Double Materiality Assessment Results – Topic Placement Overview

Each topic below is positioned on a chart that measures both its importance to Alamos Gold’s financial performance (horizontal axis) and its significance for social or environmental impact (vertical axis). The chart is divided into four quadrants:

Double Material (Top Right, Green): Topics assessed above the threshold for both financial materiality (i.e., potential to affect Alamos’ financial performance) and impact materiality (i.e., Alamos’ potential to cause significant social or environmental impacts).
Impact Material, Financially Immaterial (Top Left, Orange): Topics assessed above the threshold for impact materiality, but below the threshold for financial materiality.
Financially Material, Impact Immaterial (Bottom Right, Yellow): Topics assessed above the threshold for financial materiality, but below the threshold for impact materiality.
Double Immaterial (Bottom Left, Red, not shown): Topics assessed below the threshold for both financial and impact materiality. These topics have been excluded from the visual representation.

Topic-by-Topic Placement:

Safe and Healthy Working Conditions:
Placed firmly in the top right quadrant, this topic is highly significant for both financial performance and social/environmental impact.
Equity, Diversity, Inclusion:
Found in the top left quadrant, this topic is especially important for its impact on people and society, but is just below the threshold for financial significance.
Human Rights in the Workplace:
Also in the top left quadrant, this topic is recognized for its strong impact on society, though it is less directly tied to financial outcomes.
Public Safety and Emergency Services:
Located in the top left quadrant, this topic is very important for its societal impact, but less so for financial considerations.
Human Rights and Security in Host Communities:
This topic is roughly 3/5 the way up the chart on the Impact Materiality scale and is right between the Impact Material, Financially Immaterial quadrant and the Double Material quadrant.
Community Investment and Community Relations:
In the top right quadrant, this topic is a priority for both financial and impact materiality.
Geopolitical Interests:
Bottom right quadrant, this topic is the highest placed topic for financial materiality, but also by far the lowest for impact materiality.
Indigenous Relations:
In the top right quadrant, this topic is important for both financial and impact materiality.
Business Practices and Ethics:
Also in the top right quadrant, this topic is significant for both financial and impact materiality.
Cybersecurity and Data Protection:
In the top right quadrant, this topic is important for both financial and impact materiality.
Process Residuals and Other Wastes:
Top right quadrant, showing high importance for both financial and impact materiality.
Biodiversity and Land Use:
This topic sits near the very top of the chart, making it extremely important for impact materiality, and is right between the Impact Material, Financially Immaterial quadrant and the Double Material quadrant.
Water Availability:
Top right quadrant, important for both financial and impact materiality.
Water Management:
Top right quadrant, with very high importance for impact and a strong impact on financial materiality.
Air Quality and Pollutants:
Top left quadrant, this topic is highly significant for its impact on society and the environment, but less so for financial performance.
Climate Change and Climate Mitigation:
Top right quadrant, this topic is a priority for both financial and impact reasons.
Energy Management:
Bottom right quadrant, this topic is important for financial materiality, but second lowest for impact materiality.
