ASX ANNOUNCEMENT
21 November 2022
Confirmed Copper-Silver Zones at Don Enrique Paves Way for Drilling Program
Highlights:
-
Channel sample results have been received from initial sampling in and around a historic exploration drive and crosscut at the Don Enrique Copper Project, located in Jauja Province, Peru.
-
Results indicate continuity of copper-silver-zinc (Cu-Ag-Zn) mineralisation.
-
28 of the 108 samples demonstrate copper values greater than 0.30% and up to 3.22% Cu.
-
17 of the samples recorded silver values greater than 30ppm and up to 585ppm Ag.
-
The exploration drive appears to have been driven into a mineralised halo around the primary breccia structures that outcrop at surface.
-
A geophysics programme consisting of 28.8 line km of IP, and 46.8 line km of magnetics, will commence by the end of November 2022.
-
A drilling permit application, which requires community approval under Peruvian regulations, is being finalised for submission.
EV Resources Limited (ASX:EVR) (“ EVR ” or the “Company” ) is pleased to announce that a programme of channel sampling taken from within, and around an old underground exploration drive and crosscut at the Don Enrique copper project in Jauja Province, Peru, has been completed and results received. EVR announced the commencement of exploration work at Don Enrique in an ASX release dated 30[th] August 2022[1] .
The exploration drive and crosscut were developed in the 1960’s by Peruvian company Cerro de Pasco. EVR’s results demonstrate continuity of copper-silver-zinc mineralisation where underground development permitted sampling. It appears that the underground development was driven into the halo of mineralisation alongside one of two primary parallel polymetallic breccia structures.
All underground sample results have been received, while results for surface sampling directly along the strike of the breccia orebody are awaited (Figures 1 and 2). See Table 1 for a full account of the underground sample results.

A geophysics programme is due to commence on 21 November 2022. In total, 28.8 line km of Induced Polarisation (IP) testwork and a further 46.8 line km of ground magnetics will be conducted along the breccia structures to test what is interpreted, after mapping and geochemical sampling, to be a potential porphyry structure.
A drilling permit application, which requires community approval under Peruvian regulations, is being finalised for submission.
The fieldwork is supported by the local communities, with whom a constructive relationship has been established. Fertiliser, medical equipment and building materials have been supplied to the community as part of an outreach programme following the agreement reached in September 2022.
The community is supplying casual labour to the exploration campaign. EVR has placed community relations at the centre of its site activities and will continue to build this important relationship.

Underground Sampling Programme
Sampling of underground workings was carried out in the historic adits that were developed for exploratory purposes in the 1960’s. A large number of samples have been collected along the west margin of a quartz breccia vein structure, following the strike (footwall).
This structure exhibits a variety of quartz textures including milky white quartz, sinuous quartz saccharoid veinlets, hyaline quartz, and textures such as dog-tooth, buck, and ribbon quartz. This suggests that several generations of silica deposition occurred. In addition, there are sporadic occurrences of carbonate veins including ankerite and calcite.
Copper mineralisation occurs as a dissemination in hydrothermal breccias, narrower quartz veins, and in a strongly silicified dacitic body (see Figure 4).
The identified minerals are predominantly chalcopyrite, traces of bornite, secondary copper such as malachite and azurite, and the local presence of covellite. Silver (Ag), molybdenum (Mo), zinc (Zn), and lead (Pb) mineralisation occur accompanying the Cu mineralisation, in lower concentrations, in the crosscuts perpendicular to the main structure, and towards a short, poorly developed secondary underground working.
Strong Ag and Zn anomalies are reported in the crosscut sampling (see Figures 5 and 6) where silver sulfosalts, sphalerite, and traces of galena have been identified.
The primary quartz breccia vein structure has a variable width of up to 20 metres. A second subparallel structure with a smaller width is located to the east of the main structure. Both structures present a general strike of NNW-SSE and continue for almost 1 km in length.
Figures 7A and 7B demonstrate an idealised cross section of the mineralised structures and their possible behaviour at depth, including underground exploration work, with Cu anomalies in sampling carried out by EV Resources.
The mineralised structures are located in strongly fractured and deformed volcanic units, predominantly pyroclastic rocks that alternate with lava flows, both of dacitic composition. In the vicinity of the mineralised structures, the volcanic units are affected by strong silicification and quartz-sericite alteration.
Some underground crosscuts were also developed, but based on EVR mapping and sampling, they do not completely cut the breccia vein structure. Figure 4 shows a schematic of the layout of the main structure. Samples with anomalous Cu values occur in the crosscuts but not in the margin or the west wall of the structure, which represents a halo of the main structure.

