Not illustrated. 1905 Excerpt: ...chains south of " Bantam." ii. The shaft is 230 feet deep. From it a drive extends 20 feet to the north; then the ground east and south-east of the shaft has been stoped out to Heuat's boundary about 20 feet distant; and a stope extends 50 feet south and 120 feet south-west. iii. When the shaft was first sunk 100 gallons of water per day had to be raised, but the amount gradually diminished till now only a slight seepage at intervals can be detected in the cement. Cracks in the cement were sometimes found to act as reservoirs, but soon ran dry. iv. The sinking from 175 feet to 226 feet was in coarse conglomerate, and below in the fine conglomerate now worked. The wash is poor when made up of fine gravel, as at the shaft and in the northern drive (where the wash is auriferous only on bedrock, and when containing a few large pebbles). In the present face on the south-west the wash is well waterworn, with much rounded quartz--a good sign in this claim. It is hard and stained reddish, but north-eastwards it changes rather abruptly (25 feet from the shaft) to the ordinary blue cement. The run of gold, which is taken as about 20 feet wide, is trending somewhat south of west. Beneath the wash from 18 inches to 2 feet of barren schist-tish fills depressions in the bottom, especially south of the shaft. "Partings" (slickensides) occur over limited areas both in the wash and on and in bedrock, and in one case above the tish, but the gold is not richer in their vicinity than elsewhere. In the southern face, 35 feet from the shaft, there are greenish "heads " (fissure planes) 6 inches to 1 foot above bottom. There is, however, no gold above them, and little below. The slope of bottom is slight (1 in 20), and is outwards from the shaft, whi...
