ASX Announcement 28 July 2021

Tesoro Managing Director, Zeff Reeves commented:

“Tesoro is pleased to be able to deliver a significant, but incremental MRE at the El Zorro Gold Project within only 18 months of its re-quotation on ASX. This is an amazing achievement during globally challenging times, full credit to our professional and diligent team in Chile who have not missed a beat in executing the work required to deliver this MRE.

We see this as just the start for El Zorro, we are committed to significantly increasing this Mineral Resource via our ongoing drilling programs with the deposit at Ternera open in all directions. We are also seeing significant potential for additional resources to be added over the coming months from other targets, particularly the adjoining Ternera East and Drone Hill targets, which is not included in the MRE. Project studies including mining, metallurgy, environmental, hydrogeology and infrastructure are all underway to be able to define the project and assess the potential of developing a gold mine at El Zorro”.

Ternera Maiden Mineral Resource

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 550km[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.

ASX Announcement 28 July 2021

Tesoro commenced work on the project in 2017 and has subsequently drilled 201 diamond drill holes, at El Zorro and defined the Ternera Gold Deposit. The Maiden MRE is based on 148 diamond holes (46,937 m of drilling). In total Tesoro has drilled 203 holes for 61,763 m of drilling at Ternera with diamond drill programs ongoing throughout 2021.

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) which is a new style of gold mineralisation, previously undescribed in Chile. Tesoro has discovered additional gold targets in the El Zorro District which exhibit similar styles of gold mineralisation.

ASX Announcement 28 July 2021

Mineralisation within the reported MRE has been classified according to JORC 2012 code and has been reported with an optimised pit shell.

A majority of the MRE area has been drilled on a 50m x 50m drill spacing and is classified as inferred resources. A small portion in the Central Ternera area has been drilled at a sufficient density to be classified as Indicated Resources (Figure 3).

Within the Ternera Mineral Resource envelope, higher grade gold mineralisation is associated with distinct north-south faults which are both strike and dip extensive. These fault zones have formed a number of higher-grade portions which remain open down dip and along strike (Figure 4).

The Ternera Gold Deposit remains open in all directions, drilling continues to both improve the reported resource categories, expand and add additional gold resources.

The company has now drilled >200 diamond drill holes at Ternera, with only 148 holes included in the MRE, there is significant scope for Tesoro to increase the Resource inventory at El Zorro during 2021.

Exploration Potential

Since February 2020 Tesoro has been primarily focussed on defining and expanding a Mineral Resource at the Ternera Deposit. However preliminary drilling was also completed which confirms gold mineralisation outside of the Ternera Deposit at the Ternera East, Drone Hill and Toro Gordo targets, all of which offer opportunities to increase gold Resources across the project area. A large body of the prospective EZT has also been mapped at the Toro Blanco target to the north of Ternera.

ASX Announcement 28 July 2021

The Company has 6 diamond drill rigs on site at El Zorro drilling 24/7.

Drilling will be focussed on:

Define Measured, expand Indicated and Inferred Resources at Ternera;
Delineation of gold resources at Ternera East and Toro Gordo;
Further drill testing at Drone Hill; and
Initial drill testing at Toro Blanco.

Significant exploration potential exists throughout the El Zorro concessions with identification of the EZT host rocks in the wider El Zorro area. Exploration will continue throughout 2021 to assess and drill test new targets as they are identified.

TERNERA MINERAL RESOURCE ESTIMATE

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 550km2, 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 3.

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.

Geology

In the El Zorro Project, the main mineralised intrusions are underlain by a Devonian age sedimentary rock sequence consisting of interbedded siltstone, volcaniclastics, and minor quartzite, all of which has been variably metamorphosed and folded.

In the El Zorro project area, both the sediments have been intruded by multiple mineralised tonalite to diorite intrusions interpreted as a possible late stage differentiate of a larger granodiorite body, and have been emplaced as dykes and sills. The granodiorite intrusion has significantly thermally metamorphosed the sediments within several hundred metres of the contact resulting in highly resistant phyllite, dark fine grained hornfels and quartzite. The phyllite is a very fine grained, foliated, black, dense rock.

