The caims are cated 30 km east f Mathesn, and access is prvided by Highway 101, which cuts the suthern part f the caims. Caim detais are prvided bew and are shwn n Figure 1, which as shws the grid catin.

Csts f the prgram are prvided in Appendix 2. This reprt was prduced between December 20 and December 22, The bjective was t investigate MegaTEM cnductrs reveaed by the 2003 Discver Abitibi MegaTEM prgram. Previus Wrk Histrica wrk reating t gd mineraizatin dates back t 1900 and by the 1950's, additina effrts were directed twards discvery f asbests depsits. Michaud twnship was systematicay mapped by J. Sattery in 1946 (ODM Map ). The area f the prperty was shwn t be underain by mafic vcanic rcks, athugh verburden cver was extensive. The area suth and east f the MegaTEM cnductrs was the subject f a brief mapping prgram fr AMAX: in 1979 (Wiimasn, 1979). Basat and diabase utcrps were described, athugh mst f the prperty was cvered by thick verburden. Mag, VLF and HLEM surveys were cnducted n a arge grid by Gden Range Resurces in 1984 (Tittey, 1984). The grid encmpassed sme f the present prperty and the bjective f the prgram was t find gd depsits n spays f the Destr - Prcupine Faut system. Tw drihes were cmpeted n gd targets by Nranda in June, 1986 (AFRI 42A09SE0322). GR was cared n the present prperty and ended in a zne f sheared, carbnatized andesite with quartz-pyrite veins. 13 f 14 sampes returned backgrund vaues, with the ther sampe returning 0.2 g/t Au. Traces f sphaerite were nted in a quartz dirite intrusin. Anther mapping prgram was undertaken by Nranda n behaf f Gden Range Resurces (Dunbar, 1986) in Juy, The nrth imit f this mapping was -150 m suth f the MegaTEM cnductrs which are the fcus f the current prgram. Gabbr was described suth f the present prperty. Fur drihes were cmpeted by Gden Range Resurces in June f 1988 (AFRI 42A09SE0301). Tw f these (GRM-88-03, GRM-88-04) were n the suth end f the present prperty and bth intersected pyrite and pyrrhtite in graphitic intervas within mafic vcanic sequences. N basemetas were nted and n anmaus gd cncentratins were returned. The prperty was incuded in the Discver Abitibi MegaTEM prgram in Wrk Prgram Linecutting was cnducted by Services Expratin f Ruyn, Quebec, between Octber 12 and Octber 19, The grid catin is shwn in Figure 1. GPS readings were taken n the baseine after it was cut t psitin it prperty.

The magnetmer was a GSM-19 "Overhauser"-type mag and data was crrected fr drift with an autmatic recrding base statin. Descriptin and specificatins f the mag are prvided in Appendix 3. Psted data is shwn n Figure 2 and cured magnetics are shwn n Figure 3. Tta magnetic reief is abut 900 nt. A mag high ccurs n the mst eastern and western ines at abut 300 m nrth f the baseine. It is strngest n Line 0+OOE, where it is abut 300 nt abve backgrund. A grund TDEM survey was run n 7 ines by Quantech, f Timmins, Ontari between Nvember 23 and Nvember 25, Instrument specificatins, gistics reprt and a cmpete set f prfies are prvided in Appendix 4. Data is as presented as psted channe 10-"X" cmpnent n Figure 4, and as a series f cured maps f varius times n Figure 5. The strngest respnse is n Line 2E, where a brad and reativey weak "X" cmpnent respnse is present in the eary channes but decays rapidy and migrates nrthward away frm the p edge. This, and ack f a dear "Z" cmpnent crssver suggests the respnse is due t a brad zne f w cnductivity, pssiby reated t verburden which is suspected t be deep in this area.

