ALABAMA MICA DEPOSITS 71 



Range 10 E., lying immediately W. of the Liberty mine. 

 It is owned and operated by the Consolidated Mica Co., 

 of South Bend, Indiana. 



The pegmatite dyke entered has a definite indicated 

 strike across the property of about 45 N.E.-S.W., dip- 

 ping 40-50 S.E. As far as developed, it lies in quite 

 regular conformity with the enclosing red mica gneiss, 

 and carries a fairly uniform width of about 10 to 12 feet. 



The pegmatite is made up of an aggregate of small 

 fragmentary quartz and feldspar, the latter being largely 

 kaolinized. The mica recovered had been, prior to the 

 examination, altogether in small sizes but of flat clear 

 sheet of good quality. 



The first shaft sunk, set off too far E., did not reach 

 the dyke at a depth of 20 feet, and was abandoned. It is 

 uniformly gneiss walled from top to bottom. Subsequent- 

 ly, two more shafts were sunk nearer to the outcrop, one 

 15, and the other 30 feet in depth, connected on the 15 foot 

 level by a crooked horizontal entry following and lying in 

 the pegmatite, the mica mined, recovered from these 

 workings, being hauled to the surface from the main 

 shaft by windlass and bucket. 



The operation thus far has been crude and in the na- 

 ture of a prospect, and has not been properly placed or 

 of sufficient extent or depth as yet to constitute any 

 proper proof of the mica reserves present or of their 

 character. Near the S. W. corner of the property, and 

 possibly on the S. W. extension of the dyke opened at the 

 mine, an outcrop of pegmatite shows up very plainly, 

 which near the surface is heavily micaized. It has been 

 driven into on the adjoining property a few feet only S. 

 of the property line, and large blocks of A-form mica 

 exposed in the contact next the hanging wall, bedded in 

 and on massive quartz. Exploitation of the pegmatite at 

 this point on the property owned, would be promising, and 

 could be easily and effectively done. 



Week's Mine. Location, the N. E. % of the N. W. % 

 of Section 7, Township 18 S., Range 11 E., near and S. E. 

 from and cornering with the Great Southern mine. The 

 mine is owned and is being opened up by the American 

 Mica Mining Co., of Minneapolis, Minn.
