AURIFEROUS REEFS. 23 



Thus 3,597 tons of ore yielded 9,641 dwts. of gold, the yield per 

 ton of ore being, therefore, just under 2* 7 dwts., a figure which agrees 

 admirably with the results obtained during the recent investigations 

 and it is clear that with the methods at present available for the 

 treatment of low grade ores there is no hope of gold-mining in Wain£d 

 becoming remunerative.