The GSM-19 v6.0 Overhauser instrument is the tta fied magnetmeter t gradimeter f chice in tday's earth science envirnment representing a unique bend f physics, data quaity, peratina efficiency, system design and ptins that ceary differentiate it frm ther quantum magnetmeters. With data quaity exceeding standard prtn precessin and cmparabe t cstier pticay pumped cesium units, the GSM-19 is a standard (r emerging standard) in many fieds, incuding: Minera expratin (grund and airbrne base statin) u Envirnmenta and engineering Pipeine mapping Unexpded Ordnance Detectin Archegy Magnetic bservatry measurements Vcangy and earthquake predictin Taking Advantage f the Overhauser Effect Overhauser effect magnetmeters are essentiay prtn precessin devices - except that they prduce an rder-fmagnitude greater sensitivity. These "supercharged" quantum magnetmeters as deiver high absute accuracy, rapid cycing (up t 5 readings secnd), and exceptinay w pwer cnsumptin. The Overhauser effect ccurs when a specia iquid (with unpaired eectrns) is cmbined with hydrgen atms and then expsed t secndary parizatin frm a radi frequency (RF) magnetic fied. The unpaired eectrns transfer their strnger parizatin t hydrgen atms, thereby generating a strng precessin signa - that is idea fr very highsensitivity tta fied measurements. In cmparisn with prtn precessin methds, RF signa generatin as keeps pwer cnsumptin t an absute minimum and eiminates nise (i.e. generating RF frequencies are we ut f the bandwidth f the precessin signa). In additin, parizatin and signa measurement can ccur simutaneusy -- which enabes faster, sequentia measurements. This, in turn, faciitates advanced statistica averaging ver the samping perid and/r increased cycing rates (i.e. samping speeds). Other advantages are described in the sectin caed, "GEM's Cmmercia Overhauser System" that appears ater in this brchure.

16 Maximizing Yur Data Quaity withthegsm-19 Data quaity is a functin f five key parameters that GEM has taken int cnsideratin carefuy in the design f the GSM-19. These incude sensitivity, resutin, absute accuracy, samping rates and gradient terance. cnsidering factrs invved in determining the fied vaue and their accuracy, incuding the gyrmagnetic cnstant, maximum ffset f the time base frequency, etc. With an absute accuracy f +I- 0.1 nt, the GSM-19 is idea fr tta fied wrk and gradient measurements maintain the same high standard f quaity. Bth cnfiguratins are as speciay designed t minimize vera system nise s that yu can be sure that yur resuts truy refect the gegic signa that is f mst interest t yu. Samping rates are defined as the fastest speed at which the system can acquire data. This is a particuary imprtant parameter because high samping rates ensure accurate spatia resutin f anmaies and increase survey efficiency.

Sensitivity is a measure f the signa-tnise rati f the measuring device and refects bth the underying physics and eectrnic design. The physics f the Overhauser effect imprves sensitivity by an rder f magnitude ver cnventina prtn precessin devices. Eectrnic enhancements, such as high-precisin precessin frequency cunters (see the v6.0 - New Miestnes sectin) enhance sensitivity by 25^ ver previus versins. The resut is high quaity data with sensitivities f nt -J'Hz r better This sensitivity is virtuay the same as the sensitivity f cstier pticay-pumped cesium systems. GEM's Overhauser system has three "measurement mdes" r maximum samping rates - "Standard" (3 secnds i reading), "Waking" (0.5 secnds reading) and "Fast" (0.2 secnds / reading). These rates make the GSM-19 a versatie system fr a grund uses (incuding vehice-brne appicatins). Gradient terance is the abiity t btain reiabe measurements in the presence f extreme fied variatins. GSM-19 terance is maintained thrugh interna signa cunting agrithms, sensr design and Overhauser physics. Fr exampe, the Overhauser effect prduces high Tta Fied and Statinary Vertica Gradient shwing the gradient argey unaffected by diurna variatin. Absute accuracy is as shwn t be very high (0.2 nt/meter). ampitude, ng-duratin signas that faciitate measurement in high gradients.

