Huarón

1. Project Overview

The Huarón mine is located at 4,534 m.a.s.l. and operates using cut-and-fill and long-hole mining methods.

2. Project Challenges

• High-altitude operations.

• TSF raises and closure processes.

• Stormwater management in high-precipitation conditions.

• Seepage control and physical stability assurance.

3. Our Approach and Solutions

• Feasibility studies for TSF closure using waste rock.

• Reinforced soil wall design for dam raises.

• Advanced geotechnical instrumentation.

• Grouting reinforcement techniques.

• Seepage and stability modeling.

• Dam break studies and hydraulic structure design.

• Implementation of stability buttresses.

4. Results Achieved

• Detailed engineering for closure of TSFs 1–3.

• Successful raise of TSF No. 5 using reinforced wall systems.

• Optimized stormwater management.

• Continuous CQA during raise stages.

• Updated operational manuals and monitoring systems.
