SUCCESSFUL EXPLORATION DRILLING AT RIVERINA PAVES THE WAY FOR MULTI-YEAR MINE LIFE EXTENSION

Highlights:

  • Deep drilling at Riverina Underground confirms continuity of high-grade gold mineralisation over 300m below the current mine plan, with the drill campaign still progressing

  • Extensional drilling from Riverina Underground extends mineralisation in central area resulting in immediate additions to mine plan

  • Potential new greenfields discovery at Little Gem, located 2.5km south along strike of Riverina Underground with first drill hole intersecting 3 parallel lodes, at good grade and width

  • Board has approved additional spend of $16 million in Exploration & Resource Development and $29 million in Capital to rapidly advance drilling and expand infrastructure

Ora Banda Mining Limited (ASX: OBM) (“Ora Banda”, “Company”) is pleased to provide an update on its continued exploration success at the high-grade Riverina Gold Camp.

Riverina Underground

Since October 2024, two surface diamond drill rigs have been drilling to test depth extents at the Riverina Underground as well as 2 underground drill rigs focussing on near mine extensions. These programs are approximately 50% complete, however have delivered significant results by extending known structure and mineralisation to over 1km deep, which is 800m below the current working level and 500m below current mine plan. In addition, the deep drilling has identified a high-grade shoot that is over 600m below current workings and 300m below current mine plan with intersections of 2.9m @ 36.0 g/t and 2.9m @ 18.9 g/t on the main lode and remains open at depth (see Figure 2).

Significantly, the latest drilling results demonstrate the continuity of the mineralised structures which remain open and display strong tenor and grade in the deepest holes. The main lode mineralised structure has been intersected in its anticipated position despite large step outs and drill hole depths in excess of 1km. The high-grade shoot style of the mineralisation is consistent with what is observed in the current underground workings.

Given the significantly under-drilled nature of the Riverina system, two underground diamond drill rigs have been focused on near mine extensions of the mineralised system that have minimal data. This drilling has been very successful with extension in the central “shark bite” adding two additional levels, with one of the best intersections returning 1.5m @ 62.3g/t (see Figure 5). Riverina Underground also continues to benefit from the multiple stacked lodes per level, with over 1,200m of ore driving available as shown in Figures 6 and 7.

Significant intercepts from exploration, resource extension and definition drilling include:

Ora Banda remains committed to expanding the known mineralisation system at Riverina and currently has two surface diamond drilling rigs and two underground diamond rigs dedicated to resource extension and definition drilling at Riverina Underground. Drilling continues to ramp up with further infill and extensional drilling planned ahead of anticipated Mineral Resource Estimate upgrades in H1 FY26.

Little Gem

Ora Banda has also embarked upon a grass roots exploration program 2.5km south of the Riverina Underground at the Little Gem prospect, as part of a State Government Exploration Incentive Scheme funded drilling program.

The initial hole was targeting stratigraphy 150m – 200m below surface and identified a potential new multi lode system (see Figures 9 and 10). The initial hole produced outstanding results with three intersections returned from three individually mineralised structures including:

  • 4.6m @ 7.4 g/t

  • 5.3m @ 3.3 g/t

  • 4.4m @ 3.4 g/t

A further 4 holes have been drilled at Little Gem that are currently awaiting assay return.

Importantly, the host rocks for these structures have been identified as the metasediment units that form part of the hanging wall sequence in the Riverina Underground. This sequence hosts the Murchison, Reggies and Durham lode systems. The actual basalt sequence that hosts the high-

2

grade Riverina ore lodes sits to the immediate west of the Little Gem discovery hole and is yet to be tested at this location.

Ora Banda geologists have continued to develop and evolve the exploration model associated with the Little Gem prospect and have planned additional holes to test the regional extent of this mineralisation.

Ora Banda Board Approved Expenditure

As a result of the outstanding drill results, the Ora Banda Board has approved additional spend of $45 million in FY25 to rapidly advance drill programs and infrastructure to support further growth as follows:

  • Additional $16 million on Exploration and Resource Development drilling to focus on further drilling at Riverina; this will take total exploration expenditure from $25 million planned in FY25 to $41 million

  • Additional $29 million in Capital expenditure to enhance and set infrastructure up for growth; this will take total Capital expenditure from $63 million planned in FY25 (including Sand King ramp up to steady state) to $92 million including:

  • ~$10 million in further camp expansions

  • ~$10 million in mine development including drill drives and support infrastructure

  • ~$9 million in ancillary projects

Ora Banda’s Managing Director, Luke Creagh, said:

"The significant results that are flowing from deeper drilling at Riverina Underground are nothing short of remarkable and point to a future step change for the business as we can now see through to a multi-year expansion in mine life.

