pitktrl :iiu sometimes present. Massive stibnite occurs in seveial of 

 these reefs, especially those situated on the west and north-^\e8t sides 

 of the iliorite. Calcite is a fairly common gangue mineral. The 

 gohl is of a high degree of fineness, as is usual elsewhere in Vic- 

 toria, where stibnite is the predominate vein sulphide, and is 

 generally valued at more than £1 an ounce. Neaily all these reefs 

 strike between north and north-east, and dip at steep angles. An 

 approximate estimate of the gold recorded from Yow Yow may he 

 stated as 8000 ozs., of which total, more than one-third (about 

 2700 ozs.) has been recorded from Allen's reef. The Eureka was 

 also an important contributor, and over 1500 ozs. were won from 

 this line of reef. Certain of these auriferous veins, worked within 

 the diorite, pass out into the sediments, and have been found to 

 be payably auriferous for some distance from the intrusion. 



E. — Alluvial. 

 The bulk of the alluvial gold from this field came from the creeks, 

 draining One Tree Hill; and, compared \\^th the gold oljtained 

 fiom them, other returns are unimportant. The gold was almost 

 invariably of the nuggety type, and one nugget of 103| ozs. was un- 

 earthed in Cobbler's Gully. The occurrence is of interest, since 

 elsewhere in Victoria large nuggets are generally associated with 

 Ordovician strata, and nuggets of over 100 ozs. have been recorded 

 in only two other areas — namely, Alexandra, and Wood's Point. i 

 where undoubted silurian sediments are the country rock. The 

 following is a list, proVjably not complete, of nuggets recorded from 

 the alluvial near One Tree Hill : —
