This area between Nalbi Ditch and Grassina Torrent, east of the built-up area, was exploited along Nalbi Ditch around 1910 (Abresch claim), and several large copper blocks (over 100 kg also) were found.

After WW I, mining works restarted around 1932, and in 1937 six large copper blocks (the biggest of 1750 kg) were found.

Approximately in the same years, mining started along the Grassina torrent; all the workings were abandoned during WW II.
