Onyx Gold Stock Price, News & Analysis

Onyx Gold Corp. (OTCQX: ONXGF; TSXV: ONYX) is a Canadian gold exploration company focused on district-scale opportunities in established mining jurisdictions. The company is active in the gold ore mining industry and concentrates its efforts on projects in Timmins, Ontario, and Yukon Territory, targeting large, structurally controlled gold systems.

According to company disclosures, Onyx Gold’s flagship asset is the Munro-Croesus Project, a 100%-owned land package located approximately 75 km east of Timmins, Ontario, along Highway 101 in the heart of the Abitibi greenstone belt, described as Canada’s premier gold mining jurisdiction. The project covers about 109 km² of prospective geology within the influence of major gold-bearing structural breaks, including the regional Pipestone Fault and related structures. The land package includes the past-producing Croesus Gold Mine, which is noted for having yielded some of the highest-grade gold ever mined in Ontario, and has been consolidated through extensive acquisition of patented and unpatented mining claims between 2020 and 2025.

Core exploration focus and Argus discoveries

Onyx Gold reports that its current exploration is centered on a series of discoveries at Munro-Croesus known as the Argus North, Argus Main, and Argus West zones. These zones are described as broad, structurally controlled gold systems hosted mainly in mafic variolitic volcanic rocks and associated volcanic breccias, with mineralization influenced by northeast-trending faults and the proximity to the Pipestone Fault corridor.

The company states that drilling at Argus North has outlined wide intervals of +1 g/t gold mineralization containing multiple continuous higher-grade sub-intervals. Reported examples include intersections such as 208 m grading 2.3 g/t gold in hole MC25-232 and 194 m grading 1.8 g/t gold in hole MC25-233, with numerous higher-grade internal zones. Additional results cited by the company include intersections like 99.5 m grading 1.5 g/t gold in hole MC25-195 and 71.0 m grading 1.3 g/t gold in hole MC25-197. Step-out drilling and surface work have traced mineralization from surface to depths exceeding 350–400 m, with the system described as remaining open along strike, down-dip, and down-plunge.

At Argus Main, located roughly 100 m south of Argus North, Onyx Gold describes a near-surface, bulk-tonnage style target over an approximate 750–800 m by 200 m footprint. Company results highlight broad zones of near-surface gold mineralization with localized higher-grade sub-intervals, such as tens of metres grading around 0.3–0.6 g/t gold with internal intervals above 1 g/t gold. The Argus Main zone is interpreted to be influenced by the Pipestone Fault corridor and associated silicified mafic volcanic flows cut by pyritic veinlets.

The Argus West area, about 250–430 m southwest of Argus North along the Argus Fault, is described as a newer discovery. Onyx Gold reports near-surface intersections such as 21.2 m grading 2.1 g/t gold, including 14.0 m grading 3.0 g/t gold and 1.0 m grading 19.7 g/t gold with visible gold, as well as additional intervals like 26.2 m grading 1.2 g/t gold and 5.0 m grading 5.1 g/t gold. These results support the company’s interpretation of a broader, structurally controlled corridor hosting multiple mineralized zones.

Munro-Croesus Project setting and geology

Company materials describe the Munro-Croesus Project as benefiting from road access and existing logging roads, with gold mineralization located beneath or adjacent to these access routes and within a few kilometres of Highway 101. The project sits within the Abitibi greenstone belt and is influenced by regional structures such as the Pipestone Fault, the Munro Fault, and the Porcupine-Destor Fault Zone. Onyx Gold notes that its land consolidation has unified a patchwork of claims around the historic Croesus Mine into a single coherent exploration package.

Gold at Argus North and related zones is reported to be associated with strong albitization and silicification, pyritic stringers, and localized porphyritic intrusions within variolitic basalts and volcanic breccias, commonly cut by dominant steeply dipping, northeast-trending faults and associated fractures. The company interprets this combination of alteration, brecciation (including hyaloclastic, crackle, jigsaw, and polylithic breccias), and structural preparation as key controls on gold deposition. At surface, mechanized stripping and channel sampling have exposed alternating massive, variolitic, fragmental, and pillowed basalts intruded by feldspar porphyry dykes, with mineralization hosted primarily in fragmental basalt units.

