The Rittersgrün project includes the deposits Hämmerlein, Tellerhäuser (Dreiberg and Zweibach) and Breitenbrunn. Together, they represent one of the most important tin resources in the world.
In November 2019 Saxore applied for a mining licence according to §8 federal mining law (BBergG). This licence was granted in August 2020.
The mining licence area is located in the western Erzgebirge between Schwarzenberg and Oberwiesenthal.
The valuable commodities are tin, zinc, indium and iron.
Mining has been practiced in the region since the Middle Ages.

Within the framework of the Exploration Licence according to §7 Federal Mining Law (BBergG) the sub-deposits Hämmerlein, Tellerhäuser, Breitenbrunn and Antonsthal were explored in the licence area " Breitenbrunn_Indo". Based on historic data the sub-deposits were re-screened, re-evaluated, re-interpreted and finally re-assessed resulting in a new resource model and processing concept. Furthermore, a channel sampling campaign was carried out for the Hämmerlein sub-deposit. The material extracted was analysed, compared with the old data and a test run was carried out in a newly designed pilot processing plant. A re-evaluation of the data showed that the Hämmerlein and Tellerhäuser sub-deposits can be classified as economically mineable at the present time. For Breitenbrunn a more detailed exploration is necessary. The Antonsthal sub-deposit is currently not economically mineable and is therefore not part of the area for which an application has been made.
Based on the exploration work just mentioned, Saxore Bergbau GmbH applied for a mining licence according to §8 BBergG in November 2019 for the mining of state-owned raw materials for the Rittersgrün area. In August 2020 the mining licence was granted. Scoping is currently being prepared. The diagram below shows the further steps in the approval process.
