Terra Balcanica Resources Corp. announced additional, positive step-out drill results at the high-grade polymetallic Cumavici Ridge epithermal target within its, 216 km2 Viogor-Zanik project, Bosnia and Herzegovina. Highlights High grade +50 m step out: Drillhole CMVDD005 returned 284 g/t AgEq over 10.0 m including 895.8 g/t AgEq over 2.0 m approximately 50 m west-northwest of CMVDD002; Previously released intercepts at the Cumavici target returned similar high grades: CMVDD001: 824.2 g/t AgEq.

over 4.0 m including 1634.4 g/t AgEq. over 2.0 m; CMVDD002: 816.1 g/t AgEq. over 2.0 m; CMVDD003: 465.5 g/t AgEq.

over 8.7 m including 1196.6 g/t AgEq. over 2.0 m; CMVDD004, located 40 m northeast of CMVDD005, intersected 11 m of visible sulphide mineralization with assays to be released shortly; Exploration upside: CMVDD005 confirms consistent high grade, polymetallic mineralization at Cumavici Ridge. The mineralization is entirely open to the NW and down-dipto the SW.

High-grade results confirm the Cumavici corridor as a shallow, polymetallic epithermal discovery with significant potential for expansion. Drillhole CMVDD005: targeted the down-dip extension of the lateral step out confirmed by CMVDD004 with a 40 m collar location step out to the west-southwest. CMVDD005 intercepted 2 mineralized intervals, evidencing the branching nature of the main Cumavici vein including 285 g/t AgEq over 10 m from 81 m. Mineralization consists of massive sulphide veins and breccias cemented by quartz, calcite, sphalerite, galena, and stibnite.

Drillhole CMVDD006: successfully intercepted a continuation of the mineralized Cumavici structure 125 m to the SE from CMVDD005. Mineralization was disseminated, in broad zones of fault gouge and breccia indicating a pinching and swelling nature to the massive sulphide zones. An association of sulphides and brecciated calcite within the clay gouge is noted, possibly due to precipitation of the mineralization during active fault movement.

Further Drilling: Assay results from CMVDD004, which intersected 11 m of visible sulphide mineralization from 43 m depth will be released shortly. Other assays to be released include drill testing of the Joseva target, which is 2.3 km to the SE of Cumavici Ridge. The 2023 drill program will systematically test the high-grade Cumavici vein along strike to the NW/SE and down-dip SW where the mineralization is open and untested.
