MT THIRSTY JOINT VENTURE EXPLORATION UPDATE

• Assays results received for eight drill holes testing 3% of altered ultramafic target horizon at Mt Thirsty

• Assay results pending for a further four holes testing 10% of the altered ultramafic target horizon

• All holes completed to date have intercepted semi-massive and/or heavily disseminated sulphides

• Phase I drill campaign has been updated based on evolving geological model with seven holes to be drilled

• Initial interpretation indicates that secondary controls on mineralisation may influence grade continuity

• Highly anomalous mineralisation intersected in all 8 holes for which assays have been received, including:

• MTRC003D: 27.0 metres @ 0.33g/t 3E[1] , 0.12% Ni & 0.05% Cu from 198.0 metres

• MTDD001D: 18.0 metres @ 0.29g/t 3E, 0.11% Ni & 0.05% Cu from 182.0 metres

• MTRC009D: 10.2 metres @ 0.23g/t 3E, 0.09% Ni & 0.01% Cu from 199.0 metres

• Pegmatite field mapping completed, identifying eight outcropping pegmatites over 1,000 metre strike

• 1,650 metre drill campaign targeting LCT[2] pegmatites to be undertaken on completion of Phase 1 drilling

Greenstone Resources Limited ( ASX:GSR ) ( Greenstone or the Company ) is pleased to provide an update on exploration at the Mt Thirsty Joint Venture ( MTJV ) (Greenstone 50%: Conico Limited 50%), with assays now received for the first eight drill holes, all of which intercepted highly anomalous PGE[3] mineralisation. The current Phase I drill campaign is testing for extensions to the recent palladium-platinum-gold-copper-nickel (PGE) discovery by Galileo Mining Ltd (ASX:GAL) (Galileo) located less than 200 metres from the MTJV’s northern tenement boundary. The MTJV is located 16 kilometres North-Northwest of Norseman, Western Australia.

Phase I drilling activities at the Mt Thirsty Joint venture continue on schedule with twelve holes having now been completed, with all twelve holes having intercepted semi-massive and/or heavily disseminated sulphides within the target horizon. Assays have been received for the first eight holes, testing approximately 3% of the modelled altered ultramafic target horizon. Importantly, all eight holes for which assays have been received have intersected highly anomalous PGE mineralisation, including:

• MTRC003D: 27.0 metres @ 0.33g/t 3E , 0.12% Ni & 0.05% Cu from 198.0 metres

• MTDD001D: 18.0 metres @ 0.29g/t 3E, 0.11% Ni & 0.05% Cu from 182.0 metres

• MTRC009D: 10.2 metres @ 0.23g/t 3E, 0.09% Ni & 0.01% Cu from 199.0 metres

The depth of mineralisation is consistent with the previously modelled target horizon however the initial geological interpretation of these results indicates that a secondary control(s) on mineralisation are likely influencing the local distribution of grade and continuity. Nonetheless, the confirmed presence of PGE mineralisation within the tenement, over 450 metres from the Callisto discovery suggests that the prospectivity of the area for future PGE discoveries remains.

Importantly, thickening was observed in the sediments to the south in holes MTRC0011AD (38.0 metres) and MTRC005D (49.0 metres). This thickening is interpreted to be a key control on mineralisation, being the source of both sulphur and fluid which may facilitate the local enrichment of PGE mineralisation. Both MTRC0011AD and MTRC005D have been logged, cut, sampled, and submitted to the laboratory, with assays expected in the next 4-6 weeks.

Managing Director and CEO, Chris Hansen, commented :

“The historical focus of Mt Thirsty has primarily focussed on the near surface oxide Resources, with the more recent PGE exploration occurring in largely untested geological horizons. Over the past weeks our geological understanding of the potential controls on mineralisation has evolved rapidly and we continue to dynamically adjust our exploration model to reflect this. We are reassured to have received highly anomalous PGE mineralisation in all holes completed to date, and more importantly the two recent most holes, MTRC0011AD and MTRC005D, have intersected significantly thicker sedimentary packages, which are interpreted to be a key control on mineralisation.

