Access and Location
The Wekusko/Ferro gold property is located on the east side of Wekusko Lake,
20 km east of the mining community of Snow Lake, Manitoba (Figures 1 and 2).
Access is provided by boat in summer, 12 km across Wekusko Lake. In winter
the property is easily accessed via snowmobile or via 4x4 truck on a winter road
across the same lake. In summer ATV's provide access to much of the property
via a series of drill roads and old trails, from the main camp at the Ferro mine
site, 5 km east of the Herb Lake dock. More remote parts of the property are
accessed via floatplane located at Snow Lake, which can fly into Roberts Lake or
Johnson Lake, near the NE edge of the Wekusko property.
Description of Property
The Wekusko/Ferro property covers 9,082 ha (22,441 acres) and consists of 57
claim blocks. All claims are in good standing and are held by Strider Resources
Limited (or by D.V. Ziehlke, in trust for Strider Resources Limited).
Regional and Local Geology
The Wekusko property occurs at the eastern end of the prolific Flin Flon - Snow
Lake volcanic belt. The property is underlain by a series of Missi Group volcanic
rocks that overlay older Amisk Group volcanic and metasedimentary rocks. The
Missi volcanic sequence occurs in a large synformal fold structure that covers the
central portion of the property (Figure 3). Several types of felsic to mafic plutonic
rocks intrude both the Missi and Amisk group rocks.
A major fault, the Crowduck Bay fault (CBF, Figure 3), has been traced for more
than 100 km to the SW under Paleozoic cover rocks, indicating that this structure
is a major crustal break. Secondary faults, off this major structure, occur on the
Wekusko property, and are associated with significant gold mineralization. Two
main regional zones of gold mineralization occur on the Wekusko property, the
Laguna trend and the Ferro trend.
The Laguna trend consists of a number of gold showings, including the past
producing Rex-Laguna mine, near the east shore of Wekusko Lake, that extend
at 045 to 050 degrees Azimuth, 8 km to the McCafferty gold vein. Work over the past 15 years has extended this gold belt, with new gold occurrence discoveries,
at least another 6 km to the NE.
The Ferro trend occurs in the vicinity of the Ferro gold mine and extends in both
directions along the fold axis of a major synformal structure. Numerous gold
showings are present over more than 2 km along this NE trending structure,
including the Gold Dust zone, a significant new blind gold deposit discovered by
drilling in 1989.
These two gold bearing trends are considered to have excellent potential to
contain additional blind gold deposits.
Target Commodity and Deposit Types
The target of continued exploration on the Wekusko property is epigenetic,
mesothermal, orogenic type gold deposits, structurally controlled, associated with
secondary or tertiary splay shear structures off the main Crowduck Bay fault.
Early prospecting work, which discovered all the gold showings to date, (except
for the recently discovered Gold Dust Zone), made these discoveries on exposed
outcrop. Exploration work in the Snow Lake area, over the past 17 years
indicates that these quartz vein type gold occurrences, located on outcrop, are
often minor secondary fracture fillings spatially related to much larger gold
bearing shear zone structures located in nearby larger scale, linear depressions.
Application of this theory in 1989 resulted in the discovery of the recessive
lineament hosted Gold Dust Zone, which has been traced for 1.8 km metres? along
strike.
Summary of Previous Work and Production
Early prospecting in the 1920's and 1930's resulted in the discovery of numerous
gold occurrences in the vicinity of the two main gold trends, including the Rex-
Laguna and Ferro mines. The Rex-Laguna mine, which occurs just outside the
present Wekusko property boundary, operated intermittently from 1924 to 1940.

The Ferro mine, the Rainbow, and nearby gold showings were discovered in
1923 to 1926. Stockwell (1937) provides detailed descriptions of all known
occurrences in the area. The Ferro mine was developed with a 543 ft. shaft and 4
levels of drifting in the ore from 1940 to 1947, when due to financial difficulties,
the operation was shut down before commercial production was achieved.
In 1982, Noranda staked the Nor claims over much of what is now the Wekusko
property, and did some trenching, as well as limited IP geophysics along part of
the Laguna trend, with limited success. Strider Resources Limited started acquiring property in the Wekusko area in 1988, with the staking of the Ferro
mine site, and has done periodic prospecting and additional exploration since
that time.
Ferro Mine Area
In 1988, Strider Resources Limited staked the Ferro Mine and optioned it to
Pierce Mountain Resources Limited. ProRoc Explorations Inc., the consulting
division of Strider Resources Limited, directed the project on site. After acquiring
the surrounding property, Pierce Mountain drilled 37 holes totaling 3,708.5m
(12,167 ft.) within the Ferro mine structure, plus 19 holes for an additional
2,014.7m (6,610 ft.) in the newly discovered Gold Dust Zone. In addition over
300 km of line cutting, magnetometer, and VLF-EM surveying were completed by
Pierce Mountain and limited partner Placer Dome Inc. from 1988 to 1990.
