Ternera Mineral Resource increased by +66% to 1.1Moz @ 1.12g/t Au

Highlights

  • Ternera Mineral Resource Estimate ( MRE ) increases to 1.1Moz at 1.12g/t Au at a 0.30g/t Au cut-off contained within a USD1,800/oz gold price optimised pit shell .

  • Successful infill and extensional drilling programs completed since July 2021 have:

  • Increased total ounces by +66% to 1.1Moz;

  • Increased Mineral Resource gold grade by +36% to 1.12g/t Au;

  • Increased Indicated Resources by +570% to 503koz at 1.18 g/t Au; and

  • 46% of the MRE classified as Indicated

  • Multiple, continuous, higher-grade gold zones have been defined, resulting in a Mineral Resource of 715koz’s at 2.31g/t using a 1g/t Au cut-off, demonstrating the potential of Ternera being suited to high-grade open pit mining scenarios.

  • Gold mineralisation remains open in all directions and further drilling is planned to continue Resource expansion and test potential Ternera repeats.

  • Highly effective drilling campaign resulting in low discovery cost of <AUD21/oz.

  • Emerging Gold District – Potential Ternera repeats currently being delineated for drilling.

Tesoro Gold Limited ( Tesoro or the Company ) (ASX:TSO, OTCQB:TSORF) is pleased to report a significant Mineral Resource Estimate (MRE) update for the Ternera Gold Deposit (Ternera) at the Company’s El Zorro Gold Project (El Zorro), in Chile.

Table 2 – El Zorro Gold Project, Ternera Gold Deposit updated Mineral Resource Estimate reported at various cut offs unconstrained classified resource to the 200mRL.

Tesoro Managing Director, Zeff Reeves commented:

“This is a significant milestone for Tesoro and the El Zorro Gold Project. This MRE confirms the quality of the Ternera Gold Deposit, and the exceptional work completed by our team in delivering such a significant update in a short period of time. This MRE highlights the higher-grade portions of the Deposit that we have consistently intersected during recent drilling, with the high-grade zones now being reflected in the significant grade increase we see in the updated MRE.”

“Tesoro is in an enviable position with a now plus 1Moz and growing, robust, open pittable gold deposit within what we believe to be a significant new gold district in Chile, providing exceptional potential to find Ternera repeats on the property.”

Ternera MRE Update

A total of ≈55,000m of additional drill information (155 drillholes) from the previous reported MRE (see ASX Announcement on 28 July 2021) were utilised in this MRE update for the Ternera Gold Deposit.

This drilling was completed between July 2021 and April 2022 with results consistently returning wide, high-grade gold intercepts. Drilling focussed on expanding the Ternera gold MRE as well as increasing the classification of the MRE. A detailed geological reinterpretation and 3D modelling program of the Ternera Gold Deposit was undertaken, resulting in a substantial improvement in gold grade and continuity throughout the deposit. The new geological modelling was greatly enhanced by additional data acquired from infill diamond drilling which has resulted in a substantial increase in the Indicated gold Resource at Ternera (Table 1). The Ternera MRE now contains 503koz classified as Indicated, representing 46% of the total resource.

Delineation of the updated MRE has been completed in a capital efficient manner with a low discovery cost of <A$21/oz, well below the global average of U$45/oz for greenfields discoveries.

ASX Announcement 23 May 2022

About the Mineral Resource Estimate

The revised MRE as at the 23 May 2022 is summarised in Table 1 above.

The Resource has been independently estimated by Mr Lynn Widenbar, a consultant to the Company (see Competent Person Statement) who is a highly credentialled and experienced resource consultant having completed MRE’s for companies including Saracen Mineral Holdings Limited (ASX:NST), Calidus Resources Ltd (ASX:CAI) and Aurelia Metals Ltd (ASX:AMI)

The estimate has been produced by 3D modelling of the host lithology and mineralised fault systems, interpreted to control gold deposition within the Ternera Gold Deposit. The 3D geological framework was utilised to produce a block model grade estimation using Ordinary Kriging (OK).

