First Mining Further Defines Buzz Zone and North Zone
Expansion Targets at the Duparquet Gold Project
• Buzz Zone returns 1.55 g/t Au over 15.4 m including 3.08 g/t Au over 5.3 m
• North Zone returns 4.00 g/t Au over 5.7 m including 6.65 g/t Au over 2.0 m
November 21, 2024 – Vancouver, Canada – First Mining Gold Corp. (“First Mining” or the “Company”)
(TSX: FF) (OTCQX: FFMGF) (FRANKFURT: FMG) is pleased to announce new drilling results from the 2024
Phase 3 diamond drilling program a t its Duparquet Gold Project (“Duparquet Project” or the “ Project”)
located in Quebec, Canada. An additional 4,194 m has been drilled in six holes at the Buzz Zone and North
Zone targets this year in an effort to demonstrate growth opportunit ies for two priority open-ended
resource expansion targets at the Duparquet Project.
Drilling in the Buzz Zone has returned positive drill intercepts over a strike length of 170 m between the
newly drilled holes. A total of 1,875 m in three drillholes was recently completed, and highlights of this
drilling include drill hole DUP24-028 returning 1.55 g/t Au over 15.4 m (including 3.08 g/t Au over 5.3 m),
drill hole DUP24-029 returning 1.19 g/t Au over 35.3 m, and 2.63 g/t Au over 14.0 m (including 30.50 g/t
Au over 0.85 m), demonstrating both encouraging grades and widths within an area of potential resource
growth and further exploration expansion opportunities.
The Buzz Zone i s situated immediately south of the existing Duparquet Project mineral resource and is
known to occur along high strain corridors within sheared and brecciated zones that straddle or cut
through the margins of the Beattie syenite. The overall Buzz target remains under -explored and is open
both up and down-dip from the initial zone of interception and will be a focus in follow-up drill campaigns.
Further drilling at t he North Zone continues to return positive drill intercepts as First Mining tests the
mineralization strike extension eastwards and down p lunge beyond the limits of previous exploration
efforts. A total of 2,319 m was completed in three holes, supporting a 130 m strike extension towards the
east of the current resource. Highlights of the recent drilling included drill hole DUP24-032 returning 4.00
g/t Au over 5.70 m (including 6.65 g/t Au over 2.0 m) and DUP24-031 returning 1.61 g/t Au over 8.35 m,
(including 5.02 g/t Au over 1.65 m) demonstrating important grade continuity of the North Zone along
strike and down plunge.
The North Zone is situated along the northern Beattie syenite-mafic volcanic contact that is known to host
higher-grade mineralization along high strain and brecciated zones that are along interpreted splay
structures from the Destor-Porcupine Fault Zone (“DPFZ”).
“We are pleased to announce these new positive drilling results from our Phase 3 diamond drilling
program at Duparquet,” stated Dan Wilton, CEO of First Mining. “ Exploration at Duparquet is a high
priority focus for First Mining and t hese results continue to demonstrate the potential at the project
outside of our current mineral resource estimate . Our exploration programs are supported by a strong
geoscience foundation and position us well for our upcoming drill phases.”

The Phase 3 drill program commenced in May 2024 and a total of 9,564 m of drilling has been completed
to date. There are 4,557 m of outstanding results and First Mining expects to report the final results in
Q4 2024. The Phase 3 program focused on priority target s with the aim of drill testing and advancing
multiple potential resource expansion zones across the Duparquet Gold project. First Mining believes the
Buzz Zone and North Zone targets provide significant resource growth potential that will continue to
advance with additional exploration phases at the Project.
A plan map of the Buzz Zone and North Zone drill holes is presented in Figure 1, and corresponding assay
highlights are presented in Table 1, with full assay results listed in Table 2 and drill hole locations in Table

