SAN JORGE LITHIUM PROJECT UPDATE:

GEOPHYSICS SIGNIFICANTLY EXPANDS BRINE BODY AREA

5 August 2022

Greenwing Resources Ltd ( Greenwing or the Company ) (ASX:GW1) is pleased to report significant progress at the San Jorge Lithium brine project located in Argentina's prolific Lithium Triangle with the completion of a TEM Electrical Geophysical survey.

HIGHLIGHTS

• ♦ A Transient Electromagnetic (TEM) Geophysical survey has significantly expanded the surface area underlain by a highly conductive response, indicative of an expanded brine body

• ♦ Survey confirms that brine continues west from the salar under volcanic flows

• ♦ Ongoing evaluation of multiple Direct Lithium Extraction (DLE) technologies is underway, including fully integrated systems, capable of producing lithium carbonate or lithium hydroxide product

• ♦ Drilling is now planned to commence September/October 2022

• ♦ Drilling will provide bulk brine samples for more detailed pilot test work and assaying.

“We are extremely pleased to have completed the TEM Electrical Geophysical survey and defined the full extent of the brine target at the project. This information will be used to finalise locations for the Phase 1 drilling program, to confirm the range of lithium

concentrations and porosity values in the project. We look forward to commencing the maiden drilling program when the permit is approved by the Mines Department, amid the continued strong outlook for lithium long term.”

• ♦ is located within the Argentina's Lithium Triangle which accounts for a significant portion of the world’s lithium production

• ♦ consists of 15 granted exploration licenses

• ♦ is inclusive of the 2,800-hectare San Francisco Salar, surrounded by gravel slopes

• ♦ is surrounded by major lithium mining and development companies including Allkem, Livent, Gangfeng, Zijin Mining, Rio Tinto, Lithium Americas, Lake Resources and Galan Lithium.

TEM GEOPHYSICAL SURVEY

The Transient Electromagnetic (TEM) Geophysical survey consisted of 10 lines with 128 TEM stations (Figure 3).

The exploration objective of the TEM survey was to map the extent of the brine body, particularly off the salar, and to provide information on the lithologies associated with aquifers in the salar, as well as to define geological structures.

The survey successfully defined the brine body extending beneath lava flows and gravels west of the salar (Figure 3, Line 6), extending up to 2.4 km west of the salar surface. Over the salar the survey defined the presence of brine to depths of 100 to 150m, the maximum resolution of the survey in the highly conductive environment of the salar.

Off the salar the survey has defined extension of the brine body to depths up to 500 metres. The conductivity responses are 1 ohm m or less, which is considered very positive for discovery of brine with potentially economic characteristics for lithium production. The high conductivity zone is surrounded by an extensive zone of 1 to 2 ohm m, less concentrated brine, or brine in more resistive host material.

Figure 4 shows the conductive unit (pink to blue) extending under thin lava flows west of the salar, with some more resistive units that probably represent lava flows (volcanic), also hosting brine. There appear to be more conductive units beneath the resistive (dry) surface lava flow, and these may be volcanic ash, salar sediments, porous or fractured lava flows. The porous units terminate against the volcano to the south of the salar, with brine also extending beneath sporadic volcanic units north of the salar.

MAIDEN DRILLING PROGRAM

The Company is negotiating a contract with an Argentine drilling company, with experience working on salars, for the Company’s maiden drill program at San Jorge. Logistics planning is ongoing, with the aim to begin drilling around the end of the September quarter.

The drilling program is planned around the western and northern margins of the salar, where the TEM survey has confirmed the presence of brine extending away from the salar. Three diamond holes to the bedrock depth (estimated to be around 400m) are planned, with the objective of confirming the lithium concentration and obtaining Initial Information about different types of host lithologies. Positive results from the maiden drill program would justify construction of access roads on to the salar to undertake resource drilling on a regular grid, which is currently planned as a follow up program to the initial program.

DIRECT LITHIUM EXTRACTION (DLE) ANALYSIS

As part of the drilling program well screens would be installed in holes to allow extraction of quantities of brine sufficient for bulk pilot testing, with upwards of 10,000 litres of brine required for testing in each of the different process facilities.

Evaluation of multiple Direct Lithium Extraction (DLE) technologies is currently underway using San Jorge brine, covering the range of different DLE technologies available. This includes fully integrated systems, capable of producing lithium carbonate or lithium hydroxide product. The Company will continue advancing with multiple technology partners prior to the drilling program and extraction of bult samples for pilot scale test work.

PERMITTING

The permitting extension for the TEM survey covered non-intrusive activities. A separate permit is required for drilling activities. The Company is working with authorities on permitting for the drilling program. The high level of mining activity in the area, together with a lack of resourcing within the government departments, has been causing some delays in the granting of permits.

The Company continues to maintain contact with the local community regarding use of local contractors for the project, having already successfully held a meeting with the community presenting the project.

PROJECT LOCATION AND EXPLORATION LICENSES

The project is in Catamarca Province, one of three provinces in the north of Argentina that host globally significant resources of lithium, hosted in brine beneath salars. Extraction of lithium from brine has a lower overall carbon-footprint than from hard rock operations and is a key source of lithium for the electrical revolution, with electrification of transportation and development of large-scale battery storage to accompany renewable energy generation.

JORC Table 1

Section 1 - Sampling Techniques and Data related San Jorge

(Criteria in this section apply to all succeeding sections.)

