44 FLUOKSPAR DEPOSITS OF SOUTHERN ILLINOIS, [bill. t^-iS. 



Fairvieui mine. — The first discovery of fluorspar in i^lace and the 

 first atteni])t to mine it seem to have been made npon the property 

 now owned by the Fairview Fluorspar Company. There are several 

 veins on the property, and ore is reported to liave been discovered 

 in 1S42. Xo atlem])t seems to have be(Mi made to operate nntil 1862, 

 when the (Jood Hope shaft was starte(L From that year nntil 1874 

 the work was practically continuons, ih(> ore beino- smelted as well 

 as mined on the property. Thi'ee snccessive smelters w^ere l)nilt ; two 

 were destroyed by firi% and t]ie third was toi'n down abont fifteen 

 years ai>'o. TIic (hiiups of flnoi'sj^ar which accumulated durini>- these 

 years when the lead alone was of \a1ue were worked n}) and sold in 

 the years 18S!) and 1890. From bsi»l to 1895 the property was oper- 

 ated under lease by the owners of tlie Rosiclare mine, and a large 

 toniiati'c of s])ai" was disposc^d of. Tlie (lood Hope vein is now beinij 

 reopened, and in the course of the present snrvey a number of the 

 old slopes oi! this vein were visited. Since the reopening of the 

 mine had only begun at the time it was visited, the following notes 

 are based to some extent npon the jmV)lished descriptions of J. G. 

 Norwood "■ and S. F. Emmons '' and an unpublished report on the 

 projjerty made in 1884 by Messrs. Anton, Eilers and E. W. Eaymond 

 and courteously placed at the disjDOsal of the Snrvev by the present 

 manager, ]Mr. T. P. Bis] and. 



The (lOod Hope vein occui's along a fanlt trending N. 21° E. 

 and dip})ing 70° 30' NW. The hanging wall is composed at the 

 surface of a coarse sandstone showing no pebbles and I)elieved to 

 belong to the Chester. The foot Avail at the main shaft is the Tribune 

 liuK'stone. as determined by Mr. TTlrich. A short distance to the 

 southwest a sliaft near the sawmill shows the foot wall to consist of 

 a sandy shale similai' to that occurring normally some distance above 

 the Tril)une limestone. 44ns would point to a cross fault betweiMi 

 the two shafts with a downthrow to the south. 44ie downthrow of 

 the main fault is to the west. The amount of the displacement is un- 

 known, but is certainly 100 feet and prol)ably much more. 44ie 

 walls underground are marked by vei'tical striations near the main 

 shaft and in the north drifts. In the south drifts the striations are 

 at angles to the northeast. 4'he hanging wall is sandstone or very 

 sandy shale to a depth of 150 feet at least. The foot wall shows 

 limestone at the surface and again at 210 feet, but a considerable 

 portion of the wall between is nnbroken, and sandy material occnrs 

 at a depth of 30 feet. 



The underground workings show a clean, hard hanging wall. The 

 foot wall is usually less well defined and is broken by a series of
