1. INTRODUCTION
In July of 2018, Richmond Minerals Inc. retained Geophysique TCM Inc. of Val d’ Or,
Quebec to conduct Induced Polarization/Resistivity and Ground Magnetic surveys over the
Agaura West Grid of the Ridley Lake Project, situated in Rollo Township, Ontario. The
survey took place during the period of August 8th to August 15th, 208. Altogether 9.6 km of
ground magnetic and 9.6 km induced polarization/resistivity surveying was completed. The
East and West Grids of the project have common boundary. The Agaura East Grid received
IP/Resistivity surveys in two phases and a ground magnetic survey (F. L. Jagodits 2016
and 2017). The Interpretation parts of the reports and the Interpretation Map is included in
the Appendix.
The operational report of Geophysique TCM Inc. is included in digital format of this
report.
2. LOCATION AND ACCESS
The Ridley Lake property is in Rollo and Raney Townships, Porcupine Mining Division,
and lies within NTS 41 O/15 (Figure 1). The property is located 40 km south-southwest of
the Town of Foleyet, and approximately 120 km west-southwest of Timmins, Ontario. The
grid that was prepared for the geophysical surveys is illustrated on Figure 2. Personnel
employed are listed in Table I, found in the Appendix.
Originally, the access to the property has been by float equipped aircraft landing on
Ridley Lake. Presently, logging roads leading from Hwy. 101 to the property provide
access.
3. PROPERTY DESCRIPTION (from F. L. Jagodits, 2016)
The geophysical surveys cover nine (9) contiguous, unpatented mining claims. They are
in Rollo Township, Porcupine Mining Division, District of Sudbury, in northwestern
Ontario. The following claims were surveyed: 121851, 129188, 129189, 184575, 192603, 232366, 263117, 278487 and 340091. The claims covering the entire grid are illustrated on
Figure 2. The figure shows the claims that were obtained from the government data base.
4. PREVIOUS WORK (from Hillier, D., 1989)
“Two gold showings exist on the Carson/Black Gregor (now the Ridley) property. The
showings are known as the Cyril Knight and Agaura prospects. During 1932, the two
11

showings were controlled by two separate mining companies; the Cyril Knight Prospecting
Company Limited and the Agaura Exploration Company Ltd.
The Cyril Knight prospect was trenched and in 1932 described as a gold bearing quartz
vein hosted by schisted andesite lavas with an indicated length of approximately 800 feet
striking N65°E and dipping 80°SE. The vein was exposed in a trench for 430 feet, with a
maximum width of 10 feet and pinched out sharply to the west and narrowed to a series of
stringers to the east. The quartz was described to be of the white glassy variety and was
highly fractured in a direction parallel to the strike of the vein. The vein reportedly carried
a small amount of pyrite and minor native gold (Rickaby 1935).
Previous Carlson geologists interpreted this zone to be a cherty exhalative horizon within a
series of schisted, carbonatized, mafic volcanics (Rio, 1983). No drilling was carried out on
this zone during the recent drill program.
The Agaura prospect was also trenched during the 1930's and was described as consisting
of two similar-striking zones of gold mineralization hosted in quartz-pyrite veins. The
"south' zone contained three quartz-pyrite-ankerite +/- Au veins cutting arkosic rock. The
centre vein, which was the largest, had a maximum width of 13 inches and a length of
approximately 80 feet. One isolated assay reported 0.7 oz/ton Au over 8 inches.
Approximately 500 feet north, a highly schistose zone up to 12 feet in width with coarse-
grained pyrite and lenses of quartz was located within a greenstone band. Only low gold
values were obtained from this zone, which was traced for 500 feet on a strike of N80°E.
Approximately 50 feet south and parallel to the sheared zone was a rusty, carbonatized
quartz feldspar porphyry dike up to 15 feet wide (Rickaby 1935).
No further work was done on the properties until 1982 when Carlson Mines Ltd. staked a
group of 20 claims covering both showings. The property was inspected, for Carlson by
Phendler (1982) who reported several anomalous Au values obtained from the 1932/33
trench which exposed the northern volcanic-hosted carbonatized chlorite-pyrite-quartz vein
shear zone. At the same time, Newmont Exploration of Canada Ltd. visited the property
and collected several samples which generally confirmed Phendler's values. Both showings
were IP tested and results indicated that a dipole-dipole array could be used to trace the
known mineralized zones.
