Perseus Mining has updated its greenhouse gas (GHG) emission factors and extended its reporting boundaries to include all sources under operational control, enhancing its GHG reporting accuracy and transparency. The company measures its GHG emissions in accordance with the Greenhouse Gas Protocol, applying an operational control boundary.
Material actions and disclosures
Scope 1 and Scope 2 emissions are reported for the Group, covering the three operational mine sites (Yaouré, Edikan, and Sissingué), the Nyanzaga Gold Project, the Meyas Sand Project in Sudan (prior to divestment), corporate offices, and exploration activities. There are no associates, joint ventures, or unconsolidated subsidiaries with material Scope 1 or Scope 2 emissions to report separately. Scope 2 emissions are reported on a location-based basis.
In FY26, Perseus reviewed its GHG inventory and extended its emissions boundary to capture all sources under its operational control. This added corporate offices, exploration activities, and the Sudan operations prior to divestment, ensuring the FY26 inventory reflects the operational control approach under the GHG Protocol.
Perseus also updated its emission factors and energy-content factors for FY26 to reflect the country-specific data for its operating jurisdictions, drawing on credible international sources to ensure the factors used are current and fit for purpose. The changes are outlined in Appendix 1: Basis of Preparation.
Perseus’s capacity to adjust its strategy and business model in response to the effects identified in the Climate Scenario Analysis is supported by financial resources and a self-funded position and project-initiated capital allocation approach, preserving flexibility to respond to climate-related investment needs without requiring pre-committed capital.
Perseus acknowledges that under the Net Zero 2050 scenario, current adaptive measures may not be sufficient to fully offset operating cost exposure from carbon pricing and energy price escalation, and that maintaining financial resilience under a stronger Transition pathway may require more substantive action. The company will continue to monitor this position and reassess as conditions evolve.
