LONDON, ENGLAND -- (Marketwire) -- 01/11/13 -- Condor (AIM:CNR), a gold exploration company focused on delineating a large commercial reserve on its 100%-owned, CIM compliant Mineral Resource of 2,375,000 oz gold at 4.6g/t at La India Project in Nicaragua, is pleased to announce the results of the initial 2790.6m of the current phase of resource infill drilling at the La India Vein Set and an update on trenching and drilling activity on the America Vein Set.
Highlights
-- 23 drillholes for 3,462m completed on La India open pit resource area to
convert the existing resource from Inferred to Indicated category.
-- Assay results from an initial 19 of these 23 drillholes for 2,790.6m of
infill drilling have confirmed gold mineralisation and outlined an
additional high-grade shoot in the North of the India-California trend.
-- Best amalgamated drill intercepts through stopes of the historic La
India Mine show: 11.95m at 5.72g/t gold, 17.15m at 4.16g/t gold and
18.00m at 4.18g/t gold.
-- Trench intercept of 10m at 5.41g/t gold has extended wide zones of gold
mineralisation on the America Vein to at least 600m strike length.
-- Further trench testing of Escondido Vein on the America Vein Set is
underway to test an additional 200m strike length.
-- 2,000m drill programme underway at historic America Mine to test for
wallrock mineralisation on the America Vein Set with one hole completed.

Mark Child, Chairman and CEO commented:
"Condor has made good progress with the completion of 3,462m drilling of a 7,000m drill programme designed with the objective of defining a total of 800,000 oz gold within the Indicated Category by targeting the conversion of the majority of the Inferred resource to Indicated within the open pit shell (currently 534,000oz is within the Indicated Category). The drill results through the historic India Mine are particularly satisfying and demonstrate that Noranda Mining left behind significant amounts of gold mineralized wallrock with drill intercepts: 11.95m at 5.72g/t gold (LIDC165), 17.25m at 4.16g/t gold (LIDC 161), 18.00m at 4.18g/t gold (LIDC170). An additional high grade ore shoot in the North of La India valley, within the open pit resource, defined by 4 drill holes on two cross-sections 50m apart bodes well for a resource increase. Figures 3 to 6 of this announcement show four cross sections of the drill results to date demonstrating the coalescence of La India and California veins with wide zones of moderate to high grade gold mineralization, which demonstrate the open pit resource in the area of the old mine workings.
The latest trench result of 10m at 5.41g/t on the historic America Mine extends the strike length to a minimum of 600m, see RNS of 30th November 2012 for further trench results. A 2,000m drill programme has commenced with a second rig on site and due to start in the next few days. The objective of the drill programme on America historic mine is to repeat the success of a 954,000 oz at 3.6g/t open pit resource on La India historic mine, which is just over 1km to the south."
Condor (AIM:CNR), a gold exploration company focused on delineating a large commercial reserve on its 100%-owned, CIM compliant Mineral Resource of 2,375,000 oz gold at 4.6g/t at La India Project in Nicaragua, is pleased to announce that 23 drillholes for 3,462m have been completed since the current phase of drilling started at the beginning of November and assay results have been received for the first 19 drillholes for 2,790.6m at La India. This is split between 22 drillholes on the La India Vein Set and 1 drillhole on the America Vein Set. Operations resumed on the 2nd January after a twelve day break over the festive season and the drilling is currently taking place on two fronts with two diamond core drilling rigs operating on the La India Vein Set and one rig on the America Vein Set, a second rig has arrived on site and is due to commence drilling on the America Vein Set in the next few days.
La India Vein Set
Twenty-two drillholes for 3,305.8m out of a 7,000m drilling programme on the La India Vein Set have been completed with the primary aim of converting zones of Inferred Category mineral resource that fall within the bounds of the current Whittle open-pit to the Indicated level of confidence. The current in-pit resource is 8.21 million tonnes at 3.6g/t for 954,000 oz gold of which 534,000 oz gold at 3.9 g/t is in the Indicated Category and 420,000 oz gold at 3.3g/t in the Inferred Category. Most of the Inferred Category is targeted for conversion. A second aim of the drilling programme is to extend the open pit to the north. A third aim of the drilling programme is to test for a parallel vein within the footwall of La India Vein. The fourth aim is to increase the resource within the existing whittle pit shell by targeting areas that have been sparsely drilled and have the potential to add in-situ ounces once drilled to the Indicated level of confidence.
