Rice Lake Gold Belt, Manitoba -
Dunlop Option
Location
The Wallace-Dunlop Option is located on the west side of Wallace Lake
approximately 25 km east of the San Antonio Gold Mine at the town site of
Bissett in southeastern Manitoba. Access is by an all weather gravel road (PR
304) that intersects the southern part of the property. Boat access on Wallace
Lake is also possible. The property consists of 121 Ha of the Con 1 and Con 2
claims and 240 Ha of the Garner 2 claim, located further south at Gem Lake.
History
The area has been under claim by various owners since the early days of
exploration in the Rice Lake Gold Belt. Early work on the CON 1 and 2 claims is
summarized below:
|
1) |
|
1920s: discovery of gold
bearing material by W. Conley (numerous trenches); |
| 2) |
|
1932: Wallace Lake Mines
Ltd (Conley Mines Ltd) (8 drill holes); |
| 3) |
|
1936: Quebec Gold Corp.
(O’Brien Gold Mines Ltd) (6 drill holes); |
| 4) |
|
1945: Hudson Bay Mining
and Smelting (6 drill holes; 623 m); |
| 5) |
|
1979: Esso Minerals (5
drill holes; 1009 m) and magnetometer and horizontal loop survey;
and |
| 6) |
|
1999: Westshield
Consulting Ltd for Anne Dunlop: Conley Bay Shaft (prospecting,
stripping and mapping) |
Abundant visible gold in hand samples has been reported in grab samples from the
Conley shaft/trench with values over 1000 g/t, according to old newspaper
reports. Follow-up work has not been able to duplicate the high-grades. Silver
and minor copper have been reported as well as minor amounts of gold. Drilling
of the iron formation sequence ‘exhalite’ for base metal targets by Esso
Minerals in 1979 did not intersect significant copper or zinc mineralization.
Numerous gold occurrences were identified by Bill Conley during early
prospecting in the area north of the CON claims. Most of these are in quartz
veins and resemble some of the veins in the San Antonio Gold Mine. At the Conley
‘shaft’/trench on the Dunlop Option, the high-grade gold occurs with a
carbonate-silica unit that can be traced in a number of trenches for some
distance along the hinge of an open fold.
Geology of the Dunlop Option
According to reports by government workers the rocks that underlie the Dunlop
Option are the same age and composition as the Balmer Formation in the Red Lake
Gold Camp. These have been referred to frequently as the “Balmer Equivalent
rocks”. The rocks consist of a basement of felsic volcanic and felsic intrusive
rocks that are overlain by mafic and felsic volcanic rocks,
oxide-carbonate-sulphide-iron formation and younger mafic volcanic rocks and
clastic sedimentary rocks. Pillowed flows have been reported by several
geologists.
The ‘Balmer Equivalent rocks’ have been folded into a large open fold in the
central portion of the Dunlop Option. These structures are well-defined by oxide
iron formation that is closely associated with a ‘carbonate silica-rich’ rock
that has been variously described as dolomite, ‘limestone’, calcareous iron
formation and ‘alteration’.
The sequence faces southwards, but it is uncertain if it is downward facing or
not. Most units are near vertical and observed tops are towards the south or
southeast; early isoclinal folds have not been observed in this area.
A major shear zone cuts through the area along the south boundary of the Dunlop
Option and immediately south of the trenches on the CON 1 claim. This structure
has been traced by federal and provincial government geologists and interpreted
to be the same structure that cuts through both the Red Lake and Pickle Lake
gold camps.
Current Exploration Activity
To provide a geological framework for subsequent exploration the Company
undertook geological mapping on the Con 1 and Con 2 claims. A northern area of
felsic sedimentary rocks was documented flanked to the south by predominantly
gabbro with inliers of mafic volcanic and sedimentary rocks and iron formation.
At the contact of these two lithologic sequences there are beds of chert and
graphite representative of chemical sedimentation.
As an innovative approach to geochemical exploration for gold during the winter
the Company undertook the collection of 233 snow samples on the CON 1 and 2
claims in 2007. Soil geochemical surveys were also undertaken in the summer of
2007. A total of 183 soils were collected and analyzed.
The results to date on the property are indeterminate and additional sampling
will be undertaken to assess some of the 2007 responses. These surveys will be
undertaken subsequent to drill results obtained from the adjacent Lesavage North
property.
