Technical & forward-looking disclosure.

1. Exploration-stage project

The Nicholson Property is presented as an exploration-stage gold project. Our historical project documentation does not establish a compliant mineral resource, mineral reserve, feasibility study, economic assessment, producing mine or production forecast. Mineral occurrence and selected high-grade samples do not establish commercial viability.

2. Historical grades and technical records

Historical assays include reported results of 658.48 g/t Au in a grab sample (1998), 298.43 g/t Au over 0.5 metres in a drill intersection (2009), and 241.03 g/t Au from the November 2024 sampling program as stated in the Phase I proposal. These values are historical and have not been independently verified for this website. Complete original assay certificates, QA/QC logs, surveys and source technical validation have not been supplied. Grab samples are selective and are not necessarily representative of overall grade or mineralization.

3. Drill intercepts and geological continuity

Reported downhole lengths are not necessarily true widths. The historical 280-metre Main Showing exposure, approximately 500-metre Dog River offset and interpreted total trend of at least 780 metres are descriptions in the supplied proposal, not proof of continuous mineralization, tonnage or grade. Geological models and interpretations remain subject to testing.

4. Proposed Phase I and Phase II work

Phase I comprises three proposed holes totalling 160 metres. Phase II comprises 13 proposed holes totalling 900 metres, collectively 16 holes and 1,060 metres. The 2025 schedules are proposed programs. They do not confirm drilling completion, permits, financing, contractor mobilization or new assay results. A phase-sequencing reference in the Phase II source is inconsistent; we present the two schedules separately pending technical confirmation of a final sequence.

5. Phase II budget discrepancy

The Phase II proposal states direct costs of $196,880, a “15% contingency” of $33,220 and a grand total of $230,000. A 15% contingency on $196,880 is $29,532 and the corresponding total is $226,412. The original stated amounts are not arithmetically consistent. The proposal does not explicitly identify the dollar currency. Costs are historic estimates and not a current or approved capital budget.

6. Historical maps and land tenure

Historical maps may feature legacy project names, surrounding mine properties and historical Ontario MLAS layers. The historical highlights map bears the designation “FMEL Missanabie Project”, which requires reconciliation against FMML Nicholson tenure records. The adjacent-mines map uses a May 2015 regional base and identifies nearby operations that are not Company assets. Maps cannot establish current claims, title, property boundaries, permitting or land-access rights. Verify against current public records and underlying legal documents.

7. Qualified Person and regulatory disclosure

We do not claim that a Qualified Person has reviewed or approved the technical statements for this publication under National Instrument 43-101. Any disclosure governed by securities laws must be reviewed and approved through the appropriate qualified technical and legal process before use.

8. Forward-looking statements

Statements concerning mineral potential, future drill programs, exploration targets, project advancement, financing, partnerships, permitting, resource estimation and economic outcomes are forward-looking. Material differences may arise due to geology, grades, sampling uncertainty, regulatory requirements, Indigenous rights and consultation obligations, funding, operations, market conditions, costs and other factors. There is no assurance that planned programs will occur or produce positive outcomes.

9. Editorial photography and document reproductions

Stock photos depict illustrative mining and landscape scenes outside the project unless explicitly stated otherwise. Maps and project sections reproduce supplied historical records for context and may contain third-party marks and unverified legacy annotations. These images are not evidence of current Company ownership or field activity.

10. Investor decision-making

This website contains no securities offer, guarantee, public-market status assertion, valuation conclusion, liquidity representation or return forecast. Visitors should seek independent professional advice and rely on authorized technical, legal and financial disclosure before making investment decisions.
