Introduction The mineral exploration licence #017823M consists of 10 claims and is located within the western
portion of Notre Dame Bay, north-central coast of the island of Newfoundland. This licence property
includes the northeastern edge of the town of St. Patricks (Figure 3); and is located 8 km northeast of
the town of Springdale, and 3 km southwest of the town of Little Bay. The license #017823M area
lies within the 1:50,000 scale NTS topographic map sheet 2E/12 (Little Bay Island), (Figure 1). The
northeastern corner of the property is situated at UTM coordinates 5492500N and 575000E (Figure
3). Prospecting and rock sampling was carried out over 2 days on the license #017823M.
Approximately 60% of the property is located on the south side of Little Bay and is only accessible
by boat therefore only the northern property was prospected at this time. The purpose of this
exploration work was to conduct a reconnaissance examination of outcrop and identify any visual
mineralization in the property, collect representative samples for analysis, and provide a very
preliminary assessment of the economic potential of the property.
Location, Access and Topography
The south western portion of the exploration license area #017823M is intersected by the highway
Route 392 (Figure 3), which branches northward from highway Route 390 at a junction 3 km west of
the town of Springdale. The topography within the licence area #017823M consists of gently
inclined slopes extending southward from highway Route 392 to a well-exposed shoreline with
gravel and cobble beaches. Northward of this highway, the topography is somewhat rougher, with
steep slopes covered in intensely fractured/broken (felsenmeer-like) rock with periodic outcroppings
of more massive rock. Shrubs and small trees occur in clusters along the steepest slopes while a
thicker growth of mixed coniferous forest occurs towards the western portion of the property.
Outcrop exposure is moderate throughout most of the license #017823M area; with best exposures
occurring along the shoreline where vertical cliffs of outcrop ranging up to 10m in height in a few
localities.

Regional Geological Setting
The mineral exploration licence#017823M area is underlain by Cambrian to Ordovician submarine
mafic to felsic volcanic rocks of the Lushs Bight Group, and lies within the Notre Dame Subzone of
the Dunnage tectonostratigraphic zone; (Figure 2). The Lush’s Bight Group defines an ophiolite
stratigraphy and may represent remnants of oceanic crust. The Lush’s Bight Group is structurally
bounded to the south and east by the Lobster Cove fault and to the northwest by the Green Bay fault.
The Lobster Cove fault juxtaposes the Lushs Bight Group against the Silurian Springdale Group and
the Ordovician Roberts Arm Group to the south. The Lushs Bight Group forms part of the Notre
Dame Bay nappe that forms the structurally highest nappe in the Notre Dame Subzone. The Lush’s
Bight Group has previously been interpreted to be oceanic basement to the Dunnage zone; however,
work in 1995 by Kean suggests that the Lushs Bight Group was formed in a suprasubduction zone.
The Lushs Bight Group can be divided into a number of fault-bounded blocks defined by the
intersection of north-northeast- and northeast-trending faults. The license # 017823M falls within
one of these major structural blocks and consists of a single major stratigraphic unit (i.e.: pillow
lavas). Those rocks outcropping within the licence # 017823M area consist of fine grained to
aphanitic, grey to dark green, strongly epidotized basaltic pillow lava with minor to extensive,
unseparated common diabase and gabbro dykes and sills with minor tuffaceous rocks and chloritic
schist as well as intercalated, bedded, mafic tuffs and massive flows.

Historic Exploration Work The Dunnage Zone is of prime importance to economic geologists as it plays host to an abundance
of significant VMS and epigenetic gold deposits and occurrences. The Lush’s Bight Group itself
contains approximately 100 volcanogenic base-metal sulphide occurrences, showings and prospects
.Two of these major sulphide and gold occurrences (i.e.: Little Bay Mine - #16 and Hearn Prospect-
#17) are situated just 3 km to the northeast and within the same lithological unit as underlies the
mineral exploration licence #017823M area . The Little Bay Mine operated from 1878 to 1894 and
1898 to 1901. An estimated 180,000 tonnes of 2.5 % to 10% Cu ore was produced from the ine.
Exploration of the property by various companies continued periodically from 1902 through to 1969
with the final period of production from 1961 – 1969 resulting in 2,571,977 tonnes grading 0.8% to
2% Cu and 195 kg Au. The mine closed in 1968 with reserve estimates of 267,000 tonnes averaging
1.02% Cu. The Little Bay deposits occur as massive, steeply plunging lenses and pods, as
disseminations, as veins and veinlets of pyrite and chalcopyrite, and as sulphide-bearing quartz veins
in northeast-trending and steeply dipping chloritic schist shear zones within mixed pillow basalts
and diabase dikes.
The Hearn prospect consists of Au + Cu, Zn, Pb-bearing quartz-pyrite veins, bands and
stringers within sheared and brecciated chloritic schist hosted by pillow lavas and diabase dikes
(Dean, 1977). This northeast striking and steeply dipping mineralized shear zone is traced
intermittently over 1200m (MODS, 002E/12/Au001). The exploration history is briefly summarized
as the discovery of gold-bearing quartz veins in 1932, followed by trenching and drilling in 1941 and
drilling and geophysics in 1963-64 with the best reported gold intersections of 0.045 and 0.07 oz/ton
Au over 0.15m and 0.52m, respectively (MODS, 002E/12/Au001).

The area encompassed by the mineral exploration licence #017823M contains two known mineral
occurrences; the Shoal Harbour West pyrite occurrence (MODS, 002E/12/Pyr027) and the Shoal
Harbour pyrite occurrence (MODS, 002E/12/Pyr028). The Shoal Harbour West pyrite occurrence,
located at UTM coordinates 574340E / 5491290N, is classified as an indication and described as
small shaft dated from the late 1800’s with no additional information. The Shoal Harbour pyrite
occurrence, located at UTM coordinates 574700E / 5491420N, is classified as an indication and
described as small shaft dated from the late 1800’s with no additional information.
A 1997 exploration program by Canaco Mining Resources collected samples from the old workings
at Shoal Harbour West showing. The samples consisted of disseminated and stringer chalcopyrite in
a chlorite schist. Assays from rock samples were encouraging with elevated gold (43ppb), copper
(467ppm), and Zn (0.47%) values. The results of the soil survey were also encouraging with the
analysis for Cu revealed values greater than 50ppm, two of which were greater than 100(up to
maximum of 274ppmCu). A cluster of these anomalies, with coincidental Zn, was recorded
southwest of Shoal Harbour in the vicinity of Shoal Harbour and Shoal Harbour West pyrite
showings. Another significant value of 580ppmAs was obtained from samples which also assayed
anomalous copper and zinc near the Shoal Harbour pyrite showings.
Prospecting Results
Prospecting was conducted in 2011 over the area underlying the mineral exploration licence
#017823M (Figure 1). The outcrop throughout the area consists of very fine to fine grained, very
dark green to green-gray-black, variably chloritized and sheared mafic volcanics of the Lushs Bight
Group; including dominantly basaltic pillow lava with minor to extensive, unseparated diabase and
gabbro dykes/sills and minor intercalated tuffaceous rocks. The volcanic rocks are intensely sheared
and fractured throughout the property yielding rubble scree slopes along shoreline cliff exposures.

the 9 mineralized grab samples collected from outcrops did not return any elevated values.
Conclusions and Recommendations
The licensed area prospected in 2011 was on the north side of Little Bay. This was due to ease of accessibility. The other portions of the license is located on the south side of Little bay which would require a boat. The areas prospected in 2011 did not return any encouraging results. Future prospecting should be focus on locating the Shoal Harbour and Shoal Harbour West showings on the south side of Little Bay. 10
