Terra Balcanica Discovers Gold On Surface At Brezani Target Within Viogor-Zanik Project In Bosnia

2022年08月17日20:58

VANCOUVER, British Columbia, Aug. 17, 2022 (GLOBE NEWSWIRE) -- Terra Balcanica Resources Corp. (“Terra” or the “Company”) (CSE:TERA) is pleased to announce the results of exploration trenching at the Brezani target at its 90% owned Viogor-Zanik project in Bosnia and Herzegovina.

Highlights

  • All composite assays obtained from 4 surface trenches totaling 205 m at the greenfield Brezani target intercepted gold mineralization;
    • Trench BRE_004 returned 32 m at 0.54 g/t AuEq. including 10 m at 1.01 g/t AuEq.;
  • Gold-silver-zinc-copper mineralization is confirmed over a 255 m by 220 m area and open along strike within an 850 m gold-in-soil anomaly;
  • Trenching is centred on a 1.2 km wide magnetic high coincident with a strong conductivity anomaly open at depth; this key geochemical and geophysical target will be drill-tested in the current program;
  • Diamond drilling at Brezani has commenced and assays will be released shortly.

Terra Balcanica CEO, Dr. Aleksandar Mišković, comments:“Brezani is an exciting greenfield target discovered by our team in 2021 based on systematic soil sampling and geophysics. The follow up trenching has confirmed significant gold intercepts at surface that may be part of a much larger sulfide mineralized system at depth, which is implied by a 1.2 kilometer wide magnetic and conductivity anomaly. We have now advanced the Brezani target to the drill-testing stage, and assays from our first hole will be released shortly.”

Table 1. Principal composite assay intervals for the Brezani surface trench samples. Gold equivalents (“AuEq.”) are based on assumed metal prices of US$1,950/oz for gold (Au), US$18.00/oz for silver (Ag), US$4.00/lb for copper (Cu) and US$1.50/lb for zinc (Zn). The calculations assume 100% metallurgical recovery and are indicative of gross in situ metal value. All values are rounded to nearest hundredth except for Cu which is rounded to a thousandth %.

Brezani Target - Introduction

  • The Viogor-Zanik project is located within the Oligo-Miocene Srebrenica Magmatic Complex (“SMC”). SMC is situated at the far northwestern extent of the Serbo-Macedonian Metallogenic Province (“SMMP”). This prolific metallogenic province is host to several world class Au-Ag-Cu-Pb-Zn deposits (Figure 1).The Brezani target is located 8.4 km south of the operating Sase Mine (Figure 2), which is owned and operated by Mineco Ltd., a private mining company. The Sase Mine produces approximately 330,000 tonnes of lead-zinc-silver-gold concentrate per year.
  • Brezani hosts several components of a large magmatic-hydrothermal system. It was a greenfield discovery made by the Company after applying modern exploration techniques over the 2020-2022 period including geochemical, geophysical, and structural analysis.
    • Soil sampling was completed on a 125m x 125m grid and defined a geochemical anomaly for detailed geological mapping. An extensive package of hornfels was subsequently identified in contact with diorite and granodiorite intrusive rocks.
    • Geophysical analysis including 1331-line km airborne magnetic and electromagnetic surveys completed in 2021 identified a 1.2 km magnetic high anomaly that may be a proxy for a much larger mineralized system at depth (Figure 3).
    • Trenches were completed to expose bedrock at the inferred hornfels-intrusive contact. Sphalerite and chalcopyrite bearing calc-silicate hornfels and banded exoskarns are observed coincident with Au-Bi-Te-Zn soil geochemical anomalies, marking a contact metasomatic halo. Sulfides are disseminated and lamination parallel. Pervasively argillic altered volcanics and vuggy silica are noted in the trenches indicating a shallow level of erosion (Figure 4 and 5).

QAQC

Two-meter composite lithic samples were delivered to ALS Bor, Serbia for sample preparation and subsequent wet chemical analysis at the ALS laboratory Loughrea, Ireland, an ISO/IEC 17025:2017 certified testing laboratory. Sample preparation PREP-31BY method was used on all rock samples. This involved crushing 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 returning greater than 10 ppm gold are re-analysed using a 30g fire assay with gravimetric finish (Au-GRA21) and base metals by the four-acid digest ICP-AES analyses termed ME-OG62. Control samples comprising the certified reference material CDN-ME-1501 (Canadian Resource Laboratories Ltd.), field duplicates and blanks were inserted at 3% rate and investigated as part of the company’s quality assurance and quality control program.
