VANCOUVER, British Columbia, Aug. 23, 2022 (GLOBE NEWSWIRE) — Terra Balcanica Resources Corp. (“Terra” or the “Company”) (CSE:TERA) is pleased to announce an intersection of massive polymetallic sulphide vein at the Cumavici target located within its 90% owned Viogor-Zanik project, Bosnia and Herzegovina.

  • The first diamond drillhole (Drillhole CMVDD001) completed by the Company at the Viogor-Zanik project discovered a shallow polymetallic, epithermal vein at the Cumavici target located in the NW sector of the project (Figure 1)
  • Massive sulfide veins were intercepted as shallow as 29 meters depth; two intervals of massive sulfide veining dominated by colloform banded sphalerite, galena, and stibnite;
  • Cumavici vein system is over 7.2 km in length and open along strike and down-dip;
  • Assays from current drilling will be released shortly

Terra Balcanica CEO, Dr. Aleksandar Miskovic, comments:

“The presence of a shallow, polymetallic, massive sulphide, vein-hosted system at Cumavici confirms our detailed targeting over the past 20 months. The Viogor-Zanik projects hosts epithermal and porphyry targets that are being tested by our inaugural drill program. Cumavici is a 7.2 kilometers zone of mapped intermediate sulfidation veins and our focus is to define the extents of the mineralized footprint. We are eagerly awaiting the laboratory assays which should be released shortly.”

Target Introduction: Cumavici

Cumavici is an intermediate sulfidation, epithermal vein system situated 6.2 km northwest of the Company’s Olovine target, and 6.7 km west-northwest of the operating Sase Mine (owned and operated by Mineco plc.) which produces approximately 330,000 tonnes of lead-zinc-silver-gold concentrate per year. Cumavici has been defined as a 7.2 km northwest-southeast corridor outlined by structural mapping, soil geochemistry, and geophysics.

Surface sampling at Cumavici conducted by the company over the past 18 months illustrated the potential for high-grade, laterally extensive system. A rock chip sample 100668 collected ca. 3 km SE of CMVDD001 yielded 0.327 g/t Au, 31.7 g/t Ag, 2.2% Pb and 20.1% Zn.

Drill Core Observations – CMVDD001

Drill hole CMVDD001 confirmed the presence of a polymetallic vein system and

intercepted two distinct zones of sulphide veining within Miocene volcanic breccias. Intervals of sulphide-cemented hydrothermal breccia commences at only 29-meter depth.

Vein-hosted, microcrystalline colloform banded sphalerite and coarse galena is present at 31 meters followed by massive stibnite, sphalerite, and breccia to 32 meters. Sulphide veinlets extend into the footwall to 33 meters depth and a further zone of disseminated sulphide is present from 43 meters to depth of 48 meters. Banded veins indicate sustained fluid flow through structures, with additional fluid pervasively altering and precipitating disseminated massive sulfides within the andesitic tuffs and volcanic breccias.

Textural information points to sustained, polyphase fluid flow through the targeted structure which remains open along strike and depth.

Current Drill Program

Hole CMVDD001 was designed to test the presence of a NW-SE striking vein system and dipping to the SW with the regional structural trend. There are numerous planned step-out pad locations to the NW to test the system along strike.

Future drilling efforts will test the continuity of the polymetallic vein system along strike and down dip (Figure 3). Additionally, Terra Balcanica continues to generate drill targets within various sectors of the prospective Cumavici corridor for further shallow polymetallic vein intercepts to the NW and SE.
