Our First Half-Century: A Review of Queensland Progress Based Upon Official Information

by Queensland

In its thirty-six years of existence Charters Towers has turned out over 5,800,000 ounces—more than £24,600,000 worth of gold; last year's output was of the value of £700,000; and to-day the indications in the deeper ground of the field are such that there is reason to expect that both the term of its existence and the volume of its output will be greatly extended. At Mount Morgan—the show mine of Queensland, and one of the greatest in the world—there has been quarried out of the hill and dug from the depths beneath stone that, under treatment by works in every way worthy of such a mine, has, in a little over twenty-two years, yielded gold to the value of over £13,760,000; has paid in wages and other expenditure about £7,000,000; and has given to the fortunate holders of its 1,000,000 shares some £7,230,000 in dividends. That is what the big mine has done. What is it doing now? True, the phenomenal yields of gold and the high grade of its auriferous ores that characterised the earlier years of its history showed signs of diminishing as time went on; but diminishing yields were counterbalanced by improved methods of mining and treatment, with consequent reduction of costs; and a few years since copper as well as gold was found in the lower levels, with the result that the mine has become at once the most productive copper and the most productive gold mine of the State. It has already turned out copper to the value of about £1,500,000, which has to be added to the gold yield, given above, to arrive at its total product; while the value of the mine's aggregate output for 1908 (over £1,017,000) was greater, with perhaps one exception, than that of any previous year in its history.

Though for some years gold was the only string to the bow of Queensland's mining industry, that state of things has long since changed. In the early sixties copper was mined in the State, but then and for many years afterwards only to a limited extent. Tin came on the scene in 1872. During the first forty years of Queensland's existence the gold won within her borders was four times the worth of all other minerals and coal produced; but so rapid has been the increase during the past ten years in the production of the industrial metals—or "other minerals," as they are officially termed, to distinguish them from gold—that in 1907 their value exceeded that of the gold yield by over £170,000. Indeed, during the five years ending with that year there was an almost phenomenal expansion. The output of 1902 was of the value of only £589,960. In the following year it increased to £846,280, and then for four years jumped up by leaps and bounds, until in 1907 the yield was worth no less than £2,153,226.

The known mineral-producing country of Queensland extends over an immense area. It begins on the southern border, where the Silver Spur mine maintains a constant output of silver and other mineral products, and where the Stanthorpe district, our first stanniferous field, still materially assists, with the aid of dredges, in the tin production of the State; and extends northerly a hundred miles beyond the goldfield of Coen, in the Cape York Peninsula. Over this immense distance of some 1,300 miles from south to north, and extending inland from 50 to 200 miles from the eastern coast, are located at varying intervals fields producing gold, silver, copper, tin, coal, lead, sapphires, manganese, wolfram, molybdenite, bismuth, and graphite; while further to the west are the opal fields of Jundah, Opalton, and Kynuna, the copper deposits of the vast Cloncurry district, the silver-lead mines of Lawn Hills in the Burketown district, and the Croydon goldfield, also on the Gulf waters. Queensland, with a huge area of 670,500 square miles and a scant population of little more than half a million of people, has a hundred proclaimed gold, mineral, and coal fields, having a combined area of about 50,000,000 acres.

Apart from goldfields, by far the most important and productive of these areas is the tract of country which forms the hinterland of the port of Cairns—a tract which includes the tin-mining centres of Herberton, Stannary Hills, Irvinebank, Nymbool, and Reid's Creek; the copper and silver-lead mines of Chillagoe and Mungana; the copper mines of Mount Molloy and O.K.; the wolfram, molybdenite, and bismuth mines of Wolfram Camp, Bamford, and Mount Carbine; and the antimony deposits of the Mitchell River. The two large mineral fields into which this portion of the State is now officially divided—Chillagoe and Herberton—have together an area of over 8,500,000 acres. The port of Cairns was not established till 1876—seventeen years after the foundation of the State. Now there yearly pass through it from the area mentioned minerals worth from £600,000 to £800,000, exclusive of the mineral product from the Etheridge and Croydon fields, which also, for the most part, finds an outlet through the same channel. Copper and tin are responsible for more than half the amount named, but the potentialities of the district as far as other minerals are concerned are almost unlimited. Of wolfram—taking only one example—this part of the State alone can supply the world's demand, and have a good deal to spare afterwards. The Queensland Government Geologist has estimated that the wolfram-bearing country in this portion of Queensland extends over an area of 3,500 square miles. Given anything like a permanent demand and a fair and steady market, wolfram production would soon take a prominent position in our mining industry. The historical tin mine of the district is the Vulcan, at Irvinebank, which has attained the greatest depth (1,450 feet) reached by any tin mine in Queensland, and where the appliances for recovering the metal are more up-to-date than at Dolcoath, the most famous tin mine of Cornwall. During the twenty-five years of its existence, the Vulcan Mine has from 106,000 tons of tin ore produced over 9,790 tons of concentrates, worth something approaching £500,000, and has paid its lucky shareholders dividends to the extent of £160,000. The opening up of this large and prolific district is largely due to the enterprise of the Chillagoe Company, which not only has developed extensively its several mines and erected large ore-treatment works, but has built the railway—in length 93 miles—which connects those mines and numerous others with the Government railway at the top of the Coastal Range at Mareeba, and is building a further extension to the Etheridge field, nearly 150 miles further inland.

