Case Study: Geita Gold Mining Limited – A Model of Success in Tanzania’s Mining Industry

Introduction to Geita Gold Mining Limited (GGML)

Geita Gold Mining Limited (GGML), situated in North-Western Tanzania within the Lake Victoria goldfields of the Geita region, stands as one of the flagship mining operations of AngloGold Ashanti. The Geita mine, with a rich history spanning several decades, has evolved into one of Tanzania’s largest and most significant gold mining projects. Located approximately 120 km from Mwanza City and 4 km west of the township of Geita, the mine has contributed significantly to both Tanzania’s economic growth and AngloGold Ashanti's portfolio.

Operating since the early 2000s as a large-scale mining operation, GGML traces its origins back to the 1930s, when early gold exploration and mining activities were initiated in the region. Today, it is a major producer of gold, extracting minerals through both open-pit and underground mining methods.

This case study will delve into the history, operations, development, and sustainability efforts of Geita Gold Mine, while highlighting the key elements that have contributed to its success and longevity. The study will also examine the challenges the mine has faced, its financial performance, its contributions to Tanzania’s economy, and its future prospects.

The Formation and Development of Geita Gold Mine

Early Beginnings and Historical Background

Geita Gold Mine’s journey began in 1936 when the first gold deposits were discovered in the Geita region. By 1966, three small-scale mines in the area had produced nearly 1 million ounces of gold. Despite early success, mining operations were relatively limited during the early years, and only modest amounts of gold were extracted from the region.

In the 1990s, as part of Tanzania's effort to encourage foreign investment in the mining sector, Ashanti Goldfields (now part of AngloGold Ashanti) acquired the Geita project in 1996 through the acquisition of Cluff Resources. A significant turning point for the mine came in December 2000, when Ashanti sold a 50% interest in the Geita project to AngloGold for $324 million. This partnership set the stage for the modernization and expansion of mining operations at Geita, ultimately establishing the mine as a significant player in the gold industry.

The 2004 AngloGold Ashanti Merger

In 2004, the merger of AngloGold and Ashanti resulted in the operation being fully managed and operated by AngloGold Ashanti. This merger brought about a focused strategy for the development of the Geita mine, which included investments in modern mining techniques, increased production capacity, and extensive exploration to unlock more resources.

Over the years, AngloGold Ashanti has committed significant resources toward the modernization of the Geita mine, transitioning from traditional open-pit mining operations to a more sophisticated mix of open-pit and underground mining methods.

Transition to Underground Mining

In 2015, a critical decision was made to expand operations underground, particularly at the Star and Comet deposits. This decision was driven by the need to access deeper gold resources that were not viable through open-pit mining methods. The underground development officially began in 2016, marking the beginning of a new phase of expansion for the mine.

In 2017, the Nyankanga underground operation was also initiated. These expansions reflect the mine’s commitment to long-term growth and the pursuit of sustainable resource extraction.

Current Mining Operations

Geita’s Mining Methodology

As of 2020, the Geita Gold Mine operates using a combination of open-pit and underground mining. The mine is divided into multiple sections, with key areas such as Nyankanga, Geita Hill, and Star & Comet being the primary focus of mining operations.

• Open-Pit Mining: The open-pit operations at Nyankanga and Geita Hill continued into 2020, although the economic life of the Geita Hill pit reached its end in 2020. Mining at the Nyankanga pit was completed in September 2020, after which the mine shifted its focus to Nyamulilima.
• Underground Mining: The underground operations at Star & Comet and Nyankanga are designed to extract gold from deeper veins that cannot be reached using open-pit methods. The underground mining development was supported by 1,555 meters of capital development, which allowed access to new areas for stope mining.
• In April 2021, Geita Gold Mining commenced open-pit mining at Nyamulilima, which is located 2.4 kilometers from the Star & Comet deposits. With expected gold production of one million ounces over the next six years, Nyamulilima has become a key area of focus for the operation.

Power Supply and Energy Efficiency

Geita Gold Mining is powered by a 40MW power plant, comprising four diesel generators. This plant, commissioned in August 2018, ensures that the mining operations receive a reliable power supply. In 2020, the Tanzania Electricity Supply Company (TANESCO) initiated plans to connect the mine to the national grid, with an expected connection in 2021. The mine is being linked to a 220/33kV power line located six kilometers away at Mpomvu village, with a 33/11kV 60MVA substation currently under construction.

The planned connection to the national grid is expected to improve the mine’s power supply reliability while reducing reliance on diesel, leading to cost savings and a smaller environmental footprint.
