Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1873 edition. Excerpt: ...This is surrounded on all sides by higher ranges bearing the same general character. The shallow alluvial deposits were mostly worked out during 1868 and 1869, the reefs now affording the entire yield of gold. The auriferous area is confined to veins traversing a crystalline Diorite, or within a certain limit of its boundary with Devonian slates. This comprises an area of about 6 square miles, 1 mile wide by 6 miles long. The number of proved auriferous reefs approaches 200, though only a few of these are now worked with vigour. The following abstract shows the gross quantity of gold transferred by police escort from Gympie, from January, 1868, to December, 1872, inclusive: --Years. ozs. dwts. grs. 1868 84,792 13 7 1869 70,852 19 23 1870 44,159 16 2 1871 44,712 13 7 1872 48,964 0 0 During 1872 20,500 tons of quartz were crushed for the abovenoted yield of 48,964 ounces of gold. This gives an average of 2 ounces18 dwts. 13 grains per ton for the entire field--a very good average indeed. Very rich yields have been experienced lately in some of the mines of this district, notably in the case of the claims known as 7 and 8 South Monkland. In July, 1872, the fortunate claimholders obtained a smelted cake of gold weighing 4,028 ounces. In Novernber of the same year, 739 tons of stone yielded 5,800 ounces of the precious metal. Mr. Hacket's excellent map of the Gympie, here inserted, (Plate 19), shows the position and name of most of the reefs included in the auriferous area. Of these the Smithfield, Monkland, Lady Mary and New Zealand have been hitherto the most productive. The number of miners employed on this field during 1871, as given by the statistics, was 1,235; but, as capital is now being invested in the erection of pumping gear and...show more
