Another Booming Gold Hit from RAS
Santana Minerals Ltd (Santana, ASX/NZX: SMI or the Company) is pleased to advise that the latest drill
intercept from infill drilling of the high grade-core at RAS has returned one of the best results to date:
▪ MDD326 41.6m @ 8.6g/t Au from 164.4m (true width 38.8m)
Santana CEO, Damian Spring said:
“With every hole we drill into RAS the outcomes just get better! We drilled this latest series of holes
with intent to constrain the bonanza results within our high-grade core. They have shown it to be
bigger and more continuous than we originally thought and this better-defined high-grade core will
now form the foundation of our early production planning for the future mine.”

The infill drilling program focussed on the high-grade core and was planned to address the impacts of
high-grade projection during resource modelling. Rather than show we needed to constrain the
impact, the drilling has proved a consistent, rich, tabular core exists.
The high proportion of gold metal in this bonanza zone which is now infilled to approximately 25m
hole spacings is extraordinarily high. This portion of the high-grade core has been infilled over 350m
of strike with the 200 gram x metre core being approximately 100m wide.
The results of all holes in the program including the last in this initial campaign are tabulated below:

Our drilling focus has now turned to resource definition drilling aimed at upgrading the Come-in-Time
satellite deposit into the Indicated JORC resource category for potential inclusion in ongoing mine
optimisations.
Drill rigs are also completing a number of geotechnical holes required for establishment of
infrastructure on the site. The Company remains focused on completion of the PFS in the December
quarter.
Ends.