A full summary of the resource methodology and validation is included below and in Appendix 1. Ternera MRE resources have been classified as Indicated and Inferred based on current drill spacing, and drilling has been verified using the Company’s QAQC program which is to normal industry standards.

ASX Announcement 23 May 2022

Growth Plan

The updated Ternera MRE is the result of a highly successful exploration and drilling campaign following the announcement of the Ternera maiden MRE in July 2021.

The drilling campaign added an additional 155 drill holes and ≈55,000m with results having been previously released to the ASX (Appendix 3). Data from the drilling has highlighted multiple areas within the Ternera Gold Deposit which remain unclassified, and the Company expects additional drilling has the potential to convert these areas to classified Mineral Resources.

Tesoro has also identified significant extensions to the Ternera Deposit, both along strike (north and south) and high-grade zones at depth (Figure 4). These areas represent immediate targets for further resource expansion at Ternera and the Company intends to complete further drilling to continue to increase Mineral Resources.

Furthermore, the Company has recently discovered multiple new targets analogous to Ternera to the north-northwest (Figure 5 - ASX announcement, 19 April 2022). Work is currently being completed to define drill targets at these highly prospective targets, with drilling aiming to commence in the next two months.

The Company is well advanced is assessing the production potential of the El Zorro Gold Project, including the evaluation of open pit mining at Ternera and will provide an update of progress in due course.

Ternera Mineral Resource Estimate Summary

The following is a summary of material information used to estimate the Mineral Resource, as required by Listing Rule 5.8.1 and JORC 2012 Reporting Guidelines. Details of historic drill results and Tesoro’s exploration drilling at Ternera including all collar tables and all significant intersections that have been previously released to the market are listed in the announcements presented in the attached Appendices.

Mineral Tenement and Land Tenure Status

The Ternera Gold Deposit occurs within Tesoro’s El Zorro Gold Project (El Zorro or The Project) which covers a total concession holding area of approximately 570km[2] , located approximately 130km north of Copiapo City, in Region III (Atacama) in northern Chile. The Ternera Deposit is 13km inland from the Pacific Ocean, 57 km by road from the port of Caldera and is well supported by existing road, power, and water infrastructure. A full list of the El Zorro Concessions is presented in Appendix 2.

Tesoro’s 95% owned Chilean subsidiary, Tesoro Mining Chile Ltda, currently owns 85% of the El Zorro Gold Project within a fully diluting joint venture structure.

Figure 6 - El Zorro Gold Project Location Map, showing operating mines in the region and supporting infrastructure.

Geology

The Project is located within the Coastal Cordillera of Chile. At Ternera, gold mineralisation is predominately hosted within numerous intermediate intrusions and associated quartz and sulphide veins, veinlets, and alteration within faulted and strongly altered tonalitic intrusions (El Zorro Tonalite or EZT). The EZT intrusions have intruded Permian aged basement sedimentary sequences. Gold mineralisation at Ternera has been classified as an Intrusive Related Gold System (IRGS) and Tesoro has discovered additional gold targets in the El Zorro District which exhibit similar styles of gold mineralisation.

Gold mineralisation is interpreted to be related to regional scale north-south striking fault zones and associated local north-west striking strike slip faults. Mineralisation is interpreted to occur as discontinuous shoots, controlled by a combination of the intersection of the structures with the

preferred host rock tonalite, and locally developed intersections of fracture populations that developed during strike-slip deformation.

Drilling Techniques and Hole Spacing

Drilling completed at the El Zorro Project and results used to support the MRE includes 300 diamond core (DDH) holes for a total of 100,235m (Figure 7). All diamond holes are drilled from surface with most holes drilled towards the south-west with a dip of 60 degrees. Earlier holes were drilled in various orientations to define the main mineralised trends. Drilling used a HQ (~63.5 mm diameter) drill size. Drill core was collected from a core barrel and placed in appropriately marked core trays. Down hole core run depths were measured and marked with core blocks, and orientation marks were routinely placed onto the core. Core was measured for core loss and core photography and geological and geotechnical logging completed .

