In reply to above poster agnusbeans :
An area of 62,662 (63 hectares) seems quite large , I would use an approximated true width multiplied By strike length to get area
Just off the cuff and showing the method I use .
looks like it is 400 M of strike with an average width of 20 meters that is only 8000 meters squared or 0.8 of a hectare (no that I use hectares but it is how you look to have calculated it on a footprint basis .

8000 * say depth 100 meters = 80000 cubic meters * SG 3 = 24oK tonnes of possible ore then multiply that out by a grade % of say 2% to get 4800 tonnes of Cu

I get around 3% of your tonnage of Cu even though I went down an extra 20 meters in depth - one of us is out in a big way
