Gold Terra Resource Corp: Gold Terra Announces 5.88 g/t Gold over 19.00 Metres Including 18.50 g/t Gold over 4.0 Metres in the Yellorex Area, Con Mine Option Property, Yellowknife, NWT

VANCOUVER, BC / ACCESS Newswire / June 23, 2026 / Gold Terra Resource Corp. (TSXV:YGT)(Frankfurt:TX0)(OTCQB:YGTFF) ("Gold Terra" or the "Company") is pleased to announce assay results from an additional eleven (11) holes of the 2026 Winter Drill Program targeting the Yellorex zone immediately south of the past producing Campbell Shear (CS), historic Con Mine (1938-2003). The current drilling program aims at confirming some historical holes and to potentially expand Company's near surface Mineral Resource Estimate (MRE) on the Con Mine Option property.

Assay results are shown in Table 1 and include:

• Hole GTY26-22 which intersected 5.88 g/t Au over 19.00 metres from 268 metres to 287 metres downhole, including 18.50 g/t over 4 metres starting at 268 metres, including 27.50 g/t over 2 metres starting at 269 metres, and including 6.72 g/t over 5.5 metres starting at 281.5 metres which includes 9.18 g/t over 3.53 metres starting at 282.47 metres.

• Hole GTY26-011 intersected 2.18 g/t Au over 26.1 metres from 195.7 metres to 221.8 metres, including 10.27 g/t over 3.2 metres starting at 207.9 metres, and including 3.71 g/t over 3.1 metres starting at 218.7 metres.

• Hole GTY26-018 intersected 19.39 g/t Au over 3.5 metres from 67 metres to 70.5 metres.

Under the Con Mine Option (CMO) purchase agreement, the Company has the right to acquire 100% of the CMO property from a subsidiary of Newmont Corporation ("Newmont"), subject to the fulfillment of certain conditions set out in the agreement, as reported in the Company's news release dated November 22, 2021. Gold Terra's option on the CMO with Newmont is until November 21, 2027.

Chairman and CEO, Gerald Panneton, commented, "The Campbell shear target in the Yellorex area continues to deliver high-grade assay results. It further demonstrates the potential and continuity of the Yellorex Zone, reinforcing the Company's confidence in its drilling strategy to seek to expand Gold Terra's near-surface resource estimate on the CMO Property. The Campbell Shear structure is our highest priority target as the Con Mine produced historically more than 5 million ounces of high-grade gold (16 g/t Au) (see Oct. 21, 2022 Technical Report)."

Assay Highlights

Assay intersections from holes GTY26-011, 014, 015, 016, 017. 018, 019, 020, 022, 023A and 024 are shown in Table 1 below. All Yellorex drill holes intersected the Campbell Shear, characterized by quartz-ankerite and smoky quartz veining with strong sericite-dominated alteration, a key association with gold mineralization in the CS. The main geological host is mafic volcanic. The deposit remains open at depth, illustrating the potential to add resource ounces.

• Drill program targeting the 103N Zone north extension of the Campbell Shear

• Drilling the Historical tailings for potential unrecovered gold to start in August 2026

• Q3 2026 MRE, adding 20,000 metres of past drilling including 50% alone for the Walsh Lake gold corridor

• Year End 2026 Preliminary Economic Assessment (PEA)

• Gap analysis and baseline studies for the Initial Permitting process

Technical Appendix

This news release reports the assay results from eleven (11) drill holes from which 509 core samples were assayed. Assays results range from non-detectable gold to a highest assay of 36.6 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 NQ size core, 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 transported 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 50 g split by fire assay with gravimetric finish. Samples with visible gold are additionally assayed using a screen metallic method. ALS is a 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.

The technical information contained in this news release has been reviewed and approved by Joseph Campbell, a Qualified Person as defined in National Instrument 43-101 - Standards of Disclosure for Mineral Projects and Senior Technical Advisor for the Company.

About Gold Terra

The Yellowknife Project (YP) encompasses 836 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 historical 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 focusing its drilling on the Campbell Shear, where approximately 14 Moz of gold has been produced in the past, (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 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 seeking to re-establish Yellowknife as one of the premier gold mining districts in Canada.

Information Concerning Estimates of Mineral Resources
Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. Therefore, investors are cautioned not to assume that all or any part of an Inferred Mineral Resource could ever be mined economically. It cannot be assumed that all or any part of "Measured Mineral Resources," "Indicated Mineral Resources," or "Inferred Mineral Resources" will ever be upgraded to a higher category. The Mineral Resource estimates contained herein may be subject to legal, political, environmental or other risks that could materially affect the potential development of such mineral resources. Refer to the Technical Report, once filed, for more information with respect to the key assumptions, parameters, methods and risks of determination associated with the foregoing.

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 with 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 were permitted under NI 43-101.
