SUMMARY:
Bryan Kirkness of Kirkness Pacific Holdings Ltd has developed a rock quarry on the
subject mineral claims. Testing of the rock has been done and indicates good quality
material is present. Rock Sampling was conducted by RM Resource Management Ltd on
a potential expansion area for the quarry for the purpose of testing rock aggregate quality
and to check for any unusual mineral concentrations. Sampling of an area of glacial
outwash gravels was also done to check for the presence of gold in the gravels and to do a
screen analysis on these gravels. A geological analysis of some glacial tills in an area
where a creek channel may be realigned has also been carried out. Total cost of these
work progams is approximately $13,700. This assessment report summarizes results of
the sampling, assaying and technical studies done. This work was carried out during the
period May 2006 to May 2007.
LOCATION AND ACCESS: (Figure 1)
The property is located approximately 7 km south-west of Chilliwack and about 1.5 km
north-west of Cultus Lake. Access to the site is from Chilliwack via Cultus Lake Road to
Parmenter Road and then via approximately 2 km of private roads on the mineral claims.
LAND TENURE AND CLAIM STATUS: (Figure 1)
Lot 820 New Westminster Land District.
Mineral Tenures 512638 and 534087 including 31 Mineral Claim Cells
containing 655.87 Ha, registered in the name of Bryan Kirkness
TOPOGRAPHY:
The general property topography is southerly and easterly sloping with intermittent
hummocks, benches and gullies. The quarry area and associated mineral claims are
situated just east of the peak of Vedder Mountain on an east-west trending ridge between
approximately 100 and 400 meters elevation. The property is fairly widely covered with
soil and glacial till overburden ranging up to 1 or 2 meters deep with local deeper
deposits in the valleys. The quarry site itself is covered with minimal soil and overburden
generally less than one meter thick and locally interspersed with rock outcroppings.
VEGETATION AND TIMBER:
The area is covered with minimal scrub growth, mostly deciduous trees, including
willow, alder, poplar and maple with some fir and hemlock.
GEOLOGY: Figure 2
Regionally the area is underlain and surrounded by four Formations. To the north of the
claims lies the Chilliwack Group described as Devonian to Permian undivided
sedimentary rocks. To the south of the claims is the Kent Formation which consists of an
Upper Jurassic mixture of conglomerate and c o m e clastic sediments. East of the Kent
Formation and on the southeast comer of the claims is the Cultus Lake Formation which
is a late Triassic to Early Jurassic sequence containing mudstones, siltstones, shales, and
other fine clastic sedimentary rocks. Immediately underlying the claims and forming the
main host for the rock quarry is the Vedder Mountain Metamorphic Complex which is
3
Permian in age and described as a sequence of lower Amphobilite to Kyanite grade
metamorphic rocks.
The Vedder Mountain Formation metamorphic rocks are the predominant rock formation
on the property and the main rock type of interest. In the area currently being explored
they consist of a mixture of grey to green metamorphosed basalts and andesitic rocks.
Rock conditions are generally massive and competent and are locally cut by northeasterly trending by south-easterly dipping shear and fault structures.
Locally the rocks are intensely sheared into an almost braided pattern. Basalts vary from
massive to an interlayered mixture of basalt and quartz-carbonate banding. When present
the quartz carbonate ratio is dominantly quartz with minor carbonate. The andesites are
sheared in a similar geometry to the basalts but with very little quartz-carbonate banding.
The contact between andesites and basalts was not exposed in the area examined.
EXCAVATION AND SAMPLING
-Sampnilg
A new road was constructed during the latter part of May 2006 into a proposed expansion
area for the Vedder Mountain Rock Quarry, as shown on Figure 4. This road was
constructed largely using a John Deere 450 Excavator. The area is covered by vegetation
and intermittent to continuous overburden ranging from nil to several meters thick. Three
sites were stripped for sampling (See Photos 1,4,6).
Rock samples were taken from these three locations on April 30,2007 (Figure 3). The
purpose of this sampling was to examine the rock chemical characteristics and measure
ABA (acid generating potential) for purposes of aggregate quality analysis and at the
same time do a multi element ICP check for any significant concentrations of specific
elements that might be present in the rocks. The mineral property owner was particularly
interested in any potential for precious or base metals.
