Magna Terra Outlines Stream Sediment Anomalies on the Humber Copper-Cobalt Project, Newfoundland
Magna Terra Outlines Stream Sediment
Anomalies on the Humber Copper-Cobalt
Project, Newfoundland
Toronto, Ontario--(Newsfile Corp. - February 19, 2026) -
Magna Terra Minerals Inc.
(TSXV: MTT)
("
Magna Terra
" or the "
Company
") is pleased to announce that it has received analytical results from a
regional stream sediment geochemical survey over the 100% owned Humber Copper-Cobalt Project
(the "Humber Project" or the "Project") located in western Newfoundland. The stream sediment samples
were collected to further assess regional prospectivity for Sediment-hosted Stratiform Copper ("SSC")
mineralization and complement the recently completed airborne geophysical survey covering the
property (see news release dated September 18, 2025) (
Figures 1, 2, 3, and 4
).
A total of 189 stream sediment samples were collected systematically across Blocks 1 and 2,
representing 68% of the 49,925-hectare Project area, from streams that were accessible by roads or
short (< 1 km) traverse. The stream sediment samples were analysed at Eastern Analytical Ltd. in
Springdale, NL for gold and multi-element ICP analysis. The results highlight key areas with multi-
element anomalies (Cu, Co, Zn, and Pb) that are spatially coincident with electro-magnetic conductors
from the recently completed airborne VTEM survey.
Of the 189 samples collected over the property, cobalt values range between 4 and 409 ppm Co with 10
of 189 (5.3%) assaying over 94.6 ppm; copper values range between 5 and 70 ppm Cu with 9 of 189
(4.8%) assaying over 30 ppm; lead values range between 9 and 81 ppm Pb with 9 of 189 (4.8%)
assaying over 39 ppm; zinc values range between 33 and 617 ppm Zn with 9 of 189 (4.8%) assaying
over 220 ppm, and gold values range between <5 and 17 ppb Au with 15 of 189 (7.9%) over the 5 ppb
detection limit
(Figures 2, 3, and 4)
.
Elevated values for Cu, Co, Pb, and Zn occur in clusters, particularly in the northwestern quadrant of
Block 1 where, anomalous stream sediment samples are spatially coincident with conductive shale/slate
sequences and also with the anomalous Co lake sediment sample sites, which were the initial basis for
acquiring the Humber Project. These shale/slate units are ideal hosts to SSC mineralization. An analysis
of the stream sediment data and related drainage catchments generated targets with a cumulative area
of 5,588-hectares. The Company plans to complete the survey over the remaining project area as part of
its comprehensive exploration plans commencing in the spring.
Humber Project Highlights
Discovery of
2.2 km
of surface copper mineralization at Hughes Lake, with potential for further
minimum
1.7 km
of strike extent;
Host to regionally anomalous Cu, Co, Ag, Pb +/- Au, Mo, As, and Sb lake sediments;
Airborne conductors coincident with lake sediment anomalies;
8+ km
Hughes Lake Copper-Cobalt Trend;
Analogous to the Kalahari Copper Belt, Namibia and Botswana; Central African Copper Belt,
Zambia and the Democratic Republic of Congo (DRC); and the Kupferschiefer Belt, Poland;
Globally, these Sediment-hosted Stratiform Copper ("SSC") deposit types represent 20% of Cu
production** and 60% of Co production^^;
District-scale land package now comprising
49,925 hectares
;
Located within the premier mining jurisdiction of Newfoundland and Labrador;
Year-round accessibility with road access to the majority of the Project;
First mover advantage in a previously unrecognized area of exploration potential; and
Acquired through staking - cost effective acquisition and with no underlying royalties or option
payments.
"We are very pleased with the stream sediment sampling results, completed during our initial
exploration program on the Project in the summer of 2025. These results continue to generate
multiple coincident geochemical and geophysical targets and zones of copper-cobalt mineralization
on the broader property package outside of our initial Hughes Lake discovery area. The strong tenor
of cobalt, copper, lead, and zinc in stream sediments, outlines targets with a cumulative area of 5,588-
hectares, that are coincident with airborne conductivity. This continues to support our view that the
Humber Project has the potential to host Sediment-hosted Stratiform Copper deposits.
In addition to the stream sediment samples, we are awaiting the results of an additional 821 soil
samples that were collected along strike of the 2.2 kilometre long zone of copper mineralization
discovered at the Hughes Lake Trend with the goal of expanding the potential footprint of the
mineralized zone. These results will be released in an upcoming press release when available."

Lake Sediment Geochemistry and Global Analogues
The Project is underlain by sedimentary rocks of the Humber Arm Allochthon and adjacent plutonic and
volcanic Hughes Lake Complex, which is centred on a series of anomalous lake sediment samples
(Davenport et al., 1996) that show regionally elevated levels of Co (up to 160 ppm), Ag (up to 0.6 ppm),
Pb (up to 84 ppm), Cu (up to 185 ppm), As (up to 142 ppm), Mo (up to 15 ppm), and Au (up to 10 ppb).
An analysis of the lake sediment geochemical data via Principal Component Analysis has indicated that
the metal suite present within the Project area is likely related to a black shale source, as many of the
anomalous lake sediments have low-Ni values which precludes association with the nearby ophiolite
complexes to the immediate west.
This metal signature (Cu, Co, Ag, Pb +/- Au, Mo, As, Sb) and geological environment is supportive of the
area being host to SSC deposits. SSC deposits host 60% of global Cobalt production^^ and 20% of
global Copper production** in deposits such as the Central African Copper Belt, which is thought to be
analogous to the geological setting of the Humber Copper-Cobalt Project. SSC deposits are often
laterally continuous along bedding and contain consistent grades (1.2 to 5% Cu)** and large resources
of by-product Au, U, platinum-group, and rare-earth elements. The exploration potential is also
underscored by the presence of base metal deposits nearby including the York Harbour and Daniels
Harbour Deposits located at lower stratigraphic levels of the region.

This news release has been reviewed and approved by David A. Copeland, P.Geo., a non-independent
consultant to the Company and a "Qualified Person" as defined under National Instrument 43-101 -
Standard for Disclosure for Mineral Projects
.
All stream sediment samples were collected systematically along streams that transect the property by
contractor GeoXplore Suveys. Stream gravel and sand was sieved to 2 mm size with the resultant 2 kg
sample submitted to Eastern Analytical Ltd. in Springdale, NL and were analysed for gold (30 g fire
assay) and multi-element geochemistry, including elements Cu, Pb, Zn, Co, and Ag (method ICP-34).
All quoted historic soil and lake sediment samples results were compiled from assessment and
government reports obtained from the government of Newfoundland and Labrador. The Qualified Person
has not completed sufficient work to validate these historic results.