During the summer of 1983, systematic geological and geophysical surveys were carried
out over a 20 claim area of the property. The results of the geological mapping are
presented in a report by Rio (1983) which includes a 1"-200' scale map. Geophysical work
included a magnetometer survey at 25 ft. 50 ft. and 100 ft. stations; a VLF-EM survey at
100 ft. stations and a time-domain IP survey using a dipole-dipole array with a=50'. Results
indicated that both showings displayed coincident magnetometer and IP anomalies of
approximately 3x and 4x background respectively.
A major IP anomaly was outlined immediately south of the Agaura showing corresponding
to a strong VLF-EM conductor; in addition to other significant, isolated IP and VLF-EM
anomalies. Magnetics generally appeared to reflect the distribution of massive mafic
14
volcanic flows containing up to 5% magnetite and outlined a probable diabase dike (Hill,
1986).
During the summer of 1985, a stripping, blasting and systematic sampling program was
carried out in the area of the Agaura showing. Results from this program are presented in a
report by Hill (1986). Hill distinguished several significant units within the stripped area
and his results are included with the present data in this report”.
“During the month February 1989 a diamond drilling program was carried out by Black
Gregor Explorations Ltd. on the Carlson Mines ltd – Black Gregor Explorations Ltd. joint
venture Ridley Lake Swayze Area Property. A total of 13 holes, 8,106 feet, of BQ size
drilling was completed. The location of the holes is shown on Figure 3,
The general stratigraphic sequence, in the area that was drill tested, consist of a lower
mafic pyroclastic unit in the north which is conformable overlain by approximately 300 ft
of massive mafic flows which host auriferous shear zones, overlain by an 800-foot-thick
series of highly altered and deformed felsic pyroclastics. A quartz feldspar porphyritic
intrusion cuts the middle mafic flow at its upper contact.
Several geologic features appear to be significant in defining areas of potential gold
mineralization;
i) Areas with shear zone development
ii) Areas of intense carbonatization and the presence of pyrite mineralization
iii) Spatial association of felsic intrusives of alkaline composition (Hilier, D, 1989)”
The results of the ground geophysical surveys were once again examined, and their
interpretation, conclusions and recommendations are included in a memorandum entitled
“Compilation of Geophysical and Geological Data, Ridley Lake (Swayze) Property, Raney
and Rollo Townships, District of Sudbury, Porcupine Mining Division Ontario (Jagodits,
F. L., March 2014). The memorandum and a page-size copy of the interpretation map are
included in the Appendix and on the Archive DVD.
The primary conclusion of the investigation is that the Agaura type gold mineralization
provided distinguishable IP/resistivity signatures. The correlation between IP/resistivity
and Cyril Knight Showing is not as exemplary because of lack of data; however, a
signature would probably be obtained by properly conducted survey (Jagodits, F.L,
March 2014).
The IP/resistivity survey also detected two targets (Targets 4 and 7) where the apparent IP
responses are anomalous but correlated with low apparent resistivities. In both cases the IP
trends are associated with or in direct correlation with VLF-EM conductors that may show
conductive structures. Possible sources of the IP/resistivity responses include non-magnetic
sulphides and graphite (Jagodits, F. L., March 2014).

During 2014 and 2015 Richmond Minerals Inc. conducted prospecting work over the
property and reported in: Nitescu, B., Hawkins W. and Carter, G., 2014; Nitescu, B.,
Hawkins, W. and Currah, L., 2015a and Nitescu, B., Hawkins, W. and Currah, 2015b.

In 2015, Richmond Minerals Inc. retained ClearView Geophysics Inc. of Brampton
Ontario, to conduct Spectral IP/Resistivity and ground Magnetic Surveys covering the
Agaura East Grid (Jagodits, F. L., 2016). Based on the survey results two drilling programs
were completed (Nitescu, B. and Hawkins, W, 2016. Report on Diamond Drilling conducted
on Claims 4275237 and 4275238 of the Ridley Lake (Swayze) Property, Rollo and Raney
Townships, NTS Sheet 041O/15, Work Period: July 06 – July 26, 2016; and Nitescu, B. and
Hawkins, W. 2016. Report on diamond drilling conducted on claims 4275237, 4275238 and
4275274 of the Ridley Lake (Swayze) Property, Rollo and Raney Townships. (Submitted to
the Ontario Ministry of Northern Development and Mines on behalf of Richmond Minerals
Inc.)
