🇲🇬 MADAGASCAR –
Nosy Be Region Mining Project
Project Status: Completed in 2005
Start Year: 2002
Minerals: Sapphires, Garnets, other gemstones
Mining Type: Alluvial
Technology: DOVE EXPLORER® modular processing plants, specially engineered with a fully contained water circulation system in tanks to comply with strict environmental restrictions in the region.
Project Description
In 2002, DOVE expanded into the Nosy Be region, a volcanic island in northwest Madagascar, known for its unique geology and gem-bearing alluvial gravels.
The project reflected DOVE’s commitment not only to gemstone recovery but also to environmentally responsible mining practices. By deploying EXPLORER® plants with closed-loop water circulation, DOVE ensured compliance with local environmental protection standards, minimizing ecological impact while maintaining high recovery efficiency.
Gemstone Characteristics
Nosy Be’s deposits produced:
- Sapphires (blue and fancy colors)
- Garnets
- Other secondary gemstones
While smaller in scale compared to Antsiranana and Ilakaka, the Nosy Be sapphires were of notable quality, and the sustainable mining model showcased DOVE’s leadership in responsible gemstone mining.
Joint Venture Development
To enhance the project’s scope, DOVE entered into a joint venture with Canalta Gems (Canada) Inc.
DOVE–Canalta Gems (Canada) Inc. Sapphire Mining Operation
- DOVE provided: Licensed mining block, EXPLORER® processing plant, and full technical expertise.
- Canalta Gems provided: Investment and international marketing access.
This collaboration successfully produced commercial volumes of sapphires, further strengthening Madagascar’s reputation as a responsible and leading source of gemstones.
