TEM completed 91 holes for 7,410 metres of drilling. Assays from 6,346 metres of aircore and reverse circulation drilling have returned with the remaining diamond drill program results expected during Q1 2023. The initial review of results shows highly anomalous results for a number of critical metals including Nickel, Tungsten, Cobalt and Rare Earths Elements (REE). Meleya Project Background The Meleya Project is part of Tempest Minerals’ flagship Yalgoo Portfolio that extends over a footprint of more than 1,000km2. The interpreted Yalgoo Greenstone Supracrustal unit encompasses a rough area of 4,000km² indicating that Tempest holds approximately 25% of the active exploration leases regionally. Tempest has for some time considered the target zones at Meleya to represent one of the most exciting greenfields base and precious metal upside exploration opportunities in the industry today. After noting a discordant regional geophysical signature 1 in 2019 , TEM identified 50 km (strike length) of a previously unrecognised and unexplored segment of the Yalgoo Greenstone Belt - the Meleya Project - and has been actively exploring it since, including extensive fieldwork and geochemical sampling. 2 In early 2022 , TEM drilled the first 2 holes into the new province at the Orion Target. This drilling and follow-up work indicated the presence of significant mineralisation and highlighted the increased regional potential. 3 In September 2022 , TEM commenced a second larger drilling campaign aimed at testing two coincident anomalous geochemical and geophysical (magnetic) Tempest Minerals Ltd │ ACN 612 008 358 Phone: +61 8 9200 0435 Address: Level 2, Suite 9, 389 Oxford Street, Mt Hawthorn, WA 6016 Page 1 | 31 ASX : TEM 2023-02-14 | Meleya Update - Critical Metals In Regional Drilling Program targets and additionally a wide-spaced shallow regional percussion drilling program. The completion of this 4 drilling was announced in December 2022 . 2022 Drilling Overview Following on from the mineralisation discovery made at the Orion target in March 2022, TEM commenced a larger scale regional drilling program 5 with the aim to collect geochemical data to augment the existing soil sampling or test areas where surface sampling is more challenging or inappropriate. The regional program also provides the opportunity to correlate geology from surface mapping and deep diamond holes across large distances and provide targets for follow-up drilling. This shallow drilling was conducted on nominal 500m x 500m spacing and the campaign in Q4 2022 with an area of some 4km x 4km of the central Meleya Belt tested. The program - phase 1 of a number of possible campaigns - consisted of 6,346 metres of aircore and reverse circulation drilling, though this represents a small fraction of the total Meleya Project. Figure 02: Meleya Project Project Overview Geology The geology of the Meleya Project was previously interpreted from geophysics and several large-scale 6 mapping and surface geochemistry campaigns . Current drilling has further confirmed previous geological interpretations of the region and provided multiple new insights. E.g. The Clover target RC transect provides 2.5km of lateral lithological definition down to 200m of depth into fresh rock. The primary lithology is mafic and felsic ‘greenstones’ wrapped around a shallow intermediate intrusion known as the Walganna Suite, and is flanked on the eastern side by felsic volcanics interpreted as a continuation of the Big Bell Suite. Structures - both stratiform and crosscutting ‘feeder’ zones - are considered the source of the multiple mineralisation styles (Skarn, Volcanogenic Massive Sulphides (VMS), Intrusion Related Gold (IRG) deposits and Orogenic vein style gold) present in the district. Page 2 | 31 ASX : TEM 2023-02-14 | Meleya Update - Critical Metals In Regional Drilling Program A number of these structures were intersected by the most recent grid drilling and appear to host a number of critical minerals previously not observed at Meleya including Rare Earths, Nickel and Tungsten. Figure 03: Meleya Project Drilling Program Overview Critical Metals Tungsten: Highly anomalous