The location of the first hole according to the recent American Potash presentation is fairly close to historic well Husky Fed 6-15. (I have assumed TRH started drilling TRH hole 1 according to the drilling graph in Presentation and 2011 Financials)
Skip to page 19. Drilling started 4687 feet using salt based mud. Page 21 also lists the rock formations and the expected depths. You can see from TRH's drilling update that drilling is at 4765 feet.