ASX Announcement 23 May 2022

Sampling

Sample lengths were determined by geological and significant mineralisation boundaries with a maximum sample length of 1 metre. Core was cut in half longitudinally with an electric core saw. Core was cut such that the orientation line remained in the core tray, and the same half of the core was collected for sampling. Quarter core was submitted to ALS Santiago for chemical analysis using industry standard sample preparation and analytical techniques.

Certified Reference Materials (CRM) at a rate of 1 in 20, and analytical blanks (1:50) were used as part of the QAQC procedures. Field duplicates were generated from coarse reject material from the laboratory and targeted mineralised zones at a rate of 1 in 20.

Sample Analysis

All DDH samples were dispatched to ALS Copiapo Chile for sample preparation. Sample preparation included whole sample crushing to 70% less than 2mm, Boyd rotary slitting to generate a 1 kg sub-sample, and pulverising to achieve better than 85% passing 75 microns (ALS code PREP31B). Sample pulps were dispatched to ALS Santiago Chile for analysis using 50 g fire assay with atomic adsorption finish (ALS code Au-AA26). This method is considered a total analysis.

Estimation Methodology

3-dimensional (3D) modelling of the geology was carried out to generate domains for further analysis and resource estimation.

Statistical analysis was based on these 3D tonalite and fault domains, to determine the capping (top cuts) to be applied to the gold assay data prior to resource estimation. The top cuts varied by domain from 10 to 30 g/t Au. Analysis of density data was also carried out to determine parameters for density estimation. Variography was carried out on gold and density to generate the parameters required for estimation.

Estimation of gold grade and density used an Ordinary Kriging (OK) estimation methodology, with an initial estimation generating mineralised and unmineralised envelopes. A second pass of kriging then used these sub-domains within the major tonalite and fault domains to produce final estimates of gold grade and density .

A dynamic search technique was used in the estimation of the tonalites, which allows the search strategy to follow the local variations in dip and strike of the mineralisation. In the fault domains between the tonalite intrusions a vertical, north-search was used. A three-pass search strategy was used, with search radii of 20m, 35m and 50m respectively.

Resource Classification

Resource classification is based on drill spacing and the average distance to, and the number of samples and drill holes used in the estimation of each block. Indicated material is generally assigned to blocks within areas of ~20m to 25m drill spacing, while Inferred material has up to ~40m to 50m drill spacing. Blocks with more widely spaced drill spacing are estimated but are not classified as part of the Mineral Resource.

Mining and Metallurgy

Development of this Mineral Resource adopts mining standard equipment and methods using a conventional truck and hydraulic excavator and open pit mining at an appropriate bench height.

Mineral Resource Statement

The mineralised material that has been interpreted to have “reasonable prospects of eventual economic extraction” by open pit mining methods was defined as mineralised material that has a cut-off grade above 0.30 g/t within an optimised pit shell. The assumptions used in to model the optimised open pit shell are presented in the table below.

