RE: This Sounds Impressive...What does this mean?
Here's a comment from another board:
"Good to see they are using low cost biogeochemistry (BGC) as a reconnisance tool.
MAG found the Juancipico jackpot using the same technique in combination with an induced polarization (IP) geophysical survey.
GSM is looking for narrow veins, so BGC may lend itself to this task. Overburden soil geochem can yield indistinct values as a result of "smearing" of the alluvial sediment train. BGC is more focused....I'm well acquainted with these desert plants as they grow on my property in New Mexico.
Plants such as mesquite and creosote bush can send roots down close to a hundred meters, depending on local soil conditions and depth to the water table. Dorinho and I have done quite a bit of research on this subject, including discussions with Dr. Colin Dunn, retired from the Can Geo Survey, and an expert on BGC. FYI, greasewood and creosote bush are the same plant, just a variation in local place names... "
