The Lady Shenton Gold Mine is 500 metres south-west of Menzies. It is the original lease in the area. Leslie Robert Menzie and John McDonald, had been invited to visit another recently discovered deposit, later known as the Pioneer. They became lost when seeking water from a soak, and stumbled onto the Shenton Ridge. Here was an outcrop of quartz, rich in gold, surrounded by many nuggets.
They travelled back to Coolgardie and pegged two leases, the Lady Shenton and Florence. The Lady Shenton was named after Sir George Shenton, businessman, politician, first Perth Mayor, and also sponsor for the Perth syndicate Menzie and McDonald were prospecting for. McDonald died shortly after, and several years later Menzie was wood cutting at Peak Hill, so neither gained much from the mine, said to the richest on the Menzies field.
The history of the mine is a series of companies and syndicates busily engaged in extracting gold. A company was floated in Perth in 1895, with 160 000 capital, and by June 1896 a 20 head battery was operating. The company operated the mine until 1905, when somehow despite the riches of the mine, it went into liquidation. The main problem appears that a fault cut the main lode at the southern end, and they ran out of ore. It had distributed 120 000 pounds of dividends to shareholders.
Wauchope (surname) held a tribute then over the mine for thirteen months. Robert Falconer, who had managed the mine for the former company, then took over the mine himself for a 6000 pound purchase price in 1906. The plant had been sold separately. Falconer mined a parallel lode, but by 1914 had struck the same cross fault which had ended the ore in the main lode, and he abandoned the mine.
Davis and Collier (surnames) in 1915 took over the mine and put through a few crushings. In 1923, another syndicate was formed of Perth and Kalgoorlie shareholders. By the following year much machinery is being erected on the lease. Not a lot of mining was found.
The Lady Shenton Options Ltd sought to find the extension of the lode past the fault which had cut off the lode. When in 1934, they found more gold on the southern side, the Lady Shenton Gold Mine (1934) NL was formed, and plant installed. This entity continued until 1939 at the mine.
Across 1995 to 1997, Paddington Gold developed an open pit on oxide ore, with the material sent to its plant near Broad Arrow for processing. The Lady Shenton Gold Mine, was largely developed by local Western Australian funds, which was a rarity for historic gold mines here, which were often financed by London or Adelaide/Melbourne concerns. There is also a distinct lack of controversy, which does not make for the most interesting article, but it appears people were too busy making bag loads of money.
Historic underground production amounts to 185 000 tonnes of ore at 32.0 g/t yielding 190 332 ounces of gold. More recent open pit mining saw 314 000 tonnes at 2.62 g/t yielding 26 164 ounces. The remaining resource is 580 800 tonnes at 2.82 g/t yielding 26 164 ounces.
The deposit contains three distinct lodes. The main Shenton Lode plunges south-west, hosted within amphibolite rocks, as a quartz vein up to 2 metres thick, with a small halo. Pyrite and arsenopyrite is dominant with some galena and sphalerite. The other lodes are called Falconer and Big Babe.
The Falconer Lode dips south-west, and intersects the Lady Shenton Lode at depth. Big Babe has no old workings on it. It developed at the margin of a large porphyry unit. At least three generations of feldspar porphyry dykes intrude the amphibolite sequence. The Falconer Lode is hosted entirely within porphyry.
The alteration zone with the Lady Shenton Lode is prograde biotite, overprinted on chlorite. Sulphides include galena, sphalerite, pyrrhotite, and pyrite. Crocoite was known historically from the mine. Sericite is more important at the Falconer and Big Babe lodes, but the above sulphides are found in all three lodes.
