CEO.CA Chairman's Briefing

(TheNewswire)

April 2 2026 – TheNewswire - 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 trends 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 areas. 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.
