4 Claim and Data Gathering Overview The Ronin Placer Claims encompass the majority of the surface and suspected subsurface drainage systems on the benches above Rock Creek centered roughly on the historic Denver Bar. This area, especially the current path of Rock Creek, has been explored and mined for placer gold for more than a century. In addition, Regional GeoChemical Surveys available online from BCGS Geology also indicated high gold values from soil samples on Rock Creek and several of the streams in the surrounding area. Other factors that contributed to the selection of this area for exploration and development included proximity to roads and power and a lack of conflicting interests. The majority of the claim is not privately owned, although legacy placer claims and mineral claims overlap in some areas especially towards the existing channel of Rock Creek and around the historical War Eagle and Dayton mines. The specific claims covered by this scope of work are owned and operated by Warren Tessari representing Ronin Exploration Ltd. The tenure numbers for the overall group of adjacent claims are and , and they are outlined in red on the index map in this report. The specific claim upon which this investigation was performed was This specific claim is also identified on Plan Map A in this report. Accesses to the claims are via Fish Lake Road on the east side and Mount Baldy Road on the west side of Rock (or Jolly) Creek, approximately 60km east of Osoyoos on Hiway 3. There is a substantial system of non-maintained forestry and mining trails throughout the claims. Access to the area where the radar work was performed in this study is approximately 5.4 km north of Hiway 3 on Fish Lake road. Approximately 4 km of 50 MHz radar data was gathered on July These paths were pre-selected to use the most apparently traversable ground based on readily-available satellite data and pre-data gathering orientation and line layout. Several of the lines go in and out of the claim boundary as larger forestry roads were followed. Ronin July 2011 Radar Report Page 4

5 Approximately 4.5 km of 50 MHz radar data was gathered on July These paths were laid out to be followed as best as possible disregarding terrain where feasible to fill in the blanks from the previous data set. Overall approximately 8.5km of radar data was gathered, in addition to lines gathered during first pass prospecting in October 2010 along Fish Lake Road. The purpose of the Ground-penetrating Radar (GPR) survey was to identify target areas for drilling and gathering of samples from depth to be performed at a later date. Apparent subsurface channels, both current and historical, were noted in the data and transferred to topographic field maps quantitatively using non-differential GPS coordinates attached to the data.

6 Radar Equipment, Methods, and Ground Conditions 50 MHz radar data was gathered by towing the radar transducer across targeted areas by foot. Field markers were placed to correspond with radar line starts and stops, and GPS tracks were gathered with the coordinates embedded in the radar data for future reference and evaluation. For this study the 50MHz Rough Terrain Antenna made by MALÅ Geoscience was used. The transmitter and receiver are both contained in a single, snake-like unit. The system operates at 50MHz with trace spacing based on elapsed time. The X3M/CU-II control module was connected to a Garmin GPS Map 76C to provide continual satellite positioning information for correlation to the radar data. All depth measurements were based on an estimated radar velocity for the expected soil type. For the purposes of this survey, all depths were relative rather than absolute and intended to be verified and corrected in the future through other forms of testing such as drilling. Specifically, depth was indicated by nanoseconds corresponding to the signal travel time to and from the radar unit. Based on the estimated soil conditions, a depth approximation in meters was also provided by the radar unit. Depth was limited overall due to extremely high ground water. The spring and early summer of 2011 had been abnormally wet and subsurface and surface water was apparent in many places. There appears to be an abundance of overlying glacial till in all areas, which is typically excellent material for radar penetration, however water saturation made depth estimates difficult. The topography, as shown on the index map, is variable and slopes overall towards the stream bed of Rock Creek and its tributaries. Both surface evidence and subsurface data indications show mixedsize material ranging from sand, to cobbles to boulders, and varying from very well to very poorly sorted throughout the area. Although penetration was limited overall, indications of subsurface channels were noted in the data. As well, areas of greatest saturation were mapped as supporting evidence for locating subsurface channels. Additional radar data should be gathered later in the season when saturation has diminished somewhat, perhaps during winter when snow is covering deadfall, and when more target areas have been identified based on historical research, soil and silt sampling, etc. Ronin July 2011 Radar Report Page 6

7 Data and Diagrams Figure 2: Sample Radar Data RADAR LINE 77 HYPERBOLAS HORIZONS HORIZONS APPARENT WATER SATURATION This figure is an example of 50MHz radar data gathered during the survey. The salient features include subsurface horizons or layers, apparent water saturation, and hyperbolas indicating features such as boulders or tree roots. The depth in the data is given in nanoseconds, which is the most accurate representation of signal return. Any depth estimates are based on an estimated velocity and are intended to be verified during further testing. Distances along the ground were not taken from legend across the bottom of the data. Real-time GPS tags were employed instead and transferred as waypoints to Garmin MapSource and Google Earth Pro. During to the alluvial drilling/sampling program that will occur based the radar data gathering and analysis, the signatures will be confirmed where possible. Features such as water saturation, larger cobbles and boulders, and reflective layers such as iron/magnetite from old flow channels have corresponded very closely to the interpreted radar data in previous studies in the area. Lines of radar data were gathered for the overall area and in each individual proposed hole location for the placer test drilling program. Based on the data, the proposed hole sites will be adjusted to provide sampling points corresponding to likely subsurface channels. Ronin July 2011 Radar Report Page 7

9 July 7 and 12 Ground-penetrating Radar Survey Results The following results are taken directly from the data files captured by the MALÅ X3M/CU-II control module connected to the Garmin GPS Map 76C. The "Depth" and "Noted Signatures/Indications" columns were added by the radar technician for analysis, and specify the approximate depth to and description of the significant or typical apparent feature described. Lines 79 and 80 ran mostly parallel to the suspected subsurface channels, and the rest of the lines ran roughly perpendicular. Line 80 turns and crosses the suspected main channel, and this shows clearly in the data in that area. In occasional lines, the saturation was consistent enough that comments are made about the line overall, but no other signatures were noted with sufficient distinctive features to mention in this report. In those instances, time and positional data is indicated as "n/a" due to the lack of specific subsurface indications despite careful analysis. The positional data is given in decimal degrees because that is the format stored and exported by the MALÅ X3M/CU-II control module. Ronin July 2011 Radar Report Page 9

15 Appendix A: Radar Data The individual lines of radar data are included below for reference. Each is included in its entire length, but divided where necessary to fit the page. Due to the resolution of the 50 MHz system and the scope of the investigation, the scale as shown should be more than sufficient for a qualified individual to note the pertinent features. There is no Line 76 because it was a start/stop without data. See Figure 3: Plan Map A for the relative positions of each line. RADAR LINE 71 RADAR LINE 72 Ronin July 2011 Radar Report Page 15
