Preparation of rudimentary sluice for ore processing in Uganda

This is rudimentary sluice that is being prepared by our neighboring miners. In my opinion this type of the sluice is way to wide, not evenly balanced, with too steep slopes, and too high to load it with the ores. We cannot recommend small scaler miners and artisanal miners to make this type of sluices. That is inefficient as it requires much energy, material will not be evenly spread and gold would be lost.
