1. SURVEY DETAILS

1.1 PROJECT NAME

This project is known as the Beemer Property.

1.2 CLIENT

ASHLEY GOLD MINES LIMITED

14579 Government Rd. Larder Lake, Ontario P0K1L0

1.3 LOCATION

The Beemer Property is located approximately 45km south of Timmins, Ontario. The magnetic trav-erse area is located in Beemer Township and covers mining claim 4202436 and 4202435, within the Porcupine Mining Division.

1.4 ACCESS

Access to the property was attained with a 4x4 truck via highway 566 west from Matachewan. From here a forestry road was followed for an additional 75km. The crew then stayed at the Argyle Lake Lodge and commuted from there.

1.5 SURVEY GRID

The traversed lines were established using a GPS in conjunction with the execution of the survey. The GPS operator would establish sample locations while remaining approximately 25m in front of the magnetometer operator. GPS waypoints and magnetic samples were taken every 25m along these controlled traverses. The GPS used was a Garmin 76 with an external antenna for added ac-curacy.

2.2 PERSONNEL

Rod Milligan of Kirkland Lake conducted all the magnetic data collection and Correy Rozell was also responsible for the GPS control and GPS waypoint collection.

2.3 SURVEY SPECIFICATIONS

The survey was conducted with a GSM-19 v7 Overhauser magnetometer/VLF with a second GSM-19 magnetometer for a base station mode for diurnal correction.

A total of 17.4 line kilometers of no grid magnetometer/VLF EM survey was read over the Beemer Property between August 6th and 7th, 2008. This consisted of 696 magnetometer samples taken.

2.4 ACCURACY AND REPEATABILITY

Generally baseline repeatability was within 8nT in low gradient areas. This error was due to the small errors (<5m) generated by the GPS location.

3. OVERVIEW OF SURVEY RESULTS

3.1 SUMMARY INTERPRETATION

The east portion of the survey exhibits some intense magnetic variations. These intense variations appear to be isolated by a VLF EM axis striking at 25 degrees from 800N and 1500E. This VLF EM axis most likely represents a structural feature which constrains the magnetically intense east portion. This most likely represents a mafic or ultramafic unit.

The central region of the survey area appears more magnetically stable with a few magnetically high regions, which most likely represents a similar ultramafic region. Through this region appears to strong VLF EM avis bearing at approximately 300 degrees. These bedrock anomalies most likely represent a strong shearing or conductive structure. This axis should be further investigated through geophysics and prospecting.

THEORETICAL BASIS AND SURVEY PROCEDURES

TOTAL FIELD MAGNETIC SURVEY

Base station corrected Total Field Magnetic surveying is conducted using at least two synchronized magnetometers of identical type. One magnetometer unit is set in a fixed position in a region of stable geomag-netic gradient, and away from possible cultural effects (i.e. moving vehicles) to monitor and correct for daily diur-nal drift. This magnetometer, given the term ‘base station’, stores the time, date and total field measurement at fixed time intervals over the survey day. The second, remote mobile unit stores the coordinates, time, date, and the total field measurements simultaneously. The procedure consists of taking total magnetic measurements of the Earth’s field at stations, along individual profiles, including Tie and Base lines. A 2 meter staff is used to mount the sensor, in order to optimally minimize localized near-surface geologic noise. At the end of a survey day, the mobile and base-station units are linked, via RS-232 ports, for diurnal drift and other magnetic activity (ionospheric and sferic) corrections using internal software.

For the gradiometer application, two identical sensors are mounted vertically at the ends of a rigid fiberglass tube. The centers of the coils are spaced a fixed distance apart (0.5 to 1.0m). The two coils are then read simul-taneously, which alleviates the need to correct the gradient readings for diurnal variations, to measure the gradi-ent of the total magnetic field.

VLF Electromagnetic

The frequency domain VLF electromagnetic survey is designed to measure both the vertical and horizontal in-phase (IP) and Quadrature (OP) components of the anomalous field from electrically conductive zones. The sources for VLF EM surveys are several powerful radio transmitters located around the world which generate EM radiation in the low frequency band of 15-25kHZ. The signals created by these long-range communications and navigational systems may be used for surveying up to several thousand kilometres away from the transmit-ter. The quality of the incoming VLF signal can be monitored using the field strength. A field strength above 5pT will produce excellent quality results. Anything lower indicates a weak signal strength, and possibly lower data quality. A very low signal strength (<1pT) may indicate the radio station is down.

The EM field is planar and horizontal at large distances from the EM source. The two components, electric (E) and magnetic (H), created by the source field are orthogonal to each other. E lies in a vertical plane while H lies at right angles to the direction of propagation in a horizontal plane. In order to ensure good coupling, the strike of possible conductors should lie in the direction of the transmitter to allow the H vector to pass through the anomaly, in turn, creating a secondary EM field.

The VLF EM receiver has two orthogonal aerials which are tuned to the frequency of the transmitting station. The direction of the source station is locate by rotating the sensor around a vertical axis until a null position is found. The VLF EM survey procedure consists of taking measurements at stations along each line on the grid. The receiver is rotated about a horizontal axis, right angles to the traverse and the tilt recorded at the null posi-tion.

Taking Advantage of a “Quirk” of Physics

Overhauser effect magnetometers are essentially proton precession devices except that they produce an order-of magnitude greater sensitivity. These "supercharged" quantum magnetometers also deliver high absolute accu-racy, rapid cycling (up to 5 readings / second), and exceptionally low power consumption.

The Overhauser effect occurs when a special liquid (with unpaired electrons) is combined with hydrogen atoms and then exposed to secondary polarization from a radio frequency (RF) magnetic field. The unpaired electrons transfer their stronger polarization to hydrogen atoms, thereby generating a strong precession signal-- that is ideal for very high-sensitivity total field measurement. In comparison with proton precession methods, RF signal generation also keeps power consumption to an absolute minimum and reduces noise (i.e. generating RF fre-quencies are well out of the bandwidth of the precession signal).

In addition, polarization and signal measurement can occur simultaneously - which enables faster, sequential measurements. This, in turn, facilitates advanced statistical averaging over the sampling period and/or increased cycling rates (i.e. sampling speeds).

The unique Overhauser unit blends physics, data quality, operational efficiency, system design and options into an instrumentation package that ... exceeds proton precession and matches costlier optically pumped cesium capabilities.
