Vancouver, British Columbia - 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.
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.
