High grade zone19 Nov 2020 16:02
What measurements do we have of the HGZ
It's split into 3 layers and we've been informed that the highest grades are in the top layer
Top is 55 long x 20m wide x 230m deep =2,530,000 cu m specific gravity 3 and a grade >3-5g/t using 5 as the high side
= 1.22m oz
Middle 400 x 20 x 200 = 1,600,000 cu m
x3 sg x 3g/t = 463,000 oz
Lower 300x 20 x 300 = 1,800,000 cu m
x 3sg x 3g/t = 521,000 oz
Total = 2,204,000 m oz
In June Rns the Breccias adjacent to the HGZ had figures of 550 long x 100m average width x 630 m deep
= 34,650,000 cu m
x 2.75sg for breccias
x 2g/t (reported breccia grades are highest against the HGZ)
Therefore Breccias volumes = Breccias-HGZ = 2,981,000 oz
Therefore total ounces for this first MRE resource = 5,185,000 oz
There's a but a big BUT
The depth for the HGZ is 730m
The depth for the breccias 630m
They've stated that the Breccias have been observed down to 1,000m and increased to 1,100 in the last Rns
550x100x330 = 3.2m oz additional ounces.
I don't believe the extra depth will be in this initial MRE
