New Almaden hydrothermal deposition of cinnabar from deep within the earth is found in a gangue of silica-carbonate rock formed locally by hydrothermal alteration of serpentine. The Guadalupe mine produced about 10% as much mercury as the New Almaden. There are several smaller mines in the mining district, but their ore production was not significant. The only significant quicksilver ore is cinnabar; other sulfides are present in small quantities. Mining, other than a single placer deposit of cinnabar, was underground. There is a high probability of undiscovered high-grade ore which could be found and exploited using modern techniques. Mining operations resulted in
Wooden toymaking in the Ore Mountains Wooden toymaking in the Ore Mountains The history of wooden toymaking in the Ore Mountains is closely bound to regional circumstances. The Ore Mountains are located in Central Europe on the border between Germany and the Czech Republic. For many centuries it was a countryside in which the local population eked out a hard existence from the land. Long and harsh winters restricted agriculture; in addition the region had very poor communications. With the onset of ore mining a new line of commerce developed, but the hard labour and high risks involved meant that it was only work for young
