EV Resources Limited (ASX: EVR) (“ EVR ” or the “ Company ”) is pleased to announce it has reached agreement to acquire a 70% share of the Parag Copper-Molybdenum project in Peru. This transaction secures EVR an advanced copper project with substantial historical drilling, and a Mining Licence that will position EVR’s growing copper portfolio as the focal point of the Company’s activities.
The Parag Project totals 1399 hectares and is located 145km north of Lima in the province of Huaura (Figure 1). It is accessed by sealed roads as far as Sayán, unsealed roads to Churin, and the final 75km on dirt tracks. The overall distance by road from Lima is 350 km, with travel time of about eight and a half hours. The terrain consists of open hills, above the tree line, with an average elevation of 4,700m.
The project was explored in two phases, first in the 1980s culminating in 8,300m of drilling and again in 2011 with an additional 10,170m of drilling. An extensive area anomalous in Copper and Molybdenum has been defined by channel sampling. Historically, attention was focused

on several mineralised breccias (Figure 2) although other lithologies on site are mineralised, notably Hornfels and Dacite Porphyry.
Historical drilling suggests the presence of an economic copper-molybdenum orebody, with significant value contributed by the molybdenum, currently more than five times the price of copper. Minor quantities of silver and gold have been recorded in most drill holes. EVR’s plan is to move rapidly towards defining a shallow resource on the breccias whilst developing a deeper, longer-term, porphyry copper target.

Figure 2: Panoramic view of the Parag Copper-Molybdenum Project area, with the key Breccia orebodies shown in red dots.
The project was initially explored by the Gubbins family in the 1980s. They undertook mapping and took 196 grab samples for geochemistry. Gubbins drilled 55 diamond holes for a total of 8,293m. The holes were relatively shallow, the deepest being 333.90m. There are references in their files to IP work done at this time, but this data is not available.
Figure 3 shows the target areas developed by the Gubbins geology team, with the collars from their drill program. Essentially, they correspond to outcropping breccia bodies and were mostly drilled with short, vertical, holes. In contrast to the later Orion programme, the Gubbins programme focused on high grade breccia targets only.

Orión was at the times exploring a more extensive tenement package with ground to the west which is now held by Vale and Newmont. They defined an additional “Porphyry” or “Pórfido” target area (Figure 4).
The ground reverted to Geoandina Minerals in 2011. During that time, GeoAndina secured a mining right to extract 1050 tonnes per day from the licence.
Breccias and Mineralisation
Mineralised breccias outcrop over an area of approximately 1.7km by 1.5km in the southern corner of the Viento Licence. Three separate types of breccias have been identified. The most significant are tourmaline-pyrite breccias. These are “generally polymictic breccias with subangular to subrounded clasts of hornfels, porphyritic intrusives with quartz eyes up to 4mm in diameter (quartz porphyry), strongly altered to quartz-sericite and clasts of possible tonalitic medium-grain intrusion also strongly altered to quartz-sericite, agglutinated in a tourmalinesilica cement with development of blackish tourmaline microcrystals. Presence of copper sulfides in the tourmaline mass, predominantly chalcopyrite and traces of bornite and molybdenite in traces, with moderate presence of fine pyrite. The quartz porphyry fragments show the presence of copper sulphides, chalcopyrite, and traces of bornite” (Lemuz, 2023).
Another group of breccias are mapped as “Phreatomagmatic Bx”. These are “Matrixsupported breccia; medium grain igneous cement with strong alteration to quartz-sericite, predominantly greenish sericite. It presents fragments of quartz porphyry, fragments altered to quartz-sericite, whitish sericite, possible medium-grain granodiorite, and the scarce presence of metamorphic rocks (possible hornfels). The shape of the fragments is generally subangular to subrounded. Traces of copper sulfides such as chalcopyrite and bornite, and pyrite.” (Lemuz, 2023).

