- Edenville Energy's [LON:EDL] shares were up in late trading after it issued an update on its Rukwa coal to power project, in south-west Tanzania.

Edenville says work has started on the next stage of the power plant environmental and social impact assessmen. During Q3, Edenville, along with its consultant Tansheq, will be working to progress the necessary requirements needed to meet the standards of the Tanzanian National Environment Management Council. This includes areas such as consultation with relevant institutions, both governmental and commercial, along with stakeholder consultation and reviews focused on flora, fauna and socio-economic impacts.

This comprehensive work programme will then feed into the report requirements needed to complete the ESIA application process. Assuming other parts of the application process can be advanced in a timely manner, management expect the ESIA application process work to be completed in H1 2017. Work on the upgrading of existing access routes and the creation of new roads at the project site is largely complete.

Upgrade work on approximately 17km of roads in and around the project site has been completed, along with new access to the proposed site of the power plant.

Additionally, rejuvenation of local roads has taken place as part of the Company's Corporate Social Responsibility ("CSR") programme. Routine maintenance will continue as necessary and the improved access allows further pre development work to be accessed and completed more easily.

The recent site work further demonstrates the Company's continued commitment to moving forward with both the mining and power components of the project. Edenville says preparation work has been completed for bulk sampling at the Mkomolo deposit. Excavation is planned to take place at the start of August with a sample batch being transported to Johannesburg, South Africa, for treatment and analysis by SGS, a highly respected international laboratory company. The results will subsequently feed into design work for both the power plant combustion process and any associated coal treatment or washing facilities to service the proposed power plant. Edenville says that following several recent meetings in Tanzania, discussions on both equipment supply for the power plant and selection of suitable EPC groups for construction and operation of the project are reaching a more advanced stage. All the supply and EPC groups Edenville has engaged with have the capability to either directly or indirectly invest in the development of the project.

Edenville says: "Once Tanzania Electric Supply Company Ltd has defined its requirements for the projects key parameters more fully we would expect to move to a formal arrangement with one or more of these groups.

"Whilst the timing of this is outside the control of the Company, we will update the market as soon as more information is available. The Company is also continuing to review engineering options with Runh Power of China with whom we have a non-exclusive collaboration agreement."

KEFI Minerals' [LON:KEFI] board is being restructured as from August as part of the company's transition towards gold production.

It is intended that Mark Wellesley-Wood, experienced African mining operator, will join the board as non-executive director. He will also serve as chairman of the newly-created technical review committee and Professor Ian Plimer will serve as chairman of the newly-created exploration review committee.

The existing roles of deputy chairman and senior independent director will pass from Professor Plimer to Wellesley-Wood as from January 2017.

The board will establish its two new committees to independently review technical and exploration matters during the company's planned rapid expansion.

This will allow Jeff Rayner to step down from the board and to focus on a more free-ranging role to identify value adding opportunities for KEFI's next stage of development.

Rayner will also continue to advise and mentor the exploration team, which remains under group exploration manager, Dr Fabio Granitzio.

John Leach has agreed to join the senior executive team as finance director as this function expands in scale and responsibility.

KEFI says these changes to the structure of the board serve a number of important purposes as the company begins its transition towards production.

The board will comprise two executive directors (executive chairman Harry Anagnostaras-Adams and Finance Director John Leach) and three non-executive directors (His Excellency Norman Ling, Professor Ian Plimer and Mark Wellesley-Wood).

Executive management will continue to report to the executive chairman, notably the chief operating officer and managing director of KEFI Minerals Ethiopia, Wayne Nicoletto, the finance director John Leach and group exploration manager Dr Fabio Granitzio.

KEFI has already installed strong development, community, finance and exploration teams under these executives and will next assemble the production operations team. The principal project contractors are market leaders Ausdrill/African Mining Services and Lycopodium.

Anagnostaras-Adams said: "The planned changes to the Board of Directors announced today reflect our transition from exploration-only to emerging production as well as exploration. KEFI is fortunate to have such a depth of expertise from individuals adjusting their roles to suit the changing needs of the Company. We look forward to welcoming to the Board Mr Mark Wellesley-Wood, who has deep experience in African mining operations as well as mining finance in the City."