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
representivity 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.
This Mineral Resource Estimate (MRE) is estimated from drilling samples collected by reverse circulation
and diamond drilling. ‘Blasthole’, surface trench and underground channel samples were used as an aid
for geological interpretation and domaining but not for grade estimation.
Diamond drill (DD) core samples for laboratory assay are typically 1 metre samples of diamond saw cut ½
diameter core. In the rare cases where the core was friable or unconsolidated the sample was collected
from one side of the core using a scoop. Where distinct mineralisation boundaries are logged, sample
lengths are adjusted to the respective geological contact. RC samples were sub-sampled at 1.0 m intervals
using a rotary splitter mounted below the cyclone. The splitter produced 2 x 30% splits and 1 x 40% split.
The two 30% splits were used as primary sample and field duplicate (if submitted) with the 40% split used
for logging and then stored at the MGL core yard.
Samples are crushed at the receiving laboratory to minus 2mm (85% passing) and split using a rotary
splitter to provide 1kg for pulverising in a ring mill to -75um. Pulps are fire assayed (FAA) using a 50g charge
with AAS finish. Prior to 2019 only 200g of the crushed material was pulverised. 877 samples were assayed
this way.
Certified standards, blanks and field replicates are inserted with the original batches at a frequency of ~5%
each for QAQC purposes.
All pulps and crush reject (CREJ) are returned from the laboratory to MGL for storage on site. Of these
returned samples, a further ~5% are re-submitted as QC check samples which involve pulp FAA re-assays
by the original and an umpire laboratory and CREJ re-assayed by 500-gram (+ & -75mu) screen fire assay
(SFA), 1kg BLEG (LeachWELL) and 2*500-gram Photon analysis (PHA) for gold.
Where multiple assays exist for a single sample interval, larger samples are ranked in the database: PHA >
BLEG > SFA > FAA.
All returned pulps are analysed for a suite of 31 elements by portable XRF (pXRF).
The sampling, sub-sampling and assaying methods are appropriate to the geology and mineralization of
the RAS deposit.
Criteria JORC Code explanation Commentary
Drilling techniques
Drill type (eg core, reverse circulation, open-hole
hammer, rotary air blast, auger, Bangka, sonic, etc) and
details (eg core diameter, triple or standard tube, depth
of diamond tails, face-sampling bit or other type,
whether core is oriented and if so, by what method,
etc).
Current drilling techniques are diamond coring (DD) PQ3 and HQ3 size triple tube. Where PQ3
core size (83mm diameter) is commenced this is maintained throughout the DD hole until
drilling conditions dictate reduction in size to HQ3 core (61mm diameter). DD pre-collars are
drilled open hole through un-mineralised TZ3 schist to within about 15 m of the mineralisation
hangingwall at which point diamond coring commences.
RC drilling is only carried out where the mineralisation target is less than about 150m downhole
and used a face sample bit with sample collected in a cyclone mounted over a rotary splitter
producing 2 x 30% splits and 1 x 40% split. The two 30% splits were used as primary sample and
field duplicate (if submitted) with the 40% split used for logging and then stored at the MGL
core yard.
Drillholes are oriented to intersect known mineralised features in a nominally perpendicular
orientation as much as is practicable.
All drill core is oriented to assist with interpretation of mineralisation and structure using a Trucore
orientation tool.
Drill sample recovery
Method of recording and assessing core and chip
sample recoveries and results assessed.
Measures taken to maximise sample recovery and
ensure representative nature of the samples.
Whether a relationship exists between sample recovery
and grade and whether sample bias may have occurred
due to preferential loss/gain of fine/coarse material.
DD core sample recoveries are recorded by the drillers at the time of drilling by measuring the
actual distance of the drill run against the actual core recovered. The measurements are
checked by the site geologist.
When poor core recoveries are recorded the site geologist and driller endeavour to immediately
rectify any problems to maintain maximum core recoveries.DD core logging to date indicate
~96% recoveries.
RC sample recovery is measured as sample weight recovered. RC sample moisture for all RC
drilling data was logged as dry (83.7% of RC samples), moist (12.0%) or wet (4.3%). All samples
logged as wet were omitted from use in this MRE.
The drilling contract used states for any given run, a level of recovery is required otherwise
financial penalties are applied to the drill contractor to ensure sample recovery priority along
with production performance.
Sample grades were plotted against drilling recovery by drilling method and no relationship was
established.
Wet RC samples do show higher grades than dry RC samples. This may be due to wet RC samples
coming from higher grade zones or sampling bias due to the loss of fines in wet samples.
Whatever the cause, this bias was the reason that wet RC samples were omitted from use in
this MRE.
Criteria JORC Code explanation
Commentary
Logging
Whether core and chip samples have been geologically
and geotechnically logged to a level of detail to support
appropriate Mineral Resource estimation, mining
studies and metallurgical studies.
Whether logging is qualitative or quantitative in
nature. Core (or costean, channel, etc) photography.
The total length and percentage of the relevant
intersections logged.
All DD holes have been logged for their entire sampled length below upper open hole drilling
(nominally 0-450 metres below collar). Data is recorded directly into AcQuire database with
sufficient detail that supports Mineral Resource estimations (MRE).
Logging is mostly qualitative but there are estimations of quartz and sulphide content and
quantitative records of geological / structural unit, oxidation state and water table boundaries.
Oriented DD core allows alpha / beta measurements to determine structural element detail
(dip / dip direction) to supplement routine recording of lithologies / alteration / mineralisation
/ structure / oxidation / colour and other features for MRE reporting, geotechnical and
metallurgical studies.
All RC chips were sieved and logged for lithology, colour, oxidation, weathering, vein
percentage and sulphide minerals.
All core is photographed wet and dry before cutting. Sieved RC chips are also photographed.
100% of all relevant (within the gold grade domains) intersections were logged. The logging is
of sufficient quality and detail for resource estimation.
Sub-sampling techniques
and sample preparation
If core, whether cut or sawn and whether quarter, half or
all core taken.
If non-core, whether riffled, tube sampled, rotary split,
etc and whether sampled wet or dry.
For all sample types, the nature, quality and
appropriateness of the sample preparation technique.
Quality control procedures adopted for all sub-
sampling stages to maximise representivity of samples.
Measures taken to ensure that the sampling is
representative of the in situ material collected,
including for instance results for field duplicate/second-
half sampling.
Whether sample sizes are appropriate to the grain size
Industry standard laboratory sample preparation methods are suitable for the mineralisation
style and involve oven drying, crushing and splitting of samples to 1kg for pulverising to -75um.
Pulps are fire assayed (FAA) using a 50g charge.
50g charge is considered minimum requirement for the coarse nature of the gold. Larger screen
fire assays (SFA), 1kg BLEG (LeachWELL) and 2*500gm Photon Analyses (PHA) are conducted
periodically as a QAQC check.
Field duplicates of RC samples are sub-sampled by a splitter as described above at the time of
sampling.
Large diameter (83mm) PQ3 core was maintained (where conditions allow) for DD holes to
MDD016 and subsequently HQ3 (61mm) for drillholes MDD017 onwards.
DD core drill samples are sawn in ½ along the length of the core on cut lines marked by
geologists’ perpendicular to structure / foliation or to bisect vein mineralisation for
representative samples whilst preserving the orientation line. Intervals required for QAQC

