Information overload on the Bleiberg leases
thread no2 !
The Bleiberg Zinc-Germanium-Lead-Fluorite-Cadmium Mine Complex, is considered a world class deposit and consists of 116 exploration licenses totaling 6,582.4 hectares, located approximately 130 kilometers south of the city of Salzburg, Austria. Bleiberg is a well-known, 700 year old, polymetallic zinc, germanium, lead, fluorite and cadmium mine site with first operations more than 2,000 years ago with numerous scientific publications, extensive infrastructure and known mineralized bodies.
The mine was among the top six (6) largest Germanium producers in the world. Germanium is widely used in the electronic semiconductor industry.
I recall someone saying the mine was flooded, well that is partially true and of zero issue for BM8 moving forward. The Eastern part of the structure by general consensus has been mined out to a 900 meters depth and currently also is under water. The western part is accessible without dewatering through the Leopold Erbstollen access adit.
Approx. 1150 km of existing tunnels and several mine shafts, plus other infrastructures
Permitting and EnvironmentalAll exploration and development will be done underground from existing water-free access tunnels. The current plan would be to locate any future production facilities, tailings and waste deposits underground resulting in little to no effect on the surface making for easier permitting process. The main rock type is limestone that completely neutralizes any acid generating sulphides.
It should be noted that water in the eastern portion of the mine complex is used to generate hydroelectricity and the clean water is discharged directly to the environment indicating no problems with water quality.
There are several waste dumps in the area that are the responsibility of the Austrian Government. The Company plans to investigate the possibility of recovering fluorite and other metals from these waste dumps and removing them back underground as a joint work program with the Austrian Government.Information
Multi-Metal Development: Reconnaissance Survey Indicates an Extension of Mineralization at Bleiberg Property, AustriaVancouver, British Columbia--
(Newsfile Corp. - August 8, 2022) - Multi-Metal Development Ltd (TSXV: MLY) (OTC Pink: MLYCF) (formerly American Cumo Mining Corporation) is pleased to announce that it has discovered along strike, several surface exposures of zinc-lead mineralization at its Bleiberg Property in Austria, similar to what has been historically mined.
The new mineralization is exposed between 4 and 12 km beyond the end of the existing underground workings (see figure below). The survey consisted of a series of traverses covering the area of the strike extension of the mineralization. A portable x-ray spectrometer (Bruker S1 Titan) was used to analyze mineralization identified. Out of a total of 162 outcrop locations studied, 28 contained visible zinc-lead mineralization. Six readings were taken at each mineralized location and averaged to give an indication of the possible grade. Results range from 0.41% to 8.24% zinc and 0.34% to 41.48% Pb. Note these results are considered indications only of grade not actual grade, as the spectrometer being used only scans the near surface of the outcrop.
