HIGHLIGHTS
DMIRS CBLC Programme of Work (POW) Approvals
Field site work preparations underway
Drilling and service contracts executed
Estrella Resources Limited (ASX: ESR) (Estrella or the Company) is pleased to provide an update on the
Carr Boyd Nickel Project (CBNP or the Project). The CBNP is comprised of the Carr Boyd Layered Complex
(CBLC or the Complex).

The Company submitted via the DMIRS in March 2019 Programme of Work’s (POW’s) to drill the high
priority Target 5 EM anomaly which was generated by the Phase II moving loop HPEM late 2018. The
Company has received approvals from the DMIRS and drill preparations can now proceed in earnest.
The Company has executed drilling and service contracts to undertake the drilling and management of the
testing of Target 5 in the current quarter.
The target is compelling from both a geophysical and geological perspective having both a relative midhigh conductivity and nickel sulphides being identified in historic exploration drilling approximately 100m
south of the target area.
There are several historic high priority exploration targets and prospects in this area based on surface
geochemistry, downhole geochemistry, aero-magnetics, ground gravity, and interpreted geology datasets.
HPEM has defined two significant conductor’s indicative of the presence of well-developed
sulphides associated with two of the exploration targets, Target 5 and Target A.

Carr Boyd mine, advanced prospects (red dots), and targets (yellow dots) are also shown. The interpreted
basal contact is in a black dashed line.
TARGET 5
The first known report of this target appears in an internal company report written for Titan Resources in
2004. It is described again in an internal company report written for Yilgarn Mining in 2008.
The target is defined by a 450m long zone of highly anomalous nickel and copper mineralisation in drilling,
located approximately 100m south of the newly defined EM conductor. The mineralisation and EM
conductor appear to be located on or very close to the interpreted basal contact position of the CBLC.
Historic drilling does not appear to have tested the conductor defined by the recently completed Phase II
HPEM.
The EM conductor is discrete and moderately to highly conductive. The modelled conductance is 3000 –
5000S, making this a very high priority drill target.
Historic drilling returned many anomalous results over a 450m strike length of the interpreted basal contact
at Target 5. The best of which was 3.35m at 0.79% Ni and 0.35% Cu, including 0.61m at 2.12% Ni and
0.56% Cu from 100.89m in GD124.* This occurs in a zone of disseminated and matrix sulphide on the
interpreted basal contact of the CBLC. This is very positive support for the EM conductor located
approximately 100m along strike to the north.

ABOUT THE PROJECT AND THE CBLC
The CBLC is a 75km2 layered mafic igneous complex, which hosts several occurrences of nickel and
copper sulphides. The most significant occurrence discovered to date is at the Carr Boyd Rocks mine,
where mineralisation is hosted by bronzitite breccias (pyroxenites) emplaced within the gabbroic sequence
of the Complex. The CBLC is in a Tier 1 jurisdiction approximately 80km north north-east of Kalgoorlie
Western Australia. An all-weather haul road accessible by Estrella under a granted miscellaneous license
connects the Project to the Goldfields Highway via Scotia.
A “Voisey Bay” style model has not been adequately explored within the CBLC. This represents a
compelling exploration target opportunity which the Company will continue to aggressively pursue.

Competent Person Statement
The information in this announcement relating to Exploration Results, Mineral Resources or Ore Reserves is based on
information compiled by Luke Marshall, who is a consultant to Estrella Resources Limited, and a member of The
Australasian Institute of Geoscientists. Mr. Marshall has sufficient experience relevant to the style of mineralisation and
type of deposit under consideration, and to the activity he is undertaking to qualify as a Competent Person as defined
in the 2012 Edition of the “Australasian Code for Reporting of Exploration Results, Mineral Resource and Ore
Reserves”. Mr. Marshall consents to the inclusion in the report of the matters based on his information in the form and
context in which it appears.
