Exploration Crew to Commence Surface Sampling and
Mapping Program at Bohier & Eastmain Léran, Quebec
HIGHLIGHTS
Recently completed airborne LiDAR survey at Bohier shows several
outcropping areas with LCT pegmatite characteristics.
Detailed analysis of the high-resolution air photos confirmed the area
is underexplored with less than 5% of the visible outcrop previously
mapped or sampled.
Helicopter supported lithium exploration/prospecting program to
commence at Bohier and Eastmain Léran Projects now access is
allowed following Quebec Ministry wildfire safety measures.
The program aims to identify outcropping, collect grab samples and
carry out detailed mapping along the greenstone belt targeting
Lithium, Caesium, Tantalum (LCT) pegmatites from the Wahemen
granite formations.
Eastmain Léran initial drilling results received from the spring 2023
exploration program.
Mont Royal Resources Limited (“Mont Royal”, the “Company”) (ASX:MRZ) is
pleased to announce that a two phase exploration program will commence at
the Northern Lights Projects in the Upper Eastmain Greenstone Belt located in
Quebec, Canada.

Mont Royal Executive Director, Pete Ruse, commented: “The Company is encouraged by the detailed
analysis of the data sourced from the LIDAR survey completed in May 2023, which will assist greatly in
expediting the field prospection program. Coupled with anomalous soil samples in the down ice direction
and within the Greenstone Belt, the historical data compilation has developed numerous targets over a
10km strike length that have never been explored for lithium. We expect to return to the field in the very
near term as the James Bay region re-opens for exploration, as service providers (helicopter, contractors)
are being released back to the mining/exploration sector after carrying out firefighting efforts throughout
June and July.”
Completed LiDAR and Orthophoto Survey
LiDAR has many uses, and is particularly valuable for showing subtle variations in relief or elevation
on the ground. The LiDAR Survey at Bohier (Fig. 2) was completed by Mosaic 3D during late May
2023 covering a 91.6 km2 area. A density of 6-8 pts/m2 enabled the production of a digital elevation
model (DEM) with a 1m/pixel resolution and a vertical accuracy between 5 and 30 cm depending
on the substrate (e.g., more precise for hard surface and less precise for vegetated areas).
Image: Geological map overlaid with results from LiDAR Survey analysis at Bohier Project
The DEM is accompanied by a series of 131 orthophoto with a resolution of 8 cm/pixel. These
parameters enable the recognition of light-coloured outcrops with a positive relief (Fig. 3), which is
typical of white and more resistant pegmatites. Close examination of the photo suggests the
2
presence of pegmatite dykes frequent along more than 10 km in the volcanic and sedimentary
rocks. This interpretation will help the field crew to focus on the most prospective areas facilitating
accuracy and efficiency when working in the field in the near term.
Summer 2023 Surface Exploration Program
The summer 2023 surface exploration program will include prospecting, rock sampling, and
geological mapping, using the data that was delivered from the property-scale LiDAR and
orthophoto survey. This program will be led by the IOS Services Geoscientifiques technical team.
The clear objective of the surface program at Bohier is to evaluate the dolent mafic volcanics, the
same geological package that hosts neighbouring Benz Mining’s Ruby Hill pegmatites, and the
adjacent Bohier metasedimentary rocks. The geological mapping and rock sampling will be used to
delineate drill targets and to commence an immediate drilling program to follow up observations
and data from the field.
Following the work at Bohier, the field crew will proceed to a mapping and sampling program at the
Eastmain Léran Project (Fig 4), which is a favourable lithium target due to the proximity, to the
north, of the Wahemen granite which has the chemistry and mineralogy of a LCT pegmatite
parental granite (Talla Takam and Beauchamp, 2016). The pegmatites are unlikely to be found in
the granite itself but in the mafic volcanics a few kilometres from the greenstone – granite contact.
The objective is to find and sample granite and pegmatites outcrops and use their chemistry, for
vectoring. Areas with greater potential have already been identified by the presence of tantalum
minerals in a 2017 till survey and the presence of spodumene-bearing boulder in a 2016
government-led mapping program.

Eastmain Léran Drilling Program
In April 2023, the Company completed diamond drilling program of 4 holes targeting potential
copper & gold extensions to historical exploration in the 1950’s and 1970’s. The program consisted
of approximately 1,000m of drilling.
Although the intersected copper grades are underwhelming, the targeted volcanoclastic rocks are
clearly anomalous. The sulphides and grades distribution show an increase in copper content at
depth toward the ESE. To the SW, hole ALT-23-06 is barren but a soil anomaly indicates that either
the hole went below a shallow copper zone or that there is an inflexion in the mineralized zone and
that it is located south of the hole. The mineralization remains open at depth and further analysis
may open up potential for a second phase of drilling coupled with borehole EM to confirm the
geometry of the copper anomalous zone, and identify potential high-grade zones.
Table below summaries the result received in-excess of a 0.4% Cu cut off.

Update on fires affecting regional Quebec
During June, the James Bay region of Quebec was subject to an emergency fire evacuation order
from the Ministry of Natural Resources and Forests. Due to the high-risk fire conditions during
June in the region, along with active fires elsewhere in the province, the ministry mandated that all
activities in the regions’ forests cease immediately, including mineral exploration, and that all
personnel be evacuated. Therefore, following the notice, the Company temporarily suspended its
exploration activities at Bohier and Eastmain Léran and evacuated its field crews without incident.
Pleasingly the Company was able to successfully complete its LiDAR survey ahead of this event,
with approximately four days of fieldwork before the evacuation. The Company is now set to return
to the fieldwork as soon as the key service providers return to normal business following the
firefighting effort.

The Company looks forward to embarking on its summer 2023 exploration program and will keep
shareholders informed with updates as soon as they become available.

If the exclusion of this information

the Competent Person should

In reporting Exploration Results,
weighting averaging techniques,
maximum and/or minimum grade
truncations (eg cutting of high
grades) and cut-off grades are
usually Material and should be
stated.
Where aggregate intercepts
incorporate short lengths of highgrade results and longer lengths of
low-grade results, the procedure
used for such aggregation should
be stated and some typical
examples of such aggregations
should be shown in detail.
The assumptions used for any
reporting of metal equivalent
values should be clearly stated.
These relationships are
particularly important in the
reporting of Exploration Results.
If the geometry of the
mineralisation with respect to the
drill hole angle is known, its nature
should be reported.
If it is not known and only the
down hole lengths are reported,
there should be a clear statement
to this effect (eg ‘down hole

Appropriate maps and sections
