News Release Video: Terra Balcanica produced a technical webinar to explain the drill results
Vancouver, British Columbia, Jan. 20, 2025 (GLOBE NEWSWIRE) -- Terra Balcanica Resources Corp. ("Terra" or the "Company") (CSE:TERA; FRA:UB1) is pleased to announce strong assay results from a new discovery at the Brezani target within its principal Viogor-Zanik project in eastern Bosnia and Herzegovina.
Highlights
- Drillhole BREDD002 returned 436 g/t AgEq over 19.6 m including 746 g/t AgEq and 1.42 wt.% Sb over 9.8 m;
- Another mineralization style confirmed at Brezani in addition to the gold skarn with 0.61 g/t AuEq over 88.0 m from surface (see Company's news release dated 24th January 2023);
- Mineralization trends towards surface and daylights in a topographic depression with As-Bi-Sb-Te anomalism in soil samples with a shallow "boiling-zone" drill target (Figure 1);
- 4 shallow drillholes, aimed at expanding the footprint of the gold skarn have been completed within the > 800 m strike length gold in soil anomaly, with assay results pending.
Terra Balcanica CEO, Dr. Aleksandar Miškovic, comments: "We are very pleased with the polymetallic assays from an interval thrice as wide as that average reported at our other Viogor-Zanik target at Cumavici. Not only have we discovered a new type of mineralization that shallows toward northeast, and as such could be easily explored from top down, but we have also confirmed the significant presence of antimony at Brezani which continues to be a scarce commodity worldwide due to supply issues and trade restrictions imposed on certain countries. Now, the drill-confirmed surficial Au bearing skarn is confirmed to be underlain by the significant fault-hosted polymetallic mineralization which itself is underpinned by andesitic porphyry. It is encouraging to see this resulted from the very first drill hole leaving a lot of upside potential at Brezani as Terra releases additional assays from the four shallower intercepts drilled into the surficial skarn."

Table 1. Assay results of the new epithermal discovery in drillhole BREDD002. Interval lengths reported are drilled lengths, not true widths. Silver equivalents ("AgEq") are based on assumed metal prices of US$2,700/oz for gold (Au), US$30/oz for silver (Ag), US$1.40/lb for zinc (Zn), US$17.50/lb for antimony (Sb) and US$0.90/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. The Sb pricing derived from the Nov. 2024 average Rotterdam Warehouse 99.6% ingot price.

Drillcore Observations
The zone of mineralization from 482.1 m consists of banded veins and sulphide cemented breccias with characteristics of both low and intermediate sulphidation epithermal deposits. The upper vein contact is sharp with minimal alteration progressing into the hornfels, whereas the vein footwall is brecciated and hosts strong clay alteration. The margins of the vein host repeating bands of chalcedonic quartz-rhodochrosite-calcite and sulphides/sulphosalts stibnite-pyrite-arsenopyrite-sphalerite-galena-jamesonite (Figure 2). The centre of the structure is dominated by hydrothermal breccia with a sulphide-quartz-carbonate cement. Clasts are banded vein fragments.
Figure 1. Section through the Brezani target illustrating conductivity and the 95th percentile magnetic shell. Drillhole BREDD002 is shown, with a tabular conductivity feature extending to the ENE from the epithermal mineralized interval. Conductivity feature is interpreted as the continuation of the host structure with increased conductivity due to sulphide and clay within the broken rock mass. It passes through a break in the magnetics, which is further evidence of structural control (click here to view image).
Future Exploration Program
The 2023 drilling at the Brezani target uncovered a new style of mineralization at the contact between the skarn-hornfels package and underlying chlorite-sericite altered diorites. The epithermal mineralization encountered 482.1 m downhole is interpreted to shallow to the ENE creating a conductivity feature which passes through a magnetic low. A topographic low with an anomalous epithermal assemblage in soil and rock chip geochemistry is interpreted as the surface expression. Future drilling efforts will aim to intersect the epithermal mineralization shallow and explore for a "boiling zone" where precious metals may have been favourably precipitated.

QA/QC
Half core (HQ3) samples were delivered to ALS Bor, Serbia for sample preparation and subsequent wet chemical analysis at the Loughrea laboratory in Ireland, an ISO/IEC 17025:2017 certified test facility. Sample preparation PREP-31BY method involved crushing the core to 70% less than 2 mm, rotary split 1.0 kg and pulverizing the split to greater than 85% passing 75 microns. Silver and base metals were analysed by ICP MS after a four-acid digest (ME-MS61). Gold was assayed by 30g fire assay with ICP AES finish (Au-ICP21). Over limit samples for base metals were re-analysed by the four-acid digest ICP-AES analyses termed ME-OG62. Control samples comprising the certified reference material CDN-ME-1810 (Canadian Resource Labs Ltd.), 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.
