THE ASBESTOS HILL - IMORDENHAM STORY - Introduction

Abstract Asbestos Corporation Limited, incorporated in 1925, operates four asbestos mines and three asbestos mills in the Thetford Mines region of Quebec's Eastern Townships. A unique asbestos orebody, located in the Ungava Peninsula of Nouveau Quebec, was purchased by Asbestos Corporation Limited in 1964 and commenced production in 1972.
As there were no existing facilities in the isolated, arctic region of Asbestos Hill, it was necessary for Asbestos Corporation Limited to construct at Deception Bay a deep-sea wharf, a large ungraded fibre shed, a power plant and camp facilities. Forty-two miles of road were needed and were constructed from Deception Bay to Asbestos Hill. At Asbestos Hill, a complete crushing-drying-milling complex, a power plant, personnel accommodations and open-pit facilities were provided. Unloading facilities and a fibre finishing mill were constructed at Nordenham, West Germany.
The "Asbestos Hill - Nordenham Story" is divided into individual papers covering all aspects of the engineering, construction and operation of this unique enterprise. Particular emphasis has been placed on those unusual aspects caused by the isolated location, arctic conditions, short shipping season and the deep permafrost.

Summary: The ungraded-fibre mill is located at the mine site and has a rated capacity of 6,600 tons of ore input and 1,200 tons of ungraded fibre product per day. Power for operation is obtained from a diesel generating plant located on the site, which has a capacity of 5,300 kW.
The preliminary milling process consists of primary and secondary crushing, drying and temporary storage of plus-lVz-in. material.

Summary: Taxation tends to be a depressing subject. Taxes are unfair, taxes are too high and, above all, taxes are too complicated.
In a recent address to the Canadian Tax Foundation, the author discussed in a rather more lighthearted way the possible causes of the complexity of the present Canadian taxation system. In order to provide an element of relief in this series of articles on taxation matters, extracts from these remarks are quoted below

Summary: The Nordenham finishing mill is situated in the town of Nordenham, Federal Republic of Germany, on the banks of the Weser River opposite the town of Bremerhaven, with access by water to the North Sea.
The unfinished fibre, shipped from Deception Bay during the sub-Arctic summer shipping season, is unloaded from bulk ocean carriers, stored and then processed throughout the year until the following shipping season.
This paper describes the unloading and storage facilities, the finishing mill...

Summary: In 1957, an asbestos orebody was discovered in the northern sector of the Ungava Peninsula of the Province of Quebec, an area now identified as Asbestos Hill. The deposit is situated on a plateau 1700 feet above sea level and 42 miles inland from Hudson Strait. It is a bleak, isolated location of typical arctic environment.
Fifteen years were to pass before the first shipment of ungraded fibre was made in 1972. These years were occupied with field surveys and investigations, diamond drilling,...

Summary: The yearly production from the Asbestos Hill pit is 1,550,-000 tons of asbestos ore, with a yield varying between 18 and 20%. The orebody was exposed at the top of a hill, and initial production started without having to remove any overburden. The projected ratio of barren rock to ore, based on the present orebody, was 2 to 1. However, as it was necessary to push back the upper benches, this ratio has changed to 3 to 1.
The final pit will be 2,300 feet long by 1,000 feet at the longest and...

Summary: This paper defines the responsibilities and functions of the Maintenance Department, and its organization, physical and human assets, highlighting the unique operating problems.
Due to the self-sufficient aspect of the Asbestos Hill -Deception Bay project, the Maintenance Department covers fields that are numerous and very dissimilar: production, mobile, processing, service, power generation, fire protection, heating, water and sewage disposal equipment. Added to this, buildings, plant and...

Summary: The asbestos orebody is contained within ultrabasic rocks of Precambrian age, being located in the continuous permafrost zone of the Quebec Ungava Peninsula, some 300 miles north of the tree line at approximate latitude 61°49' and longitude 73°58'.
The asbestos deposit is at the western tip of a folded ultrabasic sill complex which trends northeast and covers an elliptical area 4-5 miles wide by 15 miles long. Locally, the asbestos occurs in a completely serpentinized dunite rock. The...
