CEO Statement

Following Rainbow’s IPO at the beginning of 2017, the six months to 31 December 2017 was a busy and highly productive period for Rainbow, during which we commenced production of rare earth concentrate from one of the highest grade projects globally on schedule and on budget.

During the period, the initial mine at Gasagwe developed from an area which had undergone manual pre-stripping work only, to an operational mine site. At the same time, the plant site at Kabezi went from being an area which had been cleared and levelled, to the site of an operating plant which had, by the end of 2017, completed the first two exportations of mineral concentrate.

Rare earth prices also strengthened over the period, buoyed by growing demand from green technologies such as hybrid and electric vehicles. As owners of Africa’s only producing rare earth mine, and one of only a few outside China, the Company is well placed to take advantage of the burgeoning rare earth market.

Although the focus was on constructing the plant and commencing production during 2017, ground gravity and airborne radiometric surveys undertaken during the period identified some highly prospective, and large, anomalies within Rainbow’s licence area.

In December, the Company successfully completed a share placing which raised net proceeds of US$3.5 million in order to finance an exploration programme to investigate these exciting anomalies, as well as to accelerate production growth through expanding the mining fleet.

Gakara mine – from development to production

The first six months of 2017 were focussed on assembling the teams and sourcing the equipment and suppliers needed to bring the mine into production by the target date for first shipment in Q4 2017 and we were delighted that, thanks to the hard work by our team on the ground at Gakara, we were able to achieve this goal on schedule.

At Gasagwe, the project’s first mining area, manual site preparation work had commenced in April following the recruitment of a team of local workers. Waste stripping continued for the rest of the year, exposing the main vein of ore as well as additional subsidiary veins in the process.

By the end of June 2017, site clearance and initial preparation work had also begun at the plant site at Kabezi, 13km south of Bujumbura.

On 21 July 2017, the mine was pleased to host His Excellency President Pierre Nkurunziza, who conducted an inauguration ceremony followed by traditional celebrations at the nearby town of Mutambu. The ceremony was very well attended and included a speech by Burundi’s Minister for Mines and Energy, Come Manirakiza, echoing the support that Rainbow has received from the Government of Burundi and the local population.

Between July and December 2017, construction of the processing plant at Kabezi was in full swing. Bulk earthworks were completed by July, followed by civils between August and November. Pre-assembled plant parts began to arrive in containers in August, and construction of the plant itself took place between September and December. Commissioning of the plant began on 5 December 2017, and the first shipment of 25 tonnes of rare earth concentrate was also announced on that date. By 31 December 2017, a second 25 tonne shipment had been completed, and a further 25 tonnes of production had been bagged at the plant site. The first two shipments were then sold together as a batch of 50 tonnes to thyssenkrupp Raw Materials (‘TK’) in January 2018, with title transferring at the port of Mombasa in Kenya.

Some 270 tonnes of material had been manually mined by the end of December following the commencement of mining of ore in earnest in September. Commissioning is now complete and final handover of the plant later in February 2018 will allow the rate of ore mining to increase considerably, as the separation of waste from ore will be handled by the plant itself.

Safety, health and community

During December 2017, the milestone of 500,000 man hours without a Lost Time Injury (‘LTI’) was passed. The Company is rightly proud of this achievement, and places great importance on the attention paid to safety practices at all levels of the organisation.

The Gakara project is the only non-artisanal producing mine currently operating in Burundi. As such, it is extremely important not only to local communities, but also to the nation of Burundi as a whole. We are therefore delighted that as at period-end, Rainbow’s local operating entity employed 177 workers, and a further 208 as subcontractors, in an area of high unemployment.

In addition, the taxes and royalties generated by the mine will boost the government treasury, while exports will bring much-needed foreign currency into the country, much of which is spent with local suppliers.


With the focus on mining operations and construction at Kabezi, exploration activity was limited during the six months to 31 December 2017. However, the work undertaken yielded some exciting results.