Tungsten is present in numerous holes and appears related to a Skarn type mineralised system. WARDH83 was drilled through regolith to a depth of 40m and intercepted a potentially weathered skarn zone peripheral to an interpreted mafic sill with significant visible extent in aeromagnetic surveys. This zone was likely reactive to fluid migrating from an intruding dolerite sill interacting with the fertile greenstones in this portion of the belt. WARDH83 hosted the best intercept 3m @ 0.54% Tungsten TriOxide (WO3) and 0.07% Cobalt from 21m. This is ~600m downtrend of the skarn alteration in WARDH75 on the Clover drill line. Although assays remain outstanding for the diamond hole in this area, visibly skarn-altered zones in WARDH75 highlight consistent enrichment in tungsten within the horizon. This alteration was traced along the sill contact to hole WARDH139 and spans an approximate contact length of 450m. WARDH139 sampling uncovered Tungsten grades of 0.09% WO3 (710ppm W) from 166m followed by 0.11% WO3 (930ppm W) within a a total intercept of 4m @ 0.05% WO3 (428ppm W from 163m). Another zone due east in hole WARDH135 contained intercepts of 1m @ 0.15% WO3 (1,220ppm W) from 159m. As this hole Page 3 | 31 ASX : TEM 2023-02-14 | Meleya Update - Critical Metals In Regional Drilling Program was abandoned at 167m due to excess downhole water, further drilling may be required to ascertain the full extent of this mineralisation. An additional anomalous tungsten zone was located in WARDH122 with 1m @ 0.26% WO3 (2,050ppm) from 45m. This was hosted at the base of the regolith within the Big Bell granite suite. Mineralogical and hyperspectral work is underway to determine and understand the anomalies and how to best target these horizons. In particular, the extent of the mineralisation which was encountered at the end of hole WARDH139 which ended on 0.11% WO3. Key Intercepts: Zone 1 ● 3m @ 0.54% WO3 (4,270ppm W ) and 0.07% Co (699ppm) from 21m (WARDH83) ● 1m @ 0.26% WO3 (2,050ppm W) from 45m (WARDH122) ● 1m @ 0.15% WO3 (1,220ppm W ) from 159m (WARDH135) ● 4m @ 0.05% WO3 (428ppm W ) from 163m (WARDH139) Including 1m @ 0.11% WO3 (930 ppm W) from 166m (EOH sample) ● ● 1m @ 0.09% WO3 (710ppm W ) from 145m (WARDH139) ● 1m @ 0.06% WO3 (520ppm W ) from 150m (WARDH142) Nickel: The most prominent Nickel enriched zone 5m @ 0.11% Nickel and 0.09% Chromium appears in WARDH156 hosted in an altered mafic to ultramafic volcanic . Hole WARDH156 additionally contains enrichment in Tungsten at 128.5ppm and Lithium at 193ppm. Assays indicate an ultramafic source with MgO (Magnesium Oxide) averaging at 19.8% and FeO (Iron Oxide) averaging at 11.6%. This is an exciting development for the Meleya Project, as Nickel bearing mafic to ultramafic geology has previously not been documented but 7 geology of this type can be the ideal host for significant Nickel deposits . An additional zone with a similar metal content was seen in hole WARDH150 with 9m @ 0.05% Nickel + 0.06% Chromium from 36m. This represents a separate crustal setting just over 3km to the east of DH156 and is hosted within a demagnetised altered intrusive. Modelling is being carried out to better understand the nature of these high priority mineralisations. Key Intercepts: Zone 1 ● 5m @ 0.11% Ni + 0.09% Cr from 101m (WARDH156) And Zone 2 ● 9m @ 0.05% Ni + 0.06% Cr from 36m (WARDH150) Copper-Zinc: The distribution of anomalous Copper-Zinc mineralisation throughout the drill program is primarily concentrated in structures propagating from the Clover line (see figure 3). Some anomalies appear to be stratiform or stratigraphically hosted and elevated values correlate between drill lines along strike of the interpreted boundaries of the main greenstone package first delineated by the initial Orion Diamond Holes WARDH072 8 9 and WARDH73 . Page 4 | 31 ASX : TEM 2023-02-14 | Meleya Update - Critical Metals In Regional Drilling Program Initial work indicates these anomalies have a VMS (volcanogenic massive sulphide) or similar geochemical fingerprint 10 to a mineral assemblage, in particular that of the Gossan Hill Deposit at Golden Grove. This mode of mineralisation is one