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 used to support the MRE includes 148 diamond core (DDH) holes for a total of 46,937 m (Figure 2). All diamond holes are drilled from surface with most holes drilled towards the southwest 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.

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.

ASX Announcement 28 July 2021

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 PREP-31B). 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

The geological interpretation utilised lithological logging data, and assay data to guide and control the Mineral Resource estimation. Leapfrog™ implicit modelling software was utilised to generate three-dimensional wireframes of the applicable lithology and fault zone horizons. Estimation domains were based on interactions between the north-south striking fault domains and the intersecting tonalite lithology domains.

Drill hole sample data was flagged using domain codes generated from three-dimensional mineralisation domains. Sample data was composited to one-metre downhole lengths using a best fit-method. No residuals were generated. Statistical analysis was carried out on data from all estimated domains, with hard boundary techniques employed within each estimation domain.

Analysis of the composite data indicated the presence of outlier values indicating grade capping was required for selected domains. Capped values were generally selected above the 99[th] percentile. Additionally, distance restrictions on samples with elevated grades were applied whereby the composite grade is capped at a specified threshold outside of a nominated influence distance, typically 20 m.

Grade estimates were completed for gold (Au g/t) and density (g/cm[3] ). The grade estimation process was completed using Maptek Vulcan software using Ordinary Kriging (OK) together with dynamic anisotropy to guide the grade interpolation parallel to the domain boundaries. For estimation domains with insufficient sample data a variogram model from a comparable domain was assigned.

Interpolation parameters were derived using standard exploratory data analysis techniques of statistical and continuity analysis. Appropriate interpolation strategies were developed on a domain basis using kriging neighbourhood analysis (KNA) with a minimum number of 8 composites and a maximum number of 20 composites. Blocks were estimated in a two-pass strategy with first pass maximum search distances of 50 metres. The second pass search distance was increased to between 100 m to 180 m depending on domain and modelled variogram continuity. An image showing the estimated grades across the model is presented in Error! Reference source not found. .

Figure 3 - Oblique view looking north west showing Indicated and Inferred blocks above 0.3 g/t Au

The model has a block size of 20 m (X) by 20 m (Y) by 5 m (Z) within the moderately dipping tonalite domains, and 5 m (X) by 20 m (Y) by 20 m (Z) within the steeply dipping north-south striking fault domains. Sub-celling of 2.5 m (X) by 2.5 m (Y) by 1.25m (Z) was applied across the block model to aid in suitable volume definition. Grades were estimated into the parent cells.

The block model was validated using a combination of visual and statistical techniques including global statistics comparisons, and trend plots, and grade-tonnage assessments.

Resource Classification

A range of criteria was considered by Cube when addressing the suitability of the classification boundaries. These criteria include:

Geological continuity and volume;
Drill spacing and drill data quality;
Modelling technique; and
Estimation properties, including search strategy, number of informing composites, average distance of composites from blocks and kriging quality parameters.

Blocks have been classified in both the Indicated (11%) and Inferred (89%) categories, primarily based on geological interpretation confidence and drill data spacing in combination with other model estimate quality parameters.

The Indicated Resource is constrained to the central portion of the project area with the greatest drill density and restricted to the main tonalite lithology unit and associated fault domains.

Cut-off Grade

The Mineral Resource has been reported above a 0.30 g/t Au cut-off. Selection of the cut-off has considered results of metallurgical testing (ASX release 9 June 2020). The applied cut-off has been reviewed against that reported from peer projects with similar mineralisation styles and proposed processing options and is considered comparable.

Reporting of Mineral Resources have been assessed against a resource limiting optimisation shell using appropriate cost, metallurgical recovery, and price assumptions. Material within the optimised pit shell has, in the opinion of the Competent Person, met the conditions for reporting of a Mineral Resource with reasonable prospects of eventual economic extraction.

