ASX RELEASE
Infill drilling program intersects additional tin mineralisation at Oropesa Tin Project
Elementos Limited (ASX: ELT) has confirmed intersections of near-surface tin mineralisation at its Oropesa Tin Project, Spain, which are significantly broader than previously modelled by its 2021 Mineral Resource Estimate[1] .
The first hole to be completed in Elementos’ nine-hole infill drill program[3] , drill hole ADD_24, returned broad intersections at the margins of the current geological resource, highlighted by the results below:
ADD_24:- 37.9m @ 0.34% Sn from 59.3m

Managing Director Joe David commented, “This is an encouraging result to kick-off our 2022 infill drilling program at Oropesa. The main aim of this program is to upgrade the Inferred Mineral Resources, that reside within the US$30,000/t pit shell[4] , to a higher confidence Resource category. Drill hole ADD_24 targeted the intersection of two significant previously interpreted controlling structures and confirms the continuity of the tin mineralisation at this location, but notably has intersected a much broader zone of mineralisation than currently modelled.

ABOUT ELEMENTOS
Elementos is committed to the safe and environmentally conscious exploration, development, and production of its global tin projects. The company owns two world class tin projects with large resource bases and significant exploration potential in mining-friendly jurisdictions. Led by an experienced-heavy management team and Board, Elementos is positioned as a pure tin platform, with an ability to develop projects in multiple countries. The company is well-positioned to help bridge the forecast significant tin supply shortfall in coming years. This shortfall is being partly driven by reduced productivity of major tin miners in addition to increasing global demand due to electrification, green energy, automation, electric vehicles and the conversion to lead-free solders as electrical contacts.

Section 1 Sampling Techniques and Data
Diamond Drilling Exploration Program, Oropesa Tin Project, Spain – August 2022
| 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. |
• ADD_24 was completed by PQ diameter pre-collar diamond drill core to 29.8m. The remainder of the drill hole was completed recovering HQ diameter drill core. • Only HQ drill core was sampled based on intervals determined by the project geologist and cut using a diamond saw to split the core in half. • Cassiterite mineralisation at Oropesa is rarely visible to the naked eye. Historical exploration mineralogical reports (¹) have reported a strong relationship between tin mineralisation (cassiterite) and sulphide mineralisation. High levels of oxidation of the sulphide mineralisation to iron oxides has been observed and recorded in drill logs from previous drilling campaigns at Oropesa. These oxidised zones occur near the surface (gossans) and within sub-vertical fault zones. Historical drilling data indicates that these highly oxidised zones can contain significant quantities of tin mineralisation (cassiterite). • Observations made from transitional and fresh drill core from the current drilling program are in keeping with historical observations as indicators of potential cassiterite mineralisation zones (± sulphides) at Oropesa. These include silicification of the host sandstones with finely disseminated to semi- massive sulphides (pyrite ± arsenopyrite) with late-stage infill colloform and/or vuggy quartz(¹). Cassiterite mineralisation at Oropesa has also been observed to be associated with intense silicification, leaching and chlorite alteration of the host rocks. Physical or chemical weathering of the fine- grained sulphides has been observed as small voids (pitting) in the host rocks. • Samples have been selected for analysis based on portable NITON XRF analysis taken at 10cm intervals and from visual identification of zones of potential tin mineralisation. The NITON portable XRF data has been used solelyas aguide to sample boundaries for analysis at a commercial |

• A Drillcon Christensen CS 140 self-propelled track mounted drilling rig was used, drilling PQ and HQ standard diamond core. Coring was from surface. • Drill core was collected using a standard triple tube system. • Drill core is not oriented |
| 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. |
• Diamond drill hole core recoveries and RQD are logged. Measurements are taken systematically downhole between core blocks. The maximum increment being 3.1m. • Overall drill core recovery for the mineralised intervals being reported is 89.7% • The mineralisation occurs predominantly in softer sandstone units. A mineralisation depth prediction table is used to assist the drillers in preparing to drill the mineralised zones and maximise recoveries. • Visual assessment of the drill core shows that core recovery is variable with zones of lower recoveries often noted in zones of significant oxidation, mineralisation or structure. No clear relationship exists between tin grade and recovery. |
| 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 andpercentage of the relevant intersections logged. |
• All drill core has been photographed dry and wet. The core is photographed within core boxes, which are identified by drill hole number and start and finish depths. Drill run depths are marked on core blocks. All drill core has been geologically and geotechnically logged prior to being sampled. |

| Geology | • Deposit type, geological setting and style of mineralisation. | • The Oropesa deposit is characterised by replacement-style tin mineralisation (cassiterite and minor stannite) occurring mainly at sandstone-conglomerate contacts in the Peñarroya Basin, a Carboniferous basin formed during the Hercynian/Variscan Orogeny. Reactivation of syn-sedimentary and basin- controlling faults has resulted in complex, folded geometries. Subordinate fault-hosted mineralisation is also present. |
| 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: o easting and northing of the drill hole collaro elevation or RL (Reduced Level – elevation above sea level in metres) ofthe drill hole collar o dip and azimuth of the holeo down hole length and interception deptho 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. |
• All material data for the drill hole information related to this report is located in Table 1 in the body of this announcement. • An estimated Mineral Resource for Oropesa was released to the ASX on 8th November 2021 - “Oropesa Tin Project Mineral Resource Estimate”. Please refer to this announcement for information related to the geological resource. *1 |
| 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. |
• Weighted averaging based on core length and tin grade has been applied to the reporting of mineralized intervals in the body of this report. • The variation in tin grade is not considered significant enough to be material in the compilation of the reported mineralisation intervals. See Table 2 in the body of this report. • No assay results were considered necessary to be truncated for the weighted averaging techniques employed in this report. • No metal equivalent values 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 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’). |
• This report is based on analytical data from ALS, Seville on drill core analyses only. • The drill holes have been targeted to intersect the mineralisation perpendicular to the known mineralisation boundaries. • All drill hole lengths reported in the release are “down hole lengths”. True widths are not known. |
| Diagrams | • Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
• See main 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. |
• The reporting is considered to be balanced. |
| 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. |
• Elementos is reporting results for drill holes that have the following principal objectives; • To convert existing Inferred Resources into Indicated Resources to improve the overall waste-to-ore stripping ratio |
| Further work | • The nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. |
• Complete the proposed diamond drilling program. Current plan is for a total of 9 drill holes for approximately 1,590m. • Completion of a new geological resource model • Converting resources from Inferred to Indicated • Follow-up exploration drill testing on significant open-ended mineralisation trends that were identified during the 2021 exploration drilling program |
