Previous Work and Mineralization
The area has a long history of mining and mineral exploration beginning in 1881 with the opening of the Pilley’s Island pyrite mine.
22468M
Approximately 450,000 tonnes of pyritic ore were mined between 1881 and 1908. Since than a number of companies, including
Legend
Frobisher Mines, Brinex, Brinco, Consolidated Morrison Exploration, Phelps Dodge and Altius Resources have explored the area.

There are seven historic mineral occurrences on the property (Map 2), the Bouzane Shaft, Bull Horn Prospect, Bull Road Extension,
Freeman's Claim, Henderson Showing, Mansfield and Strickland prospects.
Map 2: Claims Location and Regional Geology
The Henderson Showing consists of a chaotic mixture of massive, rounded clasts of massive pyrite, Cu, Pb, and Zn sulphides up to 1 m
EARLY TO LATE SILURIAN
in diameter and fragments of rhyolite, chert, and basalt in a breccia exposed over a width of about 20 m (Tuach, 1990). The breccia is strongly altered, contains
SPRINGDALE GROUP
disseminated pyrite and has been traced inland for approximately 100 m. The sulphide blocks display banding and colloform textures and contain 2 - 3% Cu with
minor Zn and Pb (Epp, 1983).
EARLY ORDOVICIAN TO LATE DEVONIAN
The Bull Road Extension consists of stockwork "feeder" type mineralization with networks of veinlet and disseminated Cu-Pb-Zn sulphides.
EARLY TO MIDDLE ORDOVICIAN
At the Bouzane Shaft, mineralization consists of pyrite and chalcopyrite in dacitic tuff (Dean, 1977).
ROBERTS ARM GROUP
Epp (1983) described the Mansfield Prospect as consisting of stockwork feeder-type mineralization with veinlet and disseminated base metal sulphides (pyrite,
chalcopyrite, galena and sphalerite) within highly silica/sericite/clay-altered and brecciated rhyolitic host rocks. The showing actually consists of two occurrences a northern occurrence rich in copper and zinc, and a southern occurrence showing an appreciable increase in lead and an accompanying decrease in copper and
zinc (Epp, 1983).
CUTWELL GROUP?
The Strickland occurrence is hosted by polylithic fragmental horizons that contain rounded clasts of massive pyrite, with Cu-Pb-Zn sulphides (Epp, 1982).
Mineralization also consists of pyrite in silicified, pyritized pillow basalts (Dean, 1977).
The Bull Horn Prospect is hosted by agglomerate/conglomerate horizons, which contain fragments of massive sulphide in a dominantly dacitic and basaltic
breccia. Mineralization consists of chalcopyrite, galena and sphalerite. This fragmental zone may be
related to the Bull Road zone located 150 m farther southeast (Harris, 1976). The weighted average of Highlights:

Important Adjacent Prospects
The 3-B Zone (discovered in 1983), metres from the northern boundary of the property, is estimated to contain 200, 000 to 300, 000 tonnes of 3 to 4% Cu, 1% Zn and 20 to 30 g/t Ag (Epp et al.,
1984: Arnt, 1988). The mineralization is hosted by pervasively sericitized felsic volcanic rocks. Drilling adjacent to the zone in 1989 intersected 2.74 m grading 6.4% Cu, 0.46% Zn, 11.28 g/t Ag
and 0.85 g/t Au (Tuach, 1989). Drilling to test the down dip extension intersected 16.77 m of massive and stringer sulphides assaying 1.84% Cu, including 4.42 m of massive sulphide
containing 4.42% Cu. Another hole intersected 2.29 m of massive and semi-massive sulphide, which assayed 7.6% Zn, 0.39% Cu, 30.72 g/t Ag and 10.48 g/t Au. The zone is interpreted to
extend south under Bumble Bee Bight.
The Bull Road showing (about 250 m north of the property), which was discovered by Brinex in 1967, was exposed in five trenches and tested by diamond drilling. Indicated reserves were
estimated at 27,377 tons grading 2.00% Cu, 0.52% Pb, 5.02% Zn, 0.62 oz/t Ag and 0.008 oz/t Au (non NI 43FOR MORE INFORMATION CONTACT: 101compliant).The mineralization is hosted by re-sedimented, polylithic breccia that is analogous to the breccia ores at
Buchans.
Mineralization in the Pilley’s Island Cu Mine (250 m west of the property) consists of massive pyrite and chalcopyrite with
minor sphalerite and galena (Tuach, 1990). A Zn-Au rich massive sulphide intersection from diamond-drill hole 42, assayed

Mineralization Model
Three genetically-related styles of volcanogenic mineralization are recognized on Pilley's Island. These are stockwork
October, 2014
stringer mineralization, in situ stratabound massive ore and gravity-transported/reworked distal deposits. These ores are associated with rhyolitic/dacitic domes and are
interpreted to represent mineralizing events during the waning phases of volcanism in an island arc setting in the Upper Ordovician/Lower Silurian (Epp, 1983).
Analogies have been drawn between the Pilley’s Island and the very high grade Buchans (16.2 million tonnes at > 23% combined Cu-Pb-Zn-Ag-Au) VMS deposits. Recent revisions to the
geological interpretation of the area, and the presence of an extensive alteration system suggests the potential for further discoveries (Evans and Vatcher, 2009).
