Hello 1king, Excerpt from your post #1254 on June 1, >> Spent about an hour or so checking out the Gallery Website. Sorry >> to say the MT was a waste of cash but it was a waste of cash. >> These were the aims quoted on the site: >> "A. to determine if a previously outlined airborne magnetic >> anomaly was associated with enhanced conductivity at depth >> B. secondly, if enhanced conductivity was detected, to provide >> an estimate of depth and area extent of the anomalous region" >> Large Loop TEM would do this far better far cheaper. Due to results from their geophysics, Gallery included the possibility of having a deep conductor on their property. See their April 17, 1997 news release.gallery-gold.com Large loop TEM is apparently only capable of detecting mineralized zones down to approximately 2100 feet (See post #1253 by Kent C.) siliconinvestor.com As per this post, Gallery is now planning to do a LL TEM survey after finding that the conductor is not as deep as previously thought. Being a novice at this game I'm not aware of all the advantages or disadvantages regarding technical details of geophysical techniques - I just absorb what a few people have to say, do a lot of reading, and come to my own conclusions! IMO, The MT survey was ideal as per reasons outlined in the two links above. My opinion is shared similarly by Terry Crebs. See post #573.siliconinvestor.com Something that's been bothering me and I'm surprised it hasn't been mentioned yet is the fact that the MT survey outlined the larger, more conductive body to be at a depth of approximately 2700 ft and stacked below the smaller, less conductive body which they have already found. The borehole surveys done have now found a "good quality" off hole anomaly at 1730 feet, corresponding to the mineralized zone they have discovered. My question, Does this off-hole anomaly at 1730 feet correspond to the larger, more conductive body outlined in the MT survey? If so, then why was Gallery so "off" interpreting the MT data? If not, then I guess the larger conductive body "disappeared" when they conducted the BH surveys as they have failed to mention anything about it. Maybe Kent C. can shed some light?
