[{"type":"text","content":" Vancouver, British Columbia--(Newsfile Corp. - May 14, 2026) - Tiernan Gold Corp. (TSXV: TNGD) (\"Tiernan\" or the \"Company\") announces the initiation of a comprehensive suite of technical and environmental studies in advancement of a Pre-Feasibility Study (\"PFS\") for its Volcan Gold Project (the \"Project\" or \"Volcan\"), located in the Maricunga Gold Belt, Chile. These initiatives build directly on the results of the recently completed core relogging program, which confirmed that gold mineralization at Volcan is primarily controlled by veining and alteration intensity and significantly strengthened the foundational geological framework for the Project's 9.8 million ounce Measured and Indicated gold resource. Strategically focused on the optimization of the Volcan Project, the Company has engaged purpose-selected technical consultants and initiated multiple parallel workstreams in the following areas; each critical to advancing Volcan through engineering and a filed Environmental Impact Assessment (\"EIA\"). Geology Mining Metallurgy Environmental Baseline Permitting Highlights for studies underway include: Ausenco retained as lead PFS consultant, overseeing process engineering, environmental baseline, and NI 43-101 Technical Report compilation Deswik engaged for open pit mine design and optimization, including trade-off analysis SLR retained to prepare an updated, geologically constrained Mineral Resource Estimate (\"MRE\") incorporating the recent relogging results SGS commissioned for a comprehensive metallurgical testwork program, expanded to 36 variability samples, covering full characterization, HPGR evaluation, and locked-cycle CIC/SART testing Gestión Ambiental Consultores (\"GAC\") retained for EIA consulting and environmental strategic support, bringing 35+ years of SEIA experience including major Atacama Region mining projects Three meteorological, air quality and dust monitoring stations successfully installed at site in February 2026, following CONAF research permit approval - a key milestone for the environmental permitting baseline \"These workstreams are a deliberate, coordinated de-risking sequence. The updated geologically constrained resource estimate, the metallurgical testwork program, the mine design & trade-off studies, and the installation of our environmental monitoring stations are each purpo...
