84 GEOLOGICAL SURVEY OP ALABAMA 



contacts, where the micaization is usually centralized, 

 having not yet been opened up or reached. 



The freedom of the deposit from crustal movements, 

 is clearly shown by the regularity of all the revealed 

 measures, and is further evidenced by the quite unusual 

 absence of folding or pressure cracks in the mica crys- 

 tals, which in large measure show perfect forms of crys- 

 tallization. A limited amount of A-mica was taken out in 

 one pit only on and near the surface, but this defective 

 form of crystallization appears to be entirely confined to 

 this one small locality in the chute as opened up, lessen- 

 ing, and being practically replaced by flat-sheet crystals 

 at the bottom of the cut, a percentage of good flat sheet 

 being in fact recoverable from most of the A-form crys- 

 tals taken out. 



The mica recovered is an amber muscovite of unusually 

 high grade for such surface crystals, splitting well, gen- 

 erally clear sheet, and running in sizes already to 3 x 4 

 inches. 



Mining conditions for economic recovery are most fav- 

 orable, as the deposit is so readily understandable as to 

 be capable of a complete proving out of all necessary data 

 relative to the proper and most competent and economic 

 points and method of entry before opening up the mine, 

 and has an expectancy of dry mine workings to a consid- 

 erable depth, as well as of a recovery of sound crystals 

 of flat sheet almost from the surface. 



The property belongs to and is being developed by, the 

 Midland Mica Syndicate, of Minneapolis. Exhibit sam- 

 ples serial No. 121 are from this deposit. 



Jim F lemming Mine. The precise location of the Jim 

 Flemming mine could not be ascertained, but its 

 approximate location is in Section 24, Township 17 S., 

 Range 10 E. 



It is the property of Mr. Harry Vaughn, and was op- 

 ened up by Mr. Maddox about the year 1916. The de- 

 posit exploited lies high, on the summit of a flat or 

 slightly rolling ridge, at approximately an elevation of 

 1,000 tidal datum. 



It is marked on the outcrop by heavy masses of quartz 

 containing large hornblende crystals (which are scat-
