Provides ability to bolster balance sheet for growth and enable repayment of existing gold prepayment facility

Toronto, Ontario – March 31, 2026 – Minera Alamos Inc. (“Minera Alamos” or the “Company”) (TSXV: MAI; OTCQX: MAIFF) is pleased to announce that on March 25, 2026 the Company executed a term sheet for a new US$75 million revolving credit facility (the “Revolver”) with The Bank of Nova Scotia (“Scotiabank”) and National Bank of Canada (“National Bank”). The term sheet has been approved by both banks’ credit committees with closing and initial funding of the Revolver subject to negotiation and execution of definitive loan, guarantee and security agreements and satisfaction of certain customary closing conditions.

Revolving Credit Facility Key Terms

• Capacity of US$75 million available on closing
• Term of three years from closing date
• Interest rate of Term SOFR plus a margin spread between 3.25% and 4.25% based on the Company’s Total Net Debt / EBITDA ratio
• Revolver to have senior security over the Company’s material assets
• Customary financial covenants including: (1) Total Net Debt / EBITDA ≤ 3.0x, (2) Interest Coverage ≥ 3.0x, and (3) minimum of liquidity of US$10 million
• Scotiabank will be Administrative Agent, with both Scotiabank and National Bank acting as Co-Lead Arrangers and Joint Bookrunners

Darren Blasutti, EVP Corporate Development, commented, “We are immensely proud to partner with two tier-1 Canadian banks and global mining finance leaders. This US$75 million Revolver will provide us with lower cost debt financing, and combined with our strong working capital position, will allow us to advance our high-quality pipeline of permitted U.S. growth projects without equity dilution. Following closing, the initial drawdown under the Revolver will enable the repayment of the existing gold prepayment facility which will give our investors more meaningful participation to current high gold prices. We appreciate the collaboration with National Bank and Scotiabank and look forward to their continued support as we aim to become a leading, U.S. focused intermediate gold producer by growing production and developing our pipeline of high-quality, low-capital projects.”

Repayment of Auramet Gold Prepayment Facility

The Company intends to use an initial drawdown under the Revolver to extinguish its gold prepayment facility (the “Gold Prepay”) with Auramet International, Inc. (“Auramet”), who has helped support the Company’s financing efforts in prior lower gold price environments. The Gold Prepay, originally entered into on October 1, 2025, as a part of the Company’s acquisition of Nevada assets from Equinox Gold Corp., provided upfront cash of US$25 million in consideration for delivery of 7,830 gold ounces in 18 equal monthly installments of 435 gold ounces from April 2026 to September 2027. Repayment of the Gold Prepay will be done by delivering one cash equivalent payment of the owed gold ounces, priced at the prevailing spot gold price at the time of repayment. Repayment and termination of the Gold Prepay is subject to closing of the Revolver and initial funding. There is no assurance that the credit documents in respect of the Revolver will be completed or that any amount will be drawn under the Revolver.

Update on U.S. Growth Projects

As previously reported, the Company is in the final stages of delivering the results of a pre-feasibility study on its 100%-owned Copperstone Gold Project located in La Paz County, Arizona. The Company is also advancing the Pan life-of-mine plan optimization and is concurrently advancing mine development studies on the adjacent Gold Rock Project, located just 7 miles southeast from the Pan mine. There is potential to realize significant operating and cost synergies by combining the Pan mine and Gold Rock Project and the Company anticipates releasing an updated technical report in Q4 of 2026.