"Equally as exciting has been the first hole, a potential greenfields discovery, at Little Gem. The tenor of Little Gem's mineralisation and its multi-lode structure exemplifies the highly prospective nature of the Riverina trend. We will be following up the discovery hole and other prospects to the south as a priority.

“With the potential value creation that extending and expanding Riverina presents, the additional exploration and capital spend approved by the Board sets Ora Banda on the path of rapidly realising further value from the drill bit”

Next Steps for Resource Development at Riverina Underground

Ora Banda remains commited to investing heavily in resource development drilling programs at the Riverina Undeground with the clear objective of growing the mine life (see Figure 8 below). The recent drilling has substantially extended the known boundaries of the main mineralised structures, however significantly more drilling is required to convert these highly encouraging results into a Mineral Resource Estimate and the subsequent Ore Reserve Estimate.

Two surface diamond drilling rigs and two underground diamond rigs dedicated to resource development drilling are continuing work at Riverina. Drilling will continue to ramp up with further infill and extensional drilling planned ahead of anticipated Mineral Resource Estimate upgrades in H1 FY26.

Exploration Drilling Update for the Little Gem Prospect

In October 2024 the Company undertook regional reconnaissance drilling around the greater Riverina area, following a successful grant received via the State Government, Exploration Incentive Scheme. This resulted in two holes being drilled, one at the Little Gem Prospect and the other at the Ace prospect.

The initial Little Gem hole (LGDD24001) was designed to test a major mineralised shear trending from Riverina Underground through to Sunraysia prospect 7.5 km to the south of Riverina. This shear runs parallel to and immediately east of the latest GSWA-interpreted position of the Ida Fault, but may also be related to this major regional structure. The hole was designed to intersect this shear beneath highly anomalous gold (19m @ 0.78g/t (EOH) including 7m @ 1.7g/t) intersected in aircore drilling during 2021 by Ora Banda.

Three significant high-grade gold zones were intersected in LGDD24001 (@ 1g/t lower cut):

  • 5.3m @ 3.3g/t Au (Inc. 0.8m @ 10.8g/t Au)

  • • 4.5m @ 7.4g/t Au (Inc. 1.5m @ 12.6g/t Au)

  • 4.4m @ 3.4g/t Au (Inc. 1.6m @ 6.7g/t Au)

These three intersections are associated with a distinct white brecciated carbonate unit.

An initial follow up program of diamond drilling at Little Gem, targeting extensions to the significant results from the EIS hole (LGDD24001), has been completed with 5 holes for 1,848.7m. All holes have intersected varying thickness of the preferred carbonate host unit. The carbonate lodes are consistent in strike and depth extent, with all holes intersecting carbonate units where expected. This has established >1.6km strike to the preferred host down to 400m vertical depth. All follow up holes are currently awaiting assay return.

Furthermore, the final hole (LGDD25005) intersected an additional lode ~200m to the east of the main Little Gem lodes, this is called the Sapphire lode and is supported by mapping and anomalous gold in historical AC drilling for a strike length of >1.7km.

Hole ACDD24001 at the Ace prospect was designed to intersect a North-South trending magnetic high anomaly corresponding to a perceived silica-magnetite-sulphide alteration halo within a diorite intrusive with coincident gold-copper auger anomaly directly overlying. Small historical gold workings occur in saprock overlying the magnetic anomaly.

Two significant gold zones were intersected in ACDD24001:

A narrow medium grade Au zone returning (@ 0.1g/t lower cut)

  • 2.4m @ 3.8g/t Au

  • Inc. 0.9m @ 7.8g/t Au

A broad zone of low-grade Au-Cu returning (@ 0.1g/t lower cut)

  • 83m @ 0.3g/t Au, 0.14% Cu, 1.4g/t Ag & 6.8ppm Mo

Appendix 2 - JORC CODE, 2012 EDITION – TABLE 1 REPORT TEMPLATE

Section 1 Sampling Techniques and Data - GREATER RIVERINA AREA

Information for historical (Pre Ora Banda from 1996 and 2001) drilling and sampling has been extensively viewed and validated where possible. Information pertaining to historical QAQC procedures and data is incomplete but of a sufficient quality and detail to allow drilling and assay data to be used for resource estimations. Further Ora Banda has undertaken extensive infill and confirmation drilling which confirms historical drill results. Sections 1 and 2 describe the work undertaken by Ora Banda and only refer to historical information where appropriate and/or available.

