Savannah’s CEO, David Archer said: “Whilst we await the outcome of Government analysis, we continue to make progress in advancing some critical work streams at Mutamba. A sequenced scheduling of PFS activities has been agreed and key initial studies are either underway or about to start. These include hydrology studies, port options and the collection of 10 tonnes of sample material to aid in final product determination. These are all essential elements that will inform the PFS and the results of which will guide us in the infrastructure, power, mine planning and process plant requirements. It is an exciting time as we see the future mine plan form and take shape.”
Savannah Resources plc (LON: SAV and SWB:SAV), a resource development company, is pleased to provide the following update on the Mutamba Heavy Minerals Sands Project in Mozambique which is being developed by a consortium with Rio Tinto.

-- The three mining lease applications, covering a total area of 417.32km(2) for the Jangamo, Dongane, Ravene and
Chilubane deposits, are currently being actively considered by the Mozambican mines department;
-- Activity continues on several fronts in the lead up to the anticipated grant of mining leases
-- Following extensive testing the pilot plant has been placed under care and maintenance, as planned, whilst a bulk
sample is obtained;
-- Community development activities required as part of the licencing process continue; an
-- The scoping phase of the Pre-Feasibility Study ('PFS') is now well advanced and the initial key studies for the
PFS have been sequenced, with roll out underway, including further roasting test work and a 10t bulk sample to be
collected from the Matilda licence.
Mining Lease Applications
The applications were submitted earlier this year in the name of Mutamba Mineral Sands S.A., a wholly owned subsidiary of Rio Tinto Limited and cover a total area of 417.32km(2).
The applications, which are currently being reviewed, were submitted to the Ministry on 18 January 2018 and the mining cadastre reopened on 2 April 2018 following its annual closure. The Ministry has six months from the date of the cadastre reopening to respond to the Applications, although this can be an iterative process. Mining Leases are generally awarded for a term of 25 years and can be renewed at the end of their terms.
Savannah is the operator of the Mutamba Project with an existing 20% interest in a Consortium Agreement with Rio Tinto. Savannah can increase its equity to 35% upon delivery of a Pre-Feasibility Study which is currently underway and to 51% upon delivery of a Definitive Feasibility Study.
Pilot Plant
The pilot plant was inaugurated on 7 December 2017. Since then the plant has been run on a steady basis to ensure it is operating properly and has now been placed on care and maintenance, as planned, while a bulk sample is obtained for processing.
Community Development Activities
Support for local community development initiatives is both a mandatory part of the licence process and an essential part of Savannah’s active community engagement programme with a view to further building on the good relationships and trust the Consortium has with the local authorities and local communities.
To date the Consortium has provided:
-- 508 double school desks (Figure 1 - See PDF) to schools in the local districts;
— over 7,000 seedlings for improved and disease resistant coconut plants, as well as, support to cassava production and appropriate trade skills development;
-- basic equipment and consumables to local health clinics; and
— ongoing village water supply systems (Figure 2 – See PDF) to five of the neediest settlements, which is estimated to benefit up to 7,500 people in the provision of clean, potable water

Pre-Feasibility Study
A Pre-Feasibility Study (‘PFS’), being managed by mineral sands expert TZMI, into the potential development of the project began in latter part of 2017. It is targeted for completion in early 2019 and will be a major milestone for the Company as it will further define the commercial potential of Mutamba whilst also resulting in Savannah earning a 35% interest in the Mutamba Consortium. Stage one of the Mutamba PFS is well advanced and includes a gap analysis, options review, project planning and budget finalisation for stage two of the PFS.
Significant planning by TZMI has been undertaken over the recent months as the Consortium prepares to enter into stage 2 of the PFS and a sequenced approach to the PFS has been developed that will ensure that reports and studies build on each other as the PFS unfolds. The first of these studies have been identified and preparations underway for their roll out.
The first set of studies include:
-- Mining methods analysis and strategic scheduling; -- Tailings design and storage options;
— Metallurgical test work programme, the results of which will help inform the engineering design;
-- Port options study; and -- Hydrology study to update, calibrate and validate the existing models.
Once complete, these studies will inform and lead the remaining work required to complete the PFS.
