Trinchera Este shows significant grades of Cu & Mo outside of the breccia
EV Resources Limited (ASX: EVR or “EVR”) is pleased to announce the assays from the final three diamond drill holes of the 1H 2024 drill campaign at the Company’s high grade Parag copper-molybdenum-silver project in Peru.
The seven diamond drill holes drilled in the Trinchera Este area have shown that mineralization is not restricted to the polymictic (sulphide) breccia system but also occurs in the surrounding intrusive porphyry and hornfels and adds to our conviction that Parag is a system of potential scale beyond the immediate high grade mineralisation already intersected in drilling within the breccias.
Figure 1: Cross Section along A-A´ looking West. Copper assay values on a 2m interval. For Sections showing Molybdenum and Silver Values see Figures 7 and 8 below.
==> picture [418 x 470] intentionally omitted <==
The initial program of defining the volume and economic potential of the mineralized breccia system will be extended in the next phase of drilling to understand and evaluate economic mineralization outside the breccia and explore at depth for the presence of a larger porphyry-type system.

2 LME Closing Prices as at 5th July 2024 (www.lme.com) and www.kitco.com
- A review of silver in previous drill holes is underway and will be released to the market in due course.
Hugh Callaghan, Managing Director of EVR said “The successful drill campaign at Trinchera Este highlighted high grade copper-molybdenum-silver mineraliszation in both the polymictic breccia and in the surrounding intrusive porphyry and hornfels – similar to the analysis of old drill core at the Paylacocha 1 breccia system nearly 1200 metres to the West. This supports our view that the Parag porphyry system is potentially large. The geophysics programme commencing this week will help us understand the system better and guide further drilling programmes.”
Next Step
A programme of magnetometry and Induced Polarisation studies commences this week at Parag and should provide EVR with a better understanding of the structure, geometry and scale of the system.

Geochemistry
The initial drilling program executed at the Parag Cu-Mo-Ag project between February and March 2024 initially focused on evaluating the Trinchera Este area.
Values of Cu and Mo only were reported in previous press reports. This announcement includes an analysis of the presence of Silver (Ag) content that was not documented in previous press releases.
Silver (Ag) contents accompany the intercepts mineralized with Cu and Mo and appear consistent in their spatial distribution in the seven holes and 1980 meters drilled so far. The Ag mineralization accompanying the Cu and Mo contents is concentrated in areas of strong silicification and better distributed in mineralized breccia. However, it also occurs in the host rock, including felsic intrusives and hornfels.
In this first phase of exploration, diamond drilling has established that mineralization in Trinchera Este is located in the intensely altered polymictic breccia. The dominant alteration is silica, quartz-sericite, chlorite-sericite, together with the presence of carbonates and local chlorite superimposed on biotite.
Furthermore, these drill assay results demonstrate that Cu-Mo-Ag mineralization occurs from the surface or close to the surface and confirms that mineralization extends laterally outside the mineralized breccia. High values of Cu correlate with increased Ag and Mo values.
The diamond drill holes reported in this, and previous press announcements are considered encouraging and of great value for understanding mineralization behaviour inside and outside the mineralized breccia system. Future work, including geophysical surveys, will assist in optimizing future (imminent) drilling programs.
Progress at other EV Resources Properties
-
The company plans to drill a 2,000 metre programme at Don Enrique in the second half of the year.
-
A review of copper assays at the polymetallic Khartoum project in Queensland will be undertaken to supplement recent identification of high grade gallium samples and add to data obtained from drilling and sampling of the tin and tungsten mineralization at the project.
