The world’s single-largest producing emerald mine. The 41 square kilometre licence area is located in the Ndola Rural Emerald Restricted Area and lies south of Kitwe and west of Ndola, in Zambia’s Copperbelt Province. It is 75% owned by Gemfields and 25% owned by the Government of the Republic of Zambia. The mine comprises three open pits.

Kagem produced 80,900 carats of premium emerald for the six months to 30 June 2019.
Kagem’s commercial-quality auction in August 2019 achieved revenues of US$22.4 million, with an average price per carat of US$71.85.
In 2007, Gemfields Group Limited (formerly Pallinghurst Resources Limited) (“GGL”) identified the coloured gemstone sector as an “overlooked” industry that offered a unique investment opportunity. Demand for coloured gemstones by the jewellery and fashion sectors was increasing, but supply was constrained and fragmented due to the lack of large, reliable producers able to consistently deliver sufficient quantities of gemstones. Pallinghurst saw an opportunity to unlock value by bringing capital, scale and professionalism to the industry, to which end it assembled a consortium of Pallinghurst Co-Investors, including the Group.
Kagem, an emerald mine in the “Copperbelt” region of northern Zambia, currently producing nearly a quarter of the world’s emeralds, was the consortium’s first acquisition in the sector. Kagem had been producing emeralds for nearly 20 years but was performing badly due to a combination of poor management, theft, shareholder conflicts and a lack of capital. Through a series of transactions, the consortium acquired 75% of Kagem, with the balance held by the Government of the Republic of Zambia. In pursuing its vision for consolidating the sector, the consortium acquired majority control of AIM-listed Gemfields plc (“Gemfields”) by selling Kagem to Gemfields in a reverse takeover during 2008.
The Mbuva-Chibolele licence is located on the Fwaya-Fwaya–Pirala Belt in the NRERA within the Kafubu area of the Copperbelt Province of Zambia, on the southern banks of the Kafubu River. It lies along the west-southwest strike from the nearby Fwaya-Fwaya emerald mining zone adjacent to the Kagem licence area. This pit was kept under care and maintenance from 2007 onwards so as to focus on operations at Kagem. However, following GGL’s acquisition of Gemfields, a decision was made to expand the Group’s emerald footprint and, accordingly, operations at Mbuva- Chibolele were resumed in late 2017.
Gemfields implemented an innovative grading and auction system for selling its rough gemstones. The auctions are held in secure locations with the material separated into homogenous lots and certified as either having been produced by Gemfields or obtained by Gemfields from third parties. The world’s leading rough gemstone buyers submit sealed bids for individual lots. A sale occurs if the highest bid received exceeds a pre-determined, but undisclosed, reserve price. The auctions have brought a level of professionalism and transparency previously not seen in the industry.
As there was no industry standard for evaluating rough coloured gemstones, Gemfields established its own grading system to assess each gem according to its individual characteristics (size, colour, shape and clarity). This approach has been instrumental in providing buyers with confidence in the consistent quality of the material on offer. Gemfields used this grading system to develop two auction classes, one offering higher quality gemstones and the other for the larger volume of lower quality gems.
Since its first auction in July 2009, Gemfields has seen increased demand for its responsibly sourced and transparently supplied emeralds, highlighting the success of its formalised and consistent method of marketing rough coloured gemstones by auction.
Gemfields’ 33 auctions of emerald and beryl mined at Kagem since July 2009 have generated US$608 million in aggregate revenues. Gemfields continues to experience significant demand for its responsibly sourced emerald and beryl with successive auctions regularly achieving record per carat prices and auction proceeds.
During the year, Kagem continued the removal of overburden in three sectors of the Chama pit (F10, Chama and FF-Mboyonga), effectively clearing the way to the emerald formation for mining. In addition, certain sections of the pit were further cleared and de-ramped, allowing a consistent production profile at Chama. The efficiencies achieved from redesigning the pit have continued, with a larger, more efficient fleet being deployed in the pit. Fibolele continued to provide additional sources of production, and the extension of the strike length by 600 metres during the year exposed more emerald- and beryl-yielding contacts.
Gemstone production for the year was 35.5 million carats of emerald and beryl, with 224,000 carats of premium emerald, an increase in premium production of more than 493% over the entire 12 months to June 2017. Of the total production, the Chama pit contributed 31.5 million carats and the bulk sampling projects in Fibolele and Libwente contributed 4 million carats. The variability of emerald production at Kagem is primarily due to the geological factors influencing initial formation millions of years ago.
The implementation of high-resolution digital surveillance CCTV (comprising 20 mobile CCTV cameras and eight PTZ cameras with recording capability) and radio communication continued to aid effective and efficient management of the security systems, with permanent patrol teams being stationed in and around all the dump sites to provide robust protection and surveillance in respect of the mining licence area. The sort house security system was further enhanced with the construction of an electrical fence.
Kagem continues to pride itself on, and endeavours to maintain, its ability to conduct mining in a responsible, transparent and safe manner with minimal impact on the natural environment. Kagem aims for a zero-harm (injury-free) culture where health and safety are not only considered critical to the operation, but are also ultimately the responsibility of each individual employee. Training of employees in various safe work practices continued to be rolled out during the year.
CSR and employee welfare were a key focus during the period and several committees were formed to improve overall life outside the work areas. Kagem’s CSD strategy sets out planned projects with the agreement of local stakeholders. Kagem’s sustainability department develops and implements its CSD strategy directly in line with the Group’s sustainability strategy to support health, education and agricultural projects in the two areas ruled by local chiefs.
With this transformation into an operating company, the Kagem and Montepuez mines become the foundation upon which we intend to build the future of the Company.
Through its successful auction system, Gemfields has cemented its position as the world’s leading supplier of both rubies and emeralds.
Gemfields is honoured to announce the discovery of ‘Inkalamu’, the Lion Emerald, a 5,655 carat Zambian emerald crystal with remarkable clarity and a perfectly balanced golden green hue.

The global coloured gemstone market continues to grow soundly and Gemfields has the potential to expand through its existing emerald and ruby businesses, its recently acquired projects and to apply its successful model to other coloured gemstones.