C Zone and additional targets at Munro-Croesus

Beyond the Argus trend, Onyx Gold reports work at the C Zone, a regional target approximately six kilometres east of Argus North and three kilometres northeast of the historic Croesus Mine. Surface trenching and channel sampling at the C Zone have returned high-grade assays, including 39.5 g/t gold over 2.3 m with a sub-interval of 124 g/t gold over 0.62 m. The company interprets the C Zone as a newly exposed vein zone with possible similarities to the Croesus-style high-grade veins, hosted in pillowed mafic volcanics within a brittle deformation zone and characterized by quartz-carbonate veins and stockworks, strong carbonatization, sericite and silica alteration, and sulphide minerals such as arsenopyrite and pyrite, with occurrences of visible gold.

Onyx Gold indicates that the Munro-Croesus property also includes other targets such as the GM Vein, Croesus Flow shoots, Lalonde quartz-carbonate vein targets, and the Flipper Zone, where historical drilling reported broad zones of mineralization in Porcupine sediments. The company’s disclosed drill plans allocate significant meterage to testing a multi-kilometre trend of underexplored mafic variolitic basalts that host Argus North and Argus Main, as well as additional structures and intrusive-related targets along the Pipestone Fault and related corridors.

Other Ontario projects: Golden Mile and Timmins South

In addition to Munro-Croesus, Onyx Gold describes two large, early-stage projects in the greater Timmins gold camp:

• Golden Mile: A roughly 140 km² property situated about 9 km from Newmont’s Hoyle Pond Mine in the Timmins area. Company descriptions present Golden Mile as an earlier-stage exploration property with potential related to its proximity to known multi-million-ounce deposits.
• Timmins South: A land package of approximately 187 km² located to the south and southeast of Timmins, positioned around the Shaw Dome structure. Onyx Gold characterizes Timmins South as offering significant discovery potential based on its structural setting.

These projects are portrayed as part of a broader portfolio strategy in the Timmins region, complementing the more advanced work at Munro-Croesus.

Yukon portfolio in the Selwyn Basin

Beyond Ontario, Onyx Gold reports that it controls four properties in Yukon’s Selwyn Basin, an area the company notes is gaining recognition due to recent gold discoveries and increasing exploration investment. The company highlights its King Tut Property, located approximately 50 km south of Snowline Gold’s Valley discovery and adjacent to Fireweed Metals’ MacPass property. These Yukon assets are described as part of a commanding land position in an emerging exploration district, though detailed drill results for these properties are not provided in the supplied materials.

Exploration programs and funding

Onyx Gold has disclosed a multi-phase drill program at Munro-Croesus. The company reports completion of a 25,000 m program and the launch of a fully funded 50,000 m Phase III drill program, for a total planned 75,000 m of drilling across Phase I/II/III. The Phase III program is described as utilizing three drill rigs and focusing on expanding Argus North, testing fault-offset blocks and new targets along the Pipestone Fault, and advancing other zones such as Argus West and regional prospects.

Company news releases state that Onyx Gold has raised significant capital through bought-deal and non-brokered private placements, with aggregate proceeds in the tens of millions of dollars, and that it maintains a strong treasury to fund ongoing exploration in Ontario and Yukon. The company emphasizes that its programs are fully funded over the disclosed planning horizon.

Corporate profile

Onyx Gold is described as being led by an experienced team with a track record in discovery, development, and value creation. The company trades on the TSX Venture Exchange under the symbol ONYX and on the OTCQX/OTCQB market in the United States under the symbol ONXGF. Its stated strategy is to create shareholder value through disciplined exploration, strategic growth, and responsible resource development in well-established Canadian mining jurisdictions.
