REPORT

J. F. BOYNTON, GEOLOGIST,

North Siioue of Lake Soterior,
August 11, 1846.
Jams Bell Forsyth,
Sir,
I was emplnvofl in .Time Inst, to accompany
ail Kxpl<)rin,!v Kxpedilion on tho, Novth Sliore
of Lake SniH;rior, inuler tlie direetioii of Col.
C. IL Gratiot, to select Mineral Lands for the
location of a Permit belongin,^ to you.

Accordingly, on the Gth of -Tidy, in company
with W. K. "Logan, I'^sil. I'rovineial Geolo-
gist, we left Copper Harbor on the Schooner
Occ'a?}, bound for the Canada shore, and we
proceeded up the Lake to examine the Islands
and Coast, being between Spar Island and
Pigeon Iviver.

Our attention was particularly called by
Mr. E. 11. Thomson, to some large \ ems about
sixmiles west of Spar Island, where, after a
careful examination, we decided on locatnig
your Periuit.

The Location is situated about seven miles
east of the Boundary Line betwe .i the Uni-
ted States and Canada, on the mam Sliorc,
including a large peninsula of higli lulls ex-
tending into the Lake about two uules, belund
which w a most excellent Harbor, where ves-
sels may lie safely secured from storms commg
from any direction.

rJVEBS.

There are two Rivers emptying into the
Lake from this Location. One of ihem is four
rods wide with six feet of wuter over the bar
at its mouth.

We passed up this Piiver one mile and a half,
and found the water irom three to six feet

deep. At this distance tip the River, there is
a Full that Avould afford an excellent water
lower I'or propelling any Machinery that might
required for Mining operations.

SOIL.

At the mouths of these Rivers, there is a
large delta of fine rich l;ind tliat woul(l \e
easily cultivated, and affoid an abundant crop
of all the products of any country of its lati-
tude.

WOOD AND TIMBER.

The high land on the Location is covered
with a small growth of Sin'uce, Pine, Poplar,
and Birch — but on the low lands, and on the
sides of <he Rivers, there is a large quantity
of fine Timber that will be found highly valua-
ble for building, curbing, and other Mining
purposes.

ROCKS.

The prevailing Rocks on the Location" arc
the Syenetic and Greenstone Trap, thrown up
in immense dykes, running nearly in a north-
cast and southwest direction. These Rocks
are traversed by numerous Veins of (Juartz,
Calcareous Spur and Sulphate of Barytes.

VEINS.

The Veins on your Location, as is usual on
the North Shore of the Lake, arc much larger
than those found on the South.

Vein No. 1 is on the western point of the
Location.

Its course bears N. 34°. W. and S. 34°. E.
dipping 72°. E. It is four feet wide ; the
wall rock is Greenstone Trap. The greater
jiort of tills Vein is Calcareous Spar, but on
the east side of the Vein, being against the
wall rock, there is a portion of Sulphate of
Barytes about one inch thick.

On the west side of that, is Calcareous Spar,
four inches thick, separated from the larger
portion of the Vein, by Veinstone from four
to six inches thick.

On the inside of this, there is a thin portion
of highly crystiillized (Juiirtz, half an inch thick ;
on the west of tliis, is Calcareous Spar, eigh-
teen inches thick ; on tlu; other side of this is
Crystallized Quartz again as on the east side.
This (Quartz has a portion of Veinstone on its
west side from four to six inches tliick, fol-
lowed by Calcareous Spar, five inches thick,
being in contact witli the western wall-rock
of the Vein, a form of which will be given on
the plat of Vein.

In this Vein, I found Iron Pyrites,^ Spathic
Iron, with indications of Lead and Copper.

CROSS VEINS.

There are cross Veins intersecting this Vein.
The course of the first is N. 3G° E. four feet
wide; the second, one foot wide — course bears
N. 47°E. The third bears N. 31° E.; and
the fourth N. 51° I'L At the point, where
No. 1 and 2 Cross Veins unite with the miiii
North and South Vein, they form one large
Vein, eight feet wide.

VEIN No. 2.

