Antimony Ores

Antimony Ores.

Stibnite lodes were discovered in 1873 near the coast of Queen Charlotte Sound, Marlborough, and proved to contain from 51.12 to 69.40 per cent, of antimony, the matrix being quartz. Similar lodes have been known for many years in the Shotover district, at Hindon, at Waipori, in the Carrick Mountains, and other places in Otago.

A sulphide-of-antimony lode occurs some miles south of Colling, wood, containing no less than .757 per cent, of silver, which is equal to 185.88 troy ounces per ton.

Besides these localities antimony ores are found at the Thames and at Reefton, associated with gold; and also at Langdon's Reef, near Greymouth.

At Endeavour Inlet, Cook Strait, antimony ore has been regularly mined, and is now being shipped to England. Arrangements are being made for the erection of smelting furnaces near the lodes.

In 1883 a bonus of £500 was offered for the production of the first 250 tons of antimony regulus to be sold in a foreign market at a fair market price, but no application was made for it, and it lapsed.
