MINES — MINERAL POINT DISTRICT. 737 



clay opening, at a depth of from 1 to 60 feet below the surface. The range is from 60 

 to 70 feet -wide, and has been worked to a distance of 350 feet. 



Jeffrey & Bro. Situated about 100 yards south of the preceding, and probably on 

 the same range. The range is here 100 feet wide, and produces lead ore, and both kinds 

 of zinc ore, in about equal quantities, and considerable iron pyrites. The work has been 

 chiefly done in the winter season during the last two years. 



Short & Foster. Situated about 200 yards west of Jeffrey & Bro., on an old north 

 and south range, siKty feet in width. They have been working during the last two 

 years in the winter season, producing lead and zinc ores from the pipe-clay opening. 

 The diggings are about 40 feet deep. 



Mankey & Son. Situated about 150 yards S. E. of Jeffrey & Bro. They have been 

 working during the last twelve years on a north and south range. The product is lead 

 ore found in vertical crevices, and in flat sheets in the green-rock opening at a depth of 

 40 feet from the surface. 



All the diggings on this hid are dry; and most of them are remunerative, but the 

 amounts of ore produced could not be ascertained. 



The mining land is owned by Messrs. Henry, Coad, Prideaux and Woodman. 



About a quarter of a mile north of this ridge is the Mineral Point Hill, lying di- 

 rectly east of the city. The following parties are mining there: 



Vivian & Sleep. This party is working a nearly east and west range, the most 

 southerly of several parallel ranges which cross the hiU. The range is about 50 feet 

 wide, and produces zinc ores, chiefly Smithsonite, from the upper pipe-clay opening, 

 which is here about 25 feet below the surface. They have been working here during 

 the last thirteen years, operating during the entire year. 



Brown & Cluthers. They have been mining about a year on a parallel range 150 

 feet north of the one last mentioned. The range is about 50 feet wide; and produces 

 zinc ores, chiefly blende. The ore is found in flat and pitching sheets in the pipe-clay 

 opening. 



James Dunn & Son. This party has been working about three years on a rang;e 

 150 feet north of the preceding. Both kinds of zinc ores are produced from the upper 

 pipe-clay opening, which hes here about 40 feet deep. 



Trewilla & Strong. This party has worked about eight years in this vicinity, and 

 one and a half years on their present range, producing zinc ores. 



Goldsworthy & Hocks. Situated about one-fourth of a mile east of Yivian & Sleep. 

 They have been mining about a year, producing blende. 



The mining land in this hill is owned by Messrs. Hutchinson, Henry, Curry, Gundry 

 and Washburn. The ranges all bear a little north of west and south of east, and have 

 never been worked below the upper pipe-clay opening. 



The earliest mining in this vicinity was done on the Mineral Point HiU. Tlie ranges 

 were formerly very productive, and have been worked continuously for many years to 

 the present time. There are a few other parties mining within a few nules of Mineral 

 Point. They are as follows: 



Rogers & Mankey. Situated on the N. E. qr. of Sec. 8, T. 4, R. 3 E., on land 

 owned by Mr. Suthers, near Rock branch. Tliis is a new discovery made in October, 

 1876, bemg a flat sheet of Smithsonite in the Brown-rock opening. 



Jeffrey & May. Situated a short distance north of the precerling. This is also a 

 new discovery made about the same time as tlie preceding, being a flat sheet of zinc 

 ores in the glass-rock opening. The prospect is very good. 



Badcroft Diggings. Sec. 15, T. 4, R. 3 E. Work was begun here in 1872, and has 

 been continued at intervals since. Three men have been employed, chiefly in prospect- 

 ing, and a smaU amount of lead ore has been produced. The ore is found in flat and 

 pitching sheets in the pipe-clay opening, about 20 feet below the surface.