Section 1: Sampling Techniques and Data

Criteria JORC Code explanation Commentary
Sampling
techniques
Nature and quality of sampling (e.g. cut
channels, random chips, or specific specialised
industry standard measurement tools
appropriate to the minerals under
investigation, such as downhole gamma
sondes, or handheld XRF instruments, etc.).
These examples should not be taken as
limiting the broad meaning of sampling.
Tesoro has completed 300 diamond drill holes for 100,235m
in 2017, 2018, 2020, 2021 and 2022 (ZDDH0001 to
ZDDH00296) in the area of the MRE. Diamond drill holes were
drilled with HQ. Sampling was half core at geologically defined
and significant mineralisation boundaries.
The CP considers the sampling methodologies to be
appropriate for this style of mineralisation.
Include reference to measures taken to ensure
sample representivity and the appropriate
calibration of any measurement tools or
systems used.
Tesoro Diamond drill holes were drilled with HQ. Sampling was
half core at geological and significant mineralisation
boundaries. The CP consider this appropriate for the style of
mineralisation.
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 (e.g. ‘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 (e.g. submarine nodules)
may warrant disclosure of detailed information.
Diamond drilling was used to obtain ½ core samples of various
lengths (minimum 0.25m), from which 1kg of material was
pulverised passing 200 mesh to produce a 50g charge for fire
assay fusion with a gravimetric finish. Multielement assays
were completed by 4-acid digest with a 2.5g charge. The CP
consider these appropriate assay techniques.
Drilling techniques Drill type (e.g. core, reverse circulation, open-
hole hammer, rotary air blast, auger, Bangka,
sonic, etc.) and details (e.g. 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.).
Tesoro has completed 300 diamond drill holes for 100,235m
in the MRE area. Diamond drill holes were drilled with HQ.
Sampling was half core at geological and significant
mineralisation boundaries. Standard tube was used.
Drill sample
recovery
Method of recording and assessing core and
chip sample recoveries and results assessed.
Core recovery was estimated using the drillers recorded depth
marks against the length of the core recovered. Reviewing the
core photos, there are occasional shears/faults where core is
broken. There is however no significant core loss.
Measures taken to maximise sample recovery
and ensure representative nature of the
samples.
A single tube system was employed and in general core
recovery good.
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.
There appears to be no potential sample bias as there was no
regular loss of core.
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.
Geological core logging to a resolution of 25 cm was
undertaken with a record kept of, inter alia, colour, lithology,
weathering, grain size, mineralisation, alteration, geotechnical
characteristics etc. Diamond core is stored at the Company’s
warehouse.
Tesoro consider the data to be of an appropriate level of detail
to support a future resource estimation.
Whether logging is qualitative or quantitative in
nature. Core (or costean, channel, etc.)
photography.
Logging of diamond core was qualitative and diamond core was
photographed.
The total length and percentage of the relevant
intersections logged.
All drilled intervals are logged and recorded.
Subsampling
techniques and
sample
preparation
If core, whether cut or sawn and whether
quarter, half or all core taken.
Drill core was cut, and half core was collected for analysis
If non-core, whether riffled, tube sampled,
rotary split, etc. and whether sampled wet or
dry.
Tesoro has not completed any percussion drilling.
For all sample types, the nature, quality and
appropriateness of the sample preparation

Criteria JORC Code explanation Commentary
The sample preparation of crushing half core at the lab to mm
size prior to splitting off a 50g charge (either by cone/quarter
or riffle) for pulverisation provides an appropriate and
representative sample for analysis.
Quality control procedures adopted for all
subsampling stages to maximise representivity
of samples.
Half core was collected for the entirety of the Tesoro drilling, as
such there was consistency throughout the drilling. Core was
logged by a qualified geoscientist. Each subsample is
considered to be representative of the interval.
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.
Sampling of half core is representative of the in-situ material.
There are field duplicate samples collected from the diamond
core with irregular results. Field drill core duplicates are
irregular by nature and it has been recommended by Tesoro’s
consultants to use coarse reject material to monitor the
samplepreparation.
Whether sample sizes are appropriate to the
grain size of the material being sampled.
Sample sizes collected were considered appropriate to
reasonably represent the material being tested.
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.
Assays reported in this report were undertaken at the
accredited laboratory of ALS Santiago, which is fully certified.
Core samples of various lengths were assayed (minimum
0.25m) from which 1kg of material was pulverized passing 200
mesh to produce a 50 g charge for fire assay fusion with
gravimetric finish. Multielement assays were completed by 4-
acid digest with a 2.5 g charge.
All techniques are appropriate for the element being
determined.
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.
Standard chemical analyses were used for grade
determination. There was no reliance on determination of
analysis by geophysical tools.

