52 FLUOKSPAR DEPOSITS OF SOUTHERN ILLINOIS, [bull. 255. 



Il'tcl-s //line. — This is in the same section as the Baldwin and is 

 sii])i>()se(l to be on a continuation of that vein. A\lien visited it was 

 a prospect oii-ly, the fluorspar liaving been located by means of a 

 post-hole digger. A body of clear spar somewhat over 2 feet thick 

 Avas indicated. 



In another portion of the SE. ^ NW. ^ sec. 23 two small open 

 cuts show tlie presence of a 3-inch vein of purple spar, with consider- 

 able calcite, cutting across the Ste. Genevieve limestone with a course 

 N. 20° E. Slickensides indicate some faulting, and the downthrow 

 is apparent^ to the west. 



IIa//ij} //il/ie. — On the northeast flank of the Hicks dome is a second 

 group of prospects, of which the Hamp mine is the most important 

 vet tleveloped. This mine is on a well-developed fissure cutting the 

 Ste. Genevieve limestone with a course X. G0° E. There seems to 

 have been very little displacement, since the Kosiclare sandstone 

 member of the formation occurs at nearly the same elevation on both 

 sides. The vein dips SE. (')S° and crosses the beds on both dip and 

 strike, the dip of the strata being 10° NW. The vein consists of very 

 clean '' ribbon " fluorspar, mainly white in color, but with some 

 purple near the surface. There is very little calcite developed with 

 it. Some gal(>na is found and very subordinate amounts of blende. 

 The property is l)eing developed by two shafts, the deeper being at 

 last accounts (U feet down, and showing at the bottom G feet of clear 

 white fluorh})ar. 



East of the Hamp mine there are a number of small prospects 

 showing spar, as indicated on the map. None of these have been 

 developed enough to make clear the relations of the ore bodies. 

 Northwest of the area also (sec. 11, T. 11 S., R. T E.), on the Wright 

 land, some prospecting has been done in an area of complexly 

 faulted and slightly folded rocks. 



SCATTERED 3I1NES IN HARDIN COUNTY. 



General state/zient. — At a number of points throughout the county 

 and outside of the areas specially mapped there are occurrences of 

 spar and lead, and at a few places some mining has been carried on. 

 As many of these places as possible were visited in 1903, and brief 

 notes on a number of them are given below. The largest number 

 of these mines is near Eichorn. which is located in sec. 11, T. 12 S., 

 R. 7 E. The Pell. Stewart, Cook, Oxford and Watson, Parkenson, 

 and Gordon are in this vicinity, the two last named being in Pope 

 County. At Lead Hill, north of Cave in Rock, mining has also been 

 carried on at a number of points. In the country back of Lead Hill, 

 extending to Rock Creek, are a number of prospects, including the 

 Showalter, Patton, and a second Eureka. This enumeration does 

 not exhaust the list, but includes most of those personally visited.
