Highlights

• Thanksgiving, historical drill core to 10.46% WO₃: Northair Mines hole T-81-1 returned 3.01% WO₃ over 3.54 metres, including 4.74% WO₃ over 2.03 metres and 10.46% WO₃ over 0.51 metres, and hole T-81-2 returned 4.27% WO₃ over 1.52 metres, including 9.08% WO₃ over 0.51 metres (1981, core lengths).²
• Thanksgiving, surface samples to 16.2% WO₃: Kerr Addison Mines sampled the showings in 1981 and returned up to 16.2% WO₃ in selected samples, and a separate character sample returned 14.9% WO₃.³ Hand trenching exposed about 25 metres of scheelite bearing skarn.⁴
• Thanksgiving, on a paved highway and last drilled in 1981: Highway 23 runs beside the property, 20 to 25 kilometres north of Revelstoke.⁵ No diamond or percussion drilling has been recorded since Northair's 1981 program⁶, and the Company is not aware of any LiDAR or drone magnetic survey over the property.
• Five T's, five tungsten occurrences along about 10 kilometres: The claims cover all five tungsten occurrences recorded in BC MINFILE at the head of Albert Creek, including the Ice zone, mapped at surface as about 420 metres long and 3 to 20 metres wide, and a skarn band at EX 11 traced for 762 metres.⁷ All 18 soil and stream sediment samples from the 1985 program were anomalous in tungsten, at 95 to 1,600 ppm W. The geologist who completed that work compared the setting to the Sangdong tungsten deposit in South Korea and the Mittersill tungsten deposit in Austria⁸; those deposits are not necessarily indicative of mineralization at the Five T's.
• Rio Grande, scheelite float to 9.14% WO₃: Four float samples collected by Denison Mines in 1980 returned 0.43% to 7.25% W (0.54% to 9.14% WO₃), and Denison concluded that the frequency and grade of the float were "sufficient to suggest a significant source."⁹ The interpreted source has never been sampled.¹⁰
• A North American tungsten portfolio: On closing, Allegiance will hold four tungsten projects in Canada and the United States, including Golden Scheelite in Nevada, a past producer that shipped tungsten ore in 1953 and 1954 under the U.S. government's Defense Production Act tungsten purchase program.¹¹

Vancouver, British Columbia--(Newsfile Corp. - October 13, 2026) - Allegiance Resources Corp. (CSE: ALLG) (FSE: BG5) ("Allegiance" or the "Company") is pleased to announce that it has entered into a definitive asset purchase agreement (the "Agreement") to acquire a 100% interest in the Thanksgiving, Five T's and Rio Grande tungsten projects (the "Transaction") in British Columbia (collectively, the "Properties").

The Properties comprise 14 mineral claims covering approximately 1,905 hectares near Revelstoke and Shuswap Lake, British Columbia.¹² On closing of the Transaction (the "Closing"), Allegiance will hold four tungsten projects covering approximately 2,046 hectares in British Columbia and Nevada.¹³

Union Carbide Canada Mining, Canada Tungsten Mining, Amax, Denison Mines, Kerr Addison Mines, Northair Mines, Noranda Exploration and Active Minerals explored the Properties and surrounding ground between 1971 and 1985. They drilled, trenched, mapped and sampled tungsten across the three Properties.¹⁴ At the Thanksgiving property, Northair Mines drilled 85 holes in 1981¹⁵, and no diamond or percussion drilling has been recorded on the property since.¹⁶

"Serious mining companies found tungsten at surface and in drill core on these properties, and then the work stopped," said Kelly Abbott, President and Chief Executive Officer of Allegiance.¹⁷ "Thanksgiving has drill core grading 4.74% WO₃ over 2.03 metres beside a paved highway north of Revelstoke, and no one has drilled it in 45 years.¹⁸ The Five T's has five tungsten occurrences along a 10 kilometre trend, and Rio Grande has scheelite float grading up to 9.14% WO₃ from a source that has not been located.¹⁹ Together with Golden Scheelite in Nevada, Allegiance will hold four tungsten projects in Canada and the United States as U.S. defence procurement rules on tungsten tighten in January 2027.²⁰ Our first step is to rebuild the 1981 Thanksgiving data in three dimensions with modern surveys and use it to plan the next round of drilling."

