Mumbo - this is a post by Bamps on 13 Aug. It excludes the lower ovoid which makes up the rest of the ore body. Bamps will be able to direct you to the full calculation.
I started off with an ovoid shape plan and gridded it with 50m squares, around the perimeter were squares that had the perimeter running through them forming triangles and rectangles.
I went right round the perimeter calculating each part square, then adding this to the number of 50m squares gave me a fairly accurate 176,000 sq m.
Multiply the area x 1300m depth = 228,800,000 cu m
Multiply x specific gravity of 2.7 Used by Ggp = 617,760,000 tons
I’ve used a fairly low average grade 0.75g/t
Multiply 617,760,000 x 0.75 = 463,320,000 grams
Divided x 31.1 = 14,897,749.2 oz
If this turns out to be 1g/t which is highly likely then the total sum = 19,863,665 oz
I’ve not included the lower ovoid figures but there is at least 10m oz @0.75 g/t or 13.5m @1g/t in the additional zone if my assumptions are right and it’s still open SE,N,E,NW and of course at depth .
I’ve not deducted any dilution which the industry norm allows 15%, but there’s nothing like 15% is this vertical ore body.
