TomaGold Continues to Expand Berrigan Mine at Depth with a New Major 204.25 m Intersection in the Berrigan Deep Zone

MONTRÉAL--(BUSINESS WIRE)--Jun 30, 2026--

TOMAGOLD CORPORATION (TSXV: LOT; OTCPK: TOGOF) (“ TomaGold ” or the “ Company ”) is pleased to announce assay results from the first of five extension holes, TOM-25-011EXT, completed as part of Phase 2 of its drilling program at the Berrigan Mine Project, located in the Chibougamau Mining Camp of Québec. The extension of hole TOM-25-011 was designed to test modeled conductive plates at depth within the Berrigan Deep Zone. The hole, which reached a final depth of 834.70 m, intersected a 204.25 m mineralized envelope (see Figures 1 and 2), as well as several gold- and zinc-rich lenses within the broader mineralized structure.

David Grondin, President and CEO of TomaGold, said: “The extension of hole TOM-25-011EXT, which intersected 2.05% ZnEq (0.48 g/t AuEq) over 204.25 m (including 31.31% ZnEq over 2.40 m), has confirmed the continuity and extent of the Berrigan Deep mineralized system following its discovery by hole TOM-25-015 in December last year, which returned 5.08% ZnEq (1.19 g/t AuEq) over 98.50 m (including 23.20% ZnEq over 4.90 m). The interception of a mineralized envelope spanning more than 224 metres underscores the scale of this hydrothermal system. Beyond the high-grade zones already delineated in its upper portion, this broad mineralized interval at depth demonstrates the persistence of mineralization and increases our confidence in the system’s potential for further expansion. These results support the continuation of exploration, drilling and geological modelling activities across the project.”

The Company is also encouraged by the consistent mineralization observed in drill core recovered from the four remaining extension holes, TOM-25-009EXT, TOM-25-010EXT, TOM-25-012EXT and TOM-25-013EXT. Samples have been prepared and submitted for laboratory analysis, with complete assay results expected over the coming weeks.

Geological Context and District-Scale Potential

The results from hole TOM-25-011EXT further validate the Company's geological interpretation of the Berrigan Deep Zone, confirming a deeply rooted polymetallic hydrothermal system (zinc, gold, silver and copper) beneath the historic Berrigan Mine.

Lithological and structural controls: The 204.25-metre mineralized envelope intersects a sequence of ultramafic to mafic rocks composed primarily of alternating serpentinitized peridotites, komatiites, pyroxenites and gabbros. Technical data indicate that the mineralization is strongly controlled by regional structures. It is concentrated along shear zones and is localized within contact breccias between different lithological units, which act as physical barriers favouring the accumulation of mineralizing fluids.

Mineralization styles and geochemical signature: Mineralization at Berrigan Deep is characterized by host-rock replacement and occurs as stockwork vein and veinlet networks, sheared undulating veins, and coarse semi-massive to massive sulphide masses. The sulphide assemblage is dominated by abundant sphalerite (zinc) and pyrrhotite.

Detailed analysis of the drilling data reveals a distinctive metallogenic signature. Although copper (in the form of chalcopyrite) represents a relatively minor component of the overall mineralized envelope, it exhibits a spatial correlation with higher gold grades. For example, the interval that returned 5.89 g/t Au (31.31% ZnEq) is directly associated with a copper peak of 1.28% Cu. This geochemical correlation suggests the presence of specific hydrothermal conduits or a distinct, higher-temperature mineralizing event, opening new exploration opportunities within the system itself.

Alteration and next geophysical steps: The system reflects prolonged and recurrent hydrothermal fluid circulation, marked by pervasive alteration of the host rock that has transformed the original pyroxenites and peridotites into massive assemblages of chlorite, talc and carbonates (dolomite/calcite).

This sulphide geometry and pervasive alteration produce a distinct electrical signature. Downhole (BHEM) and surface (UTEM) geophysical surveys currently underway will enable more precise mapping of these structural conductors. These 3D vector datasets will be critical in guiding future drilling toward the core of the Berrigan Deep Zone and potentially toward additional zones of gold and copper enrichment.

About the Berrigan Mine Project

The Berrigan Mine property consists of 16 claims totalling 483 hectares located 4 km north-northwest of the town of Chibougamau. TomaGold has an option to acquire 100% of the property from Chibougamau Independent Mines Inc.

