ROCKLAND RESOURCES PROVIDES BERYLLIUM-BEARING SAMPLES TO MIRESSO FUSION ENERGY RESEARCH COMPANY

Beryl samples from Rockland Resources Ltd.'s Meteor project in Juab county, Utah, have been provided to MiRESSO Co. Ltd., a fusion energy research company located in Misawa-shi, Japan. Meteor is one of three beryllium properties held by Rockland in the Spor Mountain region that also hosts the world's largest beryllium mine operated by Materion Corp.

Rockland president Will Rascan stated: "The minerals bertrandite and beryl are the only economic sources for beryllium, and Rockland is the only company that is actively exploring and developing these two sources. As we advance our relationship with MiRESSO, we will seize this opportunity to advance our exploration for beryl at our Meteor project and elsewhere in this uniquely beryllium-rich region of Utah."

Arrangement with MiRESSO Co. Ltd.

Through its technical adviser Chris Dorn, the company has an arrangement with MiRESSO, which is engaged in the construction of an energy-efficient, cost-effective process for the extraction of beryllium from beryl. Beryllium is integral to the operation of molten salt nuclear energy systems, and more will be needed than is currently produced. MiRESSO anticipates a future beryllium shortage and sees beryl as an essential source. While an adviser for Rockland, Mr. Dorn also serves as a special technical and business adviser to MiRESSO.

President Rascan further commented: "Beryllium is a critical element for meeting future clean nuclear energy needs. This reality was announced just last week with the agreement between Google, Kairos Power and the Tennessee Valley Authority to develop a molten salt nuclear power plant to drive their Google data centres, an announcement lauded by Materion."

Meteor project: Located 70 kilometres west of the Materion mine along a well-maintained gravel road, Meteor includes historic mines and prospects focused on tungsten with beryl reported in zoned pegmatites. Most of the world occurrences of beryl are in zoned pegmatites, with larger crystals near the centre and smaller crystals at the margins. Beryl also associates with tungsten (as scheelite) in the pegmatites.

Sample collection: Zoned pegmatite weighing roughly 50 kilograms was collected from the East Apex mine area and hand-cobbed with potential beryl crystals removed on the basis of their physical characteristics. These features included a hardness of approximately eight on the Mohs scale, a hexagonal crystal shape and striation lines parallel to the crystal length that are typical of beryl. Note that many of these features are also shared with quartz, which is also a common mineral in the pegmatites, so it was not possible to ensure a pure beryl concentrate by physical features alone. Roughly 200 grams of the beryl-quartz mixture was concentrated from this method. From this mixture, a few grams of beryl crystals were concentrated by visual means.

Laser-induced breakdown spectroscopy analysis: The beryl crystal concentrate and the beryl-quartz samples were both tested for the presence of beryllium using the Z-200 C LIBS hand-held analyzer that is marketed by SciAps (Andover, Mass., United States). Laser-induced breakdown spectroscopy uses a laser in combination with aspirated argon gas to create a plasma that liberates light elements for detection including beryllium. Currently, there are no beryllium standards to calibrate the LIBS, and so the SciAps qualitative protocol Element Pro was used to detect the presence of beryllium. Element Pro distinguishes the signal amplitude for an element of interest against a background threshold. Both samples indicated the presence of beryllium. Both samples were sent to MiRESSO. Rockland continues to work with SciAps to develop a quantitative beryllium analytical protocol that includes creating its own in-house standards for calibration of the instrument.

Note that Meteor is an early-stage exploration project that has been visited only once by the company, and insufficient data exist to assess the potential economics of beryl deposits on the property.

