RE: Some Points Being replete with turkey and having nothing better to do, I googled induced polarisation maximum depth and found that Quantec had done a survey in Northern Ontario to a maximum depth of 300m on 25 m spacing. So kudos to ProGeo.
This limitation actually works in our favour. Whereas we had only a sniff (sometimes a very good one) of copper\gold in La Escandalosa, we now have good reason to hope that the goodies do, in fact lie at greater depth. No-one knows because the instruments could not detect copper below that level.
So it's a whole new ball game. Wew have 45 km of strike which has not been tested at depth.