To explore to greater depth, ClearView Geophysics was contracted in November 2016
to conduct a Spectral IP/Resistivity survey covering the western part of the Agaura East
Grid, employing increased electrode separations. The surveyed lines are: 0E, 75E, 150E,
225E, 300E and 375E. The survey took place during the period of November 8th to
November 16th., 2016, (Jagodits, F. L, 2017).
5. GEOLOGY (from Hillier, D., 1989)
For the sake of completeness, the regional and local geology from Hillier are included.
“The Carlson/Black Gregor property is underlain by part of a major sequence of early
Precambrian volcanics and sediments referred to as the Swayze volcanic complex
(Goodwin and Ridler, 1970) or the Swayze-Deloro metavolcanic-metasedimentary belt
(Thurston et al., 1977).
The Swayze volcanic complex is an E-trending belt composed, from the margins inward,
of mafic metavolcanics succeeded by metasediments with several centres of felsic
volcanism along its length. To the north, the Deloro volcanic complex underlying
Horwood Lake and Reeves-Penhorwood Townships consists predominantly of mafic
metavolcanics with only minor metasediments. Together the two complexes form the
Swayze Deloro belt (Thurston et al., 1977 from Hill, 1986).
Mapping of the Swayze complex by Rickaby (1934) defined a "basement" greenstone
assemblage of mafic to felsic flows and pyroclastics overlain by younger, essentially
sedimentary but also felsic volcanic rocks known as the Ridout and Swayze series.
Donovan (1965, 1968) defined a more continuous sequence of cyclical mafic-felsic
volcanism with intermixed volcanic sedimentation south of Rollo Township. Age
relationships among mafic metavolcanics, felsic metavolcanics and metasediments were
found to be variable (Hill, 1986).
Thurston et al. (1977) summarized the lithologic descriptions of the Swayze-Detoro belt
rocks. Mafic to intermediate metavolcanics are predominant throughout the area and
17
include massive, pillowed, foliated, fragmental (breccia plus tuffs) and porphyritic types.
Intermediate to felsic metavolcanic rocks are less common. A major linear zone of massive
to porphyritic dacite with associated fragmental and epiclastic sediments extend through
the central portion of the Swayze complex just south of Ridley Lake. Elsewhere, felsic
metavolcanic flows and tuffs form relatively thin bands within intermediate to mafic
metavolcanics. All volcanics have been metamorphosed largely under greenschist
conditions and locally under almandine-amphibolite conditions (Hill, 1986).
The metasediments, in order of importance, include greywacke, arkose, conglomerates,
quartzite and argillite. Also, intercalated with mafic metavolcanic are thin bands of iron
formation or ferruginous metasediments of silicate carbonate or sulphide association. Much
of the rock originally mapped as sediments by Rickaby (1935) has been re-interpreted as
felsic pyroclastic material. It is apparent that metasediments make up no more than 10/% of
exposed Swayze-Deloro belt rocks. The most extensive band of metasediments (originally
named Ridout series) extends through the southern portion of the Swayze belt and, together
with a smaller band in Halcrow and Denyes Townships (previously called the Swayze
series) are referred to collectively as the Ridout metasediments (Hill. 1986).
The Swayze-Deloro metavolcanic-metasedimentary belt has been tightly folded into a
series of synforms and antiforms which, due to the lack of geological and structural
control, are not well defined. Bell (1964) implied that a major east-west synclinal structure
south of Rollo Township was overturned with a north-dipping axial plane. Stratigraphic top
indicators on the north limb of the syncline faced south, but beds dipped steeply north.
Mapping carried out in 1985 on the Carson/Black Gregor property appears to confirm his
interpretation (Hill, 1986).
The most common felsic intrusives have been emplaced as dikes and sills of quartz-
feldspar porphyry with occasional granitoid stocks. Mafic to ultramafic rocks have
intruded the metasedimentary-metavolcanic sequence as diorite to gabbroic sills and stocks
of early Precambrian age and, more recently, as three distinct diabase dike sets (Hill.
1986)”.
6. GEOLOGY OF THE AGAURA SHOWING
The following sections has ben taken from a report Hill of Carlson Mines Ltd. And Ridley
Lake Minerals Corporations Corp., Detailed Geological mapping and sampling of the
Aguara Showing, Ridley lake Property (1986).
