710 GEOLOGY AND TOPOGRAPHY OF THE LEAD REGION. 



90 gallons per minute. It is estimated that the ground has produced a million pounds 

 of ore, and its present annual product is about 300,000 pounds. 



NEW DIGGINGS DISTRICT. 



Considerable lead ore is now being raised in the vicinity of New Diggings, being 

 mostly on the ridge immediately south of the village. The following section taken from 

 the mines south of the village will give a correct idea of the relative position of the sev- 

 eral beds and openings :

Champion Diggings. N. E. qr. Sec. 26, T. 1, R. 1 E., on the New Diggings ridge 

 There are several ranges here having a general east and west course, one of which, 

 known as Champion's old lode, has probably yielded more than any single range in the 

 Lead region. This and the other ranges owned by Mr. Champion are drained by a 

 level half a mile long. This was completed in the year 1865, at an expense of about 

 seventy thousand dollars. It then drained the ground, and in four years, with the labor 

 of eight men, 5,000,000 pounds of ore were taken out, which sold for about $500,000. 

 This ore was contained in an immense opening, in some places forty feet wide by twenty- 

 five feet high. This principal opening is now worked out, but the range still continues 

 productive, and has been worked uninterruptedly for the last ten years. Average pro- 

 duct per year, 85,000 pounds. 



Work is now being carried on south of the old ranges, at the western end, in the 

 Myers lot; a shaft has been sunk seventy- three feet to the first opening, which is here 

 about 10 feet high, and from 20 to 30 feet wide. There are here three parallel crevices, 

 one of which is about 8 feet wide. Seventeen men are now employed in the Champion 

 Diggings. Mining is carried on continuously, and the annual product is about 200,000 

 pounds. 



Craig Diggings are situated on the New Diggings ridge on the N. E. qr. of Sec. 

 26 and N. W. qr. Sec. 25, T. 1. R. 1 E. There are here three principal east and west 

 ranges, a few feet apart. The one which is now worked is known as the Simpson Pump 

 range. These ranges were discovered in 1834. In the spring of 1874, a shaft was sunk 

 on one of them, and they are now worked in the second opening. They produce only 

 lead ore, found in a flat opening which is 100 feet wide, and has been worked to a length
