The Tanzanian government has announced a significant production of Tanzanite worth 3.23 billion Tanzanian shillings (/-) in the Mirerani area of the Manyara Region, covering the period from July to September of this year. The total output was reported to be 274,634.32 grammes. This performance in the first quarter of the 2026/27 financial year is attributed to improved oversight by the Ministry of Minerals and collaboration between mine owners and the Mirerani Mining Authority.
Resident Mines Officer (RMO) George Kaseza shared updates with the Parliamentary Standing Committee on Energy and Minerals during their recent visit to the Tanzanite mines. He reported that official Tanzanite sales generated 148.07 billion Tanzanian shillings (/-) in government revenue during the 2025/26 financial year, which concluded in June. The mining sector collected approximately 1.394 trillion Tanzanian shillings (/-) against an annual target of 1.4 trillion (/-), and aims to reach 1.5 trillion (/-) in the current financial year through enhanced production monitoring to strengthen accountability and reduce revenue leakages.
The introduction of camera-equipped hard hats for mining inspectors earlier this year has improved the monitoring of mining operations. These hard hats allow inspectors to record activities during site inspections and verify mineral production before consignments are sealed. The footage can be used at the ministry level to enhance oversight and transparency. The Mirerani mining area is further secured with 310 closed-circuit television (CCTV) cameras and 573 security lights, within a security wall completed in April 2018. Additionally, the Mirerani mineral market was established in 2021.

Regarding production and valuation, Mr. Kaseza reported that Tanzanite beads accounted for 8,622,049.36 grammes, valued at 95.83 million Tanzanian shillings (/-). Another category of Tanzanite recorded was 20,562.35 grammes, worth 16.73 million Tanzanian shillings (/-). Auctions held in May during the 2025/26 financial year offered opportunities for both small- and large-scale traders to sell their gemstones. For instance, the auction for small-scale traders on May 15 recorded sales of 2,809.31 grammes, while the May 21 auction for large-scale traders recorded 10,174.92 grammes.
Committee Chairperson Subira Mgalu stated that the visit aimed to assess mining, trading, and value-addition activities involving Tanzanite within the security wall. She praised the efforts of the RMO in collecting government revenue from Tanzanite and urged further strengthening of daily operations to ensure the gemstone contributes more to national income.
Elisha Mnyawi, Chairperson of the Manyara Regional Miners Association (MAREMA), appealed to the government to maintain 24-hour operations for the entrance and exit gate to the mining area. Currently, miners are prohibited from bringing work equipment into the area after 6 p.m., a restriction he claims could limit mining activities and reduce potential government revenue.
Samwel Rugemalila, MAREMA Mirerani Branch Chairperson, commended the government’s efforts to improve the mining sector, stating that these initiatives have motivated miners to work toward common goals. Magreth Nelson, a Tanzanite traders’ representative within the Mirerani security wall, also praised the government for reinstating mineral auctions in Mirerani, which have allowed traders to sell gemstones transparently and under competitive pricing conditions.