Its course is N. 45° W. and S. 45° E. It
dips 80° to the east. This Vein is made up
of several small ones, that unite and form one
of ten feet wide between wall-rocks. This
Vein is mostly Sulphate of Barytes with some
Calcareous Spar, with indications of Copper.
Profet. or Mather reports to liave found Copper
in this Vein, while on an Exploring lixpedition
last Fall, for Mr. Prince. This Vein can be
traced to the opposite side of the hill.

VEIN No. .3.

This Vein is eight feet wide. Its course
bears N. 30° W. and S. 39° E. In this, we
found Spathic Iron with traces of Copper and
Lead. This Vein passes out of tlie Lake into
a cliff of rooks about 30 feet high, and run-
ning in this Rock about 20 rods, cuts directly
through an immense hill of Trap Rock, about
four hundred feet high above the level of the
Lake, and is found on the other side of the
hiU. If a shaft should be sunk on this Veim
at the side of the hill, and then drift into it,
there is every reason to believe that it would
prove rich in Minerals.

*MS

VEIN No. 4

l8 a few rods East of No. 3, nnd is three feet
wide ; its course boinp; N. 30" W. and S. 30° E.
dip 7f>" E., and is coiii])i)Sfd of Calcareous
Spar, interspersed witii Quartz.

VEIN No. 5

Is found on the iiortli side of tlio peninsula.
Its course boars S. 3«° W. Tills Vein is com-
posed of about equal i)arts of Calcareous Spar
and .Sulpliate of Jiaryk's. It is eight feet
wide at the top of the hi'!, about two hundred
feet back from the watui-, and three hundred
feet above the level of the Eal<e. It being
covered villi loose rocks on the shore, pre-
vented usfrom asccrtuiciin;^ its exact width at
the water, without besiowinir nio.'c labor than
we were prepared to do at the time; but judg-
ing from (he parts of tlie \'ciii exposed on the
top of tiic hill, we tiiduixiit it must be (en to
twelve feet wide at tlic Lake Sliore, as we gen-
erally find them to grow wider as they de-
scend.

This is a noble Vein and I woidd recom-
mend (liat an adit be opened into it nearly on
a level with the Luke, early in tlie spring or us
soon as (he Company may make arrangements
for practical Mining operations.

On the surface of this Vein I found a large
quantity of Spathic Iron.

This Mineral I hove found on the surface
of all the Veins that have been opened on the
North Shore of the Lake which contain the
Sulphurets of Copper.

VEIN No. e

Is 1^ inches ■wide. Its course bears S. 31° E.
composed of Sulphate of Barytes. Its wall-
rock is S) enetic Trap.

These Veins are all found on the peninsula
and form the greatest concentration of Veins
I have seen on the North Shore of the Lake.

There are many other small Veins or
"feeders " to the larger ones, which I do not
describe, as I report none that are less than a
foot -wide.

' 5

VEINS No9. 7 AND 8

Arc situated on the iiiiiin land about one
mile up the lliver, and Soutli of it ii mile and
a half. Thiy are in a ran-,'u of Greenstone
Trap Hocks cxtciidin-,' in a Southwestern
direction IVoui tlic mouth of tlie lliver as iar
as the eye can reach.

These Veins are coinposf^d of Calcareous
Spar, each one foot wide, with perpendicular .
wall-rock, and present a very good appear-
ance.

Mr. Gratiot forwarded to you .about four
weeks a"o, ii box of Specimens taken from the
diflereiir ^'eills. They are surface indications.

There are probably other vabuiMc Veliison
the Location whichhave not yet been disco-
vered, as the woods are tull of underbnisli,
and the rocks covered with soil and moss, so
that it is very hard to find thein only where
the rocks outcrop in the sides of the lull and
expose them to view.

In order to test these Veins I think'it will
be necessary to sink shafts on them, as they
arc jreolonicallv situated from forty to si.Kty
feet above the "rocks on the Locations where
Ores arc now found.

Should I find any new indications on ana-
IvsinK the Siwcimcns from this Location alter
my return east, you may hear i'rom ine again.

Respectfully your obedient servant,

J. F. BOYNTON,

Practical Geologist.