Assay results have been received for 19 drillholes for 2,790.6m of drilling in the Central and North zones of the India-California vein trend. The results received are generally consistent with expectations and appear to validate the geological model used in the current resource. The infill drilling is improving definition of the transition between high-grade shoots and lower grade zones, and definition of the gold distribution within the high-grade shoots where it is currently assigned Inferred resource category (ie. Section 1200 shown on Figure 4 below).
Two areas have already been identified where the width and grade of gold mineralisation has exceeded expectations:
In the Central Zone amalgamated remnant wallrock intercepts of 11.95m (11.1m true width) at 5.72g/t gold from 103.35m drill depth (LIDC165) and 17.15m (14.6m true width) at 4.16g/t gold from 138.20m drill depth (LIDC161) show an increase in grade at width of gold mineralisation at depth and blurred the boundary at depth between what was previously considered two separate high-grade shoots (Figure 6 below).
In the Northern Zone where previously sparse drilling meant that very little wallrock gold mineralisation had been defined for inclusion in the current resource estimation a moderate to high-grade shoot has been intercepted in four drillholes on two sections located 50m apart along strike; the 1400 and 1450 sections shown on Figure 2 below. On the 1450 Section intercepts of 8.40m (7.6m true width) at 2.92g/t Au from 101.40m drill depth (LIDC168) and 2.88m (2.8m true width) at 12.16g/t gold from 104.90m drill depth (LIDC171) demonstrate continuity in gold mineralisation to more than 100m below surface (Figure 5 below)). Fifty metres along strike on the 1400 Section an intercept of 3.40m (3.2m true width) at 8.06g/t Au from 17m depth (LIDC164) represents an up-dip extension to a previous explorer's drill intercept of 5m (3.8m true width) at 4.89g/t gold from 233m drill depth (DH-LI-10A), approximately 200m below surface (Figure 4 below). This discovery is expected to have a positive influence on the next resource update.
America Vein Set
Diamond core drilling through the historic America Mine workings to test for remnant wallrock gold mineralisation has started with one drillhole for 156.6m completed to date (assay results pending). An RC drilling rig has arrived on site and will start drilling at America within the next few days. The RC rig is capable of drilling to a depth of 100 to 120m and will initially be employed to drill test shallow holes at 50m intervals along strike through the America and Escondido branches of the America Vein Set. The rig is capable of completing a drillhole every one to two days and will provide a rapid assessment of the underground potential of the Vein Set for diamond core follow-up at depth.
The America Vein Set currently contains a mineral resource of 2.11Mt at 6.0g/t for 405,000 oz gold, of which 288,000 oz gold is on the interconnected America-Constancia-Escondido veins, including 480kt at 7.8g/t for 120,000 oz gold in the Indicated category (Figure 1 below). The Indicated Resource is contained within and as extensions of the historic mine workings and is based largely on underground channel sampling. An absence of drilling, and until recently trench sampling in the wallrock of the historic mine workings means that no remnant gold mineralisation that may be present in the wallrock has been included in the current resource estimation. Recent trench sampling has demonstrated that there are significant zones of moderate to high-grade gold mineralisation remaining in the wallrock (see RNS announcement dated 30th November 2012) along the entire 500m strike length of the America Vein. Additional trenching on the America Vein has extended this strike length to at least 600m with intercepts of:
-- 10.00m at 5.41g/t gold in trench LITR152 in a trench excavated along
strike to the northwest of the previously defined zone, and
-- an infill trench intercept of 4.00m at 2.12g/t gold in trench LITR151
along strike to the southeast of the previously defined zone near the
intersection between the America-Constancia veins and the perpendicular
Escondido Vein.
The aim of the current drill and trench programme on America is to prove a second open pit resource on La India project. The drilling will better establish the grade, true thickness and orientation of the gold mineralisation and provide enough 3-Dimensional data to include the wallrock gold mineralisation of the America Mine in a future resource estimation. An initial 2,000m drill programme is planned. Additional trenching is currently underway along the 250m strike length of the Escondido Vein that was historically mined from the point where it intersects the America-Constancia veins. Positive results from the Escondido Vein could fall within the walls of a potential open pit on the America Vein and therefore add ore at the expense of waste rock. Subject to positive trench results a part of the drilling programme will be used to test the Escondido Vein at depth.

