Probe was discussed by a couple of posters and a great job, here is one from Bentonstocks, which I think was very well done:

PRB is a low priority right now, but whatever is on their claims, whomever operates the Eagle 1 mine will want/need their ground as part of mine development. This thing will move up sharply, given the low float, when the time is right...I also spoke to the company Pres way back and they have some anomalies on their ground that appear to be of the same ilk as the one NOT made the discovery on. He did say they were smaller, but this could be because they are deeper. They planned to their ground prep work (geophysics, line-cutting, etc.) this fall in prerapartion for drilling the winter. I asked him if he could get a drill and he was confient that he could... For whetver that's worth. The other interesting thing about this company is that they have 5% net smelther royalty on a gold mine Agnic is putting production. The royalty only covers the claims that comprise this mine that PRB in its former life as another company optioned to Agnico, and Agnico has not been saying much to PRB about how much gold, or much of the mine is on these claims.

Here is another post by slidog on Probe:

Personally I just jumped into some PRB. Really low market cap - they just completed a private placement (3.5 million) and has an interesting property position relative to the chunk of luv that NOT is drilling.

RN has stated that this is open and headed to the north and southwest - PRB land is about 450m to the southwest and of course their property just to the north.

They completed their PP at .75 per share with NO FLOW THRU! (big plus in my book).

So, ripe with cash and good land position with a low market cap - as far as speculation goes might be a good deal for folks (it was for me). Probably 3-4 months until PRB drilling & assays actually show up (WAG on my part on that one).

I bought in at .82 if it drops over the next few weeks I will likely add more - if the in coming assays from NOT still show our chunk of luv headding in the PRB direction - likely a nice runup in the near future.

Hope this helps,
