Composite Score 13/25

Management Skin-in-the-Game

3/5

Brock Colterjohn (President & CEO) brings a B.Sc. in Geology plus an MBA and 12+ years in the resource sector, including equity capital-markets roles at Cormark Securities and Canaccord Genuity where he raised over C$2B for mining clients. His ownership sits at approximately 1.5% of shares outstanding. Darwin Green (Executive Chairman and Founder) holds B.Sc./M.Sc./P.Geo credentials with 20+ years of deposit discovery experience across Canada, the USA, and Latin America, and is the company's third-largest individual shareholder. Total insider ownership is approximately C$5.6M against a C$145M market cap, or roughly 3.9% — modest but not alarming for a TSXV explorer.

The standout de-risking factor is Gold Fields Limited (NYSE/JSE: GFI), one of the world's four largest gold producers (~C$20B+ market cap), which invested through its subsidiary Windfall Mining Group to acquire approximately 9.4% of Onyx in a June 2025 private placement following the Argus North discovery. Franklin Resources holds an additional 11%. Strategic investment by a producing major at the drill-results stage is a credible signal that experienced technical teams have reviewed the project and see merit.

A meaningful negative: shares outstanding grew approximately 72.3% over the prior 12 months through equity financings, indicating high dilution velocity. The warrant book — including 7.1M warrants recently amended from C$0.75 to C$0.30 — adds modest near-term dilution pressure. CEO ownership at 1.5% is lower than preferred under the Framework; ideally management skin-in-the-game exceeds 5% for a 3/5 score, but Gold Fields' institutional endorsement partially compensates.

Project Geology Quality

2/5

Resource classification: NO formal NI 43-101 mineral resource estimate exists for any Onyx property. The company is in an active drill-discovery phase. The Munro-Croesus Project, located along Highway 101 in the Abitibi Greenstone Belt (Timmins Gold Camp), includes the past-producing Croesus Gold Mine — historically one of the highest-grade gold producers in Ontario — within a 100%-owned, consolidated land package. No NI 43-101 resource estimate has been filed on SEDAR+; no economic study (PEA, PFS, or FS) exists.

Drill results from the Phase I/II/III program (75,000m total; ~35,000m and 100 holes completed as of January 2026) suggest a bulk-tonnage system is developing: Argus Zone 1.87 g/t Au over 48.1m; Argus North 3.4 g/t Au over 69.6m (incl. 13.9 g/t over 9.5m) and 1.8 g/t Au over 91.0m (incl. 5.3 g/t Au over 17.0m); additional intercepts of 1.3 g/t over 77.2m, 1.2 g/t over 99.5m, and 2.2 g/t over 52.2m. A separate GM Vein is returning high-grade visible-gold results. The Abitibi geology is a Tier-1 setting and the scale of the emerging system is encouraging.

Framework note: Rubric scoring is 1/5 for 'drill results only, no resource estimate.' A score of 2/5 is applied here because the Abitibi jurisdiction is among the world's lowest geological-risk environments, the property has a documented historical production record, and drill intercepts across multiple zones indicate meaningful gold endowment rather than isolated narrow veins. However, until a QP-certified NI 43-101 resource estimate is filed on SEDAR+, the geology factor cannot score higher.

Capital Structure Health

3/5

As of October 2025: 85,152,179 shares issued and outstanding; 91,075,508 fully diluted (4,198,333 options + 1,724,996 RSUs). Cash: C$12.2M; debt: C$215,616; net cash C$11.98M (C$0.17/share). Current ratio: 29.7x. The balance sheet is clean with negligible debt.

The 75,000m drill program is fully funded from existing cash. However, the share count grew approximately 72.3% over the prior 12 months through equity financings — reflecting the typical TSXV junior pattern of raising capital to fund exploration. Warrant amendments in January 2025 moved 7.1M warrants from C$0.75 to C$0.30 exercise price, which are now near or in the money at C$1.70 and represent modest incremental dilution on exercise. Institutional support from Gold Fields and Franklin Resources facilitates future equity raises.