Technical Glossary
----------------------------------------------------------------------------
Assay The laboratory test conducted to determine the
proportion of a mineral within a rock or other
material. Usually reported as parts per million
which is equivalent to grams of the mineral (i.e.
gold) per tonne of rock.
----------------------------------------------------------------------------
CIM Canadian Institute of Mining, Metallurgy and
Petroleum whose terminology, definitions and
guidelines are an internationally recognised
reporting code as defined by the Combined Reserves
International Reporting Standards Committee
(CRIRSCO) as required by National Instrument 43-
101.
----------------------------------------------------------------------------
Dip A line directed down the steepest axis of a planar
structure including a planar ore body or zone of
mineralisation. The dip has a measurable direction
and inclination from horizontal.
----------------------------------------------------------------------------
Foot wall The rock adjacent to and below an ore or
mineralised body or geological fault. Note that on
steeply-dipping tabular ore or mineralised bodies
the foot wall will be inclined nearer to the
vertical than horizontal.
----------------------------------------------------------------------------
Grade The proportion of a mineral within a rock or other
material. For gold mineralisation this is usually
reported as grams of gold per tonne of rock (g/t).
----------------------------------------------------------------------------
g/t grams per tonne
----------------------------------------------------------------------------
Hanging wall The rock adjacent to and above an ore or
mineralised body or geological fault. Note that on
steeply-dipping tabular ore or mineralised bodies
the hanging wall will be inclined nearer to the
vertical than horizontal.
----------------------------------------------------------------------------
Inferred Mineral Resource That part of a Mineral Resource for which tonnage,
grade and mineral content can be estimated with a
low level of confidence. It is inferred from
geological evidence and assumed but not verified
geological and/or grade continuity. It is based on
information gathered through appropriate
techniques from locations such as outcrops,
trenches, pits, workings and drill holes that may
be limited, or of uncertain quality and
reliability.
----------------------------------------------------------------------------
Indicated resource that part of a Mineral Resource for which tonnage,
densities, shape, physical characteristics, grade
and mineral content can be estimated with a
reasonable level of confidence. It is based on
exploration, sampling and testing information
gathered through appropriate techniques from
locations such as outcrops, trenches, pits,
workings and drill holes. The locations are too
widely or inappropriately spaced to confirm
geological and/or grade continuity but are spaced
closely enough for continuity to be assumed.
----------------------------------------------------------------------------
Intercept Refers to a sample or sequence of samples taken
across the entire width or an ore body or
mineralized zone. The intercept is described by
the entire thickness and the average grade of
mineralisation.
----------------------------------------------------------------------------
oz troy ounces
----------------------------------------------------------------------------
kt Thousand tonnes
----------------------------------------------------------------------------
Mineral Resource A concentration or occurrence of material of
economic interest in or on the Earth's crust in
such a form, quality, and quantity that there are
reasonable and realistic prospects for eventual
economic extraction. The location, quantity,
grade, continuity and other geological
characteristics of a Mineral Resource are known,
estimated from specific geological knowledge, or
interpreted from a well constrained and portrayed
geological model.
----------------------------------------------------------------------------
Mt Million tonnes
----------------------------------------------------------------------------
Open pit mining A method of extracting minerals from the earth by
excavating downwards from the surface such that
the ore is extracted in the open air (as opposed
to underground mining).
----------------------------------------------------------------------------
oz Troy ounce, equivalent to 31.103477 grams
----------------------------------------------------------------------------
Strike length The longest horizontal dimension of an ore body or
zone of mineralisation.
----------------------------------------------------------------------------
True width The shortest axis of a body, usually perpendicular
to the longest plane. This often has to be
calculated for channel or drill samples where the
sampling was not exactly perpendicular to the long
axis. The true width will always be less than the
apparent width of an obliquely intersect sample.
----------------------------------------------------------------------------
Vein A sheet-like body of crystalised minerals within a
rock, generally forming in a discontinuity or
crack between two rock masses. Economic
concentrations of gold are often contained within
vein minerals.
----------------------------------------------------------------------------
Wallrock The rock adjacent to an ore or mineralised body or
geological fault.
