Barrick Gold Corporation announced Tuesday a $500 million investment in its Geita Gold Mine, Tanzania's largest gold producer, signaling renewed confidence in the country's mining sector following years of regulatory reform.

The expansion, which will extend the mine's operational life through at least 2040, includes construction of a new processing plant, development of underground mining infrastructure, and exploration of deeper ore bodies that geological surveys indicate could contain an additional 3.5 million ounces of gold reserves.

A Strategic Bet on Tanzania

"Tanzania has demonstrated its commitment to creating a stable, predictable environment for mining investment," said Mark Bristow, Barrick's President and CEO, in a statement. "This expansion reflects our confidence in the country's future and our partnership with the government."

The announcement comes three years after Tanzania overhauled its mining legislation, introducing a new framework that increased state participation while providing greater certainty for international investors. The reforms, initially controversial, have since been credited with attracting renewed investment to the sector.

"This is exactly the kind of investment Tanzania needs. It creates jobs, transfers technology, and builds the foundation for a sustainable mining industry that benefits all Tanzanians."

What the Expansion Includes

The $500 million investment will be deployed over five years and includes:

• New processing facilities with 50% higher throughput capacity
• Underground development accessing ore bodies below 800 meters
• Exploration program targeting extensions to known deposits
• Community infrastructure including schools, health facilities, and water systems
• Environmental systems including a new tailings management facility meeting international standards

Economic Impact

The expansion is expected to create 1,200 new jobs during construction and 400 permanent positions once operational. Local content requirements will ensure Tanzanian suppliers benefit significantly from procurement, with the company committing to source at least 60% of goods and services domestically.

Geita currently produces approximately 500,000 ounces of gold annually, making it one of Africa's top ten gold mines. The expansion could increase output to 650,000 ounces per year at peak production.

Industry Response

The announcement has been welcomed by industry observers as a sign that Tanzania's mining reforms are achieving their intended effect.

"Three years ago, there was real uncertainty about the future of mining investment in Tanzania," said James Morton, Africa mining analyst at Standard Bank. "This expansion shows that international majors are prepared to commit capital for the long term when the policy environment is right."

Other major miners operating in Tanzania, including AngloGold Ashanti and Shanta Gold, have also announced expansion plans in recent months, suggesting a broader recovery in sector investment.

What This Means

For Tanzania, the Geita expansion reinforces the country's position as one of Africa's most important mining jurisdictions. Gold remains the country's largest export, accounting for approximately 40% of total export earnings, and the sector provides direct employment to over 15,000 workers at large-scale operations.

The investment also demonstrates the potential for constructive partnerships between international mining companies and host governments, a model that Tanzania is actively promoting to other African nations.
