1.0 INTRODUCTION

The DHC1 property (the “Property”) is located in the Cariboo Mining Division in east-

central British Columbia, Canada, centred at latitude 52°47’N and longitude 118°59’W,

approximately 20 km south-southeast of the town of Valemount (Figure 1). The Property is

located on NTS mapsheets 083D14 and 083D15, and TRIM maps 083D075 and 083D076.

A Property visit was carried out by the author to conduct a geochemical survey on the claim.

The survey consisted of the collection of 5 conventional stream sediment samples and 2 moss

mat samples from 5 sample sites.

1.1 PHYSIOGRAPHY AND ACCESS

Physiography of the Property is mountainous, lying on the eastern side of the Rocky

Mountain Trench. The lower slopes are steep and timbered along with some older clear-cuts.

The upper elevations of the property cover flatter terrain between several cirques. Abundant

talus is noted at the highest elevations. Relief of the Property ranges from 1,260 metres at the

logging road on Dave Henry Creek to approximately 2,500 metres at the mountain peaks.

Drainage is the region is generally dendritic, with all creeks on the Property draining into

Dave Henry creek.

Access to the Property from Valemount, BC is gained by traveling south on Highway 5

(South Yellowhead Highway) for approximately 2 km, then turning left onto Cedarside

Road which becomes the Canoe East Forest Service Road (FSR). Just past the 10 km mark

of the Canoe East FSR, a logging road branches left which heads up Dave Henry creek.

This road can be traveled for 8 km until a series of washouts in the road (Figure 2).

Currently, an ATV can traverse the washouts and cross Dave Henry creek approximately

2.5 km further up the road. The creek that drains the Property is approximately 3 km from

the washout or 500 metres from the crossing on Dave Henry creek. Alternately, helicopter

charters are available out of Valemount.

2.0 GEOLOGICAL SETTING

Geological mapping has been completed in the general area on a regional scale by Campbell

(1968) and Price and Mountjoy (1970). More detailed geological mapping has been

reportedly carried out in the general vicinity of the Property. A compilation of all mapping

has been presented on Map 2110A produced by the Geological Survey of Canada Map

(Murphy, 1991).

The rocks in this area are mapped as belonging to the Proterozoic age Miette Group, which

forms part of the Windermere Supergroup.

The Property itself straddles the contact of the Upper Proterozoic Lower Middle Division of

the Miette Group and the Lower Division of the Miette Group (Figure 3). The former consists

of commonly graded and locally cross-bedded quartzofeldspathic metasandstone, granule and

pebble conglomerate (grit), siltstone, grey-green silty phyllite, and schist. The latter is

comprised of mainly grits (quartzofeldspathic sandstone, grit and minor phyllite). The contact

is mapped as a thrust fault which appears follow the main creek draining the claim area.

Near the southwest corner of the Property, the Old Fort Point Formation of the Miette Group

is mapped (Figure 3). This formation is comprised of a triad of: upper dark grey to black

carbonaceous phyllite; middle, dolomitic and calcareous siltstone and phyllite; and, basal

green phyllite slate and locally calcareous quartz siltstone. This formation is used for

stratigraphic correlation within the Miette Group (Grasby, 1991)

3.0 WORK HISTORY

The only known exploration in the area of the Property consisted of the Regional

Geochemical Survey (RGS) conducted in 2005 for Geoscience BC. The current Property was

staked based on the results of a stream sediment sample (83D053003) collected during this

survey. This sample demonstrates anomalous values of rare earth elements (REE); in

particular: lanthanum (693.4ppm); cerium (1,120ppm); europium (20 ppm); samarium (116.0

ppm); terbium (16.0ppm); and, ytterbium (27ppm). The europium value represents the

highest concentration in the current BC RGS dataset. The multiple anomalous values of REE

suggest the presence of a common source.

4.0 EXPLORATION

4.1 SILT AND MOSS MAT SAMPLING

Field work was undertaken between September 28 and September 30, 2012. Exploration

consisted of collection of 5 silt samples and 2 moss mat samples from five sample sites. One

sample (34117) was taken to duplicate the historical regional geochemical sample

(83D053003) that precipitated the staking of the current Property. Further sampling was also

undertaken at selected locations higher up the creek, up to the first split of the creek into its

secondary tributaries that drain the upper elevations of the property.