of the material being sampled. checks are nominated by geologists and the crushed sample being split by the laboratory with
the two replicated samples then assayed.
QA procedures used to maximise the representivity of sub-samples include the use of a cone
splitter on the RC rig and cutting DD core perpendicular to the regional foliation. QC procedures
to assess the representivity of sub-sampling include field replicates, standards, and blanks at a
frequency of ~5% and also cross-lab assay checks at an umpire laboratory.
The mass proportion of every 10th sample passing 75um is reported by the laboratory and
monitored to ensure sample preparation quality.
Calculations based on Pitard (1993) show that sub-sample masses are appropriate to gold
particle size and grade, if the size and shape of the gold particles are reduced in the ring mill in
a similar way to the gangue particles.
Quality of assay data and
laboratory tests
The nature, quality and appropriateness of the assaying
and laboratory procedures used and whether the
technique is considered partial or total.
For geophysical tools, spectrometers, handheld XRF
instruments, etc, the parameters used in determining
the analysis including instrument make and model,
reading times, calibrations factors applied and their
derivation, etc.
Nature of quality control procedures adopted (eg
standards, blanks, duplicates, external laboratory
checks) and whether acceptable levels of accuracy (ie
lack of bias) and precision have been established.
SFA and PHA are all total gold assays and are appropriate to the RSSZ mineralization. DD core
and RC chip samples for gold assays undergo sample preparation by SGS laboratory Westport
and 50g fire assay with an AAS finish (SGS method FAA505 DDL 0.01ppm Au or FAD505 DDL
1ppm Au & FAD52V DDL 500ppm Au) by SGS laboratory Waihi. Other SGS laboratories at
Macraes and Townsville and the ALS laboratory in Townsville, are used from time to time and
follow the same processes. For laboratory QAQC, samples (3*certified standards, blanks and
field replicates) are inserted into laboratory batches at a frequency of ~5% respectively. A
selection of 5% of retained lab pulps across a range of grades are sent for re-assay and to an
umpire laboratory for cross-lab check assays.
Portable XRF (pXRF) instrumentation is used onsite (Olympus Innov-X Delta Professional Series
model DPO-4000 equipped with a 4 W 40kV X-Ray tube) primarily to identify arsenical samples
(arsenic correlates well with gold grade in these orogenic deposits). The pXRF analyses a 31-
element suite (Ag, As, Bi, Ca, Cd, Cl, Co, Cr, Cu, Fe, Hg, K, Mn, Mo, Nb, Ni, P, Pb, Rb, S, Sb, Se, Sn,
Sr, Th, Ti, V, W, Y, Zn, Zr) utilising 3 beam Soil mode, each beam set for 30 secs (90 secs total).
pXRF QAQC checks involve regular calibration (every 20 samples) and QAQC analyses of SiO2
blank, NIST standards (NIST 2710a & NIST 2711a), & OREAS standards. pXRF QAQC checks
involve regular calibration (every 20 samples) and QAQC analyses of SiO2 blank, NIST standards
(NIST 2710a & NIST 2711a), & OREAS standards.
No geophysical tools have been used in this MRE.
Verification of sampling
and assaying
The verification of significant intersections by either
independent or alternative company personnel.
The use of twinned holes.
Documentation of primary data, data entry procedures,
data verification, data storage (physical and electronic)
protocols.
Discuss any adjustment to assay data.
Significant gold assays and pXRF arsenic analyses are checked by alternative senior company
personnel. Original lab assays are initially reported and where replicate assays and other QAQC
work require re-assay or screen fire assays, the larger sample results are adopted. To date
results are accurate and fit well with the mineralisation model.
Twinned data is available where DD core holes have been sited adjacent to previous RC
drillholes and where DD redrills have occurred.
pXRF multi-element analyses are directly downloaded from the pXRF analyser as csv electronic
files. These and laboratory assay csv files are imported into the database, appended and merged
with previous data.
Since October 2022 all logging has been directly entered into the Acquire database using tablets.
All collar surveys, downhole surveys and assay results are provided digitally and directly
imported into the database. On import into the database validation checks are made for:
interval overlaps, gaps, duplicate holes, duplicate samples and out of range values. The AcQuire
database is stored on a cloud server and is regularly backed up, updated and verified by an
independent qualified person.
The only adjustment made to the data on import to the database is to convert below detection
results to negative the detection limit. Samples with multiple Au results are ranked by assay
method (SFA > FA > other) and on export only the highest ranked method is exported. Prior to
import into Minesight software the data is further validated as above plus checks on the highest
and lowest values. Negative below detection results are converted to half the detection limit
on import into Minesight.
Location of data points
Accuracy and quality of surveys used to locate drill
holes (collar and down-hole surveys), trenches, mine
workings and other locations used in
Mineral Resource
estimation.
Specification of the
grid system used.
Quality and adequacy of topographic control.
All drillhole collar locations are accurate (+/- 50mm) xyz coordinates when captured by an
experienced surveyor using RTK-GPS equipment.
All drill holes reference the NZGD2000 NZTM map projection and collar RLs the NZVD2016 vertical
datum.
DD down hole surveys are recorded continuously with a Precision Mining and Drilling “North-
seeking” Gyro downhole survey tool. RC holes are surveyed at 12m intervals using a Reflex
multi-shot camera.
There are very minor historical adits and shafts at RAS. No surveys of these voids exist, although
at least one adit is still accessible. Historical production records total 630.5 tons of ore crushed.
Such small volumes are not material to this MRE.
Topographic control is provided by LiDAR topographic surveys in 2018 and 2021 covering the
entire project area. These are very accurate and suitable for resource estimation.
Data spacing and
distribution
Data spacing for reporting of Exploration Results.
Whether the data spacing and distribution is sufficient
to establish the degree of geological and grade
continuity appropriate for the Mineral Resource and
Ore Reserve estimation procedure(s) and classifications
applied.
Whether sample compositing has been applied.
Drill collar site locations in steep terrain are dictated by best access allowed by contour tracks
with gradients to allow safe working access and drill pad excavations. Drillhole designs take into
account this variation to achieve evenly spaced intercepts at the hangingwall of the
mineralisation.
Drillhole intersection spacing on the hangingwall of the mineralisation is typically 30 m (EW) by
30 m (NS) but varies from 20 m (EW) by 20 m (NS) in closely spaced areas to 120 m (EW) by 100
m (NS) in widely spaced (inferred) areas. This spacing is considered appropriate for determination
of geological and grade continuity at the mineral resource categories reported.
Some of the RC drilling was sampled as 4m composites and later re-sampled if the composite
result exceeded a threshold. There are no composited samples within the gold grade estimation
domains and so no composited samples were used in this MRE.
Sampling and assaying are in one metre intervals or truncated to logged features.
Orientation of data in
relation to geological
structure
Whether the orientation of sampling achieves unbiased
sampling of possible structures and the extent to which
this is known, considering the deposit type.
If the relationship between the drilling orientation and
the orientation of key mineralised structures is
considered to have introduced a sampling bias, this
should be assessed and reported if material.
Drillholes are oriented to intersect known mineralised features in a nominally perpendicular
orientation as much as is practicable. True widths are estimated perpendicular to mineralisation
boundaries where these limits are known. As the deposits are tabular and lie at low angles,
there is not anticipated to be any introduced bias for resource estimates.
Sample security
The measures taken to ensure sample security.
Company personnel manage the chain of custody from sampling site to laboratory.
DD drill core samples are transported daily from DD rig by the drilling contractor in numbered
core boxes to the Company secure storage facility for logging and sample preparation. After
core cutting, the core for assay is bagged, securely tied, and weighed before being placed in
polyweave bags which are securely tied. Retained core is stored on racks in secure locked
containers. RC samples are also place in polyweave bags and secured with zip ties.
Polyweave bags with the calico bagged samples for assay are placed in plastic cage pallets,
sealed with a wire-tied cover, photographed, and transported to local freight distributer for
delivery to the laboratory. On arrival at the laboratory photographs taken of the consignment
are checked against despatch condition to ensure no tampering has occurred.
Audits or reviews
The results of any audits or reviews of sampling
techniques and data.
An independent Competent Person (CP) conducted a site audit in January 2021 and December
2022 of all sampling techniques and data management. No major issues were identified, and
recommendations have been followed.
In February 2023 Snowdon Optiro completed a desktop review of the assay methods and QC
sample results and in its report concluded that the sampling and assaying methods are in line
with standard industry procedures and that that the assay data in the supplied database is
suitable to be used as the basis for a Mineral Resource.

