About Kaludra Project

The Kaludra licence comprises weakly metamorphosed, Carboniferous shales and sandstones with rare limestone interbeds, unconformably overlain by Cretaceous sandstone and Tertiary andesitic tuff. All units are intruded by quartz monzonite and diorite stocks which occur in the north and northwestern parts of the licence. The principal area of interest is in the east of the licence where medieval adits and surficial pits cover an area of 500 x 200 m of outcropping mineralization adjacent to the flysch-limestone contact. Mineralization is hosted in up to 10 m wide, NE striking, steeply dipping, iron oxide filled fracture zones and veins with silica-clay selvedges that appear to terminate at the flysch-limestone contact. The mineralized zone is located approximately 500 m SE of the contact with diorite.

Kaludra Project

Northerly extension of the world class Trepča Pb-Zn-Ag skarn deposit of northern Kosovo with historical production of 60.5 Mt @ 8% Pb+Zn and >158.7 Moz* of Ag as well as the Rudnica Cu-Au porphyry district.

Eastern Kaludra zone features untested polymetallic, vein hosted Pb-Zn-Ag sulfide mineralisation with up to 11% Zn and 118 g/t Ag* from surface samples.

Potential for blind carbonate replacement or skarn style mineralisation associated with the limestone-diorite contact has never been explored.

  • 10 m @ 19 g/t Ag, 0.8 % Pb+Zn and 0.1 g/t Au;
  • 6 m @ 25.7 g/t Ag, 1 % Pb+Zn with the trench terminating in mineralization;
  • 4 m @ 14 g/t Ag, 1.3 % Pb+Zn
  • 4 m @ 11 g/t Ag, 0.7 % Pb+Zn
  • 2 m @ 26 g/t Ag, 1.1 % Pb+Zn
  • 1 m @ 33 g/t Ag, 0.4 % Pb+Zn*

*For full disclosure of exploration information and quoted production, grades, reserves and resources see appendix III of the corporate presentation.

Strong Pb-Zn-Ag soil anomalies coincide with the Paleogene quartz latite volcanism.

Ground IP and resistivity survey revealed strong chargeability drill targets in eastern Kaludra.

$352,000 spent on the project in 2020 advancing exploration and identifying drill targets.
