I know where one pipe isIn Strike's corporate presentation on pages 8 and 11 there are aerial shots of circular lakes that look like kimberlite pipes. Now fly to Contest Lake, SK on Google Earth and look 2km south west of the lake. You will see a circular lake 200 m in dia. (55 degrees, 16 min. 14.30 sec N; 103 degrees, 13 minutes, 08.01 sec W). Now go to the 'Till sampling indicator map' in the 'Maps and Reports' section of their website. Their highest density till sampling, much more than in any other area, is centered right beside this round lake. I rest my case. There are other peculiar round lakes in this area as well. The Mookster
