734 GEOLOGY AND TOPOGRAPHY OF THE LEAD REGION. 



have been mining here during the last ten years. The ore is found in three flat open- 

 ings. The first is from ten to twenty feet below the surface, and contains chiefly Smith - 

 sonite in sheets of three inches thickness. The second opening is ten feet deeper, con- 

 taining the same ore, mixed with galenite, in sheets of three inches. The third open- 

 ing is ten feet below the- second, and contains chiefly blende in sheets averaging four 

 inches. The description of these openings applies to all the other mines in the range. 



Other parties working on this range are Cox & Co., Jas. Hitching & Holinan, and 

 Harris and partner. 



The mining ground on this ridge is owned in small lots by several parties, among 

 whom are Messrs. Ross, Priestly, Tyck and Prideaux. [t was found impossible to ob- 

 tain any information of the amounts of ore produced on this ridge, but it is safe to esti- 

 mate ore to the amount of $600 per annum for each man, and this is probably much 

 beneath the actual amount. 



William Prideaux Mines. S. E. qr. of N. W. qr., Sec. 30, T. 5, R. 3 E. This is a 

 part of the Ashbank range, so called from the decomposed appearance of much of the 

 surface lead ore. It was discovered more than thirty years since, and worked er- 

 tensively for lead ore. The course of the range is nearly northwest, and its average 

 width about 25 feet. The principal product of the mine is Smithsonite, with some lead 

 ore. The workings are chiefly in the green-rock opening, where the ores are found in 

 flat and pitching sheets, from two to eighteen inches thick. The ground is dry and the 

 workings rather shallow, seldom being more than fifty feet below the surface. In one 

 place, where water was troublesome, it was removed by drilling a hole 54 feet deep, 

 draining it off through a lower opening. During the present year (1876). about 51,000 

 pounds of lead ore and some blende were obtained in the Brown-rock opening. Mr. 

 Prideaux commenced work in April, 1873, and now employs six men. He estimates 

 that from January 1, to October 1, 1876, the value of ores produced is $6,500, and 

 about the same amount from April, 1873, to January 1, 1876. 



A short distance southwest of the preceding, is a parallel range not worked at present, 

 but regarded as a valuable mining ground. 



J. Jackson & Co. These diggings are also on the Ashbank range, and a short dis- 

 tance east-of Wm. Prideaux. The ores produced are Smithsonite and galenite in nearly 

 equal amounts, found in flat sheets in the green rock, and its opening from 15 to 40 feet 

 below the surface. The range is about 40 rods long and 350 feet wide ; ten shafts have 

 been sunk upon it. Work was commenced here in 1868, since which time it has been 

 continuous, the mines proving very productive. No exact amounts could be ascertained, 

 but the owners estimate the value of ores produced since 1868 at $18,000; the present 

 year being the most remunerative. 



Mitchell & Pollard. N. W. qr, of S. W. qr. Sec. 30, T. 5, R. 3 E. This range is 

 situated about 60 rods southwesterly from the Prideaux mines. These parties have been 

 working about four years, producing Smithsonite and lead ore. The workings are shal- 

 low and dry, similar to the Ashbank range, but not so productive. 



Sinapee Diggings. These mines are situated on the N. E. qr. of S. E. qr. of Sec. 

 30. They were discovered in 1845, have been worked continuously since then, and now 

 furnish employment to several parties, among whom are: 



Samuel Prisk and Win. Paynter. These parties commenced work in the fall of 

 1875, and have produced during the last year about 50 tons of Smithsonite and some 

 lead ore. The diggings are quite diy and average about 15 feet in depth. The ore is 

 found in flat sheets the principal workings being in the glass -rock opening. Four men 

 are employed here. This mine furnishes fine cabinet specimens of galenite. The range 

 is about 500 feet long, from 100 to 150 feet wide, and has a general east and west 

 course. The ore sheet is from two to four inches thick. 



Prisk & Coad. This is a parallel range situated about 300 feet south of the preced-
