Star Metro - Boron One Holdings Inc. Completes Its Jarandol Basin Exploration Program for 2026

The goals of Balkan Gold's current three-year project of geological exploration of borates and related mineral resources in the Jarandol Basin (to the west and north of the Company's Piskanja borate deposit) are:

• Definition and separation of sections of the sedimentation basin that are potential carriers of genetically related raw materials (borates, magnesite, zeolites, cement marls, bentonites, etc.);

• A detailed look at the mineralization of borates in the prospective area (first discovered by the Company in 2015), and;

• The identification of potential borate mineralization in the central and western part of the exploration area.

Balkan Gold conducted the following works as part of this exploration season (2025-26), in preparation for an upcoming drilling program within the Basin:

• Geological surface mapping and construction of a detailed geological map 1:5.000: The mapping covered 6 km2 and included all the individual perspective locations in the central and western parts of the Jarandol license area

  • Within the prospective units, there was the appearance of carbonates (limestone, dolo rocks), hydrothermally altered limestones and vulcanoclastites on the surface of the terrain [these lithological units are part of productive borate mineralization]

  • 24 samples from outcrops were collected

• Geochemical soil surveying/metalometric soil sampling:
  Sampling was conducted by profiles and by grid (50x25 m)

  • Sampling occurred in 7 locations, with a total of 121 samples collected for analysis

• Trenching:
  Two trenches, each of 15 m, were prepared in order to analyze the contact point between limestone and other Miocene sediments

  • A total of 33 samples were collected for analysis

• Laboratory works:
  The laboratory analysis is currently in progress and includes:

  • Petrological and XRD research for 16 outcrop samples

  • Multi-elements and oxides analysis for 16 outcrop samples

  • Multi-elements analysis for 121 soil samples and 33 trench samples

The purpose of this field work is to help establish high value drill targets within the basin, as part of the next work phase.

"Our team continues to methodically explore the Jarandol Basin in order to help maximize the data derived from our next drill program," said Tim Daniels, President of Boron One. "We believe the Jarandol Basin has good potential to add to the known boron resources in the area, and we look forward to continuing to develop the Basin along with our flagship Piskanja Project located adjacent."

Previous exploration by Balkan Gold has shown that the Jarandol Basin has the potential to host extensions to the Company's Piskanja boron deposit and/or to the Pobrdje boron mine (located 2.5 km away on the other extremity of the basin), as both of these deposits remain unbounded towards the center of the Basin. In addition, the Basin holds the potential to host additional, unrelated boron deposits. In a previous drill program conducted by Balkan Gold, at a location in the Basin approximately midway between the Piskanja and Pobrdje deposits, 6 exploratory drill holes returned occurrences of borates. Three of the six drill holes intersected occurrences of borates that exceed the Company's economic criteria for grade and thickness. Two of the six drill holes intersected one boron layer of potential economic grade and thickness, while a third drill hole intersected two distinct prospective boron layers. Mineralized intervals included one intersection of 1.88 meters averaging 41.33% B2O3, a second intersection of 1.3 meters averaging 41.88% B2O3, and a third intersection of 1.75 meters averaging 39.71% B2O3 (as previously reported by the Company in a news release on December 22, 2015).

About the Jarandol Basin Project
The Jarandol Exploration License (received in April of 2024 and valid for 3 years) covers 21.03 km2, and is extendable up to a total of 8 years, subject to Serbian mining regulations. The Jarandol Basin License contains all the land within the basin which is prospective for boron, including the territory directly adjacent to, and in between, the Company's 100% owned Piskanja Boron Project on the eastern edge of the basin, and the government owned Pobrdje Boron Mine, located 2.5 km away from Piskanja on the opposite edge of the basin.

The Jarandol Basin is a Miocene age tertiary deposit located within the Vardar Belt of Neogene lacustrine deposits of evaporates. The Vardar Belt contains the world's richest borate deposits, including those found in Turkey, which are of similar genesis to the Serbia borate deposits.

The Jarandol Basin is a well-known, historical mining district in southern Serbia which hosts two known boron deposits, and an operating coal mine. The Basin contains excellent infrastructure for mining (having hosted mining operations continuously for more than 100 years) including paved roads, rail, power, experienced miners, and sufficient support industries, located 250 km south of Belgrade by all season, paved roads.

On behalf of the Board of Directors,
