1. SURVEY DETAILS

1.1 PROJECT NAME This project is known as the Ministic Property.

1.2 CLIENT Wallbridge Mining Company Limited 129 Fielding Road Lively, Ontario P3Y 1L7

1.3 LOCATION The Ministic Property is located approximately 30km west of Chelmsford, Ontario. The grid area is located in Ermatinger Township and covers a portion of mining claims 1244387, 1244719, 4207192 and 4207193, within the Sudbury Mining Divi-sion.

Figure 1: Location of Ministic Property



1.4 ACCESS Access to the property was via a 4x4 pickup truck along with a snowmachine. The Windy Lake Road is travelled west from highway 144 at Windy Lake. Near kilometer 8, the Chicago Mine Road extends southward and is travelled 2.5 km to the Ministic Lake boat launch. At this point, a snowmachine is used to access the final 5km across the ice to the survey area.

1.5 SURVEY GRID The grid was established prior to survey execution and consisted of 11.75 kilometers of grid lines. The survey lines were spaced at 150-250 meters and stations were picketed at 25m intervals with the baseline running at 140°N for a total of 1650 me-ters.

2.2 PERSONNEL

Jason Ploeger of Larder Lake, Ontario, operated the MaxMin receiver and Bruce La-valley of Britt, Ontario, operated the MaxMin transmitter.

2.3 SURVEY SPECIFICATIONS The survey was conducted with an APEX PARAMETRICS MAXMIN II. Frequencies 222Hz, 444Hz, 888Hz, 1777Hz and 3555Hz were used with a 200m coil separation. A Suunto PM-5 clinometer was used to measure slopes between picketed stations. These slopes were averaged over 50m to determine the correct tilt readings. A total of 2.5 line kilometers of MaxMin was read on February 11th, 2014. This con-sisted of 168 samples taken in 222Hz, 444Hz, 888Hz, 1777Hz and 3555Hz at a 12.5m sample interval.



3. OVERVIEW OF SURVEY RESULTS

3.1 SUMMARY INTERPRETATION Within the area, it was noted that there was a low frequency noise. This was more apparent in frequency 222Hz and occasionally crept into frequency 444Hz. When this noise was noted, many repeats were taken until two back to back readings re-peated themselves. Generally, the higher frequencies were stable once the initial reading was taken. The topography was difficult over the grid. This includes steep inclines and sidehills throughout the grid. Care was taken to keep the coil and receiver coaxial at a properly corrected distance between transmitter and receiver. This being said there may be some minor topographical variances within the dataset. One variance will most likely occur when the cable was straddling 900W due to a cliff. The cable length corrections required was slightly longer than the extra cable incorporated into the cable. This meant that for the 200 meters the Rx Tx separation was approxi-mately 195m. No strong obvious responses or trends were noted in the data. Two in phase and one out phase responses may occur. The first in phase response is noted as an unconstrained shoulder response located at 950W on line 900N. This response correlates with the location of the cliff and may be a result of this. The second response appears as a stronger negative in phase measurement cen-tered near 600W on line 900N. This may indicate a deeper conductive zone; how-ever, no shoulders are apparent to enable characterization. The out phase response occurs on line 750N centered at 350W. This response also exhibits some in phase movement in the high frequencies. This anomaly should be treated with caution because of its location in the water. This may be a result of a shoal. This anomaly being stronger in the out phase response trends it more into the realm of being overburden in nature.

APPENDIX B

THEORETICAL BASIS AND SURVEY PROCEDURES

HLEM Electromagnetic The HLEM method involves the use of a pair of separated horizontal coils (Figure MMI). Most commonly, the surveys are conducted in the frequency domain. In this method, a sine wave of variable frequency is sent through one of the coils to create a time-varying vertical magnetic dipole source. The second coil is a receiver which detects both the primary signal from the transmitting coil and a secondary signal created by magnetic induction in a conductive target in the earth. The HLEM method requires that a sample of the transmitted signal be sent along a wire to the receiver where it is used to synchronize the phase of the receiver with the transmitter. This permits the receiver to remove the effect of the transmitter signal (primary field) and to split the remaining secondary field into two components. One phase with the primary field (in-phase component). The second component is the portion of the secondary field which lags the primary field by one quarter cycle (90’ - quadrature component). The ratio of the in-phase to quadrature components is used to determine the electrical conductance of a target.

MMI: HLEM source field



HLEM instruments remove the primary filed from the signal to leave only the sec-ondary field. By convention, a secondary field in the same direction as the primary field is recorded as positive while a secondary field in the opposite direction to the primary field is recorded as negative. HLEM data is commonly plotted as profiles with the reading plotted at the midpoint between the transmitter and receiver. The reason for this is that the response from a steeply dipping conductor, the most com-mon target of this method, is strongest when the two coils straddle the conductor.



