72 GEOLOGICAL SURVEY OF ALABAMA 



Development work so far has been directed toward as- 

 certaining the form, character, and precise location of the 

 pegmatite dykes, of which there are several carried in the 

 hill where the mine proper will be opened up. 



Topographically, this hill or section of a ridge is of N. 

 to S. extension, rising some 70 to 90 feet above neigh- 

 boring branch or creek level. 



It is crossed near its northerly end by two and prob- 

 ably three pegmatite dykes, striking about N.70W., and 

 dipping S., at angles not yet fully determined. 



Country rock measures on the contrary, near and on 

 the surface, appear to carry the average ruling N.E.-S.W. 

 strike of the district, indicating a cross formation ; which 

 condition appears to be closely paralleled also on the Ed- 

 wards property immediately N. of it, and previously de- 

 scribed, as also may be the case if the facts were ascer- 

 tainable in the Great Southern mine. 



Considerable old mining has been done on the property 

 both for mica and for kaolin, presumably by or for the 

 Alabama Kaolin Company about the year 1888, evidenced 

 by an old shaft originally 40 ft. deep but milled in about 

 10 feet, also by a surface cut some eight to 10 feet deep, 

 said to have been opened up principally for kaolin, sam- 

 ples of which clay were among those tested favorably 

 for porcelain manufacture by Trenton potteries. Some 

 of the largest and best mica ever recovered in the 

 Micaville district are stated by Mr. Pat Ayres to have 

 been taken out of this old shaft, which is now being tim- 

 bered up preparatory to re-entry of the old underground 

 mine workings. Preparatory to this development, the old 

 cut next to the outcrop was cleaned out and lengthened 

 along its N. E. strike, an included quartz horse being 

 taken out with recovery of some 1,600 pounds of flat mica 

 in small sizes next the upper contact and around the 

 quartz horse. The old working shaft now being re-open- 

 ed lying at the proper distance south of this outcrop 

 tested, is correctly placed to reach this pegmatite body 

 and develop it at proper levels. Water level is indicated 

 at approximately 70 feet. 



On the central pegmatite dyke, at a point about 200 

 feet N. of the old working mine shaft, a surface outcrop
