William, This should not just be "commended" this "geophysics prior to drilling" should be required. The companies have the responsibility to approach these projects in a systematic way. Deviation from the norm as dictated by "professional opinions" (see TC's comment) should have to be publicly justified as these companies are spending our money. Another example, as I believe opinions without support are rumors: This is taken from exploration on VBE-1 in 1997 by Columbia Yukon Resources Step 1 Quote Following completion of three north south lines of magneto-telluric (MT) surveys, which defined distinctive conductors with a roughly east west alignment in the south central part of VBE-1 on Line 14.0 west and Line 0.00 (midway point of the property), a further MT survey was carried out which confirms results of the earlier survey. Two infill lines, 10.0 west and 6.0 west, were completed between Line 14.0 west and Line 0.0 west and extended to Line 5.0 east. Preliminary field analysis of the new data indicates an east west conductor extending for 1.9 kilometres originating at a depth of greater than 1000 metres. DDH #97-4, was recently collared on Line 14.0 west to investigate the source of the MT anomaly and has reached a depth of 742 metres. DDH #97-5, collared approximately 1200 metres north west of 97-4, currently at 510 metres, is testing a different structural block underlain by an anorthositie unit extending east west through the central part of VBE-1. Subsequent drill holes will be sited to test the geophysical targets delineated by the MT, down hole Pulse E.M. surveys or unique structural blocks. Step 2 Drill Hole 97-4, targeted to test a magneto-telluric (MT) anomaly, is at a current depth of 1300 metres, drilling through leuconorite rock. No sulphide source for the MT anomaly has been identified in the drill core, and a downhole Pulse EM probe of this hole will be carried out before moving the drill rig in order to ascertain if conductors exist adjacent to the hole. A detailed review of the MT surveys has noted that the strongest anomaly occurs 400 metres east of Hole 97-4, and probe readings from this direction will be evaluated for the targeting of an additional drill site on the anomaly. Drill Hole 97-5, currently at 1150 metres depth, is coring anorthosite. This hole will also be tested with a Pulse EM probe. Step 3 The location of hole 97-7 was selected because the geological setting indicates that this structural block may be unroofed by erosion to expose deeper levels in the favourable intrusive rocks. Possible deep geophysical targets in the area appear to be masked by the close proximity of a sea inlet. The conductivity of salt water causes its own large anomaly all along the coast line. Drilling will continue to a targeted depth of 1,500 metres, and is expected to be completed before the end of October. unquote As we know holes 4 and 5 drilled a lot of "rock" and never found the "source" of the MT anomaly. The geological bailout hole 7 his the only "significant" sulfides. Falco has subsequently dropped the option! This is just one example! 1King P.S. We all appreciate that no method is completely "foolproof" but some are a lot more efficient than others. MT has plenty of excellent applications but not (IMO) in early stages of grass-roots exploration with limited budgets and tight economics.
