Western Portion Of The Torbrook Tron Ore Deposits.
By
Howells Fréchette, M.Sc.
The Nietaux-Torbrook iron ore deposits are situated on the southeastern side of the Annapolis valley, in Annapolis county, Nova Seotia, about 5 miles south- east of the Dominion Atlantie railway. The ore-bearing district extends south- westward from the line between [Kings and Annapolis counties, for a distance of about 5 miles, and is slightly over a mile in width. The Nietaux river, flowing to the north, divides the area into two parts. That to the west of Nietaux river is known as the Nictaux district; while that to the east is known as the Torbrook district.
The history awd general description of the iron ore deposits are dealt with by Dr. J. E. Woodman in his report on the Tron Ore Deposits o Nova Scotia,’ part IT, chapter I. The geology and stratigraphy are described by Prof. L. W. Bailey,’ and the late Mr. Hugh Fletcher?
The rocks of the district are dark grey and black slates and quartzites, with a few intrusions of diorite and granite.
During the summer of 1910, the southwestern portion of the Torbrook district was examined. Magnetometric and topographic surveys were made, covering an area 2 miles northwest and southeast by 13 miles northeast and southwest, Iving immediately to the east of Nictaux river. The accompanying map (No. 141), which includes most of this area, has heen prepared from the surveys made, and from the map accompanying Mr. Fletcher’s report.
The northwestern portion of the area represented by the map has an altitude varying from 300 feet to 440 feet above sea-level, and the southeastern portion from 400 to 580 feet. Traversing the area is a valley, through which the Tos- brook or Black river flows, grading from 360 feet to 220 feet above the sea.
There are two parallel zones of ore, distant about one mile from one another: one of which is on the northwest side of the area under examination—which for convenience will be referred to as the ‘north side;’ while the other is across the valley of Black river, near the southeast side of the area—whieh will be referred to as the ‘south side,’ or, as it is locally known, ‘South mountain,’
Both on South mountain and on the north side, numerous pits have been dug exposing the ore which is in beds conformable with the slates and quartzites
’ Publication No, 20, Mines Branch, Department of Mines. a ? Geological Survey Annual Report, Vol. IX, p. 91M. : a " “ Vol. XVI, p. 302 A.
in which they oceur. The strike of the beds is N. 40° E.' On the north side, there are two main beds dipping about 80° to the southeast. The northernmost of these—the ‘ Leckie bed ’—is of hard hematite which is slightly magnetic. About 100 feet southeast of this is a bed of fossilifero: s magnetite known as the ‘Shell’ bed. On South mountain only one bed is seen. The dip of this is from 73° to 87° to the northwest. The ore in most parts of this bed is a low grade magnetite, highly siliceous, and of a waxy lustre. Very few fossils are to be seen in it.
The slates, quartzites, and iron ore are all steeply inclined. It has been pointed out by previous observers that the strata lie in a syncline and that the ore bed on South mountain is, probably, identical with one of those on the north side.
Mr. Fletcher, in his report for 1905,’ states that certain investigations at the old mines in the castern portion of the Torbrook district seem to prove that the rocks lie in several synclines between the ore exposures on South mountain and those on the north side.
The dips of the strata at various points in the area shown on the accompany- ing map tend to indicate that multiple folding has also taken place here. These dips, which are very steep, may be misleading, as they are doubtless effected in some cases by nearby intrusives. At present, the evidence to be seen in the dip and sequence of the strata is insufficient to make it possible to state positively the nature of the structure.
Tf there is multiple folding and the folds are large, the ore beds might be expected to outcrop or approach within workable distance of the surface within the Black River basin.
Magnetometric Surveys.
Magnetometric surveys were made on both South mountain and on the north side, with lines of observation connecting.
South Mountain.
A base line 6,400 feet long, approximately following the line of pits in the South Mountain ore, was laid off, and cross lines were turned at intervals of 300 feet, and in some places intermediate lines were run. The length of the cross lines averaged 1,700 feet to the north of the base line, and 1,250 feet to the south. Magnetometric observations for vertical and horizontal intensity were made at intervals of 50 feet along these lines, and at such other points as were deemed necessary. It had been hoped to locate the presence of additional beds of ore, and discover lines along which these beds approach the surface, due to multiple fold- ing. Unfortunately, no such results were obtained, but the known bed was traced from pit No. 1, on Obadiah Brown’s farm, westward to Black river.
The magnetism of this bed is weak throughout most of its length. For a distance of 1,800 feet, with the exception of about 300 feet, it could not be traced magnetically, and as there were no pits within this stretch it could not be ascer-

