Although these banded quartzites have proved auriferous, none of them have so far shown themselves to be payable; in the circumstance that these banded quartz rocks are a possible source of gold, they are identical with the quartzites of Peak Hill (to which reference has been made on an earlier page), and of Mount Margaret. The deposits of Bardoc have yielded 8,424ozs. of gold by the crushing of 11,710 tons of ore; being at the rate of 14dwts. per ton. This gold has been derived almost exclusively from quartz reefs of the first type. Our knowledge of the ore deposits in the more immediate vicinity of Broad Arrow is somewhat meagre. According to Mr. H. P. Woodward there are two principal lines of lode in the neighbourhood of Broad Arrow; the two which have a more or less North-Westerly trend are about a third of a mile apart. These, in all probability, are the Southerly continuation of some'of those lodes which have been mapped in the Bardoc neighbourhood. A good deal of prospecting seems to have been carried out in the search for deep leads in the vicinity of Bardoc. Despite the fact that some of the claims got good prospects, it is asserted that the true course of the lead had not been determined. Only 114ozs. of alluvial gold have been officially reported from the Broad Arrow Field for the year 1899. The following table gives the vield of the Broad Arrow Goldfield: --This comparatively small field, the most productive in Australia, embraces an area of 632 square miles; it is defined by the authorities as being: --Bounded by lines starting from a mile post on tho Eastern boundary of. the Coolgardie Goldfield, 40 miles Southerly f.
