Bulgold confirms major epithermal gold system at Kopernica, Lutila

TORONTO, ON / ACCESS Newswire / September 29, 2026 / BULGOLD Inc. (TSXV:ZLTO) (the "Company" or "BULGOLD") is pleased to announce the geological and geochemical modeling results from its 2026 diamond drilling programme at the Kopernica Vein System, located within the Lutila Gold Project, Slovak Republic.

The 2026 campaign - comprising drill holes KPDD002, KPDD003, KPDD004 and KPDD005 - has successfully achieved a critical technical milestone, confirming the discovery of a major epithermal upflow zone hosted within a rhyolite rock flow dome package located immediately south of the historic Kremnica low-sulfidation epithermal gold mine.

Intact Epithermal System Confirmed: Low-cost, shallow drilling successfully verified a robust, fully intact low-sulfidation epithermal system across the Company's 100%-controlled area.

Broad Upflow Zone Defined: Integrating data from the 2026 campaign, two earlier BULGOLD holes, and three historic holes outlines an epithermal upflow zone at least 500 meters wide and up to 1,000m long. The zone features widespread low-grade gold, characteristic epithermal rock textures and supporting pathfinder elements, arsenic (As), antimony (Sb) and thallium (Tl).

Advanced Predictive Modeling: Combining comprehensive multi-element geochemistry with targeted X-ray diffraction (XRD) data has successfully mapped the 3D structural architecture of the host rhyolite block. This new alteration and mineralisation model provides clear vectors toward quartz vein structures.

Key Mineralisation Trends Defined: Drill data has mapped specific high-priority zones and new potential across the rhyolite block: First Adularia Discovery (KPDD005): Identified the first adularia on the property within a 60-meter downhole intersection of intense-to-strong silicification on the current eastern margin of the upflow zone.

West Vein Potential (KPDD004): Pervasive quartz-illite alteration id
