Warintza

Primary Infrastructure: Natural Cost Advantage

• 268km² property, 40km north of Mirador mine (US$1.4B / 20 Mtpa), Adjacent to San Carlos-Panantza (1.1 Bt combined)
• Access road to nearby highway connecting Pacific ports, transmission lines, airport, skilled labour, fresh water
• Access to grid power (hydroelectric), adjacent Santiago G8 development (US$4B / 3,600MW)

Two-Pronged Strategy: Growth and Discovery

• In-Pit Inferred Resource: 124 Mt @ 0.70% CuEq¹ (0.56% Cu, 0.03% Mo, 0.1 g/t Au) based on minimal historical drilling to 200m on discovery outcrop (2000-2001)
• 40km drilling for Resource Update at Warintza Central in H1/21 (1km x 1km x 0.5km volume at 100m spacing)
• Significant new discovery at Warintza West (SLSW-01: 798m of 0.31% CuEq¹, incl. 260m of 0.42% CuEq¹ from 32m depth) outside anomaly
• Maiden/discovery drilling at Warintza East and Warintza South in H1/21; Drilling regional targets in H2/21

Undrilled Regional Targets

• Three large-scale, gold anomalies from surface sampling at Warintza
• >0.5 g/t gold-in-soils across broad area, overlapping copper anomaly at Caya
• Geophysical survey identified additional blind targets to test
• Two additional gold anomalies at Clemente

Responsible Mining – Inclusive Approach

Community Involvement is Key to Warintza Success, Resilience

• Innovative approach: commitment to transparency, education and inclusion
• Government and community understanding of impacts and benefits of project
• Community involvement at each step, enhanced with capacity-building program

The Warintza Success Story

• World class discovery by David Lowell in 2000, sat largely dormant since 2001 due to a breakdown in social acceptance from local communities
• Extensive dialogue led to understanding root causes of conflict, resolution of underlying issues mid-2019; instituted an informed, innovative CSR program
• Government-Sponsored Prior Consultation process with community stakeholders and signed Impacts & Benefits Agreement in 2020

The Warintza Model

• Participatory mining model that promotes dialogue between State – Company – Community based on transparency, collaboration, and trust contributing towards the sustainable socio-economic development of the communities and project
• The Warintza Model, through the Strategic Alliance and its Board of Directors, contributes to the local development of the Shuar Nations in tandem with the project’s advancement, including investment in health and education, support for legal mining, environmental stewardship, promotion of entrepreneurship, gender equality, labor and human rights, security, and prospection and exploration activities
