Strategies for developing districts with mining assets require optimizing mine planning, evaluating extraction methods and analyzing the transition from open pit to underground mining. Assessment of the optimal mine capacity and a risk analysis are also carried out to ensure safe and profitable operations.
The main strategic planning areas addressed by REDCO are:
✓ Multivariable analysis for district development.
✓ Optimal mine-plant production capacities.
✓ Selection of extraction methods to optimize asset valuation.
✓ Cut-off grade optimization under risk-return criteria.
✓ Optimal transition path from open pit to underground mining.
Mine 1
Polymetallic mine / 4,000 tpd
Peru – Greenfield project
Open pit/Sublevel Caving
Development of a flexible mine, maximizing mining recovery and ensuring continuity.
Mine 2
Diamond mine / 11,000 tpd
Eastern Europe – Brownfield project
Open pit/Open stoping ⇒ SLC ⇒ Block Caving
Design of an underground mine that maximizes diamond recovery in low-grade rock at great depth.
Mine 3
Fertilizer mine / 14,000 tpd
Brazil – Brownfield project
Open pit/R&P ⇒ SLS ⇒ SLC
Highly complex open pit operation due to the location of the ore and the need for blending for the plant. Design and planning of an efficient, flexible and modular underground mine.
Mine 4
Iron ore mine / 40,000 tpd
Chile – Brownfield project
Open pit/SLC
Operational continuity project for the Los Colorados mine, maximizing the recovery of economic resources located outside the pit limit.
Mine 5
Copper mine / 135,000 tpd
Chile – Brownfield project
Open pit/Block Caving
Design of a drawpoint layout divided into zones according to rock quality, maximizing recovery and reducing dilution.
Mine 6
Copper mine / ~200,000 tpd
Chile – Brownfield project
Open pit/Block Caving
Design and planning of a modular mine under a strategic concept that ensures operational continuity.
