Ruins Of the Hampden Smelter (Kuridala, North West Queensland)

Copper was discovered at Kuridala in 1884 and the Hampden Mine commenced during the 1890s. A Melbourne syndicate took over operations in 1897 and with increasing development of the mine in 1905 - 1906 the Hampden Cloncurry Limited company was formed. The township was surveyed as Hampden in 1910 (later called Friezland, and finally Kuridala in 1916). The Hampden Smelter operated from 1911 to 1920 with World War I being a particularly prosperous time for the company. After the war, the operations and the township declined and the Hampden Cloncurry Limited company ceased to exist in 1928. Tribute mining and further exploration and testing of the ore body has continued from 1932 through to the present day.

 

The Kuridala Township and Hampden Smelter are located approximately 65km south of Cloncurry and 345m above sea level, on an open plain against a background of rugged but picturesque hills.

 

The Cloncurry copper fields were discovered by Ernest Henry in 1867 but lack of capital and transport combined with low base metal prices precluded any major development. However, rising prices, new discoveries in the region and the promise of a railway combined with an inflow of British capital stimulated development. Additionally, Melbourne based promoters eager to develop another base metal bonanza like Broken Hill led to a resurgence of interest, especially in the Hampden mines.

 

The copper deposits at Kuridala (initially named Hampden) were discovered by William McPhail and Robert Johnson on their pastoral lease, Eureka, in January 1884. The Hampden mine was held by Fred Gibson in the 1890s and acquired in 1897 by a Melbourne syndicate comprising the 'Broken Hillionaires' - William Orr, William Knox, and Herman Schlapp. They floated the Hampden Copper Mines N. L. with a capital of £100,000 in £100 shares of which 200 were fully paid up. With this capital, they commenced a prospecting and stockpiling program sending specimens to Dapto and Wallaroo for testing. Government Geologist, W.E. Cameron's report on the district in 1900 discouraged investors as he reported that few of the lodes, other than the Hampden Company's main lode at Kuridala, were worth working.

 

A world price rise in copper in 1905, combined with a government decision in 1906 to extend the Townsville railway from Richmond to Cloncurry, stimulated further development. The Hampden Cloncurry Copper Mines Limited was registered in Victoria in March 1906 to acquire the old company's mines. However, the company only had a working capital of £35,000 after distributing vendor's shares and buying the Duchess mines. During this period there were over 20 companies investing similarly on the Cloncurry field.

 

The township was surveyed by the Mines Department around 1910 and was first known as Hampden after the mines discovered in the 1880s. By 1912 it was called Friezland, however was officially renamed Kuridala in October 1916 to minimise confusion with another settlement in Queensland. The reason for this change was considered to be linked to German names being unpopular at the outbreak of World War I.

 

Hampden Cloncurry Copper Mines Limited and its competitor, Mount Elliott, formed a special company in 1908 to finance and construct the railway extension from Cloncurry through Malbon, to Kuridala, and Mount Elliott. The company reconstructed in July 1909 by increasing its capitalisation, and concluding arrangements for a debenture issue to be secured against its proposed smelters. Its smelters were not fired until March 1911 and over the next three years 85,266 tons of ore were treated with an initial dividend of £140,000 being declared in 1913. In one month in 1915 the Hampden Smelter produced 813 tons of copper, an Australian record at that time.

 

Concern over the dwindling reserves of high grade ore led to William Corbould, the general manager of Mount Elliott mines, negotiating an amalgamation with Hampden Cloncurry to halt the fierce rivalry. But the latter was uninterested having consolidated its prospects in 1911 by acquiring many promising mines in the region, and enlarging its smelters and erecting new converters. In 1913, following a fire in the Hampden Consol's mine, Corbould convinced his London directors to reopen negotiations for a joint venture in the northern section of the field which still awaited a railway. Although Corbould and Huntley, the Hampden Cloncurry general manager, inspected many properties, the proposal lapsed.

 

The railway reached the township by 1910. A sanitary system was installed in 1911, after a four month typhoid epidemic, and a hospital erected by 1913, run by Dr. Old. It was described as the best and most modern hospital in the northwest. At its height, the town supported six hotels, five stores, four billiard saloons, three dance halls, and a cinema, two ice works, and one aerated waters factory, and Chinese gardens along the creek. There were also drapers, fruiterer, butcher, baker, timber merchant, garage, four churches, police station, court house, post office, banks, and a school with up to 280 pupils. A cyclone in December 1918 damaged the town and wrecked part of the powerhouse and smelter.

