Geographic Location

Codera Valley is nestled in the heart of the Alps, within Novate Mezzola, Sondrio Province, in the Lombardy region of northern Italy. This area is about 90 kilometers north of Milan and 35 kilometers west of Sondrio, close to the Swiss border. It's accessible via Novate Mezzola, a small town known for its natural beauty and proximity to Lake Como, making it a scenic spot for mineral enthusiasts.

Minerals Produced

The valley is a treasure trove for mineral collectors, boasting over 100 valid minerals. Notable finds include beryl (with varieties like aquamarine), epidote, muscovite, and spessartine. Rare minerals such as bavenite, becquerelite, and milarite add to its allure, especially for those seeking unique specimens. The presence of LCT pegmatites suggests a rich environment for lithium, cesium, and tantalum minerals.

Geological Structure

Research suggests that Codera Valley's geology includes metamorphic rocks like gneiss, with minerals often found at contact zones between different rock types. LCT pegmatites, igneous rocks formed from late-stage magma crystallization, are also present, contributing to the formation of its diverse mineralogy through complex geological processes.

Mining History

It seems likely that historical mining occurred in Codera Valley, given the presence of economically significant minerals like copper, lead, and uranium. However, specific details on when mining started, methods used, or scale are limited, suggesting it may have been small-scale or focused on specimen collection rather than large-scale operations.
