Vancouver, British Columbia, April 11, 2024 (GLOBE NEWSWIRE) -- Terra Balcanica Resources Corp. ("Terra" or the "Company") (CSE:TERA; FRA:UB1) is pleased to provide an update from the Phase I and II exploration drilling within its principal 168 km2 Viogor-Zanik project in Bosnia-Herzegovina.
The Company completed approximately 2,200 m of drilling along a shallow, high grade, silver-dominated, intermediate sulfidation polymetallic Ag-Au-Pb-Zn-Sb vein system at the locality known as Chumavichi . This semi-continuous, 7.2 km-long structural corridor associated with a low magnetic response was previously largely untested by drilling and hosts altered volcanic tuffs and breccias with occurrences of massive Pb, Zn and Fe sulphides.
At the Company's second Viogor-Zanik target of Brezani , Terra discovered a surficial auriferous skarn superimposed on an Ag-Pb-Zn-Au mineralized, NE-shallowing structural system itself overlying porphyry andesites stock from 550 m of depth. The target is characterized by overlapping 1.2 km wide magnetic and EM anomalies with over 700 meters wide Au-Bi-Zn anomaly at surface and banded skarn outcrops with sphalerite and chalcopyrite. Similar geophysical signatures are detected at the 4.1 Moz Au Eq. Rogozna Au-Cu skarn project in SW Serbia. The Company completed approximately 1,200 m of diamond drilling at Brezani with additional assays to be released shortly.
Highlights
Maiden Chumavichi Ridge 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;
Chumavichi Ridge drill hole CMVDD002 intercepted 816.1 g/t AgEq. over 2.0 m;
CMVDD003, an 83-meter step-out from CMVDD001, intercepted a vein interval of 465.5 g/t AgEq. over 8.7 meters, including 1196.6 g/t AgEq. over 2.0 meters, and is open at depth;
The step out drillhole CMVDD005 returned 284 g/t AgEq over 10.0 m including 895.8 g/t AgEq over 2.0 m approximately 50 m west-northwest of CMVDD002;
The Chumavichi Ridge drillhole CMVDD004 along the same drill fence 40 m northeast of CMVDD005 returned 505.3 g/t AgEq over 11.0 m from 43.0 m depth including 3075.4 g/t AgEq (108.5 oz/t AgEq) over 1.7 m;
Shallow, polymetallic mineralization was also intersected 600 m NW of the discovery hole at the Cumavici Ridge where two drill holes through a new parallel structure returned 531 g/t AgEq over 0.75 m (CMV23007), and 355 g/t AgEq over 1.10 m (CMV23009);
The Phase II drillhole CMV23004 intersected 1,168 g/t AgEq over 1.35 m from 36.2 m downhole to add 42 m strike length SE of CMVDD002 with mineralization remaining open and untested down-dip ;
Drillhole CMV23003 intersected 457 g/t AgEq over 4.15 m from 43.85 m downhole and points to a wider down-dip continuation of the high-grade mineralization from the previously reported CMV23004 ;
Drill testing of the 650 m-wide, conductivity high at the centre a 1.2 km wide anomalously magnetic rock volume at Brezani intercepted 0.61 g/t AuEq over 88.0 m (BREDD002) and 0.58 g/t AuEq over 28.6 m (BREDD001). Continuation of this drillhole along same azimuth and dip to depth of 674 m has intercepted a substantial width of low to intermediate sulphidation epithermal mineralization and potassically altered, porphyritic andesites overprinted by chlorite from 550 m depth.
Terra Balcanica CEO, Dr. Aleksandar Mišković, comments: "After a year of systematic targeting followed by approximately 3,400 m of diamond drilling over the last two years, we are proud to lay claims to two precious metal rich, polymetallic discoveries at an emerging European mining jurisdiction. Our systematic high grade silver intercepts from two of the five defined Chumavichi corridor targets are indications of its outstanding potential considering it is located only 7 km west of Mineco's silver mine at Sase. Our recent discovery of similar polymetallic mineralization at Brezani adds further value to this multi-domain target. There, a significant mineralized intercept underlies the previously confirmed auriferous skarn starting from surface and overlies a porphyry system which Terra has been targeting at Viogor-Zanik from the very outset. We believe the potential of our discovery at Brezani is tremendous considering the shallowing of the epithermal mineralization along a presumed fault to northeast and stratigraphic intercept below the boiling horizon which will be targeted by our future drill programs. Collectively, this is a thrilling development for Terra as we aim to release assay results from additional five drill holes at Brezani and prepare for a continued definition of this massive magmatic-hydrothermal system in eastern Bosnia"
Upcoming Results
Laboratory assays results from section of drill hole BREDD002 below 215 m depth are pending QA/QC verification and will be released imminently. Additionally, four more diamond drill holes (BRE23001-004) between depths of 120 and 160 m that tested the surface gold bearing calc-silicates and magmatic breccias will be released in comings months.
