A considerable amount of ore has been stoped above No. 3 

 level and between No. 3 and No. 7 levels ; but below the latter 

 no ore has been taken out. The ore stoped was milled by the old 

 Alpha Company ; but I have no reliable figures dealing with these 

 crushings ; judging, however, by the results of sampling, the mill 

 returns must have been remarkably poor. 



The number of samples taken was 174: the results of their assay 

 are summarized^ the following table, a complete return of the assays 

 being given in the appendix to this report: —

The average of the whole 174 samples works out at i*6 dwts. of 

 fine gold per ton for an average width of 4*3 feet. These results of 

 course show the ore to be absolutely unpayable. An inspection of 

 the list of assays or of the assay-plan discloses the fact that the bulk 

 of the quartz contains very little gold. A few samples only indicate
