Vassan Property Value Potential
The Vassan Property consists of 287 claims (approximately 16,299 hectares or 163 square
kilometres) and is located eight (8) kilometres due north of Val d’Or, Quebec. The property has
the potential to host both gold and lithium deposits. The property is easily accessed and lies in a
mining friendly jurisdiction that has well-established infrastructure. A prominent feature of the
Vassan Property is the Lacorne pluton and the associated pegmatite dykes, which are important
for lithium bearing intrusions and economic targets. In addition the Larder Lake-Cadillac fault
zone intersecting the southern Property is a host to gold bearing quartz veins.

Geology: Lacorne pluton emplacement and evolution
The Lacorne pluton is a member of the Archean Preissac-Lacorne batholith syn- and posttectonically emplaced in the Southern Volcanic Zone of the Abitibi greenstone belt, in the
Superior Province of the Canadian Shield ([1]). The batholith is bounded to the north by the
Manneville fault zone and to the south, by the Larder Lake-Cadillac fault zone and the eastern
extension the Destor-Porcupine fault zone as shown in Figure 2. The intrusion of the batholith
occurred along the La Pause anticline and into mafic and ultramafic lavas of the
Kinojevis (2718 Ma) and Malartic groups as well as biotite schist of the Kewagama Group ([1]).
A simplified map of the Preissac-Lacorne batholith is shown in Figure 3.
Figure 2. Major lithologies and faults of the Abitibi greenstone belt.
The Preissac-Lacorne batholith is inferred to have been emplaced during the waning stages of
continental collision, resulting in the development of the Abitibi greenstone belt ([1]). The
composite body of the batholith comprises of metaluminous gabbro, diorite, monzonite, and
granodirite, whereas the four plutons (see Figure 3) are monzogranitic ([4] and [5]). The basic
igneous rocks of the batholith are interpreted to have resulted from partial melting of the mantle
wedge within the subduction zone, whereas the monzongranties are inferred to be products of
partial melting of the (host) sedimentary rocks of the Pontiac Subprovince ([1] and [2]).
The intrusion is interpreted to have occurred in two stages; the first stage was marked by the
emplacement of syntectonic gabbro and granodiorite (2671-2675 Ma) and the second, posttectonic stage (2630-2655 Ma), was marked by the emplacement of monzogranite and
pegmatite ([2]).
The north-south oriented elliptical (plan view) Lacorne pluton, as described by Mulja et al. [1],
dominantly ranges from muscovite monzogranite at the centre, to two-mica monzogranite, and
biotite monzogranite at the contacts with the country rock. A succinct overview of the pluton
formation is provided by Lavery and Stone [4],

early side-wall crystallization produces marginal biotite monzogranite and more buoyant
crystal-layer melts; these ascend to the roof of the magma chamber;

fractional crystallization continues to form successive two-mica and muscovite
monzogranite layers and more differentiated melts;
fluid overpressure leads to expulsion from the chamber of pegmatite-forming volatile-rich
magma which results in the emplacement of beryl pegmatites in the overlying
monzogranite;
eventual contraction of the pluton (cooling) reactivates fractures in the country rock and
produces new fractures; these fractures are intruded with the more evolved melts which
gives rise to spodumene-beryl and spodumene pegmatites.

