Alto Ruri Gold Project: High Sulfidation Epithermal System in Peru

The Alto Ruri Gold Project is located approximately 15 kilometres south of Barrick Gold’s Pierina Mine, which is currently in its closure and reclamation phase following more than two decades of production.

Pierina demonstrated the presence of a robust high-sulfidation epithermal gold system within Peru’s Cordillera Negra belt. Alto Ruri shares similar geological characteristics, including vuggy silica and advanced argillic alteration, supporting the potential for a preserved epithermal system within the same regional corridor.

The Alto Ruri Gold Project comprises approximately 4,700 hectares of wholly owned mineral concessions situated within Peru’s prolific Miocene Tertiary Volcanic Arc, host to multiple world-class gold and copper deposits.

Initial drilling by Compañía de Minas Buenaventura in 1997 included 12 shallow drill holes totaling 2,254.5 metres. (Refer to the Company’s news release – March 4th, 2024).

The most significant intercept from Hole 001-97 returned

• 131 metres grading 2.55 g/t gold from surface, including
• 54 metres grading 5.39 g/t gold

These results were re-assayed in 2011, confirming the presence of a well-developed high-sulfidation epithermal system associated with vuggy silica and advanced argillic alteration.

True widths remain undetermined, and modern confirmation drilling is planned as part of the Company’s systematic advancement strategy.

The Alto Ruri Gold Project represents a modern re-evaluation opportunity within a proven Andean gold district that has not undergone comprehensive exploration in nearly three decades.

GRANDE PRAIRIE, ALBERTA (February 24, 2026) TheNewswire – Angkor Resources Corp. (TSXV: ANK,OTC:ANKOF) (‘ANGKOR’ OR ‘THE COMPANY’) announces the completion of a trenching and sampling program at the CZ Gold Prospect in Ratanakiri Province, Cambodia.

As previously announced (see Angkor Resources ADVANCES EXPLORATION ON CZ GOLD AND WILD BOAR PROSPECTS, ANDONG MEAS LICENSE, CAMBODIA), the Company’s mineral exploration team initiated a large-scale trenching program at the CZ Gold Prospect, located on the west side of the Canada Wall prospect. The program is designed to determine the geology, structure and orientation of the quartz stockwork zone and its wall rocks, and to collect representative samples for analysis.

The trenching program consisted of twelve trenches excavated across the CZ Gold Prospect area. Each trench measured approximately five meters in length, two meters in width, and five meters in depth. Due to the steep slope and required depth of the trenches, the Company made the decision to utilize excavation equipment to safely and efficiently complete the program.

Figure 1: The slope and depth of the trenches contributed to the decision of using equipment for the excavation program at the CZ Gold Prospect.

The excavation process involves digging each trench to the target depth, at which point Angkor’s field team entered the trench to collect samples directly from the exposed geology, including veining and stockwork visible in the trench walls. Once sampling was complete, the team exited the trench and all samples are marked, bagged, and prepared for testing and analysis on the surface. As soon as sampling was finished at each location, the trenches were filled in and the site was restored.

Figure 2: Angkor staff sorting sample material and preparing samples for sieving, analysis, and testing,

The Company collected 298 samples of veins, side walls, and cross sections from the twelve trenches. Each sample will be split into three parts for different methods of analysis: one part for panning in the creek adjacent to the prospect, one part for portable X-ray fluorescence (XRF) analysis, and one part for fire assay. This multi-method approach is intended to provide a comprehensive geochemical characterization of the stockwork zone and to evaluate gold content across the target area.

The Company completed sampling this weekend and has started several weeks of analysis of the samples before interpretation of the data can be completed.

