Rockland Resources Receives Tentative Approval To Drill At The Claybank Beryllium Critical Mineral Project, Utah

Will Rascan, President of Rockland states "We are very pleased with the State of Utah and its proactive approach in working with us to streamline the permitting process for Claybank. Utah was recently ranked the number one jurisdiction in the world for mineral exploration and development by the Fraser Institute¹, and we look forward to a long and productive relationship with the state."

Claybank - Only five kilometers 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 position 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 meters along strike of the tuff. Historical assays for the mineralization zone reported drillhole intercepts from ~2,500-6,500 ppm Be.(2) In 2014, twenty of 31 historic stockpiles taken from outcrop were analyzed by Materion using a lab-based berylometer(3), with results showing a range from 770-3,216 ppm Be and a weighted average of 1,741 ppm Be(4). Most recently the Company conducted new sampling of all 31 stockpiles and of similar outcrops on the property (see news release, August 6, 2025). These samples were submitted for analysis and details of the sampling and results will be provided in the coming weeks.

President Rascan further comments, "Our recent completion of sampling and mapping at Claybank, Beryllium Butte and Meteor Projects in Utah confirm our intent to contribute to the future development and production of this strategic and critical mineral."

Additional Utah Beryllium Projects

Beryllium Butte - Initially referred to as Lithium Butte, Beryllium Butte is in the Honeycomb Hills located 50km 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, August 4, 2022). Follow-up channel sampling along strike averaged 1,142 ppm Be over 25.5m, with a higher-grade portion returning 2,423 ppm Be over 6.13m (see news release November 2, 2023). For contrast, Spor Mountain ore is presently mined by the world's largest producer of beryllium (Materion Corp. - MTRN, NYSE) at an average grade of 2,460 ppm Be(5). Beryllium Butte is permitted for drilling through the US Bureau of Reclamation with the intent to drill later this year.

Meteor - Located 70km west of the Materion pits along a well-maintained gravel road, Meteor is the latest addition to the Rockland beryllium portfolio. This property includes historic mines and prospects focused on tungsten with beryl also reported in zoned pegmatites.(6,7) Most of the world occurrences of beryl are in zoned pegmatites, with larger crystals near the center and smaller crystals at the margins. It also preferentially occurs with tungsten (as scheelite).(3) Additional reconnaissance and sampling is planned at Meteor by the Company, and the State of Utah Department of Natural Resources has also expressed an interest in visiting the property.

Arrangement with MiRESSO

Through its Technical Advisor Mr. Chris Dorn, the Company has an informal arrangement with MiRESSO(8), a fusion-focused company, which is a spin-off from the National Institutes for Quantum Science and Technology (QST) in Japan. Rockland will provide Be-bearing rock samples for testing to MiRESSO (see news release April 11, 2025), who are engaged in the construction of an energy-efficient, low-temperature process for the extraction of beryllium from beryl. MiRESSO has also expressed interest in testing bertrandite for Be recovery, and samples will also be provided to the MiRESSO team.

Arrangement with Mithril Mining

Rockland was fortunate to add Mr. Taylor Sulik as a Technical Advisor just as it acquired the Meteor claims. Mr. Sulik is president of Mithril Mining Corporation(9), which is focused on reshoring extraction and processing of US-based deposits of critical minerals, to include tungsten and beryllium. 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 center for the Great Basin of Utah and Nevada. The facility has power and water in place and is located approximately 40 kilometers north of the Meteor property. Rockland and Mithril have engaged in informal conversations that will provide expertise in processing techniques for beryllium and other critical mineral deposits in the Great Basin.

About Beryllium

Beryllium is a high-value, essential, light metal with wide applications in the aerospace, computer, telecommunications, electronics, medical, satellite, clean energy, and defense sectors. Anticipated future needs for beryllium, as well the limitation in having only a single source for US domestic use, places beryllium as both a critical and a strategic mineral according to US government sources(10).
