mixed with and replaced by the ore, present strong evidence of the 
replacement of an interbedded, irregular lens or streak of crystalline 
limestone. 
There are, roughly estimated, some 7000 tons of rock on the dump ; 
much of it is magnetiferous and could be readily concentrated by 
magnetic methods, so that possibly 2000 tons of magnetite might be 
recovered. 
Two or 3 years ago an unsuccessful attempt was made to locate 
the faulted-off portion of the ore (see fig. 13). Three diamond 
drill holes were put down at various angles without encountering 
the ore, and the work was then abandoned; since that time nothing 
further has been done. The writer believes that a properly directed 
drilling campaign would prove successful in locating the faulted 
body, and in view of the quality of the ore, such exploratory work 
would seem to be justified.
