NEWS RELEASE
Bronco Resources Expands High Grade Gold Mineralization Along Strike & In
Parallel Zones
February 28, 2025 TSX-V: BRON
BRONCO RESOURCES CORP. (TSX -V:BRON) ( “Bronco” or the “Company”) is pleased to
announce the expan sion of high grade mineralization at the Company’s Placer Mountain
project in Southern BC (“Placer Mountain” or the “Property”). Drilling expanded high grade
gold mineralization at the Kodiak Zone by 200m along and 200m parallel to strike (Figures 1
& 2). The Kodiak Zone now has a drilled mineralized footprint of 330 by 300 metres. KZ-24-
10 intersected 16.05m of 2.21 g/t Au including 2.85m of 10.55 g/t Au1. In total some 1,236
meters of drilling were completed in 10 diamond drill holes and every hole hit significant gold
mineralization (Table 1 & 2). The 2024 drilling was all within the large 1.5km by 800m Kodiak
Zone gold-in-soil anomaly first discovered in 2021.
Highlights:
• Key Intersetions:
o Hole KZ-24-08 - 0.80m of 36.40 g/t gold1
o Hole KZ-24-10 - 16.05m of 2.21 g/t gold, including 2.85m of 10.55 g/t
gold1
o Hole KZ-24-09 - 13.10m of 2.28 g/t gold and 1.20m of 14.60 g/t gold1
o Hole KZ-24-04 - 22.20m of 0.79 g/t gold1
o Hole KZ-24-05 - 18.30m of 0.83 g/t gold1
• The strike of the Kodiak Zone is now 330m, expanded by 200m, to the south west
with near surface high grade gold mineralization encountered in step out holes KZ-24-
08, KZ-24-09, and KZ-24-10 (Table 1, Figure 1 & 2).
• Mineralization at the Kodiak Zone has only been tested to a true depth of 100m leaving
the system wide open at depth.
• Parallel high grade gold vein systems were encountered in 4 holes (KZ-24-04, KZ-24-
05, KZ-24-06, KZ-24-07) and 200 metres to the south east of the main Kodiak Zone
(Table 1).
• All 18 holes and 1,962m drilled in 2024 and 2021 encountered gold mineralization
within the Kodiak Zone.
• Drilling has only loosely tested ~20% of strike within the Kodiak Zone 1.5km by 800m
gold-in-soil anomaly.
• Note: all intersections are down hole widths as true width remains unknown at this
time.
Corbin Stewart, CEO, commented “ The winter 2024 drilling program was very encouraging
as we were able to confirm and significantly expand the size of the Kodiak Zone . We were
able build on the consistency and repeatability of high tenor gold mineralization with a limited

amount of drilling. In a testament to our team and contractors, all holes drilled so far in the
Kodiak Zone have encountered strong gold mineralization within multiple mineralized
systems. Our largest step out to date, KZ-24-09, which was a 200m step out , contained
multiple high grade mineralized zones corresponding to anomalous gold -in-soil. Drilling has
barely scratched the surface on the 1.5km by 800m gold-in-soil anomaly and we are excited
about the ongoing potential in the Kodiak Zone. The Kodiak Zone is just one of 8 gold-in-soil
anomalies, including the Main Vein, hosted at Placer Mountain.
We are currently using the new data to update our geological model to optimize future drilling
on the Kodiak Zone. The property has excellent infrastructure with logging road s and can be
worked year round making it a prime candidate for a large , low cos t, grid based drilling
project. In addition to infrastructure, the proximity to Princeton, BC , a full service mining
town, is extremely helpful for advancing the project going forward. The company plans to
continue to focus on drilling the Kodiak Zone as well as using our past success with
geochemical sampling to further explore the Placer Mountain property.”
2025 Exploration Planning
The company is currently planning a larger methodical grid drilling program to continue to
test the the large Kodiak Zone gold-in-soil anomaly. Planned drilling will continue to test the
Kodiak Zone along strike as well as potential parallel zones utilizing the strong correlation
between drill results and overlaying of gold-in-soil geochemistry and in -situ bedrock
mineralization. The Kodiak Zone is a n ideal candidate for a large -scale low cost grid based
drilling program due to the network of well maintained logging roads and limited tree cover.
Geochemical and prospecting field program planning is underway to better define 6 of the 8
gold-in-soil anomalies that have not been drill tested . Exploration will be guided by u sing
knowledge gained from the Kodiak Zone and Main Vein . The Company will continue to test
the potential for mineralization under late cover and provide more information in future
updates. The Placer Mountain Property continues to be a unique opportunity within South
Central British Columbia located 15km to the south of Hudbay Minerals producing Copper
Mountain Mine and Mill2.

Kodiak Zone Summary
The Kodiak Zone is a 330m by 300m drill tested gold mineral ized zone within a 1.5 km by
800m gold-in-soil anomaly. The Kodiak Zone was first disovered in 2021 through a large
geochemical soil sampling program including 89 samples above 50 ppb and values up to
18.1 g/t Au (Figure 3)3. Trenching occurred the same year and highlighted intervals of
44.50m of 0.70 g/t Au and 8.00m of 2.56 g/t Au 1,3. In 2021, 726 metres was drilled at
the Kodiak Zone and operations were severely impacted by atomospheric rivers and large
storms. Despite our limited ability to position the drill, all holes hit gold mineralization and
the company was able to intersect 3m of 39.20 g/t Au and 80.40 g/t Ag in KZ -21-05
and 1.4m of 46.51 g/t Au and 32.2 g/t Ag in KZ-21-02 (Table 3) 1,3.
The 2024 drill program was planned to confirm and expand the 2021 program. The 2024
program expanded the Kodiak Zone to 330 by 300 metres and confirmed the presence of
parallel mineralized vein sets . All holes hit gold mineralization and 9 of 10 had intercepts
greater than 5 gram metre Au (Table 1). Gold mineralization in the Kodiak Zone is hosted in
quartz sulpide veins within intrusives and characterized by >5% sulphides.

Placer Mountain Property Wide Potential
The company so far has identified 8 gold-in-soil anomalies on the Placer Mountain Property,
with two being the Kodiak Zone and the Main Vein. The Main Vein is located 2.5km to the
southwest of the Kodiak Zone and was first discovered in 2019 (Figure 3). A total of 1,709
metres was drilled within the Main Vein between 2020 and 2021. The Main Vein has been
traced for a length of 385 metres and remains open along strike including strong gold intervals
in Table 4. Some 5 of the 8 gold-in-soil anomalies show strong similarities to the Kodiak Zone
and the Main Vein. Potential for multiple styles of mineralization is shown on the Property
with a 2km by 1.5km Cu-Mo-Au-in-soil anomaly.
