By a late report of the Directors of the Burra Burra mine, it would appear, that they had made several successful attempts to smelt the ore, but, that the cost, having exceeded that of cartage to the port, and freight, the process has been abandoned. Parties, however, had offered to enter into an engagement to smelt the whole of the ore from the mine at about Swansea prices; notwithstanding the unfavourable circumstances under which such smelting would necessarily be carried on.
As I understand the nature of this arrangement, the ore will be smelted at the mine, and the remuneration to the smelter will be between fifty and sixty shillings per ton perhaps, by way of “return charges,” or we will say between sixty and seventy shillings, which is a sum exactly equal to the cartage of the ore to the port. If then the Directors abandoned their intentions, because they found they could not smelt at so low a sum as the price of cartage and freight, how will the contractor make it pay under more unfavourable circumstances? No doubt, if he should find it remunerative, the shareholders of the Burra Burra would find it still more so, and it would be the interest of the proprietors of the larger mines to enter into similar engagements; but, on a due consideration of this important subject, I am led to believe that to make smelting works successful in South Australia, Companies must purchase the ore, and carry it off to localities suitable for the operation. Such an arrangement would still considerably increase the profits to the proprietors of the mine, nor would there be any difficulty in determining the value of the ore, by processes similar to those adopted at Swansea, by which the interests of both parties are equally protected.
In the South Australian Register of the 27th of November of last year, it is stated that a Mr. Hunt, one of the auctioneers in Sydney, offered for sale thirteen tons of pure copper ore of colonial manufacture, from ore the produce of the Burra Burra, in ingots weighing 80 lbs. each; the ore having been smelted by Mr. James at Mr. Smith’s foundry at Newtown. This copper was however bought in at 80 pounds, the limit being 85 pounds per ton.
It will give the reader some idea of the character of this prodigious mine, and of the profits arising from it, to know, that during the four months preceding the 23rd October, 1847, the directors declared and paid three dividends, amounting to 200 per cent. on the subscribed capital, and that the credits of the Association on the 30th September were 104,694 pounds 4 shillings 8 pence. The Burra Burra mine however is not the only one of importance. Several others have of late been discovered, and South Australia may be said to be a thriving country in every sense of the word, and one in which those profitable interests will rapidly increase.