Mining and Metallurgy

Development of this Mineral Resource assumes mining using standard equipment and methods. The assumed mining method is conventional truck and shovel, 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.

APPENDIX 4 – JORC TABLES

JORC Table 1

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 203 diamond drill holes for 61,673m in 2017, 2018, 2020 and 2021 (ZDDH0001 to ZDDH00203). Diamond drill holes were drilled with HQ. Sampling was half core at geologically defined and significant mineralisation boundaries. Tesoro 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. Tesoro 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. Tesoro 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 203 diamond drill holes for 61,673m.. 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 technique.	Collection of half core ensured the nature, quality and appropriateness of the collected sample. The sample preparation of crushing half core at the lab to mm sizeprior to splittingoff a 50gcharge(either bycone/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.
	• Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established.	QAQC procedures included the insertion of Certified Reference Materials (CRMs) (5%) and blank material (2%), Check samples (5%) and check assaying 5% Cube Consulting Pty Ltd manage the database for Tesoro. The laboratories used have generally demonstrated analytical accuracy at an acceptable level within 95% confidence limits.
Verification of sampling and assaying	• The verification of significant intersections by either independent or alternative company personnel.	A number of independent consulting geoscientists (Cube Consulting, Oliver, and Cooley) external to Tesoro have verified the intersections for holes ZDDH0001 to ZDDH0080. Holes ZDDH0081 onwards have been verified by multiple appropriately qualified Company personnel.
	• The use of twinned holes.	no twinned holes have been completed
	• Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols.	Tesoro drilling is digitally entered and stored following documented core handling protocols. The protocols are considered adequate.
	• Discuss any adjustment to assay data.	No adjustments were made to Tesoro Drilling
Location of data points	• Accuracy and quality of surveys used to locate drillholes (collar and downhole surveys), trenches, mine workings and other locations used in Mineral Resource estimation.	Tesoro drill hole collars have been surveyed accurately using differential GPS for holes ZDDH0001 to ZDDH00080. Holes ZDDH0081 onwards have been surveyed using handheld GPS and will be surveyed using differential GPS once the drill program has concluded.
	• Specification of thegrid system used.	Thegrid system used PSAD56 19S
	• Quality and adequacy of topographic control.	The topography generated from an accurate topographic survey data completed by a registered surveyor and has been used for the current control.
Data spacing and distribution	• Data spacing for reporting of Exploration Results.	Drill hole spacing is variable between 25m and 200m
	• 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.	The spacing of drill holes is variable and satisfactory for reconnaissance level drilling. The holes are not intended to be used for resource estimates at this stage of exploration.
	• Whether sample compositing has been applied.	Sample composites was not employed.
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.	Drill holes were drilled across the interpreted strike of the mineralization
	• If the relationship between the drilling orientation and the orientation of key	Tesoro diamond drilling at various orientations does not reveal anybias regardingthe orientation of the mineralised horizons.

Sample security	• The measures taken to ensure sample security.	Chain of Custody of digital data is managed by the Company. Physical material was stored on site and, when necessary, delivered to the assay laboratory. Thereafter laboratory samples were controlled by the nominated laboratory which to date has been Bureau Veritas and ALS Santiago. All sample collection was controlled by digital sample control file(s) and hardcopyticket books.
Audits or reviews	• The results of any audits or reviews of sampling techniques and data.	No audits have been undertaken.

