Most of the areas you described have been hit fairly hard however I was out there two weekends ago and saw nuggets from 3 gram down to unreadable come out of Durikai north and carbean rd.. all up I believe it was 8 nuggets between two people.. trust me those areas have seen a lot of detectors and people are still pulling gold out. I'll be back out there for a long weekend Labour Day weekend. I believe Tribsa 56 is going out the weekend after Anzac Day... I would camp at Karara on a long weekend and you'll bump into other like minded people as I have. I've learnt a lot about the area over a few drinks around a fire at the camp.. most of the people I've met out there a very friendly and helpful.. there has only been one or two people that were unfriendly so you just leave those clowns alone.
Best luck
If those 2 people initials start with C&M then they have been getting their nuggets from areas not allowed. Example is the Scientific Area. They also raked the hell out of Carbean Road Diggings and spend many a day there. I pulled a .24gram nugget in front of them from the side of their rakings. But that was lucky because there is not too much in the common areas, or easier to get to areas.
They are an elderly couple, so that is one advantage to others who just want to go once in a blue moon to find just any colour. Go in the harder to get to areas, there is still small patches around, but they are scattered and off the beaten track.
In regards to friendliness, the couple I mentioned were friendly, yes. I never had a problem with their people manners. It was the other aspects that I think are not to be taken lightly, and its actions like that, that can spoil this hobby for the rest of us.
So know there is gold out there, but if you are detecting an area that is 50mtrs or so close to a track, then chances are slim. But in saying that, some patches have recently been found not too far from the main tracks, so the old saying of gold is where you find it is truly the case.
The areas they opened up for prospecting are not the richest areas, far from it. But they do contain gold.
Good luck, hope you find some nuggets.
