Arctic Fox Lithium Corp. Transitions to NiobiumX Mining Inc. with New CSE Ticker NIOX Effective July 17, 2026

Rebranding from Arctic Fox Lithium to NiobiumX Mining: Strategic Intent

As announced on July 14, 2026, Arctic Fox Lithium Corp. is adopting the name NiobiumX Mining Inc. to better align with its diversified mineral property portfolio. This name change signals a strategic shift away from a sole lithium focus, although the company did not disclose specific new mineral assets, acquisitions, or exploration targets in the release.

The move to emphasize niobium reflects the growing importance of this critical mineral in Canada and globally. Niobium is widely used in high-strength steel alloys, superalloys, and emerging battery technologies. However, the announcement did not provide details on any niobium assets or resource estimates, so investors should not assume material niobium holdings based solely on the rebranding.

New CSE Trading Symbol NIOX to Commence July 17, 2026

NiobiumX Mining Inc. will begin trading on the Canadian Securities Exchange under the new ticker symbol NIOX at market open on July 17, 2026. The company confirmed no changes to share structure, share count, or trading terms accompany this rebrand. Shareholders will not need to exchange share certificates due to this administrative change, although the announcement did not specify certificate replacement procedures.

Currently listed on the CSE, Frankfurt Stock Exchange (FSE: O5K), and OTCQB (AFXLF), the company only confirmed the CSE ticker change to NIOX. Updates to FSE or OTCQB ticker symbols were not disclosed, and investors trading on those platforms should verify symbol changes with their brokers.

Assignment of New CUSIP and ISIN Identifiers

Following the corporate name change, new security identifiers have been issued: CUSIP number 653946103 and ISIN CA6539461039. These identifiers facilitate accurate recognition of the company’s common shares by financial institutions and trading systems.

Shareholders and institutional investors holding shares through brokerage or custodial accounts should expect their holdings to reflect the new CUSIP and ISIN post-transition. Although most brokerage systems update these automatically, investors are advised to confirm with their financial institutions, especially if they use these identifiers for record-keeping or settlement.

Company Overview: Junior Mineral Exploration in Transition

Arctic Fox Lithium Corp., headquartered in Vancouver, British Columbia, has historically focused on acquiring and developing mineral properties as a junior exploration company. The rebranding to NiobiumX Mining Inc. marks a significant repositioning of the company’s public identity. Such rebrands are common among junior explorers when strategic focus shifts, whether through new acquisitions, commodity targets, or portfolio realignment.

The announcement did not provide updated information on current property holdings, exploration status, or management beyond naming the Director, President, and CEO. No financial data, exploration results, or corporate presentations accompanied the release.

Clarifications on What the Name Change Signifies

The July 14, 2026 announcement confirms a corporate name change, a new CSE ticker symbol, and updated security identifiers effective July 17, 2026. It does not confirm any financing, property acquisition, resource estimate, joint venture, or operational development. The company described the name change as reflecting a broadened mineral portfolio but did not provide supporting details.

Forward-looking statements include standard disclaimers noting actual outcomes may differ materially. Investors should avoid drawing conclusions about the company’s asset base, financial condition, or commercial prospects solely from the name change.

Impact on Shareholders Holding AFX Shares

For existing shareholders, the transition to NiobiumX Mining Inc. is an administrative change that does not affect ownership rights or share proportions. No shareholder vote or approval related to the name change was mentioned, though such actions are typically governed by corporate bylaws and applicable law.

Investors with watch lists or alerts based on the AFX ticker should update them to reflect NIOX on the CSE starting July 17, 2026. Retail investors using Canadian brokerages may experience a brief symbol transition and should confirm the updated symbol before trading on or after the effective date. The announcement did not provide information on immediate share price impact.

Niobium’s Role as a Critical Mineral: Industry Perspective

The new corporate name highlights niobium, a transition metal gaining prominence in the critical minerals sector. Niobium is primarily used in high-strength, low-alloy steel and aerospace superalloys. Interest is also growing in niobium compounds for battery and energy storage applications, though commercial uses remain emerging.

Canada is recognized as a jurisdiction with niobium potential, with federal and provincial governments listing niobium as a critical mineral. However, this industry context does not imply NiobiumX Mining Inc. holds significant niobium resources or has favorable geology. No technical data, property descriptions, or qualified person reports were included in the announcement.

Multi-Exchange Listings Post-Rebrand

Arctic Fox Lithium Corp. maintains listings on the Canadian Securities Exchange, Frankfurt Stock Exchange, and OTCQB Venture Market in the U.S., providing access to a broad investor base across North America and Europe. The CSE listing under the new NIOX symbol will be effective July 17, 2026.

The announcement did not clarify if the FSE symbol O5K or OTCQB symbol AFXLF will change. Investors tracking the company across exchanges should consult official filings on SEDAR+ at www.sedarplus.ca or contact their brokers to verify current listing statuses and ticker symbols.

Regulatory Compliance and Exchange Confirmation

The release includes the standard Canadian Securities Exchange disclaimer that neither the CSE nor its Regulation Services Provider accepts responsibility for the press release’s adequacy or accuracy. This routine disclosure does not indicate any regulatory concerns regarding the name change.

Corporate name changes on the CSE require exchange approval and compliance with relevant Business Corporations Act provisions. The company’s indication that the change will proceed on July 17, 2026 suggests all necessary administrative and regulatory approvals have been secured. No pending conditions or approvals were noted in the announcement.
