Olza Project in Poland
  • Established Mining District

  • Structured, clear & transparent mine permitting process

  • Good Upside Potential


Rathdowney Resources Ltd. is a Canadian publicly-traded company (TSXV:RTH) whose primary focus is developing and permitting its flagship, 100%-owned Olza zinc-lead-silver development project in Poland.


Located in the Upper Silesian Mining District of Poland, historical drilling indicated the presence of extensive Mississippi Valley-Type zinc-lead deposits in the project-area, which has been confirmed as a result of Rathdowney's work.

Drilling programs have led to estimates of significant mineral resources at Project Olza, with excellent potential for expansion across the large property. Preliminary metallurgical testwork on Olza mineralization showed that standard flotation will result in high quality zinc and lead concentrates. 

Rathdowney's current work is designed to advance project evaluation and development planning, and to support permitting as outlined for projects in Poland. Baseline environmental data collection is well-advanced and engineering studies are progressing.

Rathdowney is associated with Hunter Dickinson Inc. (HDI), a diversified, global mining group with more than 35 years of demonstrated success in finding mines worldwide.

Project Olza

Olza is located in Poland's Upper Silesian Mining District, a region of world-class Mississippi Valley-Type zinc-lead deposits, which has a supportive and vast mining history. Olza is located north of the nearby Pomerzany Mine that produced +90 Mt over 40 years to 2020. The district is home to a local skilled workforce and well-established infrastructure that would support mine development. Power and housing are locally available. A railway line runs through the Olza project-area, linking it to the ZGHB smelter (about 25 km from the site) and to ports on the Baltic Sea, providing access to smelters in the rest of Europe.


Extensive prior drilling and historical estimates by the Polish State Geological Institute ("PSGI") indicated substantial zinc-lead deposits with the potential for significant resources in the Olza area. Rathdowney drilling in a small portion of this area (~30% of historical resource) produced an inferred resource of 24.4 Mt of 7.02% Zn+Pb (5.53% Zn and 1.49% Pb), which formed the basis for a Preliminary Economic Assessment ("PEA") announced in 2015.


​The company plans to update the PEA as financing is available.
