Vancouver, December 17, 2025 - Shine Minerals Corp. (TSXV: SMR.H) ("Shine" or the "Company") is pleased to provide an update to its press release dated December 11, 2025 whereby it announced that it has entered into a binding letter of intent dated December 10, 2025 with Red Cloud Silver Ltd. ("RCS") outlining the principal terms of a proposed transaction (the "Proposed Transaction").

The Proposed Transaction positions Shine to secure a high-quality exploration opportunity in one of the most historically productive and infrastructure-rich silver districts in the American Southwest. By obtaining the right to acquire 100% of RCS and its option on the Silver District Project (the "Project"), which has a recorded production including 1.56 Moz (44,225 kg) silver and 2.33 million lbs (1.06 million kg) lead, mostly produced during a peak production period from 1883-1893¹. With this acquisition, The Company gains exposure to a large, multi-target system with demonstrated silver, fluorspar and barite mineralization across a district-scale land package. Each of which are US Critical Minerals.

Dev Randhawa, CEO of Shine stated: "The Silver District Project represents a rare opportunity to consolidate a historically productive silver-dominant district in one of the most mining-friendly jurisdictions in the United States. Located in Arizona's La Paz County, the Project hosts a broad system of high-grade silver, fluorspar and barite showings across a large, underexplored land position with demonstrated potential for scale. We believe the property offers exceptional discovery upside, supported by modern exploration, strong geology, and a clear pathway to 100% ownership. This is exactly the kind of high-impact asset that can reposition Shine and drive meaningful value creation for our shareholders."

The Company would like to clarify that further to its previous press release dated December 11, 2025 whereby it announced the Proposed Transaction, the Proposed Transaction is not expected to constitute a reverse takeover or change of business under TSX Venture Exchange ("TSXV") Policy 5.2, and is instead expected to be treated as a fundamental acquisition in accordance with TSXV Policy 5.3. The Company will provide further disclosure as required under TSXV Policy 5.3 as additional details become available or upon execution of a definitive agreement.

"The Silver District project includes 468, tightly spaced drill holes defining 10 key zones of high-grade silver oxide (and fluorspar-barite) mineralization starting from surface and extending to an average depth of only 30 meters," comments Devinder Randhawa, CEO of Shine Minerals. "The Silver District project has excellent potential for expansion down-dip, along-strike and down-plunge of established mineralized zones."

At Silver District, silver enriched calcite-barite-fluorite carbonate veins at Silver District cover a 3.5 by 6.5-kilometer area and include the West (4.5 kilometers strike-length), Central (3.5 km strike-length) and East (4.5 km strike-length) vein-fault zones. Mineralized veins are exposed at surface, range from 7.5 meters to 45 meters in width and have been tested to an average depth of only 35 meters (468 historical drill holes)^1,2. Shine Minerals considers the Silver District Project to be highly prospective for additional silver-fluorspar-barite veins adjacent (along-strike) and below (down-dip, down-plunge) previously identified mineralization. Due to the extremely shallow depths of historical drilling, Shine Minerals believes there is excellent potential at depth where dominantly oxide mineralization (exposed at surface) is expected to transition to dominantly sulphide mineralization.

The Silver District Project contains 468 historical drill holes (average depth 30 meters) that demonstrate near-surface silver-fluorspar continuity across the three main trends. The Silver District Project was discovered in 1862, with most of the historical production coming from the underground Red Cloud and Clip mines. There have been occasional small- scale development activities since, and the area remains a source of specimen wulfenite, an oxide lead molybdate mineral, and vanadinite, an oxide lead vanadium mineral.
