[{"type":"text","content":" Vancouver, British Columbia--(Newsfile Corp. - November 12, 2025) - Questcorp Mining Inc. (CSE: QQQ) (OTCQB: QQCMF) (FSE: D910) (the \"Company\" or \"Questcorp\") is pleased to announce the completion of the first phase of drilling at the La Union gold and silver Project in Sonora, Mexico. A total of 12 diamond core holes were completed for a total of just over 1,600 metres across six priority targets. The work is being advanced with funding through partner Questcorp Mining Inc. (\"Questcorp\") under the option agreement announced earlier in 2025 with Riverside as Operator and managing the exploration program. Program Highlights 12 core holes completed totaling >1,600 m. Six targets drilled: Union Mine, Union Norte, Cobre, Luis, Famosa, and Famosa Mag. Three past-producing mine areas tested adjacent to historic workings to evaluate continuity. >700 half-core samples shipped; assays pending. Holes oriented as angle and near-vertical to cut stratigraphy and structures typical of Carbonate Replacement Deposit-type (\"CRD\") systems, with focus beneath oxidized horizons generally <150 m depth. \"This first exploration phase accomplished initial drill holes into 6 target areas. We tested multiple shallow gold and base metals targets, confirmed the key carbonate host units recognized by historic mining at Union and Famosa, and gathered the structural and alteration data to further progress efficient mineral exploration,\" said Dr. John-Mark Staude, President and CEO of Riverside Resources. \"This historically mined CRD district, validated by new drilling and improved datasets, advances our geologic model and supports the potential for a large-scale discovery. With six targets advanced and more than 700 samples at the lab, once results are received, we will scope the next exploration program and focus on the most prospective trends indicated by assay results, stratigraphy, structure, and geophysics.\" Questcorp President & CEO said, \"We are excited to have completed this first phase of drilling at La Union through the guidance of the accomplished Riverside technical team and their subcontracted drillers. The company anxiously awaits the return of the assays from the lab as we look to plan follow on development.\" Drilling Update by Area Union Mine: Three holes at the Union Mine targeted manto horizons and chimney/feeder ...
