SUMMARY

Thirty-four audio-magnetotelluric (AMT) measurements were collected in Morgan Township, Sudbury, Ontario at an average spacing of 300m along 6 north-south oriented lines, spaced 300m apart (~9 line kilometers). AMT data in the frequency range 5.0-20,000 Hz, were acquired between September 30 and October 2, 2000, using three 5-channel Metronix 24 bit ADU-06 acquisition systems. One system was a fixed reference station in a culturally quiet location, while the other system was used within the prospect area. Each AMT measurement consisted of a perpendicular pair of 50m dipoles; two orthogonal magnetic field sensors, and one vertical magnetic field sensor. Robust processing resulted in generally good data quality within the survey area. Data were edited, rotated using Swift decomposition (principle axis), and static shifted. The results are shown as a series of pseudo-sections of apparent resistivity and phase for each of the TE and TM modes, in frequency-distance space.


1. INTRODUCTIONThis report describes acquisition and processing procedures of an audio-frequency magnetotelluric (AMT) survey conducted in Cascaden Township near the northwestern corner of the Sudbury Basin, on behalf of Wallbridge Mining Company Ltd.. A total of 34 AMT stations were occupied along 6 north-south oriented profiles. Station coordinates are listed in Appendix HI.

1.1 Survey design

Figure l: Profile locations.Coordinates are in meters on the UTM grid

The survey was carried out by Geosystem Canada Inc. using two 24-bit ADU-06 systems manufactured by Metronix GmbH of Braunschweig, Germany. Magnetic sensors were the BF-6 induction coils produced by Electro-Magnetic Instruments Inc. (EMI) of El Cerrito, California. Appendix II contains a description of the personnel and equipment used for the survey, along with a description of the data formats.Layout followed the normal MT axis convention, that is, a right-handed system with z positive downwards. Dipole lengths of 50 meters and a fixed acquisition azimuth of geographic north was used throughout the survey. Access to the grid was by 4WD vehicle as far as possible, and then on foot. Due to the low system weight, the operator and 2 helpers were able to pack all of the necessary gear without difficulty.

1.2 Data AcquisitionThe time series data were acquired in 2 sample bands. The highest sample rate used was 40960 Hz for a duration of 7 seconds. A 4069 Hz sample band was recorded for 6 minutes. The 4096 Hz sample band was decimated to a sample rate of 256 Hz to compute the low frequency data.


2. DATA PROCESSING AND EDITING

2.1 Processing overviewThe basic steps required to transform field time-series to usable data are as follows:

1. Automatic selection of coherent data segments (low noise) by comparison of the electric and magnetic fields in each band (40960, 4096, and 256 Hz);

2. Robust processing of the 300 most coherent data segments in each sample band;3. Merging of individual bands (3) to form a complete sounding curve;4. Checking of calculated curves for geophysical plausibility.

Data were archived on CD ROM on a daily basis after the time series was transferred from the field computers to the processing computer. Time series were viewed with the Metronix visualization program QuickLook. Automatic coherency selection and robust processing were carried out using routines developed by Jim Larsen (Larsen and others, 1996). Data analysis, interpretation, and presentation were completed with Geosystem's interpretation software, WinGLink.

2.2 Robust processingRobust processing techniques were employed to improve data quality and reduce the effects of noise bias. The method of Larsen and others (1996) was used to estimate smooth magnetotelluric transfer functions (i.e. impedances) relating the electric and magnetic field data.Data segments were automatically selected on the basis of electric and magnetic field coherency, and used as input to the robust processing algorithm. The magnetic and electric fields are used in an iterative re-weighted method to determine the impedance tensor. During the iterations, the electric fields are corrected in both the frequency and time domains, utilizing a smooth MT transfer function to estimate the electric field data from the magnetic fields. The total time required to robust process a single sounding was approximately 10 minutes.The program outputs data at 8 equi-spaced frequencies per decade (e.g. 10, 15, 22, 32, 42, 48, 62, and 82 Hz). All of the soundings were processed using the robust algorithm.


3. DATA PRESENTATION

3.1 Data description and dimensionalityThe AMT responses are primarily two-dimensional over the acquired frequency band. Data were rotated to principal axis (Swift angle), with an average strike direction of 3 O0, decomposing the data into responses parallel and perpendicular to strike (the TE and TM modes respectively). At most stations, piow is aligned along the strike direction and is therefore the TE mode. An example of this is shown in figure 2.

Figure 2: Sounding l lE04n. located in the south-central part of the grid The blue apparent resistivity curve is identified as the TM mode; the overall curve shapes at all of the sites in this prospect are m general similar.

3.2 Static shiftStatic shift, i.e. the frequency-independent shift of apparent resistivity curves, is caused by near-surface conductive inhomogeneities, which distort the local electric fields (Groom and Bailey, 1989). Without external data, there is no unique way of resolving this effect. Impedance phase, which is proportional to the slope of the apparent resistivity curves, is nearly independent of static shift. Phase pseudo-sections were therefore used as a guide to static- shifting of the apparent resistivity curves. In general, piow was shifted to coincide with

the high-frequency end of the curves.

5. 3 Pseudo-sectionsPseudo-sections (in frequency/distance space) of observed apparent resistivity and phase are plotted for all lines used for inversion in Appendix I.

Appendix II-3: Data formats

Original field data were archived in time-series files in a mixed binary format as written by the Metronix acquisition program GMS183b. All times series data is stored in a directory corresponding to the site name within a directory designated by the date of acquisition. Individual files within the directory follow the following convention.

ssscrrtb.ATS where:

sss = ADU06 serial numberc = ADU06 channel number (as l.. 11=8)rr = Run numbert = channel type ^Ex, b=Ey, x^Hx, j^Hy, zFHz)b = Sample rate (3=40960, b=4096, 0=64, f^2048 or 512 Hz)

EDI files:EEeNN.EDI, defines an EDI file obtained by robust processing.

Where: EE - Station grid eastinging in units of 100m. NN = Station grid northing in units of 100m.

Data were normally archived in the following formats:1. SEG-Electromagnetic Data Interchange (EDI) format containing all cross-powers;2. Binary files in Metronix GMS183b format containing acquisition information and

time-series.The SEG MT/EMAP Data Interchange Standard is described in Wight, 1988. Since this is an extremely lengthy standard (91 pages), the reader is referred to that document for details.

1. Introduction

The Wallbridge Mining Company Limited believes the footwall of the Sudbury Impact Complex (SIC) is an excellent location to explore for Sudbury type mineral deposits. They acquired property in Cascaden Township, Sudbury Mining Division, to prospect for this type of mineralization. The are has been the subject of only limited prospecting in the past with limited encouraging results. Using an impact model, Wallbridge has commenced prospecting. As part of that prospecting Wallbridge employed AMT to investigate deep mineralization.

2. Location and Access

The site is situate west of Windy Lake in the central portion of Cascaden Township. It may be accessed by traveling north from Sudbury on Hwy. #144 to Windy Lake Park. Take the first left (south) turn past Windy Lake Park after crossing the railway tracks. From there travel 2 kilometers in a southerly direction to the grid on claim S-1229457. The road may be traveled by car.

3. Property

The property explored consists of 4 unpatented mining claims, 39 units. All claims are held lOO'M* by Wallbridge Mining Company Limited.

5. Anomalies

There were no significant anomalies detected in the survey. See the GEOSYSTEM report for details.

6. Recommendations

Though the AMT failed to detect any promising anomalies, the area should still be considered for mapping and possible for IP. to detect near surface disseminated mineralization possibly hosting platinum group elements. See the GEOSYSTEM report for details.