of the primary exploration targets of this drilling campaign and the anomalous Cu-Zn in this form is particularly strong along the Clover drill line at the convergence of several regional scale fault and shear zones and later stage regional dolerite dykes. Multiple holes located in the ‘Clover Target’ drill section encountered broad zones of highly anomalous base metals on the western and eastern margins including: As seen in figure 4 these grades are significantly elevated - up to 4 times the normal regional geological background values - and combined with the intense alteration suggest a wider mineralising system at play such as VMS or skarn. This is in line with the geological theory underpinning the Meleya Belt and as originally hypothesised during the Orion Diamond program in early 2022 and is encouraging for further exploration. Figure 04: ‘Clover Target’ Drill section with Copper/Zinc enrichment Key Intercepts: ● ● ● ● ● ● 163m @ 149ppm Cu + 101ppm Zn + 126ppm Ni + 309ppm Cr (WARDH79) 71m @ 186ppm Cu, 152ppm Zn, 106ppm Ni and 333ppm Cr (WARDH146) 4m @ 353ppm Cu + 425 ppm Zn + 149ppm Ni (WARDH145) 1m @ 617ppm Cu + 93ppm Zn + 126ppm Ni (WARDH 110) 118m @ 138ppm Cu, 120ppm Zn (WARDH138) ○ Including 1m @ 750ppm Cu + 97ppm Zn + 138ppm Ni (WARDH138) 88m @ 132ppm Cu, 99ppm Zn, 134ppm Ni and 281ppm Cr (WARDH139) Page 5 | 31 ASX : TEM 2023-02-14 | Meleya Update - Critical Metals In Regional Drilling Program Rare Earth Elements and Scandium: Concentrations of rare earth elements in particular Cerium, Lanthanum and Yttrium have been discovered in significant proportion at the base of regolith across several key structural contacts on the north-eastern and south eastern corners of the drill program. Hyperspectral logging is being undertaken to understand the nature of their mineralisation, a strategy will be designed to follow up and determine controls to target. Key Intercepts*: ● 6m @ 0.13% REO (Rare Earth Element Oxide) - 686ppm Ce + 348 La + 86pm Y from 51m ○ Including: 3m @ 0.2% REO - 1085ppm Ce + 348ppm La + 135ppm Y from 48m And ● ● ● ● 4m @ 0.09% REO from 23m in WARDH150m (552ppm Ce + 238ppm La + 50ppm Y) 4m @ 0.05% REO from 32m in WARDH79 (244ppm Ce + 144ppm La + 194ppm Y) 6m @ 0.03% REO from 9m in WARDH121 (237ppm Ce + 69ppm La + 4ppm Y) 1m @ 0.05% REO from 22m in WARDH138 (18ppm Ce + 375ppm La + 331ppm Y) (WARDH145) ● 7m @ 0.011% Sc2O3 (91ppm Sc) from 51m ○ Including 3m @ 0.013% Sc2O3 (104ppm Sc) from 52m ● 4m @ 111ppm Sc2O3 from 44m (WARDH146) * Note the method for assay 4 acid digest is not the preferred method for dissolving and assaying rare earth element mineralogy and is just an estimate showing only 4 of total 15 rare earth elements. Conclusions Visibly altered domains correlate well with anomalous metal endowment. Unexpected high levels of nickel, tungsten and rare earth elements in particular may relate to zones of potential VMS style mineralisation hosted within the interpreted greenstone belt or potential Skarn style mineralisation. The drill program has highlighted critical mineral mineralisation is concentrated along many major lithological and structural contacts. In particular some of the highest grades of Copper, Zinc, Tungsten, Cobalt and REE are positioned around the Clover target in the southern portion of the drill program. Furthermore, the northern lines also showed notable grades of Nickel and REO (Rare Earth Element Oxide). This program has vectored in on the prospectivity of the “Anaesthesia” target (Figure 3), coincidently this target falls on a large bullseye aeromagnetic target. Initial data indicates that there is a relationship between anomalous geochemical anomalies present around the Clover target increase proportionally to the density of structures. The Anaesthesia target is a point within the interpreted greenstone belt that has bifurcated, likely from intense faulting and may provide an ideal host environment for major deposits. This same fault is aligned with some of the broadest zones of copper and zinc on the eastern end of the Clover line while also appearing along strike of the same interpreted stratigraphic horizon as the Orion and Clover Cu-Zn enhanced