Spodumene Bearing Pegmatite Dykes: Overview
The spodumene pegmatites are of economic importance due to their bearing of lithium; in
accordance with the geological model and data obtained from diamond drilling these occur as:
(i) tabular dykes ranging from tens of centimetres to 8 m in width and up to hundreds of metres
in length, (ii) lenticular bodies up to 5 × 24 m in plan view, and (iii) dyke swarms particularly
along the margin of the pluton ([3]). The pegmatites associated with the Lacorne pluton are
zonally distributed and vary from beryl-bearing in and at the margins of the pluton, to beryl and
spodumene at the margins, and to spodumene-bearing pegmatites in the country rock ([1] and
[4]). This zoning of spodumene pegmatites in relation to the proximity of the dykes from the
parental pluton suggests that a mining programme within the country rock adjacent to the pluton
represents the greatest chance of success of intersecting economically viable lithium bearing
geobodies ([5]).
Additionally, as noted by Rowe [5], the pegmatites of economic interest possess a sharp contact
with the host rock, thereby increasing the effective scattering cross-section and lending itself to
diffraction-based seismo-acoustic methods with a high chance of success of outlining pegmatite
dykes.
Gold veins: geological setting
Gold-quartz vein fields in metamorphic mafic and ultramafic terranes, such as greenstone belts,
provide evidence for the involvement of large volumes of fluids during faulting and may be
products of seismic processes near the base of the seismogenic regime. In the Val d’Or district
of the Abitibi greenstone belt the quartz-tourmaline-carbonate veins form a vein field in the
hanging wall (Abitibi Subprovince) of a crustal-scale fault zone, the Larder Lake-Cadillac fault
zone, which was the main pathway for upward migration of the deeply generated fluids ([6]).
Three main phases of deformation have been documented in the area: an early phase of D1
folding has been recognized locally, especially in the western part of the area (see Figure 2). A
penetrative E-W subvertical foliation, containing a downdip elongation lineation, overprints such
folds and defines a second phase of deformation D2. D2 is largely responsible for the
dominantly E-W structural trend in the area and records significant N-S shortening across the
belt. A third increment of dextral transcurrent deformation was largely localized along the Larder
Lake-Cadillac fault zone, at the Subprovince boundary ([6]).
Structural relations indicate that third-order shear zones (see Figure 4), with which the majority
of gold-quartz veins are associated, formed during the late stages of the D2 shortening, prior to
Figure 4. Relationships between veins and shear zones in
the Val d'Or region. Modified after Robert et al. [6].
the D3 transcurrent deformation ([6]).
As noted by Robert et al. [6], the fault veins form ellipsoidal lenses 25-100 m long and 1-2 m
thick with moderate to steep dips. As in the case of pegmatite dykes, these geological features
are sufficiently large and differentiated from the adjacent rock to allow for a successful
diffraction-based seismic imaging campaign.
Value Impact on Vassan Property
The general geological and structural knowledge as discussed in the above text (see also
Figure 5) combined with geophysical data (Figure 6) allows for initial target area estimation.
These data provide a good first-look analysis which strongly indicates reason for preliminary
identification of strategic high value target propositions.
Synopsis
Gold Targets
The potential gold deposits would be hosted within zones of structural weakness, known as fault
zones and shear zones, similar to those of the nearby Val d’Or gold deposits. The majority of
the gold is directly associated with quartz-veins which occur in several rock types including
mafic volcanic, sedimentary and granitic rocks. The gold production from currently active
projects and past producers are highlighted in the following table:

Lithium Targets
The potential lithium deposits would occur within quartz-feldspar+/-spodumene pegmatite
dykes, which are hosted in the granitic rocks of the LaCorne Batholith and the mafic volcanic
and sedimentary rocks adjacent to this batholith. The best example of a lithium deposit in a
similar geological setting would be the Quebec Lithium deposit. This deposit has a NI43-101
compliant resource of:
Measured and Indicated Resources: 33.24Mt @ 1.19% Li2O
Inferred Resource: 13.76Mt @ 1.21% Li2O
Preliminary Targets of Interest
The following targets were selected from a preliminary review of the currently available public
data. These targets will be further refined as the data compilation and interpretation progresses
in the coming weeks (refer to Figures 5 and 6).
Target 1:
This lithium target occurs at the southern contact of the LaCorne Batholith and the mafic
volcanic rocks of the LaMotte-Vassan Formation. There is a pronounced magnetic highmagnetic low feature that defines an interpreted east-west trending structure.
Target 2:
This lithium target occurs at the southern contact of the LaCorne Batholith and the mafic
volcanic rocks of the LaMotte-Vassan Formation. There is a pronounced magnetic low feature
that occurs on the edge of an interpreted east-west trending structure.
Target 3:
This lithium target occurs at the southern contact of the LaCorne Batholith and the sedimentary
rocks of the Caste Formation. There are several isolated magnetic highs that appear similar to
the magnetic signature of the deposit on the Quebec Lithium property.
Target 4:
This lithium target occurs within the mafic volcanic rocks of the LaMotte-Vassan Formation near
the southern contact of the LaCorne Batholith. There is a pronounced magnetic high-magnetic
low feature that defines interpreted east-west trending structure.
Target 5:
This lithium target occurs within the mafic volcanic rocks of the LaMotte-Vassan Formation near
the southern contact of the LaCorne Batholith. There is a pronounced magnetic high-magnetic
low feature that defines interpreted east-west and northwest-southeast trending structures.
Target 6:
This gold target occurs within the mafic volcanic rocks of the LaMotte-Vassan Formation. There
are pronounced magnetic high-magnetic low features that define several interpreted east-west
and northwest-southeast trending structures.
Target 7:
This lithium target occurs at the northern contact of the LaCorne Batholith with sedimentary
rocks and occurs 3 kilometers southeast of the Quebec Lithium deposit. There is a pronounced
magnetic high-magnetic low feature that defines the same northwest-southeast trending
structure that hosts the Quebec Lithium deposit
