The Tanzanian mining landscape has entered a sophisticated new era of exploration following the launch of a state-of-the-art airborne geological survey helicopter by Barrick Gold in partnership with the state-owned Twiga Minerals.
This strategic deployment in the northern region of Shinyanga is designed to leverage high-resolution geophysical data to identify new deposits while significantly reducing the environmental footprint of traditional ground-based prospecting. The initiative aligns with the government’s “Minerals Vision 2030,” which seeks to transition the nation’s mineral wealth into a diversified pillar of industrial growth.
The technological upgrade arrives at a moment of unprecedented fiscal strength for the sector, with Central Bank data revealing that gold export earnings surged to a record $4.7 billion in the year ending November 2023. By utilising advanced sensors to map subsurface rock formations from the air, Barrick aims to streamline operations across its extensive Lake Zone portfolio, covering key exploration blocks in Nzega, Igunga, Msalala, and Nyanghwale. This move is expected to enhance the accuracy of mineral prospecting, ensuring that capital-intensive deep-drilling projects are directed only at the highest-probability targets.
Minister of Minerals Anthony Mavunde characterised the move as a historic milestone for the country’s scientific research capabilities. “This is a major step for Barrick, in collaboration with the government-owned Twiga Minerals, to conduct more scientific research aimed at expanding the scope of new exploration areas and investment in the country’s mining sector,” Mavunde stated during the launch. He emphasised that modern technology is the essential pillar of a national policy designed to maximise the sector’s contribution to the Treasury while maintaining global environmental standards.
Since the formation of the Twiga joint venture in 2019, Barrick has injected more than $4 billion into the Tanzanian economy, effectively ending years of previous friction between the state and the mining giant. Beyond large-scale corporate interests, the collaboration is providing a significant data windfall for the artisanal sector. Surveys that identify deposits unsuitable for industrial-scale mining are being handed over to the government to help formalise and empower small-scale miners, a strategy already proven successful in areas such as Majimoto and Golden Ridge.
Barrick’s Country Manager, Dr Melkiory Ngido, confirmed that the company has invested approximately TSh100 billion in scientific research over the past five years alone to secure the next generation of tier-one assets. The new helicopter survey represents the sharp end of this investment, offering a non-invasive method to probe the earth’s crust without the need for extensive road clearing or land disturbance. This commitment to “green” exploration is increasingly seen as a prerequisite for attracting the ESG-conscious institutional investment required for long-term mine development.
As global gold prices remain robust, the ability to rapidly convert geological data into operational mines will define Tanzania’s competitive edge in the African mining market. The integration of high-resolution aerial data into the national geological database not only serves Barrick’s immediate interests but also provides a permanent technical asset for the Ministry of Minerals. This synergy between private capital and public policy is intended to ensure that the current gold rush translates into sustainable economic development for future generations.
