ASX ANNOUNCEMENT
29[th] September 2023
High-Grade Sampling Results from the la Cienaga Copper-Gold Project
Highlights:
-
EVR completed a systematic sampling program at the la Cienaga CopperGold Project.
-
Average values from a total of 119 samples assayed at 0.88% Cu, 2.51g/t Au, 5.61g/t Ag.
-
In the Eagle Zone, sample #1844128 returned the highest-grade gold assay
o 83.87g/t Au, 2.9% Cu, 7.7g/t Ag
-
Further detailed mapping and sampling including trenching will be completed and results will be used for drill target evaluation.
-
The New Standard claims pegged in 2021, have been rationalised to focus attention on a strong structural anomaly.
EV Resources Limited (ASX: EVR) (“ EVR ”, or “ the Company ”) is pleased to announce that it has completed an initial geological review of the la Cienaga copper-gold project within la Paz County, Arizona, USA.
The Project is located in the Buckskin Mountains of West-Central Arizona, and covers ground in the Cienaga sub-district which accounts for 85% of all the gold produced from the Buckskin District, although no mining has occurred since the 1920s. This follows the consolidation of the ground position at the New Standard project (See ASX announcement of 10[th] May 2023 “New Standard Project Land Position Consolidated”).
The dominant mineralisation of the Buckskin District is related to a regional burial event caused by tectonic over-plating. The Buckskins experienced a regional MVT-style mineralisation event in which Iron-Oxide/Copper mineralisation has emplaced along stratigraphic controls within the Paleozoic Sedimentary Rocks. Subsequent extension and rifting have affected the area. A distinctive feature of the Eagle Zone is vertical sedimentary formations which host mineralisation

Eagle Zone – Maiden Exploration Programme
The recently pegged Eagle Zone (See Map 1, above and for more detail Map 2, below) has returned excellent sampling results. For a full list of Sample Results see Table 1, below.
The Eagle Zone contains numerous old mine workings and more than 4,000m of underground workings are noted in State and County records. Many of the underground developments were completed prior to 1910 and minimal reporting exists. The historic mining in the Eagle Zone is concentrated within the craggy peaks and outcrops of the Double Eagle Shaft and Gray Eagle Shaft. Historic records, maps, and sections are being integrated into a working 3D model. There are numerous existing access roads and only minor rehabilitation will be required to mobilize drilling operations.
In the Eagle Zone, copper-oxide mineralisation occurs in conjunction with massive hematite, hematite-breccia, and local mushketovite (hydrothermal magnetite). Copper-Oxide species are more advanced and include malachite, chrysocolla, azurite, brochanthite and others. Later emplacement of sub-vertical volcanics is along trend with the vertical sedimentary rocks and west of a 100m-thick Tertiary basalt flow. The historic mining area is focused on mineralised contacts of the sedimentary sequence. Numerous vein trends extend to the southwest, a basement detachment fault has also been observed nearby.

The exposed portion of this zone presents as a block of highly mineralised (iron-oxide/copperoxide) paleozoic carbonates and siliciclastic sediments that have been rotated to a sub-vertical orientation. More than 5km of structurally controlled quartz vein mineralisation has been identified along this trend.

New Standard Zone – Revisited and Refocused
The New Standard Project Area was visited during the summer field season. Access from Parker, AZ is 15 miles by paved and dirt road. Previous sampling of the project in 2022 was made available to Mineoro by EV Resources, this information was used to supplement a complete geologic reconnaissance.
The New Standard Project can be broken into the East and West, divided by the Central Arizona Project Water Canal. The East half was visited briefly and had been previously mapped and sampled in 2022. Mineralisation observed in the East Half is hosted in carbonates, Iron-Oxides and Copper-Oxides is patchy and discontinuous, although concentrated along stratigraphic controls. This land position has been dropped, to focus exploration on the West Half - auriferous mineralisation here is related to both low-angle structural zones and sub-vertical structures which host volcanic-related mineralisation.

JORC CODE, 2012 EDITION – TABLE 1 REPORT TEMPLATE
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 (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. |
•A total of 119 rock chip, channel samples, and ore characterisation samples were collected from outcrops and accessible mine development. This is in addition to 190 surface geochem samples from previous efforts (refer announcements dated 15thMarch 2022 and 15thSeptember 2022). •All, of the 119 samples taken from this project are rock chip derived either directly from exposures or from extant dumps (or composites of the two). •Samples were collected to be representative of the outcrop; typical sample mass was 1-3 kilograms; the mass of samples collected ranged from a low of 0.16 kg to a maximum of 4.6 kg with an average mass was 1.6 kg. The samples were collected for laboratory analysis and no analytical instruments were used in the field. •Sample locations targeted visible mineralisation, alteration, and structural features of interest. |
| 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). |
•Some drilling was noted on the property but no information is available from this work. |
| 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 data is available for the property. |

