Engineering Reports
The Following are Extracts From Other Mining Engineers Reports:
Mr. Alex Hill, an eminent English Mining Engineer, well-known as a high authority on mining, both in England and in Canada. Mr. Hill acted as consulting engineer for the English Company.
Extracts from report by Alex Hill, of London, England, dated June 12th 1907: —-
“Mine is looking well and promises better: the Mill is running well.”
“I estimate that our ore reserves are at least 45,000 tons, worth $6.00.”
“Estimated profit not less than £7,000 ($35,000) per annum.
“I estimate that our ore reserves are at least 45,000 tons, worth $6.00.”
“No. 1 shaft has now reached the depth of 401 feet 6 in., and levels have been drive at the depths of 300 feet and 400 feet. At the 300-foot level the east drift has a length of 122 feet, and the west drift 16 feet 6 in. At the 400-foot level the east drift is 54 feet 6 in. long and the west drift 69 feet. A slope has been begun on the 300-foot level, east drift, which presents a very good appearance. The leader of vein of ore was quite narrow when first encountered, but rapidly opened out to nearly 20 feet in width. This ore shoot appears to be on what is known as the “Spur Lode,” and may probably continue in an upward direction as well as down towards the east.”
“At the 400-foot level to the eastwards the indications are very promising. The ore on the main lode which we expected to cut at this depth has been encountered, and though the vein is narrow it is of excellent quality and appears to be widening out very regularly.”
“To the west at this level the lode continues in a very satisfactory manner. The ore streak is of fair width and of good quality. When the drift is continues somewhat further a slope could be opened here. I had not expected to encounter good pay ore in this direction quite so soon, and have been very agreeably disappointed.”
“It is satisfactory to note the the lode in the lowest level (of No. 3 shaft), namely, 285-foot level, has improved in quality being distinctly better than in the 185-foot level.”
“This ore, after selection, ought to yield six dwts ($6.00) per ton. The ore that has been extracted and treated since the new mill started work in March last, amounts to 3,644 tons, the production of gold being 1.198.25 ounces, which at $18 per ounce equals $5.92 per ton. To this has to be added the gold in concentrates capable of extraction by the cyanide process, which amounts to about 40 ounces, so that the extraction may be taken at rather over $6 per ton.”
