exceeding the 18Mtpa plan.
- Record zircon recoveries.
- Ongoing supply constraints support continued strengthening of
rutile and ilmenite prices.
- Additional exploration licence applications submitted in
Kenya.
- No lost time or medical treatment injuries.
- Toliara Project DFS remains on schedule for completion in

African mineral sands producer, Base Resources Limited
(ASX & AIM: BSE) (Base Resources or the Company)
is pleased to provide a quarterly operational, development and
corporate update.
Kwale Mineral Sands Operations (Kwale Operations) in
Kenya successfully ramped up
mining operations at the South Dune orebody following the
transition from the fully depleted Central Dune orebody at the end
of June. As expected, mining commenced on the northern
fringes of the South Dune, where grades are lower, resulting in
reduced output of finished products. Ore grades improved
throughout the quarter as mining proceeded further into the
orebody.
The Toliara mineral sands project (Toliara Project) in
the south-west of Madagascar saw
sound progress on all workstreams and remains on schedule to
complete the definitive feasibility study (DFS) in
December 2019.

Mining operations were successfully commissioned on the South
Dune orebody, with mining ramp-up exceeding expectations with an
annualised mining rate of close to 20Mtpa achieved in the quarter,
higher than the 18Mtpa plan. Mined ore grade improved
throughout the quarter, from an average of 1.8% heavy mineral (HM)
in July to 3.6% in September, as all three mining units progressed
beyond the fringes of the orebody.

Wet concentrator plant (WCP) production of heavy mineral
concentrate (HMC) reduced to 114kt (last
quarter: 131kt) due to the lower mined ore grades. HMC
stockpiles were drawn down 9kt to close the quarter at 11kt as a
result of lower HMC production. HMC stocks started to
increase in September as mined ore grade increased. Sand
tails continued to be deposited into the mined-out Central Dune
area.

Mineral separation plant (MSP) feed rates were lower than
the prior quarter, reflecting the available HMC. The lower
feed rates in the quarter were partially offset by a higher
proportion of contained zircon in the HMC and higher recoveries for
most products, particularly zircon. The higher zircon
recovery is a function of the mineral properties encountered to
date in the South Dune, which contributed to improved separation
efficiency, as well as lower MSP feed rates enabling further
optimisation of the zircon wet circuit. A planned 14-day MSP
shutdown to replace the refractory linings in the HMC dryer took
place in July.
As mined ore grades, and consequently HMC production, improved
throughout the quarter, the MSP feed was increased to 84tph in
early October with the increased HMC production from the WCP, with
a consequent increase in output of finished product.
Bulk loading operations at the Company’s Likoni Port facility
continued to run smoothly, dispatching more than 72kt of ilmenite,
rutile and low-grade zircon during the quarter (last quarter:
145kt). Containerised shipments of rutile and zircon through
the Mombasa Port proceeded to plan.

