Another year of mine site reclamation and sustainable farming
In 2023 we focused on scaling our reclamation programme and making our farming practices even more sustainable and productive. We continued to implement the recommendations of our agronomist advisor, which delivered increased yield, particularly for our rice crops. Using the System of Rice Intensification (SRI) method, where farmers plant fewer seedlings spaced further apart, farmers doubled rice yields during the harvest while using fewer resources.

Another focus was improving soil quality on our farms. We monitor the pH of the soil and reduce its acidity by adding oyster shells or compost. After so many years of mining, some of the soil was so degraded that enriching it would not be sufficient enough. Instead, we removed the most degraded soil and added entirely new topsoil and compost, which has significantly improved crop growth.
Tongoro 11 & 12 – trenching system and reclamation
This year we piloted the trenching method with two GemFair member sites based in the Southeast of Koidu and share common boundary. Both sites were selected for FPA 2022/23 and completed the mining work in July 2023. At both sites the miners extracted gravel and backfilled each trench as they continued.
Two trenches remained at the end of the mining phase in both license areas. Under the trenching method the pits were backfilled with tailings from washed gravel and then the entire mined area was covered with the topsoil retained at the start of mining plus new topsoil made from composting. The reclamation work was completed by the same miners who had mined the site with support from GemFair including purchasing the tools needed for the work.
New topsoil was made with support from GemFair staff. The diggers were able to prepare compost which was ready for use by the time they had finished backfilling and levelling the mined areas. The license holder appreciated learning how to do this very much, as well as having the opportunity to get his land back to a useful state as before the mining.
Next, the license holder planted rice, banana and orange trees which can provide future harvests.
The trench method is faster and less expensive than traditional methods of reclamation in artisanal mining. The reclamation work is efficient because most of the pits had been covered during mining ensuring the entire site is returned to its original state earlier.

Deep dive: Transforming a former diamond mine into a fish pond
What do you do with a former mine site that was excavated using heavy equipment, making it nearly impossible to reclaim with our model of employing local workers? That’s a question we tried to answer in late 2022. During this time, we worked with the community in Tefeya village to find such a site that was abandoned where we could pilot a new use for the pit: converting the pit to a pond and populating with native fish.
A local team of ten workers led by a local fishpond expert constructed the pond over a three-week period. Then we treated the pond with lime to regulate the water’s Ph level so that it would be hospitable for the tilapia fingerlings (a term for young tilapia). After some months of allowing algae to grow, we worked with the fishpond expert to source and stock the pond with 700 fingerlings and provided a lesson to GemFair staff and the community on how to feed the fish.
Our journey to date has been a huge success – we have recorded nearly 1,500 fish, including fingerlings, juveniles and adults.
For the villages surrounding this pond, it’s providing an affordable source of food and income from selling the fish at the market.

Access to Finance programme expands
We further expanded our Forward Purchase Agreement (“access to finance”) programme in 2023, in recognition of the pressing need in the artisanal mining sector for fair, equitable and transparent finance. This carefully designed programme delivered vital capital to 56 mines sites, allowing them to hire labour on fair terms and cover operational costs including equipment and consumables. In addition to finance, all of our sites receive a stipend to cover daily meals for miners, ensuring a happy and healthy workforce.
We also took two important steps to ensure the long-term financial sustainability of the FPA programme. Firstly, we redoubled efforts to base financing decisions on our increasing knowledge of the geological potential of mine sites; this allowed miners to conduct activity with greater confidence of unearthing valuable diamonds and deriving enhanced incomes from the activity.
Secondly, we redefined our repayment terms, in consultation with the miners to ensure a more equal spread of diamond value across accruing across all FPA recipients. As in previous years, if miners are unable to repay through diamond winnings within the season, the risk is assumed by GemFair and no debt is carried forward.
The desire to continuously improve provision for miners drives decisions across our programme. As such, in advance of the season we held a workshop with mine managers and licence holders to ask them how we could improve our offering. Whilst the feedback was overwhelmingly positive, a number of valuable insights were directly translated into updated programme benefits. These include:
- All miner incomes were benchmarked against our living wage calculation and updated to account for forex changes and inflation.
- All operational licence holders were considered part of the workforce and therefore able to access daily remuneration, in addition to diamond winnings.
- The stipend for health care provision was increased.
- Surface and Development rights and Licence fees covered for all FPA beneficiaries.
