Gold Terra Confirms Campbell Shear Gold Potential to a Vertical Depth of 2580 Metres, Con
Mine Option Property, NWT
Vancouver, BC – May 26, 2025 – Gold Terra Resource Corp. (TSX-V: YGT; Frankfurt: TX0; OTCQX: YGTFF)
(“Gold Terra ” or the “ Company”) is pleased to report that wedge hole GTCM25 -056A intersected
anomalous gold in the Campbell Shear (CS) from 2680.5 to 2 703.5 metres downhole depth on the Con
Mine Option (CMO) Property. The results are very encouraging, confirming the existence of the CS more
than 600 metres below the mine. The CS intersection is gold and silver anomalous (up to 0.5 g/t Au and
12.6 g/t Ag), which the Company views as comparable to historical low -grade intersections in the mine
that were outside the previous mined high-grade shoots.
In addition, higher-grade gold values (7.81 g/t Au over 0.5 metres) were intersected in the footwall of the
CS within brecciated pyrite-pyrrhotite quartz veins, identical to the lowest levels of the mine. The CS was
initially intersected at depth in hole GTCM23-055, with 12.63 g/t Au over 1.7 metres (refer to November
15, 2023 news release), 200 metres below the existing historic underground workings
Chairman and CEO, Gerald Panneton, commented, "Hole GTCM25-056A confirms the gold potential of the
CS at more than 600 metres below the current depth of the historic Robertson Shaft (-1900 metres). The
gold and silver anomalous CS intersection of 23 metres is typical of a pinch section of the usual wider or
swelling altered CS. With this technical success and confirmation of the CS potential at depth, we can pause
the deep drilling and focus on our targets near surface. As such, there is no need to spend more money
from surface, as the CS potential is confirmed.”
The objective of the 2025 wedge hole drilling program is to continue testing for high-grade gold in the CS
(past production of 5.1 Moz @ 16 g/t ), refer to Gold Terra’s Oct. 21, 2022 Technical Report) on the Con
Mine below the historic Con Mine underground workings. Under the CMO agreement, the Company has
the right to acquire 100% of the CMO property from a subsidiary of Newmont Corporation, subject to the
fulfillment of certain conditions set out in the agreement, as reported in the Company's news release
dated November 22, 2021.
Wedge Hole GTCM24-056A Highlights
The drilling initially intersected a gold anomalous zone between 2680.5 to 2703.5 metres downhole depth
in the CS with chlorite dominant alteration with assay results between 0.1 g/t and 0.54 g/t . This
intersection is comparable to historical low -grade intersections in the mine that were outside the high -
grade shoots but were in general proximity to higher grade zones.
Further down the hole , gold was intersected in the brecciated style veins . F rom 2,773.38 to 2824.74
metres downhole depth brecciated veins with pyrrhotite (po)-pyrite (py) were intersected, including 7.81
g/t Au over 0.5 metres, and 3.36 g/t over 0.5 metres, as well as multiple narrow veinlets with assays
between 0.28 and 0.92 g/t Au over 0.5 to 1.0 metre sample lengths.
Historical drilling in the deepest parts of the Con Mine targeting the CS reported significant changes to
the shear character. In shallower levels the shear was dominantly sericite altered with abundant
arsenopyrite (aspy) in laminated quartz veined gold shoots. Deeper in the mine the gold shoots were
dominantly chlorite altered shears (Figure 2), and the highest-grade quartz veins were brecciated with
2 / 6
dominant py-po mineralization and minimal aspy. Hole GTCM -25-056A encountered examples of both
these styles.
The narrower 23 metres CS intersection is typical of a pinch/squeeze in the CS that is commonly observed
in upper areas of the Con Mine, but which can be proximal within a few tens of meters of the CS carrying
high grade gold (see Figure 2 level plan schematic). As such the limited drilling to date is considered highly
encouraging within the CS intersection . The footwall brecciated veins, typical of deep high -grade
mineralization styles at the Con Mine, again display characteristics indicative of potential proximity to a
high-grade shoot. Both these zones are confirmation of the Con Mine structures and the continuation of
gold mineralization 600 metres below current mine working.
Figure 1 below is a cross-section showing the master hole GTCM24 -056 and wedge hole GTCM25-056A
intersecting the CS at 2,686 metres downhole.

and the gold potential window of the CS intersected by wedge hole GTCM25-056A (see also November
15, 2023 news release).
Figure 2 below is a schematic section illustrating the exploration model for locating the discrete high
grade gold mineralization within the Campbell Shear. A level plan based on underground development
on the Campbell Shear shows the targeted alteration types (chlorite dominant). High-grade lodes have
historically been located successfully in the Campbell Shear Structure by drilling proximal to low grade
Au drill holes.

