Fireweed secures US, Canadian gov’t fundings for tungsten project
The US Department of Defense invested about $15.8 million under the Defense Production Act.
Vancouver, British Columbia, Jan. 11, 2023 (GLOBE NEWSWIRE) -- Terra Balcanica Resources Corp. (“Terra” or the “Company”) (CSE:TERA, FSE:UB1) is pleased to confirm that step-out drilling has extended the massive, polymetallic sulphide vein system at the Cumavici Ridge target located within its 90% owned Viogor-Zanik project, Bosnia and Herzegovina.
Highlights
Terra Balcanica CEO, Dr. Aleksandar Mišković, commented: “The 2022 maiden drill program at Cumavici Ridge has been encouraging in confirming the hypothesis of identifying a shallow, high-grade polymetallic, epithermal vein-hosted mineralized system, while also confirming its down-dip and along-strike continuity. It is very exciting to see the Cumavici Ridge target entirely open along strike allowing for continued step out and infill drilling. Our team has gained a strong understanding of the local geology and there are a series of targets that will be tested to expand the mineralized system. We see the same macroscopic features in these holes as we did in the previously released drillholes and eagerly await the assay results which are expected shortly.”
The Company commenced its maiden drill program by discovering a high-grade, polymetallic vein system intercepting 824.2 g/t AgEq over 4.0 m at the Cumavici Ridge target (see news release dated September 8, 2022). Subsequently, the footprint of this intermediate sulfidation epithermal system was extended 83 m down-dip including drill intervals of 465.5 g/t AgEq over 8.7 m, including 1196 g/t AgEq over 2.0 m (see Company news release dated October 22, 2022). The subsequent step-out holes of CMVDD004 and CMVDD005 have intercepted thicker intervals of up to 11 m of massive sulphides approximately 50 meters west-northwest from the initial cluster of drillholes including CMVDD001, CMVDD002 and CMVDD003.
Drill Core ObservationsCMVDD004 – Drillhole CMVDD004 intercepted approximately 11 m of altered andesitic tuff and visible sulphide-rich veining starting from 43 m depth. Over 1.7 m of semi-massive sulphides are observed from 44.8 m dominated by stibnite with sphalerite and galena. In the footwall, stockwork veinlets grade into disseminated sulphides in a pervasively argillic-altered volcanic.
CMVDD005 – Drillhole CMVDD005 intercepted two distinct zones of continuous sulphide veining within andesitic crystalline tuffs. At 34.4 m depth a 0.3 m massive sulphide vein is observed dominated by stibnite with lesser sphalerite and galena within a 3 m-wide zone of Ag-Zn-Pb mineralization. A second zone of massive sulphide veining approximately 10 m wide is encountered from 81.0 m depth comprised of sulphide cemented breccias, quartz-sulphide veins and intervals of massive sulphide, which grades downhole into sporadic aggregates of stibnite and sphalerite.

Ongoing Exploration Program
Drillhole CMVDD004 represents an approximately 30 m northwest lateral step out from CMVDD001. The down-dip extension of this is confirmed with CMVDD005 with a collar separation of approximately 50 m between end holes on the two drill fences. Future drilling efforts will test the continuity of the 7.2 km long Cumavici polymetallic vein system along strike towards the northwest and southeast. Additionally, the Company completed drilling at the Brezani skarn/porphyry target which is located over 12 km to the southeast from Cumavici (see Figure 1).
