738 GEOLOGY AND TOPOGRAPHY OF THE LEAD REGION. 



Shepard & Co. Situated on the N. E. qr. of the N. E. qr. of Sec. 22, T. 4, R. 2 E. 

 Work was commenced here in August, 1876, on the old Maloney range. This range 

 has a general east and west course, and yields lead ore and blende from the pipe-clay 

 opening, which is here about 25 feet deep. The ore occurs in a flat sheet from 4 to 5 

 inches thick, the blende forming the top and bottom of the sheet, and the lead ore the 

 central part. The product has been, to December, 1876, lead ore, 1,500 pounds; 

 blende, 3 tons. The ground is dry, and the prospect is considered good. 



Clebenstein Diggings. They are situated on the same ridge and a short distance 

 east of the preceding. They are now operated by August Cain, who has been mining 

 about a year. They were operated from 1865 to 1875, by Mr. Clebenstein, and pro- 

 duced large amounts of lead and zinc ores. The ore was found in flat sheets, in the 

 pip^-clay and glass-rock openings. 



H. Josephs Diggings. Situated on the W. hf . of the S. W. qr. of Sec. 5, T. 4, R. 3 

 E. Mining was commenced here in 1871, and continued until the fall of 1874, when it 

 was discontinued on account of water. The ore found here was exclusively blende, 

 which occurred in a flat sheet, in the green-rock opening. The width of the sheet was 

 about-80 feet, its greatest thickness three feet, and it was worked for a distance of 800 

 feet. The greatest depth below the surface is 70 feet. During the years 187:3-4 this 

 ground produced about 1,000 tons of blende. 



Diamond Grove Diggings. 



These diggings are situated on Sees. 25 and 26, T. 5, R. 2 E. They produce chiefly 

 zinc ores, found in flat sheets in the pipe-clay and glass-rock openings. The following 

 parties are now mining here : 



Cain & Read. Situated on the N. W. qr. of Sec. 25. This party has been working 

 on the Rodersdorf range during the winters of 1873-4 and 1874-5. The ore, which is 

 Smithsonite, is found in the glass-rock opening, in a range from 16 to 20 feet wide, and 

 200 feet Jong. The production during the first season was 17% tons, in the second sea- 

 son, 20 tons. 



Robert Conley & Sons. Situated on the S. W. qr. of Sec. 25. Mining has been 

 carried on here by the above party during the last ten years on an east and west range. 

 Both kinds of zinc ore and lead ore are found here in the pipe-clay and glass-rock open- 

 ings, but chiefly in the latter. The range is from forty to sixty feet wide, and has been 

 worked a distance of 150 yards. During the last year and a half the product of lead 

 ore has been 60/)00 pounds, and sixty tons of zinc ore during the last two years. 



Biddick Diggings. A valuable deposit of lead ore has lately been discovered on 

 the S. W. qr. of Sec. 24, T. 5, R. 2 E., on which four men are now employed running a 

 level. Four flat sheets, from one to four inches thick, are found here situated above 

 one another, in the upper pipe-clay opening. It has not yet been sufficiently worked to 

 determine its actual extent. 



Martin Bros. & Cramer. Situated on the S. W. qr. of Sec. 25. This and the pre- 

 ceding are on land owned by Mr. James Spensley. They have been mining here on an 

 east and west range, which was discovered two years since. The ore is Smithsonite; 

 and is found in the glass-rock opening, which is here from ten to thirty feet deep. 



Spensley & Brown. Situated on the N. E. qr. of Sec. 26, T. 5, R. 2 E. Six men 

 have been employed here since July 1876 driving an adit in the glass-rock opening. The 

 adit is 200 feet long, and drains an east and west range. The product has been, lead 

 ore, 36,000 pounds, blende, six tons. 



Opir & Lancaster. Situated on the N. W. qr. of Sec. 26. This party is working 

 the same range, 450 yards west of the preceding. It is here known as the Lancaster 

 range, and has been worked by the present party about a year. From three to five men 

 are employed, and the product has been 150 tons of blende. It is worked by an adit.
