3rd APRIL 2018
Gold Exploration Projects – Maricunga Region, Chile
Vidalita Project
The drilling completed to 27 March in the 2018 exploration campaign is summarised in Table 1. To
27 March 2018, a total of 2,533 metres have been drilled.
Figure 1 – rig LF90D drilling diamond drill hole 5700-1
Exploration drilling has generated a large number of samples. Delays with sample preparation in
Chile has caused a backlog of drill assays for the project. Assays are expected to be available from
April. Results will be reported when received from the laboratory and assessed.
Included in this release are photographs of intervals of core that, based on the evidence of surface
rock sample results, could be mineralised. A brief comment is included below each photograph.

focusing on testing substantive mineralised systems capable of forming commercially attractive
development opportunities using existing technologies;
•
seeking to reduce risk by selecting operating environments with established minerals law and
mining industries;

About the gold projects, Maricunga Belt, Chile
The Vidalita and Jotahues gold projects are located in the Maricunga gold belt in the Atacama Region
in northern Chile hosting numerous world class gold and silver projects. Emu’s projects cover an area
of approximately 6,900 hectares secured by mineral exploration concessions and host alteration and
mineralisation that appear geologically similar to other high sulphidation gold deposits of the
Maricunga gold belt. The projects are accessed using a network of roads that link Copiapó with the
Refugio project (Kinross), Cerro Casale project (Barrick/Goldcorp) and the Caspiche project
(Goldcorp). Refugio is located 30 km to the northwest of Vidalita. Emu is unaware of the project
having been drilled other than for the 3 holes it drilled in 2017.
The Company holds an option (Option) to acquire a 100% interest in certain of the Vidalita and
Jotahues concession packages from two Chilean companies.
The concessions the subject of the Option comprise 2 packages: one package, (the Prospex SpA
concessions) covers six concessions at Vidalita, is subject to a 2% NSR on any production, and the
second package, (the BLC SpA concessions) comprised of three concessions at Jotahues and two
concessions at Vidalita (Vidalota A&B), is subject to a 1% NSR.
The royalties apply to any concession acquired by Emu within 5km of the outer boundary of any of
the interests listed in the Option agreement. Any concession interest within that area acquired by the
other parties to that agreement shall be offered to Emu on the same terms as the other party acquired
the same.
The Option will lapse if Emu fails to pay US$100,000 in November 2018. The Option may be
exercised in November 2019 on payment of US$2M following expenditure of US$1M, electing to
continue on or before November 2018 (by paying US$100,000 refer to above), the issue of 2.5M
Emu shares and then if Emu defines: (i) 0.5Moz of gold in measured resources, a further 5M ordinary
shares will be issued; and (ii) 1Moz of gold in measured resources, a further 5M ordinary shares will
be issued.
Emu continues to look for new mineral exploration, development and mining opportunities within
Australia and at various overseas jurisdictions.

Emu has an option agreement
dated 14 November 2016 with
two Chilean companies, Prospex
SpA and BLC SpA, to acquire 8
concessions at Vidalita and 3
concessions at Jotahues. This
option maybe exercised any time
up until November 2019 by
granting Prospex and BLC a 1%
NSR on production and allotting
them up to 15 million Emu
ordinary shares subject to certain
vesting conditions (see ASX
release 15th November 2016).
Prospex SpA in turn has an
option to acquire 6 of the 8
Vidalita concessions from local
Chilean parties. Under the terms
of that agreement, Prospex has
the right to exercise that option
by November 2019 by paying
US$2 million and granting the
Chilean parties a 1% NSR over
those 6 concessions. Under the
Emu option agreement, Emu has
assumed the rights and

Prior to the March 2017 drilling
program, no drilling is known on
these concessions. Previous work
was limited to rock sampling.
Geology
Deposit type, geological setting and style
of mineralisation.
The project is a green fields
exploration project and while the
source of the surface evidence of
mineralization can only be
speculation at this stage, it is
likely to be similar to known high
sulphidation epithermal style ore
deposits in the same geological
setting.

Information
A summary of all information material to
the understanding of the exploration
results including a tabulation of the
following information for all Material drill
holes:
Table included in the text
easting and northing of the drill hole
collar
elevation or RL (Reduced Level – elevation
above sea level in metres) of the drill hole
collar
dip and azimuth of the holes, down hole
length and interception depths hole length.
If the exclusion of this information is
justified on the basis that the information is
not Material and this exclusion does not
detract from the understanding of the
report, the Competent Person should
clearly explain why this is the case.
Data
aggregation
methods
In reporting Exploration Results,
weighting averaging techniques, maximum
and/or minimum grade truncations (eg
cutting of high grades) and cut-off grades
are usually Material and should be stated.
No drill assays at this time.
Where aggregate intercepts incorporate
short lengths of high grade results and
6
longer lengths of low grade results, the
procedure used for such aggregation
should be stated and some typical
examples of such aggregations should be
shown in detail.
The assumptions used for any reporting of
metal equivalent values should be clearly
stated.
Relationship
between
mineralisation
widths and
intercept lengths
These relationships are particularly
important in the reporting of Exploration
Results.
Project is at an early stage of
exploration and any conclusions
at this stage would be
speculation.
If the geometry of the mineralisation with
respect to the drill hole angle is known, its
nature should be reported.
If it is not known and only the down hole
lengths are reported, there should be a
clear statement to this effect (eg ‘down
hole length, true width not known’).

be included for any significant discovery
being reported. These should include, but
not be limited to a plan view of drill hole
collar locations and appropriate sectional
views.
Balanced
reporting
Where comprehensive reporting of all
Exploration Results is not practicable,
representative reporting of both low and
high grades and/or widths should be
practiced to avoid misleading reporting of
Exploration Results.
Not yet applicable – assays yet to

Other
substantive
exploration data
Other exploration data, if meaningful and
material, should be reported including (but
not limited to): geological observations;
geophysical survey results; geochemical
survey results; bulk samples – size and
method of treatment; metallurgical test
results; bulk density, groundwater,
geotechnical and rock characteristics;
potential deleterious or contaminating
substances.

Further work