APPENDIX C

APEX PARAMETRICS MAXMIN II

Specifications Advanced spheric and powerline interference rejection results in faster and more ac-curate surveys, particularly at the larger coil separations. The Maxmin Computer or MMC is offered for digital data processing, display, stor-age and transfer. The MMC displays and stores the inphase and quadrature read-ings, their standard deviations, and the corresponding apparent ground conductivity values. Rough terrain surveys are also simplified with the MMC. Data interpretation and presentation programs are available for layered earth para-metric soundings and discrete conductor surveys.

Subject: Review of Ministic Geophysics with particular emphasis on recent

EM surveys

The Wallbridge Ministic property has been covered with multiple generations

of geophysical surveys with particular emphasis on EM surveys to assist in the

location of conductive Ni-Cu-PGE sulphide mineralization.

EM surveys have included full or partial coverage with:

Inco

- AEM/Mag

Wallbridge

- Regional airborne Geotem/Mag

- airborne VTEM/Mag 2013

- Ground UTEM5 2013

- airborne HeliTEM/Mag 2014

- ground MaxMin 2014

Reviews of these surveys have indicated 2 untested conductivity targets - one

fairly well defined and one probable.

The location of these targets are shown in Figure 1

The EM data over the property is in general of good quality but there is

increasing power line noise in the AEM surveys towards the east side of the

property and local interference over and around Ministic Lake from cottages

and electrical lines (some underwater).

Ground EM surveys were targeted on areas of interest identified from the

AEM surveys and other data.

Targets

EMAK2014-1

This target area was first identified in the later time (LT) 2013 VTEM AEM

db/dt and B field data as shown in Figure 2 and was subsequently covered by

ground UTEM5, airborne Helitem, and Maxmin surveys. The UTEM5 survey

showed small scale anomalies in the same area in most time channels and

components in in-loop and out-loop data.

Figure 2 VTEM AEM B Field (top) and and dB/dt (bottom)

The target is also apparent the Helitem LT db/dt data but is not as clear in the

Helitem B field data due to high noise levels.

The ground Maxmin data targeted on this anomaly was overwhelmed by

topographic noise and natural EM noise in the in-phase component with the

noise exceeding the expected response from the target as interpreted from

other EM surveys.

The target was modeling in Maxwell for VTEM, UTEM (in and out loop) and

Maxmin in an effort to find a source body that fit all the data. Interpretations

for the VTEM and UTEM surveys are similar but not identical suggesting an

area of small complex veins with various orientations rather than a single

discrete conductive body.

The characteristic double peaked VTEM LT B field anomaly suggests a small

sub-vertical relatively shallow source but most models (by Dele and myself)

also suggested a deeper good quality sub-horizontal or wide source to explain

the broad positive AEM late-time plateau typical of a flat or flat topped

source. However these models with flat sources were clearly not compatible

with the UTEM in-loop data that, with its mainly vertical primary field, should

be quite sensitive to any flat source body. After considerable work with the

various data sets it appears that the most likely scenario that could explain all

the data is as follows:

- a very small relatively shallow sub-vertical plate at the anomaly location

above a similar but slightly larger, deeper, and possibly fatter plate as

shown in Figure 3.

- the signal from these small very conductive plates decays slowly

explaining the discrete LT db/dt and B field responses.

- Because the signal is close to noise levels the characteristic null value in

the center of the anomaly due to a vertical plate is wiped out by natural

noise in the dB/dt data and by noise plus filtering applied in processing

to get the B field data. Hence the overall LT response is aliased

(destructively filtered) into a broad background response.

Figure 3 VTEM Line 2370 - Maxwell Model 3 Two fat Vertical Plates

Due to the variety of responses in the different surveys it appears that this may

be an area of small complex veins with various orientations rather than a single

discrete conductive body. In previous drilling on small high conductance

targets like this on the NW Range we have intersected conductive/magnetic

magnetite but in this case there is no local mag high over the EM anomaly.

It is likely that this conductor extends along strike to the conductor interpreted

by Dele on VTEM line 2380 as shown in plan view in Figure 4 . It may also

extend further SE to the crossover in the UTEM Z component data on Line

500 N although there is no clear evidence of this in the Helitem data.

Figure 4 UTEM and VTEM B field data in plan and VTEM B field data from L2380 shown

in profile plus Plates interpreted from VTEM data by AK L2370 (in blue) and Dele L2380

(shown in black)

An Autocad .dxf file of the most likely VTEM L2370 model (2 sub-vertical

plates at different depths at the anomaly location) is attached. The modeled

plate are small but quite conductive and are of interest as they could represent

small conductive veins in a larger less conductive/disseminated mineralized

system like the Vale’s Capre project.

Due to the uncertainty surrounding the exact nature of the source it is

suggested that all possible models be reviewed with the exploration team to

design a drill follow up plan that maximizes the probability of success.

EMAK2014-2

This target (shown in Figure 4) has only been detected in the Helitem data on

line L10100 but is similar enough to the EMAK2014-1 signature to warrant

further consideration if the results from EMAK2014-1 are positive.