“The general stratigrahic sequence in the area consist of a lower mafic pyroclastic unit (in
the north) conformably overlain by approximately 300 feet of massive, rarely pillowed
mafic flows, which hosts clorite + pyrite + J – gold shear zones, overlain by an 800 foot
thick series of highly altered and deformed felsic pyroclastics which are host to apparently
auriferous quartz veins (the “south zone” of Rickaby, 1935). A quartz feldspar porphyritic
intrusion cuts the middle mafic flow unit at its upper contact and appears to have been
intruded as a slightly discordant sill-like body. Uppermost in the section, south of the area
18
of defined mineralization, is thick sequence of intermediate to felsic flows cut be a narrow
diabase dyke.”
7. THE GROUND GEOPHICAL SURVEYS
7.1 The Grid
The grid consists of 12 north-south lines that are 75 m apart and a base line, with
pickets every 25 m.
7. 2 Ground Magnetic Survey
(Detailed discussion instrumentation, survey procedures, data reduction and
presentation are included in Simard, J., 2018.)
Instrumentation and Survey Procedures
The survey was conducted employing a GEM GSM-19 Overhauser proton
precession magnetometer. Observations were made at every 12.5 m along the
lines and the base line. The integration time was 2 s. The diurnal variations of the
magnetic field were recorded every 10seconds using a GSM-19 base station
system. The corrected final data base was geo-referenced to the NAD83 datum,
UTM- Zone 17N.
Presentation of the Results
The corrected data are presented on base maps showing planimetric features,
claims and claim numbers at a scale of 1:2 500.
The following maps were prepared:
- Postings and profiles of the Residual Total Magneti Intensity (RTMI)
- Postings and Profiles of First Vertical Derivative of the RTMI.
- Contours of the Residual Total Magnetic Field (RTMI)
- Contours of the First Derivative of the RTMI.
The corrected data bases of the East and West Grids were combined the following
maps were produced, that are shown as Figure 3 and Figure 4.
- Contours of the Residual Total Magnetic Field (RTMI)
- Contours of the First Derivative of the RTMI.

7.3 Induced Polarization /Resistivity Survey
(Details of the instrumentation, survey procedures, data processing and
presentation are included in Simard, J. 21018.)
Instrumentation and Survey Procedures
The dipole-dipole electrode array was utilized; the electrode spacing was 50 m for
dipole separation of n=1 to n=66 and 100 m for dipole separations of n=8 and
n=9.
“The induced polarization equipment consisted of a transmitting and receiving
apparatus using a commuted signal. A motor generator drove the TX-III GDD
instrumentation transmitter capable of supplying 1.8 kW of continuous power.
Stainless steel electrodes were used to inject ta stable current. The bipoloar current
waveform had an 8-second period with 50% duty cycle.
The primary voltage, denoted Vp and chargeability M were measured using an
Eltec Pro Instruments Time Domain Receiver. The decay curve was separated into
20 pre-programmed slices (Simard, J., 2018)”.
Data Processing and Presentation of the Results
(The maps, pseudo-sections and inversion models are included in the Appendix.)
The computed apparent resistivity, chargeability, profiles of the RTMI and 1st
Derivative of RTMI, and the 2D inversion of the resistivity and chargeability are
presented as pseudo-sections for each survey line. (detailed description of the 2D
inversion is in Simard, J., 2018).
The apparent resistivity and apparent chargeability obtained at an=2 are also
presented as contour maps. For ease of studying the variations of the parameters
from line to line, stacked pseudo-sections of the apparent resistivity and
chargeability were also prepared.
The presentation of the results also includes the following maps:
- Contour maps of apparent resistivity and chargeability n=2 of the
combined data of Agaura East and West Grids at a scale of 1:2 500.
- Contour maps of resistivity and chargeability derived from 3D
inversion of the combined East and West Grid data, at 50 and 100 m
vertical depth slices.

8. DISCUSSION OF THE RESULTS
8.1 Magnetic Survey
The magnetic anomalous trends are the southwesterly continuation of the
magnetic horizons of the East Ridley Grid. The northeast-southwest trending
horizons of both grids represent a succession of variably magnetic, steeply
dipping volcanic horizons. The prominent, northeast-southwest striking horizon
identified as M1 is associated with the Agaura gold occurrence. Several of the
earlier drill holes intersected this magnetic horizon. The encountered rocks are:
intermediate to mafic composition volcanics, intermediate to mafic composition
intrusive and feldspar porphyry. The association between the gold occurrence is
not diagnostic. The somewhat lower magnetic background field, south of the
above mentioned M1 anomaly suggests increased felsic component in the
volcanic assemblage.