Queensland is known as a country of magnificent distances, and one example of its vast expanse is the extent of the copper area of the Cloncurry district, which is tapped by the Great Northern Railway 480 miles westward from the port of Townsville. This district is by far the largest tract of copper-bearing country in Australia, and one of the largest in the world. As the crow flies, it extends north and south for more than 150 miles, and east and west some 80 or 100 miles. Over this large area, covering at least 15,000 square miles, copper has been proved to exist. At the close of 1907 there were on the Warden's books over 800 mineral leases, besides some hundreds of claims and several freeholds. The outcrops throughout the district have been described by one of the Government Geologists as innumerable and phenomenally rich. But the district is still in the prospecting stage, and it is yet too soon to pronounce an opinion as to whether the deposits generally will live at depth, or of what value they will be if they do, although it may safely be said that the developments in the more important mines during the past twelve months have been distinctly encouraging. Smelting operations are already in progress at two, if not three, of the principal mining centres of the district, and a railway extension from Cloncurry 74 miles southward is now in course of construction. Another Queensland mineral field of vast extent is the Etheridge. It has an area equal to half that of Scotland, and the Warden for the field, when he undertakes his periodical patrol, has an itinerary of about 400 miles.

CHARTERS TOWERS: PLANT'S DAY DAWN

Passing reference has been made to the sapphire field of Anakie, in Central Queensland, and to the opal to be found in her trackless West. As a matter of fact, isolated finds of many kinds of gems besides these two have been made in widely separated parts of the State, but as a recognised branch of the mining industry opal and sapphire mining has for years occupied an important place. In the Anakie field, 190 miles from Rockhampton, on the Central Railway, the existence of gem-stones was officially reported as early as 1892. Ten years later the Government Geologist, reporting on these sapphire fields, stated that "the total distance along which deposits are found ... is altogether about fifteen miles. Of an area of 400 square miles examined, fifty square miles contain deposits carrying sapphires of more or less value." In 1905, another member of the Geological staff reported that the most important recent development had been the opening up of a second bed of the sapphire wash at a depth of 25 feet, and that excellent stones, freer from flaws than those nearer the surface, were being obtained from the lower deposit. Mining for these precious stones, many of which are of the most beautiful description, has been to a considerable extent detrimentally affected by the difficulty experienced in getting a regular market and what is considered a fair price for the gems; but, notwithstanding this drawback, there was a large expansion in the industry during the four years preceding 1907—the annual production having increased in that period from £7,000 to £35,000 in value. In 1908, however, there was a considerable falling off, mainly because miners were not satisfied with the prices obtainable; but, with an improvement in this respect, renewed activity on the field, which even now supports a population of over 1,000 persons, may be looked for.

The opal-bearing country extends over a much wider area than sapphires. The width of this country is, roughly, about 250 miles, while in length it extends right from the New South Wales border half-way up the State in a curve bending towards the South Australian border. The chief centres of production have been Kynuna (near Winton), Opalton and Fermoy (in the Longreach district), Eromanga, and Yowah (near Thargomindah). The Queensland opal is recognised as being unsurpassed for its brilliance and iridescence, and there is reason to believe that much more will be found than has yet been unearthed; but the quest for it is difficult owing to the arid nature and vast extent of the western plains where it occurs. In good seasons men in those regions find ready employment on the pastoral stations; in very dry ones, they cannot prospect for the precious stone, and the result has been that the industry has fluctuated even more than that of sapphire mining. The highest point was attained in 1895, when the value of the opal product reached nearly £33,000. Of late years Queensland has been blessed with good seasons, and the uncertain occupation of opal mining has, with many men, given place to the more regular and more comfortable station life. While the opal, the sapphire, and other precious stones have been dug from Queensland's earth, her Northern waters have for years yielded the lustrous pearl, and in 1908 pearl-shell to the value of £71,000 was exported.

Sir William Ramsay, speaking as a scientific authority, lately stated that the day will come when Great Britain, if she continue to be dependent on her own coal supplies, will find it difficult not only to carry on her manufactures but to provide fuel for household purposes. Well, when that day does come, she can send to Queensland for what coal she wants. Here there are coal measures in abundance—in the South, Central, and Northern divisions of the State, and on the Darling Downs. True, we have not yet done much in the way of production, but all that is wanted is a market, and coal, both bituminous and anthracitic, can be dug out of the earth and sent away in practically unlimited quantities. Of ironstone, also, there is an abundance, and that, too, in such close proximity to the coal supplies that when the time arrives for Australia to enter earnestly into the enterprise of iron and steel manufacture Queensland should play an important part both in producing the raw material and in preparing the product for the market.
