Terra Balcanica Intersects Mineralized Structure With 640 m Step-Out From Cumavici Ridge Polymetallic Vein in Bosnia

05.09.2023 | 14:00 Uhr | GlobeNewswire

Vancouver, Sept. 05, 2023 - Terra Balcanica Resources Corp. ("Terra" or the "Company") (CSE:TERA; FRA:UB1) is pleased to announce the discovery of a new mineralized structure over 600 m northwest from the 2022 discovery made at the Cumavici Ridge epithermal vein target within its principal Viogor-Zanik project in eastern Bosnia and Herzegovina.


  • Shallow, polymetallic mineralization has been intersected over 600 m northwest of the 2022 high grade, silver discovery at Cumavici Ridge through drill testing of a new parallel structure (Figure 1);

  • All 5 drill holes hit the target structure, with drill holes CMV23007, CMV23009 and CMV23010 macroscopically displaying polymetallic mineralization (Figure 2);

  • Step out structure is continuous for 193 m northwest-southeast and open along strike and down-dip;

  • Geochemical assay results from the Phase II drilling at the Cumavici polymetallic prospect are pending laboratory release and will be imminently reported.

Terra Balcanica CEO, Dr. Aleksandar Miškovi?, comments: "The 2023 drill campaign started off on the right foot with a significant step out from the centre of the mineralized zone discovered at Cumavici Ridge in 2022. The footprint of silver-dominated, polymetallic mineralization now extends over 700 m along the NW-SE corridor at this locality, only one of five separate targets along the 7.2 km long Cumavici corridor. The laboratory assays from these step-out drill holes and the central part of Cumavici Ridge are expected to come back shortly. We will continue to carry on further drilling at the Cumavici Ridge target in our Phase II drilling."

The Company commenced its Phase II drilling program at Cumavici Ridge, which was the location of the 2022 high-grade polymetallic discovery which returned up to 505 g/t Ag Eq. over 11 m (see Company news release dated 18th April 2023). Over 600 m to the northwest Drillholes CMV23006-010 successfully discovered another mineralized structure, attesting to the prospectivity of the Cumavici Ridge target. Much of the > 7 km strike length structural corridor remains untested, with several mineralized structures outcropping at surface, offering Terra significant exploration opportunity to discover more polymetallic epithermal veins.

Drill Core Observations
Drill hole CMV23007 is situated 520 m northwest of CMV23001 and targets another shallow structure prospective for polymetallic mineralization. Between 39.1 and 41.8 m a series of fault hosted veins, dominated by radiating aggregates of stibnite are observed within a silicified lapilli tuff.

Drill hole CMV23009 collared 74.0 m northwest of CMV23007 intercepted a zone of sulphide mineralization within a tuffaceous breccia between 39.4 and 45.7 m downhole. Within the mineralized structure there are intervals of complete replacement of the breccia matrix by sulphide and a 10 cm sulphide vein comprising stibnite-sphalerite-galena.

Drill hole CMV23010 stepped 59.0 m west-northwest and intersected a mineralized zone between 83.8 and 90.3 m downhole with aggregates of sphalerite within the structure. A sulphide vein is present at 86.85 m depth consisting of stibnite, banded sphalerite, and galena. Confirmation of sulphide mineralization in CMV23010 extends the Cumavici Ridge system 642 m to the northwest and the system remains open.

Ongoing Exploration Program
Further drilling at the Cumavici Ridge target will be focused on extending strike length towards the northwest from the 2022 drillholes (CMVDD001-004). It is interpreted that where the northwest-southeast structure is intersected by a 2nd order northeast-southwest structure a dilation zone is present, resulting in thicker intervals of mineralization. The down-dip section of the high-grade, polymetallic intercepts released in 2022 will also be tested with further drilling to target the mineralization potential at depth.
