MINES -LINDEN DISTRICT. 799 



The three mmes 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. VV. qr. Sec. 8, on the west 

 side of the Heathoock branch. Wearing & Goldsworthy, owners. This range was dis- 

 covered about forty yeai-s 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, di-ained by a level 40 rods long. In former years it was worked for Smithsonite at 

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

 5,000 pounds; blende, 100 tons. 



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

 southwest of Treglown & Wicks. They have been working dm-ing the last seven 

 years on the Mon-ison 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 stUl 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 viUage of Linden, near 

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

 the glass rock in a flat sheet from 10 to 15d 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 aljout 150 feet 

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

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

 September, 1876, they have i^roduoed 35,000 Rs. of lead ore, and 40 tons of blende. 



Tliomas 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 dry bone, cropping out at the foot of a hiU; on working 

 into the hiU the amount of Smithsonite was found to dimirash, and the blende to in- 

 crease; which seems to bean 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 fom- east 

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

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

 They axe 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 lbs., 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 lbs., and in 1876, 40,000 lbs. The mine has not been worked much 

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