Kelchalpe

Tyrol, Austria

Project Overview

The Kelchalpe Project is located in Salzburg, Austria within the municipality of Aurach. The license area contains the historical Kupferplatte, Kelchalpe, Bachalpe, and Wildalpe mines.
The area is characterized by the presence of structure-hosted chalcopyrite-pyrite deposits in the form of ore beds, veins, and fractures. Historically, the Kitzbühel region has a long and significant mining history dating back to ancient times.

Project Highlights

  • 55 rock chip samples collected to date in initial prospecting and sampling, with initial assay results returning up to 5.56% Cu, 1465 ppm Co, 0.3 g/t Au.
  • Anomalous gold and cobalt never identified in the historical literature or during previous mining activities.
  • License area covers the most productive historical copper mining areas in the Kitzbühel region, including both the Kupferplatte and Kelchalpe mines.

Geographic Coverage

The Kelchalpe Deposit is situated within the municipality of Aurach, on the right slope of the Wieseneggbach valley (Neinavaie et al., 2001). Its strike end extends below the range of hills located between Laubkogel (1760 meters) and the southern Saalkogel (2007 meters).

History

The Kitzbühel area in the Austrian Alps boasts a rich and significant mining history that has profoundly shaped its economic and cultural trajectory. With origins dating back to ancient times, the region’s role as one of the oldest and most important mining centres in Central Europe has been a driving force behind its settlement development and economic prosperity (Heinisch et al., 2015).

Notably, prehistoric copper ore extraction during the Bronze Age laid the groundwork for mining activities that reached their peak during the late Middle Ages and the early modern era. As the centuries progressed, the mines witnessed periods of closure and revival, culminating in the nationalisation of mining operations in the 17th century. By the end of the 18th century, only the Kupferplatte (German for “Copper Plate”), Kelchalpe/Wildalpe, Schattberg/Sinnwell, Gebra-Lanern, Foidling-Hochalpe and Röhrerbühel mines remained as major operations in the Kitzbühel-Jochberg-Hochfilzen area.

The 19th century brought forth more detailed records of production, highlighting the intricate workings of the mines (Heinisch et al., 2015). In 1830, the Kupferplatte mine had a total basic network of 16,579 metres and shafts of 2,243 metres. After the mid-19th century, the Kelchalpe mine reached its greatest extent with a total of 5.5 km and was the most productive copper mine in the entire Kitzbühel area.

Copper and iron ore production gained prominence, between 1930 & 1945, due to increased demand for raw materials. Iron ore was produced at Gebra-Lannern and Foidling-Hochalpe (Heinisch et al., 2015).

 

 

 

Geology

Ore Hosting

Project Hypothesis

  1. It is unlikely the Cu-Au bearing hydrothermal fluids created only the limited known system that was previously exploited.
  2. There are many other structural features parallel to and surrounding the known system. Ekometall expects that there are other Cu-Au systems within the Kelchalpe area that have yet to be discovered.

Phase 2

Community

Following assessment, we do not believe a well-managed underground development here would interfere with the local environment, tourism, or community and could be realistic for future development. Considering especially that many underground operations already exist and operate successfully in the local area.

Impact

Large historic mine waste dumps are a noted source of water pollution, their removal could be of benefit to the local population and environment. The dump material is loose at surface covering a large area, grades up to 3% copper with cobalt and gold credits and is easily accessible by road.

Planned Work Program

The planned work program at Kelchalpe is focused on better understanding this deposit style to best determine grade/tonnage potential as well as optimal drill hole planning.