Criteria	JORC Code explanation	Commentary
Sampling techniques	• Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample 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.	• Geophysics was undertaken on the surface of the salar and surrounding area. The geophysical technique was the Transient Electromagnetic method (TEM) with a 200 x 200 m loop that is moved between stations located 400 m apart on east west lines. The lines are separated by 1000 m in the north-south direction. • TEM has proven to be a highly applicable technique in and around salars, as the method avoids the surface conductivity issues associated with resistivity methods, such as Vertical Electrical Soundings or resistivity profiling. • The TEM method has a lesser penetration on the salar surface, but sees through resistive surface sediments and volcanics to define the extension of brine beneath these units. • Highly conductive zones of <1 ohm m are located beneath the salar surface, continuing to the west under volcanic flow units, surrounded by a zone of 1-2 ohm m resistivity • Survey lines were oriented perpendicular to the elongation of the salar.
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).	• No drilling has been conducted on the project.
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.	• No drilling has been conducted on the project.

Core (or costean, channel, etc) photography. • The total length and percentage of the relevant intersections logged.	• No drilling has been conducted on the project.
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 of the material being sampled.	• No drilling has been conducted on the project.
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 (i.e. lack of bias) and precision have been established.	• This work program relates to electrical geophysics, for which multiple non-unique interpretations are possible. • The receiver was a Geonics Digital PROTEM, with 20 channels. The transmitter was a Geonics EM-37 (2.8 kilo-Watt) and the antenna was a Geonics 3D-3 (200 m2 effective coil area). • With the 200 x 200 m loop, in a centre configuration the transmitted frequencies were 25 Hz & 2.5 Hz. The Normalized Current was 1 A and the Transmit Turn-off Time 100 – 120 useconds. • A frequency of 25 Hz was employed throughout the survey allowing secondary magnetic field decay measurements over a total of 20-time channels. The transmitter and receiver were linked with a reference cable. The transmitter was set to 110 V output producing an average current of 18 amperes, and a turn-off time between 100 and 120 us. • In addition to the 25 Hz frequency, a lower frequency of 2.5 Hz is usually collected. This additional frequencynormally allowsmore

		accurate modelling of the discrete-layer inversions within the modelling package (Interpex IX1Dv3.53). • The receiver was configured to automatically record three samples, each with an integration period of 30 seconds (or higher in noisy areas). Receiver gain was set so that measured response occurred in the unsaturated linear portion of the amplifier’s range but with a relatively large signal present in the late channels.
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.	• This work program relates to electrical geophysics, for which multiple non-unique interpretations are possible. • To evaluate the coherency of the data, a comparison of the graphically displayed decay of the Z-component resistivity vs. time was performed for the three-recorded measurements. If noise was observed, a repeat set of three measurements was recorded and compared. The Z component was measured with the positive field direction vertically upward. X and Y components were also measured, with X coordinate being positive towards north; and Y coordinate being orthogonal toX(positivetowardswest).
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.	• The stations were located with a hand-held GPS. The Project location is in zone 2 of the Argentine Gauss Kruger coordinate system with the Argentine POSGAR 94 datum. • Hand held GPS in this area is typically accurate to within approximately 5 m laterally. • Topographic control is based on information from publicly available SRTM topography, which is considered sufficient for the level of explorationconducted.
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.	• Lines have a 1 km spacing north to south, with stations spaced every 400 m along the east- west lines. • Station spacing is considered sufficient for initial characterisation of the salar.
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.	• The salar deposits that host lithium-bearing brines consist of sub-horizontal beds and lenses of sediments, volcanic ash, and possibly silt, sand and clay, with halite, and gravel, depending on the location within the salar.

Audits or reviews	• The results of any audits or reviews of sampling techniques and data.	• A review of the TEM geophysics has been undertaken. TEM data interpretation will be further integratedwithpassive seismic data.

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. • 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 Greenwing properties consist of 15 properties for a total of 38,000 hectares, of which 2,800 are covering the salar area. The properties are located in the province of Catamarca in northern Argentina at an elevation of approximately 4,000 masl. Greenwing has options to acquire 100% of the properties • The tenements/properties are believed to be in good standing, with payments made to relevant government departments. The company maintains good relationships with the local government and government agencies and communities as partofoperations.
Exploration done by other parties	• Acknowledgment and appraisal of exploration by other parties.	• The properties were subject to brief and inconclusive brine sampling previously, with only 5 brine samples taken along the eastern edge of the salar by the vendor. The sampling completed in October 2021 confirmed comparable results along the eastern side of the salar, with higher results in the centre of the salar.
Geology	• Deposit type, geological setting and style of mineralisation.	• The project is a salar deposit, located in a closed basin in the Andean Mountain range in Northern Argentina. • The sediments within the salar consist of volcanic ash, silt, probably volcanic flows locally, and possibly at deeper levels sand, gravel halite and or clay, which have accumulated in the salar from terrestrial sedimentation from the sides of the basin. Brine hosting dissolved lithium is present in pore spaces. • The geophysics suggests a possible shallow volcanic unit/flow near surface, as a shallow reflector is detected across the survey area. • The sediments are interpreted to be essentially flat lying with unconfined aquifer conditions close to surface and semi-confined to confined conditions at depth • Geology was recorded during previous excavationofshallowpitsforbrine sampling.
Drill hole Information	• A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes:	• No drilling has been conducted on the properties.

Data aggregation methods	• In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. • Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. • The assumptions used for any reporting of metal equivalent values should be clearly stated.	• Individual TEM soundings are recorded at each site and later this information is interpolated into sections, based on data from individual stations.
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’).	• The sediments hosting brine are interpreted to be essentially flat lying. The entire thickness of sediments has potential to host lithium brine, with the water table within approximately 0.3 metre of surface.
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.	• A diagram is provided in the text showing the location of the properties and the geophysics, as well as an example section through the area of geophysics.
Balanced reporting	• Where comprehensive reporting of all Exploration Results is not practicable, representative _reporting of both low and high _	• Data regarding pit sampling for brine was previously provided (02 December 2021).
