RM1767   Gold with malachite and bornite

Bleida Far West, Bou Azzer, Ouarzazate, Drâa-Tafilalet, Morocco

Novelty obtained on my last trip to Morocco (02/2018). These are brilliant aggregates of gold formed by numerous crystals rich in faces, curved faces and disposed on a matrix of quartz. The SEM-EDS analyzes show that this gold contains a small percentage of silver (<1% weight). They are accompanied by fibrous aggregates of malachite and gray bornite crystals. This specimen stands out for the contrast between the brilliant gold and the green/gray matrix. An exceptional piece. Bleida is a mine located on the eastern rim of the Bou Azzer district.
