• Exploration Between Central Duparquet and Dumico Resource Areas Returns 1.71 g/t Au over 8.9 m, Confirming Strike Continuity
• Central Duparquet High Grade Zone Returns 2.73 g/t Au over 6.15 m, Unlocking Mineralization Potential at Depth

VANCOUVER, BC, Jan. 9, 2024 /PRNewswire/ - First Mining Gold Corp. ("First Mining" or the "Company") (TSX: FF) (OTCQX: FFMGF) (FRANKFURT: FMG) is pleased to announce the expansion of multiple gold zones from the drilling of key targets at the Duparquet Gold Project ("Duparquet Project" or the "Project") located in Quebec, Canada. First Mining has completed 17 exploration drill holes totalling 6,966 m in its 2023 exploration drilling campaign which focused on initial drill testing of key targets across the project.

A new area of mineralization continuity was identified at Central Duparquet ("Valentre Target") which returned 1.71 g/t Au over 8.9 m, including 5.11 g/t Au over 1 m, and 1.29 g/t Au over 7.6 m, including 3.3 g/t Au over 1.8 m in drill hole DUP23-006. This is an exciting target for First Mining as it demonstrates the potential continuity of mineralization between the Central Duparquet and the Dumico deposits that had never been drill tested prior to First Mining's 2023 drilling campaign.

In addition, drilling at the CDHG Zone in the area of the historical Central Duparquet development returned 1.78 g/t Au over 4 m, 2.73 g/t Au over 6.15 m, including 6.98 g/t Au over 0.7 m, and including 10.6 g/t Au over 0.65 m, in drill hole DUP23-005. These results validate the resource wireframe and support the extension of a higher-grade zone with mineralization continuity at depth.

"These latest drill holes are building momentum in the untested upside potential that the Duparquet Gold Project has to offer," stated Dan Wilton, CEO of First Mining. "With a positive PEA announced in September 2023 and continued success in our team's exploration strategy, First Mining is continuing to demonstrate the resource growth potential at this critical strategic project in the centre of the prolific Abitibi Greenstone Belt."

First Mining commenced a foundational drilling program in May 2023 with a campaign that is focusing on the advancement of newly defined targets, as well as validating and expanding on resource growth and optimization opportunities.

Results returned from the exploration drill holes are continuing to demonstrate that this project has significant potential across the wholly-owned land tenure, through the confirmation of the new zones and targets at Central Duparquet, as well as the previously announced Buzz Zone (See September 5, 2023 news release).

Drilling at Central Duparquet focused on advancing geological characterization and the understanding of a higher grade trend ("CDHG Zone") and testing its continuity at depth as well as drill testing a new target ("Valentre") that could establish continuity between the Central Duparquet and Dumico resource pit designs as defined in the 2023 PEA (Figure 1).

The CDHG Zone includes drill holes DUP23-005, DUP23-007 and DUP23-008 which were drilled to test the steep easterly plunge of the Central Duparquet mineralization below the current resource pit design. An area of anomalous gold mineralization was identified over approximately 60 metres in drill hole DUP23-005 that included intersections of 1.78 g/t Au over 4.0 m and 2.73 g/t Au over 6.15 m, including 6.98 g/t Au over 0.7 m and 10.60 g/t Au over 0.65 m. Mineralization is hosted within both the syenite and at the contact with an argillitic unit, which may represent an affinity with a shear zone. Alteration includes areas of patchy chlorite and hematite, with limited sulphide mineralization occurring throughout.

Drill hole DUP23-007 targeted and validated a depth extension of the CDHG Zone and returned 1.34 g/t Au over 4.5 m hosted within syenite, as well as 1.01 g/t Au over 3.8 m and 1.16 g/t Au over 5.1 m hosted within sheared and altered basalt units interbedded with syenites.

Drill hole DUP23-008 was focused on testing the extent of mineralization from surface and at depth, as well as the strike continuity of mineralization intercepted in DUP23-006, located 350 m to the east. Drill results for DUP23-008 returned 2.04 g/t Au over 3 m, and 2.83 g/t Au over 11 m, including 4.40 g/t Au over 3 m, and extends the mineralization which is hosted within a brecciated syenite-basalt contact with chlorite and silica alteration.

Drill holes DUP23-005, DUP23-007 and DUP23-008 were successful in confirming the depth extension of the current wireframes and interpolated block model to a depth of approximately 400 m below the surface, which supports further follow-up opportunities for unlocking higher-grade trends at depth (Figure 2).

