In a move that injects fresh air into the often-murky world of resource extraction, Gemfields, a leading mining company, is pioneering transparency with its unique “G Factor for Natural Resources” initiative.

First announced in July 2021, the G Factor serves as a beacon of accountability, shedding light on the level of natural resource wealth shared with governments. As reported by Mining Weekly on April 24th, Gemfields has not only released updated figures for 2023 but also issued a clarion call to industry peers and governments to embrace this groundbreaking measure.

The G Factor operates with refreshing simplicity. It calculates the percentage of a mining company’s revenue that finds its way back to the government through primary and direct taxes. This, according to Gemfields, also reflects the company’s efficiency in converting resources into financial gain for the host nation.

The results for Gemfields’ two key subsidiaries paint a heartening picture. The Montepuez ruby mine in Mozambique demonstrably contributed a noteworthy 35% of its revenue to the state coffers in 2023. Similarly, the Kagem emerald mine in Zambia delivered a significant 31% share.


This commitment to transparency extends beyond mere figures. While Gemfields itself reported a profit of $151.3 million (9.5 billion meticais) for the year, Zambia’s coffers swelled by $92.7 million (5.8 billion meticais) – a testament to the shared prosperity that responsible resource management can foster.

“The G Factor offers a clear and concise metric for stakeholders to assess how effectively extractive companies translate resources into wealth for the nations they operate in,” explains Sean Gilbertson, CEO of Gemfields. This innovative approach aligns with the company’s desire for greater regional alignment, with plans to incorporate export duties and fees into future calculations.

Gemfields’ vision extends beyond self-promotion. The company aspires to see the G Factor become the industry standard, a call to action echoed in Gilbertson’s concluding remarks: “We hope to see the voluntary adoption of the G Factor by other companies and governments, potentially integrating it with initiatives like the Extractive Industries Transparency Initiative (EITI).”

By championing transparency, Gemfields sets a new precedent for the mining industry, paving the way for a future where resource wealth benefits not just corporations, but also the communities that hold the riches beneath their soil.
