Bronco Resources Provides Exploration Update at Placer Mountain Gold Project

April 2 2026 TSX-V:BRON

BRONCO RESOURCES CORP. (TSX -V:BRON) (“ Bronco” or the “ Company”), is pleased to

present the following exploration update and summary of recently completed work at its

Placer Mountain Gold Project, located in the Similkameen Mining District, near Princeton, BC.

Bronco personnel recently mobilized to the drill core location , where the core has been

securely stored since 2021. The drill core from Kodiak Zone was physically rehandled and

relogged by company geologists, with a focus on defining coherent alteration domains and

establishing systematic spatial relationships to mineralized quartz veins and structures.

Magnetic susceptibility measurements were completed at regular 25 cm intervals along the

entire length of all drill core from Kodiak Zone, for a total of 7,311 individual measurements. The

data were collected with a KT-10 handheld magnetic susceptibility reader, providing a

continuous, quantitative dataset to support ongoing interpretation and targeting efforts.

The host rock at the Kodiak Zone is a relatively fresh, mafic, equigranular diorite which

contains abundant primary magnetite as a rock forming mineral. The observed magnetic

susceptibility trends in the data shows a systematic progression from higher values (20 – 60 x

10⁻³ SI) within the fresh intrusive phase, reflecting intact primary magnetite, to lower values, in

wall rock where magnetite has been removed by hydrothermal alteration.

It was also observed that in proximity to quartz veins , the intrusive wall rock is variably

silicified and sericitized, yet remains structurally coherent. The wall rock near quartz veins is

pervasively magnetite depleted, becoming effectively non-magnetic (0.01 – 0.5 x 10⁻³ SI).

This characterization has allowed separation of the intrusive host into various coherent

magnetic subdomains. The domains are listed in the following table.

The separation of vein and host rock into systematic alteration domains has allowed company

geologist to further their targeting efforts, and create alteration zonation maps, seen below.

Next Steps

Low magnetic t rends in the data show correlation to prior drilled mineralized quartz

intercepts. The zones of magnetite degradation in the diorite represent a larger spatial footprint

than previously recognized. This greatly increases the potential target area at Kodiak Zone.

Magnetic alteration extends west, east, and north of known mineralization . An additional

completely untested region, the Grizzle Target (Figure 6, below), remains for follow up in 2026.

A newly identified area of note, the Eastern Palace Target, has been selected for soil coverage

in 2026. The soil anomaly over the Kodiak Zone remains open to the east and south, with

samples up to 345 ppb Au in soil near the margin of the prior grid area, coincident with magnetic

alteration.

The company plans to complete its second-phase ground magnetic survey over the

aforementioned target area s. An additional airborne LiDAR survey over the entire Main

Zone – Kodiak Zone quartz corridor is under consideration, to aid in elevation control, identify

surficial geology trends, and outcrop locations.

Bronco Resources holds a current multi-year area-based (MYAB) permit for the project, with

additional drilling expected by Q3 2026.