In 1995, Golden Tag Resources Ltd. of Montreal optioned the Ferro - Wekusko
property from Strider and completed 918m (3,014 ft.) of large diameter, reverse
circulation drilling in the Ferro and Gold Dust Zones.
In 1997, line cutting, VLF-EM and magnetometer surveys were conducted over
part of the Jake-3558 claim, followed by 766m (2,514 ft) of drilling in 8 holes, by
Rodera Diamond Corp. of Vancouver. Geological mapping was also conducted
over this ground at the same time. This work resulted in the discovery of a new
zone containing 8 grams gold over a 0.5 metre interval within a wider shear zone
of 12.5 metres of 0.56 grams gold. This is along the Rex-Laguna/McCafferty gold
trend and extends this mineralization over a total strike length of 13 km. In 1998,
AMT International Mining Corp. continued this work on the Jake claims, with a
limited IP survey in the same area. No work has been done in that area since.
In 1997, AMT International Mining Corp. of Tucson, Arizona optioned the Ferro -
Wekusko property and drilled 3,173.3m (10,411 ft.) on the Gold Dust Zone before
withdrawing from Canadian exploration in 1999. At that time the drill inferred
resource at the Gold Dust Zone was ~ 115,800 tons of .30 oz/T gold. Calculated
resource at the Ferro mine is 87,741 tons of .422 oz/T Gold (Ash and Associates
Consulting Ltd., 1992). These estimates are considered historical and are non NI
43-101 complaint.
In 1995 and 1996 Strider Resources, with the aid of Dr. M. Fedikow of the
Manitoba Geological Survey, conducted tag alder biogeochemical surveys over
the drift covered Gold Dust Zone to determine if this method could be used to
locate gold bearing zones in covered recessive lineaments. The results were
positive, with molybdenum, arsenic and gold responding in tag alders to the Gold
Dust mineralization (Open File Report OF99-14, MB Industry, Trade and Mines
publication by M.A. Fedikow and D.V. Ziehlke, 1999).
In 2001, Vital Pacific Resources Ltd. optioned the Wekusko property and
commissioned flying of new orthogonal digital air photos over the property.
1:5000 scale photos and 2 metre contour base maps were constructed from the
orthogonal air photos. In 2002, a limited tag alder survey was conducted in the Chickadee Lake area, on behalf of First Majestic Resources Corp., which
indicated a number of weaker responses several kilometres along strike of the
Ferro mine area to the southwest. Subsequent drilling of 963metre(3,159 ft.) in 11
holes in January 2003, intersected anomalous but not ore grade mineralization.
This work suggested that higher magnitude tag alder responses were required to
indicate significant gold mineralization. This valuable information will aid in
evaluating future tag alder survey results in the Wekusko property area.
The Gold Dust Zone
In July 2004, Strider Resources Limited conducted additional tag alder sampling
along the northeast extension of the Gold Dust Zone, and in the vicinity of the
McCafferty gold deposit.
The tag alder sampling returned significant molybdenum, gold and arsenic
anomalous responses over 700 metres northeast of the exposed Gold Dust
mineralized zone.
Prospecting and reconnaissance mapping in the vicinity of the McCafferty zone,
completed in conjunction with the tag alder sampling, indicated the presence of
additional sub-parallel quartz veins near the McCafferty gold vein, up to 400
metres away. These minor veins are often mineralized with minor pyrite,
pyrrhotite, tourmaline and arsenopyrite, similar to the McCafferty deposit. These
veins are often adjacent to parallel recessive zones, some of which are
coincident with magnetic lows and VLF-EM conductors. A number of tag alder
anomalies were also returned from this work, which upgrades VLF-EM anomalies
to drill worthy targets.
In the autumn of 2006, Black Pearl Minerals received permission to extract, by
open cut methods, and to process up to 9,100 tonnes of ore from the Gold Dust
Zone of its Wekusko Lake Gold Property.
In November 2007, Black Pearl mobilized heavy equipment onto the property,
constructed a 16-man operations camp, stripped cover and overburden from the
targeted zone and mapped and sampled the Gold Dust vein preparatory to
blasting and stockpiling. Channel sampling was successful in locating the goldbearing
portions of the veins and the assays from the blast holes were used for
grade control. Selective stockpiling of vein material began in late November. This
program in ongoing.
The purpose of the program is to characterize the geological and metallurgical
nature of the upper portion of the Gold Dust ore shoots to gain important
information for the possible full-scale exploitation of the deeper Gold Dust Zone
and other known zones on the property including the Ferro and McCafferty. The
bulk sample program will investigate and stockpile vein material from areas
defined by the following drill holes completed by the Company during winter
campaigns in 2005 and 2006 and by previous operators.
