Lining of the Tailings Stor-

age Facility (TSF) under-

way with the plant in the

The process route at Balama

comprises crushing, grind-

ing, flotation, filtration, dry-

ing, screening and bagging.

Some of the flotation cells

are seen here.

With the inclusion of the Balama East

deposit, the 2013 estimate has grown substan-

tially with Syrah in May 2015 announcing

a total JORC-compliant resource of almost

1,2 billion tonnes at 11,0 % TGC for 128,5 Mt

of contained graphite and reserves of 81,4 Mt at

16,2 % TGC for 13,2 Mt of contained graphite.

The ore reserve figure has since increased by

40 % with Syrah reporting in November 2016

that proved and probable reserves now total

114,5 Mt at 16,6 % TGC for 18,6 Mt of con-

tained graphite.

Snowden delivered a full feasibility study

(FS) on the project in May 2015, which con-

firmed Balama as the world’s largest flake

graphite project. As detailed in the FS, Balama

will have a nameplate capacity of 350 000

tonnes of concentrate per annum at 98 %

TGC, with the reserves being sufficient for

over 40 years of operation at full production.

The average head grade will be approximately

19 % TGC during the first 10 years of opera-

tions. The FS estimated the IRR at 71 % with

a post-tax NPV

10

of US$1,1 billion and put the

payback period at less than two years from

commercial production.

The Balama mine is now at an advanced

stage of construction. Initial site clearing

started in 2015 and construction of the pro-

cessing plant in 2016. The key contractors on

the project are Kentz (part of SNC-Lavalin),

which is the SMP (Structural, Mechanical and

Piping) contractor, Tayanna Mozambique, the

mining contractor, and CMC Africa, responsible

for the civils. As at the end of November 2016,

the labour force on site numbered 1 435 people,

including 245 employees from the eight host

communities local to the mining concession.

In announcing the appointment of Kentz,

Syrah noted that the company had successfully

operated in Mozambique for 18 years and had a

proven track record of delivering major mining

and metals construction projects in the country.

These have included contracts for the Moma

mineral sands mine, the Moatize coal mine

and the Mozal aluminium smelter, as well as