Criteria JORC Code explanation Commentary
Sampling
techniques		 •
Nature and quality of sampling (eg cut
channels, random chips, or specific
specialised industry standard
measurement tools appropriate to the
minerals under investigation, such as
down hole gamma sondes, or handheld
XRF instruments, etc). These examples
should not be taken as limiting the broad
meaning of sampling.
•
Include reference to measures taken to
ensure sample retrospectivity and the
appropriate calibration of any
measurement tools or systems used.
•
Aspects of the determination of
mineralisation that are Material to the
Public Report.
•
In cases where ‘industry standard’ work
has been done this would be relatively
simple (eg ‘reverse circulation drilling
was used to obtain 1 m samples from
which 3 kg was pulverised to produce a
30 g charge for fire assay’). In other
cases more explanation may be
required, such as where there is coarse
gold that has inherent sampling
problems. Unusual commodities or
mineralisation types (eg submarine
nodules) may warrant disclosure of
detailed information		 •

drill collar. Composite analytical samples (~3.5kg) were initially collected over 5m intervals for each hole and a 1m
bottom of hole analytical sample. Analytical composite samples were formed by taking a representative scoop
through each 1m drill sample. RC drill samples were collected in large plastic retention bags below a freestanding
cyclone at 1m intervals, with analytical samples initially formed by composite sampling over 5m intervals. Where
samples were dry, analytical composites were formed by spear sampling, using a 50mm diameter plastic pipe
pushed through the drill cuttings in the sample retention bag to the base of the bag. The pipe is removed carefully
with the contents of the pipe containing a representation of the retained metre. Wet RC drill samples where
thoroughly mixed in the sample retention bag and ‘scoop’ sampled to form a 5m composite sample. HQ diamond
core was cut into halves and sampled on geological boundaries, to a minimum of 20cm samples or on a metre
basis on site. The diamond core was cut using a diamond saw, with half core being submitted to the laboratory for
analysis and the other stored. Field samples were taken for RAB, RC and diamond core samples at a rate of 1 in 20.

Ora Banda Mining Limited – Up to April 2020, all samples were sent to an accredited laboratory (Nagrom
Laboratories in Perth, Intertek-Genalysis in Kalgoorlie or SGS in Kalgoorlie). The samples have been analysed by
firing a 50gm portion of the sample. This is the classical fire assay process and will give total separation of gold. An
ICPOES finish is used. Commercially prepared standard samples and blanks are inserted in the sample stream at a
rate of 1:12. Sizing results (percentage of pulverised sample passing a 75μm mesh) are undertaken on
approximately 1 in 40 samples. The accuracy (standards) and precision (repeats) of assaying are acceptable. For
drillholes RVRC20036 to RVRC20104, 1m and 4m composite RC samples were sent to MinAnalytical Laboratory
Services in Kalgoorlie. Sample prep involves drying and a -3mm crush, of which 500 grams is linear split into assay
jars for analysis. Samples are analysed by the Photon assay method which utilises gamma radiation to excite the
nucleus of the target atoms (gold). The excited nucleus then emits a characteristic photon, which is counted to
determine the abundance of gold in the sample. For all drilling after 2022, All samples were sent to the accredited
onsite SGS laboratory at Davyhurst for sample preparation. Prepared samples were then despatched to SGS
laboratories in Kalgoorlie for a 50g charge Fire Assay (GO_FAP50V10) with MP-AES finish. Commercially prepared
standard samples and blanks are inserted in the sample stream at an average rate of 1:25. Sizing results
(percentage of pulverised sample passing a 75μm mesh) are undertaken on approximately 1 in 20 samples. The
accuracy (standards) and precision (repeats) of assaying are acceptable. Standards and blanks were inserted into
the sample stream at a rate of approximately 1:12. Duplicates were submitted at a rate of approximately 1:30. The
accuracy (standards) and precision (repeats) of assaying are acceptable. Underground diamond drilling – All

sub-vertical lodes, holes are designed to optimise intersection angles and reduce bias for Main Lode East and West.
Some bias is present for the Murchison lodes, given their close proximity to the drill cuddies and this impact is
mitigated through detailed wall/backs mapping of Murchison lode intersections in underground workings and
future targeted grade control drilling. Little Gem drilling is orientated -50 to west, perpendicular the strike of the

