Re: Drilling and Darcel...Nickel, you any good with Math?

The company is exploring for nickel deposits on its Langmuir property near Timmins, Ontario; for nickel-gold-copper on its Cleaver and Douglas properties; and for molybdenum and rare earth elements at recently acquired Desrosiers property.
I was up last night fooling with the spread sheet and as I had written, Darcel had used only the single hole reported for Langmuir 1 South that was reported Mar 07/07. Using that one hole he estimated 2.6 million pounds Nickel.
I was wondering if you could go through that simple calc and see what you get? I got more? Almost twice more, and wondered what I had done wrong? I simply used the method that we had talked about him using earlier in a previous post
I will lay it out for you:
The estimate methodology:
1) multiply core length (m) x 625 (assume each core represents an area of 25m x 25m). Gets the volume of the core sample material.
2) multiple volume above x 3.5 (tonnes per m3) .I assume this is to calculate tonnes from the volume calculated above?
3) multiply tonnes x 2204 to achieve lbs. of Ni containing rock. Gets you to LBS from Tonnes
4) multiply (lbs. Ni containing rock) x (avg. Ni grade) to obtain lbs. Ni per core sample. Gives LBS.Ni. per core sample
5) add all lbs Ni. from all core data, to obtain total lbs. Adding up the Nickel per core gets you total Ni for a given set of drill samples/cores in any given area
Now here's the single hole info:
