Mine plan and schedule

Tacmin has an established track record of assisting open-pit mining customers with short-, medium and long term mine plans and schedules in a wide variety of commodities for more than 20 years. During turnaround assignments we evaluate every plan and schedule for mineability and where the need exists, our expertise will assist with the amendments from where progress against the plans and schedules are monitored and conformance discussed during weekly planning meetings. Since all turnaround meetings are captured on video and accessible to all, implementation of operations ready mine plans and schedules are strictly monitored and adhered to.

Design and geotechnics

No mine plan or schedule can be sustained if pit, dump and haul road designs have not been checked and enhanced for mineability and operations readiness. Tacmin expertise has worked for decades together and in cooperation with the owners, team to assist with practical and geotechnical approved mine designs which have given cause to smooth implementation and optimal machine performance. Since any amendments to pit, dump, haul roads are collaboratively discussed and agreed, implementation and conformance closely monitored and captured on video; conformance to designs are instant and strictly adhered to.

Geology and ore grade

Tacmin’s core expertise is sought after for their ability to construct mining models. From structural to block models, Tacmin expertise has consistently been able to assist the owner's team to improve the mineability of complex geological ore bodies. Through multiple years of experience gained on a wide variety of commodities and open-pit mining, we have developed the skills to rapidly re-engineer pits and extract ore which was previously not easily accessible. Ore grade optimisation is critical during operations improvement assignments and our effective process applied during turnaround assignments ensures optimal ore availability at specified grade.

Budget conformance​​​​​​​

Mine plans and production schedules remain incomplete without an equipment resource analysis / requirement and associated projected cost of mining. By diligent management and tracking of conformance to the mine plan and schedule, budget compliance is carefully monitored and controlled. During ongoing operations improvement progress meetings, commitment and ownership becomes the order of the day.

Turnaround situation assessment

Once our customers have recognised the need for operational improvement, we do not spend months on end to assess the situation, instead, we immediately get stuck into short-term survivability. During this initial stage of turnaround, we work closely with the owner’s team to actively engage with MRM departments to determine the shortcomings and where applicable support the appropriate personnel to re-engineer and execute mineability assessments for implementation.

Based upon 21 years of experience gained during operations improvement / turnaround assignments, our operations turn-around team experienced that longer-term viability assessment is generally not required since the vast majority of longer-term viability is subject to securing the short-term future of the business through stabilising the distressed mining stage under consideration.
