Project Olza hosts a Mississippi Valley type zinc-lead deposit.

The property comprises three adjoining Exploration Concessions for the prospecting and exploration for zinc and lead ores. The Zawiercie, Rokitno, and Chechlo concessions are approximately 60 km northwest of the city of Krakow in southern Poland, and have a total surface area of 152.65 km2 .

The Project is within the North European Plain, a relatively flat area with an average elevation between 300 to 350 m above sea level. Within the project area, there is land available for potential surface facilities to support a proposed underground mine and associated processing infrastructure.

Project Olza lies within the Upper Silesian Mining district, near the boundary between the Caledonian Krakow-Myszkow structural zone and the Variscan Upper Silesian coal basin. Zinc and lead deposits in Upper Silesia are principally hosted by dolomites of the Middle Triassic Muschelkalk Formation but locally zinc and lead mineralization also occurs in older rocks, including Devonian limestone and dolomite. In the southwestern part of the district, the Triassic host rocks overlie Upper Carboniferous Coal Measures. However, in the northeastern part of the district, where Project Olza is located, the Triassic rocks transgressively overlap the erosional paleosurface of the Lower Carboniferous and Devonian carbonates, and the PermoCarboniferous strata are missing. Below this succession lie Lower Paleozoic ........

The proposed approach in the PEA considers mining the Olza zinc and lead deposit at a target production rate of 6,000 tonnes per day (“tpd”) or 2.16 million tonnes per annum (“Mtpa”) using variations of underground Room and Pillar (“R&P”) methods with an unconsolidated coarse sand backfill. The sand fill will be contained within rock pillars and timber barricades and is expected to fill fairly tight to the backs of the stopes. The coarse sand is sourced from local quarries and will be transported to the Olza Process Facilities at the site of the historic cement plant via rail.

The mine would be accessed by two declines, and mined material would be moved to the surface by a conveyor along one of these declines.

To facilitate underground access and to expedite the construction schedule two separate declines will be constructed. A decline will be driven from the proposed site of the process plant to intersect with the main haulage drift. This decline ‘CD1’ would be excavated to sufficient width to accommodate a conveyor. A second decline ‘TD1’ would be driven in close proximity to the main portion of the currently defined resource. This second decline would be used for transport of men, equipment and materials to expedite the underground development.

A 3D geological model created to understand the orientation of the mineralization and the spatial variability of the resource drilling shows the mineralization is sub horizontal to shallow dipping ± ........
