TRINITY ONE METALS PROVIDES PROJECT AND CORPORATE UPDATE

Trinity One Metals Ltd. has provided an update on the Silver-1 mine in Ecuador and a corporate update.

Following the company's June 10, 2026, operations update, Trinity One has continued to advance Silver-1 through local field preparation, community engagement, environmental baseline work and planning for the next stage of technical programs.

The company has established a local project office in San Bartolome. The office will support community engagement, field logistics, technical co-ordination, sample handling and planning for coming work programs at Silver-1.

The company is continuing preparations for the planned tailings sampling program, which is currently expected to commence in August, 2026. Trinity One is in the process of selecting a contractor to complete the program, which will be designed to support a more detailed evaluation of the historic tailings material at Silver-1.

In addition, the company has selected a contractor to complete the planned drone magnetic survey at Silver-1, with mobilization expected within the next fortnight. The survey will play an important role in refining the company's understanding of the project's structural setting and supporting the generation of high-priority targets for diamond core drilling.

Thomas Wood, chief executive officer of Trinity One, commented: "The establishment of a local office and upcoming mobilization for the drone magnetic survey are important steps in moving the project toward systematic evaluation and future drill targeting. The magnetic survey is expected to be a key input in identifying targets for diamond core drilling."

Corporate update

The company also announces that its common shares, previously trading on the OTC Basic Market under the ticker symbol ARJNF, are to commence trading on the OTC Basic Market under the ticker symbol TOMXF, effective July 9, 2026. The ticker symbol was changed to better align with the company's TSX Venture Exchange ticker symbol. No action is required by shareholders with respect to the ticker symbol change.

The company further announces that it has adopted a new equity incentive plan, which was approved by shareholders at the annual general and special meeting of shareholders held on June 18, 2026.

The new compensation plan supersedes the company's previous 10-per-cent rolling stock option plan and provides the company with the ability to issue stock options, restricted share units, performance share units and deferred share units to directors, officers, employees and consultants of the company or its subsidiaries.

The aggregate number of common shares reserved for issuance in respect of stock options will not exceed 10 per cent of the company's then total issued and outstanding common shares, calculated as at the date of any grant. The aggregate number of common shares reserved for issuance in respect of restricted share units, performance share units and deferred share units granted under the compensation plan will not, in the aggregate, exceed 6,723,487 common shares, representing 10 per cent of the total number of issued and outstanding common shares, calculated on a non-diluted basis as at the date of implementation of the compensation plan.

The compensation plan is subject to final approval by the TSX Venture Exchange. Further details regarding the compensation plan are included in the company's management information circular filed on SEDAR+ in connection with the annual general and special meeting.
