Sudan gold miners vie with archaeologists for desert riches
We actually had a Sudani guy pan for gold with some soil samples from one of our sites.
Interesting that the gold rush is going on. I understand the concern for archaeological sites, but most of the guys who served as archaeological workmen probably realize that there usually isn't much left in the way of gold in most of the cemeteries - they were typically robbed in antiquity.
Competent excavators were finding the different colored in-fill after removing the tomb superstructures that showed exactly where ancient people were tunneling to grab valuables - usually they went right for the head/neck, sometimes near the pelvis for belts or girdles.
