High-grade gold-copper open pit and underground mine case study
AMC’s mine redesign helps client save $215m and increase ore reserves and productivity rates
Project Overview
As part of a decade-long partnership, AMC provides expert advice and ongoing operational and strategic support to this complex mine.
The challenge
The project required AMC to identify and rank the best combinations of open pit and underground mining options for the mine’s transition from open pit to underground.
The result
- $215m cost savings in reduced waste movement.
- Access to high-grade underground ore was brought forward by two years.
- 33% mine productivity rate increase from 1.2 Mtpa to 1.6 Mtpa over a longer underground mine life.
- Reduced open pit waste mining by nearly 70 million tonnes.
- Improved project economics including increased cash flows and a longer mine life.
Our approach
Our team started with a strategic mine plan to identify potential options, followed by detailed mine planning to refine the options. Drawing upon a unique set of tools, methods, and proprietary data, we rapidly evaluated and presented a clear recommendation.