17 Increasing Yur Operatina Efficiency Many rganizatins have standardized their magnetic gephysica acquisitin n the GSM-19 based n high perfrmance and peratr preference. This refects enhancements such as memry capacity; ight weight; GPS and navigatin; n warm-up time; n dead znes r heading errrs; and dumping and prcessing. Memry capacity cntrs the efficient daiy acquisitin f data, acquisitin f psitining resuts frm GPS. and the abiity t acquire high vumes f data t meet daiy survey bjectives. V6.0 upgrades have estabished the GSM-19 as the cmmercia standard fr memry with ver 262,000 readings (based n a basic cnfiguratin f 4 Mbytes f memry and a survey with time, crdinate, and fied vaues). Optina increments up t 32 Mbytes increase memry t ver 2 miin readings - making the GSM-19 an idea system fr acquisitin f data with integrated GPS readings (when required). Prtabiity characteristics (ruggedness, ight weight and pwer cnsumptin) are essentia fr peratr prductivity in bth nrma and extreme fied cnditins, GEM's Overhauser magnetmeter is estabished gbay as a rbust scientific instrument capabe f withstanding temperature, humidity and terrain extremes. It as has the reputatin as the ightest and west pwer system avaiabe -- refecting Overhauser effect and RF parizatin advantages. In cmparisn with prtn precessin and pticay pumped cesium systems, the GSM-19 system is the chice f peratrs as an easy-t-use and rbust system. GPS aridjiavicjain ptins are increasingy critica cnsideratins fr earth science prfessinas. GPS techngies are revutinizing data acquisitin enhancing prductivity, increasing spatia resutin, and prviding a new eve f data quaity fr infrmed decisin-making. As an innvative techngy deveper, GEM has made GPS a crnerstne f its magnetic R&D prgram. Rea time GPS and DGPS ptins are nw avaiabe in different survey resutins. Fr mre detais, see the GPS and DGPS sectin. GEM has as deveped a GPS Navigatin feature with rea-time crdinate transfrmatin t UTM, ca X-Y crdinate rtatins, autmatic endf-ine fag, guidance t the next ine, and survey "ane" guidance with crss-track dispay and audi indicatr. Other enhancements incude way pint pre-prgramming f up t 1000 pints. Prfessinas can nw define a cmpete survey n their PC and dwnad pints t the magnetmeter via RS-232 cnnectin - befre eaving fr the fied. The peratr then simpy perfrms the survey using the way pints as their survey guide. This capabiity decreases survey errrs, imprves efficiency, and ensures mre rapid survey cmpetin. Dumping and prcessing effectiveness is as a critica cnsideratin tday. Histricay, up t 60"7 f an peratr's "free" time can be spent n w-return tasks, such as data dumping. Data dumping times are nw significanty reduced thrugh GEM's impementatin f high-speed, digita data inks (up t 115 kbaud). This functinaity is faciitated thrugh a new RISC prcessr as we as GEM's prprietary GEMLinkW acquisitin t dispay sftware. This sftware serves as a bi-directina RS-232 termina. It as has integrated prcessing functinaity t streamine key prcessing steps, incuding diurna data reductin.

18 Adding Vaue thrugh Optins When evauating the GSM-19 as a sutin fr yur gephysica appicatin, we recmmend cnsidering the cmpete range f ptins ffered by GEM. These ptins can be added at time f rigina purchase r ater t expand capabiities as yur needs change r grw. GEM's apprach with ptins is t prvide yu with an expandabe set f buiding bcks: Gradimeter Waking Magnetmeter Gradimeter Fast Magnetmeter Gradimeter VLF (3 channe) GPS (buit-in r externa) GSM-19G Gradimeter Optin The GSM-19 gradimeter is a versatie. entry eve system that can be upgraded t a fu-featured "Waking" unit (mde GSM-19WG) in future. The GSM-19G cnfiguratin cmprises tw sensrs and a "Standard" cnse that reads data t a maximum f 1 reading every three secnds. An imprtant GEM design featu. its gradimeter sensrs measure the tw magnetic fieds cncurrenty t avid any tempra variatins that cud distrt gradimeter readings. Other features, such as singe-buttn data recrding, are incuded fr peratr ease-f-use. GSM-19W/WG "Waking- Magnetmeter Gradimeter Optin GEM Systems pineered the innvative "Waking" ptin that enabes the acquisitin f neary cntinuus data n survey ines. Since its intrductin, the GSM-19W GSM-19WG have becme ne f the mst ppuar magnetic instruments in the wrd. Simiar t an airbrne survey in principe, the system recrds data at discrete time intervas (up t 2 readings per secnd) as the instrument is carried ang the ine. At each survey picket (fiducia), the peratr tuches a designated key. The system autmaticay assigns a picket crdinate t the reading and ineary interpates the crdinates f a intervening readings (fwing survey cmpetin during pst-prcessing). A main benefit is that the high sampe density imprves definitin f gegic structures and ther targets (UXO, archegica reics, drums, etc.). It as increases survey efficiency because the peratr can recrd data amst cntinuusy. Anther prductivity feature is the instantaneus recrding f data at pickets. This is a basic difference between the "Waking" versin and the GSM-19 GSM-19G (the "Standard" mde versin which requires 3 secnds t btain a reading each time the measurement key is pressed). GSM-19F i FG "Fast" Magnetmeter/ Gradimeter Optin The "Fast" versin reads up t 5 readings per secnd. (Sensrs and cnse are the same as ther mdes.) This system is idea fr vehice-brne surveys, such as UXO, archegica r sme minera expratin appicatins, where very high prductivity is required. GSM-19 "Hands-Free" Backpack Optin ~he "Waking" Magnetmeter and Gradimeter can be cnfigured with an ptina backpack-supprted sensr. The backpack is uniquey cnstructed permitting measurement f tta fied r gradient with bth hands free. This ptin prvides greater versatiity and fexibiity, which is particuary vauabe fr high-prductivity surveys r in rugh terrain.

