Vancouver, British Columbia–(Newsfile Corp. – September 10, 2024) – Onyx Gold Corp. (TSXV: ONYX) (OTCQX: ONXGF) (“Onyx” or the “Company“) is pleased to announce the final results from the Company’s earlier drilling campaign at its Munro-Croesus Project (“Munro-Croesus” or the “Project“) in the Timmins gold camp, Ontario (Figure 1).
Assay results from the final drill hole of the Company’s 2024 drill Program (the “Program“) returned a new wide zone of strong gold mineralization located immediately north of the main Argus Zone trend.

“We are very pleased with these results, which demonstrate the prospectivity of the Munro-Croesus Project and the underlying potential of an emerging gold deposit at the Argus Zone,” said Brock Colterjohn, President & CEO. “While still early days, it is difficult to ignore the significance of this new zone that combines higher-grades with surface bulk-mining widths and shows the system progressively getting richer as we track it to the west.”
“Those that have followed Onyx Gold and its history will be aware of management’s long-term strategy to methodically consolidate significant land positions of underexplored mining claims covering prime geological potential. It is rewarding to receive strong validation of our approach with these excellent drill results. With a tight share structure, respectable treasury, and blue-chip shareholder base, the Company and its investors are in a great position to make the most of what may be the very early stages of a potentially significant new discovery within Canada’s most prolific gold jurisdiction.”
Geological Context for Drillhole MC24-163 Intersection
Context is important when assessing early exploration results and their significance for predicting exploration upside. Key factors that influence our view on the relevance of this new intersection and the potential of the Argus zone include:
The grade x thickness profile of drill hole MC24-163 compares well against “discovery hole” intersections of known major (>2Moz) Canadian gold deposits
Association with a large and growing footprint of bulk-tonnage style gold mineralization (0.1 to >2.0 g/t over a 750m x 200m area)
Association with the regional-scale Pipestone fault that is known to be an important control on gold mineralization within the region
Proximity to multiple high-grade gold veins within the large (104 sq. km) Munro-Croesus claim block, including the past-producing bonanza-grade Croesus Mine and the newly discovered GM vein
Exceptional regional gold endowment – located in the greater Timmins mining camp that has produced close to 80Moz of gold to date, the most of any mining jurisdiction in Canada. Also, it is adjacent to several multi-million ounce deposits such as the 3.0Moz Black Fox mine complex located 4 km to the southwest and the 3.5Moz Fenn-Gb deposit located 6 km to the east1
Discussion of Results
Drill hole MC24-163 was one of five drill holes completed during the Program at the Argus Zone, a 750m x 200m near-surface bulk tonnage target located three kilometers northwest of the past-producing Croesus Gold Mine (Figure 2). It was collared 35 m north of the collar of hole MC23-140 which returned 0.96 g/t Au over 27.6 meters (Figure 3). Hole MC24-163 represents the best intersection drilled to date at the Argus Zone.
The strong mineralization intersected in MC24-163 is located immediately north of the main trend of the Argus Zone and represents an entirely new zone of high-grade mineralization. With only one drill hole testing the area to date, this new Argus North Zone remains completely unconstrained and open in all directions.
The mineralization in hole MC24-163 displays typical ‘Argus-style’ characteristics with strongly silicified mafic variolitic volcanics with 3-10% pyrite stringers and local specular hematite and higher gold grades than previously reported drill holes.
The Company is currently carrying out mechanical stripping, geological mapping and geochemical sampling in the area where the intersection in hole MC24-163 would project up-dip to surface, and where historic trenching within the same key prospective variolitic basalt units along the Pipestone Fault, suggests strong potential for the system to extend well beyond the current limit of drilling.
Recent surface grab samples collected by Company geologists at Argus West, more than 500 meters from Hole MC24-163, returned up to 2.4 g/t Au within similarly pyritized and silicifed mafic variolitic volcanics as host the Argus Zone.
Onyx is also currently evaluating prospects on the recently acquired Lalonde and Highway claims to the northeast of the Croesus mine to prioritize drill targets. The Company plans to return in Q4-2024 with a drill program to follow up on the Q1-2024 results on the Argus Zone and to continue to follow the mineralization to the west, and drill test several prospects on the Lalonde claims.

Discussion of the 2024 Spring Drill Program
A total of 25 holes (MC24-143 to 167) totaling 3,280.5 m were drilled on the Munro-Croesus Project in March and April, including twenty (20) holes totaling 1,731 m on the GM Vein and five (5) holes totaling 1,549.5 m on the Argus Zone. All assay results have now been released for the Program.
The Munro-Croesus Project
The Munro-Croesus Project is located along Highway 101 in the heart of the Abitibi greenstone belt, Canada’s premier gold mining jurisdiction (Figure 1). This large, 100% owned land package includes the past-producing Croesus Gold Mine, which yielded some of the highest-grade gold ever mined in Ontario. Extensive land consolidation from 2020-2023 has unified the patchwork of patented and unpatented mining claims surrounding the Croesus Gold Mine into one coherent package (Figure 1) and enhanced the project’s exploration potential.
The Project covers 104 km2 of highly prospective geology within the influence of major gold-bearing structural breaks. Bulk-tonnage gold deposits located in the immediate region include the Fenn-Gib gold project being developed by Mayfair Gold Corp. that contains an Indicated Resource of 3.38 Moz at 0.93 g/t Au and an Inferred Resource of 157 koz at 0.85 g/t Au, and the Tower Gold Project being developed by STLLR Gold Inc. that contains an open pit Indicated Resource of 4.46 Moz at 0.92 g/t Au and an Inferred Resource of 8.29 Moz at 1.09 g/t Au1.
About the Timmins Area Gold Properties
Onyx owns 100% of each of its three Timmins properties. The Munro-Croesus Gold Project is located approximately 75 km east of Timmins, proximal to the Porcupine-Destor and Pipestone Faults, and approximately 2 km northwest and along trend of Mayfair Gold Corp.’s multi-million-ounce Fenn-Gib gold deposit. Mining occurred intermittently at Munro-Croesus between 1915 and 1936. The Golden Mile 140 km2 property is located 9 km northeast of Newmont’s multi-million-ounce Hoyle Pond deposit in Timmins.
