TRX Presidents Corner: NI43-101 HIGHLIGHTS Mining Methods 2017-06-07
The current study is based on a Geological resource model by Venmyn Deloitte (2014) at a cut-off grade of 0.5g/t Au.
The study conforms to criteria defined in the Environmental Impact Assessment (EIA) and with special regards to minimizing the open pit mine footprint. The study also conforms to the Buckreef Gold Company Ltd’s reserve and resource estimating procedures and guidelines.
Different open pits will be developed to provide the ore feed for the Carbon- in-Leach (CIL) operation. The topography over the area is generally level, with gently rolling slope towards Nyamazovu and Nyamazama rivers. The conditions are well suited for open mining and no major physical obstacles are apparent.
The mine facilities will be sited to minimize impacts on the river channels and environment at large. Mine plan and equipment selection addressed the following key items:
Compliance with approved EIA and development consent conditions.
Target ore production during commercial production to be up to
1,500,000 tonnes per year
Open pit mining methodology.
Selective mining of ore and associated waste to maximize reserves.
Rapid vertical development to maximize NPV.
Maximization of pit slope angles.
Minimization of unit operating costs using the optimal applicable