With a further seven holes planned as part of the aggressive Phase I drill campaign, we look forward to testing the majority of the prospective strike horizon at Mt Thirsty over the next four weeks. Following the completion of the PGE drill campaign the multipurpose drill rig will then move to the western margin to test the recently identified lithium potential where eight pegmatite outcrops have been mapped over a 1,000-metre strike horizon. We look forward to keeping shareholders updated on a regular basis as our understanding of the scale and nature of this new geologic system continues to develop.”

Despite the first 12 holes only intercepting thin mineralised horizons, results from these holes have been instrumental in refining the geological model by synthesizing geochemical, geological, and more recent geophysical data, to refine the remaining Phase I drill campaign to areas which exhibit a similar signature to Callisto.

The current geological interpretation indicates that Callisto style mineralisation may be hosted within a north-south trending zone of demagnetisation, resulting in localised alteration and remobilisation of mineralisation. This interpretation is supported by the results which have been received to date from the north-east corner of the target area and geophysical interpretations (Figure 1). Importantly, a continuous demagnetised zone has been interpreted to run the entirety of the MTJV licence (see Figure 1), exhibiting a similar low magnetism geophysical signature similar to the Callisto host lithologies. As ultramafic formations are highly magnetic, this suggests a zone of strong alteration and potential remobilisation of minerals.

With over 90% of the altered ultramafic target horizon remaining untested, and a large demagnetised zone remaining largely untested, the Mt Thirsty complex remains highly prospective for additional PGE discoveries. The remainder of the Phase 1 drill campaign has been reprioritised and is expected to be completed within the next 4 weeks.

LITHIUM PEGMATITE UPDATE

In addition to the untested PGE potential, the MTJV continues to undertake a detailed geological review assessing the western margin of the Mt Thirsty licences for lithium-caesium-tantalum (LCT) potential, with historical drilling and mapping previously documenting pegmatites within the MTJV licence area.

Preliminary geological mapping in the area has identified eight pegmatite outcrops on the western margin of the Mt Thirsty licences over a strike extent of 1,000 metres (Figure 2), with preparations for an initial 11-hole program (1,650 metres) already underway with drill pads having been prepared.

Importantly, 150 metres to the west of licences held by the MTJV is the Mt Thirsty pegmatite where Galileo previously reported a series of steeply dipping, north-south trending pegmatites. Six grab samples of micaceous (lepidolite) pegmatite were sampled by Galileo returning an average assay grade of 2.3% Li2O, 1.87% Rb and 476 ppm Ta205[4] .

THE FOLLOWING TABLES ARE PROVIDED TO ENSURE COMPLIANCE WITH THE JORC CODE (2012 EDITION) FOR THE REPORTING OF EXPLORATION RESULTS.

MT THIRSTY PROJECT

SECTION 1 – SAMPLING TECHNIQUES AND DATA

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

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 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 (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.	• Sampling was conducted using Diamond Core (DD) drilling rig. • For DD drilling, samples were collected as half-core (NQ2) at geological intervals defined and mineralisation boundaries and is considered appropriate for this style of mineralisation. • Diamond drilling was used to obtain half-core samples of various lengths (minimum 0.2m), from which 1-3kg of material is collected for assaying. • QAQC Standards and Blanks were collected/inserted at a rate of approximately 1 in every 20m (maximum) through pre-determined mineralised zones. • Samples were sent to an independent commercial laboratory where samples are oven dried, crushed, pulverised and split to produce a 50g charge for fire assay. • Sampling and QAQC procedures are carried out using Greenstone protocols as per industry best practice.
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). _	• DD drilling was HQ2 to approximately 150m, remained of holes was drilled HQ2. Core was oriented every 3m where possible using an electronic orientation tool.
Drill sample recovery	• Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximise sample recovery and ensure representative nature of the samples. • Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material.	• Core recovery was estimated using the drillers recorded depth marks against the length of the core recovered, this is verified and confirmed by Greenstone staff. • No sample recovery issues have impacted on potential sample bias.
Logging	• Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. • Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. • The total length and percentage of the relevant intersections logged.	• All drillholes are logged in full. • All drilled intervals are logged and recorded. • Data was recorded for regolith, lithology, veining, fabric (structure), grain size, colour, sulphide presence, alteration, oxidation state, fractures, and RQD. • Logging is both qualitative and quantitative in nature depending on the field being logged. • Logging of diamond core was qualitative and diamond core was photographed. • Diamond core is stored at the Company’s core yard on-site. • Greenstone considers the data to be of an appropriate level of detail to support a resource estimation.

