TAMAYA SAMPLING CONTINUES TO IDENTIFY NEW HIGH-GRADE COPPER STRUCTURES
Highlights
-
High-grade copper up to 6.0%, with gold to 2.4 g/t in multiple new structures
-
New sampling extends strike length of the main Tamaya structure and identifies a number of parallel and cross cutting structures
-
Primary focus to continue testing potential extensions of the known structures and detailed in-fill channel sampling of the main structure to establish drill targets
Elementos Limited (ASX: ELT) (“Elementos” or the “Company”) is pleased to announce the results of a further fifty reconnaissance samples from the Tamaya Project, central Chile.
The aim of the new sampling program was to identify new structures and structure extensions in areas with no previous exploration. The preliminary interpretations of the new sample results (Table 1) include:
-
The high-grade copper mineralisation in the main Tamaya structure has now been extended to four kilometres in a north-south direction;
-
Copper and gold have been identified in a number of new structures that are both parallel-to and cross-cutting the main Tamaya structure;
-
The new structures are returning copper grades comparable to those from the main Tamaya structure;
-
Coarse gold, up to 2.41 g/t, is present in conjunction with the copper in all of the new structures; and
-
Many of the copper and gold zones coincide with strong linear magnetic highs, implying strong, deep structures.
On-going exploration is focused on:
-
Detailed channel sampling and localised mapping of the main structures to define the best targets for the first phase of drilling;
-
Follow-up mapping and sampling of the additional structures identified to date; and
-
Identifying new structures and other styles of mineralisation within the 7,000 hectare property package.

New Sample Results
Fifty samples were collected from outcropping structures, veins, historic mine workings and mine-proximal waste dumps during the reconnaissance survey of areas with no previous exploration.
Sampling on the main Tamaya structure in the southern and northern one kilometre sections of the principle structure has returned more high copper grades, extending the previously reported mineralisation along a continuous four kilometre north-south trend.
A number of new structures have been identified parallel to the main Tamaya structure. The new northern target is a 550 metre long structure, up to 3 metres wide, with copper values up to 1.13% and gold up to 0.33 g/t. The structure remains open to the north and south.
Three main north-south trending structures have now been identified, which are intersected by several lesser, transverse and perpendicular structures. Each structure consists of clearly defined lenses of hydrothermal breccias and stockworks of silicasulphide veinlets cutting the igneous wallrocks. There is a strong spatial correlation between the copper and gold in the structures, as depicted in Figures 1 and 2, although the gold tends to be coarse in nature.
The new structures are returning copper grades comparable to those from the main Tamaya structure. Some of these areas have only small-scale historic workings, highlighting the potential for identifying new structures or extensions that are blind on the surface.
On-going Exploration Activities
Detailed continuous channel sampling and localised fine-scale mapping programs are underway over the principle targets identified to date. The in-fill sampling will assist with better understanding the copper grade distributions across the width of the structures, as well as the genesis of the gold mineralisation within the system. The results will provide more detailed information for drill targeting.
Further mapping and sampling of the new structures identified in the current program and identifying new structures is also underway.
A further 110 sample results are at the laboratory.

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 Limited 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 Adsorption 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.
