Magna Terra Identifies Multiple Priority
Exploraton Targets at the Rocky Brook Project
in the Bathurst Mining Camp, New Brunswick;
Expands Land Package Along Key Trends
Toronto, Ontario--(Newsfile Corp. - October 27, 2025) -
Magna Terra Minerals Inc
.
(TSXV: MTT)
(the
"
Company
" or "
Magna Terra
") is pleased to announce that it has identified five high priority targets with
a cumulative strike length of a minimum of 30 kilometres at it's Rocky Brook Project ("Rocky Brook" or
the "Project"), located in the prolific Bathurst Mining Camp ("BMC") of northern New Brunswick
(Figure
1)
. These new targets were identified via a combination review and targeting analysis of regional
airborne geophysical data sets and a comprehensive machine learning study completed utilizing
Windfall Geotek Corp.'s ("Windfall Geotek") AI System.
Based on the results of the combined work to date the Company has acquired an additional 7 claims via
staking, totalling 305 hectares in the Restigouche and Orvan Brook Prospect areas.
"We are excited to incorporate the results of both the Windfall Geotek and Mira Geoscience's analysis
of the regional project data in our project exploration planning. The combination of machine learning
and traditional approaches to analysing historic data from the project have generated a number of
high priority geological trends that support and enhance the discovery potential on the Rocky Brook
Project. This targeting exercise will also help inform our exploration approach on each of these target
areas. As we continue to compile additional historic geological, geochemical, and geophysical data
we will incorporate the results into further refining and prioritizing exploration targets on this extensive
property."
~ Lew Lawrick, President and CEO, Magna Terra Minerals Inc.
Magna Terra would like to acknowledge and thank the Province of New Brunswick for partial financial
assistance granted for work on the Rocky Brook Project under the New Brunswick Junior Mining
Assistance Program ("NBJMAP").
Exploration Target Generation
Windfall Geotek was engaged to complete this data driven, targeting exercise based on their
experience within the BMC, and utilizing their proprietary machine learning algorithm, encompassing a
comprehensive training dataset. This work resulted in predictive models for copper and zinc
mineralization on the Rocky Brook Project based on training data and similar geophysical, geological
and geochemical parameters to known massive sulphide deposits in the region. In addition, the
Company contracted Mira Geoscience Ltd. ("Mira Geoscience") to complete an analysis and targeting
exercise by reviewing previous regional airborne electromagnetic (2000 MegaTEM) and gravity (2009
Bell Geospace and 2013 HeliFALCON) datasets that cover the majority of the BMC.
This comprehensive targeting exercise generated
five priority targets totalling 30 kms of strike
, that
include the following:
Restigouche Trend
- A
4.2-kilometre
-long zone of elevated Cu and Zn mineralization that includes the
C-4 and C-5 footwall zones to the past-producing Restigouche massive sulphide deposit. The lateral
extents to the east and west of the C-4 and C-5 zones have similar geophysical (relatively high
conductance and gravity) and geochemical properties to known massive sulphide deposits in the BMC,
and indicates that this area has strong potential to host additional massive sulphides or associated
footwall sulphide stringer systems, similar to Canadian Copper Inc's Murray Brook Deposit located 9
kms to the east.
Mount Ganong Trend
- A
4.8-kilometre
-long trend of predictive Cu-Zn mineralization with high
conductance and distinct associated gravity anomalies, centred 10 kms to the southeast of the
Restigouche Deposit. The target sits near the contact between Tetagouche Group felsic volcanics to the
east and Miramichi Group sediments to the west.
Boudreau Brook
-
Fossil Hill Trend
- The Boudreau Brook Trend includes known occurrences at the
Boudreau Brook and Fossil Hill targets, where previous rock grab sampling* has returned 3% Cu and
16.65% Cu and 0.64% Co, respectively as well as highlighting several other coincident geochemical and
geophysical (gravity and EM) targets over a
15-kilometre
cumulative strike length.
