Röhrerbühel

Tyrol, Austria

Project Overview

The Röhrerbühel Project is situated north of the town Kitzbühel in Tyrol. It covers the east-west extending historic mining area from the Kitzbühler Ache valley to the Reiter Ache valley.
The project contains one of the largest identified and past-producing copper deposits in the country and adds significant precious metals value to Ekometall’s project portfolio.

Project Highlights

  • The Röhrerbühel area has been mined for silver and copper intermittently since the 16th century.
  • Along with its upside exploration potential, it has been estimated in the historical literature that approximately 60,000 tonnes of copper at over 1% Cu ore grade remain in the Röhrerbühel mine. These estimates are non compliant with typical mineral exploration classification standards.
  • Preliminary prospecting identified historical mine shafts as described in the literature as well as visible malachite and iron-rich oxidation.

Area Acess

Presently, this area is mostly covered with dense forests and undergrowth. The village of Röhrerbichl and a rural road can be found within the licence area. Extensions to the current licence are under application to the north and west.

Geographic Coverage

The Röhrerbühel licence area is situated north of the town Kitzbühel in Tirol in a low hilly countryside known as Bühlbach. It covers the east-west extending historic mining area from the Kitzbühler Ache valley to the Reiter Ache valley, a strip 2 km wide and 7 km long.

History

Röhrerbühel represents the most significant copper deposit in the Old Palaeozoic Wildschönau shales, located in the Alpbacher unit (deepest Variscan tectonic unit), and was the most important and largest mining operation in the Kitzbühel area. The deposit is layered parallel to the host rock and extends for over 3 km along strike.

Mining of the Röhrerbühel deposit went to a depth of 900m and produced over 60,000 tonnes of copper. Grades increase with depth – As the mine got deeper, the amount of silver-bearing ore decreased, while the content of chalcopyrite doubled.

“The calculations of the Professor were perfectly correct. We were already six thousand feet deeper down in the bowels of the earth than anyone had ever been before. The lowest known depth to which man had hitherto penetrated was in the mines of Kitzbuhel, in the Tirol, and those of Wurttemberg.”
Jules Verne, “Journey to the Center of the Earth” (1864):

This report documents the field observations conducted during a two-day reconnaissance of the Röhrerbühel licence area, which is under the ownership of Ekometall Exploration Ltd (EMEX). The survey was carried out by Anna Rasch- Christensen and Sabine Husch in August 2023. It also includes historical data related to the mining activities in the region.
