That's just the avg intersected thickness and avg grade in the fresh dolerite. It would be reasonably close to a geostatistical estimate.
If I do a weighted avg grade which is more accurate it cracks 7Moz.

More data will help but you can see where this is headed.
There's a good chance that it's mineralised from the Tabocal workings (3km East) to the Daniel workings in the west - that's 5km of strike, then there's the additional 5km NNE above the dog-leg with gold in the soils. The dolerite is minimum 600m wide and the holes are mineralised to EOH. How deep do you think a dolerite 10km long and 1km wide extends vertically? Then add in Ema which is up to 2km wide and 20km long.
I posted some very, very large numbers with lots of zeros a year ago. Back then I used a ore:waste factor of 2-10% to stop the zeros from filling up the page. Looking at the drilling results I'd say that I was being way too conservative. Right now that ore:waste factor is looking like it's a lot closer to 100% than 10%.
This is a fun way to put it: This drilling has tested 0.0062% of a given volume of dolerite 1km wide x 30km long x 1km deep, but let's not get too far ahead of ourselves....
For the dolerite between Daniel and Tabocal workings (5km x 600m) to a depth of 200m (1.8Bt), drilling results from the 4 holes has tested 0.3% of the volume. Now solve for 100% of the volume, i.e. divide 7Moz by 0.3%. I do love playing with numbers when they are measuring ounces of gold!