The conceptual model suggests the possibility that the structure is linked to a porphyry-type system at depth. Strongly anomalous values in Mo (Figure 8) are reported at the entrance of the main adit, the northern extension of the vein breccia structure.
The Mo values decrease towards the south in the crosscuts that are towards that orientation. The strong presence of Mo indicates a vector that suggests a possible link to a porphyry-type system at depth, to the north of the structure. This will be tested in the geophysics programme commencing in the week of 21 November 2022.

Underground Channel Sampling Methodology
Geochemical sampling was conducted by collecting samples from continuous channels in underground workings and surface outcrops. Channels were cut with a manual diamond disc saw and sampled after cleaning the walls. Sample intervals 2 metres long, 5 centimetres wide, and 4 centimetres deep were cut, then retrieved using a chisel, and placed in plastic sample bags with a card bearing a unique sample number, and then secured with a plastic clamp.
Once the sampling process was completed, the sample was marked in the field with phosphorescent spray paint. The samples were transported in company trucks to EVR’s Don Enrique camp and kept protected in a warehouse until they were transported to the laboratory in the city of Lima, maintaining the chain of custody.
A total of 257 samples have been collected to date in two sampling campaigns and submitted for analysis, of which one out of every ten are control samples consisting of both blank and duplicate samples. 108 samples have been analysed with results detailed in Table 1.
Samples were analysed at Certimin Peru, an accredited and internationally certified laboratory. Samples of up to 5kg in weight were prepared under the protocol code GO634, dried at 100ºC, ground to 90% passing through #10ASTM mesh (2mm), quartered and pulverized (250g) to 85% passing through #200 ASTM mesh (75um).
The analysis for gold was performed on aliquots of 30g using the atomic absorption (AA) fire assay method and multi-element analysis code G0153, multi-acid digestion, 35 elements, ICPOES. When detection limits are exceeded, additional analysis is applied. Gold was also tested using Code GOO14 fire test-gravimetry. For copper, analysis code GOO39 and for Ag limits, GOOO2 AAS multi-acid code is applied.
Next Steps
A team of Peruvian based geophysical experts have mobilised to site to commence the programme of 28.8 line km of Induced Polarisation Surveys, and 48.8 line km of Ground Magnetometry on Monday 21 November 2022.
The results of surface sampling along the quartz breccia structures are expected in December 2022, and will be used, along with the underground sample results and the geophysics program, to design the drilling program. The drill permitting application is being finalised for submission during this quarter as necessary requirements have now been met.

JORC Code, 2012 Edition – Table 1 report
Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
| Criteria | 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. |
Continuous channels in underground workings and surface outcrops were cut with a manual diamond disc cutter. Samples were 2 meters long, 5 centimetres wide, and 4 centimetres deep. No instruments were used to determine mineralisation. |
| 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). _ |
No drilling reported. |

| Criteria | Explanation | Commentary | |
| 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 topreferential loss/gain of fine/coarse material. |
No drilling reported. | |
| 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. |
No drilling reported. Geology of rock chip channel samples was recorded. Geological records have primarily been quantitative. |
|
| 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. |
At the laboratory, samples were dried crushed and pulverised to 90% passing through #10ASTM mesh (2mm). The sample was then quartered and pulverized (250g) to 85% passing through #200 ASTM mesh (75um). This is considered to appropriately homogenise the sample to allow subsampling for the various assay techniques. One out of every ten samples are control samples consisting of both blank and duplicate samples. Sample sizes are industry standard and considered appropriate. |
|
| Quality of assay data and laboratory tests |
• The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is consideredpartial or total. |
Analysis for gold was performed on aliquots of 30 g using the atomic absorption (AA) fire assaymethod and Multi element analysis code G0153, multi-acid digestion, 35 |

