core of hole KL12-01 maybe of interest:
.................................................................
As noted in the Eastwest Resources report below, the company used a drill that cored a core that is 42 mm in diameter, .......
R.S.Middleton P.Eng was the Exploration Manager of EWR at that time
.
currently, Mr Middleton is VP of Exploration for Giyani Gold.
.
since the 42mm size produced better results, we'll assume that the same type of drill was used to produce the core from hole KL12-01
.
.................................................................
Annual report 2004 Norton property [Ontario ]
.
"All Drilling completed in 2002 and 2003 used a Longyear 28 drill that cored a thinwall B core that is 42 mm in diameter compared with the previous AQ (27 mm).
.
This yielded a better sample and better recovery."
..................................................................
since 42 millimeters = .042 meters, the core's diameter is .042 m . with a radius of 1/2 that of the diameter [ .021 m]
.
[1] volume of the KL12-01 core:
pi x radius[squared] x length
3.14 x .021 x .021 x 15.1 =.0209096 cubic meters
.
[2] core tonnage = cubic meters x specific gravity = .0209096 x 4.2 = .0878202 tonnes
....................................................
[3] from the news release: "13.162 g/tonne Au over 15.1 m"
expressed slightly different:
there are 13.162 grams Au in one tonne [of material of the same composition as the 15.1 m core].
.
grams Au in 15.1 m core = .0878202 x 13.162 = 1.155
troy oz Au in the 15.1 m core = .0371 [1.155 / 31.10]
.......................................................
also, the core can be expressed in the following units:
49.54 feet length
1.65 inch diameter
193.2 lbs weight
