1.0 SUMMARY
Ronacher McKenzie Geoscience was commissioned to review eight polished thin sections from
International Montoro Resources Inc. (“Montoro”) Pecors Cu-Ni-PGE project near Elliot Lake, Ontario. The
samples were from drill hole P-22 The petrography indicated that:
 the samples were from various distinct rock types although they are from the same drill hole (P-22)
 although most samples were originally likely gabbros, the mafic components (pyroxenes) were
invariably altered to chlorite (+epidote); therefore, they the rocks are interpreted to be metagabbros
 sample P-22-823 was distinct from all others and is not interpreted to be a metagabbro
 sulfides are rare in some samples but occur in veins, veinlets and disseminations in some samples
 the dominant sulfides are pyrite, pyrrhotite and chalcopyrite
 relict magnetite occurs in some samples
 olivine was not observed in any sample
 zircon was not observed in any sample
2.0 INTRODUCTION
Don Hawke of International Montoro Resources Inc. (“Montoro”) commissioned Elisabeth Ronacher of
Ronacher McKenzie Geoscience to complete transmitted and reflected light petrography on eight polished
thin sections from drill hole P-22 from Montoro’s Pecors Ni-Cu project near Elliot Lake, Ontario.
Drill core samples were provided to Ronacher McKenzie Geoscience on April 22, 2015. The core samples
were described and photographed before they were submitted to the thin section preparation laboratory at
Laurentian University, Sudbury, Ontario (“Janwill Petrographic”, Willard Desjardin). The list of samples is
shown in Table 2-1. Photos of the drill core samples are provided in Appendix 2.

2.1 Scope
The scope of the petrography was to:
1. describe the silicate minerals and their relationships
a. A distinction between ortho- and clinopyroxene, if present, was to be attempted
b. Presence of olivine was to be particularly noted
c. Presence of zircon was to be noted
2. describe the opaque assemblages and their relationships to each other and to the silicate minerals
3. estimate modal abundances of silicate and opaque minerals
4. provide at least one photomicrograph of each section identifying the minerals present
In addition, rock names were assigned to each specimen based on the petrographic examination.
2.2 Glossary
The following mineral abbreviations were used in this report:
Amph = amphibole
Bi= biotite
Chl = chlorite
Cpy = chalcopyrite
Epi = epidote
Fsp = feldspar
Pent = pentlandite
Plag = plagioclase
Po = pyrrhotite
Py = pyrite
Qtz = quartz

3.1.2 Description
Plagioclase is the dominant mineral in this sample (Figure 3-1, Figure 3-2). It occurs as up to 5 mm long
laths and also as very fine-grade crystals in the matrix. Chlorite is the second most dominant mineral altering
plagioclase. Epidote occurs with chlorite. Epidote-chlorite veinlets cut the rock.
Trace disseminated chalcopyrite and pyrite were observed in the chlorite matrix and in cracks in epidote.
One sulfide grain appeared to be hosted entirely by epidote. Other opaque minerals are considered to be
iron oxides.
Zircon or olivine were not observed in this thin section.
3.1.3 Interpretation
This rock was originally a gabbro but was altered by chlorite (+carbonate+epidote). Sulfides are rare but
where present and occur in the chlorite matrix. Based on this description the rock is considered to be a
metagabbro. Amphibole (hornblende) was not observed in this section.

3.2.2 Description
Large amphibole crystals (up to 2 mm; Figure 3-4, Figure 3-5) and plagioclase (also up to 2 mm long; Figure
3-6, Figure 3-7) occur in a matrix of finer-grained plagioclase, amphibole and chlorite. Some amphiboles
are light to bottle green (sodic amphibole?). Amphibole and plagioclase are partly replaced by chlorite.
Minor chalcopyrite and pyrite occur in amphibole (Figure 3-8, Figure 3-9), disseminated in the matrix and
as thin veinlets. Patches of mosaic quartz were also observed. Rutile was also observed in this sample.
This rock is interpreted to be an amphibolite. An interpretation of the origin of the sulfides should take into
account that some sulfides are enclosed in amphibole and others are spatially associated with chlorite.
Whether the sulfides were introduced during the metamorphic/hydrothermal event or were remobilized
during this event should be determined within a broader geological context.