The outlined induced polarization trends are no-magnetic, although partial
correlation is also observable. It is notable that IP Trend RW-5 follows the
northeast-southwest trend of the geology, suggesting a possible formational
origin.
North-northeast and west-northwest striking fault and/or shear zones were
interpreted from the dislocations of the magnetic patterns.
8.2 Induced Polarization/Resistivity Survey
General Comments
The approximate surface expressions of the sources are indicated on the Interpretation Map. The range of chargeabilities is given on the Interpretation
Maps as multiples of the background chargeability near the anomaly.
The average apparent resistivity in terms of thousands of ohm-m is also shown on
the Interpretation Map of the West Grid (Figure 6). The symbol “D” alongside of
the anomalous zone indicator signifies that the anomalous responses were
detected at the larger dipole separations that may indicate a source located at a
greater depth. The depth of the source is suggested by the 2D inversions of the
pseudo-sections.
The traces of the 1989 and 2017 drill holes are shown on several maps; the geology is colour coded on the left side of the trace, the estimated pyrite content is colour coded on the right side of the trace together with the gold content shown as bars. The hole traces with the above information are included on following maps (1:2 500 scale),: (a) base map of the west grid, (b) as an overlay to the contour of apparent chargeability at n=2, West Grid, (c) as an overlay to the 3D P inversion apparent chargeability @50 m depth
23
slice, West Grid and (d) as an overlay to the 3D inversion apparent chargeability @100 m depth slice, West Grid (Figures 7, 8, 9 and, 10).

The IP Trends
Seven IP anomalous horizons discovered by the survey that are identified by the same number if thy are continuations of a trend identified on the East Grid. The trends are sub-parallel and confirm with the northeast trending geology. The trends are identified Trends RW-1, RW-4, RW-5, RIP-6 and the discontinuous RW-7.
The significant trend is RW-1, which is the westerly continuation of the of Trend RIP-1A of the East Grid is approximately centred about the Base Line extending to L600W, albeit the signatures are feeble on Lines 600W and 525W. The Agaura Showing is located between Lines 75W and 150W. The anomalous signature is wide along L75W, suggestive of wider source, however, the signature of L150W better defines a narrower source. The trend is associated with apparent resistivities exciding 10 000 ohm-m, suggestive of possible alteration.
The entire zone was extensively drilled; however additional testing is can be considered after careful correlation between drill logs and the pseudo-sections and inversions; the possible locations are along Lines 225W. 375W and 525W. It is noted that drill holes logs of all the holes recorded < 1% pyrite.
The prominent apparent chargeability anomalous trend is RW-5, extending from L225W to L750W, in the north of the grid; it is the extension of Trend RIP-5 of the East Grid. The trend is associated with apparent resistivities that are 1000 ohm-m or lower. It was suggested earlier that the trend may represent a formational feature. The signatures along L750W, 825W and 900W are complex. The pseudo-sections imply wider sources that are illustrated by the 2D inversions. The inversions indicate that the depth of the source(s) may be 100 m (?).
The onset of Trend RW-4 is noted at the south ends of the pseudo-sections from L75W to L375W. It is characterized by apparent chargeabilities exceeding 10 mV/V. RW-4 is the westerly extension of RIP-6 of the East grid. A formational source is suspected; as it is, it is of no further interest for the time being.
Trend RW-6 represents the commencement of anomalous IP responses that were observed at dipole separations n=8 and n=9, indicative of deeper sources. The associated resistivities exceed 10 000 ohm-m. It is noted the wide, IP anomalous responses that are observed at the large dipole separations (n=7, 8 and 9) of L900 may be in part of the northwesterly extension of RW-6.
Trend RW-7 is detected intermittently at larger dipole separations indicating
greater depths to the sources. The trend is located between Trend RW-5 in the
north and RW-1 on the south. and is well defined along Lines 525W 375W and
300W, Significantly, the associated apparent resistivities are more than 10 000
ohm-m. The trend is worthy of drill testing.

9. COMCLISIONS AND RECOMMMENDATIONS
The induced polarization/resistivity survey defined seven anomalous trends that generally
follow the east-west, northeast-southwest trending geology. Trend RW-1 is the westerly
extension of RIP1-A of the Ridley East Grid. Drill testing of RIP-1A revealed anomalous
gold values. Trend RW-1 was drill tested at numerous locations by earlier operators (Fig.
