EXPLORATION AND SAMPLING
airborne EM methods, particularly for Archean lode-gold deposits whose disseminated sulphide nature and attendant quartz-potassiccarbonate alteration cause them to be virtually undetectable electromagnetically. Yet many examples of successful VTEM and ZTEM applications for gold exploration exist from around the world.”
Beak further develops predictive software
In 2016 / 2017, Beak Consultants GmbH further developed its advangeo ® product family to satisfy the rising demands of big data storage, data processing and data distribution.“ The artificial neural network based advangeo ® Prediction Software was completed by implementing the alternative method of fuzzy logic as knowledge based approach. New functionalities have been added to verify the reliability of predictive results, including statistics and network connection weight analysis. They considerably support the analysis and understanding of complex geological processes and relationships, like interaction of various mineral deposit forming processes and tectonic and lithological traps.”
Data distribution and communication is now supported by advangeo ® Online with internetbased file sharing with automatic payment procedures using common credit cards. This approach eases the purchase of data, like geological maps and any geochemical or geophysical dataset. Respective features were implemented on behalf of the Geological Survey of Tanzania( www. gstdatashop. com, www. gmistanzania. com).
The neural network based advangeo ® 3D Prediction Software was successfully implemented and tested with big datasets from the German Erzgebirge( 150 km x 40 km x 2 km) with 100 m resolution. Tin exploration targets have been generated. The software interacts with arbitrary 3D datasets generated by using any common 3D modelling software( eg Surpac, Leapfrog, GOCAD).
Beak’ s advangeo ® Field Cap software further supports the capture and initial processing of geological field data including sample parameters for hard material, water, streamsediment and soil samples. The implementation of web-based mapping services together with inbuilt GPS receivers help to quickly and easily

orientate during fieldwork. The field tablet application communicates with server software allowing the co-operation and data exchange of bigger field teams. Recently, a software solution was adjusted to the needs of the Geological Survey of Namibia.
Beak Consultants GmbH is also a part of important Federal and Saxonian research projects like WISTAMERZ and ROHSA3 helping to develop new approaches in sustainable
