EMU NL
IP SURVEY IDENTIFIES FURTHER HIGH-GRADE
GOLD-SILVER-COPPER POTENTIAL AT VIDALITA,
CHILE
27 March 2019
----- End of picture text -----

  • Re-interpretation of drill and Induced Polarisation (IP) geophysical data at Vidalita completed following recent outstanding gold assay of:

24m at 5 g/t gold and 28 g/t silver from 20m in hole 5300-8.

  • 3D interpretation of all Vidalita drilling defines a shallow north plunge to gold-silver mineralisation, open at depth over a 1km strike.

  • IP data defines a very consistent 1km long north-plunging anomaly below the surface at 150m to 300m depth.

  • One diamond hole, 5700-1 drilled by EMU in 2018, targeted the IP anomaly but intersected only its top edge, returning:

82 m at 0.2 g/t gold, 11 g/t silver and 0.12% copper from 174m;

including 1m at 0.8 g/t Au, 1049 g/t silver and 5.4% copper.

  • The IP targets may represent the system’s sulphide-rich core and may indicate potential for high-grade gold, silver and copper.

  • Diamond drilling has been planned to follow up the IP targets.

EMU NL
IP SURVEY IDENTIFIES FURTHER HIGH-GRADE
GOLD-SILVER-COPPER POTENTIAL AT VIDALITA,
CHILE
27 March 2019
----- End of picture text -----

Emu NL (ASX:EMU) is pleased to report re-interpretation, following Emu’s discovery hole, of drill and Induced Polarisation (IP) geophysical data at the Vidalita Prospect, Maricunga Belt, Chile, which has identified further high-grade gold targets. The discovery hole, 53008, returned results of:

24m at 5 g/t gold and 28 g/t silver from 20m.

The results and mineralisation style at Vidalita confirm excellent potential for discovery of a high-grade gold-silver deposit similar to Salares Norte (ASX announcement 8 March 2019).

A compilation of the updated drill database into 3D indicates a strong shallow, northnorthwest plunge trend to the gold-silver mineralisation (Figure 1). The mineralised trend occurs as an extensive zone of demagnetisation in the ground magnetic data which is interpreted to be caused by very large areas of extensive alteration associated with NNW trending structures and associated gold-silver mineralisation (Figure 2).

Induced Polarisation (IP) Geophysics Review

The IP geophysical method is principally used to identify areas of:

  1. intense disseminated sulphide development indicated by the chargeability data; and

  2. massive sulphide and/or massive clay alteration indicated by the resistivity data.

Only one diamond hole (completed by EMU in 2018) has tested the IP chargeability (Figure 3) and conductivity (Figure 4) anomalies. That hole, which only tested the top edge of those anomalies, intersected:

82m at 0.2 g/t gold, 11 g/t silver and 0.12% copper from 174m in hole 5700-1;

including 1m at 0.8 g/t Au, 1049 g/t silver and 5.4% copper.

The occurrence of bonanza silver and high-grade copper associated with very thick intercepts of gold mineralisation coincident with the IP anomalies is extremely encouraging. The strongest anomaly remains untested at depth.

A very consistent shallow, north-plunging trend to the IP is evident in the data for at least 1km strike and at depths between 150m and 300m below surface (Figure 1). These IP anomalies have not been effectively tested by previous diamond drill holes (Figure 1 and 5). It is possible that the IP anomalies represent a sulphide-rich core to the system at depth.

Next Steps

Emu is planning and prioritising diamond drilling to test these high-grade gold, silver and copper geophysical anomaly drill targets.

The aircore rig at Vidalita continues infill drilling to track the interpreted gold-silver-rich structures near surface along strike and down plunge as per the pre-season drill plot design. Drilling directed at specifically following up the discovery hole is in planning with a view to being undertaken this season. Further assay results are awaited.

About the Vidalita prospect, Maricunga Belt, Chile

The Vidalita prospect is located in the Maricunga gold belt in the Atacama Region in northern Chile hosting numerous worldclass gold and silver projects. Emu’s project in the Maricunga Belt covers an area of approximately 136 km[2] secured by mineral exploration and exploitation concessions that host alteration and mineralisation that appear geologically similar to other high sulphidation gold deposits of the Maricunga gold belt. The projects are accessed using established infrastructure of roads that link Copiapó (major mining town) with the Refugio project (Kinross), Cerro Casale project (Barrick/Goldcorp) and the Caspiche project (Goldcorp). Refugio is located approximately 30 km to the northwest of Vidalita.

Emu holds an Option to acquire a 100% interest in certain of the Vidalita and Jotahues concession packages from two Chilean companies; Prospex SpA and BLC SpA.

The Prospex area covers six concessions at Vidalita and is subject to a 2% NSR on any production. The Option may be exercised in November 2019 on payment of US$2M. 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.

The BLC SpA area comprises of three concessions (Jotahues and Vidalota A&B) and is subject to a 1% NSR. There is no Option payment to be made.

In addition, Emu has pegged a concession within its own right, Arroyo Ancho. Portions of this are subject to an area of influence inclusion into the Prospex Option.

