TORONTO, May 7, 2013 /CNW/ - Patagonia Gold Plc (AIM:
PGD, TSX: PAT) ("Patagonia Gold" or "the Company") today is
pleased to provide a progress update for its Lomada de Leiva,
Cap-Oeste/COSE and La Manchuria projects in Santa Cruz province, Argentina.
Lomada de Leiva
- Preparation works for the 200,000 tonne expansion of the
existing trial heap leach pad were completed in late March 2013 with loading of mineralised material,
irrigation and production of gold in progress.
- Construction of the first stage of the main heap leach pad
remains on schedule for completion in late Q2 2013. The PVC
membrane lining of the drainage dam and buttress sections is now in
place with pipework installation underway.
- Patagonia Gold's mining fleet has been delivered to site and
commissioned. Operator training and demobilisation of rented gear
is underway, with all contractor equipment scheduled to be offsite
by the end of May 2013.
Cap-Oeste/COSE
- Drilling in the structural corridor between the Cap-Oeste
and COSE deposits continues to intersect wide zones of gold-silver
mineralisation with drill-hole CSE-091 intersecting 66.6 metres at
2.04 grams per tonne (g/t) gold and 36.18 g/t silver.
- COSE resource update to include the newly identified
mineralisation scheduled to commence in early Q3 2013 with
completion in early Q4 2013.
- Pre-feasibility study on the Cap-Oeste deposit is set to
commence in May 2013, led by
Newfields Inc. of Reno,
Nevada.
La Manchuria
- Drilling has recommenced at La Manchuria, with 4,000 metres
of extension and exploration drilling scheduled for completion in
Q2 2013.
- The La Manchuria deposit is currently being re-evaluated as
a potential bulk tonnage heap leach target that will incorporate
mineralisation not previously included in the model.
"With the Lomada project funded to completion and set to provide
free cash flow in the second half of 2013, Patagonia Gold can now
focus on expanding its significant resource base of 1.88 million
ounces of gold equivalent, concentrating on the highly prospective,
high grade Cap-Oeste/COSE and La Manchuria deposits," said
Bill Humphries, CEO of Patagonia
Gold.
Photographs of the progress at Lomada and Cap-Oeste will be
posted on the Company's website, www.patagoniagold.com.
LOMADA DE LEIVA
The Lomada de Leiva project is located approximately 40
kilometres southeast of the town of Perito Moreno in the province
of Santa Cruz, within the
Company's La Paloma property block, covering over 44 square
kilometres.
Gold production continues with the mining, loading and
irrigation of mineralised material onto the expanded trial heap
leach pad.
Construction of the fully permitted Lomada main heap leach
project is well advanced and on target to achieve full 'nameplate'
production of 21,000 ounces of gold per annum in late Q2 2013. The
company recently received a permit, issued by the national
authorising body RENAR, to store explosives onsite, which will
substantially increase mining capacity and reduce costs.
Construction of the explosives magazine was completed in Q1
2013.
Targeted mine production of 65,000 tonnes of mineralised
material per month is scheduled to be achieved by June 2013, which is expected to coincide with the
completion of the main pad area. Mine office facilities are now
onsite and installed and a 40-person mine camp has also been
constructed. The mine camp, to be commissioned by late May, will
increase onsite personnel availability and reduce administration,
travel and lodging costs.
CAP-OESTE/COSE
The El Tranquilo property block, covering approximately 80,000
hectares, contains Patagonia Gold's flagship Cap-Oeste project,
together with the COSE bonanza gold and silver deposit and numerous
other prospects including Monte
Leon.
Ten diamond core HQ drill holes totalling 2,475 metres have been
completed so far this year, targeting the wide mineralised area,
previously identified by exploration drilling in 2012 (ref. news
release 5 July 2012), along the
Bonanza-COSE fault between the Cap-Oeste and COSE deposits. To
date, the 1.5 kilometres of strike length has been only partially
been tested. Further drilling will be designed once all results
have been received and the first phase of a new geological resource
model has been completed.
COSE mineralised intersections include:

Patagonia Gold is assessing the possibility of including COSE in
the Cap-Oeste pre-feasibility study. A recalculation and estimation
of the COSE resource will need to be completed as the first step of
the pre-feasibility study, after which the combined compliant
resources of Cap-Oeste and COSE will be incorporated into the
preliminary evaluation. Newfields Inc. of Reno, Nevada will lead the pre-feasibility
team along with mining consultant AMEC and potentially another
third party to oversee plant and metallurgical process design and
costing. Further updates will be provided as the pre-feasibility
study proceeds.
LA MANCHURIA
The La Manchuria project is located approximately 44 kilometres
southeast of the Cap-Oeste and COSE deposits and represents a large
system of low sulphidation style vein hosted gold-silver (Au-Ag)
mineralisation that outcrops at surface. To date, the Company has
completed 20,993 metres of diamond and reverse circulation drilling
on this project. Patagonia Gold reported the following Canadian
National Instrument (NI) 43-101 compliant resource in September 2010:

Thomas C. Stubens, M.A.Sc.,
P.Eng., a Senior Geologist with Micon International Limited and a
Qualified Person as defined in Canadian National Instrument 43-101,
was the author of the report entitled "Technical Report on the
Mineral Resources of the La Manchuria Project, Santa Cruz Province, Argentina", prepared for Patagonia Gold
SA, dated September 15, 2010.
Management believes that significant potential exists to
substantially grow the resource base by changing the mineralisation
focus from the thin, discontinuous high grade vein hosted model to
a low grade bulk tonnage target. Preliminary re-evaluation work is
underway. Should this study provide positive results, an updated
43-101 compliant resource will be prepared.
Drilling is currently in progress and will concentrate on
extending the mineralised envelope on the Manchuria deposit and
testing targets at Manchuria East and further to the northeast and
southeast, where no drilling has previously been completed.
Drilling will also follow up on the excellent trenching results in
Manchuria East, including TR-EZ S07 reporting 12 metres @ 2.97 g/t
gold and TR-EZ S09 2.5 metres @ 11.98 g/t gold. Both of these
trenches intersect an outcropping vein structure with a strike
extent of in excess of 300 metres.
Geochemical and geophysical programs will also be undertaken
during the second half of 2013 on both the La Manchuria property
and the recently incorporated Manchuria South property, which was
obtained through the 2011 PGSA joint venture arrangement between
the Company and Fomicruz, the Santa
Cruz provincial mining company. Manchuria South contains
mineralised occurrences previously delineated by Fomicruz.
