MINES LINDEN DISTRICT. 729 



The three mines on the Robart's range are estimated to produce annually 200,000 

 pounds of lead ore, and 100 tons of blende. 



Treglown & Sons and Capt. Wicks. S. W. qr. of N. W. qr. Sec. 8, on the west 

 side of the Heathcock branch. Wearing & Golclsworthy, owners. This range was dis- 

 covered about forty years ago, and has been worked continuously ever since. The present 

 company have been working it during the last two years in the glass-rock opening. 

 The ore is found about fifteen feet below the surface; the width of the range is 45 

 feet, drained by a level 40 rods long. In former years it was worked for Smithsonite at 

 higher levels, and was quite productive. Its present annual production is, lead ore, 

 5,000 pounds; blende, 100 tons. 



Adams & Son and JBowden. These parties are situated about a quarter of a mile 

 southwest of Treglown & Wicks. They have been working during the last seven 

 years on the Morrison range, producing annually about 50 tons of Smithsonite, and 

 7,000 pounds of lead ore. Water was removed from these diggings by drilling a hole 

 down to the glass-rock opening. 



David Morrison Diggings. W. hf . of S. W. qr. Sec. 8. The range is about 700 

 yards long, 40 feet wide, and has a general north and south course. The range was 

 discovered in 1846, and worked at various times for lead ore to 1874. Mr. Morrison 

 then opened the main sheet of blende, since which time the production has been as fol- 

 lows: in 1874, 90 tons; in 1875, 106 tons. During the present year the mine has not 

 been worked, although it is still good. The range is drained by a level 350 feet long. 

 The ore is found in flat sheets from 7 to 10 inches thick, on the top of the glass rock. 



Richards & Faul Bros. These diggings are situated in the village of Linden, near 

 the S. E. corner of section 8, on land owned by Wm. George. The ore is found under 

 the glass rock in a flat sheet from 10 to 1% inches thick, from 15 to 25 feet in width, and 

 from 13 to 30 feet below the surface. The water is removed by a drain about 150 feet 

 long. This mine was discovered in May, 1875. From that time to May, 1876, they 

 produced 80,000 Its. of lead ore, and 150 tons of blende. During July, August and 

 September, 1876, they have produced 35,000 flbs. of lead ore, and 40 tons of blende. 



Thomas Tamblin. Zinc ores were discovered on the N. W. qr. of the N. W. qr of 

 Sec. 10, T. 5, R. 2 E., on the 20th of December, 1875, on the land of Mrs. Thos. Shore. 

 The general course of the range is nearly east and west, and is now worked at an average 

 depth of 10 feet below the .surface, and has been proved to a distance of 40 feet. The 

 ore was found as a flat sheet of drybone, cropping out at the foot of a hill; on working 

 into the hill the amount of Smithsonite was found to diminish, and the blende to in- 

 crease; which seems to be an indication that the Smithsonite is a secondary product, 

 derived from the blende. It is estimated that two miners can produce here 100 tons of 

 zinc ore per annum. 



R. S. & W. J. Jacobs. S. E. qr. of S. W. qr., and S. W. qr of S. E. qr. section 

 7, T. 5, R. 2 E. This mine was discovered in March, 1875. There are here four east 

 and west sheets, from four to six feet wide and from four to six inches thick in the upper 

 pipe-clay opening, separated from each other by six or eight feet of unproductive rock. 

 They are worked about 20 feet below the surface. There is but a small amount of 

 water, which is bailed out. Some very large isolated masses of lead ore have, been 

 found here, one of which, weighing 1,527 H>s., was sent to the Centennial Exhibition. 

 Small quantities of zinc ores are also found. The mine produced during the year 1875, 

 of lead ore, 70,000 ft>s., and in 1876, 40,000 flbs. The mine has not been worked much 

 during this summer, as the owners are engaged in farming.