(Criteria in this section apply to all succeeding sections)

Section 2: Reporting of Exploration Results

(Criteria listed in the preceding section also apply to this section)

Criteria	JORC Code explanation	Commentary
Mineral tenement and land tenure status	• Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings.	Information regarding tenure is included as Appendix 3 to this report. Tesoro Resources Ltd, 95% owned Chilean subsidiary, Tesoro Mining Chile SpA, owns 85% of the El Zorro Gold Project Concessions.
	• The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area.	The Concession is believed to be in good standing with the governing authority and there is no known impediment to operating in the area.
Exploration done by other parties	• Acknowledgment and appraisal of exploration by other parties.	Little historical exploration has been undertaken in either project area. Coeur d’Alene’s Chilean exploration division undertook activities on the Ternera prospect, under an option agreement with theprevious owners between April 1990 and January1993.
Geology	• Deposit type, geological setting and style of mineralisation.	The mineralisation model is to likely to be 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 information	• 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 above sea level in metres) of the drillhole collar `o` dip and azimuth of the hole `o` downhole 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.	Information relating to current drill program presented in this report.
Data aggregation methods	• In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated.	No cutting of grades has been undertaken at this early stage of exploration drilling. Downhole intercepts are calculated using a length weighted averaging method.

	• 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.	Tesoro has completed 190 diamond drill holes for 58,555m in 2017, 2018, 2020 and 2021 (ZDDH0001 to ZDDH00190). Diamond drill holes were drilled with HQ. Sampling was half core at geologically defined and significant mineralisation boundaries. Down hole length weighted average results are calculated using a 0.20g/t Au cut off and a maximum of 5m internal dilution
	• 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’).	Exploration results are reported as downhole widths as the true width is not known with any certainty.
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.	All assay results from drilling are reported. Reporting of visible gold occurrences in drill core is by visual inspection only and final gold content is not known until assay results have been received.
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.	All material exploration data is reported in the body of the report.
Further work	• The nature and scale of planned further work (e.g. tests for lateral extensions or depth extensions or large-scale step-out drilling).	Further work will be focused on drill testing the Ternera mineralisation and additional prospects as defined in the work program. Core will be used for metallurgical testwork and resource modellingisplanned.
	• Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive.	Diagrams have been included in the body of this report.

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.	Logging of drill core is completed into digital logging templates with inbuilt validation and code libraries to avoid incorrect code entries. Logging is completed on 100% of drill core metres. Downhole survey data is collected via gyro tool and exported as text files for direct entry to the database. Assay results are provided in digital text files and imported directly to the database. The data is stored in a SQL database and managed by a third- party administrator, with Access extracts generated as needs for use in interpretation and estimation processes. The SQL database has restricted access and inbuilt referential validation to prevent loading of overlapping or duplicate entries.

		the respective drill core for the majority of drill holes as part of the interpretation process.
Site visits	• Comment on any site visits undertaken by the Competent Person and the outcome of those visits.	The project site has been visited by the Competent Person for Exploration Results who has observed drilling operations, reviewed drill core, and reviewed sampling and QAQC procedures. The Competent Person for Mineral Resources has held discussions with colleagues who completed a “virtual” site visit including live teleconference review of diamond core collection, logging and storage facilities, diamond core cutting and sample selection procedures. Additionally an independent geologist has visited the project area and provided technical details regarding geological and mineralisation controls
	• If no site visits have been undertaken indicate why this is the case.	The project has not been visited by the Competent Person responsible for the reporting of Mineral Resources due to current restrictions on international travel, however all reasonable attempts to validate and verify the assumptions underlying the Mineral Resource have been undertaken.
Geological interpretation	• Confidence in (or conversely, the uncertainty of ) the geological interpretation of the mineral deposit.	Drilling and mapping have confirmed the overall geological model and interpretation, with geological features being predictablyencountered from modelling.
	• Nature of the data used and of any assumptions made.	The overall geological model has been completed using a combination of detailed surface mappingand drill data.
	• The effect, if any, of alternative interpretations on Mineral Resource estimation.	No alternative interpretations have been justified.
	• The use of geology in guiding and controlling Mineral Resource estimation.	Geological 3D models have been constructed of hoist lithologies and controlling structures to build suitable geological domains to control the resource estimation.
	• The factors affecting continuity both of grade and geology.	Grade continuity is affected by uncertainty as to the continuity of the interpreted mineralised structures and host lithologies. In areas with sufficient drill and data density continuity of grade and geology is increased.
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 overall defined Mineral Resource has a strike extent of ~1,000 metres and across strike extent of ~500 metres, up to depths of ~500 metres below natural 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.	Estimates were generated for gold (Au g/t) and density (g/cm3). The grade and density estimation used the Ordinary Kriging (“OK”) technique together with dynamic anisotropy to guide the grade interpolation parallel to the estimation domain boundaries. Interpolation parameters were derived using standard exploratory data analysis techniques of statistical and continuity analysis. Appropriate interpolation strategies were developed on a domain basis using kriging neighbourhood analysis (“KNA”), which included: • Two pass estimation approach with first pass oriented ellipsoidal search radii limited to a maximum of 50 m • Second pass radii ranged from 100m to 180m within the tonalite depending on the estimation domain, and between 120 and 125m within the NS domains; • Minimum number of samples = 8; • Maximum number of samples = 20 The maximum extrapolation distance from the last data points was approximately 60m. Computer software used for the modelling and estimation were: • Leapfrog Geo 2021.1 was used for geological domain modelling. • Supervisor v8.14 was used for geostatistical analysis. • Maptek Vulcan 2021 was used for grade estimation, block modelling and reporting.
	• The availability of check estimates, previous estimates and/or mine production records and whether the Mineral Resource estimate takes appropriate account of such data.	This estimate represents the maiden resource for the project. The results are comparable to a number of internal estimates prepared previously. No commercial mining production has taken place at the project.

