We all have our preferences about what kind of ground we like. I explained that I steer clear of patches that have been dug time and again over the decades. I agree that there is still gold. Have at it. That's not the gold I'm after.
Now you mention the fringes; if by fringes you mean "a few canyons over", then again, I'm with you. I'm not the sort to start sweeping were I notice the last unfilled hole in a patch. To me, that's still a heavily worked site full of shot. If there's nice gold still to be found, that's great for people who don't mind high trash ratios in well travelled ground.
I'm not betting on finding the one auriferous draw left that hasn't been dry washed.
I like to imagine the thirsty OTs dragging their equipment and arses miles from water and roads. There is plenty of coarse gold that was too hard to get to be worth it in that time. So OTs would scratch about, get a little easy gold, and move on if there wasn't enough to survive on. They would have got more if they had the tools and tech I have, but they didn't.
Finding that abandoned gold 5 miles from the nearest donkey trail is rewarding to me. And yeah, if there was rich gold there, there would be a road leading right to it, obviously.
When someone says "I don't like heavily worked areas, even if they have good gold, I prefer to roam extremely tough places far from roads even if it means I have to work harder for less gold", you probably shouldn't immediately blurt out "hey, do your own work, there's no free lunch, stop trying to freely exchange general ideas with likeminded people on a very specific forum that exists for that purpose!"
According to my original post, someone might answer something like: "California side of the Sylvania Mountains. There's no active claims, but it has produced small amounts of native gold and won't be full of trash because it never warranted heavy traffic. There's not much for access or water, but that's what you asked for right?". To me, it seems a reasonable question and rational reply. Maybe I'm missing something.
