OREX MINERALS HIGHLIGHTS SILVER VIPER'S HIGH-GRADE DRILL RESULTS AT LA VIRGINIA, SONORA, MEXICO

Orex Minerals Inc. has shared the drill results released by Silver Viper Minerals Corp. from its continuing drill program at the La Virginia gold-silver project in Sonora, Mexico. These results are being shared in the context of Orex's previously announced sale of its interest in the Coneto silver-gold project to Silver Viper (March 16, 2026), a transaction that remains subject to the receipt of TSX Venture Exchange approval.

Upon closing of that transaction, Orex will receive 9,908,438 common shares of Silver Viper, representing its pro rata portion of the all-share consideration valued at $15-million (U.S.). This equity position will provide Orex shareholders with continuing, meaningful exposure to Silver Viper's portfolio of district-scale precious metals assets across Mexico -- including La Virginia and the Coneto project that is the subject of the pending transaction.

The reported drill results from Silver Viper serve to underscore the significant value underpinning Orex's negotiated equity stake and reinforce management's confidence in the strategic rationale of the Coneto transaction.

Silver Viper's La Virginia gold-silver project is a resource-stage epithermal gold-silver system in Sonora, Mexico. The project hosts a current mineral resource estimate of 154,000 indicated ounces of gold at 0.78 gram per tonne and 6.92 million ounces of indicated silver at 35 grams per tonne plus 260,000 inferred ounces of gold at 0.8 gram per tonne and 12.94 million inferred ounces of silver at 40 grams per tonne, based on the 2021 resource estimate. An updated resource estimate is anticipated in Q2 2026, incorporating the current infill and expansion drilling program. The continuing program, originally scoped at 5,000 metres, has been expanded to facilitate further infill drilling at El Rubi with the goal of converting inferred mineral resources to the indicated category.

Silver Viper reports that the announced results cover a total of 5,646.4 metres of drilling across 18 drill holes (seven exploration holes and 11 infill holes), with drilling continuing at the site at the time of release.

"These exceptional results from Silver Viper's La Virginia drill program are highly encouraging for Orex shareholders. We structured the Coneto transaction as an all-share deal precisely because we believe in the quality of Silver Viper's assets and the strength of their exploration platform. Today's results -- particularly the headline interval of 11.70 m at 9.18 g/t gold and 352.0 g/t silver in hole LV26-345 -- speak for themselves. They validate our conviction that Orex's equity position in Silver Viper represents meaningful, ongoing upside for our investors as we await TSX-V approval to close the Coneto transaction. We look forward to continuing to update our shareholders as this exciting program advances," stated John Eren, president and chief executive officer Orex Minerals.