Stream sampling and geo-traversing mapping continued throughout the year, and by 31 December 2017, 69 new rare earth element (‘REE’) occurrences had been found across the licence area. A total of 1,168 REE occurrences have now been found at Gakara to date.

A ground gravity survey was conducted at Kiyenzi, one of the prospects where high grade bastnaesite/monazite boulders had been found on the slope of the hill, to try to locate the source of the REE material. The survey yielded a dense, sill-type anomaly with an elliptical shape of 80m x 100m in size and potentially 20m thick.

Furthermore, an airborne magnetic survey flown in October 2017 over the entire Gakara licence area indicated the presence of four sizeable and highly prospective magnetic anomalies, the largest of which covered an area which includes the Gashirwe and Kiyenzi prospects. These targets, which are conjectured to be related to large intrusions at depth, possibly representing the magmatic sources of the Gakara REE vein system, appear to be structurally controlled and vary in size from 300m to 2,700m in diameter

As previously announced, a drill programme for Q1-Q2 2018 is currently underway which will initially target these prospects.


In December 2017, the Company successfully completed an over-subscribed share placing for 20 million shares at 14 pence a share (a 40% premium to the IPO price). The net proceeds of US$3.5 million will be used to finance the drilling programme mentioned above, in addition to the expansion of the mining fleet in order to bring forward and increase production growth, while also shoring up the Group’s balance sheet.

Rare earths market

After two years of inactivity, rare earth prices increased considerably in the second half of 2017. The basket price of Rare Earth Oxides (‘REOs’) based on Gasagwe’s estimated composition, which had ranged between US$10-11 per kg TREO during the first six months of 2017, reached a peak in excess of US$18 per kg in September, before ending the year at US$12.27 per kg and strengthening further to US$13.24 per kg as at 20 February 2018.

Over 80% of Rainbow’s basket price is made up by Neodymium (Nd) and Praseodymium (Pr), the so-called ‘magnet rare earths’ due to their application in the manufacture of the strongest permanent magnets. The fundamentals for NdPr remain strong over the long term, with production being restricted due to a clampdown in China on illegal and environmentally damaging mines, together with a growth in demand coming from green technologies, such as electric vehicles and wind turbines.

The Gakara mine is one of the world’s few rare earth mines in production outside China. Many of the rare earth projects currently in development require significant funding in order to be built, and in many cases rely on long term rare earth prices higher than current levels in order to be economically viable. It is therefore considered unlikely that further increases in rare earth prices will lead to an increase in market supply for a number of years.

During 2017, the Chinese government announced measures to reduce pollution from its rare earth mines, as well as to tackle illegal mining. In addition, according to Argus Media, Chinese authorities set an overall target to reduce total rare earth output to 140,000t REOs by 2020-21, a drop of around 20-25% from current production levels. As approximately 85% of global rare earths production comes from China, this represents a significant reduction, which is unlikely to be met by increased output from non-Chinese sources, and is therefore likely to drive rare earth prices upwards, particularly those such as NdPr for which demand is growing over the same period.


Rainbow has two priorities over the coming six months: to ramp up production at Gakara as quickly as possible; and to complete the first phase of a drilling programme designed to understand the anomalies identified in 2017.

Commissioning of the plant continued into 2018, with modification work undertaken on the jig and shaking tables to cater for a range of differences in ore feed. Some delays were experienced particularly in respect of the importation of certain parts and services necessary to complete required adjustments, which pushed the final completion of commissioning into early February, but the plant is now successfully running as designed.

Exports of concentrates increased from 50 tonnes in December 2017 to 75 tonnes in January 2018, and February’s export figure is due to be higher still. These levels will ramp-up quickly over the coming months following completion of plant commissioning, and the increased rate of mining.

The second half of 2018 will be focussed on reaching the stated run-rate production target of 5,000 tpa by the end of the calendar year.

If the initial results of drilling, which are anticipated in April 2018, are successful, the Company expects to progress to a second phase drilling campaign, and to announce a maiden JORC resource during H2 2018.