Geology •
Deposit type, geological setting and
style of mineralisation.		 •
The geology of the Riverina area consists of an interlayered sequence of meta-basalts, meta-sediments and
ultramafics, rarely cross-cut by narrow pegmatite dykes. The local stratigraphy strikes roughly N-S with primarily
steep east to sub-vertical dips. The area has been affected by upper greenschist to lower amphibolite grade
metamorphism with many minerals exhibiting strong preferred orientations. All rock units exhibit strain via zones
of foliation, with strongly sheared zones more common in ultramafic lithologies. Contemporaneous strike faults
and late stage thrust faults have dislocated the stratigraphy and hence, mineralisation.
•
Gold mineralisation at Riverina is hosted by quartz-sulphide and quartz-Fe oxide veining primarily in the
metabasalts. Metasediments and ultramafics may also contain gold mineralised quartz veining, although much
less abundant. Gold mineralisation is also seen in silica-biotite-sulphide and silica-sericite-sulphide alteration
zones in the metabasalts.
•
The geology of Little Gem is entirely consistent of metasediments. Gold mineralisation is associated with
calcsilicate alteration. A Carbonate unit is consisted a highgrade host
Drill hole
Information		 •
A summary of all information

the exploration results including a
tabulation of the following
information for all Material drill
holes:

easting and northing of
the drill hole collar		 •
See list of drill intercepts.

o
elevation or RL (Reduced
Level – elevation above
sea level in metres) of the
drill hole collar
o
dip and azimuth of the
hole
o
down hole length and
interception depth
o
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.
•
Where aggregate intercepts
incorporate short lengths of high
grade results and 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.		 •
Original assays are length weighted. Grades are not top cut. Riverina resource is reported at a Lower cut off of
nominally 1.0g/t. Due to the narrow nature of mineralisation a minimum sample length of 0.2m was accepted when
calculating intercepts. Maximum 2m internal dilution. Exploration drilling Little Gem is reported at a lower cut off is
nominally 0.5g/t.
•
Metal equivalents not reported.
Relationship
between
mineralisation
widths and
intercept
lengths		 •
These relationships are particularly
important in the reporting of
Exploration Results.
•
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		 •
Intercept widths are down hole lengths. True widths are not reported given the varying orientation of drilling and
mineralisation at each deposit/prospect mentioned in the report.
•
The geometry of the mineralisation at Riverina and Little Gem is approx. N-S and sub vertical. Surface drilling is
oriented perpendicular the strike of the mineralisation. UG drilling from drill cuddy with hole radiating in fans.
Holes testing strike extremities are at lower angles to the ore lode and therefore not true widths, while those
perpendicular to the lode can approximate true widths.

38

should be a clear statement to this
effect (eg ‘down hole length, true
width not known’).
Diagrams •
Appropriate maps and sections
(with scales) and tabulations of
intercepts should 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.		 •
See plans, cross-sections and long sections.
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.		 •
The location of drill hole intersections is shown on the plans and 2D/3D diagrams and are coloured according to
grade to provide context for the highlighted intercepts
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.		 •
Riverina has no known reported metallurgical issues.
•
Results from previous processing have demonstrated that good gold recovery can be expected from conventional
CIL processing methods.
•
Recent baseline metallurgical test work demonstrated the following gold recoveries:
o
Oxide – 90%
o
Transitional – 97%
o
Fresh – 94.3%
•
Additional variation test-work remains ongoing.
Further work •
The nature and scale of planned
further work (eg tests for lateral
extensions or depth extensions or
large-scale step-out drilling).
•
Diagrams clearly highlighting the
areas of possible extensions,
including the main geological
interpretations and future drilling
areas, provided this information is
not commercially sensitive.		 •
Further GC drilling at Riverina underground will continue as the access into the mine is deepened.
•
Further resource definition drilling will be conducted from the surface, when beyond the reach of the underground
drills, aimed and continued mineral resource growth and resource conversion.