Criteria	JORC Code explanation	Commentary
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.	• Diamond core is cut in half along the orientation line. The right side of the core is collected for analysis. • Sample preparation was conducted at ALS Global laboratories using a fully automated sample preparation system. Preparation commences with sorting and drying. Oversized samples are crushed to <3mm and split down to 0.5-3kg using a riffle splitter. Samples are then pulverized and homogenized in LM5 Ring Mills and ground to ensure 85% passes <75µm. • The sample size is considered appropriate for this type and style of mineralisation.
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 (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established.	• Homogenised and pulverised samples are mixed with flux composed of PbO and SiO2 with variable amounts of borax, soda ash and other reagents. The flux and sample are mixed, then heated at high temperature (>1,000°C) to decompose rock lattices and allow precious metals within the sample to be collected into a lead button. The button is placed in a porous cupel and heated again in an oxidising environment to convert lead to lead oxide that is absorbed into the cupel, leaving the precious metals behind as a doré bead or prill. The gold, platinum and palladium content of the prill is then determined through Inductively Coupled Plasma Mass Spectrometry (ICP-MS). The detection level for the Fire Assay/AAS technique is 0.001ppm for Palladium (Pd) and Gold (Au) , 0.0005 for Platinum (Pt). • Rhodium (Rh) analysis is carried out in a similar manner to PGM by lead collection fire assay, with the additional step of gold inquarting during the fusion process and modified cupellation. Analysis is carried out using ICP-MS instrumentation. • A four-acid digestion method which utilises a combination of nitric, perchloric, and hydrofluoric acid with a final dissolution stage using hydrochloric acid with a 48 element suite including Ag, Al, As, Ba, Be, Bi, Ca, Cd, Ce, Co, Cr, Cs, Cu, Fe, Ga, Ge, Hf, In, K, La, Li, Mg, Mn, Mo, Na, Nb, Ni, P, Pb, Rb, Re, S, Sb, Sc, Se, Sn, Sr, Ta, Te, Th, Ti, Tl, U, V, W, Y, Zn, Zr with ICP-MS finish. • Laboratory QA/QC controls during the analysis process include duplicates for reproducibility, blank samples for contamination and standards for bias. • 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. • The use of twinned holes. • Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols.	• All drilling and significant intersections are verified and signed off by the Exploration Manager for Greenstone Resources who is also a Competent Person. • No pre-determined twin holes were drilled during this program. • Geological logging was originally captured on formatted

Sampling, collar, and laboratory assay data is captured electronically and also sent to SampleData. The official database is stored and backed up by SampleData, a copy of which is sent to Greenstone for geologists use. Uploaded data is reviewed and verified by the geologist responsible for the data collection. • No adjustments or calibrations were made to any assay data reported.
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.	• Drill hole collar locations are pegged out by supervising geologists using handheld GPS, accurate to +/-3m. This has been considered as sufficiently accurate for the purposes of drillhole accuracy. • The drilling rig was sighted using a compass. Drill hole angle was set using an inclinometer placed on the drill mast prior to collaring the hole. • Down-hole surveying was completed at nominal intervals using a Single-shot reflex tool, providing sufficiently accurate down hole accuracy

All reported intervals are however reported as downhole intervals only. • No drilling orientation and/or sampling bias have been recognized in the data at this time.
Sample security	• The measures taken to ensure sample security.	• The 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 sample chain of custody has been maintained by ALS Global’s Kalgoorlie Laboratory for transport to analysis laboratoryin Perth
