Magna Terra Provides Updated Mineral Resource ON the Thor Deposit, Great Northern - Viking Project, Newfoundland
MAGNA TERRA PROVIDES UPDATED MINERAL RESOURCE ON THE THOR
DEPOSIT, GREAT NORTHERN - VIKING PROJECT, NEWFOUNDLAND
Toronto, Ontario – November 6, 2023 – Magna Terra Minerals Inc. (the “Company” or “Magna Terra”) (TSX-V:
MTT) is pleased to announce that it has completed a n Updated Mineral Resource Estimate on the Thor Deposit
(“Thor” or the “Deposit”) on its 100% owned Great Northern - Viking Project (“Viking” or the “Project"), located in
western Newfoundland. The Great Northern - Viking Project area is a proven gold environment with existing Mineral
Resources and numerous untested gold trends over a cumulative 30+ kilometre strike with the potential to host multi-
million-ounce gold deposits (Figure 1).
“We are continuing to advance our flagship Great Northern - Viking Project despite the difficult current market
environment for gold explorers. The Mineral Resource Update modernizes the Thor Deposit Mineral Resource in
keeping with the latest CIM Guidelines as well as facilitating a full remodelling of the Deposit geometry and grade
distribution/trends. We will use this update d resource and geological work to target zones for potential expansion
where the deposit is open in all directions; to the south, north, and down-dip. In addition to the immediate opportunity
for expansion at Thor, there remains several poorly-tested and untested zones of gold mineralization in the immediate
vicinity of the Thor Deposit, including the Kramer, Viking and Viking North Trends; part of the more than 30+
cumulative kilometres of strike potential that have been identified to date on the Great Northern - Viking Project.
What stands out significantly about our Great Northern - Viking Project area is that the known gold endowment,
along with the impressive number and scale of high priority gold targets, underscores the potential of the Project to
host multiple large gold systems.”
~ Lew Lawrick, President and CEO, Magna Terra Minerals Inc.
Mineral Resource Update
The Company contracted Mercator Geological Services Limited to complete an Updated Mineral Resource Estimate.
The Updated Mineral Resource Estimate was completed in order to include additional drilling completed in 2016 that
was not included in prior assessments of the Deposit and also to bring the historical estimate into accordance with the
CIM MRMR Best Practice Guidelines that were issued in November 2019 (“CIM MRMR Guidelines”). The Updated
Mineral Resource is based on verified results of 162 diamond drill holes (23,775 m), including 10 drill holes (575 m)
completed in 2008, 35 drill holes (3,613 m) completed in 2009, 59 drill holes (9,735 m) completed in 2010, 25 drill
holes (4,698 m) completed in 2011 by Northern Abitibi Mining Corp. (now CANEX Metals Inc.), and 33 drill holes
(5,154 m) completed in 2016 by Anaconda Mining Inc (now Signal Gold Inc.).
The Updated Mineral Resource Estimate for the Thor Deposit comprises open- pit constrained Indicated Mineral
Resources of 817,000 tonnes at an average grade of 1.70 g/t gold for 45,000 ounces and open-pit constrained Inferred
Mineral Resources of 44,000 tonnes at an average grade of 1.27 g/t gold for 1,800 ounces at a cut -off grade of 0.46
g/t gold. The Thor Deposit also includes underground constrained Indicated Mineral Resources of 62,000 tonnes at an
average grade of 2.98 g/t gold containing 5,900 ounces and underground constrained Inferred Mineral Resources of
23,000 tonnes at an average grade of 3.31 g/t gold containing 2,400 ounces at a cut -off grade of 2.14 g/t gold (Table
1; Figures 2 and 3). The Effective Date of the Mineral Resource Estimate is October 24, 2023.

Notes:
1) The QP for the Mineral Resource statement is Mr. Matthew Harrington, P. Geo who is an employee of Mercator
Geological Services Limited.
