He also states that it would be quite possible to commence work on the property immediately by ground sluicing; but he is strongly of opinion that this policy would be unwise, as the disturbance of the ground might tend to interfere with the economical working on a large scale such as is proposed. Provided no unforeseen difficulties arise, Mr. Laws is of opinion that the whole of the plant would be in operation within nine months. If Mr. Laws’ advice is taken, he estimates that working cost would amount to about £10 per ton on ore of the value already found, but, as stated above, to allow for working a larger quantity of lower grade ground, working costs should be placed at £15 per ton of ore. The price of the ore in the market at Liverpool may be taken at £90 per ton, which, after deducting £15 for working costs, and £30 per ton for transport and contingencies, would leave a margin of profit of £45 per ton of ore. Although it is proposed in the earlier stages of development to equip the mine with plant capable of producing 800 tons annually, any increase on this rate of working will depend on surveys determining the head of water available.