Rock sample descriptions are as follows. Sample locations are included in
Appendix I1 - Table 1.:
KPO701- Massive sheared and metamorphosed basalt, predominantly grey-black in
color, with minor epidote and quartz+/-carbonate veining. (Photo 2) There was evidence
of strong shearing presenting a braided texture. An approximate NW strike with a
roughly 30' SW dip to the grain of the rock was observed.
KP0702 - From the same location as sample 01, this sample was similar to sample 0 1
except that this rock included up to 75%quartz +/- carbonate layering within the sheared
grain of the rock (Photo 3). These quartz-carbonate rich zones occurred intermittently
within the exposed area of the outcropping and appeared to constitute less than 25% of
the total rock makeup of the visible area.
4
KPO703 - This sample was situated about 300 meters south west of samples 01 & 02 and
has a similar sheared braided texture as the first samples but was light-green colored
metamorphosed andesite (Photo 5). Only minor quartz-carbonate veining was present.
KP0704 - This sample site was situated a fbrther 150 meters to the SW. The rock at this
location was the same massive, grey, sheared, braided textured basalt as was found at
location 01 but contained extensive limonite staining although no pyrite sulphide
materialization was evident (Photo 7).
Soil Sampling
The property owner has also opened a gravel area for aggregate use and wanted to know
if there was any gold potential in these gravels (See samples KPO709-10 locations on
Figure 3) These gravel are glacial outwash deposits scowered from nearby mountains..
A test pit was excavated into this location for sampling (Photo 4) from which “soil
samples” were taken. Soil sample description is as follows. Sample location is included
in Appendix I1 - Table 2.:
KPO709 & 10 - These gravels ranged from clays to fine sands to coarse sand and
cobbles. The cobble component on average makes up less than 50% of the overall
material mix observed in the area. Cobbles are predominantly composed of a mixture of
andesite, basalt and dioritic rocks.
Till Sampling;
Bryan Kirkness hired Pottinger Gaherty, Environmental Consultants (PGEC) to
undertake work on evaluation of a realignment of Hatchery Creek which crosses the
mining claims. PGEC subcontracted the geological evaluation of glacial till deposits to
Northwest Hydraulic Consultants (NHC) under the direction of Malcolm Leytham. This
field work was carried out on April 9,2007 and evaluation was conducted in early May
2007.
Four test pits (NHC-TP-01 to 04) were dug over the proposed area along about 300
meters of the creek valley to test the continuity and permeability of the glacial till
deposits (Figure 3).
RESULTS OF TECHNICAL ANALYSIS
Assaying
Sample analysis was done by Chemex Labs. Standard rock sample preparation
procedures were used. Multi-element ICP analyses including for gold were made. In
addition ABA analyses were also done to get a rough idea of the acid generating
characteristicsof the rock. Results of rock sampling analyses are shown on Table 1
(Appendix 11).
No significant base or precious metal values were obtained from the rock samples. Fe
values were higher than expected and ranged from 3.2 % in the andesite to 4.2% in the
iron stained basalt. The lowest Fe value at 1 . 6 % in~ the
~ quartz-carbonate rich basalt
sample. A fairly high Ba value of 1550ppm occurred in the quartz+/-carbonate rich basalt
5
sample suggesting the presence of some Barite. Calcium was highest (2.7%) in the
andesitic rock.
The soil (gravel) samples were also analysed using standard soil sample preparation
procedures and multi-element ICP analyses. Both samples were combined together for
this analysis. In addition a screen analysis was done on these samples to get a rough idea
of the proportion of the sand component. The gold assay indicated a very low 0.003 ppm
content. The screen analysis indicated 15% sand (1mm to 2mm) and 20% fine sand (1mm
to 150 microns) and a very low silt-clay component of 3%. Results of these analyses are
shown in Appendix I1 - Table 2.
