Ordinary concentration would not be successful, and the most likely pro-cess of treatment would appear to be leaching. Experiments carried outby the Government Metallurgist show the suitability of the ore for leaching. There is, however, a certain amount of arsenic in the ore which compli-cates the problem, as it is a very undesirable impurity, and some smeltersrefuse to treat ores containing arsenic. As the Government Metallurgist points out, an abundant supply of wateris necessary for leaching, and as water is not abundant in the locality, pro-vision would have to be made for an adequate supply. Before any extensive method of treatment were decided upon, the amountof ore and the average grade to be expected should be determined to greateror less extent by some syste