The Valentre target is located between the Central Duparquet and Dumico resource pit shells and focuses on the possible continuity of mineralization that was historically untested due to prior ownership boundaries. First Mining's maiden hole at the Valentre target, DUP23-006, aimed to test an open exploration opportunity of 175 m between these resource areas. Significant gold mineralization was intersected in multiple intercepts along the length of DUP23-006, confirming a potential for continuity of the wireframes along strike in the area at a relatively shallow depth. The most significant intercept returned includes 2.07 g/t Au over 2.5 m located immediately to the northwest of the Dumico pit design, followed further down the hole by 1.82 g/t Au over 3.0 m. The host rock is syenite with silicification and local pyrite mineralization. The best intersection along strike and immediately below the wireframes from Central Duparquet included 1.71 g/t Au over 8.9 m, including 5.11 g/t Au over 1.0 m. This mineralization is typical of that which hosts the bulk of the current mineral resource located to the east of the Central Duparquet target, which includes a syenite-associated lath to megacrystic porphyry, with local units of gabbro. Drill hole DUP23-006 confirms that the mineralization is continuous and present in several horizons between the most easterly resource pit shells from the Duparquet Gold Project's 2023 PEA (Figure 3).

A total of 1,923 m of drilling was completed at the Central Duparquet Target in four holes. Significant assay results from the Central Duparquet target are reported in Table 2, and drill locations are provided in Table 3.

The drilling results returned from the Central Duparquet Target validate the existing resource model and support the delineation and advancement of higher-grade trends. Further drilling to demonstrate continuity along strike and at depth between the Central Duparquet and Dumico pit designs is recommended, as this area has the potential to holistically add meaningful ounces to the global Duparquet Gold Project (Figure 4).

"We are looking forward to further the assay results from our 2023 drilling campaign and launching into the next round of drill targeting for 2024, where the focus will be to further advance key targets identified through the 2023 campaign," stated James Maxwell, First Mining's Vice President of Exploration.

The 2023 drilling and field campaigns at the Duparquet Gold project have provided the First Mining exploration team with a strong foundational understanding of the geoscience, data gaps and opportunities for exploration advancement. The Company is aiming to complete its Phase 2 drilling campaign this winter while actively advancing the drilling strategy for an additional Phase 3 program alongside airborne geophysics and LiDAR survey programs in areas of opportunity for data resolution enhancement.

The Duparquet Project is geologically situated in the southern part of the Abitibi Greenstone Belt and is geographically located approximately 50 km north of the city of Rouyn-Noranda. The Duparquet Project totals ~5,800 hectares focused along an area of 19 kilometres of strike length along the prolific Destor-Porcupine Fault Zone, along with numerous mineralized splays and influential secondary lineaments. The Duparquet Project includes the past-producing Beattie, Donchester and Duquesne mines and as well as the Central Duparquet, Dumico and Pitt Gold deposits. In 2023, First Mining completed a positive Preliminary Economic Assessment (PEA) for the project that will guide phased optimization and advancement moving forward.

All sampling completed by First Mining within its exploration programs is subject to a Company standard of internal quality control and quality assurance (QA/QC) programs which include the insertion of certified reference materials, blank materials and a level of duplicate analysis. Core samples from the 2023 drilling program at Duparquet were sent to AGAT Laboratories, with sample preparation in Val d'Or and analysis in Thunder Bay, where they were processed for gold analysis by 50 gram fire assay with an atomic absorption finish. Samples from selected holes were sent to AGAT Laboratories in Calgary, Alberta, for multi-element analysis (including silver) by inductively coupled plasma (ICP) method with a four acid digest. AGAT Laboratories systems conform to requirements of ISO/IEC Standard 17025 guidelines and meets assay requirements outlined for NI 43-101.

Jeff Reinson, the Company's Chief Operating Officer, will be leaving his role at First Mining effective January 19, 2024. Following Mr. Reinson's departure, James Maxwell will assume the role of Vice President, Exploration & Project Operations, reporting directly to the CEO, and will take overall responsibility for operations at Springpole, Duparquet and the Company's other projects. In addition, Steve Lines will assume the role of Vice President, Sustainability, reporting directly to the CEO.

"We would like to thank Jeff for his service and contributions to First Mining," stated Dan Wilton, CEO of First Mining.