2) Mineral Resources were prepared in accordance with the CIM Definition Standards (May 2014) and the CIM
MRMR Best Practice Guidelines (November 2019).
3) Open Pit Constrained Mineral Resources occur within an optimized pit shell with average pit slope angles of
45⁰ and a 5.5:1 strip ratio (waste: mineralized material).
4) Pit optimization parameters include pricing of US$1,850/oz Au (0.769 US$ to CDN$ exchange rate), mining
at CDN$4.5/t, combined processing, G&A, and trucking (1,250 t/d process rate) of CDN $33.85/t processed,
and an overall gold recovery of 96%.
5) Open Pit Constrained Mineral Resources are reported at a cut -off grade of 0.46 g/t gold within the optimized
pit shell.
6) Underground Constrained Mineral Resources are reported at a cut -off grade of 2.14 g/t gold based on total
operating costs of CDN$97.50/t processed.
7) Mineral Resources were estimated using inverse distance squared methods applied to 1.5 m capped downhole
assay composites. Prior to compositing, assays values were capped at a grade equivalent to 30.71 g/t/m gold
within the Thor Vein domain and at a grade equivalent to 12.5 g/t/m gold within all other mineralized domains.
Model block size is 3 m X by 6 m Y by 6 m Z.
8) An average bulk density of 2.7 g/cm3 was applied for Mineral Resources and waste material.
9) Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation,
sociopolitical, marketing, or other relevant issues.
10) Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.
11) Figures may not sum due to rounding.

Change Relative to the Historical Estimate
A Mineral Resource Estimate that is now historical in nature was prepared by Giroux Consultants Ltd. on behalf of
Anaconda Mining Inc, now Signal Gold Inc., with an effective date of August 29, 2016. A Q ualified Person has not
done sufficient work to classify th is historical estimate as current Mineral Resources. The historical estimate is
considered relevant as it demonstrates the three-dimensional continuity of the Deposit. Magna Terra is not treating the
historical estimate as current Mineral Resources and it is superseded by the Update d Mineral Resource presented in
this press release.
Results of the 2016 Thor Deposit historical estimate are 937,000 tonnes Indicated with an average grade of 2.09 g/t
gold and 350,000 tonnes Inferred with an average grade of 1.79 g/t gold. The historical estimate was based on a three-
dimension block model with Ordinary and Indicator Kriging grade interpolation and resources were reported at gold
cut-off of 1.00 g/t. Interpreted mineralized wireframes and capped downhole assay composites were used to constrain
grade interpolations.
The combined new Open Pit - Underground Mineral Resource Estimate represents a 6% decrease in tonnes, a 14%
decrease in grade and a 20% decrease in contained ounces for Indicated Mineral Resources and an 81% decrease in
tonnes, 10% increase in grade and 79% decrease in contained ounces for Inferred Mineral Resources compared to the
2016 historical estimate. The decreased Mineral Resource tonnes, grade and contained ounces are predominantly
related to the application of Reasonable Prospects for Eventual Economic Extraction factors for open -pit and
underground Mineral Resources in accordance with the CIM MRMR Guidelines. Additional changes are related to
remodelling of mineralized wireframes and changes in reporting cut -off grade due to adjustments in gold selling and
mining/production costs since the 2016 historical estimate.
About the Viking and Great Northern Projects
The Viking and Great Northern Projects are comprised of two separate claim blocks totalling 13,775 hectares, which
are located near the communities of Sops Arm, Pollard’s Point, and Jackson’s Arm, Newfoundland and Labrador.
