ASX ANNOUNCEMENT 20[th] May 2024
EVR to unlock district-scale potential of its high-grade Parag copper-molybdenum project following drill success.
Highlights:
-
Hole APG-006 at Parag extends the known mineralization and dimensions of the Trinchera Este breccia and confirms growing width and length of the structure.
-
Intercepted mineralized porphyry shown to be in contact with breccia, resulting in a significant reappraisal of the Parag breccia-porphyry model.
-
Trinchera Este is the smallest of the 6 previously drilled breccia outcrops and represents a fraction of the overall mineralisation over a strike of up to 1200 metres and width of up to 500 metres.
-
Current drill results are consistent with historical exploration work at Parag that recorded mineralization across all breccias.
-
Hole APG-DDH-006 assayed 218m (metres) at 0.30% Cu and 0.10% Mo from 0m.
-
This includes intersections of:
-
186m grading 0.30% Cu and 0.20% Mo from 0m to 186m.
-
122m grading 0.40% Cu and 0.20% Mo from 0m to 122m.
-
56m grading 0.50% Cu and 0.20% Mo from 0m to 56m.
-
30m grading 0.60% Cu and 0.30% Mo from 0m to 30m.
-
-
Moly and copper prices have risen to:
-
US$48,061/tonne for Mo (Molybdenum) (US$21.80/lb)
-
US$10,114/tonne for Cu (Copper) (US$4.59/lb)
-
Molybdenum trades at a price 4.75x the price of copper demonstrating the high value Molybdenum by product.[1]
EV Resources Limited (ASX: EVR or “EVR”) is pleased to confirm the extension to the northwest of the Trinchera Este breccia with a new hole ( APG-DDH-006 ) at the high grade Parag copper-molybdenum project (70% EVR) in Peru. Significantly, the hole is the third angled hole drilled at Trinchera Este to record lengthy high grade CopperMolybdenum results in the breccia, and then intercept mineralized porphyrtic intrusive.

The results of this hole, the fourth from this current seven hole (1980 metre) campaign, extends the footprint of the Trinchera Este breccia to the northwest. The hole intersects the mineralized breccia from the surface to 125 meters depth where it makes contact with a porphyritic andesite body.
Additionally, laboratory assay values confirm mineralization in both lithological units.
Mr. Callaghan said “ Mineralization in both the breccia and adjacent porphyritic intrusions at Parag requires us to rethink our approach after similar intercepts in holes APG 002, and APG 003 – and then nearly 1000 metres to the West at drilling in the Paylacocha 1 breccia”.
This is a major development for EVR and we are now focused on reevaluating the prospectivity of a project with an expansive breccia system much closer to porphyry hosted mineralization than we previously envisaged . Following the successful drill campaign, we have committed to a reappraisal of the geological model, taking into account the potential increase in scale of Parag. This work also includes targeting delivery of a Q3 Exploration Target for the project .”
Hole APG-DDH-006 stopped in mineralization, and is the third angled hole drilled at Trinchera Este to record lengthy high grade Copper-Molybdenum results in the breccia, and then intercept mineralized porphyrtic intrusive. Each previous angled hole (APG – DDH – 002/3) has extended the dimensions of the Trinchera Este breccia which, notably, is the smallest of the six previously drilled structures. ( See Figure 1 )
Trinchera Este: The Smallest of six previously drilled breccia outcrops
Drilling, mapping, and sampling to date have established mineralization at Parag in breccia and porphyry, over a 1200 metre strike and a typical width of up to 500 metres – although the distance from the Parag Oeste breccia outcrop to Paylacocha II is 1500metres.
The confirmation of mineralization, in both breccia and adjacent porphyritic intrusions is a significant development for the Parag project, indicating that breccia hosted mineralization extends into adjacent porphyritic intrusions.
This requires a significant reappraisal of the geological model and the potential scale of the Parag project. EVR has previously explained that 18,470 metres of diamond drilling (76 holes) has been conducted at Parag prior to EVR’s investment. Six breccia outcrops have previously been drilled and named – and Trinchera Este is by far the smallest of these outcrops. ( See Figure 1)
The mineralized zone at Parag extends over a considerable strike within which Trinchera Este represents one of the smallest outcrops – albeit one we considered geologically important in the search for a mineralized porphyry system of significant scale.

The mineralized breccia of Trinchera Este
The maiden EVR drill campaign has focused only on drilling from 2 separate platforms at the Trinchera Este breccia, situated at the eastern end of the area – it is located 1070 meters from the largest of the outcropping breccia (Pailacocha I) at the westsouthwest end. Figure 1 above demonstrates the extent of this mineralized zone which offers potential for significant scale.
Figure 2: Trinchera Este Breccia – The Smallest of 6 Previously drilled Breccias at Parag
==> picture [511 x 389] intentionally omitted <==
The mineralized breccia that is exposed on the surface covers an area of approximately 90 to 100 hectares. Minor breccias occur towards the north and east of this area, but they are not included in the current phase of exploration. The mineralized breccia of Trinchera Este is characterized by quartz-sericite-chlorite- and later carbonate alteration. It contains mineralization of chalcopyrite, molybdenite, and pyrite, with sporadic zinc and lead towards the surface.
Laboratory results show the presence of silver Copper, and molybdenum mineralization is associated with porphyry type A and B veins, sulfide veins, dissemination, breccia matrix, and filling open spaces.
The breccia in Trinchera East is mostly clast-supported, matrix-supported towards the central part and in-depth, and generally polymictic. Clasts consist of fragments of hornfels, porphyritic andesitic, and felsic intrusive, the latter sometime displaying vein stockwork. Most of the clasts are affected by strong silicification and quartz-sericite alteration. Quartz-sericite-chlorite generally affects the matrix.
The mineralization in the intrusive body is characterized by the presence of dissemination of chalcopyrite and molybdenite, tourmaline millimetre veinlets with copper sulfides, and traces of molybdenum sulfides; pyrite is present in most of the andesite porphyry intrusive body until the end of the hole as traces and eventually reaching 1%. Quartz-sericite-chlorite alteration and patches of retrograde chlorite alteration occur after secondary biotite.
