FINAL DRILLING RESULTS - ZEMPLIN SILVER - PHASE 2 | |
Zemplin Phase 2 drilling has completed six holes for 2,050 metres with results | |
For personal use | up to 0.5m @ 516 g/t Ag |
Tested strike and depth potential of previously discovered, high-grade | |
mineralisation (up to 1,220 g/t silver) | |
Results now reported for holes CZDD007 to CZDD010 | |
Drilling was designed to test the strike and depth potential of a fully preserved
silver and base metal mineralised system.
The Directors of Prospech Limited ('Prospech' or 'the Company') (ASX: PRS) are pleased to advise that Phase 2 drilling has been completed at the Zemplin silver-lead-zinc prospect within the Cejkov- Zemplin exploration licence, located in the Eastern Slovakian neovolcanic belt.
Level 2, 66 Hunter Street, Sydney NSW 2000 Australia

This program follows Prospech drilling in April 2021, which intersected over 40 epithermal veins hosted within zones of hydrothermally altered volcanics. The Zemplin structure consists of parallel zones which remain open to the northwest and southeast. The main silver zone is now interpreted as being a narrow series of parallel structures.
Results from the Phase 2 drilling include:

Prospech Managing Director Jason Beckton comments:
"An open, high grade zone, albeit narrow, at the Zemplin prospect epithermal vein system has been discovered in CZDD009 which is above the magnetic zone as currently interpreted and partially tested by CZDD010. Further drilling along strike from this high grade zone, to the south west of the Zemplin project, will be evaluated in conjunction with drilling results from the current drilling program at the Hodrusa project."