3.4.2 Description
Medium-grained plagioclase laths (up to 2 mm) with interstitial chlorite occur in this sample (Figure 3-13,
Figure 3-14). A quartz-epidote-chalcopyrite vein crosscuts the thin section. Chalcopyrite is completely
surrounded by quartz and epidote. Sulfides also occur interstitially in chlorite and fully enclosed in epidote.
The mafic phases of this rock are replaced by chlorite. It is interpreted to be a metagabbro. Sulfides are
dominantly associated with chlorite; they are therefore interpreted to be either remobilized primary sulfides
or to have been introduced during the hydrothermal event during which chlorite formed.

3.5.2 Description
The rock consists dominantly of large (up to 1 mm) plagioclase crystals with interstitial chlorite and minor
epidote (Figure 3-15). A quartz-chlorite-sulfide vein and a 1 mm-wide sulfide vein cross-cut the rock (Figure
3-16). An epidote halo exists along the edges of the quartz-chlorite-sulfide vein. The dominant sulfide is
pyrite with minor chalcopyrite and trace pyrrhotite in pyrite. Larger pyrite occurs in the veinlets whereas
chalcopyrite occurs dominantly as fine-grained disseminations in chlorite-epidote-quartz.
The mafic components in this rock are replaced by chlorite; the rock is interpreted to be a metagabbro. The
association of sulfides with quartz suggests an introduction or remobilization of the sulfides after cooling of
the gabbro.

3.6.2 Description
This rock consists of fine-grained quartz with biotite and chlorite and larger (up to 0.5 mm) epidote. The
epidote appears to have sulfide inclusion (pyrite, chalcopyrite). One larger (2 mm wide) cluster of sulfides
(pyrite±chalcopyrite) is surrounded by chlorite and biotite.
This rock consists of chlorite, biotite, quartz and feldspar. Quartz is very fine-grained (mosaic quartz) as is
typical of metamorphosed sedimentary rocks, however, white mica was not observed. Classification of this
rock requires knowledge of the geological context and whether this particular thin section is representative
of the entire sample. Zircon was not observed in this section.

3.7.2 Description
Very coarse-grained (up to 2 mm) and altered feldspar and amphibole occur in a fine-grained matrix. The
matrix consists dominantly of chlorite and epidote. Amphibole and feldspar are partly replaced by chlorite.
Pyrrhotite, pyrite and chalcopyrite are disseminated in the matrix; however, locally they also appear to be
hosted and enclosed by amphibole. Flame-like exsolutions in pyrrhotite are interpreted to be pentlandite.
This rock is interpreted to be amphibolite. However, amphibole crystals are strongly resorbed by chlorite.
Sulfides occur both disseminated in the alteration minerals and apparently in amphibole. Zircon or olivine
were not observed in this section.
Relict amphibole crystals resorbed by chlorite.

3.8.2 Description
Large (up to 1.5 mm) amphiboles dominate the thin section (Figure 3-24); the amphibole appears to have
sulfide inclusions. Sulfides also occur as disseminations and in veinlets. A part of the thin section consists
of fine-grained chlorite-amphibole-feldspar. Two prominent epidote-carbonate±sulfide veinlets cut the rock
(Figure 3-25, Figure 3-26). The sulfides are pyrite, pyrrhotite and chalcopyrite (Figure 3-26).
The rock is interpreted to be an amphibolite. Late chlorite veins cut the amphibolite and some amphiboles
are altered by chlorite. The rock is not homogeneous with patches of fine-grained and coarser-grained
minerals. Sulfides filling interstitial voids may be primary.
Zircon, olivine or pyroxene could not be identified in this thin section.
Large crystals with high interference colors are amphibole surrounded by chlorite.

4.0 CONCLUSIONS
The samples from drill hole P-22 are metamorphosed and most of them are moderately altered (e.g.,
resorbed feldspar and completely replaced mafic phases: chlorite and amphibole after pyroxene). Sulfides,
dominantly pyrrhotite, chalcopyrite and pyrite, are spatially associated with chlorite, epidote and amphibole.
The spatial association of sulfides with these secondary minerals may indicate a remobilization of primary
sulfides during metamorphism or introduction of the sulfides during the hydrothermal/alteration event.
All samples with the exception of P-22-823 are interpreted to be of gabbroic origin. P-22-823 contains ~20%
quartz and cannot be called a gabbro. Classification of this rock requires knowledge of the geological
context and whether the sample is representative.

May 25, 2015 Page | 33
Detailed interpretation of the petrogenesis would have to be completed with knowledge of the entire drill
log and in a broader geological context.
