Preliminary Exploration Results
HIGHLIGHTS
* Additional mineralisation discovered that extends the footprint of the
Kwale South Dune Deposit to the south by 950m and east by up to a further
500m.
* Discovery of a new dunal mineral deposit at Mafisini, a continuation of the
Kwale South Dune Deposit mineralisation, with recorded intercepts over a
contiguous 1240m of strike and up to 480m in width.
* Discovery of new dunal mineralisation and marine sediments in the NE
Sector, adjacent to the Kwale Central Dune.
Base Resources Limited (ASX & AIM: BSE) ("Base Resources" or the "Company") is
pleased to provide preliminary exploration results of the extensional and
infill drilling program completed to date for its Kwale Mineral Sands
Operations ("Kwale Operations") in Kenya, East Africa. Strong drilling results
clearly demonstrate the potential to grow resources and mine life to the north
and south of existing project reserves.
As previously announced, the Company commenced an aircore drilling program in
the December 2016 quarter, within its Special Prospecting License 173 ("SPL 173
"). The drill program aims to provide mine life extension to the Kwale
Operations by exploring two previously identified prospective areas adjoining
or near the existing Kwale Operation ore bodies: the south-west sector ("SW
Sector") and north east sector ("NE Sector") (refer Figure 1).
An airborne geophysics program, conducted in 2015, covering the south coast
region of Kenya from Mombasa to the Tanzanian border, identified a series of
exploration targets that were subsequently confirmed through ground
reconnaissance. A summary of drilling completed to the 23rd February 2017 is
included in Table 1 and shown in Figure 1.
"Figures" (graphics) referenced in this release have been omitted. A full PDF
version of this release, including all Figures, is available from the Company's
website: www.baseresources.com.au.

SW Sector - Kwale South Dune Deposit extension & Mafisini Deposit
Exploration drilling in the SW Sector at Kwale has substantially increased the
dimensions of the South Dune Deposit and intersected a new dunal heavy mineral
sand deposit at Mafisini ("Mafisini Deposit") (refer Figure 2). The Kwale
South Dune Deposit has been extended a further 950m to the south at an average
of 700m across strike. The Mafisini Deposit is a continuation of the Kwale
South Dune mineralisation, separated from it by a narrow alluvial lowland.
Mafisini records mineralised intervals over a contiguous 1240m of strike and up
to 480m in width.
Visual inspection of the Kwale South Dune Deposit extension and Mafisini
Deposit mineralisation indicates a similar composition and high-value
mineralogy as that reported for the Kwale Operations Mineral Resources (134.6Mt
at 4.2% heavy mineral ("HM"), 26% slimes, 2% oversize and a HM assemblage of
59% ilmenite, 13% rutile and 6% zircon - refer ASX release 11th October
20161). Detailed mineralogy and resource estimation are expected to be
completed in the September quarter.
[Note 1: Refer to the "2016 Mineral Resources and Ore Reserves Update for
Kwale" released on 11 October 2016, which is available at http://
www.baseresources.com.au/investor-centre/asx-releases/. Base Resources confirms
that it is not aware of any new information or data that materially affects the
information included in the original market announcement and, in the case of
Mineral Resources and Ore Reserves, that all material assumptions and technical
parameters underpinning the estimates in the original market announcement
continue to apply and have not materially changed.]
Representative cross sections of the discoveries are included in Figures 3 and
4 (excluding infill holes) and significant drill intercepts are included in
Appendix 2.
NE Sector
Exploration drilling has commenced in the NE Sector, where the marine
escarpment falls away to the coastal plain (Figure 5). Initial results
indicate significant additional, high-value, mineralised dune accumulations
occur on the escarpment adjacent to the Kwale Central Dune Deposit (Figure 6).
Extensive community engagement has continued in the NE Sector to obtain
informed consent and access to the target drill sites located in this area.
However, increasing political positioning ahead of Kenya's general elections,
currently scheduled for August 2017, has produced community tensions not
conducive to exploration and so the Company has decided to postpone further
drilling until sentiment improves, likely to be after the elections.
Marine sediments have been intersected at the base of the escarpment in the NE
Sector at around 20m above sea level (Figure 6). Mineralisation (incl. 1.5m @
10.75% HM from 25.5m in ke001) has been discovered in what appears to be a
beach placer setting. The extent of the new discovery remains to be determined
by further drilling and is open in all axes.
Return of complete assays from the drilling in the NE Sector is awaited.
Mineralised intercepts received to-date are included in Appendix 2. Intensive
geological interpretation of down-hole results and further community engagement
will be conducted prior to further drilling in this region.
Kwale South Dune Deposit - edge definition and infill drilling
Base Resources has completed a program of edge-definition drilling along the
eastern margin of the Kwale South Dune Deposit (currently 88.5Mt @ 3.5% HM -
refer ASX/AIM Release 11th October 20162). Results suggest that the deposit
may be extended by as much as 500m east of its current location.
[Note 2: Refer to note 1.]
Additionally, an infill drill program has been completed to bring the Kwale
South Dune Deposit to a (nominally) 100m x 100m drill pattern, and provide the
basis for upgrading the geological confidence of Inferred and part of the
Indicated Resource areas of the deposit to a Measured status. Any Inferred
Resources achieving an Indicated or Measured Resource status will in turn be
eligible for inclusion within the Kwale South Dune Ore Reserves. Appreciable
Ore Reserve increases are anticipated from this work.
Detailed mineralogy and resource estimation are expected to be completed in the
September quarter.

The sample is then dried and weighed to

In the sample preparation area, at a
rate of 1:40, duplicates of the moisture
