ALABAMA MICA DEPOSITS 85 



tered thickly over the ground in cultivated areas below 

 the outcrop), has a strike of N.50E., dipping about 40 

 S. E., and has been partially opened up along the strike 

 by test pits for a distance of several hundred feet. 



First developments stated to have been made by Mr. 

 Maddox was by means of a surface cut, 10 feet deep, of 

 E. and W. extension, intended as a cross-cut. In this cut 

 or pit, a very coarse pegmatite was exposed, made up of a 

 generally unaltered feldspar in large aggregate, inter- 

 bedded with masses of quartz containing numerous and 

 large hornblende crystals, the mica observed being in 

 fairly large crystals chiefly placed along the quartz con- 

 tacts, but to some extent carried in the feldspar, where 

 partially kaolinized. 



As examined in the cut the mica is a flat muscovite 

 of light amber color, in fair sizes, but tangle-sheet edged, 

 or not free splitting, the sheets being interfoliated with 

 a white incrustation. 



Subsequent development for systematic mining was 

 carried on by means of a slope, driven down in the peg- 

 matite body proper from its outcrop, at a point about 75 

 yards S. W. of the first described pit, and following the 

 dip S. E. 



The full width or thickness of the pegmatite, indicated 

 as 6 to 8 feet, was taken out in this slope entry, revealing 

 a top and bottom walling of red mica gneiss. 



At the 90 foot level, or the foot of the slope, a left 

 entry had been run out N. E. about 20 feet. The mica 

 recovered from the slope and entry ; estimated to be in all 

 about 6 to 8 tons, is at present stored in the mica house 

 precisely as taken out, and is run-of-mine, none of it hav- 

 ing been worked up or sheeted. It runs quite uniformly 

 as to size in 2x3 to 4x4 or larger blocks. 



From the number of crystals left in place along the 

 hanging wall contact, that contact seems to have been as 

 usual the heaviest mica concentration in the deposit. 



Exhibit sample serial No. 122 is drawn from the stock 

 house run-of-mine, on this property.
