Ormonde Mining plc
("Ormonde" or "the Company")
Antofagasta opt out of La Zarza Agreement
The Board of Ormonde provides an update on activities in
connection with the option agreement (the "Option") with
Antofagasta Minerals S.A. ("Antofagasta").
Following the recent completion of exploration programmes on the
four new investigation permits and the assessment by Antofagasta of
the resultant data, Antofagasta has now informed the Company it
considers that a deposit of sufficient size and scale to meet
Antofagasta's requirements does not currently exist at La Zarza and
therefore it has elected not to fund further activities at La Zarza
and to cease its Option. Accordingly Antofagasta has not earned any
interest in the La Zarza project or the surrounding investigation
permits.
In October 2009, Ormonde entered into an option agreement with
Antofagasta to explore for additional copper resources on the La
Zarza Copper Project, whereby Antofagasta could earn an initial 51%
interest in the La Zarza permit area by spending US$7 million on
exploration activities over a three year period. Activities during
2009 and 2010 were focussed on the La Zarza deposit and results
were reported in September 2010. Based on work to that point,
including geophysics, drilling and a new structural interpretation,
a preliminary non-JORC compliant global mineral resource of 61Mt
grading 0.8% Cu, 0.9% g/t Au, 0.6% Pb, 2.0% Zn and 5.7 g/t Ag, was
estimated.
The option agreement was subsequently amended in April 2011 to
cover four additional permit areas around La Zarza with the earn-in
period extended to 2015. A budget of US$1.3 million was approved
and funded by Antofagasta at this time for the exploration
programme now completed.
Main Results of Exploration Programmes on the Four New
Investigation Permits
-- Detailed gravity and airborne electromagnetic surveys were carried out over the permit areas
-- Diamond drilling of several target areas has been completed
with a total of 3,048 metres drilled on eight targets, principally
defined by a combination of gravity, airborne EM and geology
-- Drilling in hole UC002 intersected altered and brecciated
volcanics over an interval of 147 metres, with pyrite
mineralisation throughout but most intensely developed in the upper
40 metres. Although relatively weak base metal and gold values were
returned, the style and vertical extent of the mineralisation is
that of a stockwork which is commonly associated with mineral
deposits in this area.
Kerr Anderson, Ormonde's Managing Director, said:
"Although Antofagasta has taken the decision to opt out of the
agreement, it is understood to be principally based upon the
group's corporate requirements with regards to minimum deposit size
and scale at La Zarza. The programmes completed in the past year
have provided further important information and results, including
the mineralisation discovered in hole UC002, which will be valuable
in the assessment by Ormonde of the potential for further copper
resources. We will provide further information on our deliberations
in due course."
Detail
Four investigation permits (comprising a total area of some 95
square kilometres), covering the strike extension of the La Zarza
system and controlling structures, were awarded by the provincial
mining authorities to Ormonde's subsidiary Ormonde Espana SL in
August 2011, and these were included in the Option with
Antofagasta, with work programmes on these permits funded by
Antofagasta. The following work programmes were completed:
-- 1,039 gravity stations on a 400 x 50m grid over the permit area
-- 1,031 line kilometres of airborne electromagnetics (VTEM) over the permit area
-- Structural interpretation and mapping of relevant areas
-- 3,048 metres of diamond drilling in eight holes testing geophysical and geological targets
Of the eight holes drilled, one hole (UC002) encountered altered
and brecciated volcanics over an interval of 147 metres hosting
fine-grained pyrite mineralisation. Although only weak base metal
and localised gold values were returned, the style and vertical
extent of the mineralisation is that of a significant stockwork,
and closely resembles stockwork mineralisation observed below the
massive sulphides at La Zarza. A thin faulted "slice" of similar
altered and mineralised volcanics was intersected in a second hole
(UC001) drilled some 1.5 kilometres to the east of UC002.
Following the notification by Antofagasta of its intention not
to fund further activities and withdraw from the Option, the
Company will now review its position with regards to exploration
options in light of the results of the programmes completed and the
mineralisation in hole UC002.
