ALABAMA MICA DEPOSITS 65, 



Very little of the mica recovered from these opera- 

 tions came from the two easterly shafts, most of it having 

 been taken as stated from the central shaft. The total 

 output, the amount of which could not be ascertained, 

 was said to be represented by about 12 tons of crude mine- 

 run mica stored in Mr. Pat Ayers' barn, which was ex- 

 amined and is represented by exhibit sample serial No. 

 113. 



Liberty Mica Mine. The Liberty mica mine is located 

 in the S. W. *4 of the N. E. % of Section 1, Township 

 18 S., Range 10 E., being about 1/2 niile S. W. of Mica- 

 ville, and % mile S. of the Cleburne county line. 



It is understood to be owned and operated by the Lib- 

 erty Mica Company. Considerable development work 

 was done on this property during 1919-1920, but work 

 was practically discontinued during the last half of 1920. 



The original opening up of the mine prior to present 

 ownership was by an open cut along the outcrop about 

 100 feet in length, in which cut the mica was crudely 

 won by stoping down on the pegmatite some 20 or 30 feet 

 at points most obviously micaized. Recoveries in these 

 earlier operations were largely if not altogether of A- 

 f ormed mica, of therefore inferior non-sheet grade, which 

 is characteristic of the deposit near the surface. Observ- 

 ing the change to more perfect forms of crystallization in 

 the mica blocks at lower levels, present operators later 

 on opened the mine by means of shafts and by a subse- 

 quent and final slope operation as shown in Figure 4. 



In all, five shafts have been sunk, in the relative posi- 

 tions shown on the general plan of the mine, to intersect 

 the pegmatite at various levels. 



The pegmatite body entered, has on the outcrop an 

 apparent strike of about 50 N.E.-S.W. and a dip S.E. of 

 40-45. 



The main working shaft D., is 35 ft. in depth, with a 

 horizontal entry running N. at the bottom for a distance 

 of about 40 feet. From this entry the S. stope or work- 

 ing heading, 60 feet in length E., and the N. heading, 

 35 feet in length E., were driven down on the dip of the 

 ore body. From these workings, the larger part of the 

 mica recovered in the mine has been taken out. Subse-
