Terra Balcanica Resources Corp. announced that it has completed the 2,000 m, Phase II drill program at the flagship, 216 km2 Viogor-Zanik project (the Project) in eastern Bosnia and Herzegovina. Drilling Brezani Target Completed: The 2023 diamond drilling at the Brezani target focussed on testing the coincident magnetic-conductivity anomaly at depth below the Au-skarn mineralization observed on surface.

Further shallow drillholes BRE23001-004 aimed to add scale to the initial 88 m at 0.61 g/t AuEq intercepted in drillhole BREDD002, all within a > 800 m NW/SE trending Au in soil anomaly. Drillhole BREDD002: Continued from a depth of 215 m to 674 m in 2023 commencing in the same chlorite-sericite altered diorite which returned 0.26 g/t Au (214 - 215 m) in 2022 drilling. At a depth of 482.1 m a 9.8 m continuous zone of banded vein and sulphide cemented breccias with characteristics of both low and intermediate sulphidation epithermal deposits was intersected.

The margins of the vein host repeating bands of chalcedonic quartz-rhodochrosite-calcite and sulphides/sulphosalts stibnite-pyrite-arsenopyrite-sphalerite-galena-jamesonite. The centre of the structure is dominated by hydrothermal breccia with a sulphide-quartz-carbonate cement. Clasts are banded vein fragments and wall rock hornfels.

In the vein footwall the lithology changed to 118.4 m of chlorite-sericite altered diorite porphyry intrusive. Sinuous quartz-pyrite-molybdenite veins, quartz-magnetite, anhydrite-carbonate, pyrite-chlorite, and pyrrhotite-carbonate veining is present alongside disseminated pyrite-pyrrhotite. Drillhole BRE23001: Located 102 m SW of the initial discovery hole at Brezani, which returned 0.61 g/t AuEq over 88 m from surface BRE23001 intercepted a similar package of calc-silicate mineralization with a strong chlorite retrograde overprint.

Intervals of coarse garnet-pyroxene skarn were also intercepted in contact with dioritic intrusives. Drillhole BRE23002: Located 91 m west of BREDD002 intersected a new style of mineralization for the Brezani target. Commencing at 98 m depth a sulphide-calcite cemented contact breccia between altered diorite and silicic hornfels was encountered.

The sulphide matrix was composed of pyrite-sphalerite-galena-pyrrhotite-chalcopyrite with individual sphalerite crystals up to 3 cm. The breccia was semi-continuous until 105.2m where it graded into patchy brecciation and intermediate sulphidation veining to 117.6 m. Detailed observations of BRE23001-004 will be completed and updates released in due course.
