Herencia Resources plc (AIM:HER), the Chile-focussed mineral exploration and development Company, is pleased to announce further high-grade copper assay results from drilling at its advanced Picachos Copper Project ("Picachos" or the "Project") in northern Chile, plus significant silver assays from the same program. The results are the final assays from our inaugural 3,540 meter drill program at Picachos.

The company will now analyse all data with the view to establishing a preliminary geological model from which the next stage of the Picachos development will be planned. Given the high number of shallow and high grade intersections seen throughout this program it is possible that the Picachos Project could support multiple open pits to provide operational flexibility - an important consideration in the mine planning process.

The shallow nature of the mineralisation also lends itself to quick and cost effective access to ore.

The most recent assay results include:

Hole PP14020 18m at 1.33% copper and 6.1g/t silver from 60m including;

ü 10m at 2.04% copper and 8.5g/t silver from 66m

Hole PP14021 5m at 1.36% copper and 15g/t silver from 25m; and

18m at 1.0% copper and 7.8g/t silver from 76m including;

ü 10m at 1.68% copper and 10.3g/t silver from 79m

ü 4m at 2.30% copper and 14.8g/t silver from 81m

Hole PP14025 6m at 1.34% copper and 15.8g/t silver from 47m including;

ü 2m at 2.67% copper and 38g/t silver from 50m; and

5m at 1.06% copper and 9.8g/t silver from 77m;

Hole PP14027 11m at 1.18% copper and 5.9g/t silver from 72m including;

ü 7m at 1.53% copper and 7.3g/t silver from 76m

Hole PP14028 20m at 0.89% copper and 8.3g/t silver from 62m including;

ü 3m at 1.41% copper and 15.7g/t silver from 63m

ü 6m at 1.49% copper and 11g/t silver from 75m

Hole PP14017 4m at 1.10% copper and 11g/t silver from 9m;

3m at 1.60% copper and 10.3g/t silver from 41m;

5m at 1.29% copper and 8.4g/t silver from 73m

 

Hole PP14018 15m at 0.89% copper and 7.66g/t silver from 64m including:

ü 4m at 1.67% copper and 13.5g/t silver from 75m

Hole PP14024 9m at 0.97% copper and 5.4g/t silver from 41m

Hole PP14029 17m at 0.80% copper and 3.5g/t silver from 13m including:

ü 5m at 1.16% copper and 6.2g/t silver from 24m

Managing Director, Graeme Sloan, commented on the results above:

 

"These high-grade copper results are a continuation of the great results announced over the last four weeks and clearly demonstrate that Picachos is not a 'one-hole' wonder, but rather a high grade copper project with excellent tonnage potential.

Picachos has already delivered multiple wide, high grade intersections including 91m at 1.42% copper, 45m at 1.70% copper and now 18m at 1.33% copper backed up by numerous additional zones of broad plus 1% copper intercepts, all of which add to the overall picture of what could be a very special project.

These latest results are close to the surface and it is important to note that just about every zone targeted by our drill program achieved shallow high grade copper hits.

In addition to the copper grades we are now seeing silver results coming through from the assay laboratory, which range up to 38g/t. These are significant values as they potentially add to the low-cost theme at Picachos, whereby silver credits may cover a significant percentage of future mining costs.

I believe Picachos can potentially be developed quickly, with a very low capital cost. Any credit from a silver by-product will just lower what we already believe will be a low operating cost environment, given the shallow open pit-able nature of the mineralisation."

About the Picachos Project

The Picachos Project is located approximately 50km south east of the coastal city of La Serena, 8km west of both the existing Andacollo copper-gold project operated by Teck Resources and the mining town of Andacollo (population approximately 10,000 people), and 10km south of the privately owned Tambillos copper mine. The Project is very well positioned for infrastructure with existing high voltage power located approximately 3km east of the Project area and serviced by two all-weather access roads.

Small scale mining is currently being undertaken by private miners via small open pit and underground mining operations. Ore is being trucked to a Chilean government owned processing plant (ENAMI plant) for processing. This mining will continue up until such time as the Option to fully acquire Picachos is exercised (at Herencia's discretion) and is seen by the Company as an excellent mechanism to achieve geological and grade data across many zones of mineralisation.

A review of available data and Herencia's own geological programs has confirmed multiple zones of mineralisation with a combined strike length of over 8km contained within the Project area. In some areas the close relationship of these zones coupled with multiple occurrences of out-cropping wide zones of mineralisation, highlights the excellent potential for large scale open pit mining to take place at Picachos. Historic mining has focused mainly around the high grade structures, however in some areas the mantos have been mined up to 50m wide. Mineralisation generally commences from one to five metres below the surface and appears open at depth.
