THE ADIRONDACK GRAPHITE DEPOSITS /I 



Milling practice. The mill had a daily capacity of 3000 pounds 

 of graphite. The ore was loaded into side-dumping cars which were 

 hauled up an inclined track into the mill. There the ore was 

 crushed, passed under a battery of ten California stamps, treated 

 with water and fed to the buddies, following the usual Adirondack 

 practice. The concentrates were hauled to Ticonderoga for 

 shipment. 



The mill has been torn down, and all the valuable material has 

 been removed. It is difficult to express an opinion about the value 

 of this property, but until the faults are carefully investigated and 

 understood it would not be possible to state whether or not the ore 

 is entirely exhausted. 



Hooper Brothers' Property 



Location. This recently developed property is located in the 

 township of Dresden, Washington county, on the west side of South 

 bay of Lake Champlain about 4 miles due west of Whitehall. Active 

 mining operations commenced in April 1916. The establishment 

 includes a mill, office, boarding house, blacksmith shop, etc. 



Geology. In many ways the conditions that obtain here are very 

 similar to those found on the Dixon and Faxon properties. It is 

 quite clear that the graphite-bearing rock is the same stratum being 

 worked at the town of Graphite. 



On approaching the mill, passing the extensive tailing pond, 

 which has been created by damming a swamp, one finds the Potsdam 

 sandstone, a rock of Upper Cambrian age, 2 in sharp contact upon 

 the yellow quartzite of the Grenville series. The mill is situated 

 directly upon this quartzite schist which splits easily into slabs. 

 However, this is not a pure rock but a syntectic of two. The 

 Laurentian granite has soaked it, " lit-par-lit " injected it, so it 

 would not be readily recognized as the equivalent of the Swede 

 Pond quartzite. It is only rarely that an exposure can be found 

 that reveals the original quartzite free from granitic material. 



The syntectic Swede Pond gneiss directly overlies the ore, the 

 Faxon limestone being absent. The graphite rock is the typical Dixon 

 schist; a quartz-feldspar-schist with 5 to 6 per cent of graphite, 

 exposed along the north road 1 and is found to outcrop for a long 

 distance along the strike at the base of a steep cliff (cuesta front). 



Beneath the ore is the rock that has been referred to as the Hague 

 gneiss, but the garnet is not so well developed and the sillimanite 



Constructed in colonial days by General Burgoynejas a military road. 

 2 Possibly of "Ozarkian " age.
