starting point of mining, it also facilitates decision-making
regarding the strategic placement of infrastructure, such as
the processing plant, heap leach pads, tailings dam, among
others. While the methodology is outlined, it is yet to be
fully developed.
RECOMMENDATIONS
For Case Studies 2 and 3, in the mine plan optimization
substage, it is necessary to run multiple iterations using
various mathematical algorithms with minimal constraints
to achieve improved results.
In Case Study 2, optimal sizing of mining phases
requires modeling the optimal sequence of pushbacks
through directional or mixed pits to represent operational
phases.
CONCLUSIONS
The HoV methodology provides a broad spectrum of solu-
tions represented through a net present value surface, which
aids in making strategic decisions in long-term planning.
For the case of multiple pit sequencing, the HoV meth-
odology is proposed to establish the commencement of
mining operations, focusing on key variables such as min-
ing capacity and the sequence in which pits are mined.
In the optimization of mine-plant capacity and mining
phase sizing, not only were more robust results achieved,
but also the NPV of the projects case studies was optimized.