Orvan Brook Trend
- The Orvan Brook Trend comprises
6 kilometres
in three zones that show
combined anomalous soil and rock geochemistry along with coincident gravity and conductivity highs.
Cook Savoie Trend
- The Cook Savoie trend is a
1.8-kilometre
-long predictive Cu-Zn target that has
coincident airborne conductivity and gravity anomalies that sits near the contact between Tetagouche
Group felsic volcanics to the south and Miramichi Group sediments to the north.

Rocky Brook Project Highlights
The Project covers a 30-kilometre extent of the Rocky Brook-Millstream Fault system as well as a
40-kilometre extent of favourable California Lake Group felsic volcanic and sedimentary rocks that
are host to the nearby Restigouche, Murray Brook, and Caribou Deposits;
Identification of the Boudreau Brook Trend - a 15 kilometre trend of coincident geochemical and
geophysical anomalies and historical prospects;
Strategically positioned along strike from Kinross-Puma's Lynx Zone gold discovery and adjacent
to the past-producing Caribou Mine and Murray Brook base metal deposits;
Recent discovery in 2023 of high-grade gold assays from grab samples* assaying up to 5.23 g/t
Au over a 400 m area at Fournier Lake;
Previous work at the Fossil Hill Zone has discovered high-grade copper-cobalt mineralization with
grab samples* assaying up to 16.65% Cu and 0.64% Co;
Previous work at the Boudreau Brook prospect has discovered copper mineralization assaying up
to 3% Cu;
The property covers the Restigouche C-4 and C-5 footwall Cu-rich "feeder" zones where previous
historical drilling at the C-4 zone and in hole C-4 that intersected 4.36 m grading 0.2% Cu, 1.6%
Pb and 6.74% Zn (from 17.3 to 21.6 m). The best intersection in the C-5 area was reported in hole
C-5 that intersected 2.06% Cu and 0.57% Zn over 4.5 m (from 51.9 to 56.4 m);
Located in the prolific Bathurst Mining Camp within the top-tier mining jurisdiction of New
Brunswick; and
Year-round accessibility with road access to the majority of the property.
The Rocky Brook Project
The Rocky Brook Project comprises 18,999 hectares in 65 mineral claims making the Company one of
the single largest strategic landholders in this historic mining camp (
Figure 1
). The Rocky Brook Project
is located adjacent to and along strike from the Williams Brook Project, owned by Kinross Gold
Corporation ("Kinross") and Puma Exploration Inc. ("Puma"), where a zone of high-grade gold
mineralization was discovered over broad widths including drill intervals up to 5.55 g/t Au over 50.15 m
(refer to Puma's news release dated September 15, 2021). The Project is located adjacent to a 30-
kilometre-long section of the Rocky Brook-Millstream fault and associated McIntyre and Ramsay Brook
faults; an important structural zone controlling gold mineralization within the region. The Project also
covers volcanic and sedimentary rocks that show strong potential to host polymetallic Cu-Co-Pb-Zn-Au-
Ag mineralization, adjacent to the past-producing Caribou Mine and the Murray Brook Deposit; the
largest undeveloped VMS project in New Brunswick owned by Canadian Copper Inc. (
Figure 1
).
The Bathurst Mining Camp
The Bathurst Mining Camp is one of the world's oldest base metal (lead, zinc, copper, gold and silver)
mining districts hosting one of Canada's largest volcanogenic massive sulphide (VMS) deposits, with
the past-producing Brunswick No. 12 Mine having operated for 49 years. The BMC is host to over 46
mineral deposits, several of which have been mined, including the Brunswick No. 6, Heath Steele,
Wedge, Stratmat, Half Mile Lake, Caribou and Murray Brook. A total of 136,643,367 tonnes of ore
grading 3.44% Pb, 8.74% Zn, 0.37% Cu, and 102.2 g/t Ag were mined from the BMC (McCutcheon and
Walker, 2020**).