Gold Runner Exploration Inc. (CSE: GRUN) (FSE: CE70) (‘Gold Runner’ or the ‘Company’) is pleased to announce that the Canadian Securities Exchange has approved Gold Runner’s Option Agreement, dated January 21, 2026 as amended January 26, 2026, with the B-ALL Syndicate Ltd. (‘B-All’ or the ‘Optionor’) to acquire a 100% interest in the Golden Girl Property (‘Golden Girl Property’, ‘Golden Girl’ or ‘Property), from the B-ALL Syndicate, the same team that generated and staked Goliath Resources (TSXV: GOT) Surebet Discovery and contributed to advancing that discovery to where it is today. The B-ALL Syndicate also generated and staked the Big One discovery that was subsequently optioned to Juggernaut Exploration (TSXV: JUGR,OTC:JUGRF) and is situated adjacent to Galore Creek. Golden Girl is located approximately mid-way between Goliath’s Surebet Discovery and Juggernaut’s Big One discovery.

As described in the Company’s news release dated January 23, 2026, the Golden Girl property covers an area of 8,471 hectares (ha) in the Iskut River region of Northwestern British Columbia, just 17 kilometers from the Snip Mine and 14 kilometers from the Bronson Airstrip. Exploration conducted by B-ALL on the Golden Girl property identified a large new gold-silver system measuring 12 km by 7 km. The system features a gold-rich core surrounded by a silver-rich halo. Highlights from the 2024 exploration program include grab samples assaying up to 11.28 g/t Au, 3,262 g/t Ag, 5.37% Cu, 20% Pb, and 14.15% Zn, and channel cuts assaying up to 3.74 g/t Au, 2105.45 g/t Ag, 0.88% Cu, 5.48% Pb, and 7.42% Zn.

The nearby, past-producing Snip Gold Mine, historically produced approximately 1 million ounces of gold, 390,000 ounces of silver, and 249,276 kilograms of copper (at an average 127.5 grams per ton gold over 8 years). Eskay Creek, which lies approximately 60 km east of Golden Girl, produced approximately 3.3 million ounces of gold and 160,000 ounces of silver between 1994 and 2008 (with an estimated 3.3 million ounces of gold, 88 million ounces of silver in reserves). It should be noted that Eskay Creek Mine has recently been permitted to re-commence mining operations – see Skeena Resources Ltd. news releases dated January 28, 2026, and February 3, 2026. The reader is reminded that the information provided herein from neighbouring projects and properties is not necessarily indicative of resources and should not be relied upon for the determination of mineralization or potential results of the Company’s properties.

High-grade mineralization at Golden Girl occurs in structurally controlled shear zones within sulphide-rich veins, stockwork, and breccias, similar to the nearby Snip Gold Mine. Hydrothermal fluids took advantage of pre-existing structures to deposit gold-silver-rich mineralization as well as sulphides such as chalcopyrite, galena, and sphalerite associated with quartz-carbonate-rich veins. Pervasive alteration associated with fluid infiltration is often observed surrounding the zones of strong gold-silver mineralization assaying up to 11.28 g/t Au, 3,262 g/t Ag, 5.37% Cu, 20% Pb, and 14.15% Zn and channel cuts assaying up to 3.74 g/t Au, 2105.45 g/t Ag, 0.88% Cu, 5.48% Pb and 7.42% Zn.

More than 95% of the Golden Girl property remains unexplored. Rapid glacial retreat and snowpack abatement over the last 35 years have revealed vast areas of new outcrop that have never seen historical surface exploration. Gold Runner has begun planning and scheduling of prospecting, sampling, and mapping, as well as detailed geophysical surveys over the property during the current exploration season in preparation for the inaugural drill program.

Pursuant to the terms of the Option Agreement, the Company has paid the initial option fee of $250,000. And the Company has also issued to the members of the B-ALL Syndicate, an aggregate of 1,830,000 common shares at a price of $1.13 per common share plus 1,830,000 common share purchase warrants exercisable within 5 years from the date of issuance at an exercise price of $1.14 per common share. The securities issued hereunder are subject to the requisite four-month and one-day hold period from the date of issuance. The parties to the Option Agreement are arm’s length.

Chris Wensley, CEO of Gold Runner, states, ‘We are now fully funded to undertake and complete the 2026 exploration program on Golden Girl. Preparations are already underway to begin expanding on the excellent work done by the B-ALL Syndicate team, who generated Golden Girl. We are on schedule to commence this vital and much-anticipated field work by July 2026 and define our maiden drill program for the following season. This is a tremendously exciting time for the Company and our team. We look forward to executing and delivering on our plan and bringing notable results to our shareholders.’

