A small ancient mine working a Ni deposit west of the town of Lavrion, situated close to the "Km 3" milepost on the road from the town of Lavrion to the village of Agios Konstantinos (formerly Kamareza), around 2.5 km from each.

One of the most famous localities within the Lavrion district, known for the world's best annabergite specimens, with bright green crystals reaching 1 cm. Most well-crystallized specimens are the Mg-rich variety termed "cabrerite" (obsolete name), showing bright apple-green color.
Specimens can still be found in the dumps.

This locality actually consists of several individual places where different minerals can be found. A planned future revision will separate these into distinctive localities.

Notes on the mineral list: Glaukosphaerite has been described by Schnorrer & Breitenbach (1996). However, specimens of "glaukosphaerite" from this locality which have been fully analysed have turned out to be rosasite. It is therefore in doubt whether most of the glaukosphaerite in collections actually are correctly identified.
