Terra Balcanica Confirms Cumavici Vein Discovery And Reports 824.2 g/t Silver Equivalent Over 4.0 Metres Within Its Viogor-Zanik Project In Bosnia


Vancouver, British Columbia, Sept. 08, 2022 (GLOBE NEWSWIRE) -- Terra Balcanica Resources Corp. (“Terra” or the “Company”) (CSE:TERA) is pleased to announce the results of its maiden drilling at the Cumavici prospect at its 90% owned Viogor-Zanik project, Bosnia and Herzegovina. The Company intercepted a shallow, high-grade polymetallic vein with the first drillhole completed on the project.

Highlights

  • Discovery of shallow, high-grade, polymetallic, vein-hosted mineralization;
  • Drillhole CMVDD001 intercepted 824.2 g/t AgEq. over 4.0 m from 29 m of depth, including 1,634.4 g/t AgEq. over 2.0 meters;
  • Results confirm the shallow nature of the Cumavici corridor where much of the 7.2 km NW-SE strike length remains untested;
  • Over 1,000 meters of assays are pending from the Cumavici target area; further assays will be released over the coming month and a half.

Terra Balcanica CEO, Dr. Aleksandar Mišković, comments: The intercept of the Cumavici vein is an important milestone for Terra Balcanica after over 18 months of systematic surface geology and drill target generation. High grade polymetallic assays close to surface confirm the macroscopic observations of massive Pb-Zn-Sb sulfides and warrant down-dip as well as along-strike step outs to delineate the size of this epithermal system. As an early mover in Bosnia and Herzegovina, we are looking forward to following the success of Adriatic Metals in applying modern exploration in an underexplored country with prospective ground. We eagerly await assay results from additional drill holes which will be reported once received.”

Table 1. Assay results of key mineralised intervals for diamond drillhole CMVDD001. Interval lengths reported are drilled lengths, not true widths. Silver equivalents (“AgEq”) are based on assumed metal prices of US$1,950/oz for gold (Au), US$18.00/oz for silver (Ag), US$1.00/lb for lead (Pb), US$4.50/lb for antimony (Sb) and US$1.50/lb for zinc (Zn). The calculations assume 100% metallurgical recovery, indicative of gross in situ metal value.

CMVDD001: Results corroborate observations of colloform banded sphalerite-galena-stibnite with high grade Ag-Au-Pb-Zn-Sb mineralization. Detailed observations and photographs of the mineralized interval were reported in the Company’s news release dated August 23rd, 2022.

The Company is continuing to test the mineralization down dip and along strike thus building the geological model around the high-grade Ag-Au-Pb-Zn-Sb target.

QA/QC
One metre long, composite core samples were delivered to ALS Bor, Serbia for sample preparation and wet chemical analysis at the ALS Loughrea, Ireland, an ISO/IEC 17025:2017 certified laboratory. Sample preparation PREP-31BY method was used on all core samples by crushing to 70% less than 2 mm, rotary split 1 kg and pulverizing the split to greater than 85% passing 75 μm. Gold was assayed by 30g fire assay with ICP-AES finish (Au-ICP21). Over limit samples returning > 10 ppm gold are re-analysed using a 30g fire assay with gravimetric finish (Au-GRA21). Analyses of silver and base metals were completed by oxidising digestion with HNO3, KClO3 and HBr (ASY-ORE), with the final solution in dilute aqua regia determined by ICP-AES (ME-ICPORE). Control samples, comprising certified reference materials (CDN-ME-1811), field duplicates and blanks were inserted at 5% rate and investigated as part of the Company’s quality assurance and quality control program.