| • 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. |
elements, ICP-OES. When detection limits are exceeded, additional analysis is applied. Gold was also tested using Code GOO14 fire test-gravimetry. For Copper, analysis code GOO39 and for Ag limits, GOOO2 AAS multi-acid code is applied. Analyses are considered partial. One out of every ten samples are control samples consisting of both blank and duplicate samples. Sample sizes are industry standard and considered appropriate. LaboratoryQAQC was undertaken. |
||
| 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. |
No drilling 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. |
Rock Chip channel location were surveyed using handheld GPS. Garmin GPSMAP 64s The grid used was UTM Zone 18, datum WGS84 |
|
| 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. |
Not Applicable as no JORC-2014 resource estimate has been completed. Sampling was of a reconnaissance nature. No compositing of samples or results was applied. |
|
| 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. |
No drilling reported. |

| Criteria | Explanation | Commentary | |
| • 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. |
|||
| Sample security | • The measures taken to ensure sample security. |
Sample chain of custody was managed by the employees of EV resources. All samples were bagged and tied in numbered plastic bags, grouped into larger tied polyweave bags in the field. Samples collected in the field were transported by geological staff to the Don Enrique site base, then directlyto the lab. |
|
| Audits or reviews | • The results of any audits or reviews of sampling techniques and data. |
No audits or reviews were deemed necessary as this work is purely qualitative assaying for first-pass explorationpurposes. |
Section 2 Reporting of Exploration Results
(Criteria listed in the preceding section also apply to this section.)
| Criteria | 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. |
Don Enrique Project is made up of 4 mining rights: Cocoa Beach, Don Enrique 85, Chaupiloma 2008, and Chaupiloma 2007. It is under a purchase option agreement with a local company that is the holder of the 4 mining concessions that cover a total of 1802 hectares. There are no archaeological remains and it is not included in any national park which prevents its normal development of mining exploration. It is located within two communities, Quero and Yauli. |
| Exploration done by otherparties |
• Acknowledgment and appraisal of exploration by other parties. |
|
| Geology | • Deposit type, geological setting and style of mineralisation. |
Don Enrique corresponds to a Cu-Ag-Pb-Zn intermediate sulfidation polymetallic epithermal deposit with some Au credits. It is a breccia vein structure ranging from 5 to 20 meters wide and 1200 meters long, occurring irregularly on strike. It is housed in volcanic rocks, pyroclastic units that alternate with lava flows of dacitic composition. Development of hydrothermal breccias cuttingthrough the breccia vein structure.

|||
| 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: • easting and northing of the drill hole collar • elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar • dip and azimuth of the hole • down hole length and interception depth • 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. |
No drilling was undertaken. | |
| 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. • 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. |
No drilling was undertaken. No averaging or aggregating of rock chip results was undertaken. Individual results have been 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. |
No drilling was undertaken. No geometry or width is reported with rock samples. |
evresources.com.au
311-313 Hay St Subiaco, Western Australia 6008 +61 (0) 8 6489 0600 [email protected]
| Criteria | Explanation | Commentary | |
| • If it is not known and only the down hole lengths are reported, there should be a clear statement to this _effect(e.g. ‘down hole length, true width 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. |
No drilling was undertaken. A sample location plan is included as Figures 1 to 3 and Figure 5. |
|
| 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. |
All results have been reported. | |
| 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 meaningful & material exploration data has been reported. | |
| Further work | • The nature and scale of planned further work (e.g. 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. |
Exploration at Don Enrique is at an early stage. Drill targets will be delineated once imminent geophysical surveys have been completed and the data assessed. |
