Zlata Idka Project (Under Application)

This project is famous for previous silver production. A total of 14 major and several minor veins are known to occur in the ore field, which stretches 9km in strike by 1km in width. Apart from silver and gold, Prospech expects to define significant antimony targets on grant of this tenement.

Ag-Au-Pb-Zn-Sb veins at Zlata Idka are related to granite intrusion of Permian age. Vein are generally striking 70°, strike length of the entire ore field is approx. 9km and width is approx. 1km. Individual veins are up to 1km long, commonly between 200-400m. Vertical extent of the veins is reportedly up to 350m. The veins consist mainly of quartz-siderite, with abundant jamesonite, arsenopyrite, stibnite, chalcopyrite, tetrahedrite, pyrite, sphalerite, etc. Most of the silver is contained in jamesonite and tetrahedite.

Grades from 1912 seems to be too good to be true – Ag – 1300 g/t, Pb – 3.5 %, Cu – 0,3%, Sb – 3%, As 5%, no Au assays. S content in these assays is approx. 9-10 % in average and therefore there is a chance the assays do not represent average production grade, but selective sulphide rich vein material. However, these are again mentioned in a report from 1980 as a typical ore assay. Production records from 1863-1867 indicate Ag: Au ratio 300:1, therefore we assume additional approxiamtely 4 g/t Au credit in the mineralised material.

Silver assays from some of the veins are significant  – Stefan vein reportedly contained 900-7800 g/t Ag on Ludovika adit level, ore from second deep level (570 mRL) contained 4000-5000 g/t Ag.

Frantisek vein is very different from all Zlata Idka veins and contains very low Ag (70-300 g/t). Some stibnite rich parts did not contain any reportable Ag grades. However, quartz rich parts of the vein contained gold up to 5-14 g/t over 0.6-1.3m width.

Whilst general strike of typical Zlata Idka veins is 70°, there was accidentally discovered a single vein striking N-S. This vein was strongly tectonically segmented and therefore drifted for only 8-10m, but the gold grades reported from this vein are 66-90 g/t Au.



L'ubietova Exploration Licence Area (Under Application)

Application has been made, but not yet granted, for the L’ubietová exploration licence area. Located approximately 50 kilometres northeast of the Hodrusa-Hamre licence area, the 14.2km² L’ubietová exploration licence application covers the Podlipa silver-copper-cobalt deposit which has reported historical production of 55 million ounces of silver and 25,000 tons of copper from an oxide zone at shallow depths over its approximate 500 year mining history. A recent academic study has indicated the possibility of mineralisation in the deeper sulphides, making L’ubietová an attractive exploration target at minimal cost to the Company.