Thanksgiving Tungsten Project

Thanksgiving lies on Highway 23 on the east bank of the Columbia River, about 20 to 25 kilometres north of Revelstoke, with paved road access (BC MINFILE 082M 187).²¹

Prospectors discovered scheelite in a fresh Highway 23 road cut in October 1980.²² Scheelite occurs in a skarn horizon within folded and structurally repeated calcareous metasediments.²³ Historical mapping identified a zoned diorite to quartz monzonite stock in the southern part of the property, and later petrological work attributed the skarn to an as yet undetected intrusion.²⁴

Historical work places the mineralized sequence within a fault block of approximately 400 by 60 metres, with the skarn unit 3 to 10 metres thick.²⁵ Kerr Addison reported in 1981 that hand trenching had exposed about 25 metres of scheelite bearing skarn on the north bank of the creek.²⁶

Kerr Addison Mines sampled the showings in April 1981 and returned 16.2% WO₃ and 1.99% WO₃ in selected samples (General Testing Laboratories, certificate 8104-2858).²⁷ A character sample submitted in December 1980 returned 14.9% WO₃ (X-Ray Assay Laboratories, report 10235).²⁸

Selected Historical Drilling²⁹

Northair Mines, 1981, Creek Zone (BC Assessment Report 10041). T-81-1 is reported from 14.03 to 17.57 metres, T-81-2 from 14.63 to 16.15 metres and T-81-3 from 12.19 to 14.78 metres. The 10.46% WO₃ result is a single 0.51 metre sample within the 4.74% WO₃ interval, and T-81-2 includes 9.08% WO₃ over 0.51 metres from 15.14 to 15.65 metres.³⁰ Intervals are core lengths; true widths are not known.

Northair recommended further evaluation of the existing data before additional drilling and withdrew in early 1982.³¹ Andaurex Resources, then the property owner, attributed the withdrawal to "current conditions and commitments in the gold mining industry."³² No diamond or percussion drilling has been recorded at Thanksgiving since 1981.³³

Planned Work at Thanksgiving

The 1981 drill, trench and sample records predate GPS and have never been compiled into a georeferenced three dimensional geological model.³⁴ Glacial and fluvioglacial deposits cover bedrock across parts of the property, which limits what surface mapping alone can see.³⁵

Allegiance intends to combine the historical drilling and geological record with high resolution LiDAR, drone magnetics and structural modelling to map intrusive contacts, repeated favourable stratigraphy and prospective skarn targets where bedrock exposure is limited.

Subject to closing and financing, the Company intends to compile and georeference the 1981 drill, trench and sample records and to fly LiDAR and drone magnetic surveys over the Thanksgiving claims to define a new generation of drill targets. The scope, budget and timing of this work will be set with the Company's qualified person.

Five T's Tungsten Project

Five T's covers 711.10 hectares at the head of Albert Creek, about 36 kilometres east of Revelstoke, and all five tungsten occurrences recorded in BC MINFILE 082N 036 to 040, distributed along a trend of about 10 kilometres.³⁶

In 1985, Active Minerals mapped the Ice zone at surface as approximately 420 metres long and 3 to 20 metres wide.³⁷ At EX 11, BC MINFILE records a continuous skarn band averaging 0.9 metres wide over approximately 762 metres.³⁸

All 18 soil and stream sediment samples from the 1985 program were anomalous in tungsten, ranging from 95 to 1,600 ppm W, and outlined a tungsten in soil anomaly of approximately 300 by 500 metres that the author described as open in all directions.³⁹

The geologist who completed the 1985 work, Chris Graf, P.Eng., of Active Minerals, described the mineralization as "strataform and widespread." ⁴⁰

Graf compared the Five T's to stratiform scheelite deposits hosted in Lower Paleozoic quartzites, including the Sangdong tungsten deposit in South Korea and the Mittersill tungsten deposit in Austria, which he described as large deposits belonging to extensive scheelite bearing tungsten provinces, and suggested that a similar large scale tungsten district may occur within the Lower Paleozoic Hamill and Lardeau Group rocks of the Kootenay Arc.⁴¹ Mineralization at Sangdong and Mittersill is not necessarily indicative of mineralization at the Five T's.

No drilling has been recorded on the Five T's.⁴²

Rio Grande Tungsten Project

Rio Grande presents a simple exploration question: where did float grading up to 9.14% WO₃ come from?⁴³

In 1980, Denison Mines followed scheelite bearing skarn float up Canyon Creek. Four float samples returned 0.43% to 7.25% W (0.54% to 9.14% WO₃), and Denison concluded that the frequency and grade of the float were "sufficient to suggest a significant source." ⁴⁴

In 1971, Amax recorded scheelite and chalcopyrite in a skarn zone along the contact of quartz monzonite with metasedimentary rocks on the RIO claims, and completed 180 feet of trenching (BC Geology, Exploration and Mining 1971).⁴⁵

Denison interpreted the source of the float as a rusty granitic dyke at about 1,040 metres elevation, which has never been sampled.⁴⁶ Allegiance intends to return to the interpreted source area using modern positioning, mapping and sampling methods.