Financial Review


As the Gakara mine had only begun production at the end of the six months ended 31 December 2017, the Group’s financial results largely reflect the capitalised costs of mine construction and development, as well as its financing activities (notably the equity placing in December).

Income statement

No revenue was recognised in the period as although two shipments of concentrate were completed prior to 31 December 2017, the transfer of title (the point at which the risks and rewards of ownership are deemed to transfer to the buyer, TK), did not take place until January 2018. In addition, the Company will continue to capitalise both sales and mining expenses until commercial production has been achieved, which is expected to be some time during Q2 2018.

Operating expenses included US$0.6 million of administration costs (six months to 31 December 2016: US$0.2 million). These included corporate costs, support staff salaries, Directors’ remuneration, professional and advisors’ fees, and other office and administrative functions, which were not capitalised in the period. Direct costs of construction and mining operations were capitalised as mining development costs, without any allocation of overheads.

The increase compared with the equivalent period to 31 December 2016 reflected the increased activity associated with the construction of the Gakara mine – activity during the months prior to the IPO in January 2017 had, by comparison, been deliberately low level.

Share based payment costs of US$0.5 million (31 December 2016: US$ nil) related to share options which were awarded during 2017, including 2.5 million options awarded to Board members on 23 August 2017 at an exercise price of 15 pence per share (a 35% premium to the market price at the date of award).

Finance costs were less than US$10k during the period, compared with US$0.3 million for the six months to 31 December 2016, and related primarily to interest on the Finbank overdraft drawn in the period. In the comparative period to 31 December 2016, the Company incurred interest and other finance costs associated with the US$1.5 million Pala loan and the US$0.25 million loan from Alpha Future Investments Limited (both of which were settled in January 2017).

The Total Loss after Tax and Comprehensive Expense of US$1.1 million (31 December 2016: loss of US$0.4 million) primarily reflects the total of administrative expenses incurred during the period plus finance costs.

Balance sheet

The Company’s fixed assets increased to US$8.7 million by 31 December 2017 (30 June 2017: US$6.0 million). This related to the capitalised construction and exploration costs, together with plant, equipment, and vehicles acquired in respect of the Gakara project.

The increase in the period reflected the activity in the six months to 31 December 2017, during which the Kabezi plant was acquired and assembled, the plant and mining sites pre-stripped and prepared, and mining operations commenced.

As a result of these mining activities, approximately 270 tonnes of unprocessed run of mine (‘RoM’) ore and unsold concentrate was produced by 31 December 2017, which has been included on the balance sheet at its cost of US$0.4 million.

At 31 December 2017, outstanding subscriptions from the equity placement in December 2017 amounted to US$0.3 million, recorded under other receivables. These amounts were received in early January 2018.

Trade and other payables of US$0.4 million (30 June 2017: US$0.4 million) related primarily to trade creditors and accrued expenses in respect of the Company’s operations in Burundi.

Short-term borrowings as at 31 December 2017 were US$0.3 million (30 June 2017: US$20k), which consisted primarily of the Company’s Burundian Franc (BIF) overdraft with Finbank Limited.

Cash flow statement

At 31 December 2017, the Group’s cash position was US$2.7 million, or US$2.4 million net of borrowings. This represented a net cash outflow of US$0.5 million compared with the opening cash balance of US$3.2 million at 30 June 2017 (six months to 31 December 2016: net cash outflow of US$0.1 million).

Cash expenditure in the period related primarily to operating costs and capex in respect of the Gakara project.

Net cash outflow from operating activities of US$1.1 million (six months to 31 December 2016: US$0.1 million) primarily reflected the US$0.6 million of administrative expenses and US$0.4 million capitalised mining costs related to the ore stockpiles.

US$2.8 million of net cash used in investing activities related to the cost of constructing the Gakara mine, in particular the civils and earthworks at Kabezi and Gasagwe (such access roads, groundworks, and concrete foundations), and the cost of importing and assembling the processing plant. Activity during the six months to 31 December 2016 predated the commencement of construction and mining operations, and only US$0.1 million of capitalised costs were incurred during that period.

