The gold mining sector is witnessing significant expansion in 2025, with several major projects entering production during the first half of the year. These developments represent critical new gold flows from new mines into the global market, with both greenfield and brownfield projects contributing to production growth. Four notable operations have commenced gold production, adding approximately 724,000 ounces of annual gold capacity to the global supply chain at peak production.
These new gold mines span across three countries – Canada, Burkina Faso, and Australia – representing a diverse geographic distribution of new production centers. The timing of these developments is particularly significant given the strong gold market performance that has encouraged capital deployment into both new projects and revitalization of previously operating sites.
What Are the Latest Gold Mine Developments Entering Production?
The gold mining industry has seen a balance of both greenfield and brownfield projects coming online in 2025, each presenting unique development characteristics and production profiles. These mines represent significant capital investments across different jurisdictions and mining environments.
Major Greenfields Projects Coming Online
Two major greenfield projects have marked their inaugural gold pours in mid-2025, representing substantial investments in new mining infrastructure and processing facilities:
B2Gold's Goose Mine (Nunavut, Canada)
- First gold pour achieved in June 2025
- Represents B2Gold's first Canadian production asset
- Acquired through C$1.1 billion takeover of Sabina Gold & Silver Corp
- Significant development in the remote Canadian Arctic region
West African Resources' Kiaka Project (Burkina Faso)
- First gold pour achieved in July 2025 (5.7kg gold bars in initial smelt)
- Delivered ahead of schedule and under budget at US$447 million
- Will operate alongside West African's existing Sanbrado operation
- Establishes the company as a major West African gold producer
These greenfield developments are particularly significant as they represent entirely new sources of gold production rather than extensions or revivals of existing operations. Each project required extensive infrastructure development, environmental permitting, and construction of processing facilities in relatively undeveloped areas.
"The commencement of gold production at the Goose mine marks an exciting step in B2Gold's history, further diversifying and adding to the quality of the company's existing global operating portfolio," said Clive Johnson, B2Gold CEO.
Brownfields Revivals Contributing to Production
In contrast to greenfield developments, brownfield projects leverage existing infrastructure and previously developed mining areas, often resulting in more rapid development timelines and lower capital requirements:
Meeka Metals' Murchison Gold Project (Australia)
- Andy Well processing plant restart at A$46 million investment
- Utilizes existing infrastructure with targeted upgrades
- Expected to achieve production more rapidly than equivalent greenfield project
Native Mineral Resources' Blackjack Mine (Australia)
