Oroco Congratulates Hudbay Minerals Inc.

VANCOUVER, Canada, Aug. 14, 2025 (GLOBE NEWSWIRE) -- Vancouver, CANADA. 鈥� August 14^th, 2025 鈥� Oroco Resource Corp. (TSX-V: OCO; OTCQB: ORRCF) (鈥�Oroco鈥� or 鈥渢he Company鈥�) extends its congratulations to Hudbay Minerals Inc. (鈥�Hudbay鈥�)聽for its agreement with Mitsubishi Corporation (鈥�Mitsubishi鈥�) announced on聽August 13^th 2025, whereby Mitsubishi will acquire a 30% interest in Hudbay鈥檚 Copper World project in Arizona for consideration of US$600 million, structured as US$420 million at closing for a 30% equity interest, and $180 million as a matching contribution within 18 months of closing.

Hudbay鈥檚 transaction with Mitsubishi underscores the strategic importance and market appetite for large, high-quality North American copper projects supported by robust technical studies. Mitsubishi's acquisition of an interest in the Copper World project, which benefits from a September 8, 2023 Pre-Feasibility Study (鈥�PFS鈥�), demonstrates the value of advancing open-pit copper deposits through this critical stage of technical and economic definition.聽

鈥淲e congratulate Hudbay and Mitsubishi on this significant transaction,鈥� said Craig Dalziel, Chairman of Oroco Resource Corp. 鈥淭he resulting US$1.4 billion project valuation and the calibre of the partnership are validation that聽high-quality copper projects with strong technical underpinnings and聽a well-executed PFS can聽attract world-class purchasers and development partners. 聽This further supports Oroco's decision to advance Santo Tom谩s to the Pre-Feasibility Study stage.聽 Santo Tom谩s shares many important characteristics with Copper World: a large-tonnage, open-pit copper porphyry deposit close to infrastructure, with the potential to be a long-life, low-cost producer.聽 For this reason, we invite interested readers to compare the Copper World and Santo Tomas project metrics as found on their respective corporate websites.鈥澛�

Oroco is advancing the Santo Tom谩s copper project toward completion of its own PFS, building on the drilling and metallurgical programs that have resulted in the publication of an August 20, 2024 Preliminary Economic Assessment study.聽 The Company believes that a well-supported PFS will position Santo Tom谩s as a premier development opportunity in the global copper sector at a time of strong demand for critical minerals.

ABOUT OROCO

The Company holds a net 85.5% interest in those central concessions that comprise 1,173 hectares 鈥渢he Core Concessions鈥� of The Santo Tomas Project, located in northwestern Mexico. The Company also holds an 80% interest in an additional 4,948 hectares of mineral concessions surrounding and adjacent to the Core Concessions (for a total Project area of 6,121 hectares, or 15,125 acres).聽 The Project is situated within the Santo Tomas District, which extends up to the Jinchuan Group鈥檚 Bahuerachi Project, approximately 14 km to the northeast. The Project hosts significant copper porphyry mineralization initially defined by prior exploration spanning the period from 1968 to 1994. 聽During that time, the Project area was tested by over 100 diamond and reverse circulation drill holes, totaling approximately 30,000 meters. 聽Commencing in 2021, Oroco conducted a drill program (Phase 1) at Santo Tomas, with a resulting total of 48,481 meters drilled in 76 diamond drill holes.

Subsequent to the drilling at Santo Tomas, the resource estimates and engineering studies led to a revised MRE and an updated PEA being published and filed in August of 2024, which studies are available online at the Company鈥檚 website at www.orocoresourcecorp.com and by reviewing the Company profile on SEDAR+ at .

The Santo Tom谩s Project is located within 170 km of the Pacific deep-water port at Topolobampo and is serviced via highway and proximal rail (and parallel corridors of trunk grid power lines and natural gas) through the city of Los Mochis to the northern city of Choix. The property is reached, in part, by a 32 km access road originally built to service Goldcorp鈥檚 El Sauzal Mine in Chihuahua State.