| 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 surface samples have complete geologic logs. No drilling has been completed. •Geological logging of the surface samples was qualitative and included lithology, alteration, and mineralogy. •All sample materials and locations were photographed. •Rock chip sample descriptions include lithology, structural features, orientation of structure, and mineralogy. •Surface samples are not conventionally used for Mineral Resource estimation; results from the 2022-2023 field investigations will not be applied to Mineral Resource estimation. |
|
| 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. |
•Surficial samples were taken from dry outcrops and not split in the field. •Samples were shipped via Fedex to American Assay Laboratories (AAL) in Sparks, Nevada, USA for sample preparation. •Sample preparation techniques in pv-1 procedure, which includes: oCrush to 70% passing 2 millimeters oRiffle split a 250 gram subsample oPulverize 250 g to at least 85% passing 75 microns •The sample preparation technique is designed to homogenize the material for subsampling representative splits for gold fire assay and whole-rock ICP analysis. •Quality Assurance/ Quality Control procedures for assay data include insertion of certified gold and or copper standards, duplicates and blank samples of crushed marble. •Certified standards were inserted into the sample stream as one certified standard (pulp) and one blank (either certified pulp or uncertified coarse material) approximately every twenty samples. •Certified standards and blanks originate from Ore Research and Exploration, Bayswater North, Victoria, Australia or KLEN International Pty Ltd. located in Neerabup, Western Australia. •The coarse blank samples are landscape marble chips acquired from a home improvement store. This material does not have certified values for the elements of interest, but it is expected to have low abundance of gold, silver, and copper compared to the surface samples that target mineralisation. The coarse blank samples will go |

| Criteria | JORC Code explanation | Commentary | |
| through the same sample preparation process as the surface samples. Any cross contamination from sample preparation equipment will be evident in the results of the blank samples. •In addition to standards and blanks included within the submitted samples, AAL inserted internal blanks and standards during the execution of the assaying program. •In the field, discrete features with consistent mineralogy were targeted to collect representative samples. •Silicification, structural controls, and altered volcanic rocks were sampled in addition to the Iron-Oxide/Copper-Oxide mineralisation of historic mining activities. Neither gold, nor silver were visible in hand sample. Sample sizes are considered appropriate for the 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 (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established. |
•Analytical methods selected are gold fire assay and Inductively Coupled Plasma (ICP) with fiver-acid digestion ((hydrochloric, hydrofluoric, perchloric, nitric and sulphuric) followed by an by ICP- OES. AAL method code FA-ICP to determine gold via fire assay and ICP- Atomic Emissions Spectrometry (ICP-AES) on a 30-gram charge. Gold results from this technique are considered total. •AAL method code IO-4AB51 to determine whole-rock composition via ICP-Mass Spectrometry (ICP-MS) on a 0.25-gram charge after digestion with nitric, sulphuric, perchloric, hydrofluoric, and hydrochloric acids. Silver, copper, and iron results from ICP-OES are considered total. Refractory minerals, like barite and rutile, may not be fully digested, and therefore, barium and titanium results may be partial. Tin and tungsten minerals and rare earth oxides may not be fully digested. •No analytical tools, like handheld XRF instruments or portable spectrometers, were used in the field. •Quality Assurance/ Quality Control procedures for assay data include reference samples of known composition. •The Certified Reference Material (CRM) samples are prepared pulp samples of OREAS and KLEN laboratory standards. Results from these samples will be compared to the certified values to determine if an analytical bias exists. |