Total operating costs were higher than the previous quarter due
to higher power costs associated with the additional mining volume
and pumping distance (US$0.8 million
higher than last quarter) and an increase in the non-cash
rehabilitation expense (US$0.5
million higher than last quarter) associated with clearing
of land ahead of mining activities. The higher total
operating costs, when combined with the lower production volumes,
resulted in a higher unit operating cost of US$173 per tonne produced (rutile, ilmenite,
zircon and low-grade zircon) (last quarter: US$127 per tonne).
Unit cost of goods sold is influenced by both the underlying
operating costs and product sales mix. Operating costs are
allocated to each product based on revenue contribution, which sees
the higher value rutile and zircon products attracting a higher
cost per tonne than the lower value ilmenite. Therefore, the
greater the sales volume of rutile and zircon relative to ilmenite
in a quarter, the higher both unit revenue per tonne and unit cost
of goods sold will be.
Ilmenite, and the majority of rutile, is sold in bulk, with
typical shipment sizes of 50-54kt for ilmenite and 10-12kt for
rutile, which means any given quarter will usually contain either
one or two rutile and ilmenite sales. Zircon is sold in
smaller parcels and sales generally align with production
volume. Product sales mix will therefore vary depending on
the number of bulk shipments of ilmenite and rutile in each
quarter.
Cost of goods sold of US$213 per
tonne sold (operating costs, adjusted for stockpile movements, and
royalties) was higher due to the higher operating cost per tonne
produced and sales mix (last quarter: US$180). The higher proportion of ilmenite
sold in the quarter contributed to a small reduction in the average
revenue per tonne to US$469 per tonne
(last quarter: US$482 per
tonne). From the combination of the above, the revenue to
cost of goods sold ratio for the quarter fell to 2.2 (last quarter:
2.7).
FY20 PRODUCTION GUIDANCE
Kwale Operations production guidance for FY20 remains unchanged
at:
- Rutile - 64,000 to 70,000 tonnes.
- Ilmenite - 315,000 to 350,000 tonnes.
- Zircon - 25,000 to 28,000 tonnes.
The above FY20 production guidance is based on the following
assumptions:
- Mining of 18.0Mt at an average HM grade of 3.58%, with all FY20
volume coming from Ore Reserves2.
- MSP feed rate at an average of 75tph.
- MSP product recoveries of 100% for ilmenite, 99% for rutile and
77% for zircon.
[Note (2): The Ore Reserves estimates
underpinning the above production targets were prepared by
Competent Persons in accordance with the JORC Code (2012
edition). The above production targets are the result of
detailed studies based on the actual performance of the Kwale mine
and processing plant. These studies include the assessment of
mining, metallurgical, ore processing, environmental and economic
factors.]
MARKETING
Ongoing constraints on the global supply of sulphate ilmenite
and high-grade chloride feedstocks (including rutile) have
maintained tight market conditions for titanium minerals resulting
in continued positive price momentum.
Chinese pigment production, no longer being materially
encumbered by environmental inspections and shutdowns, has
increased in 2019 which has led to strong demand for
ilmenite. It is understood that de-stocking by western
pigment consumers had largely run its course by the end of last
quarter. Global pigment producers have indicated that
underlying demand for pigment remains firm, albeit not as strong as
initially expected. Ongoing global economic uncertainties
appear to be leading to cautious pigment buying behaviour and a
preference for consumers to maintain low inventory levels. However,
demand is sufficient for most major chloride pigment producers to
continue operating at high production levels.
National and state government bans on private mining of mineral
sands in India are expected to
remain in place over the medium to longer term and will continue to
result in significant quantities of ilmenite being removed from the
market. No new ilmenite export quotas have been issued in
Vietnam which is also continuing
to impact global ilmenite supply. The emerging ilmenite
deficit, created by strong demand and supply restrictions,
continued to support a strengthening ilmenite price through the
quarter. Demand for Base Resources ilmenite from existing
customers remains greater than the Company’s ability to supply and
enquiries continue to be received from potential new customers
globally.
Ongoing constraints on high grade feedstock supply has continued
to support price improvement for rutile. Prices for Base
Resources rutile strengthened again in the quarter with further
improvements contracted for the December quarter.
The zircon market came under renewed pressure through the
quarter due to ongoing global economic uncertainties. Major
global suppliers of zircon are reported to have offered price
rebates and discounts to some customers for the remainder of the
2019 calendar year. As a result, the price for Base Resources
zircon in the coming quarter has been contracted at a slight
discount to September quarter prices.
SAFETY
With no lost time or medical treatment injuries occurring during
the quarter, or in the past year, Kwale Operations’ lost time
injury frequency rate (LTIFR) and total recordable injury frequency
rate (TRIFR) are both zero. No injuries were recorded in the
quarter for the Toliara Project and the total number of injuries of
any type since project commencement remains at zero. Compared
to the Western Australian All Mines 2017/2018 LTIFR of 2.0, this is
an exceptional performance reflective of the ongoing focus and
importance placed on safety by management. Base Resources’
employees and contractors have now worked 18.0 million man-hours
LTI free, with the last LTI recorded in early 2014. Further,
8.3 million hours have been worked without a medical treatment
injury.
COMMUNITY AND ENVIRONMENT
Agricultural livelihood programs at Kwale, run in conjunction
with partners Business for Development, DEG, FMO, Australia’s DFAT
and the Cooperative Bank of Kenya
continue to develop. During the quarter extensive discussions
were held with Australian clothing manufacturer and retail group
Cotton On and the Government of Kenya to explore opportunities for value
addition to the Kenyan cotton industry.
Crop harvesting, supported by Base Resources, of maize, green
grams, legumes, rice and sunflower is underway and yields look
promising. Unseasonal rains in September delayed cotton
harvesting.
Rehabilitation of the Tailings Storage Facility (TSF) outer wall
continues with good progress achieved. Local community groups
have increased the supply of grass seeds for the rehabilitation
process and earned significant income as a result. The
increasing participation of community groups for various activities
on site continues to have a positive impact on nearby
communities. Test work to formulate the water retention layer
“mix” required for successful rehabilitation of the Central Dune
sand landform was well advanced by the end of the quarter.
At the Toliara Project, three community water supply boreholes
have been drilled and construction of tank stands completed.
The installation of solar pumping equipment is currently underway,
with additional boreholes planned using drilling equipment donated
by Base Resources. With the planning formalities now
completed, construction of schools and medical facilities will
commence following identification of suitable local building
contractors.
Training programs continue to build capacity for the Toliara
Project with the intent of improving skills and increasing
opportunities for local people to secure jobs during construction
and beyond. Over 580 local people have now undergone training
programs including heavy equipment operation, wet trades,
agriculture and other courses aimed at increasing employability and
livelihoods. In addition to these programs, 25 young men and
women from the Toliara area recently travelled to the Kwale
Operation in Kenya to begin their
two-year apprentice programs.

Extensional exploration – Kenya
Mining tenure arrangements continue to progress with the Kenyan
Ministry of Petroleum and Mining as a precursor to an anticipated
updated Ore Reserve based on the expanded 2017 Kwale South Dune
Mineral Resource as announced on 4th October
20174.
A concept study for mining of the 171Mt North Dune resource
commenced during the quarter and, should the outcome be positive, a
pre-feasibility study will be commissioned in 2020.
Completion of the remaining drilling program (4,200 metres) in
the North-East Sector (Kwale East) of PL 2018/0119 remains
suspended pending community access being secured. Drill assay
results to date have shown potential for some limited extensional
economic resource close to the Central Dune (Bumamani), but this
remains subject to more detailed evaluation.
Drilling of the southern and central sections of the Vanga
Prospecting License (PL/2015/0042) was completed during the quarter
with limited mineralised intersections. Further drilling is
planned in the northern Vanga section once community access to the
remaining land areas is secured. A north eastern extension of
the Vanga Prospecting Licence is under application (App No/1753) to
cover further prospective ground which has since become
available. After wider prospectivity work, additional
prospecting license applications have been lodged for an area south
of Lamu (Apps No/2136, 2146 and 2153) together with an area in the
Kuranze region of Kwale county about 70 km west of the Kwale
Operation (App No/2123).
Expenditure on exploration activities in Kenya during the quarter was US$0.2 million (last quarter: US$0.4 million).
