Goldstorm resource estimate: +/- 8.6 million oz for 300HHey folks, I had a few moments to complete my back-of-the-envelope calculation for the Goldstorm 300 Horizon.
My envelope has some detail inside, which is basically a spreadsheet with all the drill results plotted, including azimuth, dip, etc. Best I can do without having Leapfrog or similar. My estimate can be thought of as a loaf of sliced bread, with each Section representing one "slice" of toast.
Each slice/section has it's own resource calculation. The totals of all the slices make up my total for the GS 300H. The grades for each section are weighted averages (for intersect length) for all the 300 mineralized sections. I used the drill traces to try and ensure I placed the drill results in the correct section. Traces were also used to help estimate the width of each section. I had to make a number of assumptions based on limited info provided, so I did a fair amount of manual massaging of the data.
Results:
387.7 million tonnes grading 0.67 g/t Au (and 0.73 g/t AuEq)
Gold: 8.629 million oz Au (and 9.433 AuEq)
Highest grade section: 112+50 at 0.84 g/t Au (0.94 g/t AuEq)
Highest resource section: 112+50 at 1.972 million oz Au (2.207 million oz AuEq)
Other thoughts:
There are some places where gaps in the drilling were a little wide. Depending on the closest other drill traces, I either excluded nearby results from the calculation, or assumed most likely they should be included. Think of it as swiss cheese; do you include or exclude the holes in the data. My expectations are that there are sufficient gaps that the NI 43-101 may have to exclude some portions that I included. Therefore, the resource calc for the 300H may actually be lower than what I have stated.
Note, I only included the 300 horizon because it has far more drilling data, is a larger zone, is almost certainly to be mined first, and is higher grade than the other two zones. If they are included in the NI 43-101, I assume their contribution to the total resource will be less vital.
My own view is that folks expecting much higher numbers in this initial resource are far ahead of the drilling to date. It may eventually get to the numbers thrown about, but it will need another major drilling season at least, to get there.