Emu continues to look for new mineral exploration, development, and mining opportunities within Australia and overseas jurisdictions.

Vidalita Drilling

Section 1 Sampling Techniques and Data

Criteria Commentary
Sampling
techniques
Air core (AC) samples – samples are collected from the rig cyclone in a
bucket over each metre drilled. The larger in-tact core segments are
recovered and stored in core trays for logging and geological reference.
This material is not oriented.
The remaining fine material in the bucket is transferred to a sample bag
in total. This sample is usually around 1kg representing ~ 15 to 20% of
the mass of the 1m interval.
All samples are prepared at Actlabs in Copiapo where they are crushed
to 2mm, split to an 800g sample then pulverised and split again to 25g.
The final split is sent to Actlabs, Coquimba for analysis.
Drilling
techniques
Air core (AC) drilling using 75mm diameter bits.
Drill sample
recovery
Geological team makes a qualitative estimate (as good, moderate or
poor) of sample recovery for each one metre down hole sample interval.
Supervising geologist ensures that representative chip and AC samples
are collected during drilling.
Sampling is considered to be unbiased.
Logging Alteration, mineralisation, rock type, and structure, where evident, are
logged and recorded from the core drill samples.
Pieces of core recovered by the AC system are stored in core trays for
logging and geological reference.
Total hole length is logged.
Sub-sampling
techniques
and sample
preparation
AC samples (fines) from each one metre of drill hole is bagged up. The
sample is usually around 1kg.
The 1m samples are prepared for analysis by standard laboratory
procedures.
Sub-sampling at the sample processing facility is done using splitters.
The samples collected are representative of the in situ material.
Sample sizes are appropriate to the grain size of the material being
sampled.

Quality of
assay data
and
laboratory
tests
A 25g split from each one metre AC pulp is taken from four consecutive
one metre samples, combined, re-pulverised to homogenise and a 25g
split is taken for analysis.
All samples are digested using 25g aqua regia and analysed using ICP-
MS at Actlab’s laboratory in Coquimba. Select samples are re-analysed
using Fire assay techniques.
All drill samples results are reported.
The aqua regia digest in this instance is considered appropriate given the
stage of the program and the altered nature of the rocks.
10% of drilling samples will be sent for check analysis to another
laboratory.
Laboratory standards and repeats are used to for QA/QC.
Verification of
sampling and
assaying
Highly anomalous four metre composites are identified and the one metre
samples from which they were composited sent to an alternative
laboratory for assaying.
No twinned holes have been drilled.
All geochemical and geological data is loaded into databases managed
by independent third party entities for verification, storage and plotting.
Assay data are not adjusted.
Location of
data points
Drill hole collars are located using hand held GPS accurate to < 5m in the
first instance. Holes are subsequently surveyed in using DGPS accurate
to <0.02m.
WGS 84 UTM zone 19J (south) grid system
Topographic control is deemed adequate at this stage of the exploration
program.
Data spacing
and
distribution
The drill holes are irregularly spaced (but generally >100m) as they are
testing geological, geophysical or geochemical targets.
No mineral resources are being reported at this time.
The AC samples are composited into four metre composites in the
laboratory.
Orientation of
data in
relation to
geological
structure
Drill hole azimuth was planned on indications of outcrop and/or subcrop
geology and lithological strike as indicated by a ground magnetic survey
and geologic mapping.
The controls on mineralisation are unknown at this time.
Sample
security
Emu management supervises sample collection and delivery to the
laboratory.
Audits or
reviews
None undertaken.

Section 2 Reporting of Exploration Results (Criteria listed in the preceding section also apply to this section.)

Criteria Commentary
Mineral
tenement and
land tenure
status
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 15thNovember 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 taken an assignment of the rights and assumed
the obligations of Prospex in relation to those 6 concessions. The option
agreements are subject to a 5km AOI from the boundaries of the
11 concessions. Since entering into the option agreement with Prospex
and BLC, additional concessions have been applied for and were
reported in subsequent ASX releases.
Exploration
done by other
parties
Previous work was limited to rock sampling. There had been no drilling
in the area prior to Emu’s activities.
Geology The prospect area is located within the early to late Miocene volcanics
of the Maricunga Belt. The project is a green fields exploration project
however the mineralisation style intersected in drilling is interpreted to
be similar to known high sulphidation epithermal style ore deposits in the
same geological setting. Rocks consist of volcanically derived
lithologies, including tuffs, andesites, dacites, polymictic and monomictic
breccias, and minor sedimentary facies associated with volcanic crater
development. Major north-north-west trending faults may control the
extent of mineralisation and provide the bounds to that mineralisation.
Lesser cross-cutting faults, generally north-easterly, appear to affect
mineralisation plunge and repetitions.
Drill hole
Information
See ASX announcement on 8 March 2019.
Data
aggregation
methods
Simple averages are calculated from mineralised zones.
Gold zones above 0.2ppm are aggregated within the mineralised zones
to calculate average gold intersections. Barren zones less than one
sample interval may be included in a composite aggregation if occurring
within the overall mineralised zone.
