Sask coal exploration We all know about Goldsource. Most will know about Westcorp and Saturn. But for most of the others that made the rush in 2009 after Goldsource discovery, the other companies found nothing worth while. Kent Exploration still has SASK coal on their site but appears to have done nothing with it since 2009. Cloudbreak staked out for coal in the rush and is now Petro One Energy and there is no more coal exploration for them. Silverfield Resources...another flame out for SK coal. Westcan Uranium...another flame out for SK coal... Mill Bay Ventures = no further SK coal exploration.......So will NAG change the failure of these companies do discover what are coal deposits worth pursuing..............and we await........