Geology Deposit type, geological setting and style of
mineralisation.
The mineralisation model is considered to be an intrusive related
gold deposit. The key characteristics that are consistent with this
style deposit include:
• Low sulphide content, (typically <5%); reduced ore mineral
assemblage that typically comprises pyrite and lacks primary
magnetite or hematite
• Mineralisation occurs as sheeted vein deposits or stockwork
assemblages and often combine gold with variably elevated Bi,
W, As, Mo, Te, and/or Sb but low concentrations of base metals
as seen in the initial four holes by Tesoro at El Zorro
• Restricted and commonly weak proximal hydrothermal
alteration
• Intrusions of intermediate to felsic composition.
Drillhole

A summary of all information material to the
understanding of the exploration results
including a tabulation of the following
information for all Material drillholes:
o easting and northing of the drillhole collar
o elevation or RL (Reduced Level – elevation

collar
o dip and azimuth of the hole
o downhole length and interception depth
o hole length.

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.
Exploration results are not being reported.
The assumptions used for any reporting of
metal equivalent values should be clearly
stated.
No metal equivalents are 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 drillhole angle is known, its
nature should be reported.
The mineralisation forms sub-vertical sheeted veins and individual
veins and may form plunging zones within the mineralised
structures. Drilling by Tesoro has been undertaken to test these
orientations.
If it is not known and only the downhole
lengths are reported, there should be a clear
statement to this effect (e.g. ‘downhole
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 drillhole collar
locations and appropriate sectional views.
Relevant maps and diagrams are included in the body of the
report.
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.
Exploration results are not being reported..

Database
integrity
Measures taken to ensure that data has not
been corrupted by, for example, transcription
or keying errors, between its initial collection
and its use for Mineral Resource estimation
purposes.
Data validation procedures used.
The Tesoro drill hole database is managed and validated by Cube
Consulting. Drill core is logged with digital templates and codes
are automatically validated during entry. Assay data is provided
digitally by the laboratory and automatically uploaded to the
database.
The data is stored in an SQL database system and exported to an
MS Access database when required.
Drill hole data was provided to Widenbar in the Access database
format (file: Surpac ElZorro_Current_20220428.mdb) and
exported to Excel spreadsheet format prior to import into
Micromine software.
All drill hole data was validated in Micromine after import,
including:

