INTRODUCTION
During the period from October 11, 1986 to November 7,
1986 a ground magnetic survey was carried out over the 36
unpatented claims which make up the Orsina Property. The pre-
ceeding linecutting (Sept. 2ltX86 to Oct. 30/86) and magnetic
survey were carried out by Robert S. Middleton Exploration
Services Inc. under the author's supervision.
PROPERTY. LOCATION and ACCESS
The property consists of 36 unpatented mining claims
which are listed in the accompanying technical data statement.
These claims are situated in the central portion of St. Laurent
Township some 60 air miles northeast of Cochrane, Ontario and
roughly 3.5 miles west of the Ontario/Quebec border (see front
ispiece),
Access to the property is by helicopter from Cochrane,
Ontario.
PREVIOUS WORK
Newmont Exploration of Canada Ltd. has filed for assess
ment credits, an airborne magnetic and electromagnetic survey
which covered the ground presently held by Orsina Resources Ltd,
While a number of magnetic anomalies were encountered, no
electromagnetic anomalies were detected on what is now the Orsina
Property.
No other work is known to have been carried out on the
claims in question.

REGIONAL GEOLOGY
St. Laurent Township is situated in the northwestern portion
of the Abitibi Subprovince referred to as the Burntbush Greenstone
Belt. As the region is covered by extensive, thick, Pleistocene
glacial and glaciolacustrine deposits few details of the regional
geology are known. Regional Geology maps such as Ontario Depart
ment of Mines Map 2161 are therefore based, in large part, on
geomagnetic interpretation along with only scattered areas of
bedrock exposure ( see Fig. l, page 3)*
Regionally the Burntbush Area is underlain by Early Pre
cambrian (Archean) supracrustal rocks of volcanic and sediment
ary origin which have been intruded by Archean felsic and mafic
intrusives.
Regionally extensive oxide facies iron formation are the
most striking geomagnetic feature and provide the best indica
tion of regional geological trends under the extensive pleistocene
deposits.
The Burntbush Greenstone Belt is tenatively interpreted
to be synformal with the iron formations which extend from the
Casa-Berardi area in Quebec through Bradette, Noseworthy,
Hoblitzell anc* Blakelock Townships being repeated on the south
limb through Newman, Tomlinson, Hurtubise and St. Laurent Town
ships.
The area between the north and south limbs are interpreted
to be underlain by felsic to intermediate metavolcanic rocks and

felsic intrusives, while south of the south limb mafic meta-
volcanic rocks predominate.
Regionally the supracrustal rocks are thought to strike
from east-northeast to northeast with very steep dips.
Economically, the Orsina Property is situated roughly 29
kilometers southwest of the recent Inco/Qolden Knight "Golden
Pond" discovery in Casa-Berardi Township and 16 kilometers
southeast of Newmont's recent discovery in Noseworthy Township
( 0.116 ozs./ton Au over 25 ft. including 0,2? ozs./ton Au over
8 ft.) l .
SURVEY METHODS
a) Linecutting
The 800mE Tie Line was established at the #1 post of claim
L. 879305 as was cross line lOOmN.
The 800mE Tie Line was cut from lOOmN to 1050mS on a bearing
of 30 degrees azimuth. All the Tie Lines and the 0+00 Base Line
were established at the same bearing.
The JfOOmE Tie Line was cut from IfOOmN to 800mS, the 300mE
Tie Line was cut from !600mS to 2000mS, the 0+00 Base Line was
established from llfOOmN to l?OOmS, the JfOOmW Tie Line was cut
from 0+00 to 800mS, the 500mW Tie Line was cut from 2200mN to
1/fOOmN and finally the 800mW Tie Line was cut from ^OOmN to 2125mN.

