1.0 INTRODUCTION The DHC 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 20 soil samples and one stream sediment sample.

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, which in turn flows into Kinbasket Lake, the reservoir formed by the Mica Dam. The Property is located south of the town of Valemount, BC, which is located along the South Yellowhead Highway (Highway 5). Access to the Property from Valemount is gained by traveling south on Highway 5 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 and heads up Dave Henry creek valley. This road can be traveled for 8 km until a series of washouts in the road are encountered (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. Alternatively, 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 Prior to the author’s work in this area, the only known exploration in the area of the Property consisted of the Regional Geochemical Survey (RGS) conducted in 2005 by Geoscience BC. The Property was staked based on the results of a stream sediment sample (83D053003) collected during this survey. This sample demonstrated 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. Field work in 2012 consisted of silt and moss mat sampling of the discovery creek. Five conventional silt and 2 moss mat samples were collected from five sample sites. The moss mats were taken to determine if there was any advantage to the sample media. Results demonstrated no advantage or disadvantage to the sample medium. 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 (Vanderwart, 2012). Highlights of the silt sampling included total REE concentrations of 0.72% and 0.36%. The ratio of the light REE compared to heavy REE is approximately 4:1.

4.0 EXPLORATION Field work was undertaken between September 28 and 30, 2013. Exploration consisted of collection of one stream sediment sample and 20 soil samples. The objectives were to test the silt geochemistry from the next drainage up Dave Henry Creek from the drainage sampled the previous year. Soil sampling was undertaken to follow up on the promising silt samples located in 2012.

4.1 SILT SAMPLING One sample (34118) was collected from the creek draining the area northeast of the creek sampled in 2012. Silt material was collected from a trap site along the creek bank. The material collected appeared quite sandy so a large sample (~2 kg) was collected to ensure enough silt would be available for analysis. The sample location was GPS-located with a hand-held Garmin eTrex unit. Flagging tape labeled with the sample number was affixed to a nearby tree. Sample location and results are shown in Figure 4.

34118 Silt 364678 5851502 The silt sample was placed in a labeled polyethylene sample bag and sealed with a plastic tie lock. The sample was 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 certificate of analysis for the silt sample is presented in Appendix II. ALS quality control consisted of routine use of standards, blanks and duplicates.

4.1.1 Results The silt sample collected did not return anomalous concentrations of REE’s, at least in the same order as those from the sampled creek drainage to the south. This drainage sources a fairly large area and additional sampling should be considered at higher elevation, particularly in the southern and western areas of the drainage basin.

4.2 SOIL SAMPLING A total of 20 soil samples were collected along two lines (un-cut) parallel to the northeast side of the main creek, starting approximately 35 metres downstream of 2012 silt sample 34112, to approximately 40 metres upstream of silt sample 34113 (Figures 4, 5). The “lower” line was placed approximately 25 metres upslope from the watercourse. The “upper” line was placed 25 metres upslope from the lower line. Sample stations were approximately 25 metres apart using a tight-chain. Stations were marked with labeled flagging. A very deep organic layer and poorly developed soil profile was prevalent at all sites. Small pits were dug with a Geotul to a depth ranging from 15 to 30 cm. Soil material was collected and placed into pre-labeled Kraft tin-tie soil sample bags and sealed. Samples were delivered to ALS for sample preparation and analysis. Sample analysis was the same method as described for the silt sample. The certificate of analysis for the soil samples is presented in Appendix II. A complete list of the soil samples, UTM locations and selected analytical results are presented in Appendix III. Soil geochemistry plan maps of the selected REE elements are presented on Figures 5 through 9. Figures 5 and 6 present selected elements of the light REE’s and Figures 7 to 9 present selected elements of the heavy REE’s.

4.2.1 Results Results of analysis of the soil samples returned two anomalous samples in REE’s, samples 105 and 113, the latter which consistently returned the highest values of all REE’s analyzed. REE concentrations in sample 105 are weakly anomalous as compared to the remaining samples. These two samples, suggest a possible narrow zone, or possibly a downslope dispersion, of REE concentration in soil parallel to (or associated with) the small intermittent creeks and/or avalanche tracks on the northeast side of the main creek. Extending this zone to the main creek connects immediately above the site of the highest REE-in-silt sample, 34112 (see Figures 5 to 9).

5.0 CONCLUSIONS AND RECOMMENDATIONS Two of the 20 soil samples collected demonstrate elevated REE values. Sample 113 collected from the upper line returned the most anomalous values, while sample 105 on the lower line returned lower values, but still anomalous as compared to the remainder of the soil samples. Sample 113 may exhibit higher concentrations as the soil profile is slightly better developed in this area as the slope is gentler as compared to the lower soil line where the slope steepens toward to the creek. There is also evidence of slope instability in the area adjacent to the creek which would also lead to poor soil development. The source of the REE-in-silt anomaly identified in 2012 has yet to be adequately identified and explained. Future work should include rock sampling to identify possible REE-bearing lithologies. No outcrop has yet been identified during either field visits. Upslope of soil sample 113, in and around the small watercourse, would be an area to examine for potential outcrop. Rock sampling on the upper ridgelines would likely provide the best location of outcrop. Additional soil sampling above and bracketing sample 113 should also be considered. Respectfully Submitted,

Theodore (Ted) W. F. VanderWart, B.Sc. January 7, 2014.

SAMPLE PREPARATION AND ANALYTICAL METHODS

Sample preparation package

prep- 41Standard preparation: dry Sample and dry- Sieve to –180 micron

Revision 02.01 | Feb 22, 2010 www.alsglobal.com

sample preparation is the most critical step in the entire laboratory operation. The purpose of preparation is to produce a homogeneous analytical sub-sample that is fully representative of the material submitted to the laboratory.

an entire sample is dried and then dry-sieved using a 180 micron (Tyler 80 mesh) screen. The plus fraction is retained unless disposal is requested. This method is appropriate for soil or sediment samples up to 1 kg in weight.

Sample preparation Flowchart package –prep- 41

* if samples air-dry overnight, no charge to client. if samples are excessively wet, the sample should be dried to a maximum of 120°c. (DRY-21)

# The plus fraction is the material remaining on the screen. The minus fraction is the material passing through the screen.

† The plus fraction is retained unless disposal is requested.

analytical methodInductively Coupled Plasma – Atomic emission spectroscopy (icP - aes)

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
