Updated Mineral Resource for La India Project, Nicaragua.
Highlights
-- CIM compliant, Mineral Resource of 2,375,000 oz gold at 4.6 g/t, increase by 46% and exceeds year end target of 2,000,000 oz gold
-- Reporting of initial open pit Mineral Resource of 954,000 oz gold at 3.6g/t gold -- Underground Mineral Resource of 1,418,000 oz gold at 5.5g/t gold -- Indicated Mineral Resource 751,000 oz gold increases 285% -- Maiden silver Mineral Resource of 2,280,000 oz silver at 6.5g/t silver. -- 2,410,000 oz gold equivalent (adding the gold and silver Mineral Resources)
Mark Child, Chairman and CEO commented:
"The Resource update of 2,375,000 oz gold at 4.6 g/t gold for La India Project is split for the first time into a high grade open pit resource, of 954,000 oz gold at 3.6 g/t gold using a 1.0 g/t cut off in addition to an underground resource of 1,421,000 oz gold at 5.5 g/t gold. The Indicated Mineral Resource has increased 285% to 751,000 oz gold. I am particularly pleased that the open pit resource contains 534,000 oz gold at 3.9 g/t in the Indicated category as this provides the Company with a higher degree of certainty that La India Project can be fast tracked towards production and due to the high gold grade should be attractive from an economic perspective. The independent resource has been reported to CIM standards for the first time as opposed to JORC Code in order to broaden the appeal of the Company to North American investors. The Company intend to compile a NI43-101 style technical report to detail the current update in due course.
The La India Project has considerable potential to continue the expansion of the size of the gold Mineral Resource. It continues to develop into 3 main areas, separated by 1km to 1.5km, that could feed a centralised processing facility: The 3 main areas consist of the La India Vein Set of 1,484,000 oz gold at 4.0 g/t (containing the open pit resource), the America Vein Set of 403,000 oz gold at 6.0 g/t gold and the Mestiza Vein Set of 334,000 oz gold at 7.0g/t gold. The next phase of drilling will aim to increase the size and geological confidence of the open pit resource and determine whether the historic mine on the America vein, which produced approximately 200,000 oz gold at 13.0 g/t prior to its closure in 1956 is similar to La India vein and also has coalescing veins and contains a resource with potential for open pit mining".
Condor (AIM:CNR), a gold exploration company focused on delineating a large commercial resource on its 100%-owned La India Project in Nicaragua is pleased to announce an upgraded Mineral Resource on the La India Project. The Mineral Resource on the La India Project now stands at 16.2 Mt at 4.6 g/t for 2,375,000 oz gold, including 5.3 Mt at 4.4 g/t for 751,000 oz gold in the Indicated Mineral Resource category with the balance in the Inferred category. In addition, there is 2,280,000 oz silver at a grade of 6.5 g/t silver, calculated on the La India and California Veins only where there is sufficient silver assay data. Combining the gold and silver using a 67:1 silver to gold ratio, the Mineral Resource for La India Project is 2,410,000 oz gold equivalent
The most significant development is a maiden open pit Mineral Resource reported within a US$1,400 per ounce gold optimised Whittle pit shell above a cut-off grade of 1.0g/t gold. As a result, the in-pit Mineral Resource is 8.21 million tonnes at a grade of 3.61g/t gold containing 954,000 oz gold of which 534,000 oz gold at 3.9 g/t is an Indicated Mineral Resource and 420,000 oz gold at 3.3 g/t is an inferred mineral resource. Beneath the optimised Whittle open pit shell there is an underground resource of 2.77 million tonnes containing 432,000 oz gold split between La India Vein with 104,000 oz gold at 7.8 g/t gold and the California veins with 328,000 oz gold at 4.4 g/t gold. Furthermore, there are 1,561,000 oz silver at 5.5 g/t silver within the open pit and 719,000 oz silver at 8.1 g/t silver beneath the open pit.
Another significant development is the increase in Indicated Mineral Resources to 751,000 oz at 4.4 g/t gold, from 264,000 oz gold at 7.1 g/t gold. The current indicated resource is split between an open pittable resource of 4.22 million tonnes at a grade of 3.9 g/t gold containing 534,000 oz gold and an underground mineral resource of 1.05 million tonnes at 6.4 g/t gold containing 217,000 oz gold.