19 Versin 6 -- Techngy Devepments One f the main differences between GEM and ther manufacturers is GEM's 20+ year, cnsistent fcus n deveping eading-edge magnetic techngies. This cmmitment has ed t many nnvatins in sensr techngy; signa cunting; firmware and sftware; and Hardware and cnse design. The recent reease f v6.0 f the GSM- 19 system prvides many exampes f the ways in which GEM cntinues t advance magnetics techngies fr its custmers. Enhanced data quaity: 25V imprvement in sensitivity (new frequency cunting agrithm) new inteigent spike-free agrithms (in cmparisn with ther manufacturers, GEM des nt appy smthing r fitering t achieve high data quaity) Imprved peratina efficiency: Enhanced psitining (GPS engine with ptina integrated externa GPS and rea-time navigatin) 16 times increase in memry 32 Mbytes (ptina). 4 Mbytes standard 1000 times imprvement in prcessing and dispay speed (RISC micrprcessr with 32-bit data bus) 2 times faster digita data ink (115 kbaud thrugh RS-232) Innvative techngies: GEM's Prven Overhauser System In a standard Prtn magngfp/pgfej. current is passed thrugh a ci wund arund a sensr cntaining a hydrgenrich fuid. The auxiiary fied created by the ci (MOO Gauss) parizes the prtns in the iquid t a higher therma equiibrium. When the current, and hence the fied, is terminated, parized prtns precess in the Earth's fied and decay expnentiay unti they return t steady state. This prcess generates precessin signas that can be measured as described bew. Overhauser magnetmeters use a mre efficient methd that cmbines eectrnprtn cuping and an eectrn-rich iquid (cntaining unbund eectrns in a svent cntaining a free radica). An RF magnetic fied - that crrespnds t a specific energy eve transitin - stimuates the unbund eectrns. Instead f reeasing this energy as emitted radiatin, the unbund eectrns transfer it t the prtns in the svent. The resuting parizatin is much arger, eading t strnger precessin signas. Bth Overhauser and prtn precessin, measure the scaar vaue f the magnetic fied based n the prprtinaity f precessin frequency and magnetic fux density (which is inear and knwn t a high degree f accuracy). Measurement quaity is as cacuated using signa ampitude and its decay characteristics, Vaues are averaged ver the samping perid and recrded.

Current is passed thrugh the p which fwing the Turn-Off, prduces a primary magnetic fied (H) bth inside and utside (Figure B1). This primary fied induces vrtex current patterns, which energize cnductrs and which in turn create their wn secndary magnetic fied (Bs). The rate f change f the decaying secndary magnetic fux (dbs/dt) is measured as the vertica (Hz), in-ine hriznta (Hx) and/r crss ine hriznta (Hy) vectr cmpnents n surface using an air-cre sensr ci. These measurements f the TEM decay (20 g-time sices) are taken during the "Off-Time", using a 30 cyce/sec, base repetitin rate. In keeping with the industry standard, the primary fied is aways cnsidered psitive up inside the p and negative dwn utside. Simiary, fr secndary EM fieds, the receiver ci is riented psitive vertica up fr the Hz cmpnent. The cnventin fr In-Lp surveys, has the in-ine cmpnent, Hx riented either psitive east (fr grid EW ines) r nrth (fr grid NS ines). The Off-Lp survey cnventin differs, with the receiver ci rientatin fr Hx pinting psitive away frm the transmit p (fr EW r NS ines).

Of particuar imprtance is its appicatin in cases where the dri ing is beieved t have missed the target f interest. A 3-D brehe survey can effectivey determine the directin and distance frm the dri he t the cnductr by measuring tw rthgna secndary fied cmpnents in additin t the axia cmpnent.
