Drill Results

More high-grade drill results for Herencia

45 metres at 1.70% copper

 

Highlights

 

· More high-grade drill results (on top of the recent 91m at 1.42% copper from 19m announced last week), from the Picachos RC drill program, continues to confirm the broad zones of high grade copper mineralisation at shallow depths

· Laboratory assay results returned in recent days include:

Hole PP14022 45m at 1.70% copper from 95m including;

ü 34m at 2.09% copper from 102m

 

Hole PP14027 11m at 1.20% copper from 72m including;

ü 7m at 1.52% copper from 76m

 

· Most holes drilled to date are angled drill holes cutting mineralisation approximately perpendicular to the dip - resulting in most widths announced being close to 'true width'

· Potential for several near surface zones of copper mineralisation with high grades and significant widths that could potentially support open pit type mining operations

· Picachos Project located in close proximity to a number of operating copper processing plants that could potentially provide near-term toll treatment opportunities

· RC drilling program completed and drilling contractor demobilised. A total of 3,540m reverse circulation (RC) metres drilled, with all laboratory results expected by the end of June 2014.

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, backing up those broad, high-grade assay results announced last week (RNS 4 June 2014) which included 91 metres at 1.42% copper from 19m in hole PP14019 (including 60m at 1.94%).

 

 

The most recent significant laboratory assay results include:

o Hole PP14022 45m at 1.70% copper from 95m including

§ 34m at 2.09% copper from 102m

 

o Hole PP14027 3m at 1.06% copper from 56m

11m at 1.20% copper from 72m including

§ 7m at 1.52% copper from 76m

As previously advised, the drill program was designed to test six key areas that could potentially host open pit style mineralisation. The above results come from the 40m Shaft zone adding to those high grade copper assay results recently achieved there (as announced in RNS of 4 June 2014).

The current drill program has now been completed and the drilling contractor demobilised with all remaining assay results expected to be received by the end of this month. In the meantime, the Company's geological team are focused on interpreting the results and preparing a 3D geological model.

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

 

"On the back of 91m at 1.42% copper these new results, especially the outstanding 45m at 1.70% copper from the same area, are extremely pleasing and further supports or belief that we could well be on to a potential winner at Picachos.

The Picachos style of shallow, high-grade and wide mineralisation is not often seen in Chile. This style of mineralisation lends itself well to low-cost open pit mining methods (often aided by a low waste strip ratio). This scenario, together with the regional potential for toll treating copper ore (given the proximity to a number of existing copper processing plants), fits well with our plans to minimise capital requirements at Picachos.

By being inventive and opportunistic, and supported by these continued terrific results, it is my belief we could have something special at Picachos."

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 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.

About Herencia

Herencia Resources plc, is an AIM quoted exploration and development company operating in Chile. In addition to the Picachos Copper Project, the Company has a Joint Venture with OZ Minerals at the Guamanga Project where drilling is scheduled to commence this quarter and it has completed a Feasibility Study in relation to its 70% owned Paguanta Project, a high grade silver-zinc-lead project located in northern Chile. The Company's corporate office is located in Perth and the main technical and management office is located in Santiago, Chile where it has been operating for over eight years.