The 2023 to 2025 deep drilling programs have successfully confirmed that the CS continues to a depth of
at least 2580 metres vertical below surface and has the potential to be a large gold contributor at depth,
and below the Robertson shaft. However, the cost of the deep drilling and directional drilling over the last
2 (two) years does not make economic sense to carry on. A better approach is to do it from underground
access in the future. The deep drilling demonstrates that the CS is present at depth and has opened up a
much larger area for drilling of approximately one kilometre strike length by 600 metres vertical.
This news release reports the assay results from wedge hole GTCM25-056A from which 82 NQ sized core
samples were assayed. Assays results range from non -detectable gold to a highest assay of 7.81 g/t Au.
The Company inserts certified standards and blanks into the sample stream as a check on laboratory
Quality Control (QC). Drill core samples are cut by diamond saw at Gold Terra’s core facilities in
Yellowknife. A halved core sample is left in the core box. The other half core is sampled and transpo rted
by Gold Terra personnel in securely sealed bags to ALS preparation laboratory (“ALS”) in Yellowknife. After
sample preparation, samples are shipped to ALS’s Vancouver facility for gold analysis. Gold assays of >3
g/t are re -assayed on a 30 g split by fire assay with gravimetric finish. Samples with visible gold are
additionally assayed using a screen met allic method. ALS is a n independent certified and accredited
laboratory service. ALS routinely inserts certified gold standards, blanks and pulp duplicates, and results
of all QC samples are reported.
Drill holes were drilled at right angles to the structure hosting the mineralization and dip angles of holes
were designed to intersect the zones as close to normal as possible. Zones reported here are interpreted
to be approximately 90 percent true thickness.

Osisko Gold Royalties Ltd Exercise
Osisko Gold Royalties Ltd has completed the exercise of the first tranche of their agreement with Gold
Terra, and Gold Terra has received payment of C$2.0 million accordingly.
About Gold Terra
The Yellowknife Project (YP) encompasses 918 sq. km of contiguous land immediately north, south and
east of the City of Yellowknife in the Northwest Territories. Through a series of acquisitions, Gold Terra
controls one of the six major high -grade gold camps in Canada. Being within 10 kilometres of the City of
Yellowknife, the YP is close to vital infrastructure, including all -season roads, air transportation, service
providers, hydro-electric power, and skilled tradespeople. Gold Terra is currently focusin g its drilling on
the prolific Campbell Shear, where approximately 14 Moz of gold has been produced, (refer to Gold Terra
Oct 21, 2022, Technical Report) and most recently on the CMO property claims immediately south of the
past producing Con Mine which produced 6.1 Moz between the Con, Rycon, and Campbell shear
structures (1938-2003).
The YP and CMO properties lie on the prolific Yellowknife greenstone belt, covering nearly 70 kilometres
of strike length along the main mineralized shear system that hosts the former-producing high-grade Con
and Giant gold mines. The Company's exploration programs have successfully identified significant zones
of gold mineralization and multiple targets that remain to be tested which reinforces the Company's
objective of re-establishing Yellowknife as one of the premier gold mining districts in Canada.

Cautionary Note to United States Investors
The Company prepares its disclosure in accordance with the requirements of securities laws in effect in
Canada, which differ from the requirements of U.S. securities laws. Terms relating to Mineral Resources
in this news release are defined in accordance w ith NI 43 -101 under the guidelines set out in CIM
Definition Standards on Mineral Resources and Mineral Reserves, adopted by the Canadian Institute of
Mining, Metallurgy and Petroleum Council on May 19, 2014, as amended ("CIM Standards"). The U.S.
Securities and Exchange Commission (the "SEC") has adopted amendments effective February 25, 2019
(the "SEC Modernization Rules") to its disclosure rules to modernize the mineral property disclosure
requirements for issuers whose securities are registered with the SEC under the U.S. Securities Exchange
Act of 1934. As a result of the adoption of the SEC Modernization Rules, the SEC will now recognize
estimates of "Measured Mineral Resources", "Indicated Mineral Resources" and "Inferred Mineral
Resources", which are defined in substantially similar terms to the corresponding CIM Standards. In
addition, the SEC has amended its definitions of "Proven Mineral Reserves" and "Probable Mineral
Reserves" to be substantially similar to the corresponding CIM Standards.
U.S. investors are cautioned that while the foregoing terms are "substantially similar" to corresponding
definitions under the CIM Standards, there are differences in the definitions under the SEC Modernization
Rules and the CIM Standards. Accordingly, there is no assurance any Mineral Resources that the Company
may report as "Measured Mineral Resources", "Indicated Mineral Resources" and "Inferred Mineral
Resources" under NI 43 -101 would be the same had the Company prepared the Mineral Resource
estimates under the standards adopted under the SEC Modernization Rules. In accordance with Canadian
securities laws, estimates of "Inferred Mineral Resources" cannot form the basis of feasibility or other
economic studies, except in limited circumstances where permitted under NI 43-101.
