I remember BH saying I cut off is 1000 ppm, and they had 77 holes with values hugely over that cut off with great depth as well. As the area is so vast and as they collate all the details I am sure a mining plan will involve cherry-picking the best areas with high profit margins at the same time, they will need to keep working on their metallurgical costs as we know the cost of mining will not be expensive as it starts from the surface in most areas. please note I am looking at this from a common sense point of you which has benefited me hugely in the past, but I am not a professional and able to go into the details of it.
