much, gold was obtained from the inferior grade quartz, wliich 

 aveiaged 4 ozs. to the ton. at 65 ft. The brilliance of the Swedish 

 reef was short-lived, and, after 1870, little more was heard of it. 



C— Panto/) Hills (Orayn's Reef). 



As previously mentioned, productive quartz mining at Panton 

 Hills has lieen almost entirely confined to one line of reef — namely, 

 Oram's. This reef was first opened up during 1859. and it yielded' 

 fairly consistently until 1885. After this isolated rich yields were 

 obtained, mostly from the ground previously worked over. The 

 reef outcrops on the east side of the main road from Kangaroo- 

 Grounds to Queenstown and Kinglake. It strikes approximately 

 N 250 E_ and dips to west. Its width varies from two inches to- 

 three feet, and it fconsists of laminated white quartz, rarely crystal- 

 line. Oram's reef has been developed to a depth of nearly 400 ft.. 

 and longitudinally for a distance of about half a mile, and has 

 yielded approximately 9000 ozs. of gold ; more than 8000 ozs. of 

 which were obtained between the years 1865 and 1885. No gradual 

 change, and certainly no decrease in values, occur in depth, as is; 

 evident from the following table compiled from returns recorded 

 in the Mining Surveyor's Reports between 1866 and 1885. Only 

 those returns were used which gave the depth from which the ore- 

 was obtained.