Figure 4: Breccia hand specimens referenced to Orion mapping.
A third class of breccia, restricted to a single outcrop within the claim area, is mapped as “polymictic bx” by Orión. The outcrop is described as “Polimictic matrix-supported breccia, a matrix cemented by silica, presents angular fragments of quartzite and little sandstone. The sedimentary rock fragments show millimeter veinlets of granular quartz, occasionally with fine dark mineral in the central part and subrounded fragments of possible tonalite altered to moderate quartz-sericite.” (Lemuz, 2023).
The three breccia classes were validated against the Orión mapping in a field visit by EVR’s Head of Exploration in Peru (Gonzalo Lemuz) (Figure 4).
Orión conducted extensive channel sampling of outcrops (4,665 samples in total). The following points are noted:
-
The mapped breccia bodies are not uniformly mineralised.
-
Copper and molybdenum mineralisation is sometimes, but not always, spatially coincident.
-
Apart from the breccias, copper can be present in hornfels and Qz monzonite.
-
Apart from the breccias, molybdenum can be present in Dacite Porphyry 2.

Exploration and Next Steps
EVR’s team is particularly interested in the presence of the tourmaline breccias, of clasts of mineralised porphyry with chalcopyrite and traces of bornite. This is direct evidence of a mineralised porphyry system at depth and underpins our strategy of moving quickly towards a shallow resource on the breccias whilst developing a deeper, longer-term, porphyry copper target.
EVR will spend the due diligence period accumulating additional data and hopes to find the data from previous Geophysics programmes on the project area, plus additional data from the Gubbins drilling. Core will be relogged, and an initial 5,000m drilling campaign will be prepared. It is intended that this programme will seek to replicate the old Gubbins programme that focused on high grade breccia targets, and which (when supplemented by the later Orion drilling) provided historic, non-JORC resource estimates.
Transaction Details
EVR has reached agreement with GeoAndina Minerals for the acquisition of a 70% shareholding in the Parag project which will be placed into a newly established company. EVR will pay US$20,000 for a 3-month exclusivity agreement while due diligence is conducted.
At the conclusion of due diligence and confirmation EVR intends to proceed, the parties will enter into a Definitive Agreement that includes the following terms:
-
EVR will make a cash payment of US$150,000 to GeoAndina on signing the Definitive Agreement.
-
An amount of US$50,000 per quarter is payable to GeoAndina until the mine achieves first production.
-
GeoAndina Minerals will have a free carried interest to the point of Readiness to Mine (Bankable Feasibility Study including permitting), at which point GeoAndina may elect to fund its 30% share of project capital.
-
If GeoAndina elects not to fund its 30% shareholding, then it can convert its 30% holding to a non-dilutive 12% carried interest in the project once a commercial production rate is reached, of 3000 tonnes per day of ore mined and milled over a 60day period.
-
EVR has the ability to terminate the agreement at its sole discretion.
-
The Definitive Agreement will be subject to any regulatory and corporate approvals.

| 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. •Geological logging is of an adequate standard. Lithology, alteration, nature and intensity of veining, and description of breccia clasts and a graphic log are available. •The logging is of a sufficient standard to support the construction of a geological model. •All of the holes are logged. •Logging is qualitative. Core photography is believed to exist but has not yet been located. |

| 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. •Detailed reports of the sampling procedures are not available. A summary QAQC report for the 21 DDH drilled by Orión presents control charts for standards, duplicates and blanks for gold. The author has prepared similar charts for Cu and Mo. •The sampling approach is standard and adequate for an early stage project. •Overall QAQC samples are 12.5% of thoal. Standards and blanks are within tolerance for Cu and Au. •The field duplicates were taken wrongly, using quarter core when the rest of the samples are half core. This will cause an error factor of 1.4 in the calculated precision. Even taking this factor into account, 2σ precision for Cu is around 23% @ 0.2% Cu and for Mo is around 27% at 0.1% Mo. These are high values for base metals and suggest that the sample mass is too small. Future drilling should be at least HQ and preferably PQ diameter. |

| 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 •Both the outcrop channel samples and the half-core drill samples were assayed at ALS Lima, an ISO-certified laboratory.