Net cash generated by financing activities amounted to US$3.5 million (31 December 2016: US$0.2 million). In addition to US$0.3 million of borrowing related to the Finbank Ltd BIF overdraft drawn in the period, the Company also successfully completed an equity placing in December 2017 for net proceeds of US$3.5 million (of which US$0.3 million was received shortly after the period end).


On 10 March 2017, the Company entered into an agreement with Obsideo Consulting Pty Ltd for the design, supply, and installation of a rare earths concentrator plant, for a total of ZAR 23.3 million (US$1.8 million). As at 31 December 2017, a total of US$1.5 million had been incurred under this contract, therefore US$0.3 million should be considered a capital commitment at the period end.


The Group continually monitors its exposure to currency risk. It maintains a portfolio of cash and cash equivalent balances mainly in pounds sterling and US dollars, which it holds primarily in Guernsey in call deposits.

Under Burundian law, the Company is required to repatriate the proceeds of its exports of concentrate, which are sold in US dollars, into Burundi. These funds will be used to settle ongoing operating costs in Burundi and abroad, and under the terms of the Mining Convention signed with the Government of Burundi in 2015, the Group’s legal entity in Burundi (Rainbow Mining Burundi SM) has the right to use its foreign currencies for all legitimate purposes, including settlement of invoices, intragroup loans, management fees, and dividends.

The Company does not therefore expect to hold significant balances of unused BIF or foreign currency in Burundi.

Going concern

The Directors have a reasonable expectation that the Company and the Group have adequate resources to continue in operational existence for the foreseeable future. Accordingly, they continue to adopt the going concern basis in preparing the Condensed Consolidated and Company Financial Statements. For further detail refer to the detailed discussion of the assumptions outlined in note 2(a) to the Condensed Consolidated Financial Statements.

Cautionary Statement:

The business review and certain other sections of this Half Yearly Report contain forward looking statements that have been made by the Directors in good faith based on the information available to them up to the time of their approval of this report. However they should be treated with caution due to inherent uncertainties, including both economic and business risk factors, underlying any such forward-looking information and no statement should be construed as a profit forecast.

Risks and uncertainties

There are a number of potential risks and uncertainties inherent in the mining sector which could have a material impact on the long-term performance of the Company and which could cause the actual results to differ materially from expected and historical results. The Company has taken reasonable steps to mitigate these where possible. Full details are disclosed on page 25 of the Annual Report for the year ended 30 June 2017. There have been no significant changes to the risk profile during the first half of the year. The risks and uncertainties are summarised below:

   --      Ramp up of the Kabezi plant

– Ramping up of production involves increasing the throughput of ore, and during this period it remains possible that issues will arise that will require remedial actions. In addition, construction work elsewhere on the plant site, such as warehouse and offices, continues.

   --      Production

– The process of mining and crushing/separating rare earth mineral concentrate at Gakara remains exposed to a number of risks including mechanical outages, supply issues, interruptions due to weather. These risks are higher during the early stages of production, when the processes are less well established

   --      Civil unrest 
   -       The risk of civil unrest exists in Burundi, which has experienced disturbances in the past 
   --      Rare earth prices

– Rainbow’s sales price for its mineral concentrate is derived from a basket price for the individual REOs it contains, less a deduction as negotiated with each customer. The ultimate selling price may therefore go up or down depending on market conditions

   --      Geological risk

– The scale and grade of the mineral deposit at Gakara cannot be stated with certainty, particularly as the Company has not yet declared a JORC-compliant Mineral Resource

   --      Financing risk

– Any substantial delays in production or adverse pricing may result in the requirement for short-term financing. At present the Company does not anticipate such a requirement, however this possibility remains a risk

   --      Currency controls

– All sales proceeds from mineral exports will be repatriated into Burundi. The Company is therefore exposed to the risk that access to its funds may be restricted either as a result of currency shortages, governmental policy changes, or international banking restrictions imposed on Burundi by banks or governmental bodies
