workings comprising this group lie chiefly south of the Carmel, or 
Cold Spring, road, about 7 miles east of Cold Spring. They con- 
sist of cuts and pits opened along the outcrop, about a mile in length. 
The ore pinches out at the southern end of the workings, low 
swampy ground intervening between the Canada pits and the con- 
tinuation of the ore belt to the southwest. 
After an apparently barren interval of about a mile the ore con- 
tinues in the same direction; it was quite extensively mined at this 
point, the workings being known as the Sunk or Stewert mines. 
The ore was worked nearly 1ooo feet along the strike, and to a 
depth of 300 feet. 
The further exploration of the belt to the southwest resulted in 
the opening of the Sackett, Pratt and Denny mines, situated along 
the belt in the order named. The Pratt and Sackett mines are offset 
from the Sunk mine by a transverse fault of small throw. The 
openings are just north of the road leading from Dennytown to 
Canopus creek; they consist chiefly of a series of open cuts extend- 
ing for 300 feet or more; the Sackett workings are just north of 
the road, the Pratt pits lying south of it. 
About one-fourth of a mile southwest of the Pratt workings, and 
on the crest of the hill, lie the Denny pits; the workings seem to 
indicate a greater irregularity in the mode of occurrence of the mag- 
netite than is the case in the other mines in this belt. (See fig. 11.) 
The Canopus mine. About 3 miles to the southwest of the Denny 
workings but in the same line of strike, an occurrence of magnetite 
at Travis Corners forms what may be considered the extreme 
southern end of the Phillips belt. The property was prospected 
many years ago, being known at one time as the Nelson mine, but 
called, by the company last operating it, the Canopus mine. 
No further extension of the Phillips belt to the southwest has been 
discovered.

There are two old mines located along this “ belt’? of ore. They 
might possibly be more correctly placed in the group of isolated 
occurrences, were it not for the fact that they lie in the same gen- 
eral line of strike and have certain features in common. Provided 
these mines be considered as lying at the extremities of the belt, and 
to delimit it, then the Sprout Brook belt represents a direction some 
3 miles in length, at each end of which is located a mine from which 
more or less magnetite has been taken in the past.
