Lycopodium performed a series of scopes that included completion of value-engineering to implement a new comminution circuit and upgrading the gold recovery circuit to process 8,000 tpd ore at the existing Aurizona process plant and develop capital and operating cost estimates to a Feasibility Study (FS) level (+/-15% accuracy).
Initial scope included review of the Pre-feasibility Study (PFS) conclusions that involved the implementation of a new 8,000 tpd comminution circuit to process fresh ore. Further scope included coordination and overall compilation of the NI 43-101 Technical Report, including developing sections related to the value-engineering exercise and input from others.
Additional scope included basic engineering preparation of mechanical, electrical design criteria and standard engineering specifications. Also, preparation of technical specifications and datasheets for long lead/critical path equipment items (jaw crusher, SAG mill and ball mill), including obtaining firm equipment pricing, bid evaluations and recommendations and award of two-part purchase orders (Design and Manufacture).
Project improvements:
- Reviews were completed and recommended the implementation of a low capital intensity, fit-for-purpose, operable and maintainable comminution circuit.
