PRECORE GOLD WELCOMES TENURED GEOLOGIST RAUL CARBAJAL AS SENIOR PROJECT MANAGER AT ITS ARIKEPAY PROJECT IN PERU

Precore Gold Corp. has welcomed Raul Carbajal as senior project manager of the company's highly prospective brownfield copper-gold flagship, the Arikepay project in southern Peru.

Paul A. Dumas, executive chairman of Precore Gold, stated: "We are happy to have Raul join our team in Peru. His knowledge and experience around geology -- especially porphyry systems like at our Arikepay project -- as well as large-scale project management and development will be invaluable as we get into exploration and development work at Arikepay."

Mr. Carbajal is a senior geologist with more than 25 years of experience leading mining exploration and development projects in South America. His expertise spans gold, copper and other metals, including heavy mineral deposits. His past tenure includes overseeing large-scale drilling campaigns and delivering both the JORC (Joint Ore Reserves Committee) reporting (Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves) and the National Instrument 43-101 securities regulatory instrument in Canada for a number of projects on which he was lead.

Most recently as senior project manager, Mr. Carbajal led a successful 20,000-metre drill campaign at C3 Metals Inc.'s Jasperoide project, located in the prolific high-grade Andahuaylas-Yauri porphyry-skarn belt of southern Peru. His expertise and collaboration contributed to the identification of a number of skarn prospects and two porphyry prospects along the renowned belt within C3 Metals' concessions. He was also responsible for the data compilation that was the foundation of the project's July, 2023, NI 43-101 technical report mineral resource update.

Prior to that, Mr. Carbajal worked as operations supervisor at Minera Chinalco Peru at its Toromocho copper mine in the Morococha district of Peru, which is, today, one of the largest copper mines in the world, with significant reserves and production capacity. While at Chinalco, Mr. Carbajal was in charge of managing the drilling campaigns for the large-scale infill project, which led to an important increase in mineral reserves. Today, Toromocho produces approximately 250,000 tonnes of copper concentrate annually, accounting for approximately 10 per cent of Peru's copper output (Geomechanics, April, 2026).

From 2009 to 2015, Mr. Carbajal served as senior project manager and geologist at Latin Resources' (now Pilbara Minerals) heavy minerals Guadalupito project in northern Peru and was responsible for delivering the JORC-defined inferred resource estimate of 1,073 million tonnes at 6.1 per cent heavy minerals at the project's Los Conchales deposit, successfully increasing Guadalupito's total JORC inferred resource by 371 per cent to 1,465 million tonnes at 5.7 per cent heavy minerals in situ (Latin Resources, February, 2013).

Prior to 2009, Mr. Carbajal worked for Rio Tinto, where he acted as project geologist, managing key copper and gold exploration projects, including advancing the geological understanding of the Mina Justa project (2024 proven and probable reserves 248.9 million tonnes copper) as well as managing and developing the Constancia project for its subsequent sale to Norsemont Mining (later acquired by Hudbay Minerals in 2011; 2025 proven and probable reserves of 488 million tonnes copper).