Access arrangements are in place with landowners that provide for current exploration and
other activities, and any future decision to mine. As such, compensation is payable, including
payments of up to $1.5M on a decision to mine, plus total royalties starting at 1% on the net
value of gold produced, increasing to 1.5% and ultimately 2% dependent on location and total
gold produced over the life of the mine. The royalties are also subject to pre-payment of up to
$3M upon commencement of mining operations.
Exploration done by other
parties
• Acknowledgment and appraisal of
exploration by other parties.
Early exploration in the late 1800’s and early 1900’s included small pits,
adits and cross-cuts and alluvial mining.
Exploration has included soil and rock chip sampling by numerous companies since 1983 with
drilling starting in 1986. Exploration in the 1990’s commenced with a search for Macraes style
gold deposits along the RSSZ. Drilling included 13 RC holes by Homestake NZ Exploration Ltd in
1986, 20 RC holes by BHP Gold Mines NZ Ltd in 1988 (10 of these holes were in the Bendigo
Reefs area which is not part of the MRE area), 5 RC holes by Macraes Mining Company Ltd in
1991, 22 shallow (probably blasthole) holes by Aurum Reef Resources (NZ) Ltd in 1996, 30 RC
holes by CanAlaska Ventures Ltd from 2005-2007, 35 RC holes by MGL in 2018 and a further 18
RC holes by MGL in 2019.
Geology
• Deposit type, geological setting and style of
mineralisation.
The RSSZ is a low-angle late-metamorphic shear-zone, presently known to be up to 120m thick.
It is sub-parallel to the metamorphic foliation and dips gently to the north- east. It occurs within
psammitic, pelitic and meta-volcanic rocks.
The hangingwall of the RSSZ is truncated by the post metamorphic and post mineralisation
Thomsons Gorge Fault (TGF). The TGF is a regional low-angle fault that separates upper barren
chlorite (TZ3) schist from underlying mineralised biotite (TZ4) schists.
Gold mineralisation is occurs in the RSSZ as 4 known deposits with Mineral Resource Estimates
(MRE) – Come-in-Time (CIT), Rise and Shine (RAS), Shreks (SHR) and Shreks-East (SRE). The gold
and associated pyrite/arsenopyrite mineralisation at all deposits occur along micro-shears, and
in brecciated / laminar quartz veinlets within the highly- sheared schist. There are several
controls on mineralisation with apparent NNW, N and NNE trending structures all influencing
gold distribution. S h e a r d o m i n a t e d mineralisation within the top 20-40m of the shear zone

