The ore in appearance and composition is much Hke that from the 

 Mineville deposits. It is, however, lower in phosphorus than the 

 Old Bed product, with an iron content of from 63 to 65 per cent. 

 The shipments are reported by Smock to have amounted in all to 

 800,000 tons. 



Lake -Sanford. The property formerly owned by the Mcln- 

 tyre Iron Co., comprising over 100 square miles in western Essex 

 county within which the Lake Sanford titaniferous magnetite de- 

 posits are located, has been taken over by parties for the purpose of 

 exploration and development. The new company has been organ- 

 ized by Mr W. T. Foote, who is actively identified with its manage- 

 ment. It is to be known as the Tahawus Iron Ore Co. Explora^ 

 tory work has been under way throughout the past year. 



The Lake Sanford ore bodies are the largest of their kind in the 

 Adirondacks and undoubtedly rank among the largest deposits of 

 iron ore in the entire country. They were first made known to the 

 public through the descriptions of Professor Emmons in his reports 

 on the Survey of the Second Geological District. They have since 

 been investigated by Prof. J. F. Kemp,^ who has given a very 

 full account of their geology as well as of their mineralogical and 

 chemical characters. 



The diamond drill tests made during the past year have demon- 

 strated that the ore bodies, which have hitherto been known only 

 from outcrop, extend to considerable depths and that there are 

 enormous resources of ore available for easy extraction. On the 

 Sanford deposit the drills have shown as much as 3,60 feet of ore, 

 and they have nowhere passed into the foot wall. This ore body 

 was prospected by Professor Emmons who, as a result of his obser- 

 vations which have been recorded with much detail, estimated that 

 it contained over 6,000,000 tons of ore within a distance of 2 feet 

 below the adjoining surface. The bounds of the deposit as known 

 to him have been greatly extended by subsequent investigations. 



The ore from this locality is a coarse titaniferous magnetite. It 

 is nearly free from admixed minerals of the wall rock, except on 

 the borders where more or less feldspar and pyroxene are present. 

 The deposit is well situated for working, as it outcrops along the 

 sides and crest of a hill which rises about 300 feet above the shore 

 of Lake Sanford. Quarry methods can be used here to advantage. 



The recent exploration has disclosed the existence of an area 

 of ore-bearing ground north and west of Calamity brook, near the
