Slide 9: Field work in the winter of 2025
Field work in the winter of 2025 • Bulk Sample – Graphite ore was mined to demonstrate the entire value chain from the pilot mine to the battery material process, creating materials for the batteries. • The work was carried out solely in the EV zone (northern zone). • Bulk samples – graphite ores we
Slide 10: Noise monitoring
Noise monitoring These stations were installed one week before work began in order to establish a baseline for noise levels. Geomechanical drilling: • From November 24, 2025, to January 16, 2026 • No work was carried out on weekends or from December 19 to January 5. • The blasting did not result in
Slide 11: Dust monitoring
Dust monitoring Quebec regulations: The average fine particulate over a 24-hour period cannot exceed 0.03 mg/m². To ensure compliance with this standard, three monitoring stations were installed near the bulk sampling pits in 2025. These stations operated on site from December 1 to 11. Bulk sampling

Slide 19: Project Opportunities
Project Opportunities • A total of up to 250 jobs will be created. • 160 operations employees would be needed during the entire production (30 years) • 250 construction workers would be needed during the construction phase. Lomiko will train local workers for equipment or factory operator positions.
Slide 20: Pre-feasibility Study Graphite Production

Slide 26: Waste Disposal Facilities (WDFs)
Waste Disposal Facilities (WDFs) WDF The mining waste will consist of filtered tailings (i.e., excess Outline water removed using filter presses and air drying) co- disposed with waste rock. Two WDFs were selected in areas with the least impact on aquatic environments (minimum 60 m away from major b
Slide 27: Noise berm
Noise berm Pit A noise barrier around the pits will be constructed from waste rock to minimize Noise barrier noise from the mining operations. Dimensions: 10 m high by 20-40 m wide. Purpose: • To prevent noise from spreading beyond the construction site. Concevoir les espaces de propagation du bruit
