Why did Johann Wolfgang von Goethe struggle to reopen the Ilmenau silver mine?

Johann Wolfgang von Goethe’s efforts to reopen the silver mine near Ilmenau were ultimately unsuccessful due to two primary factors: the repeated flooding of the mine shafts and the poor quality of the ore that was eventually recovered.1

Tasked by Duke Charles Augustus with the project, Goethe dedicated over 20 years to the endeavor. His work included extensive preparation, such as managing legal requirements, organizing shareholders, securing equipment, hiring expert staff, and conducting personal research into geology and mining. Despite this significant investment of time and resources, the technical challenges of the site and the lack of viable ore prevented the mine from becoming a productive enterprise.1