Cross Lines were established at 100 meter intervals per
pendicular to the afore-mentioned Base and Tie Lines. Cross
Lines were cut and numbered from 2200mN to 2000mS inclusive.
In total 42.978 miles of line was cut to cover the 36
claims,
b) Magnetic Survey
The magnetic survey was carried out by two operators one
of whom utilized a Geometrics Precision Proton Magnetometer
model G-816 while the second operator utilized an EDA Precision
Proton Magnetometer model PPM-350.
A third Precision Proton Magnetometer-model EDA PPM-IfOO was
utilized as a recording base station to measure, record and
ultimately correct for diurnal variations in the earth's mag
netic field.
Readings, which were taken on all base lines, tie lines
and cross lines were normally taken at 25 meter intervals with
readings being taken at 12,5 meter intervals in areas of anom
alous magnetic suceptibility. A total of 3^29 stations/readings
were established/recorded giving an average of 95i readings
per claim.
SURVEY RESULTS
Results of the survey are plotted and contoured on the
accompanying maps entitled " Magnetometer Survey", The ground
scale used was 1:2500.
With a background of 58,000 gammas, the magnetic relief
MOUNTJOY EXPLORATION AND CONSULTING SERVICES
-6-
varies between plus 131 (58,131) and plus 13,113 (71,113)
gammas.
As a result of the magnetic survey a large number of
anomalies have been outlined. However, for practical purposes
almost all the anomalies result from the same cause which is
oxide facies iron formation or to be more specific magnetite.
The iron formation typically occurs in lenses which are
commonly slumped and or drag folded. Lenses of magnetite rich
iron formation extend from XL 1500 meters North on the 0+00
Base Line to XL 1500 meters South at 800 meters East.
The north sheet is dominated by one major band of oxide
facies iron formation which strikes roughly 30 to 35 degrees
azt. at about 200 meters west from XL 200 mN to XL 1500 mN,
At 250mW on XL HOOmN a splay is developed and a lense of
iron formation striking roughly 355 degrees extends to 1^00 mN
at 700 mW.
Two smaller lenses, subparallel to the major band extend
from XL JfOO mN to XL 800 mN at roughly 100 mE and ifOO mE.
On the South Sheet the two smaller subparallel lenses
amalgamate at XL 100 mN to produce one band which extends to
XL 1100 mS at 700 mE. This band forms what can be envisioned
as the eastern half of a large horseshoe shaped anomaly which
surrounds a magnetic low centered at XL 1000 mS/275 roE.
While the cause of this low is still unclear at this time,
the presence of a felsic intrusive unit cannot be ruled out.
MOUNTJOY EXPLORATION AND CONSULTING SERVICES
-7-
While this may explain the concave nature of the western
band of iron formation this feature could also be explained
by structural or depositional causes. Similarly the magnetic
low may be caused by what are commonly known as dipole effects,
which are common adjacent to areas of high magnetic suceptibility.
Other examples of dipole effects are present at - XL ifOO mS/O+OO
BL, XL 300 mS/100 mW, XL 0/325 mW, XL 300 mN/225 mW, XL 500 mN/
Jf25 mW, XL 600 mN/250 mE, XL 700 raN/0+00 BL and XL 1000 mN/300 mW.
As the presence of extensive oxide facies iron formation
tends to dominate the geomagnetic picture little can be discerned
regarding the lithologies of the surrounding rocks which were
originally interpreted to be felsic to intermediate metavolcanic
rocks. As a result the surrounding rocks are still interpreted
to be felsic to intermediate metavolcanics however, it is worth
noting that the presence of clastic metasedimentary units
cannot be ruled out.
In the extreme northwest corner of the claim group is an
isolated anomaly which covers much of claim L. 879280. It's
moderate magnetic suceptibility combined with it's roughly
elliptical shape gives rise to the interpretation that this
anomaly is caused by a mafic intrusive rock type such as
gabbro or diorite.
Structurally the rock units are thought to strike from
30 to ifO degrees azimuth with a steep dip to the east-southeast.
Inconclusive evidence of drag folding can be seen on XL
0+00 from 300 mE to 300 mW and on XL JfOO mS from 50 mE to 200 mE.
MOUNTJOY EXPLORATION AND CONSULTING SERVICES

No clear evidence of major fault linaments can be dis
cerned at this time.
CONCLUSIONS/RECOMMENDATIONS
The survey has successfully outlined the oxide facies
iron formation present within the boundaries of the claim
group. The ground magnetic survey has better defined subpar-
allel lenses, subtle warps and splays the previous airborne
magnetic surveys were unable to discern.
Recommendations for further work include a reconnaisance
style Induced Polarization Survey concentrating on the oxide
facies iron formation particularily where it appears to be
distorted. The purpose of this survey would be to try to
outline units of sulphide facies iron formation and or graphitic
horizons, both of which host gold mineralization elsewhere in
the region.
Subsequent Induced Polarization anomalies should be tested
by diamond drilling.

PPM-300 Total Field Magnetometer This model Is the most advanced Held magnetometer in the world. The PPM-300 measures the earth's magnetic field lo sensitivities of 0.1 nT and displays the resulting data on the high visibility LCD. The automatic power-off capability prevents the un necessary consumption of power.In addition lo providing the total Held magnitude and time, II also records on Its internal solid state memory, the grid co-ordinates (lino and station) and reading error. The non-volatile memory can store 1384 data blocks, eliminat ing any need to record data manually. Should the operator wish to recall and interrogate the memory for previously stored parameters in any one data block such as the total field, the lime the reading was taken, the line and position number and/or the error, he may do so with the data recall feature incorporated into the software. Accumulated data Is regularly trans ferred Into either the DCU-400 Thermal Printer or the DCU-200 Magnetic Cas sette Recorder. Dala may also be ted directly into small desk top computers for other interpretative uses. Two sensor configurations, as shown here, are available. The in-line sensor attached directly to the electronics console leaves the operator with com plete freedom from cables. The remote sensor Is recommended for use in dense bush or iug(juU lorrain.
PPM-400 Base Station MagnetometerThis Integral sensor and console package Is the first magnetometer specifically designed for base station applications, which Include airborne data verification and ground survey corrections. It's unique in-line con figuration allows It to be set up above the ground and away from hazards an local magnetic interferences. As with the PPM-300, a remote sensor con figuration Is also available. Unlike other base station magnetometers which have limited versatility, the PPM-400 Is completely programmable through Its keypad, and has the abllit to perform diurnal and reference field corrections lo data collected by the PPM-300. All data is stored internally In a high capacity 2779 data block m volatile memory which Is then either transferred Into the DCU-400 or DCU-200. Also unique to this instru ment Is a "snooze" alarm used to cor serve power. In simple terms, the microprocessor acts as an alarm cloc and turns power-draining circuits off following each reading and auto matically powers up just prior to tak ing a subsequent reading.
