If you want to get a fair idea of how the resources has move through the various points of exploration , you can compare the following chronological flow of different milestone reports which culminate in the end one being that of which was reported by the Government of Quebec in a 2019 - 2020 report tabled on mining and minerals in their Province.

Before we do though it is important to get in your head that where they say ' Proven ' , this means ' Measured and Indicated ' and which in accordance with JORC as well as their Canadian Equivalent NI143-101 Technical determination Instrument of reserves which are largely governed by the carrying out of Drill works with Measured being based on comprehensive tightly spaced drill programs which have reliably proven up the economic resource with Indicated also being represented by actual drill programs albeit to a lesser extent of depth or spacing - Whereas ' Probable is equivalent to ' Inferred ' and are usually yet to be supported by drill programs and are more constructed on the Geological Interpretation of the zones and intrusions.

So I'm no Geologist , but the idea is that you see a move from ' Inferred to Indicated and or Measured as you undertake further Drilling programs.

So the FIRST results table shown below are largely the summation of ALL the Historical results compiled through to the years of 2009 - 2010 with the SECOND and THIRD table taken out of the Companies feasibility studies and a BBA Engineering table at around the 2012 time frame. The last table of course clearly shows the Governments interpretation of the ' Probable Reserves' based on what would have been available privy to their obvious Investment position on the project from 2018 - 2019 geological data from the Company. You can see by the differences that some ' Tonnages ' of resource have been effectively removed by their relatively short period of production and extraction at the operation.

So you can get a fair idea from this flow of defined resources that their is still a very significant available tonnage of resources ....virtually 90 % which is still ready to be extracted and processed.