!
tained, without much trenching, whether the ore is continuous but non-magnetie, or absent.
The presence of two faults was observed. The first of these, marked No. 1 on the plan, offsets the bed about 100 feet to the northwest. The second fault, marked No. 2, is 780 feet southwest of the first, and offsets the bed about 55 feet to the southeast. From this point the bed was traced withont interruption to the point where it crosses Black river, about 1,100 feet down stream from the mouth of a small creek which flows into Black river.
The maps issued with the reports of Fletcher and Woodman show an offset of the bed at Black river. The line of outerop from the southwest is shown as meeting the river at the point 1,100 feet down stream from the mouth of the creek; but the line from the northeast is shown as meeting Black river at the mouth of the creek. This is certainly ineorreet. No outcrop was found to the southeast of pit No. 13, nor did the magnetometer indicate magnetic distur- bances.
Norte Side
A base line 8,850 feet long was run, parallel ta the south base line, near the northside beds. Cross lines were run at intervals of from 50 feet to 200 feet, averaging in length 650 feet to the north of the base line and 450 feet to the south. Magnetometric readings were taken at intervals of 50 feet along these lines, and in the neighbourhood of the ore additional readings were taken every 123 feet. The magnetometer indicated the presence of four magnetic beds more cr less parallel to each other. The southeasternmost is the ‘ Shell’ bed already mentioned, and indicated on the map as No. 1. This bed is strongly magnetic throughout its length in the area surveyed. About 65 feet to the northwest of the ‘Shell’ bed is No, 2 bed, which is only slightly magnetic in places. This is probably very narrow, and of no commercial value. No. 3 bed, lying about 100 feet northwest of No. 1, is the Leckie bed. It is somewhat more magnetic than No. 2, but cannot be traced continuously by means of the magnetometer. Vary- ing in distance from about 350 feet to 750 feet to the northwest of No. 1 bed, is No. 4. The magnetism is very low, and the bed could only be traced for short distances. A trench which euts this reveals the fact that it is only a bed of rather highly ferruginous slate.
The magnetometric survey indicated the presence of a number of faults, five of which are wel! defined and are shown on the plan. Following the beds fromm northeast to southwest, the first fault, No. 3, offsets the beds about 50 feet to the northwest. Eighteen hundred fect from No. 3 is No. 4 fault, the direction of which is almost due west. The offset is over 700 feet. No. 5 fault offsets the beds 50 feet to the northwest, and No. 6 offsets about 75 feet to the southeast. No 7 fault is to the west of the Bloomington road. The offset here is atout 70 fect to the southeast.
Contours of elevation above sea-level, for 10 ft. intervals, are shown in byown on the map.
Nature of Ore. SOUTH MOUNTAIN The following analyses, taken largely from Dr. Woodman’s report, will serve to show the character of the ore on South mountain.

It will be noted that in most places the ore is very low in iron, and highly siliceous. The analyses which show high iron content are from picked samples or samples from narrow bands in the ore bed.
The bed is made up of alternate narrow bands of ore and slate. The widest of these ore bands seldom attains a thickness of more than 5 feet. The aggregate thickness of ore average about 8’-4” in a total thickness of 15’-10”. These figures are deduced from sections measured by Mr. Fletcher.
Owing to the low grade character of the ore, and the difficulties of transporta tion, the South Mountain bed can hardly be looked upon as showing much com- mercial possibility.
Nortil Side,
The ‘Shell’ bed, as before stated, is magnetite, containing numerous fossils of Lower Oriskany or Eo-Devonian age. On page 14, part I. of Dr. Weoduian’s report, is the following average of analyses of the ore from various part of this
bed. Jt is compiled from analyses from various sources :—

No. 1 Mine: Canada Iron Corporation.
There are a number of openings in this bed from which ore has been shipped, but at present no ore is being mined. The Wheelock, or No. 1 uone, of the Canada Iron Corporation, has been the chief producer. It was operated from 1905 to i908, shipping ore to Londonderry, N.S. The thickness of the bed varies greatly in this mine, being as much as 18 feet in some places. The following is given by Dr. Woodman as the average analysis of the ore shipped :—

