Updated Resource AssessmeOne obvious factor that I should have mentioned is that in the process of carrying out the cutback for the first mining bench , they probably took bulk mining samples of the exposed high grade ore beneath the over burden.
Mining is essentially bulk mining on a larger scale.
What bulk sampling of multiple samples of say, 20 tons of ore will do is validate the commercial economics of the ore than has previously only reached the M&1 43-101 categories via drilling.
In other words more of that high grade shallow ore will be converted to 2P reserves, thereby extending the life of the current expansion.
If I recall correctly , the tailings ponds have extra capacity above the mine life of the current expansion ( 8.5 years ) based on the June 2022 resource estimate .
So it makes sense to update our 2P reserves..