The Projects are centered along a 30 -kilometre section of the Doucers Valley Fault, a significant geological control
on, and host to, several gold deposits and untested prospects, including the Rattling Brook and Thor Deposits plus the
Incinerator, Furnace, Jacksons Arm, Viking, Kramer, Viking North, and Little Davis Pond mineralized trends. This
proven gold environment with existing Mineral Resources and numerous untested gold trends occurs over a
cumulative 30+ kilometre strike length. Gold mineralization is hosted within a variety of rock types that include
Precambrian or Ordovician granites as well as younger volcanic and sedimentary rocks, typically along splays off the
Doucers Valley Fault. This is a similar geological/structural environment to Marathon Gold Corporation’s Valentine
Gold Project. Alteration consists of mesothermal style quartz ± iron carbonate ± sulfide veins and stockworks with 2
to 5% total sulfides consisting of pyrite, galena, chalcopyrite, or sphalerite. These mineralized veins locally show trace
amounts of visible gold.
The Viking and Great Northern Projects are host to significant Current Mineral Resources, including:
• An Inferred Mineral Resource Estimate of 5,460,000 tonnes at an average grade of 1.45 g/t gold containing
255,000 contained ounces at a cut-off grade of 1.0 g/t gold at the Rattling Brook Deposit; and
• An updated open-pit constrained Indicated Mineral Resource Estimate of 817,000 tonnes at an average grade
of 1.70 g/t gold for 4 5,000 ounces and open-pit constrained Inferred Mineral Resources of 44,000 tonnes at
an average grade of 1.27 g/t gold for 1,800 ounces at a cut-off grade of 0.46 g/t gold at the Thor Deposit. The
Thor Deposit also includes underground constrained Indicated Mineral Resources of 62,000 tonnes at an
average grade of 2.98 g/t gold, containing 5,900 ounces, and underground constrained Inferred Mineral
Resources of 23,000 tonnes at an average grade of 3.31 g/t gold, containing 2,400 ounces at a cut-off grade
of 2.14 g/t gold.
Several drill targets and specific opportunities for mineral resource expansion and discovery have been identified by
the Company based on recent field programs and a comprehensive review of historic al and current exploration data.
This work, in conjunction with that of previous operators on the Property, has identified the importance of fault control
on gold mineralization. These major target areas for near-term drill testing are:
• The Apsy Zone – Existing Mineral Resource area with potential for minimum 800 metre extension.
• Incinerator Trend – 1.8-kilometre-long gold-bearing east-west fault only tested by four historical drill holes
that intersected gold mineralization: 2.32 g/t gold over 4.1 metres (drill hole RB-41 from 33.1 m downhole);
1.06 g/t gold over 15.6 metres (drill hole RB-39 from 66.8 m downhole); 1.00 g/t gold over 9.7 metres (drill
hole RB -37 from 32.1 m downhole); and 1.78 g/t gold over 4.0 metres (drill hole RB -35 from 47.2 m
downhole).
• Furnace Trend – 1.7-kilometre long trend with rock grab samples** assaying up to 5.60 g/t gold along east-
west fault zone.
• Kramer Trend – 1.5-kilometre long northeast striking zone of gold mineralization centred on the contact
between granites and quartzites. Highlight assays from previous drill holes KR-10-07 and KR-10-08 include
1.12 g/t gold over 20.05 metres ( from 53.5 m downhole) and 1.50 g/t gold over 14.4 metres (from 66.85 m
downhole), respectively.
• Viking Trend – 6.4 kilometre long by up to 40-metre wide deformation and alteration zone with gold grades
of 0.45 g/t gold over 20.0 metres in drill hole VK -16-154 (from 48.0 m downhole), as well as local high
grades as indicated by 7.43 g/t gold over 1.0 metre in drill hole VK-16-155 (from 36.0 m downhole).
• Viking North Trend – 8-kilometre long east-west striking fault zone, sub-parallel to the Viking Trend, that
is host to gold mineralized rocks and soils from reconnaissance sampling assaying up to 2.12 g/t gold and
380 ppb gold, respectively.
• Jacksons Arm Trend – 2.4-kilometre-long gold zone defined by numerous gold bearing rock and soil
samples and from drilling in late 2020.
**Grab samples are selected samples and are not necessarily indicative of mineralization that may be hosted on the property.