Additional Utah beryllium projects

Claybank: Only five kilometres east of Materion's beryllium mines at Spor Mountain and connected by a paved road leading to their processing facility, Claybank is the most strategically positioned of the Rockland properties. Mineralization at Claybank is constrained to an altered rhyolite tuff breccia erupted against a dolomite breccia and above a welded red rhyolite tuff. This geological relationship is believed to have constrained the hydrothermal fluids that generated bertrandite within the tuff unit. The property saw historical drilling in 1987 with 31 vertical drill holes distributed along strike of the altered tuff (which is similar to the altered tuff being mined at Spor Mountain). Nineteen of the drill holes were closely spaced and identified a zone of beryllium mineralization roughly 70 metres along strike of the tuff. Historical assays for the mineralization zone reported drill hole intercepts from approximately 2,500 to 6,500 parts per million Be. In 2014, 20 of 31 historic stockpiles taken from outcrop were analyzed by Materion using a lab-based berylometer, with results showing a range from 770 to 3,216 ppm Be and a weighted average of 1,741 ppm Be. Most recently, the company conducted new sampling of all 31 stockpiles and of similar outcrops on the property (see news release dated Aug. 6, 2025). These samples were submitted for analysis and details of the sampling, and results will be provided in the coming weeks.

Beryllium Butte: Beryllium Butte is in the Honeycomb Hills roughly 50 km west of the Spor Mountain mine along a well-maintained gravel road. Grab samples collected in 2022 returned highs of 4,810, 4,290 and 1,790 ppm Be from an altered rhyolite tuff breccia (see news release dated Aug. 4, 2022). Follow-up channel sampling along strike averaged 1,142 ppm Be over 25.5 m, with a higher-grade portion returning 2,423 ppm Be over 6.13 m (see news release dated Nov. 2, 2023). For contrast, Spor Mountain ore is currently mined by the world's largest producer of beryllium (Materion, New York Stock Exchange) at an average grade of 2,460 ppm Be. Beryllium Butte is permitted for drilling through the U.S. Bureau of Reclamation with the intent to drill later this year.

Arrangement with Mithril Mining Corp.

Rockland was fortunate to add Taylor Sulik as a technical adviser just after acquiring the Meteor tungsten-beryllium claims. Mr. Sulik is president of Mithril Mining, which is focused on the reshoring, extraction and processing of United States-based deposits of these critical minerals. Through a partnership between Utah-based Hinkinite Resources, Mithril Mining has acquired a tungsten processing facility in Tooele county, Utah, that processed 275 tons of tungsten concentrate as recently as 2017. The partnership intends to revamp and rehabilitate the facility, as well as expand the scope of critical minerals able to be processed and become a hub-and-spoke processing centre for the Great basin of Utah and Nevada. The Tooele facility has power, water and permitting in place, and is located only 40 kilometres north of the Meteor property. Rockland and Mithril are engaged in conversations that will provide expertise in processing techniques for beryllium and other critical mineral deposits in the Great basin.

Promotional activities

Rockland further announces it has engaged with Aktiencheck.de AG and its principal, Stefan Lindam, pursuant to which Aktien will assist with an initial European marketing awareness program. The engagement includes up to five editorial write-ups, stand-alone e-mail marketing campaign distribution of the editorial write-ups to opt-in e-mail addresses of active investors, targeted distribution of the editorial reports to active investors, distribution of the editorial write-ups through social media to active financial investors, and distribution of the editorial write-ups through the aktiencheck website and search engine marketing. The program commenced Aug. 8, 2025, and will end after the fifth write-up is completed. The cost of the engagement is 25,000 euros. Options or shares of the company were not issued.

The company further announces it contracted Hallgarten + Company Ltd. to write an editorial research report at the cost of $7,500 (U.S.) on June 27, 2025. Options or shares of the company were not issued.

About beryllium

Beryllium is a high-value and essential light metal with wide applications in the aerospace, computer, telecommunications, electronics, medical, satellite, clean energy and defence sectors. The primary ore minerals of beryllium are bertrandite and beryl. Anticipated future needs for beryllium, combined with the limitation of having only a single mine for U.S. domestic use, places beryllium as both a critical and a strategic mineral according to U.S. government sources.
