TAMAYA SECOND PHASE SAMPLING IDENTIFIES FURTHER HIGH-GRADE COPPER
Highlights
-
High-grade copper up to 4.57%, with 60% of reconnaissance samples containing over 1% copper, reported from multiple structures
-
Gold and silver anomalies up to 2.21 g/t and 8.4 g/t respectively indicate potential for precious metals mineralisation
-
Program advancing to target definition in preparation for drilling
Elementos Limited (ASX: ELT) (“Elementos” or the “Company”) is pleased to announce the results of the second phase sampling and mapping program at the Tamaya Project, central Chile.
This phase has concentrated on the main Tamaya structural trend that was the primary focus of historic mining activity. Reconnaissance sampling was carried out along six kilometres of the structure that trends north-south through the centre of the project, parallel to the ridge-top of the Cerro Tamaya hill. Seventy-three representative rock-chip and character samples were collected from outcropping structures, veins, historic mine workings and mine waste dumps.
Forty-four of the seventy-three samples returned over 1% copper, up to a maximum of 4.57% (Table 1).
Preliminary interpretations include:
-
The main Tamaya vein is flanked on each side by a number of smaller subparallel structures and is off-set locally by small cross-cutting structures;
-
This main structural trend coincides with a significant linear magnetic high;
-
Gold values were reported from multiple, widely distributed samples with grades up to 2.21 g/t gold;
-
Silver values ranged up to 8.4 g/t, which together with the gold values, demonstrate that a precious metal phase of mineralisation occurred. This appears to coincide with the presence of quartz veinlets cutting through the copper vein structures; and
-
On-going mapping and sampling of the principle mineralised structure has clearly defined over six kilometres of strike length, with some minor off-sets by cross-cutting structures.
The on-going mapping and sampling programs are building a robust model of the geological environment, to be used in drill target generation. A further 124 assay results are pending.

Next Steps
Mapping and geochemical sampling programs are continuing over the historic workings and surface exposures of the multiple structures, veins and systems which host copper mineralisation. This will be followed by a ground-penetrating pole-dipole IP geophysical survey, planned to commence in late May. The aim of this exploration is to aid target definition for drilling (planned for the third quarter 2012, subject to drill rig availability).

COMPETENT PERSON STATEMENT
The information in this report that relates to Exploration Results, Mineral Resources or Ore Reserves is based on information compiled by Mr Alistair Grahame, a member of the Australian Institute of Geoscientists. Mr Grahame is a full-time employee of Elementos Ltd and has sufficient experience which is relevant to the style of mineralisation and type of deposit under consideration and to the activity which it is undertaking to qualify as a Competent Person as defined in the 2004 Edition of the ‘Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves.’ Mr Grahame consents to the inclusion in the report of the matters based on his information in the form and context.
SAMPLE QUALITY CONTROL AND ASSURANCE
Samples were prepared and assayed by ALS Chile (“ALS”), Minerals Division, at their facility in Coquimbo, an ISO9001:2008 certified laboratory. Methods utilised were:
-
Thirty-three element ICP_AES;
-
Samples returning greater than 1.0% copper are assayed using Four Acid Digest and an Atomic Absorption Spectrometer (“AAS”);
-
Gold assay by Fire Assay (30g) and AAS; and
-
Samples returning greater than 1.0 g/t gold are check analysed by ALS using the same method.
