The Union lode has proved to be a most valuable gold producer, and 
its present features imply permanence in depth. It has already been 
worked for § mile in length, and this legnth may be greatly extended by 
prospecting. Only a very short length of the lode has been worked below 
the 300-feet level. The distance from Melbourne is only 16 miles. 
It is intended to sink the main shaft below the 500-feet level, and to 
work the mine on a more extended scale. As the underlie is about 45 deg. 
to the east, the shaft would have been better placed if sunk further in that 
direction. 
Sections of the lode are as under: —

By E. /. Dunn, F.G.S., Director, Geological Survey. 
This lode is about 4 miles S. 20 deg. E. from Buchan, on the 
southern side of Back Creek. The country rock is limestone of Lower 
Devonian age. In strike and dip the lode seems, to conform with the strati¬ 
fication of the limestone. The strike of the lode is S. 25 E., and it dips 
32 degrees westerly. The outcrop on the surface appears to have been 
well marked for 4 or 5 chains. Two shafts have been sunk on the lode, 
but their depth is not known. From the surface downwards the lode was