greenstones. The zone also has been interjected by two east-west striking dykes and the large belt concordant mafic intrusion interpreted to have influenced the intense alteration responsible for the highest tungsten grades. This program has tested laterally and to base of regolith along high priority surface features (including Orion and Clover). Results have indicated that the subsurface is similarly elevated and that further science and technology is required to narrow down and further enhance prospective targets. To date all Meleya diamond holes have been scanned using a Geotek Boxscan which “delivers consistent, non-subjective, automated depth registered imagery, geochemistry, mineralogy, and structural parameters from one mobile core scanning system” 12 . Moreover, priority reverse circulation and aircore hole box scanning will be fast tracked to better understand the complex mineralised alteration encountered across the recent program, applying this data to the wider area will ensure targets are ranked to their utmost potential.

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. ● ● ● ● Reverse circulation and Aircore drilling was used to obtain samples for geological logging and assaying. The Drillhole was undertaken to test geochemical and geophysical anomalies as well as understanding the stratigraphy to enable further target testing. Sample was collected via the cyclone splitter, across the regolith 3 metre composites were taken from the UV bag and in fresh rock 1 metre samples were collected from the split.. All samples were submitted to ALS Laboratories in Perth and were multielement (48 elements) tested via 4 acid digestion (ME-MS61) and a 30g fire assay (AU-ICP21). 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). ● A T450 dual purpose truck mounted drill rig was used to drill reverse circulation and aircore holes. 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. ● Drilling was undertaken using a ‘best practice’ approach to achieve maximum sample recovery and quality through the mineralised zones. Best practice sampling procedure included: ○ Dust suppression, ○ levelled cyclone ○ cleaning of sampling equipment ○ ensuring a dry sample ○ supervision by competent field staff (Geologist and field technician). No relationship between sample recovery and grade is known at this stage: more drilling is required to establish if there is any sample bias. Samples were dry and recoveries were excellent and usually >95%. Rare sample loss occurred around geological structure. ● ● ● ● ● Page 10 | 31 ASX : TEM 2023-02-14 | Meleya Update - Critical Metals In Regional Drilling Program | JORC TABLE 1 Logging ● ● ● Sub-sampling techniques and sample preparation ● ● ● ● ● ● Quality of assay data and laboratory tests ● ● ● Verification of sampling and assaying ● ● ● ● Location of data points ● ● ● 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 logging is both qualitative and quantitative. The total length was verified between the sample bags and the drill rods down hole. Significant changes in sample bag volumes were noted down. A 2-3kg sample (split) was split via the cyclone. QAQC entailed a revolving Blank/Standard/Duplicate at every 20th sample downhole. The duplicate was split by the driller using the cyclone. The cyclone was cleaned between each run to ensure sample quality. Field and laboratory duplicates, certified reference sampling and blank standards will be used regularly throughout the sampling process to ensure quality and appropriateness of the assay technique(s). Tempests database is hosted in a cloud database system All QAQC data was reviewed in Shewhart plots with all at acceptable ranges As the assays are from an initial drilling campaign, independent referee laboratory analyses or twinned holes are not yet applicable. Geological logging was completed using in-house logging data systems. All data entry is carried out by qualified personnel. Standard data entry is used on site, and is backed up directly to a cloud-based database. Drill hole locations collected by handheld GPS (±3m horizontal, up to 12m vertical error - however error was consistently below 4m.