The capital score of 3/5 reflects a clean near-term balance sheet and fully funded program, tempered by the aggressive historical dilution rate and certainty of further equity financings to fund the remaining 40,000m of drilling and eventual resource estimation work. The company has no revenue and will continue to be a net consumer of capital for the foreseeable future.

Catalyst Proximity

4/5

The ongoing 75,000m Phase I/II/III drill program at Munro-Croesus is the primary catalyst engine — with ~35,000m complete and ~40,000m remaining, the company is releasing assay results regularly throughout 2026. Multiple zones (Argus Main, Argus North, GM Vein, and new targets up to 525m west of Argus North) are being tested simultaneously with two drill rigs, creating a pipeline of newsflow.

The most anticipated near-term catalyst is the maiden NI 43-101 mineral resource estimate, which will be triggered once sufficient drill coverage exists — likely H2 2026 or early 2027, depending on program completion and QP turnaround. Analyst consensus price targets of C$3.20-C$3.35 per share (vs. C$1.70 current) are predicated on a successful resource conversion. Gold Fields' 9.4% stake also creates optionality for an earn-in or corporate transaction as the resource picture clarifies.

A modest risk: the Phase I/II/III program has grown from an initial 3,000m (Spring 2024) to 75,000m, meaning the deposit is likely larger than initially thought — but scale requires more capital and time before a resource estimate can be published.

Comparable Acquisition Value

1/5

With no NI 43-101 mineral resource estimate and no economic study (PEA, PFS, or FS) on file, there is no valid basis for calculating a net asset value (NAV) per share or an EV/oz comparison. All valuation at this stage is speculative and driven by exploration optionality.

The C$145M market cap and C$133M enterprise value (net of cash) imply a significant premium to zero proven ounces — reflecting the market pricing in the probability of a large discovery in the Abitibi. Comparable junior explorers at the pre-resource stage in Abitibi with multi-million-metre programs and major-producer backing have traded at similar market caps, but the risk profile is categorically different from developers with defined resources.

Framework score: 1/5. This is not a criticism of the project's potential — the drill results are genuinely compelling — but the Framework is disciplined: without a resource estimate, the acquisition value factor cannot be meaningfully scored. Investors should revisit this factor after a maiden resource estimate is published.

Analyst Summary

Onyx Gold Corp (TSXV: ONYX) earns a WATCH verdict with a composite score of 13/25. The strongest factors are catalyst momentum and the strategic endorsement of Gold Fields (9.4%), one of the world's largest gold producers, which invested following the high-grade Argus North discovery in Timmins' Abitibi Greenstone Belt. Drill intercepts across Argus Zone, Argus North, and the GM Vein are wide, with meaningful high-grade cores — the emerging bulk-tonnage profile is consistent with the deposit styles that attract M&A interest in the Abitibi.

The primary weaknesses are the absence of any NI 43-101 mineral resource estimate (drill results only — no ounces, no economic study, no NAV basis) and the 72.3% share dilution over the past year. At C$145M market cap, investors are paying entirely for exploration optionality in a world-class jurisdiction. The acquisition value factor scores 1/5 by necessity — no resource means no P/NAV. High dilution velocity is also a concern: the remaining 40,000m of drilling will require further equity financing, and the current 91M fully diluted shares will grow. The management team, while credible, has below-average direct insider ownership at approximately 3.9%.

The single most important catalyst to monitor is the maiden NI 43-101 resource estimate, expected approximately H2 2026 or early 2027 after the 75,000m program is substantially complete. A multi-million-ounce Indicated resource at grades above 1.5 g/t Au in the Argus corridor would materially re-rate this stock — and Gold Fields' presence suggests someone with deep technical capabilities believes that outcome is plausible. WATCH at C$1.70; revisit as a BUY candidate only after a resource estimate is in hand.
