This article highlights the growing global interest in Mahenge’s rare spinel gemstones, positioning the region as a new frontier for mineral tourism in Tanzania.

Tourism centered on rare spinel gemstones has continued to gain worldwide popularity in Mahenge, an area located in the Ulanga District of the Morogoro region, placing the area on Tanzania’s mineral tourism map.
This was stated by Engineer Penina Mtego, manager of Ruby International Mine, which manages spinel mining in Epanko village.
Engineer Penina explained that the establishment of the Spinel Mineral Tourism Center is driven by the exceptional quality of the minerals, which appear almost laboratory-made. This attracts international gemstone traders, researchers, and various stakeholders to Mahenge to see the actual mining sites and visit special storage facilities.
Engineer Penina explained that spinel from Mahenge is renowned for its unique beauty, particularly its bright pink and red colors, which draw buyers and gem miners from various countries.
Salehe Mbura, who manages the production unit at the mine, said the presence of the mineral has catalyzed a new type of tourism called mineral tourism. Visitors tour mines, learn about mineral formation, and witness traditional mining activities. Others come for business, research, or to visit historical sites related to the mineral’s mining.
Mining Engineer Joseph Ng’itu from the Resident Mining Office, Mahenge Mining Region, explained that spinel mining has not only been a valuable asset for Tanzania but also a bridge connecting mining, trade, education, and tourism. With sustainable management, Mahenge could become a hub for mining tourism in Africa, contributing to social and economic development.
He also added that the center includes a mining museum, a jewellery exhibition, and training programs for small-scale miners.
