In sambaza, soil from the pit is spread out in a thin layer on the ground. The miner then sweeps it with a gold detector. A nugget that was hidden in a heap is now close to the coil, so even a small piece gives a clear signal.
It works well with old pits and waste heaps that other miners already dug and left. Gold is often thrown away with the soil because nobody checked it.
Spread the soil thin and keep the coil close and level. Go slowly and check every signal with your hand or a pinpointer before you throw the soil away.
Watch our sambaza videos from the Mumbwa challenge to see it done in real time.
