(1) CO,
(2) NOx (excluding N2O),

Energy Management (SASB 130)
EM-MM-130a.1 (1) Total energy consumed
(2) percentage grid electricity
(3) percentage renewable
Page 61-63
Water Management (SASB 140)
EM-MM-140a.1. (1) Total fresh water withdrawn
(2) total fresh water consumed,
percentage of each in regions with High or Extremely High Baseline Water Stress
Marigold is our only mine located in an area with high baseline water stress according to the World Resources Institute’s (WRI) Water Risk Atlas tool, Aqueduct. Water we abstract in areas with high baseline water stress accounts for 23% of our total water withdrawal.
EM-MM-140a.2. Number of incidents of non-compliance associated with water quality permits, standards, and regulations Zero
Waste & Hazardous Materials Management (SASB 150)
EM-MM-150a.1. Total weight of tailings waste, percentage recycled Page 68
EM-150a.2 Total weight of mineral processing waste, percentage recycled N/A
EM-150a.3. Number of tailings impoundments, broken down by MSHA hazard potential SSR mining owns three active and one inactive tailings storage facility .
Based on the Canadian Dam Association Consequence Classification Ratings for Dams, all three active tailings storage facility are categorized as High Hazard potential, and the inactive facility is categorized as low.

Biodiversity

Biodiversity Impacts (SASB 160)
EM-MM-160a.1 Description of environmental management policies and practices for active sites Page 59
EM-MM-160a.2 Percentage of mine sites where acid rock drainage is: (1) predicted to occur,
(2) actively mitigated, and
(3) under treatment or remediation
At Çöpler, potentially acid-forming materials are managed in line with local Turkish regulations, industrial best practices and the IFC Performance Standards.
At Puna, the waste rock is expected to be largely non-acid generating, with a small portion that may be weakly acid generating under certain oxidizing conditions. The waste rock with potential for acid production will be placed so as to have any drainage report to the pit and avoid
introduction to the environment.
Acid Rock drainage is not expected to occur at our other sites.

People

Labour Relations (SASB 310)
EM-MM-310a.1. Percentage of active workforce covered under collective bargaining agreements, broken down by U.S. and foreign employees 38% of our direct employees are union members and are covered by collective bargaining agreements in place.

(2) Zero fatalities
(3) Not disclosed
(4) a) 22
b) 5
Security, Human Rights & Rights of Indigenous Peoples (SASB 210)
EM-MM-210a.1. Percentage of (1) proved and (2) probable reserves in or near areas of conflict Our Çöpler Mine is located in an area classified as “Level 3 – Violent crisis” on the index from the Heidelberg Institute for International Conflict Research. We use the Heidelberg index as it provides regional-level information and is recommended by the World Gold Council Conflict- Free Gold Standard®.
EM-MM-210a.2 Percentage of (1) proved and (2) probable reserves in or near indigenous land The Seabee Gold Operations is located adjacent to the Lac La Ronge Indian Band and the Peter Ballantyne Cree First Nation territories. No formal agreements are in place with Indigenous Peoples’ communities.
