DIVISORIA PORPHYRY-RELATED MINERALISATION EXTENDED

Highlights

  • Disseminated gold and silver anomalies extended within the chargeability anomaly at the Divisoria porphyry prospect

  • New high-grade gold and silver veins and breccias identified

  • The potential of the Santo Domingo mineralised system continues to grow with new high grade structures and the expanding porphyry system

Elementos Limited (ASX: ELT) (“Elementos” or the “Company”) is pleased to report new exploration advances at the Divisoria prospect at the Santo Domingo project, Argentina.

Follow-up mapping and sampling of targets identified by the recent geophysics successfully identified alteration and geochemical anomalies that appear to represent porphyry mineralisation in a number of areas not previously recognised.

Highlights from both porphyry-style veinlets and disseminated sulphides, and late stage cross-cutting veins and breccias within the geophysical anomaly include:

These samples are all from new localities and represent a significant expansion of the previously recognised mineralisation zone. Recent flooding has exposed new outcrops in the gully bottoms, highlighting the potential for significant new discoveries in the poorly exposed area.

Significantly, a new occurrence of intermediate sulphidation epithermal mineralisation (ISE), the first at Divisoria, has been identified, and is situated two kilometres from the existing ISE prospects. This implies a far wider potential distribution than realised to date.

New Disseminated Mineralisation at the Divisoria Prospect

Follow-up mapping and sampling at the Divisoria porphyry prospect, targeting anomalies highlighted by the 2011 Pole-Dipole Induced Polarisation (“PDIP”) and Audio Magneto Telluric (“AMT”) geophysics programs, has significantly expanded the previously identified disseminated and stockwork mineralisation on surface, within the footprint of the geophysical anomalies.

Additionally, flash-floods during summer storms earlier in the year have opened new outcrops along the streambeds, exposing new areas of alteration and mineralisation, which is significant since it highlights the potential to extend the mineralised system within the area already studied.

New Epithermal Structures Identified at Divisoria

Narrow, sheeted veinlets of high-grade mineralisation in a strongly altered north-east trending shear-zone, similar to the ISE mineralisation at Yvette and El Arriero West, have been discovered 250 metres north of the Divisoria porphyry prospect. These are important as they are located on the rim of the circular feature that appears to encompass most of the strongest porphyry-style mineralisation, similar to the occurrences recently identified in El Arriero West, but three kilometres from the nearest location of a similar style. Localised sampling returned:

o 0.2 metres at 43.1 g/t gold and 19 g/t silver.

Localised trenching and representative sampling are required to test this prospect.

New High-Grade Structures Identified at Divisoria

Several narrow, high-grade structures have been discovered cross-cutting the earlier porphyry mineralisation, within the metamorphic host rocks. These structures predominantly trend to the north-west, with a lesser set to the north-east.

The narrow, high-grade structures are characterised as follows:

  • Silicified breccias with oxide matrix, mostly crosscutting early porphyry mineralisation:

  • 0.8 metres at 7.4 g/t gold and 84 g/t silver (Figure 1).

This is on the same trend where previous sampling returned:

  • 3.22 g/t gold, 50 metres to the south.

  • Narrow quartz veins (gold–silver plus polymetallic) cross-cutting both porphyry mineralisation and metamorphic basement, where previous sampling returned values up to:

  • 0.2 metres at 5.6 g/t gold;

  • 0.3 metres at 38.8 g/t gold; and

  • 0.2 metres at 4.8 g/t gold.

Although not stand-alone targets, these have the potential to increase the overall grade of the deposit by intercepting blind structures at depth.

Figure 1: North-west structure (between dotted red lines), which returned 0.8 metres at 7.4 g/t gold and 84 g/t silver. The structure is hosted in phyllic altered dacite porphyry. A previous sample in phyllic altered host rock returned about 0.27 g/t gold.

Exploration Potential

The Santo Domingo project exhibits two distinct styles of mineralisation that need to be further tested for their economic potential:

  • low grade–high tonnage, gold–copper disseminated porphyry mineralisation; and

  • peripheral, high grade–low tonnage gold-silver polymetallic narrow structures.

The geology appears typical of Andean-style porphyry emplacement, with the addition of the shear-hosted mineralisation around the periphery of the system, which has now been recognised in two newly exposed localities. The main targettypes are:

  • Gold-copper porphyry systems at:

  • Divisoria - the larger and most prospective of the porphyry targets;

  • El Arriero and El Arriero Extension - high-level expression of a porphyry system; and

  • Alunita - largely untested prospect with intense alteration.

  • High-grade, gold, silver and base-metal shear zones at:

  • Yvette and Yvette Norte - intersecting trends of mineralised shearzones; and

  • The newly discovered El Arriero West and Divisoria North prospects.

At the Divisoria gold-copper porphyry prospect, disseminated sulphides enclosed within the phyllic alteration assemblage correlate strongly with the chargeability anomaly from surface to beyond 300 metres depth.

SAMPLE QUALITY CONTROL AND ASSURANCE

Gold assay results presented above are finals and have been calculated using a 0.5 g/t gold cut-off grade. Gold intervals are weighted averages of sample length multiplied by gold grade.

Samples were prepared at the Acme Analytical Laboratories (“AcmeLabs”) preparation facility in Mendoza, Argentina and assayed by fire assay (50 gram charge) at the AcmeLabs laboratory in Chile and for ICP-MS 32 elements (15 grams charge) at the AcmeLabs laboratory in Vancouver, all ISO-9001:2000 certified laboratories. Samples returning greater than 10 g/t gold and/or greater than 100 g/t silver are assayed using gravimetric analyses. Samples returning greater than 1% lead and / or greater than 1% zinc are assayed using aqua regia digestion ore grade / AAS.
