Great mod though a bit unbalanced: making money is way too easy this way because the rate at which you 'produce' gold is very high (and since it's an endless source there is also no limit to creating endless digging spots, dredges and shaking tables). Could you perhaps lower the rate at which either sediment is dug up or gold is produced from the shaking table? It would keep the mod interesting without taking away most of the challenge of the game!! :)
