News Release Video: Terra Balcanica produced a technical webinar to explain the drill results

Terra Balcanica Resources Corp. (CSE:TERA) (FRA:UB1) is pleased to announce the final geochemical assay results from the Phase II drill campaign at Cumavici Ridge confirming continuation of the high-grade epithermal vein mineralization at the Viogor-Zanik project in Bosnia and Herzegovina.

Highlights

• Drillhole CMV23001 intersected 551 g/t AgEq over 4.8 m from 11 m downhole with a further mineralized interval of 669 g/t AgEq over 0.3 m from 31.60 m (Table 1);
• Drillhole CMV23001 is located on the same platform as previously CMV23002b which returned 499 g/t AgEq over 3.8 m from 22 m reported (see Company news release 17 January 2024);
• The Cumavici Ridge mineralization remains open and untested immediately northwest and down-dip to the southwest, which will be targeted by our 2024 Phase III drill program;
• Further assay results from the 2023 Phase II drilling program are pending release, including 4 shallow drillholes at the Brezani Au skarn, which aim to add strike length to the previously reported 88.0 m at 0.61 g/t AuEq from surface (news release dated 24 January 2023).

Terra Balcanica CEO, Dr. Aleksandar Mišković, commented: “Terra keeps on confirming average grades of over 500 g/t Ag Eq and average mineralization thicknesses of approximately 5-10 m of massive sulfides and associated Ag-Sb-Pb-Zn-Au mineralogy at Cumavici Ridge which is only one of six target zones along the 7.2 km corridor of vein-hosted epithermal mineralization. This zone is de-risked by drilling shallow, high grade silver mineralization at both the Cumavici Ridge and Joseva targets over 2.3 km apart. We are very excited to carry on adding to the existing mineralized horizon at Cumavici Ridge by testing it down dip to SW as well as along strike to NW while expanding drill campaign to Cumurnica and two other targets along the corridor in 2024.”

Table 1. Assay results from drillhole CMV23001 of the Phase II drilling campaign. Interval lengths reported are drilled lengths, not true widths. Silver equivalent (“AgEq”) is based on assumed metal prices of US$1,980/oz for gold (Au), US$23/oz for silver (Ag), US$1.15/lb for zinc (Zn), US$5.42/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.

AgEq values are labelled for selected 2022 and 2023 drill intercepts (See Company’s new releases dated 13 November 2023, 27 February 2023, 17 January 2024). Current drilling efforts confirm mineralization over 82 m NW/SE strike length. (WGS84/UTM Zone 34N)

Future Exploration Program

Further drilling efforts at Cumavici Ridge will aim to connect the shallow high-grade interval reported in this release to the 531 g/t AgEq over 0.75 m and 355 g/t AgEq over 1.10 m reported over 600 m to the northwest (see Company news release dated 5^th November 2023). The shallow, vein hosted system remains untested and open to the southwest down-dip which will also be targeted during the 2024 Phase III drilling.

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.