occur deeper in the RSSZ.
Unlike Macraes, the gold mineralisation in the oxide, transition and fresh zones is characterised
by coarse free gold.

information for all Material drill holes:
o easting and northing of the drill hole
collar
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.

Data aggregation
methods
• In reporting Exploration Results, weighting

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
Significant gold intercepts are reported on a continuous basis using 0.25g/t Au and 0.50g/t Au
lower grade cut-offs with a maximum of 4m of internal dilution included. Broad zonation is:
0.10g/t Au cut-off defines the wider low-grade halo of mineralisation, 0.25g/t Au cut-off
represents possible economic mineralisation, with 0.50g/t Au defining high-grade axes /
envelopes.

pXRF analytical results reported for laboratory pulp returns are considered accurate for the
suite of elements analysed.
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 should be a clear
statement to this effect (eg ‘down hole
length, true width not known’).
All intercepts quoted are downhole widths. True widths are estimated perpendicular to
mineralisation boundaries where these limits are known.
Intercepts are associated with a major 20-120m thick low-angle mineralised shear that is
largely perpendicular to the drillhole traces.
Aggregate widths of mineralisation reported up until 2
nd
June 2023 are drillhole intervals
>0.50g/t Au occurring in apparent low angle stacked zones. Subsequent reporting is on a
continuous basis.
There are steeply dipping narrow (1-5m) structures deeper in the footwall and the
appropriateness of the current drillhole orientation will become evident and modified as
additional drill results dictate.
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.
All significant intercepts have been reported.
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.
All significant intercepts have been reported.
