1. SUMMARY

A VTEM airborne electromagnetic and magnetic survey was carried out for Shoreham Resources Ltd.

(now Guyana Frontier Mining Corp.) by Geotech Airborne Ltd. (Geotech) in April 2010 over the

Twinpeaka area, located in northwest Ontario, Canada.

Condor Consulting Inc. (Condor) was commissioned to carry out comprehensive processing,

analysis and interpretation of the EM and magnetic data from the VTEM surveys.

An interpretation report for this survey was delivered in October 2011 (Irvine 2011a).

Additional interpretation including Maxwell EM modeling and Model Vision magnetic modeling of

some of the target zones was carried out in November 2011 (Irvine 2011b).

In April 2012, the client requested that the following additional work be carried out:

Maxwell modeling on five extra Target Zones (TZ 4, 10, 12, 26 and 37).

Proposed drill holes be designed to test the best portions of these TZ.

NOTE: The present report incorporates this additional work and should be read in

conjunction with the original report.



2. INTRODUCTION

Between March 31 - April 12, 2010 Geotech carried out a VTEM airborne geophysical survey for

Shoreham Resources Ltd. (now Guyana Frontier Mining Corp.) (Guyana) over the Twinpeaka area,

located in northwest Ontario, Canada.

The location is shown in Figure 1.

Figure 1: Location of Twinpeaka VTEM survey area.

The flight path for this survey is shown in Figure 2 and covered two claim blocks - Setting Net Lake in

the west and Twinpeaka in the east, both owned by Guyana. The nominal flight line spacing was 100

m over Setting Net Lake and 150 m over Twinpeaka. The total line km flown was 540.7 km. Both

dBdT and B-Field data were collected and X and Z components were acquired.

The Geotech Logistics Report (Acorn et al. 2010) provides specific details of the VTEM

instrumentation and survey (included on the DVD, Appendix C).

3. EM INTERPRETATION

All the picked conductors are shown overlain on an image of the DEM, also showing the lakes and

rivers, in Figure 3. The conductors picked as surficial correlate with topographic lows and in many

cases with lakes, which likely have conductive lake bottom sediments. Some of the “edge of surfi-

cial conductor” picks lie within a large lake and likely reflect a deepening of the lake bottom and

additional thickness of sediments.

The surficial and edge of surficial conductors are not considered to have economic significance

and therefore have been omitted from subsequent maps.

The bedrock conductors are shown in Figure 4 superimposed on the geology.

The bedrock conductors and defined TZ are shown in Figures 5.

The primary characteristics of the TZ are listed in Table 3-1. Forty one TZ have been defined within

the Twinpeaka survey. Of these 11 are rated as Priority 1 (high priority), 12 as Priority 2 and 18 as

Priority 3 (low priority). Twenty eight TZ lie within the Setting Net Lake claim block and 13 lie within

the Twinpeaka claim block.

4. MAXWELL MODELING

Maxwell is an EM modeling program developed by EMIT (Electro Magnetic Imaging Technology) of

Perth Australia. Maxwell is designed for the analysis of ground, borehole and airborne survey. A

brief description of Maxwell is provided in Appendix A. Modeling in Maxwell uses either “thin” or

“thick” plates. Thin plates are defined as inductively thin and are modeled using a “sheet” consist-

ing of many current filaments aligned within the plane of the sheet. Thick plates are modeled as six

thin plates, corresponding to the two sides, the two ends and the top and bottom of the thick plate.

Normally the top and bottom sheets are kept horizontal, even when the dip is changed. This simple

representation of thick plates speeds up calculations significantly and makes inversions feasible.

Note that Maxwell displays the X, Y and Z coordinates of the center-top of the plate. The latter may

coincide with the flight lines, but in many cases the plate is not symmetric with respect to the flight

lines and so the X and Y coordinates lie off the flight line. This needs to be kept in mind when de-

signing drill holes to intersect the plate. Preferably, drill holes should be designed using 3D visuali-

zation software which displays the 3D DXF model of the Maxwell plate. The Maxwell software in-

cludes this capability.

An explanatory diagram showing the model plate parameters is shown in Appendix A. The client specified that Maxwell modeling be performed on anomalies within five TZ, viz. TZ 4, 10,

12, 26 and 37.

The locations of these TZ are shown in Figure 6.

Within each TZ, modeling was performed on lines where the anomalies has sufficient amplitude

and simplicity to generate a robust inversion solution. Some lines were omitted because the

anomalies were complex or had overlapping conductors. A total of 15 lines were modeled.



Figure 6: TZ for which Maxwell modeling has been performed (on RTP image).



Table 4-1 lists the flight lines for which Maxwell modeling was performed.

Table 4-1: Maxwell Modeling Lines.

TZ Lines

4 1000, 1010, 1020 10 1110, 1120, 1130 12 1180, 1190, 1200 26 1410, 1420, 1430 37 1580, 1590, 1600

When modeling each line, a plate strike length appropriate to the total length of the conductor was

used. However, these plates overlap and when plotted in 2D maps or 3D views become “messy”

and difficult to differentiate. Consequently, after modeling these plates have been truncated to

have a strike length approximately equivalent to the line spacing and centered on the flight line, so

that they do not overlap when plotted. The plate location is still appropriate for designing drill holes

to test the conductors.

Figures 7a and 7b show the truncated plates, projected to surface.

The 3D dxf files for all plate models are included on the DVD (Appendix C). These can be input

into GIS software. Also included are the Maxwell project files (in case additional modeling is re-

quired) and screen saves of the modeling for all 15 lines.

5. PROPOSED DRILL HOLES

At the request of the client, drill holes were designed to test the conductors defined in TZ 4, 10, 12,

26 and 37. In all of these TZ conductors were observed on multiple flight lines. The drill hole for

each TZ has been sited close to the VTEM flight line where the observed conductor response is

maximum and/or the profiles show a well-defined anomaly which has been robustly modeled with a

plate conductor using Maxwell. The drill holes have been located to test these plate model con-

ductors.

A single drill hole has been proposed for most of the TZ.

Table 5-1 lists the proposed holes. Figures 8a and 8b show the locations of the holes.

7. CONCLUSIONS AND RECOMMENDATIONS

Maxwell modeling has been carried out on 5 additional TZ to assist in defining the targets in prepa-

ration for drill targeting (viz. TZ 4, 10, 12, 26 and 37). Proposed drill holes were designed to test

each conductor. These proposed holes are located to optimally test the plate conductors defined

by the Maxwell modeling.

The proposed holes and the Maxwell plate conductors have been compiled in 3D views, which can

be viewed using Encom PA free software, to better facilitate the spatial relationships.
