Africa-Press – Mozambique. <\/strong> <\/span>Gemfields reported long-term G-Factors of 17% at Kagem and 26% at Montepuez, underscoring substantial revenue sharing with host governments.<\/b>
\nThe miner\u2019s 2025 data show a strong 23% G-Factor at Montepuez but a temporary drop to 6% at Kagem, reflecting operational disruptions and market headwinds.<\/b><\/p>\n

Gemfields has updated its \u201cG-Factor for Natural Resources\u201d metrics to the end of 2025 for its key operations, showing long-term government-take ratios of 17% at Zambia\u2019s Kagem emerald mine and 26% at Mozambique\u2019s Montepuez Ruby Mining.<\/p>\n

The G-Factor expresses the share of a mine\u2019s revenue paid to host governments via royalties, corporation tax, dividends and export levies, and is intended as a transparency tool for natural resource revenues.<\/b><\/p>\n

At Montepuez,<\/b> the one-year G-Factor for 2025 was 23%<\/b>, with US$11.3 million<\/b> paid to the Mozambican government on revenue of US$49.9 million, a strong proportional contribution despite lower cash payments due to weaker premium-ruby output, a delayed auction and illegal mining disruptions.<\/p>\n

At Kagem<\/b>, the 2025 G-Factor fell sharply to 6%, reflecting a four-month shutdown and a temporary 15% export tax that compounded poor market conditions, although Gemfields expects the mine\u2019s fiscal contribution to revert toward its roughly 18% long-term average as operations normalise.<\/p>\n

By continuing to publish the G-Factor annually for its subsidiaries, Gemfields is positioning itself as a proponent of fiscal transparency in the mining sector and urging broader adoption across extractive industries. The metric offers host governments and citizens a simple indicator of how efficiently their natural resources are converted into public revenues, even while the company acknowledges its limitations and the exclusion of various indirect taxes from the calculation.<\/p>\n
