a From 300 level. 
b About two-fifths from 500 level and rest from upper workings. 
c Prom 500. 600, and 700 levels. Output for 2 months only. 
It is rather difficult to account for the low percentage of lead and 
the very small amount of copper in these assay returns, as the silver 
was probably associated with one or both of these metals.

-Plan of fourth level of the Genesee-Vanderbilt mine, showing method of prospecting 
for ore bodies with the diamond drill. 
The value of the ore, never high grade as a whole, fell off with 
increase of depth below the 300 level, depreciating rapidly below the 
500 level, and changing near the 700 level to large bodies of low-grade 
pyrite. 
Near the surface, in the old workings, the ore is said to have been 
oxidized and soft, changing to galena at about 100 feet in depth.
