RE:RE:RE:NexGen is VERY SpecialI assume you are modeling A2 zone only. Is that correct? I modeled by calculating a weighted average grade for both A2 and A3 zones, and used a very conservative density of 2.6. Calculating a weighted average grade for each zone, and then using NXE's data for dimensions of each zone, will give a good approximation of total pounds. I have found this will provide a number not that much different than using a block model and a lot less work, and good enough for my investment purposes.

I model each drill hole by section by section, calculate a block model around each drill hole or holes, adjusting the specific gravity above 2.6 for really high grade sections, use the average grade of the drill hole or holes to give the average grade for that specific block. Remember a drill hole is a sample.
By doing this, you really get to know the orebody and I know all the assumption that I make. Sometimes the the assumptions might be too agressive, sometimes too conservative, but it all averages out in the end and I get a good sense for what is there. I could use a computer model, but I find inputting directional holes quite difficult and putting in all the block model assumptions is a task. A friend of mine is using software to model the deposit and frankly, some of the assumptions being made to model the orebody are dumb, so I think the end result is not as reliable as doing it by hand.
The key to this orebody for the semi-lazy investor is to model only the high grade sections around 44b. I is pretty clear, there is a lot of uranium around that drill hole. If you assume a 20M strike, there is 40 million lbs. As the other higher grade sections come in, you can start joining them up. If you get just the high grade modelling right, you are most of the way there. If they pick up the high grade zone to the SW, it will be the key to adding resources. Basically, every 10 Metres of strike of 44b type material adds about 20 million lbs to the resource, do the math, it is pretty simple. If they pick it up on the high grade zone under the 200M minteralized stepout, that will be a gamechanger. Even the semi-lazy modeller can figure that one out.
