Government geologist A. Gibb-Maitland was inspecting mines in the Pilbara in 1907. He was staying in Roebourne at the end of the trip, awaiting the steamer to take him from Cossack to Perth the next day, when he was approached by a man named A.W.Clarke.
He was part of Clarkes Antimony-Gold Syndicate NL formed in Adelaide. Clarke showed Gibb-Maitland specimens from his mine of quartz with stibnite through it, and much gold, others of solid stibnite and its oxidised by-product cervantite.
The lease was 40 acres, the lode 12 feet wide. Very solid and pure stibnite, of a good quantity, in a short shoot, in a good sized reef, with two shafts, one to 25 feet and another 40 feet deep.
The vagueness is because Gibb-Maitland did not have time to inspect the mine, and information was purely what Clarke told him, who was interested in promoting his new business venture.
Despite getting a fairly accurate description of the location, the writer has been unable to locate the former mine, and goes down as another lost locality, until more information comes to hand. Simpson, later in his Minerals of Western Australia, Volume 3, states the site is on the north-west bank of the Sherlock River crossing, Roebourne to Croydon Road, at Coonanarrina Pool.
Stated as near the Roebourne to Croydon Station crossing of the Sherlock River, 39 miles from Roebourne, 24 miles from Balla Balla, 16 miles from the Croydon Station homestead, and 8 miles from the Sherlock Station homestead.
Clarke and the syndicate at least were real, which was formed in 1906, on the basis of Clarke's discovery. Stibnite assayed at 40%, gold 1-4 ounce to the tonne it was claimed. Clarke was in Adelaide beginning of August 1907 to promote the find to the syndicate's shareholders. One month later, the syndicate held a meeting in which they voted to voluntarily wind-up, no reason given.
A. Gibb Maitland later in 1919 states the mine is in greenstone at the foot of a plateau. It is quartz bearing antimony exposed in a series of shallow shafts, open cuts and trenches, two of the shafts down to 40 feet, and two to 25 feet, on a lode 12 feet wide. He calls it the Sherlock Antimony Mine at this time. Containing solid stibnite and cervantite. 10 tonnes was extracted producing 57% antimony and some gold, then in 1916 5 tonnes was shipped to Sydney.
