/CNW/ -
Outback Goldfields Corp
. (the "
Company
" or
"
Outback
") (TSXV: OZ) (OTCQB: OZBKF) is pleased to provide results from its reconnaissance-
style air-core drill program at its Yeungroon gold project ("
Yeungroon
" or the "
Project
"), central
Victoria, Australia
.
Highlights
Defined multiple broad corridors of elevated arsenic across the tenement
:
Numerous north-west trending zones of strong arsenic anomalism from top-of-bedrock
samples parallel to the Golden Jacket corridor have been defined northeast of the Golden
Jacket mine.
A strongly anomalous and open zone of high-arsenic, locally coincident with prominent
north-trending structural features, has been defined north of the unexplored Moondyne
target area.
Arsenic is a well established pathfinder element for high-grade gold mineralization across
the Victorian Goldfields.
Strongly anomalous gold values returned from multiple top-of-bed rock samples:
Anomalous gold results from air-core holes collared over 800 metres along trend to the
south of historical Golden Jacket mine suggest significant potential of the structure along
strike.
A broad zone of anomalous gold and arsenic from top-of-bedrock samples located over 1.4
kilometres north-east of the Golden Jacket mine define a new high-priority target area that
is open for expansion.
Deeper diamond drilling at both target areas is warranted to test for high-grade, structurally
controlled quartz reefs associated with the anomalous top-of-bedrock air-core samples.
"We are excited to update our shareholders on our exploration progress so far at our highly
prospective Yeungroon gold project,"
commented
Chris Donaldson
, CEO
. "The results of our multi-
rig drill program to date suggest that the historical Golden Jacket and Moondyne workings are not
isolated targets but appear to be part of a much larger gold system. Anomalous gold assays have
been identified for up to 800 metres south along strike of the Golden Jacket mine, and a new zone
of gold mineralization was discovered 1.5 kilometres to the northeast of the mine. More significant
is the identification of a new target zone on the western side of the tenement, near the Moondyne
reef-hosted gold target.
Although our current exploration focus is at our Ballarat West project, we will continue to evaluate
the new targets at Yeungroon and will plan additional exploration in the areas northeast of Golden
Jacket and near Moondyne. Our systematic and methodical approach to grassroots exploration
across the Victorian Goldfields is proving effective as we have now defined multiple new and
significant drill targets in areas that were previously unexplored."
Program Overview
The drill program comprised 968 metres of diamond drilling, 3,616 metres of RAB and 9,403 metres
of air-core drilling (see
March 30, 2022
news release). The focus of the composite drill program was
to investigate the structural setting and the dip- and strike-extent of reef-hosted gold mineralization
at the Golden Jacket mine as well as to map and sample the top-of-bedrock below shallow cover
across prospective trends and interpreted structural offsets identified in geophysical data from the
Golden Jacket and Moondyne target areas.
The highly portable air-core drill rig was used to sample and map the top of bedrock below cover. A
footprint of approximately 4.4 square kilometres was covered in the Golden Jacket grid and 8.5
kilometres of 100 metre spaced holes along road-side traverses were covered on the western side
of the property near the Moondyne target. Drill cuttings were analysed using a portable Xray
fluorescence spectrometer (pXRF). The focus for these analyses were pathfinder element
geochemical concentrations (e.g., arsenic). The relationship between gold mineralization and
disseminated arsenopyrite and high-arsenic contents in host rocks peripheral to gold-bearing quartz
reefs is well established throughout the Victorian Goldfields (e.g., Arne et al., 2008) and has been
used to focus exploration and vector to high-grade mineralization. Selected samples with anomalous
pathfinder elements were sent to the Gekko Assay laboratory for fire assay gold analyses. Samples
from 95 of the 591 air-core holes have been analysed for gold so far.
Based on results from this reconnaissance-style air-core drill program, multiple new drill targets have
been defined. The preliminary pXRF and gold fire assay results support the high-prospectivity of the
Yuengroon project. The Company is planning additional sampling and follow-up drilling to fully
investigate the gold mineralization potential of the Golden Jacket, Moondyne and O'Connors targets.
Golden Jacket Drilling Results
The Golden Jacket mine is associated with the property-scale, northwest-trending Golden Jacket
fault, which transects the property for over 30 kilometres of strike length. Historical small-scale
production from the Golden Jacket mine was reportedly 1,400 ounces of gold at approximately 250
grams per tonne (Bibby and More, 1998). Shallow air-core holes were drilled on a grid pattern
around the Golden Jacket Mine to explore for potential extensions and parallel zones of reef-hosted
gold mineralization.
The combined drilling program has defined possible extensions to mineralization along strike to the
south for up to 800 metres from the high-grade quartz reefs historically mined in the Golden Jacket
Mine (Figure 1). Anomalous gold values were from near top-of-bedrock chip samples that also
contained highly anomalous arsenic contents. This significant strike-length of gold and arsenic
anomalism represents a priority target area for deeper diamond drilling.
