Pan American Silver: Early Warning News Release

VANCOUVER, British Columbia--(BUSINESS WIRE)--Pan American Silver Corp. (NYSE: PAAS) (TSX: PAAS) (“Pan American” or the “Company”) has acquired ownership of 18,750,000 units of securities (each, a “Unit”) of Galleon Gold Corp. (TSXV: GGO) (“Galleon”), for C$0.60 per Unit, pursuant to a non-brokered private placement (the “Acquisition”), which was completed in connection with a brokered private placement by Galleon, all for an aggregate of 50,000,000 Units, with each Unit comprised of one common share of Galleon (each, a “Common Share”) and one-half of one Common Share purchase warrant (each whole warrant, a “Warrant”). Each Warrant entitles the holder thereof to acquire one additional Common Share at an exercise price of C$0.75 per Common Share until December 4, 2027.

Prior to the Acquisition, Pan American owned, directly or indirectly, or exercised control or direction over, no Common Shares, but had the right to acquire 17,777,777 Common Shares pursuant to the Debenture (as defined below), which represented approximately 18.66% of the total number of issued and outstanding Common Shares on a partially diluted basis.

Immediately following the Acquisition, Pan American now owns, directly or indirectly, or exercises control or direction over, 18,750,000 Common Shares, 9,375,000 Warrants and the Debenture which represent approximately 14.7% of the total number of issued and outstanding Common Shares on a non-diluted basis and approximately 29.7% of the total number of issued and outstanding Common Shares on a partially diluted basis. Pan American has agreed not to convert its Debenture or exercise its Warrants to the extent that Pan American would own (together with any person acting jointly or in concert with Pan American), directly or indirectly, more than 19.9% of the issued and outstanding Common Shares immediately following such exercise until the disinterested shareholders of Galleon have approved Pan American as a control person.

Galleon had previously issued an unsecured convertible debenture to Pan American for C$8,000,000 on August 13, 2025 (the “Debenture”). The Debenture has a term of 36 months from the date of issuance, bears interest at a rate of 10.0% per annum, payable in cash or Common Shares at the option of Pan American, and is convertible into Common Shares at a price of C$0.45 per Common Share. If the principal amount of the Debenture is converted into Common Shares, it would result in the issuance of up to 17,777,777 Common Shares, subject to the terms and conditions of the Debenture. If Pan American converted the principal amount of the Debenture and exercised its Warrants, Pan American would own 45,902,777 Common Shares, representing approximately 19.6% and 29.7% of the Common Shares on a fully and partially diluted basis, respectively.

The Acquisition was made for investment purposes. Pan American has a long-term view of the investment and may acquire additional securities of Galleon, including on the open market or through private acquisitions, or sell the securities, including on the open market or through private dispositions, in the future depending on market conditions, reformulation of plans and/or other relevant factors.

The foregoing disclosure regarding Pan American’s holdings is being disseminated pursuant to National Instrument 62-103 – The Early Warning System and Related Take-Over Bid and Insider Reporting Issues. A copy of an early warning report will be filed on Galleon's SEDAR+ profile at www.sedarplus.ca and may be obtained by contacting Ms. Siren Fisekci, VP, Investor Relations & Corporate Communications for Pan American, at 604-806-3191.
