Mining costs have shown satisfactory reductions. As the working areas have been
enlarged, a more efficient use of equipment has been possible. Heavier types of drills, trucks
and loading equipment can now be used, and should result in a further reduction of costs

and increased mining capacity.

Development
The adit was driven a further 293.9 feet. The first 145 feet was in good grade ore,
making a total of 668 feet. The remaining 148.9 feet was in serpentine of a marginal grade.

The dip of the orebody appears to be about 33°, with the true width 400 feet, excluding

the marginal serpentine on the hanging wall side.

A drift was driven along the hanging wall of the orebody. It broke out to the
North in the Cirque Valley in good ore. At the close of the mining season the South drift
had just come into waste, due we believe, to a change in the strike of the hanging wall. The
total length of ore drifted to date is 750 feet. With this information, an open pit programme
has been prepared, its first stage being the mining of 9,000,000 tons of ore now considered
to be indicated above an arbitrary horizon, 120 feet below the adit level. Further develop-
ment will be required to define the limits of the orebody on strike and at greater depth

before the next stage of the programme can be determined.

Mill

The mill treated 258,056 tons of ore for an average of 706 tons per calendar day,
with a fibre recovery of $26.80 per ton. Two new grades of fibre were successfully intro-
duced to the market, which largely accounted for the increased production. These grades
are “AAA”, a high-grade spinning fibre, and “AC”, a high-grade asbestos cement fibre.
Encouraging results have been obtained from research work on two other grades, and this

investigation will be continued.

Fibre control eifected by the mill laboratory has resulted in further improvement in

uniformity of grading and quality, which has been favourably received by the market.

Improvements in the drying circuit reported last year have resulted in increased

efficiency and lower costs.

At the close of the mining season on October 28, 1956, there were 106,851 tons in
the dry rock storage and 97,406 tons in the stockpile, sufficient to supply the mill until

cOmmencement of mining operations in June, 1957.