7) . Based on the results of the present data additional drill holes are offered for
consideration, after the detailed examination and compilation of the earlier drilling
results. The locations of the drill are along Lines 225W, 300W and 375W. The
specifications are below.
Trend RW-7 depicts deeper seated sources that are associated higher apparent
resistivities, exceeding 10 000 ohm-m. The trend is about 125 north of and subparallel to
Trend RW-1. Drill testing of the trend is recommended along Lines 300W, 375W and
525W.
Trend Rw-5 is the westerly extension of RIP-5 of the Ridley East Grid. It is characterized
by high chargeabilities and low apparent resistivities. The non-magnetic source may be
considered as a formational feature. One location is given for a possible drill testing.
Only of the onset of Trend RW-4 is detected, that is the westerly extension of RIP-4 of
the Ridley East Grid. Trend RW-6 may signify the start of a deeper source. As it stands,
further work along Trends RW-4 and 6 is not recommended.
The explanation of the deep-seated anomaly along L900W is enigmatic; further survey
work to the west will be required to better define the source. The recommended drill
locations are in the table below.
Recommended Drill Hole Locations

RW-1 225W 0+25N -45° Grid South 125 m

Subject: Compilation of Geophysical and Geological Data,
Ridley Lake (Swayze) Property, Raney and Rollo Townships, District of Sudbury,
Porcupine Mining Division Ontario
Date: March 18, 2014
1. Preamble
In 1983, ground geophysical surveys were conducted covering the claims of
Carlson Mining Ltd. in the Ridley Lake area. The purpose of the present
investigation was to define the geophysical signatures of the Cyril Knight and
Agaura Showings and to locate similar signatures from the available data.
The investigated Ridley Lake Property lies within NTS 41 O/15 and centred about
UTM co-ordinates (NAD 83, Zone 17) 371500E and 5303500N or 17° 52’ 29”N
latitude and 82° 43’ 06” W longitude. It comprises 20 unpatented single mining
claims in one contiguous block.
The property is located approximately 50 km east of Chapleau, Ontario and
is120 km southwest of Timmins, Ontario.
The original 20 unpatented single mining claim block was extended. In the
following it will be referred to as the Expanded Claim Block
The selected targets, that are based on the IP/resistivity data are listed and
discussed in the attached Table 1.
The result of the compilation is on the Compilation Map, at a scale of
1 inch = 200 ft.

Ontario Geological Survey, INPUT/magnetometer survey, 1981 (Swayze)
3. The Surveys
3.1 Magnetic Survey
The posted magnetic data were contoured at a basic contour interval of
100 nT. There are isolated locations where steep gradients were observed that
may be due erroneous observations. A general magnetic low correlates with
the mapped diorite in the southwest corner of the claims. The diorite is cut by
a northwest-southeast dyke. Another possible northwest-southeast dyke is
detected in the northwest of the claims. Most of the claim area is shown to be
underlain by mafic volcanics. The magnetic data suggest that the magnetic
properties of the mafic volcanics are variable as expressed by the distinct
magnetic feature in the east central claim area.
Closer contouring of the data would reveal far more detailed information;
however, the recommended magnetic surveys will provide far improved
magnetic maps.
3.2 VLF-EM Survey
The collected data are of good quality. Numerous, nearly east striking
conductor were determined. They vary in length from 100 ft. to 2000 ft. They
are most likely caused by conductive contacts, shears and faults. The axes of
50
the conductors are shown on the compilation map. Correlations with magnetic
and IP features are noted in the attached table.
3.3 Induced Polarization/Resistivity Survey
As noted above the survey was incomplete. The survey covered the northeast
corner, the general area of the Cyril Knight Showing and the approximate
southeast corner of the claim group that includes the Agaura Showing
.
The dipole-dipole array was utilized using an electrode separation of 50 ft.
Observations were made at dipole separations of 1 and 2.
The electrode separation of 50 ft., and the dipole separations of 50 ft. and
100 ft. afforded an approximate 35 ft. of effective depth of investigation.
Consequently, only the near surface sources were detected.
In Table I, the amplitudes of the IP responses are noted in terms of the local
background. The average or the spread of the apparent resistivities associated
with the IP targets are given in 1000’s of ohm-m.
