Picachos Delivers More High Grade Copper

Picachos Delivers More High Grade Copper

with 117m at 1.14% Cu

Highlights

· Assay results from Stage II drilling continue to provide impressive results at the Picachos Copper Project in Chile

· Diamond hole DD14003 encounters 117m at 1.14% copper - an extraordinary result

· A diamond drill extension (or "tail") to RC hole PP14036 encounters two additional zones of high grade copper at depth

· Both DD14003 and DD-PP14036 highlight the potential for further down dip extensions of the Picachos mineralisation

· Results include:

Hole DD14003 (Diamond) - 117m at 1.14% copper (and 10.2g/t silver) from 182m including:

§ 18m at 1.53% copper (and 12.6g/t silver) from 184m including:

o 9m at 2.02% copper (and 19.7g/t silver) from193m

§ 16m at 1.50% copper (and 13.8g/t silver) from 213m

§ 10m at 1.95% copper (and 21.8g/t silver) from 254m

§ 10m at 2.00% copper (and 17.8g/t silver) from 268m

§ 11m at 2.21% copper (and 20.4g/t silver) from 288m

Hole DD-PP14036 (Diamond tail on RC hole PP14036):

§ 8m at 1.05% copper (and 6.8g/t silver) from 169m

§ 6m at 2.13% copper (and 21.3g/t silver) from 182m

Herencia Resources plc (AIM:HER), the Chile-focussed mineral exploration and development Company, is pleased to advise that following on from recent excellent laboratory assay results from drilling at its advanced Picachos Copper Project ("Picachos" or the "Project"), an exceptional intersection of 117m of plus 1.1% copper has been achieved.

Managing Director, Graeme Sloan, commented on these new results:

 

"This is truly an extraordinary result from diamond drill hole no. 3. It is the best result to date at Picachos and one of the better I have experienced in my career.

What is most promising, these results appear to be linked to earlier DD14001 results which returned multiple wide high grade intercepts including, 31m at 1.87% Cu (incl.23m at 2.32% Cu) and 19m at 1.04% Cu (incl.6m at 1.84% Cu). In addition we intersected two new zones of high grade mineralisation, including a zone of plus 2% copper, in a diamond hole (tail) drilled to extend RC hole PP14036, a great result all round.

The drilling at Picachos is exceeding all our expectations.

The opportunity to develop an open pit mining operation to exploit these large areas of copper mineralisation is now very clear, and our team in Chile have one goal in mind - to be mining copper ore within 12 months - and all for a very low capital outlay."

 A table of significant assay results reported by the laboratory is shown in Appendix 1.

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) where it is processed. 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 and drilling programs have confirmed multiple zones of copper 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.

· All samples assayed by ALS Laboratory Group, Chile/Peru

· Crushing all sample 70% < 2mm;split to 1 Kg; and powdered 85% < 75 µm

· ME ICP41 method or Cu-OG62 ore grade for Cu 0.001-50%

· All widths are downhole widths

· Hole ID co-ordinate grid is WGS84 UTM Zone 19S

 

The QA/QC process used to record the drilling results includes collecting and recording 10kg and 20kg one metre and two metre samples respectively, over the entire length of the drill hole with the one metre samples confined to the mineralised zones and the use of standards, blanks and duplicates. The samples are visually logged by the onsite Company geologists for geology and mineralisation and hand-held XRF ("XRF") samples taken over the mineralised zones. The individual samples are then transported and submitted to an accredited analytical laboratory (ALS) for assaying.