	• The assumptions made regarding recovery of by-products.	No by-product recoveries were considered.
	• Estimation of deleterious elements or other non-grade variables of economic significance (eg sulphur for acid mine drainage characterisation).	Other than for density no other non-grade or deleterious elements have been estimated.
	• In the case of block model interpolation, the block size in relation to the average sample spacing and the search employed.	Selection of the block size was based on the geometry of the mineralisation, data density, and the likely degree to which selective mining can be successfully applied to the geologically based domain boundaries. The estimation block model definitions are: • Non-rotated block model with an azimuth of 000ºGN; • OK panel size was set at 20m x 20m x 5m (XYZ) within the moderately dipping tonalite domains, and modified to 5m x 20m x 20m (XYZ) within the steeply dipping NS domains • Sub-block size of 2.5m x 2.5m x 1.25m (XYZ); • The drill spacing varies from ~25m x 25m in the better drilled portions out to 100m x 100m at the margins of the modelled mineralisation.
	• Any assumptions behind modelling of selective mining units.	No assumptions have been made regarding potential selective mining units
	• Any assumptions about correlation between variables.	No correlations were assessed
	• Description of how the geological interpretation was used to control the resource estimates.	Three-dimensional lithological domains were generated for the tonalite units using LeapfrogTMsoftware. Additionally, a series of north-south (NS) extending shear zones were modelled in LeapfrogTMguided by alteration and shearing observed in core photos. The interaction of the tonalite lithological domains and the NS structures was used to generate estimation domains. Drill hole data was coded with respect to the position relative to the tonalites and NS structures and composited to one-metre downhole using the distribute function within Vulcan to minimise the generation of short composites.
	• Discussion of basis for using or not using grade cutting or capping.	An appropriate top cutting strategy based on assessment of the grade distributions and log-probability plots was used to minimise the influence of isolated high-grade outliers with capped values within the tonalite domains ranging from 5 to 13 g/t Au, while in the NS domains capping values ranged from 5 to 30 g/t Au. Additionally distance restrictions for composite values above selected thresholds were applied to limit the influence of local high-grade values. Grade thresholds for the distance restrictions ranged between 2 and 9 g/t Au for the tonalite mineralisation and between 2.5 and 17 g/t Au for the NS domains. Composite values above these thresholds were capped outside of a maximum of 20m.
	• The process of validation, the checking process used, the comparison of model data to drill hole data, and use of reconciliation data if available.	The estimation model was validated using the following techniques: • Visual 3D checking and comparison of informing samples and estimated values; • Global statistical comparisons of raw sample and composite grades to the block grades; • Validation ‘swath’ plots by northing, easting and elevation for each domain, and • Analysis of the grade tonnage distribution.
Moisture	• Whether the tonnages are estimated on a dry basis or with natural moisture, and the method of determination of the moisture content.	Tonnes are estimated on an insitu dry bulk density basis. No moisture content has been assessed or used in estimation.
Cut-off parameters	• The basis of the adopted cut-off grade(s) or quality parameters applied.	Based on pit optimisation parameters
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	The Mineral Resource is being reported assuming extraction via open pit methods using conventional drill and blast and load and haul methods. The cost and related cut-off grade parameters have been developed based on these criteria, with the reported Mineral Resource constrained within a Whittle optimisation shell employing these assumptions, and therefore has demonstrated reasonable prospects for eventual economic extraction.

