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.

Project Stages

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.

Exploration Licence
An exploration licence according to Federal Mining Law (§7 BBergG) gives the company the right to explore for state-owned raw materials in a defined area. It is the legal instrument for the exploration of potential raw material deposits.
Mining Licence
The mining licence according to §8 Federal Mining (BBergG) gives the company the right to explore and mine state-owned raw materials in a defined mining licence area. For this purpose, the necessary operating facilities may be constructed and operated.
The scoping is a meeting at which the company introduces the project to the Mining Authority and the public bodies involved. The subject, scope and method of the environmental impact assessment (EIA) will then be defined. (Whether an EIA must be carried out is decided on the basis of the screening, a preliminary EIA). In most cases, the regional planning association is invited to identify any deviations from the objectives of regional planning or conflicts and to carry out a regional planning procedure with integrated target deviation procedure.
Regional Planning Procedure
The regional planning procedure is used to coordinate regional planning and measures with each other and with the requirements of regional planning. The aim is to avoid planning mistakes and to reveal planning intentions at an early stage. The legal basis in Saxony is provided by §§15 + 16 of the State Planning Act.
Life of Mine Plan
The Life of Mine Plan gives an overview of a future mining project and sets the framework for future sections to be approved by further operation plans. However, the practical work requires the approval of main operating plans, whose duration generally does not exceed two years. A Life of Mine Plan therefore offers the possibility to present a larger time frame for the project, so that the long-term development of the overall project can be evaluated in advance. In this way, possible negative influences on public safety and order and in particular on the environment can be identified, considered, avoided or compensated for at an early stage.
Environmental Impact Assessment
According to §3 Environmental Impact Assessement Act (UVPG) the environmental assessment includes the identification, description and evaluation of the significant impacts of a project, plan or programme on the objects of protection. They provide for effective environmental prevention in accordance with the applicable laws and are carried out according to consistent principles and with public participation.