Checks for duplicate collars

Checks for missing samples

Checks for down hole from-to interval consistency

Checks for overlapping samples

Checks for samples beyond hole depth
Site visits Comment on any site visits undertaken by the
Competent Person and the outcome of those
visits.
If no site visits have been undertaken
indicate why this is the case.
Due to Covid-19 and related travel restrictions, the Competent
Person has not yet made a site visit; however, communications
with Tesoro technical personnel has been completed.
The site has been visited multiple times by the Competent Person
for Exploration Results, and many detailed discussions have
taken place to confirm to the MRE CP the procedures in place
relevant to drilling, sampling, logging and general drill hole data
collectionprocesses.
Geological
interpretation
Confidence in (or conversely, the uncertainty
of) the geological interpretation of the
mineral deposit.
Nature of the data used and of any
assumptions made.
The effect, if any, of alternative
interpretations on Mineral Resource
estimation.
The use of geology in guiding and controlling
Mineral Resource estimation.
The factors affecting continuity both of grade
_andgeology. _
There is good confidence in the differentiation of the modelled
rock types and in the continuity of the various tonalite domains.
Both drilling and mapping have been utilised in arriving at the
interpretation and new drilling results have generally confirmed
existing models.
3D geological models have been constructed for the tonalite
domains to control interpolation of gold grades.
Dimensions The extent and variability of the Mineral
Resource expressed as length (along strike or
otherwise), plan width, and depth below
surface to the upper and lower limits of the
Mineral Resource.
The mineralisation extends over a strike length of 1,100 km and a
width of 600m.
Mineralisation extends up to 600m below the topographic
surface.
Estimation and
modelling
techniques
The nature and appropriateness of the
estimation technique(s) applied and key
assumptions, including treatment of extreme
grade values, domaining, interpolation
parameters and maximum distance of
extrapolation from data points. If a computer
assisted estimation method was chosen
include a description of computer software
and parameters used.
The availability of check estimates, previous
estimates and/or mine production records
and whether the Mineral Resource estimate
takes appropriate account of such data.
The assumptions made regarding recovery of
by-products.
Estimation of deleterious elements or other
non-grade variables of economic significance
(eg sulphur for acid mine drainage
characterisation).
In the case of block model interpolation, the
block size in relation to the average sample
spacing and the search employed.
A geological block model was constructed using Micromine 2022
software. The block size was 10m E x 10m N x 10m RL with sub-
blocking to 1.25 x 1 .25 x 1.25 m to honour topographic and
geological boundaries.
A first pass estimation of gold grade constrained by the tonalite
and fault domains and using 1m composites by an Ordinary
Kriging methodology was used to generate mineralised and waste
sub-domains.
Gold grades and density were then interpolated into these sub-
domains. Only diamond drill holes were used in grade estimation.
In tonalite domains the first pass search ellipse was 20x20x8m,
with a second pass of 35x35x10m and a third pass of
50x50x12m.
In fault the first pass search ellipse was 10x5x15m, with a second
pass of 25x10x25m and a third pass of 50x12x50m.
Density estimation used similar parameters, except for pass 3,
which was expanded to 150x30x50 due to the sparser nature of
density samples in some areas.
The minimum number of samples is 8 in pass 1, 6 in pass 2 and
4 in pass 3. Maximum number of samples is 20 in all passes.
Minimum number of holes is 2 in all passes. Minimum number of
samples per hole is 2 in all passes. Maximum number of samples
per hole is 6 in allpasses.

The mineralised envelope within each tonalite or fault domain is
used as a hard boundary for estimation; no composite data from
outside of the envelope is used to inform the grade of blocks
within the mineralised envelope. Blocks outside the mineralised
envelope are similarly modelled.
A top cut for Au was determined from review of log probability
plots. It varies between 10 and 30 g/t depending on domain.
The estimation process was validated by comparing global block
grades with the average composite grades, visual checks
comparing block grades with raw assay data and swathe plots. All
methods showed good correlation between drill data and block
model.
Moisture Whether the tonnages are estimated on a dry
basis or with natural moisture, and the
method of determination of the moisture
content.
All tonnages are estimated on a dry basis and moisture content is
not considered in the resource estimate.
Cut-off
parameters
The basis of the adopted cut-off grade(s) or
quality parameters applied.
The resource has been reported at a 0.3 g/t Au cutoff. This is
based on the costs and recoveries used in generating the optimal
pit shell for a US$ 1,800 per ounce gold price. Details of these
parameters are included in the bodyof the report.
Mining factors
or assumptions
Assumptions made regarding possible mining
methods, minimum mining dimensions and
internal (or, if applicable, external) mining
dilution. It is always necessary as part of the
process of determining reasonable prospects
for eventual economic extraction to consider
potential mining methods, but the
assumptions made regarding mining
methods and parameters when estimating
Mineral Resources may not always be
rigorous. Where this is the case, this should
be reported with an explanation of the basis
of the mining assumptions made.
It is assumed that mining will be by open pit methods. The
resource is reported in-situ with no dilution or mining recovery
factors applied.
Metallurgical
factors or
assumptions
The basis for assumptions or predictions
regarding metallurgical amenability. It is
always necessary as part of the process of
determining reasonable prospects for
eventual economic extraction to consider
potential metallurgical methods, but the
assumptions regarding metallurgical
treatment processes and parameters made
when reporting Mineral Resources may not
always be rigorous. Where this is the case,
this should be reported with an explanation
of the basis of the metallurgical assumptions
made.
Preliminary metallurgical test work was completed on core
samples from the project area (ASX Release 9 June 2020). This
reported mineralised material is free milling with gold recoveries
up to 99%. Additionally, the material was amenable to gravity
concentration with 55% to 75% of the gold reporting to the gravity
concentration. Initial test work indicates the potential to use a
gold processing circuit consisting of conventional gravity
concentration with CIL.
More recent, detailed metallurgical test work results (ASX Release
10 December 2021) indicate achievable gravity recovery of 45%
and overall recovery of 94.5% at a 150 µm grind size and up to
98% at finer grind sizes.
As with the Phase 1 test work, the Phase 2 leach test work
demonstrated rapid leach times with the majority of tests
achieving total gold extraction in excess of 90% within 8 hours.
These results will be used to set the process design criteria for
Tenera confirming the potential for ore processing using a simple,
conventional crush, grind, gravity recovery and leach flowsheet
achievinghigh recoveries.
Environmental
factors or
assumptions
Assumptions made regarding possible waste
and process residue disposal options. It is
always necessary as part of the process of
determining reasonable prospects for
eventual economic extraction to consider the
potential environmental impacts of the
mining and processing operation. While at
this stage the determination of potential
environmental impacts, particularly for a
greenfields project, may not always be well
advanced, the status of early consideration of
these potential environmental impacts
should be reported. Where these aspects
have not been considered this should be
reported with an explanation of the
environmental assumptions made.
Environmental considerations have not been factored into this
Mineral Resource Estimate.
Bulk density Whether assumed or determined. If
assumed, the basis for the assumptions. If