Silt material was collected from trap sites along the creek banks. The material collected

appeared quite sandy so large samples (2–3 kg) were collected to ensure enough silt would be

available for analysis. At the two sites above the confluence of the secondary tributaries of

the main creek, moss mat samples were collected along with conventional silt samples. These

were collected as a means to check whether there would be an advantage in this type sample

media versus conventional silt samples.

Sample locations were GPS located where possible with a hand-held Garmin GPS12XL unit.

Flagging tape labeled with the sample number was also affixed to a nearby tree. Sample

coordinates are presented in Table 2. Figures 4 and 5 show the sample locations of the silt

samples and moss mat samples, respectively.

Both silt and moss mat samples were placed in a labeled polyethylene sample bag and sealed

with plastic tie locks. Samples were delivered to ALS Minerals (ALS) laboratory in North

Vancouver, BC. ALS carried out sample preparation and geochemical analysis. Sample

preparation consisted of drying and sieving the material to 180µm fraction (ALS preparation

code PREP-41, Appendix I). The remaining fraction has been retained for future use.

Sample decomposition was by lithium metaborate fusion and analysis for 38 elements by

induced coupled plasma with mass spectrometer finish (ICP-MS) (ALS analysis code ME-

MS81, Appendix I). This analysis specifically targets REE’s as well as other rare metals. A

prepared sample (0.200 g) is added to lithium metaborate flux (0.90 g), mixed well and fused

in a furnace at 1,000°C. The resulting melt is then cooled and dissolved in 100 mL of 4%

HNO3/2% HCl3 solution. This solution is then analyzed by ICP-MS. All elements are

reported in parts per million (ppm). The certificates of analysis is found in Appendix II.

ALS quality control consisted of routine use of standards, blanks and duplicates.

4.1.1 Results

A table of the key REE results are presented in Table 3. Results returned demonstrate that

anomalous values of REE’s are present in the creek, but most notably in samples 34111 and

34112, which were collected from the main creek below the first split (Figure 4). The sample

results from the secondary tributaries were significantly lower than sample 34112 collected

below the confluence. This strongly suggests that a possible source of the REE anomalies

may be very close to the location of sample 34112. The samples from the eastern split in the

creek (34113 and 34114) show slightly anomalous REE values as compared to the samples

collected on the western side (34115, 34116). Further investigation on the eastern slopes is

warranted.

Sample 34117, taken at the site of the 2005 RGS sample, demonstrated moderately anomalous

values, somewhat lower than the historical results. The historical results were determined by

neutron activation methods whereas the current results were determined by ICP-MS methods,

Neutron activation methods are likely to return more accurate values (pers comm, L. Bruce).

There is a fairly dramatic increase in the REE concentrations moving up the creek from

sample 34117 to 34111 and then to 34112. Between the latter two samples the concentration

effectively doubles in every analyzed REE element.

Moss mat samples 34114 and 34116 were taken at the same site as the convention silt samples

34113 and 34115 as a test to see if there was any advantage to this type of sample as

compared to convential silt samples. Comparison of the results shows very good correlation

of the values from the two sample media types which suggest that either sample type is an

effective means of testing the silt geochemistry. Sample locations and results of the moss mat

samples are presented in Figure 5.

5.0 CONCLUSIONS

The current claim was staked on the strength of multiple anomalous values of rare earth

elements (REE) in a regional geochemical survey (RGS) stream sediment survey conducted

for Geoscience BC in 2005.

Exploration was successful in confirming the presence of anomalous values of REE’s in the

silt of the sampled creek. Moreover, sampling above the original RGS sample showed

increasing concentrations of all analyzed REE elements until the first split of the creek into its

secondary tributaries.

Analysis of the convention silt samples and moss mat sample pairs demonstrated very good

correlation between analytical results. This indicates that either sample media should be

adequate for sampling purposes.

The lithium metaborate fusion is not the preferred method for the determination of base metals. Many sulfides and some metal oxides are only partially decomposed by the borate fusion and some elements such as cadmium and zinc can be volatilized.

Base metals can be reported with ME-MS81 for either an aqua regia digestion (ME- AQ81) or a four acid digestion (ME- 4ACD81). The four acid digestion is preferred when the targets include more resistive mineralization such as that associated with nickel and cobalt
