"About now they should be in a position to announce aggregated costs and timelines based not on DFS estimates (which were prepared by contractors anyway) but on signed contracts, so they will have firmer dates and costs."
At the end of the day , it is what it is .
A Bankable Feasibility Study (or DFS) is +/-10 to 15 % . Without stating the obvious , some prices will come in under and others over budget. "Most" projects do not come in ahead of time and under budget . The issue with refurb's is the "hidden or unknown" costs and budget assumptions like costs of electrics (eg., probably will have to be completely redone , etc.)
The old saying in the industry is "You can have a good project or you can have a cheap project , but you can't have both!" because to have a cheap project , quality must be compromised.
Again , the Iron Triangle of Project Management.
Having said that and as others have noted , the market has already factored in completion and first gold pour in Q1 , 2019 .
