Colours denote cumulative metres for each hole as follows: Aqua 0-10m, orange 10-20m, yellow 20-30m, red 30-40m, purple 40-50m and dark green 50m+.

The reason it’s hard to estimate any additional tonnage for this upgrade is that most of the JORC area had already mostly been drilled to the boundaries and it’s difficult to identify gaps in the block model with my basic spreadsheet and google maps project.

Anyway the best I can come up with is that the north eastern section on the boundary with Ionic appears to have found thicker than expected intercepts. Also, holes 270 and 266 (green) may have identified a down dip extension from hole 55 and if true, this could theoretically add 2Mt alone. (100x100x80x2.7). But to reiterate, I don’t know if the existing block model already includes this area.

i can also see a couple of areas with potentially thicker than expected hits (e.g. holes 269 and 274).

My extremely rough guess for the upgrade is that Colina becomes 65Mt or 66Mt.

i still need to go through weighted avg grades but my assumption is grade will get a natural increase with tonnage moving to M&I.