Excellent correlation is recognized between the Agaura Showing and IP
Target 1 (up to 6xBG) which is associated with apparent resistivities
>10 000 ohm-m. The target is open to the east. Unfortunately, IP/resistivity
survey coverage is incomplete and it is difficult to establish correlation
between the Cyril Knight Showing and the geophysical data. It is noteworthy
that IP Target 2b is on strike with the showing, at its northeastern end.
4. Conclusions and Recommendations
The primary conclusion of the investigation is that the Agaura type gold
mineralization provided distinguishable IP/resistivity signatures. The correlation
between IP/resistivity and Cyril Knight Showing not as exemplary because of lack of
data; however, the correlation between IP/resistivity and Cyril Knight Showing is not
as exemplary because of lack of data; however, a signature would probably be
obtained by properly conducted survey (Jagodits, F.L,
March, 2014).
The IP/resistivity survey also detected two targets (Targets 4 and 7) where the
apparent IP responses are anomalous but correlated with low apparent resistivities. In
both cases the IP trends are associated with or in direct correlation with VLF-EM
conductors that may show conductive structures. Possible sources of the
IP/resistivity responses include non-magnetic sulphides and graphite.
51
It is recommended:
- the preparation of a new base map at a scale of 1:10 000, covering the expanded
claim block, showing claims, claim numbers and topographic details,
- incorporation of the base map of the present compilation and the compilation of
available exploration data covering the new claim block
- recover the drill hole locations at Agaura Showing,
- drill testing 0f the showing,
- establish a grid covering the original claims extending to the east to cover
possible extension; line direction: N - S; line interval:75 m; station interval: 25 m,
- ground magnetic total field/gradient survey, if possible with VLF-EM; station interval:
12.5 m,
- Induced Polarization/resistivity survey, initially using gradient array to locate the
anomalies, with subsequent detailing using dipole-dipole array,
- geological mapping of the original claims,
- prospecting of the Expanded Claim Block.
Preparation of solid colour and black contour magnetic map, with INPUT
anomalies, covering the claim block using the OGS INPUT/magnetometer survey,
and the above map with overlain with geology.

Discussion of the Results of the 2016 Spectral IP/Resistivity Survey
(Jagodits, F. L. 2016)
The four IP anomalous horizons discovered by the survey are sub-parallel and
confirm with the northeast trending geology. Based on the line to line correlation
of the apparent resistivity and chargeability data, above mentioned trends were
outlined. These are identified as Trends RIP-1A, RIP-1B, RIP-1C, RIP-1D RIP-2,
RIP-3, RIP-4 and RIP-5 and shown on the Interpretation Map (Figure 3).
The approximate surface expressions of the sources are indicated on the
Interpretation Map. The range of chargeabilities is given on the Interpretation
Maps as multiples of the background chargeability in the vicinity of the anomaly.
The numerical values are further discussed in Table I.
The major, prominent features are the centrally located RIP-1A and RIP-1B. It is
of outmost significance that Trend RIP-1A is the easterly continuation of an IP
trend of an earlier survey that covers the Agaura Showing (Jagodits, F.L., 2014, in
the Appendix). Hence, the anomalies of Trend RIP-1A are prime, first priority
drill targets.
The IP anomalies of RIP-1A are well defined; in fact, some are classic examples
of IP responses over vertical sources (L75E). The sources are shallow seated, and
associated with magnetic responses that may describe intermediate to basic
composition volcanics. The location of the sources at the eastern end of RIP-1A
are dubious, the line to line correlation not as clear as at western end. Subsidiary
Trend RIP-1D is the attempt for the separation of the sources.
Trend RP-1B is interpreted to be the faulted–off easterly extension of RIP-1A. At
the eastern of the trend, the IP and resistivity expressions become complex
describing a wider, multi-sourced anomalous horizon. Subsidiary trends RIP1-C
and RIP-2 are attempts to separate the sources. The eastern end of RIP-1B is
associated with a magnetic anomaly trend (Lines 600E to 750E) that may indicate
intermediate to basic composition volcanic rocks.
The 825 m long RIP-4 is characterized by high chargeabilities in conjunction with
low apparent resistivities. The anomalies are open to the south from L0 to L225E.
Magnetic expressions are absent. This formational source, on the whole, is
graphitic source. As it stands, there is no further interest in RIP-4.
RIP-5, in the northwest of the grid (Lines 0E to 375E) is similar to RIP-4, but not
as well developed. It is interpreted to be a part of another formational source. It is
of no further interest.
