LAX HA 25.1 Introduction The purpose of this chapter is to summarize the engagement and consultation conducted by IDM with Tsetsaut Skii km Lax Ha (TSKLH) and to conduct an assessment of the potential effects of the Project on TSKLH’s Aboriginal Interests in the Bitter Creek valley, as outlined in the Canadian Environmental Assessment Act, 2012 (CEAA 2012) and the Environmental Impact Statement Guidelines (the EIS Guidelines) issued for the Project by the Canadian Environmental Assessment Agency (the Agency). This chapter includes: • Background information and context regarding TSKLH; • An assessment of the potential effects on TSKLH’s Aboriginal Interests; • Proposed mitigation measures to avoid, mitigate, manage or otherwise address potential effects on TSKLH’s Aboriginal Interests; • An assessment of the potential residual effects on TSKLH’s Aboriginal Interests, after mitigation measure have been taken into consideration; and • A summary of any other matters of concern to TSKLH as expressed to IDM. The following valued components (VCs) and intermediate components (ICs) have informed this chapter: • Air Quality Effects Assessment (Chapter 7); • Noise Effects Assessment (Chapter 8); • Vegetation and Ecosystems Effects Assessment (Chapter 15); • Wildlife and Wildlife Habitat Effects Assessment (Chapter 16); • Fish and Fish Habitat Effects Assessment (Chapter 18); • Commercial, Recreational, and Aboriginal Fisheries, under the Economic Effects Assessment (Chapter 19); • Visual Quality, under the Social Effects Assessment (Chapter 20); and • Heritage Effects Assessment (Chapter 21). IDM MINING LTD. | RED MOUNTAIN UNDERGROUND GOLD PROJECT CHAPTER 25 | 1 ENVIRONMENTAL ASSESSMENT APPLICATION AND ENVIRONMENTAL IMPACT STATEMENT The assessment of potential effects on TSKLH’s Aboriginal Interests is based on a comparison between the predicted future conditions with the Project and the predicted
