Magna Terra Expands the Rocky Brook Project, New Brunswick

Corporate Updates

Magna Terra Expands the Rocky Brook

Project, New Brunswick

Toronto, Ontario--(Newsfile Corp. - May 27, 2026) -

Magna Terra Minerals Inc

.

(TSXV: MTT)

(the

"

Company

" or "

Magna Terra

") is pleased to announce that it has expanded the footprint of the Rocky

Brook Project ("Rocky Brook" or the "Project"), located in the prolific Bathurst Mining Camp ("BMC") of

northern New Brunswick

(Figure 1)

. 7 claims totalling 5,770 hectares were strategically acquired via

staking, covering known mineralized trends and geochemical anomalies.

The acquired claims include:

2 large claims (4,080 ha) northeast of the Oxford Property that cover recently released stream

sediment anomalies showing elevated gold, silver, and copper values;

2 claims (500 ha) located within the Fournier Lake Gold Property;

2 claims (895 ha) located immediately east of the Mount Ganong Trend on the Restigouche

Property covering an area underlain by Tetagouche Group felsic volcanic rocks; and

1 claim (295 ha) located within the eastern end of the Boudreau Brook – Fossil Hill Property

covering the McIntyre VMS prospect.

"These additional property acquisitions continue our strategy of adding prospective ground, further

expanding our district-scale Rocky Brook Project, which now totals 36,533 hectares. The staking of

these claims increases our footprint in an emerging gold district along the Rocky Brook – Millstream

Fault, and associated splays at our Oxford and Fournier Lake Properties. As well, we continue to add

strategic claims enhancing our land position within the well-established base metal VMS belt as we

participate in the revival of the historic Bathurst Mining Camp. The addition of these new claims

further solidifies our large exploration land holdings in the heart of an established mining camp that is

experiencing a renewal, with numerous companies ramping up exploration activity within the greater

BMC. We continue to execute on our strategy of acquiring early-stage precious and critical metal

projects that offer good value and discovery upside for our shareholders, and this highlights our

conviction that New Brunswick and Atlantic Canada remain under-explored, presenting a compelling

opportunity for exploration and discovery. We look forward to updating shareholders on our plans for

our spring/summer field programs in the coming weeks."

Rocky Brook Project Highlights

VMS Highlights

The Project covers a 40-kilometre extent of favourable California Lake felsic volcanic and

sedimentary rocks that are host to the nearby Restigouche, Murray Brook, and Caribou Deposits;

Identification of the Boudreau Brook-Fossil Hill Trend – a 15-kilometre trend of coincident

geochemical and geophysical anomalies and historical prospects;

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 zone 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 premier mining jurisdiction of New

Brunswick; and

Year-round accessibility with road access to the majority of the property.

Gold Highlights

The Project also covers a 30-kilometre extent of the Rocky Brook-Millstream Fault system;

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; and

Recent discovery in 2023 of high-grade gold assays from grab samples* assaying up to

5.23 g/t

Au over a 350 metre

strike length at Fournier Lake.

The Rocky Brook Project

The Rocky Brook Project comprises 36,533 hectares in 83 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, 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, which is the largest undeveloped VMS project in

New Brunswick owned by Canadian Copper Inc. (

Figure 1

).

The Bathurst Camp

The BMC is one of the world's oldest base metal (lead, zinc, copper, gold, and silver) mining districts

hosting one of Canada's largest 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**).
