Yes John, you have done what everyone needs to do , and that is apply common sense to the obvious. All exploration companies need to raise money in order to do the only thing that counts - that is drill , drill , drill, assay and drill some more hoping to prove a resource. Talk is cheap, and drilling costs money. That money is tough to raise, and if you do not produce the first time it gets almost impossible to raise more. The maket would attach more significance to one decent (not even spectacular) drill hole than all the talk. There are a hundred outfits out there that can make a compelling rationale for why you should invest in them, but so far, only NOT has the goods which take it well outside outside the "total speculation" category. I am not a geologist, but the greatest significance to me of gravity is that it holds my feet to the ground.