| • | |||
| 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. |
•Most mineralised outcrops were previously mined or developed for exploration. These locations were confirmed during the initial site visit and targeted for sampling. •No drilling samples were available for verification. |
|
| 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. |
•Surface sample locations were determined in either Universal Transverse Mercator (UTM) coordinates using North American Datum 1983 (NAD 83) or World Geodetic System (WGS84). •Sample locations were measured with a Garmin GPSMAP 64sx handheld GPS unit with 3-meter horizontal accuracy. These data were later refined using Google Earth to identify exact locations from aerial images available on that site; 3D coordinates (WGS84 Latitude and Longitude decimal degrees) were then determined for each site and recorded in the project database. •Sample locations were registered to the topographic surface generated from 10-meter elevation contours from the United States Geological Survey (USGS) Digital Elevation Models (DEM) to obtain elevations. •The resolution of the DEM is limited but is adequate for this early- stage exploration study. •Mine workings and mineralised outcrops were sampled if accessible. Surface sample locations were determined by distribution of mineralisation, as well as historic prospects and mines. Coordinates of drill collars, that had not been reclaimed, were located via handheld GPS, decline and azimuth (True North) determined via magnetic Brunton pocket compass (± 0.5o accuracy). |
|
| 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. |
•Mineralised exposures were sampled, where accessible and not based on any spacing protocols. The distribution of historic prospects, mines and surface mineralisation within the Project area is randomly spaced. •Workings are spaced at random intervals. •The sampling discussed here is reconnaissance in nature only. No definition of“ore”or resources can be inferred. |
3
| Criteria | JORC Code explanation | Commentary | |
| •Compositing has not been applied to surface samples. | |||
| 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. |
•Samples were predominantly taken on mineralised structures; perpendicular where thickness warranted, otherwise laterally along strike or as random sampling of material on the dumps. •The surficial samples do not have an orientation relative to mineralised structures, as drillhole samples would. •Because sample locations were selected to characterize mineralised material, there is an inherent sampling bias introduced from the sampling technique. |
|
| Sample security |
• The measures taken to ensure sample security. | •Samples collected on site remained in the custody of EV Resources contract geologist until they were delivered to the laboratory for preparation and analysis. |
|
| Audits or reviews |
• The results of any audits or reviews of sampling techniques and data. |
•No audits have been completed for the 2022-2023 surface sampling program. •Results from the 2022-2023 sampling program will be compared to results previously reported for the property. |
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 total area currently under claim by EV Resources in this project area is approximately 1,142 Ha (2,820 acres). •EV Resources recently completed staking of 18 claims on the GE Target located within the Cienega Project area. The total area of the GE Target currently under claim by EV Resources is approximately 370 acres (~150 Ha). •Land adjacent to the current claims is open, and additional mining claims could be staked in other prospective areas. •There are no known impediments to obtaining the permits required for exploration drilling in this area. •Tribal lands, the Central Arizona Project aqueduct, and nearby Wilderness Study Areas may restrict access or eventual development of the Project. |
4
| Criteria | JORC Code explanation | Commentary | |
| Exploration done by other parties |
• Acknowledgment and appraisal of exploration by other parties. |
•The current owner of the Project completed a field survey and confidential report in early 2021. Gold, silver, and copper values reported for surface samples will be compared to the analytical results from the field investigation completed by EV Resources in a qualitative manner. •Documentation of exploration work completed on nearby claims, which are no longer active, states that a magnetometer survey was completed. The results of the survey and the area of interest are not known but could potentially be acquired. •Drill sites have been located in various areas of the project; but it is unknown as to when or who was responsible for this work. •Historic documentation indicates mining and other activities took place in this area in the early part of the 20th century (World War I era). Much of the prospecting looks to have been completed at this time as well. •Mining, milling and cat work was completed in the vicinity of the Pride mine through the 1960’s. No documentation of this work has yet been located. |
|
| Geology | • Deposit type, geological setting and style of mineralisation. | •Iron oxide-copper-gold (IOCG) mineralization is developed along low- angle detachment and mid to high angle structures associated with basin and range extension. |
|
| 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 sealevel in metres) of the 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. |
•Although old drilling has been identified in the form of open holes and cuttings, there is no drilling documentation available for the Project. |
|
| 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. |
•All geochemical results are based on biased surface sampling. •Grade determinations are the results of this sampling and, at this point in the program, will serve as little more than a guide to focusing additional exploration efforts moving forward. |
5
| Criteria | JORC Code explanation | Commentary | |
| • 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. |
|||
| 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’). |
•No drilling samples are available for the Project. •The surficial samples collected do not have a length attributed to them. They represent the feature of interest; the width of each feature is included in the sample description. •Structural orientation data were collected at most surficial sample locations. |
|
| 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. |
•N.A. | |
| 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. |
•Analytical results for surficial samples were not available at the time this report was finalized. The range of grades was unknown. •Mineralized features are structurally controlled and range in width from 0.1 to 15 meters. |
|
| 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 available and reliable exploration data have been presented above. Results from previous investigations have not been presented, due to incomplete information and uncertainty in the data collection process, including sample location, sampling technique, and analytical practices. |
|
| 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. |
•Future exploration work should include geophysical survey methods, namely magnetics; induced polarization and resistivity surveys may also prove beneficial. •Targets for exploration drilling may be developed with surficial geology data and results of geophysical surveys, if available. •Geophysical surveys can provide data to reduce the risk and maximize the value of exploration drilling. |
6
| Criteria | JORC Code explanation | Commentary | |
| •Acquisition of detailed topographic data is recommended for exploration drilling, to establish precise drillhole locations in 3-D space. •Additional surface sampling and mapping to fill in and expand areas already examined. |