SRK has produced the maiden silver Mineral Resource for the La India and California veins of 10.9 Mt at 6.5 g/t silver for 2,280,000 oz. The addition of the silver in the form of a gold equivalent increases the Mineral Resource for the La India and California veins from 1,386,000 oz to 1,420,000 oz gold equivalent, with a resultant increase in the grade from 3.9 g/t gold to 4.0 g/t gold equivalent. Gold equivalent have been calculated based on the formula gold equivalent = (gold g/t + 0.0148 * silver g/t).
The resource update is based on some 40,298 m of drilling, 7,200 m of trench sampling and over 9,000 original underground mine grade control channel samples on nine of the veins within the La India Project area. The company completed fifty-nine drill holes for 7,096 m and 2,500 m of trenching between mid-April and the end of July 2012, on the India-California vein trend with the aim of increasing the confidence in the estimates to an Indicated category by targeting areas considered to have open pit and underground mining potential. All samples taken during the 2011 and 2012 programme have been assayed for gold and silver.
The bulk of the increased in the Mineral Resource is focused on the La India Vein Set, which has increased from 730,000 oz gold at 5.3 g/t to 1,484,000 oz gold at 4.0 g/t and now represents 62% of the Project's total Mineral Resource.
The increase in tonnage and drop in grade can be attributed to the re-modelling of the La India and California veins (wider lower grade, coalescing). The December 2011 SRK Mineral Resource Report documented a merging of parallel vein structures into a central brecciated zone, based on a few significant drill hole intersections. Subsequent drilling during 2012 has confirmed and further emphasised the presence of coalescing veins highlighted in the last Mineral Resource Estimate for the project, most notably within the 'central zone' (La India and California veins) of the mineralised structure, which has significantly increase the modelled vein thickness. The 2012 model has focused on the four targets along the Southern and Central segments of the India-California structure where gold mineralisation is concentrated into wide moderate to high-grade shoots using 50m drill and trench spacing; the 'South' target where a high-grade zone is recognised at and beyond the southern limit of the historic mine workings, and the 650m long 'Central Zone' target which, although historically mined to a depth of up to 200m below surface has been shown to retain significant gold mineralisation in the wallrock of the historic mine workings.
The modelled veins are geologically continuous along strike for up to 2.5 km, showing a down-dip extent that ranges from 150 m to greater than 350 m, and a thickness that commonly varies between 0.5 to 2.5 m, reaching over 20 m in areas of significant swelling. Locally, the mineralised veins display anastamosing and bifurcating features, pinch and swell structures, fault brecciation and fault gouge.
The La India and California veins modelled during the September 2012 update have dimensions broadly comparable with other veins on the La India Concession. SRK estimates the historic La India mine workings to have an average thickness of approximately 2.0 m, while by comparison the aggregate remnant wallrock mineralisation and the California veins can average between 2.5 and 10.0 m in different portions of the deposit, and reaching up to 25 m wide in areas where multiple veins coalesce.
On the nearby America Vein Set the addition of 4 drill holes on the Guapinol vein has acted to increase the overall tonnage (as a function of widening the modelled vein at depth), however a single low-grade intercept has resulted in an associated drop in grade, with the resultant contained metal showing limited variation.
The latest Resource has established the La India Vein Set as the principal resource area with wide zones of moderate to high-grade gold mineralisation on the India-California veins now recognised as having the potential for a large open-pit mine development and the potential for the discovery of additional resources with both open-pit and underground mining potential on the depth and strike extension of this vein trend.
Table 1 below gives SRK's CIM compliant Mineral Resource Statement as at 14 September 2012 for the La India Project, as signed off by Ben Parsons, a Competent Person as defined by the CIM Code.

((1) Open Pit Mineral Resource is reported at a cut-off grade of 1.0 g/t gold. Cut-off grades are based on a price of US$1400 per ounce of gold and gold recoveries of 90 percent for resources, without considering revenues from other metals. Note optimised pit shells are based on Indicated and Inferred Mineral Resources
(2) Underground Mineral Resources beneath the open pit are reported at a cut-off grade of 2.3 g/t gold. Cut-off grades are based on a price of US$1400 per ounce of gold and gold recoveries of 90 percent for resources, without considering revenues from other metals.