Stallion Uranium Corp. (the ‘Company’ or ‘Stallion’) (TSX-V: STUD; OTCQB: STLNF; FSE: FE0) is pleased to announce the completion of an extension to its previous ground gravity survey along the Coyote Corridor, located within the Southwestern Athabasca Basin Joint Venture (‘JV’) Project in partnership with Atha Energy Corp. (TSX-V: SASK).

The recently completed program represents a direct extension of the Company’s original gravity grid and was designed to expand coverage over gravity responses observed along the margins of the initial survey area. The objective of the extension was to determine whether these edge anomalies form part of a larger, continuous gravity feature associated with the interpreted structural corridor at Coyote.

Data from the expanded survey is currently undergoing processing, quality control, and preliminary modelling. The Company will provide results once interpretation has been completed.

Highlights:

• Significant gravity low anomaly identified, closely resembling the geophysical signatures of NexGen Energy’s Arrow Deposit and other significant discoveries in the Athabasca Basin
• Structural and geophysical features align with those of the Arrow Deposit and PCE discovery, reinforcing the potential for Tier-1 uranium mineralization
• Gravity anomaly located in a structurally complex corridor, characterized by intersecting conductors and breaks, which are prime settings for uranium deposition
• Ongoing 3D Inversion of Ground Gravity to identify depth and shape of the gravity anomaly

‘The completion of this gravity extension is an important step in systematically advancing the Coyote Target,’ said Matthew Schwab, CEO of Stallion Uranium. ‘Expanding the grid ensures we fully evaluate gravity responses identified at the edges of the initial survey and maintain a disciplined, data-driven approach to exploration.’

Darren Slugoski, Vice President Exploration, added,

‘This extension allows us to properly assess the continuity of gravity features along the structural corridor before finalizing drill targeting. With data processing underway and a potential eastern grid about to commence, we continue to build a comprehensive geophysical dataset across the broader Coyote trend.’

Figure 1: Ground Gravity Survey Location showing Extension of Corridor to the SW

Survey Extension Overview:

The gravity survey extension increases overall coverage across the Coyote structural corridor and enhances density control along strike and across interpreted conductive breaks. The combined original and extended grid now provides improved resolution of subsurface density variations that may be associated with alteration and basement structural complexity.

Gravity surveys are a key component of Stallion’s integrated exploration approach, as gravity lows within the Athabasca Basin are commonly associated with hydrothermal alteration systems developed along graphitic basement structures.

The survey encompassed a total area of 2,097 hectares, with 2,226 gravity stations strategically placed to detect subsurface variations in density that may indicate uranium alteration. The results revealed a substantial gravity low anomaly, a hallmark feature associated with large-scale uranium deposits, such as NexGen Energy’s Arrow Deposit. The Arrow Deposit, one of the most significant uranium discoveries in the Athabasca Basin, shares multiple geological and geophysical similarities with the Coyote Target, strengthening confidence in the potential for a high-grade uranium discovery.

About the Ground Gravity Survey:

Concluding February 10, 2026, MWH Geo-Surveys (Canada) Ltd. carried out a gravity survey at the Coyote Target in Saskatchewan. The survey utilized a customized L&R digital, electronic feedback gravity meter, operated via proprietary controller software. These advanced gravity meters, incorporating electronic levels and electronic nulling, ensure fast, accurate, and reliable readings, particularly in cold-weather conditions.

At each gravity station, GControl software, developed by MWH Geo-Surveys, recorded gravity samples at 1-second intervals. The resultant average of these readings was used as the final gravity measurement, significantly reducing high-frequency noise caused by wind and ground motion. Additionally, GControl calculated real-time, location-specific tidal corrections during data collection, enhancing the accuracy and reliability of the survey results.

With a typical mean data accuracy of 0.02 mgals, MWH Geo-Surveys continues to set the standard for high-resolution gravity surveys, delivering reliable results for resource exploration and geophysical studies.
