TAMAYA INDUCED POLARISATION GEOPHYSICS PROGRAM COMMENCES
Elementos Limited (ASX: ELT) (“Elementos” or the “Company”) is pleased to announce the second phase geophysical survey at the Tamaya Project, central Chile, has commenced.
The Induced Polarisation Pole-dipole (“IPPD”) survey comprises approximately six east-west lines totalling up to 36 line-kilometres – see Figure 1. The IPPD survey will test for two styles of mineralisation:
-
Porphyry mineralisation in the eastern sector as indicated by the encouraging results of the recent mapping, sampling and ground-magnetometry survey; and
-
Structurally related mineralisation in the three main north-south structural trends, including the main vein that was historically mined for high-grade copper (sulphide) mineralisation.
Porphyry Target
The ground-magnetometry survey completed in April 2012 outlined a large magnetic anomaly (Figure 2) that is related with porphyry mineralisation in the eastern sector of the property. The IPPD survey will test for chargeability anomalies (the presence of potential sulphide mineralisation related to the porphyry) within the magnetic anomaly.
Mapping has identified evidence of potential porphyry related mineralisation similar to that at the Carmen de Andocollo mine, 40 kilometres to the north, and at the Llahuin deposit, 85 kilometres to the south, which lie on the same major structural trend as Tamaya, including:
-
Porphyry clasts with disseminated mineralisation within breccia structures in the Eastern zone;
-
Strong potassic alteration in association with the high-grade mineralisation in structures in the Eastern and Central zones, grading to moderate in the Northern and Tortolas prospects;
-
Multiple porphyry mineralisation related features, including:
-
Calcite-sulphide veining with very high-grade copper mineralisation;
-
Phreatomagmatic breccias, including a magnetite rich matrix and minor copper mineralisation in the matrix and as clasts;
-
Silica-sulphide breccia, veinlets and stockwork with 2% to 7% copper;
-
Tourmaline breccias with minor disseminated mineralisation in the matrix; and
-
“A-type” texture veinlets and stockworking in the Eastern, Central and Tortolas prospects with calcite, silica or magnetite-specularite fill.

Structurally Related Mineralisation
A number of close-spaced IP lines will be run across the structures at Central and Tortolas. The aim of this survey is to identify:
-
Depth, approximate dip angles and strike extensions of the known highgrade copper structures identified on the surface, and blind structures at depth; and
-
Potential zones of sulphide mineralisation (chargeability highs) in the broad shear and breccia structures that host the main veins.
IPPD Survey
The aim of the survey, which is capable of penetrating to a depth of at least 500 to 600 metres, is to identify anomalies that may represent Carmen de Andacollo and Llahuin-style porphyry mineralisation. The survey will also test the depth potential of the multiplicity of mineralised veins and structures that have been identified at surface.
The information obtained from the survey will be used to refine the drill target selection, especially related to the evaluation of the porphyry potential, in the drilling program planned for the fourth quarter 2012.
