TOMAGOLD CONFIRMS LATERAL CONTINUITY OF THE BERRIGAN DEEP ZONE OVER MORE THAN 250 METRES WITH EXTENSION HOLE TOM-25-009EXT

TomaGold Corp. has released assay results from the extension of drill hole TOM-25-009 (TOM-25-009EXT), completed as part of phase 2 of its drilling program at the Berrigan mine project, located in the Chibougamau mining camp in Quebec.

Highlights:

• Significant mineralized intersections: Drill hole TOM-25-009EXT intersected multiple zinc-, gold-, silver- and copper-rich mineralized intervals at depths between 389.35 metres and 530.35 metres, including:
  • 29.90 m grading 2.24 per cent zinc equivalent (0.52 gram per tonne gold equivalent) from 469.25 m to 499.15 m, including 1.75 m at 8.03 per cent ZnEq, 2.60 m at 7.32 per cent ZnEq and 1.55 m at 6.45 per cent ZnEq;
  • 13.75 m grading 1.83 per cent ZnEq (0.43 g/t AuEq) from 395.20 m to 408.95 m, including 1.00 m at 6.18 per cent ZnEq;
  • 4.35 m grading 2.46 per cent ZnEq (0.58 g/t AuEq) from 526.00 m to 530.35 m, including 0.90 m at 8.87 per cent ZnEq.
• Lateral continuity confirmed over more than 250 metres: Drill hole TOM-25-009EXT fills a strategic gap between discovery hole TOM-25-015 (5.08 per cent ZnEq over 98.50 m) and the recently reported TOM-25-011EXT (2.05 per cent ZnEq over 204.25 m), confirming the lateral continuity of the Berrigan Deep zone over more than 250 metres.
• Results pending for holes TOM-25-010EXT, TOM-25-012EXT and TOM-25-013EXT: Mineralization has been consistently observed in the drill core recovered from all three other extension holes, with assay results still pending.
• Geophysical model validation: The extension of drill hole TOM-25-009 (TOM-25-009EXT), extended to a final depth of 621 m, successfully intersected the upper portion of the modelled conductive plate. These results confirm the three-dimensional accuracy of the geological model.

This drill hole was specifically designed to test the upper portion of the conductive plate modelled at depth. Originally terminated at 276 m during phase 1, the hole was extended by an additional 345 m to a final depth of 621 m. It intersected a lithological sequence dominated by altered pyroxenites and peridotites, confirming the presence of a significant polymetallic hydrothermal system.

David Grondin, president and chief executive officer of TomaGold, said: "The results from extension hole TOM-25-009EXT fully validate our geophysical model. Following the initial discovery in drill hole TOM-25-015 and the extensive 204-metre mineralized envelope recently reported in drill hole TOM-25-011EXT, this latest hole demonstrates that the upper portion of the conductive plate is also strongly mineralized. These results confirm the excellent vertical and lateral continuity of the Berrigan Deep zone, which now extends over more than 250 metres in length. The consistent presence of robust grades further strengthens our confidence in the continuity of this structure at depth and in the large-scale growth potential of the Berrigan project."

The company is also encouraged by the consistent mineralization observed in the drill core recovered from the three remaining extension holes: TOM-25-010EXT, TOM-25-012EXT and TOM-25-013EXT, for which assay results are still pending.

Geological context and district-scale potential

The data from the extension of drill hole TOM-25-009 further support the model of a large hydrothermal system extending at depth:

• Host lithologies: The mineralized intersection cuts an ultramafic to mafic sequence consisting of alternating pyroxenites and peridotites, lithologies that have proven to be excellent hosts for mineralization at Berrigan.
• Mineralization signature: From 389.35 m to 530.35 m, the mineralization is characterized by lenses and clusters of sulphides (locally reaching up to 50 per cent dominated by pyrrhotite and sphalerite, with chalcopyrite also present). Notably, these sulphides are closely associated with an intense system of blue quartz and carbonate veins and veinlets, indicating high-temperature hydrothermal fluid circulation.
• Structural controls and alteration: Mineralization is preferentially concentrated within sheared and brecciated zones that served as conduits for hydrothermal fluids. This strong structural permeability is accompanied by intense and pervasive alteration (carbonatization, chloritization and talc alteration), demonstrating the persistence and intensity of the Berrigan Deep hydrothermal system.

About the Berrigan mine project

The Berrigan mine property consists of 16 claims totalling 483 hectares located four kilometres north-northwest of the town of Chibougamau. TomaGold has an option to acquire 100 per cent 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 million tonnes grading 3.17 per cent zinc and 1.77 grams per tonne gold 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 Sept. 13, 2023.

Technical disclosure

The drilling program was managed by Explo-Logik of Val d'Or, Que. 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 grams) with atomic absorption finish, while base metals were analyzed by four-acid digestion with ICP-OES finish. Samples with gold grades greater than 10 grams per tonne are reprocessed using metallic screening with a 106-micrometre cut-off. 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 per cent copper-zinc using a sodium peroxide (Na2O2) fusion with ICP-OES or ICP-MS finish. Sample preparation duplicates, certified reference standards and blanks are inserted into the sample stream.

The technical content of this press release has been reviewed by Jean Lafleur, PGeo, vice-president of exploration of the company, and Suzie Tremblay, PGeo, vice-president of operations at Explo-Logik Inc. and a consultant to TomaGold, each of whom is a qualified person as defined under NI 43-101. Mr. Lafleur has approved the technical content of this press release.