Duparquet 2024 Exploration Programs
Exploration activities have continued to advance at the Duparquet project through out 2024, with the
Phase 3 drilling and regional field work programs now winding down for the year. Inbound assay results
are being reviewed with the key focus shifting to the interpretation and integration of the 2024 data -
including geochemi cal, geophysic al, oriented core, and magnetic susceptibility data - into the 3D
geoscience models, to support the delineation of further expansion targets.
Exploration efforts are advancing with the development and review of follow -up programs for 2025,
maintaining focus on the Company’s integrated geoscience exploration strategy.
Additional Details on Buzz Target Drilling
The Buzz Zone drilling strategy is focused on targeting resource growth immediately south of the current
Duparquet mineral resource. The Buzz Zone currently spans 300 m strike and 200 m depth between drill
holes. The target remains open up - and down-dip along the core plunge of the gold mineralization. The
Buzz Zone was originally discovered during First Mining’s 2023 drilling program, with drill hole DUP23-002
intersecting 6.52 g/t Au over 4.6 m (refer to news release dated September 5, 2023).
The 2024 Buzz follow -up drilling campaign , comprising of three holes - DUP24-028, DUP24- 029, and
DUP24-030 (Figures 2 and 3), has further defined the gold zone along strike and at depth. Mineralization
in all three holes consists of fine -grained to very fine-grained disseminated pyrite mineralization,
pervasive silica and sericite alteration, and is hosted within syenite units or along syenite -argillite and
volcanic contacts. Higher-grade zones are consistent along the interpreted D2 higher strain zones, which
is characterized by strong shearing and/or brecciation observed in the core.

The 2024 drilling campaign has further defined, expanded, and delineated higher-grade trends within the
Buzz Zone and the recent drill results continue to support the area as a highly prospective target zone for
the Project, with the potential to unlock meaningful mineralization along strike as the target remains open
in all directions (Figure 4). The Buzz Zone remains a priority area for exploration and potential expansion
of the Duparquet mineral resource.

Additional Details on North Zone Drilling
The North Zone drilling strategy is focused on targeting depth and strike extensions, with an emphasis on
potential high-grade trends that support the down-plunge continuity of the mineralization. In June 2024,
First Mining announced drill results from DUP24 -024 which intersected multiple gold zones including
10.67 g/t Au over 5.3 m, 6.63 g/t Au over 9.0 m, 3.04 g/t Au over 33.5 m, and 5.97 g/t Au over 33.0 m (see
news release from June 18, 2024), and identified a newly interpreted syenite–mafic volcanic contact zone
which is strongly favourable for higher-grade gold mineralization owing to geochemical and rheological
attributes. Initial drill holes targeting the North Zone have led to an updated 3D geological interpretation,
identifying a contact zone between the mafic volcanic and syenite stratigraphy at depth. These findings
highlight significant opportunities for resource expansion along strike and depth. The second phase of drill
holes, including the holes reported in this news release, targets the strike extension of the North Zone
along the newly interpreted contact zone.
Drill holes DUP24-031 (Figure 5), DUP24-032 (Figure 6), and DUP24-033 (Figure 7) were all step-out holes
along the strike of the main projected syenite- mafic volcanic stratigraphic contact zone. All three holes
intersected this modelled stratigraphic zone which is defined by strongly foliated and/or sheared basalt
at the northern contact of the Beattie syenite unit. Hole DUP24-031 intersected strong silica- and sericite-
altered syenite with increased quartz carbonate veining and up to 5% fine grained pyrite mineralization ,
that hosted gold mineralization near the ‘contact zone’. Hole DUP24-032 intersected sheared sericite-
altered basalt with up to 10% localized , very fine -grained disseminated pyrite mineralization, in close
proximity to the contact zone. Hole DUP24-033 intersected the syenite-mafic volcanic contact zone at
depth with strongly sheared silica- and sericite -altered basalt , with mineralization hosted within the
‘contact zone’ of a 5.5 m sliver of silica-altered syenite with up to 1% fine grained pyrite mineralization.