 

A comprehensive description of the plant and operations of the Kuridala Hampden mines and smelters was given by the Cloncurry mining warden in the Queensland Government Mining Journal of the 14th of September 1912. Ore from other company-owned mines (Duchess, Happy Salmon, MacGregor, and Trekelano) was railed in via a 1.2km branch line to the reduction plant bins, while the heavy pyrites ore from the Hampden mines was separated at the main shaft into coarse and fine products and conveyed to separate 1,500 ton capacity bins over a standard gauge railway to the plant.

 

A central power plant was installed with three separate Dowson pressure gas plants powered by three tandem type Kynoch gas engines of 320hp and two duplex type Hornsby gas engines of 200hp. Two Swedish General Electric Company generators of 1,250kw and 56kw running at 460 volts, supplied electricity to the machines in the works, fitting shops and mine pumps. Electric light for the mine and works was supplied by a British Thompson-Houston generator of 42kw, running at 420 volts. The fuel used in the gas producers was bituminous coal, coke or charcoal, made locally in the retorts.

 

The reduction plant consisted of two water-jacket furnaces, 2.1m by 1m and 4.2m by 1m, with dust chambers and a 52m high steel stack. There were two electrically driven converter vessels, each 3.2m by 2.3m. The molten product ran into a 3.7m diameter forehearth, while the slag was drawn off into double ton slag pots, run to the dump over 3 foot gauge, 42lb steel rail tracks. The copper was delivered from the forehearth to the converters. A 1.06m gauge track ran under the converters and carried the copper mould cars to the cleaning and shipping shed, at the end of which was the siding for railing out the cakes of blister copper.

 

The war conferred four years of prosperity on the Cloncurry district despite marketing, transport, and labour difficulties. The Hampden Cloncurry Company declared liberal dividends during 1915 - 1918: £40,000, £140,000, £52,500 and £35,000 making a total disbursement since commencing operations of £437,500. Its smelters treated over a quarter of a million tons of ore in this period, averaging over 70,000 tons annually. The company built light railways to its mines (e.g. Wee MacGregor and Trekelano) to ensure regular ore supplies and to reduce transport costs. In order to improve its ore treatment, Hampden Cloncurry installed a concentration plant in 1917. In 1918 an Edwards furnace was erected to pre-roast fine sulphide concentrates from the mill before smelting.

 

The dropping of the copper price control by the British government in 1918 forced the company into difficulties. Smelting was postponed until September 1919 and the company lost heavily during the next season and had to rely on ores from the Trekelano mine. Its smelter treated 69,598 tons of ore in 1920, but the company was forced to halt all operations after the Commonwealth Bank withdrew funds on copper awaiting export.

 

Companies and mines turned to the Theodore Labor Government for assistance but they were unsympathetic to the companies, even though they alone had the capacity to revive the Cloncurry field. More negotiations for amalgamation occurred in 1925 but failed, and in 1926 Hampden Cloncurry offered its assets for sale by tender and Mount Elliott acquired them all except for the Trekelano mine. The company was de-listed in 1928.

 

The rise and decline of the township reflected the company's fortunes. In 1913 there were 1,500 people increasing to 2,000 by 1920, but by 1924 this had declined to 800. With the rise of Mount Isa, Kaiser's bakehouse, the hospital, courthouse, one ice works, and a picture theatre, moved there in 1923 followed by Boyds' Hampden Hotel (renamed the Argent) in 1924. Other buildings including the police residence and Clerk of Petty Sessions house were moved to Cloncurry.

 

In its nine years of smelting Hampden Cloncurry had been one of Australia's largest mining companies producing 50,800 tons of copper (compared with Mount Elliott's 27,000), 21,000 ounces of gold and 381,000 ounces of silver. A more permanent achievement was its part in creating the metal fabricating company, Metal Manufacturers Limited, of which it was one of the four founders in 1916. Much of the money which built their Port Kembla works into one of the country's largest manufacturers came from the now derelict smelters in north-west Queensland.

 

In 1942 Mount Isa Mines bought the Kuridala Smelters for £800 and used parts to construct a copper furnace which commenced operating in April 1943 in response to wartime demands. The Tunny family continued to live at Kuridala as tributers on the Hampden and Consol mines from 1932 until 1969 and worked the mines down to 15.25m. A post office operated until 1975 and the last inhabitant, Lizzy Belch, moved into Cloncurry about 1982.

 

Further exploration and testing of the Kuridala ore body has occurred from 1948 up until the present with activities being undertaking by Mount Isa Mines, Broken Hill South, Enterprise Exploration, Marshall and James Boyd, Australian Selection, Kennecott Exploration, Carpentaria Exploration, Metana Minerals, A.M. Metcalfe, Dampier Mining Co Ltd, Newmont Pty Ltd, Australian Anglo American, Era South Pacific Pty Ltd, CRA Exploration Pty Ltd, BHP Minerals Ltd, Metana Minerals and Matrix Metals Ltd.
