Terra Balcanica Drills 1168 g/t AgEq Over 1.35 m At Cumavici Ridge And Confirms New Mineralization Over 600 m Northwest
Vancouver, Nov. 07, 2023 - Terra Balcanica Resources Corp. ("Terra" or the "Company") (CSE:TERA; FRA:UB1) is pleased to announce initial assay results from the Phase II drill campaign confirming continuation of the high-grade Cumavici Ridge epithermal vein within its principal Viogor-Zanik project in Bosnia and Herzegovina.
Highlights
- Drillhole CMV23004 intersected 1,168 g/t AgEq (including 452 g/t Ag, 3.49 g/t Au, and 3.36% Zn) over 1.35 m from 36.2 m downhole (Table 1);
- Successful results from CMV23004 add approximately 50 m strike length SE of previously reported CMVDD002 which returned 816.1 g/t AgEq over 2 m (see company news release dated 22nd October 2022) with mineralization remaining open and untested down-dip (Figures 1 and 2);
- A discovery was made by 600 m step outs to the northwest of Cumavici Ridge where CMV23007 and CMV23009 returned 531 g/t AgEq over 0.75 m and 355 g/t AgEq over 1.10 m, respectively with more 2023 Cumavici Ridge assay intervals to follow shortly.
Terra Balcanica CEO, Dr. Aleksandar Miškovi?, comments: "It is very exciting to continue proving up high grade silver-dominated mineralization this close to surface. The CMV23004 drillhole now confirms over 100 m of continuous high-grade mineralization at the centre of the Cumavici Ridge target. Moreover, the newly detected mineralized structure over half a kilometer to northwest speaks to the lateral extent of this prospect and provides plenty of opportunity for infill drilling to delineate its full scale, width, and grade. Our subsurface 3D geological model has been proven and is continuously refined with each successive drill hole. We are thrilled to highlight the remaining drill results from Cumavici Ridge upon completion of internal QA/QC protocol."

Table 1. Assay results of key mineralized intervals from the preliminary 2023 Phase II Cumavici drillholes. 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$22.60/oz for silver (Ag), US$1.10/lb for zinc (Zn), US$5.44/lb for antimony (Sb) and US$1.00/lb for lead (Pb). *Assumed metal recoveries of 90% Au, 93% Ag, 95% Sb, 94% Pb and Zn are based on published metallurgical tests on analogous intermediate sulphidation epithermal vein deposits.

Ongoing Exploration Program
Exploration efforts at the Viogor-Zanik Project are ongoing with results pending from 5 2023 diamond drillholes at the Brezani skarn system where 2022 results reported 88 m at 0.61 g/t AuEq from surface last year (see company news release dated 24th January 2023). Drilling was focussed on stepping out within the 800 m strike length Au-bearing calc-silicate trend on surface.

QAQC
Half core (PQ3 and HQ3) samples were delivered by truck to ALS Bor, Serbia for sample preparation and analysis at the ALS laboratory Loughrea, Ireland an ISO/IEC 17025:2017 certified testing laboratory. Sample preparation PREP-31BY method was used on all core samples. This involves crushing to 70% less than 2 mm, rotary split 1kg and pulverizing the split to greater than 85% passing 75 microns. Gold was assayed by 30g fire assay with ICP-AES finish (Au-ICP21). Analyses of silver and base metals were completed by highly oxidising digestion with HNO3, KClO3 and HBr (ASY-ORE) and the final solution in dilute aqua regia is determined by ICP-AES (ME-ICPORE). Control samples, comprising certified reference materials (CDN-ME-1811), quarter core field duplicates and blanks were inserted at a rate of 9% and investigated as part of the company's quality assurance and quality control program.
