SHINE PROVIDES UPDATE ON ACQUISITION OF RED CLOUD SILVER

Shine Minerals Corp. has provided an update to its press release dated Dec. 11, 2025, whereby it announced that it has entered into a binding letter of intent dated Dec. 10, 2025, with Red Cloud Silver Ltd. (RCS) outlining the principal terms of a 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 per cent of RCS and its option on the Silver District project, which has a recorded production including 1.56 million ounces (44,225 kilograms) silver and 2.33 million lb (1.06 million kg) lead, mostly produced during a peak production period from 1883 to 1893. With this acquisition, the company gains exposure to a large, multitarget system with demonstrated silver, fluorspar and barite mineralization across a district-scale land package. Each of which are United States critical minerals.

Dev Randhawa, chief executive officer 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-per-cent 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 Dec. 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 Policy 5.2, and is instead expected to be treated as a fundamental acquisition in accordance with TSX-V Policy 5.3. The company will provide further disclosure as required under TSX-V 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 metres," comments Devinder Randhawa, chief executive officer 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-kilometre area and include the West (4.5 kilometres 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 metres to 45 metres in width and have been tested to an average depth of only 35 metres (468 historical drill holes). 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 metres) 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.