The property has been the subject of more than one historical estimate. Met-Chem Canada Inc. prepared the most recent of these in April 2001 in a report titled: “Pre-feasibility study: Etude Conceptuelle, Projects Berrigan and Tortigny” by Chuinard et al. In the report, a resource estimate completed using polygonal estimation techniques stated 1.39 Mt grading 3.17% Zn and 1.77 g/t Au on the main Berrigan Mine zone. No resource classifications were given for the resource (GM61359).

The mineral resource estimate presented above is historical in nature and was not prepared in accordance with National Instrument 43-101 standards. Accordingly, the reader is cautioned not to rely on this estimate, as the Company is not treating the estimate as a current mineral resource. The qualified person has not done sufficient work to make the resource current. Substantial data compilation, verification, and, potentially, additional drilling and resampling would be required by a qualified person before the historical estimate could be classified as a current mineral resource. There can be no assurance that any portion of the historical mineral resource will ultimately be confirmed or demonstrated to be economically viable. For further information regarding the Berrigan Mine Project, please consult the press release dated September 13, 2023.

Technical Disclosure

The drilling program was managed by Explo-Logik of Val-d’Or, Québec. Drill core was split in half, with one half submitted to AGAT Laboratories at Val-d’Or for analysis. Gold was analyzed by fire assay (50 g) with atomic absorption finish, while base metals were analyzed by four-acid digestion with ICP-OES finish. Samples with gold grades greater than 10 g/t are reprocessed using metallic screening with a 106 µm cutoff. The processed material is split and analyzed by fire assay with ICP-OES finish to extinction. A separate split is prepared to independently analyze mineralized intervals with a target grade greater than 1.00% Cu-Zn using a Na₂O₂ fusion with ICP-OES or ICP-MS finish. Sample preparation duplicates, certified reference standards, and blanks are inserted into the sample stream.

ROME (AP) — Pope Leo XIV on Tuesday begged a breakaway group of traditionalist Catholics to call off its plan to consecrate new bishops without his consent, calling the move a schismatic act and a “sin of extreme gravity.”

“I plead with you and ask you with all my heart: please turn back!” Leo wrote in a letter to the Rev. Davide Pagliarani, the superior of the Society of St. Pius X.

Leo issued the last-ditch appeal a day before the society plans to consecrate four new bishops at its seminary in Econe, Switzerland. Under church law, the consecrations constitute a schismatic act, or an intentional rupture of the unity of the Catholic Church, and incur automatic excommunication for the four bishops and the bishop administering the consecration.

In response to the pope’s letter, Marc-André Mabillard, media manager for the society, expressed “great sadness to not be understood by our leader,” and added: “We are changing absolutely nothing in our plans.”

Asked by phone about the prospect of excommunication, Mabillard said: “We don’t fear it. It pains us immensely, but we believe that the good we seek is greater than the pain that will be inflicted upon us.”

The ceremony poses the first major crisis for the American pope, who has stressed the need for church unity since the start of his pontificate. He has worked especially hard to heal tensions with traditionalist Catholics who prefer the old Latin Mass, that worsened in some ways during the Pope Francis pontificate.

The society was founded in opposition to the modernizing reforms of the 1960s Second Vatican Council. Among other things, the council revolutionized the Catholic Church’s relations with other religions and the laity, and allowed Mass to be celebrated in vernacular languages rather than Latin.

Its members celebrate the ancient Latin Mass and have accused the modern church of being rife with heresies and errors. The society insists that only the SSPX is upholding the true faith of Christ and has justified the consecrations, citing a “state of necessity” to minister to its faithful.

In 1988, SSPX founder Archbishop Marcel Lefebvre consecrated four bishops without papal consent. The Vatican promptly excommunicated Lefebvre and the four other bishops, and the group today still has no legal status in the church.

The Vatican in 2009 lifted those original excommunications as part of its outreach to try to bring the group back under its wing. But the Vatican has warned that a similar fate awaits the new bishops if Wednesday's consecrations go ahead.

In his letter, Leo repeated the Vatican's offer of dialogue and said that going through with the consecrations would be counterproductive for the SSPX faithful.

“I urge you to consider carefully the spiritual good of the faithful, because the schismatic act you are about to undertake would deprive them of the licit, and in some cases, even valid reception of the sacraments,” he wrote.

Despite the original 1988 schismatic act, the group has continued to grow and today poses a threat to the Holy See as a parallel, ultra-Catholic, pre-Vatican II church. The SSPX counts two bishops, 751 priests, 264 seminarians, 145 religious brothers, 88 oblates and 250 religious sisters representing 50 nationalities, according to SSPX statistics.
