METALLIS ANNOUNCES ADOPTION OF AMENDED & RESTATED 2024 SECURITY BASED COMPENSATION PLAN

VANCOUVER, BC, Dec. 3, 2025 /CNW/ - Metallis Resources Inc. (TSXV: MTS) (OTCQB: MTLFF) ("Metallis" or, the "Company") announces that, at its annual and special meeting of shareholders held on November 21, 2024, disinterested shareholders approved the Company's Amended and Restated 2024 Security-Based Compensation Plan (the "2024 Plan"). The 2024 Plan replaces and supersedes the Company's Amended and Restated 2023 Stock Option Plan (the "2023 Plan").

The 2024 Plan was presented to shareholders for their annual approval at the Company's most recent annual and special meeting held on November 13, 2025, where it received shareholder approval.

The 2023 Plan was a 10% rolling stock option plan that reserved for issuance up to 10% of Metallis' issued and outstanding common shares from time to time.

The newly adopted 2024 Plan introduces a broader, dual-component structure consisting of the following:

(a)	a rolling stock option component reserving for issuance up to 10% of        the Company's issued and outstanding common shares as at the date        of any stock option grant; and
(b)	a fixed restricted share unit ("RSU") component reserving 1,500,000       RSUs in aggregate.

Summary of Key Features of the 2024 Plan:

Stock Options:

Under the option component of the 2024 Plan, directors, officers, employees, consultants and eligible investor-relations personnel may receive stock options, all administered by the Board based on Compensation Committee recommendations. The option pool represents up to 10% of Metallis' issued and outstanding shares. Options may be granted for terms of up to 10 years at an exercise price not less than the market price at the time of grant, and are subject to vesting conditions set by the Board. Options are non-transferable, subject to standard termination provisions, and any insider and investor-relations grants remain within the customary sub-limits.

Restricted Share Units (RSUs):

The RSU component provides for a fixed pool of up to 1,500,000 RSUs, each subject to a minimum one-year vesting period. Once vested, RSUs may be settled in shares, cash, or a combination thereof, based on fair market value at the time of settlement.

RSU grants are subject to standard insider and consultant limits, termination provisions and non-transferability, and any unvested RSUs are generally forfeited on termination unless otherwise determined by the Company. The RSU component is subject to disinterested shareholder approval.
