This estimate was calculated with Gold price @$500.
It's double now~ We are valued over $1,000,000,000 in ExPL7/94 alone. JMO

Gold content in ExPL7/94

(a) In the Pampana Channel:

(i) Assume the grade of 0.811gm/m³ recovered by 1950 Dredge for a section of the Pampana, south of ExPL7/94 holds good for dredgeable sections in ExPL7/94, then the gold content is 973 200 gms or 31.293ozs.

(ii) Assume that depletion due to illicit mining over the years is set at 30% then the gold content is reduced to 21905ozs.

(iii) At US$500/oz. The estimated gold value is US$10,952,000.

(b) In the Flanking Flats and Terraces:

Geometric Mean Grade = 0.0329oz/yd³
Gravel Volume = 47,155,200yd³
Assume 70% of gravel would be economic, volume is reduced to = 33,008,640 yd³
Gold content = 1,085,984ozs.
Depletion of 15% Gold due to previous mining – lawful and illicit: gold content is reduced to = 923,087ozs.

At gold price of US$500, the estimated gold value is US$461,543,500.

(c) The estimated gold value contained in ExPL7/94 is US$472,495,000
