BORON ONE HOLDINGS INC. COMPLETES ITS JARANDOL BASIN EXPLORATION PROGRAM FOR 2026

Boron One Holdings Inc.'s wholly owned operating subsidiary, Balkan Gold d.o.o., has successfully completed all of this year's planned field exploration works on its Jarandol basin licence area in Serbia. The results have been compiled into a requisite annual report and submitted to the Ministry of Mining, satisfying the requirements for the Jarandol Exploration licence to remain in good standing.

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);

• 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 six square kilometres and included all the individual perspective locations in the central and western parts of the Jarandol licence 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 (50 by 25 metres).

• Sampling occurred in seven 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;

• Multielements and oxides analysis for 16 outcrop samples;

• Multielements analysis for 121 soil samples and 33 trench samples;

The purpose of this fieldwork 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 kilometres away on the other extremity of the basin), as both of these deposits remain unbounded toward the centre 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, six 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 metres averaging 41.33 per cent B2O3, a second intersection of 1.3 metres averaging 41.88 per cent B2O3, and a third intersection of 1.75 metres averaging 39.71 per cent B2O3 (as previously reported by the company in a news release on Dec. 22, 2015).

About the Jarandol basin project

The Jarandol exploration licence (received in April of 2024 and valid for three years) covers 21.03 km2, and is extendable up to a total of eight years, subject to Serbian mining regulations. The Jarandol basin licence 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-per-cent-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.
