The source of the boulders This is quoted from the Seeking Alpha article of Malcolm Shaw's in the question/answer comment section of it:
I was thinking tonight about the recent hole, 13-038... Interesting thing is that it is ALSO NOT the source of the boulders that are at surface. There is 20m or so of unmineralized rock on top of the mineralized interval, so the boulders couldn't have come from that location. There are two conclusions: 1) that there is ANOTHER "discovery area" out there, and/or 2) one of the existing discoveries has some real size.
Here is what the source area of the mineralization at PLS will look like:
1. Lake water
2. Just gravel below the water
3. The uranium ore will be immediately below the gravel with the gravel sitting on it with the basement rock exposed from the scraping off of the basement rock above the orebody.
Everyone will know when the source is discovered. Believe me. Right now the drill team are closing in on the monster, hole by hole.
