since. The Coal Hill vein outcrops on the face and top of a fiat 

 knob of gneiss and occupies a vertical fissure from 2 to 6 feet wide 

 within a parallel zone of brecciated rock. The strike is north 80° 

 west. The galena occurs in disseminated particles and in larger 

 masses within calcite gangue. The lead ore is accompanied by 

 minor amounts of chalcopyrite, sphalerite and pyrite and a little 

 fiuorite. The wall rock consists of a gray gneiss which has been 

 intruded by red granite. 



The Victoria mine, also known as the Pardee mine, lies i| miles 

 south of Rossie and about i mile northeast of the Coal Hill mine. 

 Its situation is similar, the vein being exposed along the side and 

 dip of a low ridge of grayish, more or less granitized gneiss. The 

 strike is a little north of west and the dip approximately vertical. 

 It was opened about the same time as the Coal Hill property. A 

 vertical shaft was put down at the base of the hill reaching a reported 

 depth of 300 feet and other shafts were sunk on top of the ridge. 

 The vein ranges from 2 to 4 feet in width and is composed of calcite 

 carrying some galena and minor amounts of sphalerite, chalcopyrite, 

 pyrite and green fluorite. Considerable brecciation has occurred 

 along the fissure and stringers of the material make off into walls 

 for short distances. The country rock on the outcrop of the vein 

 is an injected gneiss but it would appear likely that limestone was 

 encountered in depth since there are large blocks of this material 

 on the spoil bank. A separating works and smelter were erected on 

 the property to treat the ore of the mine. The output of metallic 

 lead is not known. 



Another place where mining for lead was carried on in the middle 

 years of the last century is at Mineral Point on Black lake, town 

 of Macomb. The deposit is said to have been discovered about 

 1836 and 3 years later a company known as the Mineral Point Lead 

 Manufacturing Co. was organized to work the deposit. Very little 

 is known about the outcome of these early operations. In the 

 sixties of the last century the property was leased by J. B. Morgan 

 who also for a time operated the Coal Hill property. The occurrence 

 is very similar in its features to the deposits in Rossie, the vein 

 occurring in gneiss and consisting of a small fissure filled with calcite 

 and carrying sulphides of lead, copper and iron. 



Another galena vein occurs on the farm of F. E. Turner, some 

 three miles north of Brasie Corners, town of Macomb. It measures 

 up to 2 or 3 feet in width and can be followed for 100 feet or more 

 along the edge of a limestone ridge. In places it carries abundant 

 galena with minor amounts of sphalerite and would be workable
