724 GEOLOGY AND TOPOGRAPHY OF THE LEAD REGION. 



Speiusley & Co. This is also on the land of Dr. Stanley, and is a short distance east 

 of the preceding. It is an east and west rang*, situated a little north of the Dry bone 

 Hollow range. The range is 130 feet wide, so far as has been worked, and may prove 

 to be 200 feet in width each way from the center. The ore makes in pitches, and the 

 sheet varies in size according to the number of feeders coming in from above. The lead 

 ore occurs much mixed with rock, which necessitates crushing and jigging the entire 

 product. 



The lot worked by these parties consists of about six acres, of which only about one- 

 sixth has been explored. The ore is blende and lead ore; some Smithsom'te is said to 

 be found in the north and northwest portions of the ground, while the blende is found 

 in the southern part. The amount of water here is small, and is all removed by bail- 

 ing, and hoisting in a barrel containing about 50 gallons. 



Three shafts have have been sunk, one of which is down to the Blue limestone, and 

 is 100 feet deep 

 The company have operated here for six years, with the following product: 



Blende. Lead ore. 



Year. tons. Ibs. 



1871 70 60,000 



1872 150 120,000 



1873 350 150,000 



1874 250 160,000 



1875 300 257,000 



1876 325 300,000 



Siddel & Co. They are situated on the same range, worked in the same opening as 

 Spensley & Co., and are located about 150 feet east of them. They are the most east- 

 erly of all the diggings in this vicinity. One shaft has been sunk, and the ore has been 

 found to make in the same manner as the preceding, except that this ground already 

 furnishes some Smithsonite from the north side. These parties have been working here 

 for the last five years, during which time the average annual product has been as fol- 

 lows: Lead ore, 70,000 Ibs.; Smithsonite, 85 tons; blende, 70 tons. 



Flynn, Lynch & Co. On Dr. Stanley's ground, and about 300 feet southeast of 

 Spensley & Co. Their ground is a lot 250 by 350 feet. One shaft has been sunk here 

 80 feet to the top of the opening, which is here 6 feet high and 100 feet wide. The 

 ground produces lead ore and blende, occurring in a flat sheet, mixed with the top layer 

 of the Blue limestone and some pipe clay. The company has been working about five 

 years, since which time, to October, 1874, they have produced 250,000 Ibs. of lead ore 

 and 700 tons of blende. 



Robinson's Diggings. Situated about 300 feet southeast of the preceding, on the 

 ground of Mr. Barnxd. These diggings are not being worked at present. They were 

 commenced in the winter of 1871-2, and produced 4,500 Ibs. of lead ore and about 9 

 tons of blende in the first two years. 



Williams & Edwards. Situated on the land of Mr. Lampe and about 500 feet 

 west of the diggings of Blackney & Co., previously described. They are part of the 

 Spensley and Lynch range. 



The works are in the Brown-rock, which here appears to divide into three subordinate 

 openings. A section of their working shaft is as follows, all in the Galena limestone :
