RE:2023 Composite Average Grades-200 to 400m, 400 to 650 m
I wish to correct the drill depths of my previous post.
I assumed that the quoted depths were angle corrected..ie TVD ( true vertical depth.
An informed poster corrected that assumption .
In fact those depths are (MD) measured lenghts of the intercept.
The three classes of depths listed for interpretation of TVD are 1..79-95 %
2....40-70 % and 3 ...10 to 40 % .
A quick random check indicates #1 as the most frequent , so I have assumed a TVD of 65 % of MD.
The depths below are now TVD,,,
These include all zones of QWN.....
But, here are the results ..
130 meters depth to 260 m Depth ............3223 grams in 103 intersects avearaged 31.3 grams per ton ( 1 ounce per ton).
261 m depth to 430 m depth...................848 grams in 18 intersects averaged 47 grams per ton ( 1.5 ounces per ton )
Combined 130 m to 430 m ....4071 grams in 121 intersects averaged 33.5 grams per ton ( 1.1 ounces per ton )
The statistical lanes encompassing 261 to 430 m are quite wide due to very small sampling rate , so the average grade has quite wide sigmas.
But, it does show that QWN has economic grades down to the limit of current drilling ..430 m ...and that those average grades are probably no different than the top 260 m .
It would not be unexpected to see QWN a reprise of other orogenic gold discoveries which are being mined below 1 km of depth.
My aplogies for that that depth interpretation error..
