Overview

Excerpt from Western Australia, Department of Mines: Report of the Northampton Mineral Field, 3rd March, 1908 In an open out near the old main shaft a shallow crosscut has been driven for about 20ft. In clayey material containing carbonate of lead. Mr. Archibald told me his trials of the stuff from this cross cut averaged 20 per cent. of lead car bonate. The ore extracted from the lode in the old days is said to have been mostly carbonate near the surface. In a small parallel lode found by the present owners close to the main one, however, galena came up nearly to the surface. The present owners have raised about 53 tons of marketable galena since starting, mostly from this small lode, which has shown 3in. To 12m. In width of galena. According to the testimony of men who formerly worked in the mine they expect to get a larger lode in the bottom of the old workings, with a payable strong vein of galena upwards of 2ft. Wide. The reason this mine was shut down is stated to have been because the other mines 111 the hands of the same owners had to be closed in 1878, partly, if not entirely, owing to the death of the principal owner, and it could not be kept on by itself. The present owners seem well satisfied with their chances of success. But at the time of my visit the lode could not be inspected underground, and I am unable to express any opinion on it further than that it is clear that the old workers must have had a fairly long shoot of ore in the main lode, and, judg ing from the tailings heaps, must have dressed a good deal of material. They seem to have had jigging machinery on the ground. The amount of dressed ore raised is not on record, as it was sent away without distinction from the rest of the output from the Geraldine mines.