Tungsten Supply

The U.S. Geological Survey estimates that China accounted for approximately 79% of global tungsten mine production in 2025.⁴⁷ The United States has had no tungsten mine production since 2015, and China placed selected tungsten items under export licensing in February 2025.⁴⁸ From January 1, 2027, 48 CFR 252.225-7052 extends the U.S. Department of Defense restriction on tungsten metal powder and tungsten heavy alloy to material mined, refined, separated, melted or produced in China, Russia, Iran or North Korea. Canada and the United States are not among the named countries,⁴⁹ and all four Allegiance projects are in Canada and the United States.

Transaction Terms

The Company has entered into the Agreement with the holders of the mineral claims (the "Claim Holders") and certain other vendors (collectively with the Claim Holders, the "Vendors"). As consideration for the Properties, the Company will issue an aggregate of 1,200,000 common shares (the "Payment Shares") to the Vendors on Closing and pay the Claim Holders $30,000 in cash on execution of the Agreement, which is nonrefundable, and $30,000 six months after execution of the Agreement.

The Payment Shares will be issued at a deemed price of $0.175 per share, being the closing price of the Company's common shares on the Canadian Securities Exchange on October 9, 2026, representing aggregate deemed share consideration of $210,000.

The Payment Shares are subject to a statutory hold period of four months and one day from issuance. Under the Agreement, 50% will be released four months and one day after closing, subject to registration of the claim transfer on Mineral Titles Online, and 50% ten months and one day after closing.

On closing, the Company will grant the Vendors an aggregate 2% net smelter returns royalty in respect of the Properties, shared in proportion to their interests. Allegiance will have the right to purchase 1% of the royalty for $450,000 prior to commercial production.

Closing remains subject to completion and the delivery of a National Instrument 43-101 technical report, acceptance by the Canadian Securities Exchange (if required) and other customary closing conditions. The Agreement provides for Closing before December 31, 2026.

Property Summary⁵⁰

Qualified Person

The scientific and technical information in this news release has been reviewed and approved by Ryan Versloot, P.Geo., a qualified person as defined by National Instrument 43-101, who is independent of the Company and of the Vendors.

Ryan Versloot has reviewed the historical sources cited in this news release, including BC Assessment Reports 10041, 9169 and 14749 and the BC MINFILE records, but has not verified the historical data. Verification requires field examination, resampling and access to original core, samples and laboratory records, none of which has been possible before the Company acquires the Properties.

Historical Sampling and Analytical Information

Thanksgiving surface samples were collected by Kerr Addison Mines Ltd. in April 1981 and assayed for WO₃ by General Testing Laboratories, Vancouver (certificate 8104-2858).⁵¹ The 14.9% WO₃ character sample was analyzed by X-Ray Assay Laboratories by XRF (report 10235).⁵² Thanksgiving diamond drilling by Northair Mines Ltd. in 1981 was HQ core, reduced to NQ where ground conditions required. Core was assayed by Chemex Labs Ltd. using acid decomposition followed by colorimetric determination of tungsten as the thiocyanate complex. Collar coordinates and hole orientations are recorded in Assessment Report 10041⁵³ and have not yet been compiled by the Company.

Five T's samples were collected by Active Minerals Ltd. in 1985 and analyzed by Min-En Laboratories Ltd., North Vancouver.⁵⁴ Rio Grande float samples were collected for Denison Mines Limited in 1980 and analyzed by Rossbacher Laboratories, with results reported as percent tungsten.⁵⁵ Where WO₃ equivalents are shown, W has been converted to WO₃ using a factor of 1.2611.⁵⁶

Grab, character and float samples are selective by nature and are not necessarily representative of mineralization across the Properties. Float samples are not in place and their bedrock sources are unknown. Historical drill intervals are core lengths and true widths are not known. Dimensions of geological units and mapped zones do not represent continuous tungsten mineralization, and the approximately 10 kilometre Five T's trend does not represent continuous mineralization.

Northair reported tungsten intervals in seven of its 26 diamond holes at Thanksgiving; most other holes returned low or trace values, and holes on the South and East Limbs returned 0.16% to 0.21% WO₃ over 0.50 to 1.52 metres.⁵⁷

A BC Geological Survey reconnaissance in 2000 collected 14 samples in the Ice and EX 90 area, with a maximum of 410 ppm W.⁵⁸ A 1972 government summary refers to surface diamond drilling on part of the Ice claims, but no assessment report, logs or results have been found, and a 1979 property review states that no drilling was done.⁵⁹

The Company has not verified any of the historical information, including sampling procedures, sample type and width, analytical methods, quality assurance and quality control procedures, drill hole locations or drill totals.