Rock Ouality Analysis
A technical review of rock samples fiom location KP0701/02 of the proposed quarry site
expansion area was undertaken by Levelton Consultants under the supervision of Jim
Place P. Geo. Samples KP0701 & 02 were combined for a total of approximately 15 kg
of rock used for this testing program. Testing was done in the laboratories of Levelton
Consultants in Richmond BC and at Chemex Laboratories in North Vancouver BC. Tests
undertaken included:
0
Acid Base Accounting (Appendix I1 - Table 1)
Micro Deval Abrasion Test (Appendix 111)
Magnesium Sulphate Soundness Test (Appendix 111)
Sand Equivalent Test (Appendix 111)
The ABA values suggest a non- or low-acid generating potential. The NP:MPA ratio for
all samples was above 2 which is the normally accepted threshold for acid to non-acid
generating character. Sulphide sulphur was also low and pH was above 7, both further
suggesting low acid generating potential.
The Micro Deval test approximates the durability and resistance to degradation of the
rock. This test suggests the rock to be within normal limits for degradation.
The Magnesium Sulphate Soundness test is primarily to check for the resistance of the
rock under freeze-thaw conditions. The rock showed low quality under this test.
The results of the Sand Equivalent test indicates the rock is of very high Sand Equivalent
Value of 94 suggesting good quality with respect to this aspect, producing very limited
fine clay particles.
Glacial Till Testing Program
Results of this work are described in a short report included in Appendix 111.
CONCLUSIONS AND RECOMMENDATIONS
1. The ICP analysis indicates no significant concentrations of base or precious metals in
the samples taken. Of the 36 elements analysed for only barium showed somewhat
elevated levels.
6
2. No gold values of any consequence were found in the glacial gravels examined. The
screen analysis suggested a 15% proportion of sand component (lmm to 2mm size
range) within the gravel materials.
3. This aggregate rock sample technical review suggests that the proposed expansion
area for the quarry can produce, under certain circumstances, sound and durable
aggregates that are not likely to create acid runoff when exposed to the environment.
The reader is cautioned however that these are very preliminary results based on
limited sampling. More extensive testing should be done using a larger number of
samples taken over a wider area if it is planned to quarry the area described by this
report.
4. The glacial till study is still in progress however geological analysis work to date
indicates the presence of low permeability tills in the area tested.
5 . Total cost of this work program is $13,738.38 (Appendix I)

Test Pits
nhc is investigatingthe potential to re-align an approximately 300 m reach of Hatchery Creek to
reduce the risk of avulsion and to allow establishment of a riparian zone. The preliminary
concept is to construct the channel in the native till layer at the base of the existing road prism on
the south side of the area recently filled by overburden. The expectation is that the till layer
would have low permeability, limiting seepage loss fiom the channel. Preliminary investigation
of subsurface conditions was conducted on 9 April 2007 with the excavation and inspection of
four test pits along the proposed new alignment of the creek.
Test pits were dug along the proposed alignment spaced roughly 60 m apart. The first test pit,
located roughly 20 m downstream of the asphalt flume, revealed a 2 m overburden cover of loose
brown sandy-gravel over a hard grey sandy-loam. The test pit was dug an additional metre
deeper without exposing bedrock or change in material.
The second test pit, located 64 m downstream, exposed the native sandy-loam till only 0.3 m
below existing grade. However, a test pit dug less than 10 m further downstream, revealed over a
metre of overburden. Test pit two was also extended an additional metre below the top of the till,
uncovering no further changes in material.
The third test pit, located 1 15 m downstream fiom test pit 1, had a 0.3 m thick layer of sandygravel overburden, followed by a 0.2 m layer of grey sandy-loam, and a 1 m thick layer of brown
sandy-gravel before the grey sandy-loam till was exposed - roughly 1.6 m below grade.
Excessive seepage was present from surface down to the gravel-till interface. The test pit was
extended an additional 1 m.
The fourth test pit, located 185 m downstream from test pit 1, was plagued with excessive
seepage and saturated slumping from grade down. The road is only 1 m above the grade north of
the road, but the sandy-loam till layer was located roughly 3 m below grade.
All four test pits showed no sign of seepage in or out of the till, however the lower two test pits
experience significant incoming seepage. The lower two test pits appeared to indicate a relatively
horizontal till surface, whereas the upstream most two pits indicated a north sloping till surface,
sloping at roughly 5%. A rough hydraulic conductivity seepage test was conducted adjacent to
test pit 2. It suggested a hydraulic conductivity in the expected range of 10E-8 to 10E-10 m/s.
This value should be considered a rough approximation.

The cost of conducting this work, excluding the cost of excavator and operator, was $3,846.31.
