BREAK O'DAY CO
Heritage Inventory Description
The Break-o'-Day shaft cannot be found. The puddler, 8m in diameter, at the apex of the quartz wash heap, is in very poor condition. The central pillar is gone and the trench is only distinguishable by the thick grass cover. There are a couple of arms to the quartz wash heap running generally south and west of the puddler. These arms are 50m by 35m by 2m high, and 50m by 25m wide and 2m high. This site is quite disturbed and it is not possible to interpert the operation of this mine.

Break o'Day Co., south of Laidlaws party, Rokewood,
27.05.1895: a public company which was organised in 1865 to work some ground that had been partly worked over; this company agreed to pay £6000 for the right to mine, £2000 was paid in advance with the balance paid by bills maturing over two years, plus a royalty of 5% on gold obtained and a nominal rent if required; a company of 3000 shares on which each paid £1 with a liability of £9 each in addition; the company's legal office was at Scarsdale; they commenced by putting down bores about 300 feet apart (which were nearly useless), sinking a shaft and erecting a puddling machines; first prospects were worked off with a tub and cradle for a yield of 7 to 8 dwt per load; tunnels were then constructed through the shallow ground and work went on for many years regularily returning 5/- and 10/- dividends; although this company's mining paid so well its profits were not derived from very extensive operations or from expensive appliances; in 1867 its assets were £27,641; all the gold was coarse and nuggety; gold was found everywhere from the surface down to 40 feet, but particularily following a 'mullock bank'; this area must not have been mined very well because it was remined by tributers who sank numerous shallow shafts and found gold on top of the mullock bank and in crevises in the bedrock; other parties in this area also found many nuggets.
