Freeport talks Yandera copper optimization study

Executive Summary

• Freeport Resources released a two‑phase optimization and value‑add study for its Yandera copper‑gold‑molybdenum project, outlining a high‑grade, lower‑throughput development pathway.
• Updated commodity price assumptions (copper $5.49/lb, molybdenum $30.29/lb, gold $3,348/oz) significantly improve the historic post‑tax NPV from $1,038 M to an undisclosed higher value.
• The study identifies opportunities for improved grade control, ore‑sorting, and blended financing (including DFI debt) to reduce capex ($930 M) and enhance project economics.

Key Details

• Study Scope: Conducted by Practara Pty. Ltd.; Phase 1 evaluated selective mining at reduced throughput; Phase 2 produced a concept study with open‑pit optimization, higher cut‑off (0.40% Cu), and detailed mine scheduling.
• Historical Baseline: 2017 prefeasibility NPV (10% discount) $1,038 M based on copper $3.35/lb, molybdenum $10.00/lb, gold $1,400/oz.
• Current Price Assumptions: Copper $5.49/lb, molybdenum $30.29/lb, gold $3,348/oz – driving upside in project valuation.
• Capital Expenditure: Original capex estimate $930 M; study models lower upfront capital for a phased, high‑grade operation.
• Potential Financing Structures: Optimized debt structuring and blended finance (commercial debt + concessional DFI funding) to reduce weighted average cost of capital.
• Exploration & Development Spend: Over $200 M U.S. already invested in exploration, prefeasibility study, and related work.
• Resource Estimate (Historical): 727 Mt at 0.39% CuEq (measured + indicated). No current NI 43‑101 resource; verification required via drilling.
• Strategic Rationale: Early cash flow generation, reduced upfront risk, flexibility to expand as market conditions improve; positioning for strategic partnerships and offtake agreements in key Asian markets.
• Recommendations: Further geometallurgical testwork, detailed engineering, and engagement with lenders/equity partners to secure financing aligned with ESG requirements.
