Pre-feasibility studies

Pre-feasibility studies (PFS) are used mainly for due diligence work helping project developers determine whether or not to proceed with Detailed Feasibility Studies. PFSs are done by factoring known unit costs and estimating gross dimensions or quantities once Preliminary Economic Assessments (PEA) or scoping studies have been completed. PFSs use project specific metrics and this is what sets them apart from PEAs, which are generally based on industry standards rather than derived from detailed site-specific data.

PFSs include options for the technical and economic aspects of a project and are used to identify whether or not continuing exploration for example for mining and oil&gas projects or to attract a joint venture partner.

The Phase VI Preliminary Feasibility study (PFS) is to build on the SRK 2010 Phase V PFS. This technical report includes: New or updated mineral resource and/or reserve estimates including Minto Main and Minto South Deposit (an amalgamation of the deposits formerly called Area 2/118, Copper Keel and Wildfire); new life of mine plan that incorporates additional underground mineral reserves from the Copper Keel and Wildfire deposits; updated cost and economic analysis estimates; processing plant capacity improvements.

The conclusions states that there continues to be strong exploration targets in the vicinity of the known deposits. The Phase VI Underground deposits (Copper Keel and Wildfire) are an increase in reserves that add value to the Minto Mine by increasing the NPV of the overall project with a minimal capital investment requirement into Explorations Ltd.

The Minto Phase V Preliminary Feasibility Study (PFS) Technical Report builds upon the 2009 Phase IV PFS and includes the following modifications: New mineral resource and/or reserve estimates including Minto Main, Area 2/118, Minto North, Ridgetop and Minto East; new life-of-mine plan including, underground mineral reserves; updated cost and economic analysis estimates; changed tailings disposal methodology; and processing plant capacity improvements.

The conclusions states that Minto deposits, Phase V pits and underground, contain a significant mineral reserve. The Phase V deposits are estimated to be economic to exploit and, according to the assumptions of the study, add value to the Minto mine by increasing the NPV of the overall project.

The Minto Phase IV Pre-Feasibility Study (PFS) Technical Report was compiled by SRK Consulting to describe a new mineral resource and reserve estimate and also to describe the new life-of-mine plan with cost and plant capacity improvements.

The Minto deposit, encompassing Main Pit and Phase IV pits (Area 2, North, Area 118 and Ridgetop), represents a significant ore reserve. The Phase IV deposits are estimated to be economic to exploit and adds value to the Minto mine by increasing the NPV of the overall project.
