Increasing renewable energy electricity purchases: We secured 100% coverage of our electricity use at Mantos Blancos through renewable energy certificates.

  • Enhancing sustainability data disclosures: For the first time, we are publishing a comprehensive sustainability performance data book which contains four years of data for relevant material topics for Capstone as a whole and by site. We are also reporting both market-based and location-based greenhouse gas ("GHG") emissions for the first time.

Some 2022-2023 data trends include:

  • Total water withdrawal increased 3% to 19 million cubic metres while the percentage of non-freshwater (other water) withdrawals stayed constant at 22%.

  • Total energy use rose by 2% due to increases in fuel use (4%) mainly driven by fuel for capital projects. Electricity use was down 2%. Total market-based GHG emissions decreased by 3% due to the growing share of renewable energy sources in both the Chile and Arizona grids and the purchase of renewable energy certificates for Mantos Blancos.

  • Per 200,000 hours in 2023, our Lost Time Injury Frequency Rate (LTIFR) was 0.18 (up from 0.15 in 2022) and our Total Reportable Injury Frequency Rate (TRIFR) was 0.35 (up from 0.21 in 2022). While incident rates were up for the year, we saw an improvement in the last quarter of 2023 as sites focused on incident review and communication as well as monitoring and detection on the ground by supervisors and leadership.

  • Capstone’s combined workforce grew slightly by 1% to 8,520 (8,425 in 2022) with a 9% increase in number of employees and a 3% decrease in contractors. The proportion of women employees increased from 8% to 9%. Global employee new hire rate (21%) and turnover rate (13%) remained relatively constant which is an indication of a relatively stable employee workforce.
