Transactions. 



On the Burnt Range and Lammerlaw Range there are a number of small 

 veins or leaders, some carrying good gold. Their strike is for the most part 

 east and west, and they dip in either direction, with varying underhe. They 

 show similar characters to the O.P.Q. — namely, the occurrence of lenses 

 of quartz in the fissure-zone. The smaller veins, however, carry generally 

 a stronger and more continuous body of quartz than the larger. 



Waifori Antimony -vein. — This occurs on the right bank of Stony Creek, 

 nine miles above the township. It has a strike of 105°, and a northerly 

 dip of about 45°. The outcrop has been proved for half a mile. The vein 

 is from 3 ft. to 4 ft. wide, and consists of quartz seamed with mullock, and 

 poor in gold. It carries frequent bunches of quartzose stibnite. At one 

 spot a pocket of scheelite was found and extracted, and gypsum was found 

 where the scheelite and stibnite were intermingled. This is no doubt a 

 .secondary product, formed by the oxidation of sulphur and combination 

 with the lime of the scheelite. 



The veins at Gabriel's Gully, near Lawrence; at Table Hill, near Milton ; 

 and at Saddle Hill, near Dunedin, described by Ulrich in 1875, are now 

 all closed down. 



(7.) The Barewood Claim. 



This is the best-known vein in the Taieri Gorge district, which includes 

 several veins prospected at Hindon, Matarae, and elsewhere. 



The country rock is a quartz-mica-schist, lying almost horizontally. 

 The vein strikes north-west and south-east, and dips north-east at an angle 

 of about 60°. It is worked by an underlay shaft, which cuts the vein at a 

 depth of 130 ft. At 180 ft. and 240 ft. crosscuts open up Nos. 2 and 3 levels, 

 while a winze from No. 3 level has been sunk for a further distance of 30 ft. 

 This is one of the few veins now being worked on the goldfield. It averages 

 from 4 ft. to 5 ft. in width, but widens out to 15 ft. in the upper levels. It 

 is composed of solid quartz throughout, divided by subordinate clay heads 

 or partings parallel to the well-defined wails. The foot-wall is uninterrupted, 

 but the hanging-wall carries small leaders (from 6 in. to 12 in. wide), which 

 wedge out a short distance up. These leaders generally carry good gold.

Slickensides are often well developed, generally on the hanging-wall. In 

 places the quartz adjoining the walls, and also the adjacent wall-rock, are 

 highly brecciated. This has been seen on both walls in No. 3 level, and on 

 the hanging-wall in No. 1, while it is absent in No. 2. 



Horizontal Distribution of Gold. — The gold, so far as workings have 

 disclosed, is uniformly distributed along the strike, and shows as yet no 

 tendency to occur in localised shoots.
