Makes me wonder if there's silver like that in my area or if I just don't know what I'm doing.
I wonder the same thing. I do the research, have site A and B, both are old, urban sites, and look sweet on paper. Both are huge. Spend hours and hours on site A and it is a complete dud (just one rosie and a couple of wheats), and site B is absolutely loaded. How is that possible? I find it hard to believe they pounded site A, and ignored site B. Both sites are very trashy, so I think that is controlled for (tho site B has much less ferrous trash).
It may be that I'm getting better with the E-Trac, and I should try site A again (tho I hate wasting more time on proven duds). Last time was in the spring. It may be that site A was regraded, but from the old trees and various cultural features, that seems unlikely.
So, in my case, I think what it comes down to is mineralization. We have some extreme, but very variable mineralization. I just think the deep ones are out of reach at site A due to the mineralization. But, now that I'm learning more how to play with the channels and the manual to try to work around the mineralization, perhaps site A can be tried again. So, its just something to think about. Maybe mineralization is keeping the deep ones out of reach for you at some sites.
I'm far from making conclusions about channels and mineralization (or even if there is anything to it at all, but the evidence so far suggests that there is), but I spent a ton of time on my last hunt playing with it, trying to get the right channel and man level for the ever changing ground at my current site. So, I dunno.
But, its also the case that large sections of site B also appear to be duds, so I guess you just never know, but I'm constantly thinking about it.
