Comparison of the oriented data from ATV between nonmineralized and mineralized drill hole intervals in Spitfire. (a) Oriented data from the nonmineralized drill hole HK17-70. (b) Oriented data from the mineralized drill hole HK16-47. Note the change in orientation of the shear zone indicted by the arrows. (c) Oriented data from mineralized drill hole HK16-53. Note the change of the dip from the shear zone to the footwall. (d) Sketch showing the structural interpretation as a dilational jog opening within which the mineralization is trapped. Oriented data from drill hole HK17-72 is given.
