TAKING No. 8 KWADEMEN INITIAL DRILL RESULTS AND ESTIMATING RESOURCE......
I was impressed by Kwademen past drill results. It may turn out that Kwademen and Kwademen South are linked and this forms one long target zone.
At Kwademen, historical work has returned several encouraging gold intercepts in broadly spaced drilling
(~200m to 300m line spacing) including:
• 16m @ 1.07g/t Au from 69m
• 10.4m @ 2.14g/t Au from 191m
• 23m @ 1.53g/t Au from 143m
• 2.25m @ 7.74g/t Au from 155.8m
• 1.45m @ 16.0g/t Au from 52m
• 1m @ 40.0g/t Au from 90m
"Soil sampling conducted by Panthera over the last two years has shown that this drilling is located to the
west of the main gold in soil anomaly and also west of the area of artisanal mining activity (Figure 3). The
main part of the gold in soil geochemical anomaly and associated artisanal gold mining activity CAN THUS BE SEEN TO REPRESENT A HIGHLY PROSPECTIVE 'WALK-UP' DRILL TARGET, with over 1,000m of strike potential."
Based on the above statement in the RNS (i.e. these (HIGHER GRADE) results are from the WEST OF THE MAIN SOIL ANOMALY AND CAN BE TAKEN AS REPRESENTATIVE OF THE MAIN TARGET ZONE), I have attempted to see what sort of resource we are likely to get at Kwademen (North):
ASSUMPTIONS / PARAMETERS USED:
(a) Strike length - given 1km (=1000m)
(b) Depth =It appears from the above drills that they have drilled up to 200m
(c) Width =Not given - Hence I will give 2 estimations based on 500m and a reduced width of 300m
(d) Density for the area = assumed industry average in west africa = 2.4 Tonnes / meter cube
(e) As with Labola, I have taken only 1/10th of the total calculations to account for the fact that some high grade outliers are ignored as they could be in isolation and the width and depth may not be the same throughout the whole strike length. I have indeed also reduced the strike length itself by taking only 1/10 of the overall result in case it was not continuous throughout.
(f) Recovery rate of gold = 80%
So, here goes:
1) Estimated Tonnage = [1000m x 500m x 200m] x 2.4 T/meter cube = 240,000,000 T2)
(2) The average grading works out to be 2.87grams per tonne as follows:
% OF EACH DRILL Grams per Tonne
----------------------- -----------------------
29.57% 0.32g
19.22% 0.41g
42.51% 0.65g
4.16% 0.32g
2.68% 0.43g
1.86% 0.74g
--------
AVERAGE 2.87g
=====
Based on the above average of 2.87g/T, the calculation will become:
(2) In grams = 240,000,000 T x 2.87g/T = 688,000,000g
(3) In ounces = 688,000,000 /34.2857 AND dividing by factor of 10 = 2,006,667 oz
(4) Recovery 80% = 2,006,667 x 80% = 1,605,334 oz.
** If the width was only 300m as opposed to 500m, the end result would be 965,000 oz **
