vertical. The lode has copper pyrites sparsely disseminated and also in 
thin seams through it. Galena and iron pyrites also occur. A shaft has 
been sunk 45 feet. At the surface stains of green and blue carbonate of 
copper attracted attention, while lower down only sulphides occur. The 
shaft is in a gully, and in consequence the surface water is troublesome 
Insufficient work has been done to prove whether valuable ore exists or not. 
So far as worked, the ore is very poor. Ash beds of Lower Devonian age 
constitute the country rock, and at a short distance porphyry outcrops. 
South-east from the shaft the lode thickens out to 15 feet, and is very 
prominent on the hillside. At the shaft the lode is about 8 feet thick. 
The remains of an old vertical boiler and engine are at the shaft; the 
protecting shed was burnt by a bush fire.
