Of all the o'old mines roimd JohaniieslDuro- the 

 Robinson mine is the most remarkable for its size 

 both in respect of area and capital invested, for 

 the high average richness of its ore, for the enter- 

 jDrise and method of its management. This mine 

 was originall}^ bonglit by a small svnclicate for 

 less than 20,000/. In 1888, a company was 

 formed to work it, with a capital of 2,700,000/. 

 The company possesses a " myn pacht," or mining- 

 lease, of about 200 acres, containing some sixty 

 mining claims. Three distinct reefs are beinir 

 worked at different levels, the main reef leader, 

 the middle reef, and the south reef. The latter 

 has hitherto afforded the richest results. The 

 deepest level now being developed is about 500 

 feet below the surface, and it has been found by 

 assay, l^ut not yet confirmed by practical crushing, 

 that the ore at this depth maintains its richness. 

 There are about five miles of underground 

 workings, mostly illuminated by the electric light.
