Bronco Resources Provides Exploration Update for Placer Mountain Gold Project

Princeton, BC — April 2, 2026 — Leads & Copy — Bronco Resources Corp. is advancing exploration at its Placer Mountain Gold Project in the Similkameen Mining District, near Princeton, BC. The company recently completed work focusing on defining alteration domains and spatial relationships to mineralized quartz veins and structures.

Bronco Resources Corp. (TSX-V:BRON) personnel rehandled and relogged drill core from the Kodiak Zone, which has been securely stored since 2021. Geologists focused on characterizing alteration and its relation to mineralized quartz veins.

Magnetic susceptibility measurements were taken at 25 cm intervals along the entire length of all drill core from the Kodiak Zone, totaling 7,311 measurements. A KT-10 handheld magnetic susceptibility reader was used to collect the data, providing a quantitative dataset for interpretation and targeting.

The host rock at the Kodiak Zone is a relatively fresh, mafic, equigranular diorite containing abundant primary magnetite. Magnetic susceptibility data shows a progression from higher values (20 – 60 x 10⁻³ SI) in the fresh intrusive phase, reflecting intact primary magnetite, to lower values in wall rock where magnetite has been removed by hydrothermal alteration.

The company observed that near 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.

Low magnetic trends in the data correlate with previously drilled mineralized quartz intercepts. Zones of magnetite degradation in the diorite represent a larger spatial footprint than previously recognized, which increases the potential target area at Kodiak Zone. Magnetic alteration extends west, east, and north of known mineralization.

A completely untested region, the Grizzle Target, 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.
