REPORT OF THE DIRECTOR AND STATE GEOLOGIST 1902 1*121 



The ore occurs in beds which are constricted in places, forming 

 lens-shaped masses. The beds are tilted, and the ore is always 

 richest in the trough of the lenticular mass. The age of the rocks 

 I have not determined, though I think they are later than 

 Grenville. 



The Carney Ore Mining Co. of New York operates three shafts 

 ^4 of a mile east of Caledonia. The mines are managed by John- 

 son Bros., of Gouverneur. The output is 80 tons a day. The ore 

 grades from 48$ to 50$ Fe. 



A deposit of micaceous hematite was discovered in the public 

 road 3 miles east of Canton village. It has been opened and the 

 ore used for road metal. 



Hematite was found also on the George Cole farm, V/ 2 miles 

 northwest of High Falls. Also on the Grant Hastings farm, 

 y 2 mile west of the same village. 



A deposit of red hematite found on the Halley farm 2 miles 

 from High Falls was leased by M. W. Spalding, of Rensselaer 

 Falls. These ores all occur in rocks of the Grenville series. An 

 iron ore bed was opened during the past season on the Vander- 

 hoff farm, 2 miles south of Crary's Mills in the town of Pierre- 

 pont, by S. Vanderhoff. The ore contains 55$ of Fe. A shaft 

 has been sunk to a depth of 20 feet. 



Iron ore was discovered at Owl head G miles south of Malone. 

 The deposit has not been exploited. 



The Chateaugay Iron Mining Co. is said to be operating mines 

 on Upper Chateaugay lake. 



Lead 



Rossie and Macomb have in times past produced lead, but the 

 mines have not been worked in recent years. The lead ore occurs 

 in small veins in rocks (limestones and schists) of the Grenville 

 series. During the past summer lead ore was discovered near 

 the DePeyster-Macomb line, 4 miles east of Macomb village and 

 7 miles north of Gouverneur. The discovery revived interest in 

 lead mining. Preparations are being made by the Gouverneur 

 Garnet and Lead Mining Co. to exploit this vein.
