ATLANTA, Nov. 28, 2025 – Encampment Minerals, Inc. (referred to as the “Acquiror“) announced that on November 21, 2025 (the “Acquisition Date“), it purchased 22,222,222 units of Green Bridge Metals Corporation (“Green Bridge“) at a price of $0.09 per unit, totaling $2,000,000. This acquisition relates to an Option and Earn-In Agreement from July 11, 2025, where Green Bridge was granted an option by Encampment Minerals to earn up to a 70% stake in Encampment’s Serpentine Project, located about 5 km southeast of Babbitt, St. Louise County, Minnesota. Each unit consists of one common share of Green Bridge (a “Common Share“) and half of a Common Share purchase warrant (each full warrant, a “Warrant“). Each whole Warrant can be exercised to buy one Common Share (a “Warrant Share“) for $0.15 until November 21, 2028. These newly issued securities are subject to a legal hold period of four months and one day from their issuance date, as per securities laws, and are also part of a voluntary escrow arrangement: 25% will be released after the statutory hold period expires, and another 25% will be released on the 6-month, 12-month, and 18-month anniversaries of the Acquisition Date.

Before the Acquisition Date, the Acquiror owned no Common Shares. Following the issuance of Common Shares on November 21, 2025, the Acquiror now holds a total of 22,222,222 Units, which include 22,222,222 Common Shares and 11,111,111 Warrants. As of the Issuance Date, and assuming Green Bridge has not issued more Common Shares since then, the Acquiror possesses 22,222,222 Common Shares, accounting for about 11.29% of Green Bridge’s currently issued and outstanding Common Shares, along with Warrants that can be converted into 11,111,111 Warrant Shares. If all Warrants were exercised, the Acquiror’s ownership of issued and outstanding Common Shares would be approximately 16.04% on a partially diluted basis.

The Acquiror purchased these Common Shares as an investment. Going forward, the Acquiror may, at various times, directly or indirectly buy more Green Bridge securities (which includes, but is not limited to, exercising the Warrants for Warrant Shares as per their terms) or sell these securities. Such decisions will depend on several factors, including overall market and economic conditions, and other available investment and business opportunities.

Green Bridge Metals Corporation’s head office is located at 800- 1199 West Hastings Street, Vancouver, BC, V6E 3T5. The Acquiror’s address is Two Midtown Plaza, Suite 1990 1349 West Peachtree Street, Atlanta, Georgia, 30309. The early warning report filed by the Acquiror is available on Green Bridge’s SEDAR+ profile.