	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.
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 has been completed on core samples from the project area (ASX Release 9 June 2020). This reports mineralised material is free milling with gold recoveries up to 99%. Additionally, the material is 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.
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.	No Environmental factors have been considered due to early nature of the resource.
Bulk density	• Whether assumed or determined. If assumed, the basis for the assumptions. If determined, the method used, whether wet or dry, the frequency of the measurements, the nature, size and representativeness of the samples.	Bulk density has been determined from 10,421 individual drill core measurements using the water displacement method. Measurements were flagged against the oxidation surface and tonalite domains to generate estimation datasets and were estimated using Ordinary Kriging (OK) in a single pass. Cells un- estimated after the first pass were assigned a domain average density based on the measurements collected. Bulk density measurements varied from 2.0 g/cm3to 3.3 g/cm3 averaging approximately 2.6 g/cm3. Material within the interpreted overburden was assigned a density of 2.0 g/cm3.
	• The bulk density for bulk material must have been measured by methods that adequately account for void spaces (vugs, porosity, etc), moisture and differences between rock and alteration zones within the deposit.	Samples selected for density determination were typically competent, complete intervals of diamond core with no observable vugs or voids. Selection of samples is done for all holes at regular depths throughout the drill hole so is expected to adequately describe the variability of density across the project.
	• Discuss assumptions for bulk density estimates used in the evaluation process of the different materials.	Bulk density is estimated or assigned based on an extensive series of density measurements.
Classification	• The basis for the classification of the Mineral Resources into varying confidence categories.	Classification of the Mineral Resource was completed with consideration of; the confidence in the interpretation boundaries and related mineralisation volumes related to the number, spacing, and orientation of the available drilling; the spatial continuity of respective domains based on variogram analysis; the assessment of key estimation output statistics; and consideration of how well the underlying domain data is reflected in the estimated blocks as assessed by statistics globally and trend plots locally.
	• Whether appropriate account has been taken of all relevant factors (ie relative confidence in tonnage/grade estimations, reliability of input data, confidence in continuity of geology and metal values, quality, quantity and distribution of the data).	The assignment of the respective Mineral Resource categories has considered all relevant factors likely to influence the confidence of the Mineral Resource.
	• Whether the result appropriately reflects the Competent Person’s view of the deposit.	The assigned Mineral Resource classification reflects the Competent Person’s view of the deposit.

Audits or reviews	• The results of any audits or reviews of Mineral Resource estimates.	No audits or review have been completed for the Mineral Resource estimate.
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 relative accuracy of the Mineral Resource estimate is reflected in the reporting of the Mineral Resource as per the guidelines of the 2012 JORC Code and considers the quality of sample data as demonstrated by QAQC results, geological and mineralisation domain confidence, robustness of spatial continuity modelling, and estimation quality output parameters. The Mineral Resource has been classified into Indicated (11%) and Inferred (89%) categories.
	• 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.	The statement relates to the global estimates of tonnes and grades
	• These statements of relative accuracy and confidence of the estimate should be compared with production data, where available.	No production data is available
