Ann: Golden Rim hits more oxide gold at Kada, page-9

I did a similar exercise years ago in the lead-up to the Kouri maiden resource. Here are some Excel spreadsheet techniques I found helpful:

1. If you put the Easting and Northing measurements into the first two columns and plot them as X and Y coordinates you can map the holes to their geospatial locations (and even overlay over an image of the map if you like).
2. If you calculate the indicated ounces (g/t X length of intercept X selected radius² X π X conversion to ounces) and put that number in the third and subsequent columns (based on total yield) you can colour the points by inferred yield around each hole.
3. By playing with the radius of the points on the plot you can build a colour-graded 2-D plot.

That will give you a lovely visualisation of the resource. If you like the results I'd be interested to see it here.

With respect to estimation you can come up with an indicated resource by adding up all the ounces and playing with the "selected radius" mentioned above. Of course the indicated resource is only going to come from maybe 10% of the exploration target so you maiden resource total is going to be determined almost entirely by your assumption of what lies beneath the undrilled area. Augur samples are a reasonable assumption.

But in the end, whatever your methodology, the announced maiden resource will just be whatever it is. So have fun estimating if you find it fun. Otherwise close your eyes, breathe deeply, and focus on your centre...
