MERCEDES ELVIRA PROSPECT SAMPLING RETURNS FURTHER HIGH-GRADE COPPER VALUES
Highlights
-
High-grade copper values of up to 3.8 % from new sampling at Elvira
-
Sixteen out of twenty-three samples assayed greater than 1% copper over the magnetic low anomaly
-
New copper-oxide structures identified within porphyry area
-
Pole-dipole IP geophysical survey over Elvira porphyry prospect in progress
Elementos Limited (ASX: ELT) (“Elementos” or the “Company”) is pleased to provide results from the most recent sampling at the Elvira porphyry prospect at Mercedes, northern Chile.
Assay results from 23 rock-chip samples of exposed mineralisation in outcrop and artisanal mine workings has returned high-grade copper values with anomalous gold, silver and molybdenum – see Figure 1 and Table 1. Highlights include:
-
A significant number of new high-angled copper oxide mineralised structures following north-south, east-west and north-west trends;
-
Assays of up to 3.8% copper, 27 g/t silver, 0.42 g/t gold, 64 ppm molybdenum and 220 ppm tungsten;
-
Sixteen of the samples returned copper values over 1%; and
-
The high-grade copper values occur within a magnetic low anomaly, a common geophysical feature of many porphyry deposits in northern Chile.
Widespread copper-oxide rich structures have been identified throughout the footprint of the magnetic low and the transitions to the magnetic highs, indicating the potential to identify near-surface, structurally controlled mineralisation. These structures contain minor credits of molybdenum and tungsten, potentially indicating a high temperature fluid source which could indicate deeper, sulphide mineralisation within the porphyry prospect at Elvira – see Figures 2 and 3.
Detailed mapping and sampling programs are continuing over the near-surface, high-grade oxide targets as well as the porphyry prospect, to aid drill target generation.
The recently completed airborne magnetometry survey and the IP geophysical survey currently underway should provide a rapid indication of the size and depth of the potential porphyry target, as part of the geological evaluation for the identification of drill targets.