Classification The basis for the classification of the Mineral
Resources into varying confidence
categories.

in tonnage/grade estimations, reliability of
input data, confidence in continuity of
geology and metal values, quality, quantity

Whether the result appropriately reflects the
Competent Person’s view of the deposit.
The Mineral Resource has been classified in the Indicated (46%)
and Inferred (54%) categories, in accordance with the 2012
Australasian Code for Reporting of Mineral Resources and Ore
Reserves (JORC Code).
A range of criteria has been considered in determining this
classification including:

Geological continuity;

Data quality;

Drill hole spacing;

Modelling technique;

Estimation properties including search strategy,
number of informing data and average distance of data
from blocks.
Resource classification is based on drill spacing and the average
distance to, and the number of samples and drill holes used in
the estimation of each block.
Indicated material is generally assigned to blocks within areas of
~20m to 25m drill spacing, while Inferred material has up to
~40m to 50m drill spacing. Blocks with more widely spaced drill
spacing are estimated but are not classified as part of the Mineral
Resource.
The mineral resource estimate appropriately reflects the
Competent Person’s views of the deposit.
Audits or
reviews
The results of any audits or reviews of
Mineral Resource estimates.
The current model has not been audited by an independent third
party.
Discussion of
relative
accuracy/
confidence
Where appropriate a statement of the relative
accuracy and confidence level in the Mineral
Resource estimate using an approach or
procedure deemed appropriate by the
Competent Person. For example, the
application of statistical or geostatistical
procedures to quantify the relative accuracy
of the resource within stated confidence
limits, or, if such an approach is not deemed
appropriate, a qualitative discussion of the
factors that could affect the relative accuracy
and confidence of the estimate.
The statement should specify whether it
relates to global or local estimates, and, if
local, state the relevant tonnages, which
should be relevant to technical and economic
evaluation. Documentation should include
assumptions made and the procedures used.
These statements of relative accuracy and
confidence of the estimate should be
compared with production data, where
available.
The resource estimate is deemed to be an accurate reflection of
both the geological interpretation and tenor of mineralisation
within the deposit.
The mineral resource statement relates to a global tonnage and
grade estimate. Grade estimates have been made for each block
in the block model.
No production data is available.
