RED JASPER IN THE HEATHCOTIAN ROCKS, NEAR 
TOOLLEEN. 
(NO. I ON LOCALITY MAP.) 
By E. J. Dunn, F.G.S., Director, Geological Survey. 
In 1892 I delimited the Heathcote beds as far as Lake Corop, and in) 
the following year the plan was handed in. This plan, however, appears 
to have been lost. While surveying this area a remarkable occurrence of 
beautiful red jasper was discovered. The spot was re-visited lately, and 
some specimens secured. The full extent of this jasper outcrop has not 
been determined. The outcrop is 1 mile to the east of Toolleen, on the 
main road to Rushworth. The red rock can be traced for \ mile in 
length, and appears to be at least a chain in width; in some places it is 
much more. The jasper is associated with an ancient igneous rock that 
has decomposed into a most fertile deep red soil in which the vine would 
flourish. Beds of jasper, mostly yellow in colour, continue right to the 
top of the range. Further to the east, greenish-grey, red, yellow, and 
other coloured jaspers occur, but remain to be exploited. The quartz 
variety of cats-eye and epidote occur on this range, and there are other 
minerals of interest present. 
Quartz veins are plentiful in some places, and where veins of white 
quartz traverse the red jasper the stone is very handsome. 
These Heathcotian beds have proved highly mineralized in different 
localities. In them gold, copper, iron, and other metals and their ores 
have been found, but in this remarkable belt, stretching from South 
Heathcote to Lake Corop, little or no effort has been made to prospect for 
valuable metals and ores, although it presents very attractive features.

SOME GOLD MINES NEAR HEATHCOTE. 
(NO. 2 ON LOCALITY MAP.) 
By E. /. Dunn, F.G.S., Director, Geological Survey. 
Mundy Gully Mine. 
The Mundy Gully mine is situated in timbered ranges about 6 miles 
from South Heathcote, in a direction somewhat, to the east of south. 
The alluvial gullies a little further to the south, such as Surface and 
Little Surface gullies, have been extensively worked for alluvial gold. 
The former gully has been worked for over 2 miles in length. The mine 
is in a tract of auriferous country of Silurian age that extends for a mile 
further to the south, and is said to be traceable in a northerly direction, as 
far as South Heathcote, a total length of about 7 miles. At present the 
mine is being worked by a co-operative party of twelve, with very satis¬ 
factory results. The shaft is 240 feet deep. From the bottom level 
there is a cross-cut to the west. The sandstone and slate beds dip east 
for 30 feet from the shaft, where am eastern “ leg,’' 3 inches thick, occurs, 
dipping east at 80 deg. ; the pitch of the beds is 35 deg. south. At 66 feet 
westward from the shaft is centre-country, and at 102 feet to the west 
of the shaft is the western leg. The whole thickness of the countrv-rock
