Onyx Gold Corp.

Timmins South: Strategic Land in a Growing Gold Exploration Hub Onyx Gold’s 100%-owned Timmins South property covers 195 km² just south of the Dome and Pamour Mines—an area seeing renewed exploration interest. This early-stage project is part of Onyx’s 442 km² land position in the Timmins Gold Camp. Timmins South Highlights:  • Located in the heart of Canada’s top gold-producing region • Prospective for intrusion-related and orogenic gold systems • Hosts monzonite intrusions and banded iron formations associated with high-grade gold • Historical grab samples up to 766.2 g/t Au • Exploration to date includes mapping, soil sampling, and drone-based surveys Timmins is emerging as a new hotspot for discovery, with recent M&A activity and excess milling capacity ready for new feed. Onyx is positioned to capitalize—with the scale, team, and assets to lead the next wave of exploration success.

Consistency of mineralization in drill hole MC24-163 highlights the potential at Argus North. The 34.5-meter interval averaging 5.4 g/t gold in MC24-163 is characterized by consistent high- grade results across much of the section — not just isolated high-grade samples. From 265.5m to 300.0m, multiple samples returned over 1 g/t Au, including: - 76.4 g/t Au (293–294m) - 28.1 g/t Au (294–295m) - 11.2 g/t Au (269.3–270m) - 10.9 g/t Au (292–293m) The consistent grade distribution over tens of meters supports the presence of continuous gold mineralization within the zone. This discovery hole is the first to test the Argus North Zone, which remains open in all directions. Additional drilling is planned to assess continuity towards the surface and at depth, as well as along strike.

Have you seen the results that are driving the excitement around Onyx Gold? Drill hole MC24-163 at the newly discovered Argus North Zone returned some of the best early-stage gold results reported in the greater Timmins camp in recent years: * 3.4 g/t Au over 69.6m * Including 13.9 g/t Au over 9.5m * Including 38.5 g/t Au over 3.0m Visible gold was logged in core between 293.0–294.0m, which assayed 76.4 g/t Au over the 1m interval. This new zone is hosted in variolitic mafic volcanics, lies just 100m north of the main Argus Zone, and remains completely open in all directions. Follow-up drilling is planned to extend the zone towards surface and depth, as well as along strike.

The Onyx Gold team had a productive weekend at the 13th Annual Scottsdale Capital Event, where CEO Brock Colterjohn and Nicole Hoeller held 18 one-on-one meetings with investors and capital markets professionals over two days of networking and discussion. There was strong interest in Onyx Gold’s recent news release highlighting the company’s new gold discovery in Timmins and upcoming drill plans. Investors were particularly excited about the scale potential at the Munro-Croesus Project and the opportunity to advance new targets in the Timmins Gold Camp and Yukon.

Did you catch Onyx Gold’s latest drill results? This discovery is one of the strongest new gold intercepts in the Timmins Camp. The Argus North discovery at the Munro-Croesus Project delivered 3.4 g/t gold over 69.6 meters — including high-grade subzones like 13.9 g/t over 9.5 meters and 38.5 g/t over 3.0 meters. Here’s why this matters: * It’s a brand-new gold zone just 100m north of the main Argus trend. * The hole was extended onto newly optioned ground, giving Onyx full control for follow-up. * The zone is wide, continuous, high-grade — and still wide open. It’s early days, but this is the kind of intercept that can redefine the potential of a project. Onyx resumes drilling in the coming weeks. Stay tuned.

Onyx Gold Intersects 3.4 g/t Gold Over 69.6 Meters at Argus North and Expands Land Position Onyx Gold has announced a major step forward in its exploration efforts at the Munro-Croesus Project in Timmins, Ontario. New drill results from the Argus North Zone confirm the strongest mineralization encountered to date, along with a strategic land acquisition that enhances the Company’s ability to expand this promising new discovery. Highlights from the News Release: * Drill hole MC24-163 intersected: - 3.4 g/t Au over 69.6 m - Including 5.4 g/t Au over 34.5 m - Including 13.9 g/t Au over 9.5 m - Including 38.5 g/t Au over 3.0 m * This is the first drill hole into the newly discovered Argus North Zone, located 100 m north of the main Argus trend. * The Argus North Zone remains open in all directions. * A new option agreement secures a 21-hectare inholding contiguous to the Argus North discovery. * The property has never been drilled and provides direct access for follow-up exploration. “These intercepts are the most impressive mineralization we've seen on the Property to date and stand out as some of the best early-stage gold results reported in the greater Timmins camp in recent years. These results likely suggest the presence of a large, previously untapped gold system within the Munro-Croesus property, presenting a tremendous new exploration opportunity for the Company.” — Brock Colterjohn, President & CEO With the Argus North discovery showing exceptional grades and scale, and closely associated with the Pipestone Fault — a major regional structure known to host large gold deposits — Onyx is preparing for a follow-up drill program. Immediate plans include step-outs along strike and dip, as well as extending earlier holes MC23-140 and MC24-164.
