The two main shafts are down 800 feet and another is 400 
feet deep, with the levels averaging over 700 feet long-. 
This work shows a vein averag-ing 14 feet wide and 
gives a million and a half tons of ore blocked out ready 
to stope, and which will yield $2.50 per ton by amalgamation. 
They have accordingly planned a mill large enough to treat 
1,000 tons of ore per day, making the estimated total cost of 
mining, milling and transporting the ore only $1.48 per ton. 
They are now waiting for the completion of their water- 
power plant before building the mill and since they have suf- 
ficient ore blocked out, the mine has been idle and full of 
water since the spring of 1905. The intention is to keep a 
reserve of 500,000 tons of ore in advance of the s toping. 
The Bonnie Doone, or Old Smart Mine, has also been prop- 
erly developed by Mr. J. C. Bates, a former owner of the 
Howie Mine. The old 80 foot shaft has been deepened to 200 
feet, with levels 125 feet long at 60 feet, 100 feet at 120 feet, 
160 feet at 186 feet. The ore obtained from these workings 
is now piled in a large dump estimated to contain 3,000 tons. 
And before the mill was planned, this was carefully sampled 
by a competent mining engineer, who dug deep trenches 
across it and found it to average $15.00 per ton. Of course a 
great deal of the same quality of ore has been blocked out in 
the mine. There are about 500 tons in another dump of 
material which came from work in the walls and is chiefly 
slate but contains a few of the veinlets and masses of milky 
quartz, and is said to assay about $1.50 per ton. It has been 
kept out of the good ore at only a nominal expense. The 
mill has not been built on account of the continued sickness 
of the owner, so there is no machinery at the mine except the 
sufficiently large prospecting hoist. 
As an example of a mill too large for the development may 
be mentioned the Reimer Mine, near Salisbury. Here a 20 
stamp mill with chlorination failed simply because no ore 
at all had been blocked out and it could not be mined rapidly 
enough to keep the mill going. An examination of the mine
