Diamond Fields Announces First Mineral Resource for Beravina Project
Diamond Fields Announces First Mineral Resource for Beravina Project
Vancouver, B.C. (27 December 2018) – Diamond Fields Resources Inc. (TSX-V: DFR)
(“DFR” or the “Company”) is pleased to announce a maiden Inferred Mineral Resource
estimate (“Mineral Resource”) of 1.5 million tonnes grading 22.7% Zircon (ZrSiO4)
(equivalent to 15.3% ZrO2) for its Beravina project in Madagascar (“Beravina” or the
“Project”).
Sybrand van der Spuy, CEO, said “We are pleased to have achieved our objective of
completing a NI 43-101 compliant resource statement for the Beravina Project before the end
of the year. The resource statement is an important milestone in Beravina’s development and
clearly shows the high grade nature of the deposit. We are continuing with our work to test
the market for our product and also evaluate financing options for Beravina’s continued
advancement.”

The Mineral Resource was estimated using The Canadian Institute of Mining, Metallurgy and
Petroleum (CIM) Best Practice Guidelines and is reported in accordance with the 2014 CIM
Definition Standards, which have been incorporated by reference into National Instrument
43-101 – Standards of Disclosure for Mineral Projects.
The Mineral Resource is reported at a cut-off grade of 9% ZrO2, which is the lowest grade
block estimate within the mineralisation model. Given the relatively high grade of the
deposit, the qualified person considers that mineralisation at this cut-off grade (of 9%) will
satisfy the test for reasonable prospects for eventual economic extraction should present
market conditions remain.
The zircon mineralisation occurs within a zoned quartz-feldspar pegmatite. The
mineralisation is contained within the outer quartz-zircon zone that forms a roughly circular
outcrop on the Beravina hill. The mineralised zone was modelled as a sheath of
mineralisation with the hangingwall being towards the centre of the sheath and the footwall
being the outside of the mineralised zone. The mineralised zone plunges to the north at
between approximately 50° and 65° and is generally between 10m and 20m wide.
Eleven holes inclined at 50° and two vertical holes were drilled at Beravina in 2006 and
2011. These were subjected to a complete re-logging and resampling exercise by MSA in
2018. Ten of the holes intersected the mineralised zone. The drillholes are between
approximately 19m and 104m long. The drillhole intersections are aligned in two horizontal
lines; one on the north side and the other on the south side of the deposit.
The core samples taken by MSA were assayed at SGS Randfontein (South Africa). Samples
were dried and then crushed to 80% less than 2mm. A sub-sample of 500g was pulverised to
85% less than 75µm using a carbon steel ring and puck pulveriser. ZrO2 and HfO2 were
analysed using XRF with borate fusion, and ThO2 and U3O8 were analysed by ICP-MS with
sodium peroxide fusion. The samples were subjected to a quality control and assurance
process consisting of the laboratory’s internal processes as well as the insertion of blank and
certified reference material samples by MSA. The ZrO2 and HfO2 assays were confirmed
within close limits by completion of check assays on a representative number of samples by a
second laboratory (ALS Chemex in Vancouver).
A three-dimensional block model of the mineralised zone was created based on the drillhole
logging and assays, and the mapped outcrop. The grades of ZrO2, HfO2, ThO2 and U3O8
were estimated into the block model using inverse distance squared interpolation. Density
was estimated using a formula based on the estimated percentage of zircon. The Mineral
Resource was classified as Inferred largely due to the low number of mineralised
intersections and incomplete drill coverage of the deposit. The down-dip extent of the
Mineral Resource was limited to 50m from the deepest drillhole and the mineralisation is
open at depth.
The Company intends to file a full NI-43-101 Technical Report on its
website http://www.diamondfields.com and SEDAR within 45 days of this announcement.
The Mineral Resource information contained in this press release has been reviewed and
approved by Jeremy C. Witley, Pr. Sci. Nat. (Geological Science) of the MSA Group. Mr
Witley is a Qualified Person (as that term is defined by National Instrument 43-101) and is

Notes to Editors:
Diamond Fields Resources Inc. (“DFR”) is a TSX Venture Exchange listed exploration and mine
development company with assets in Madagascar and Namibia. In Madagascar, DFR is developing
the Beravina Project, an advanced high grade hard rock zircon exploration prospect located in the
west of the country, approximately 220km east of the port of Maintirano and near a state road. In
Namibia, International Mining and Dredging Holdings (Pty) Limited is undertaking an initial six
month (non-continuous) offshore diamond mining program on DFR’s ML 111 licence area. The ML
111 concession has a ten year mining licence, effective until 4 December 2025, and lies within
Luderitz Bay between Diaz Point in the south and Marshall Rocks in the north and at depths of 15 to
70 metres.