A new broad zone of gold mineralization was discovered approximately 1.5 kilometres to the
northeast of the Golden Jacket mine in an area that was previously undrilled and unexplored.
Samples were submitted to the lab for gold assay based on highly anomalous arsenic contents. This
area warrants additional drilling aimed at investigating possible structural controls to local gold
mineralization as well as expanding the grid to the north where the high-arsenic trends are open
(Figure 1).
Drill intercepts from the air-core program to date is given in Table 1.

Western Roadside Drilling Results
A series of roadside air-core drill hole traverses were completed on the western side of Yeungroon
to map and sample the top of bedrock along strike from the historic Moondyne gold workings as well
as across numerous project-scale, north-trending, structural corridors defined in geophysical data
(Figure 2). A summary of results from the western roadside drilling campaign is shown in Figure 2.
Figure 2 – Arsenic pXRF results of roadside air-core drilling in the western portion of the Yeungroon
tenement. The newly identified “O’Connors zone” Target is highlighted by the white dashed line, with
the Moondyne trend highlighted by the red dashed line. (CNW Group/Outback Goldfields Corp.)
The western roadside drilling program returned highly anomalous arsenic contents from zones along
trend from the Moondyne workings. These results suggest that the structural zone host to
mineralized quartz-reefs at Moondyne may extend for over 2 kilometres to the north.
A new target, O'Connors zone, has been identified between two splay faults off the project-scale
O'Connors fault (Figure 2). Air-core chip samples from across this structurally complex zone
returned highly anomalous arsenic contents covering a 1 kilometer east-west oriented transect. This
zone is within a broadly north-south trending structural corridor approximately 9 kilometres long
(Figure 2 and 3). Drill chips from this zone were also submitted for fire assay gold analysis. No
significant results were returned from this first batch of samples; however, most of the holes were
drilled to maximum depth of 15 metres on widely spaced 100 meter centres therefore the results
were not unexpected.
The relatively high-arsenic contents together with the broad, km-scale target footprint makes the
O'Connors zone a priority area for follow-up soil sampling, additional grid-based air-core drilling and
possible deeper diamond drilling.
Figure 3 - Peak arsenic grades in air core drill chip samples demonstrate a strong zone of arsenic
between splay faults off O'Connors Fault. (CNW Group/Outback Goldfields Corp.)

Yeungroon Project
The 698 km
2
Yeungroon project is transected by the north-trending, crustal-scale Avoca fault, which
separates the western Stawell zone from the Eastern Bendigo zone. The western side of the Project
contains the historic Golden Jacket hard-rock reef mine associated with the regional-scale,
northwest-trending Golden Jacket fault. Historical mining records indicate the Golden Jacket mine
produced quartz-rich ore with grades of up to 250 grams per tonne gold (Bibby and More, 1998),
however, the vertical and lateral extent of mineralization remains unknown.
The eastern side of the project is underlain by Ordovician rocks of the Castlemaine group and
comprises the northern extent of the Wedderburn Goldfield, where numerous small-scale, historical
alluvial and hard-rock mines are located.
Data Collection, Verification and QA/QC
Air core samples were collected in 1 metre intervals down hole from surface to end of hole for all
holes drilled. A representative sample of each 1 metre interval was collected in chip trays as drilling
was undertaken, as well as a larger sample (nominally 1.5kg) which was retained for additional
testing where required. Basic chip logging was carried out in the field by Company geologists. This
included sample lithologies, colour, quartz veining and mineral observations, and was completed
concurrent with sampling. All samples were transported from the drill site to the Company's
exploration office in Ballarat by Outback staff.
Preliminary analysis of the samples collected in chip trays was carried out using an Olympus Vanta
portable XRF. Analysis was carried out in "Geochem mode" running two beams for a total of 30
seconds each. Based on the results of the preliminary XRF Geochemical analysis, a number of the
larger 1.5 kg samples were submitted to the Gekko Assay Laboratory in Ballarat to be analysed for
gold using fire assay analysis. Entire samples were pulverised using an LM5 pulveriser ensuring that
90% of the sample was ground to less than 75 μm before 30g subset was taken for fire assay
analysis.
For both portable XRF analysis and Fire Assay analysis, QA/QC protocols involved the insertion of
Certified Reference materials and blanks at a minimum rate of 1 for every 50 samples tested.
Reference material was routinely tested with the portable XRF for arsenic concentrations and the
results were deemed acceptable for the scope of the exploration program and specifically identifying
anomalous results above background levels. Fire assay analyses of Certified Reference materials
for and blanks returned results within acceptable tolerances.
The Qualified Person has supervised all stages of the exploration program relevant to this news
release. This includes regular visits to the drill site to supervise, drilling, logging and sample
collection practices. The qualified person also supervised the analysis of Samples using the portable
XRF and performed a number of impromptu laboratory audits at the Gekko Assay laboratory.