No. 2 Mine: Canada Iron Corporation.
At present, the only mine being operated on this bed is No. 2 of the Canada Tron Corporation. It is situated about 2,000 feet southwest of No. 1, or Wheelock mine. The shaft is down 500 feet, with five levels on both sides. On the west side, the levels all measure about 325 feet in length; while on the east side they vary from 150 feet to 650 feet. Cross-cuts have been driven from the second and fifth levels to the ‘Shell bed, which at this point is 100 feet to the southeast. In the levels the ore is found to vary in thickness from 3’-9% to 6’-6”, with an average of about 5 feet.
This mine has the following mechanical equipment :—
Five return tubular boilers, 500 TTP.
One double drum hoist.
Two single drum hoists.
Twenty-four Murphy drills.
Eleven Rand drills.
One Leonard-Ball tandem compound engine, 13” and 22” x 12” stroke. This engine runs at 250 R.P.M., which gives about 125 H.P.

One Laidlaw-Dunn-Gordon duplex, cross compound air compressor, capacity 1,600 enbie feet free air, delivering at 90 pounds per square inch (which can be varied to 130 pounds if necessary).
One 35 K.W. Allis-Chalmers-Bullock D.C. generator, direct connected,
Working two nine-hour shifts, this mine has an output of 260 tons per day. There are about 80 men employed underground and 50 on the surface.
All the ore eaised is crushed to 3”, and passed over Zimmer shaking tables, where it is hand picked. By finer crushing and fur.ber concentration, the per- centage of iron might be increased materially, as the ore carries considerable attached rock,
During the past year, 11,000 tons of ore was shipped; which ran about 48 per cent in metallic iron, and 1-5 per cent in phosphorus,
The total quantity of ore raised from this mine was about 55,000 tons at the end of 1910,
Transportation.
A branch line 34 miles long connects the Torbrook mines with the Halifax and Southwestern railway at Nictaux.
At present all the ore is shipped over the Halifax and Southwestern railway to Port Wade: a distance of 55 miles, and thence by vessel to its destination. At Port Wade, a storage bin and loader were installed during the early part of 1910. From the storage bin—which has a capacity of 7,000 tons—the ore is transferred by a bucket conveyer to a hoppe at the outer end of the wharf, which delivers into the loading chutes.
Drill Holes.’
Three drill holes are shown on the accompanying map. One is on South mountain, and two are on the north side.
No. I is on the farm of Sam. McConnell, about 3,050 feet northeast of Black river. It was sunk in 1901 by the calyx drill of the Department of Mines of Nova Scotia, to a depth of 195 feet.
I Information relative io drill holes is taken from Dr. Woodman’s Report on the Iron Ores of Nova Scotia.
‘The log below is from the original by Mr. James Phinney, drillman. A slightly different version is in Nova Scotia Mines Department Report for 1901,

The strata dipped from 838° to 87° to the northwest, and the hole was vertical, Using 35° as the average dip in reducing the above figures to the thickness of the beds, we find the first bed of ore to be 3-1 feet thick, and tie second bed of ore 8.4 feet thick, with 3-2 feet of black slate intervening.
No. If drill hole is situated on the farm of Levert Parker (formerly the Josephine Wheelock farm), to the north of the Nictaux-Torbrook road, and 17 feet south of the Shell bed. This hole, which is vertical, was sunk in 1905 by the Nova Scotia Steel and Coal Company. ‘Details from the original log are not available.’

The dip here is not given. Taken at the ore bed in a surface trench, it is 85° S.E. Much of the core was found. In most parts the stratification is parallel with the core, or vertical. The planes are extremely distinct, with much pyrite occurring in them. The bottom of the hole was still in ore.’?
On the same property a diamond drill hole 115 feet long and inclined at 45° cut the shell bed 76 feet below the surface. The width of the bed here was slightly over 5 feet. his drill hole is not shown on the map.

Magnetic Concentration Tests.
Magnetie concentration tests by the Grindal method of separation have been carried on by Mr. G. C. Mackenzie in the testing laboratories of the Department of Mines at Ottawa, upon samples of Torbrook ore, both from the Hematite and Shell ore veins, results of which will be published in a separate report.
