Dear Sir,

Re: Extension of Exclusivity Period

Reference is made to the binding letter of intent dated August 5, 2025 (the “LOI”) between 1390120 B.C. Ltd. (“Numberco”) and Getty Copper Inc. (“Getty”). Capitalized terms used but not defined herein have the meanings given to them in the LOI.

This letter will serve to confirm the agreement of Numberco and Getty to amend the LOI by deleting the reference to “the end of the Due Diligence Period” in the first paragraph of Section 3 of the LOI and replacing that reference with “October 31, 2025”, the effect of such amendment being to extend the duration of the Exclusivity Period until the earlier of (i) October 31, 2025; (ii) the date of the execution of a mutually acceptable Agreement; and (iii) the termination of the LOI in accordance with its terms.

The foregoing amendment will take effect as of the date hereof. Numberco and Getty confirm that the LOI, amended as detailed above, remains and continues in full force and effect. The LOI and this letter shall together constitute and be read as one and the same written instrument. This letter may be executed in counterparts, each of which will be deemed to be an original and all of which taken together will be deemed to constitute one and the same instrument. Delivery of an executed signature page to this letter by any party by electronic transmission will be as effective as delivery of a manually executed copy of this letter by such party.

Yours truly,

1390120 B.C. LTD.