(3) Mineral Resources as previously quoted by SRK (22 December 2011) are reported at a cut-off grade of 1.5 g/t.
(4) Mineral Resources are not Ore Reserves and do not have demonstrated economic viability. All figures are rounded to reflect the relative accuracy of the estimate and have been used to derive sub-totals, totals and weighted averages. Such calculations inherently involve a degree of rounding and consequently introduce a margin of error. Where these occur, SRK does not consider them to be material. All composites have been capped where appropriate. The Concession is wholly owned by and exploration is operated by Condor Gold plc
There is also considerable potential for the discovery and definition of further Mineral Resource in La India Project on the neighbouring America and Mestiza vein sets and elsewhere within the La India Project. Three styles of mineralisation are targeted: (1) wider zones of lower grade mineralisation hosted by multiple close spaced veins and/or quartz breccias that may be amenable to bulk open pit mining, focusing on the America and Mestiza Vein sets and also the Central Breccia Prospect. (2) Further extension to depth and along strike of the principal veins, (3) definition of new narrow vein resource where previous trench sampling has already defined the veins at surface.

Resource Estimate Notes
The Mineral Resource Estimate completed by SRK Consulting (UK) Ltd ("SRK"), and the reporting standard adopted for the reporting of the Mineral Resources is that defined by the terms and definitions adopted the terminology, definitions and guidelines given in the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) Standards on Mineral Resources and Mineral Reserves (December 2005) as required by National Instrument 43-101.
The majority of the drilling during 2012 has been focused on the La India and California veins for which SRK created a block model was generated using block dimensions of 25 metres x 25 metres x 10 metres, into which up to 24 x 2 metre composite samples per block were used for estimation employing an ordinary kriging routine. All composites have been capped where appropriate.
SRK has considered geological continuity, grade continuity, quality of the digitised database, sampling density, distance of block estimates from samples and estimation quality in order to classify the deposit in accordance with The CIM Code. Data quality, drill hole spacing and the interpreted continuity of grades controlled by the veins has allowed SRK to classify portions of the veins in the Indicated and Inferred Mineral Resource categories. The resource statement has been depleted for historical mining.
The La India and California Mineral Resource is constrained within an optimised Whittle open pit shell, with SRK electing to use a 30% premium applied to market consensus long term gold price forecasts from over 30 contributors, resulting in a long term optimistic gold price of US$1400 /oz; this approach is in line with other gold producing companies' reporting methods. For the other optimised Whittle input parameters, SRK has briefly reviewed typical mining, processing, and administrative costs for a range of gold mines in the region. Based on the assumed costs and a recovery of 90% using conventional gold mineralised material processing. SRK has applied a cut off grade of 1.0 g/t gold for the material with potential to be mined from surface, based on benchmarked parameters defined as part of an initial conceptual study and a cut-off grade to 2.3 g/t gold material with the potential to be mined underground.
In the case of veins not updated as part of the 2012 update SRK has quoted the Mineral Resource as reported in the previous Mineral Resource Statement (dated 30 December 2011), using a cut-off grade of 1.5 g/t gold.

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 Code The reporting standard
adopted for the reporting
of the Mineral Resources
is that defined by the
terms and definitions
given in the terminology,
definitions and guidelines
given in the Canadian
Institute of Mining, Metallurgy

Diamond core drilling A drilling method in which
penetration is achieved
through abrasive cutting
by rotation of a diamond
encrusted drill bit. This
drilling method enables
collection of tubes of
intact rock (core) and
when successful gives
the best possible quality
samples for description,
sampling and analysis
of an ore body or mineralised
structure.
---------------------- --------------------------------------
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.
---------------------- --------------------------------------
Down-dip Further down towards the
deepest parts of an ore
body or zone of mineralisation
---------------------- --------------------------------------
Fault The plane along which
two rock masses have moved
or slide against each
other in opposing directions
---------------------- --------------------------------------
Fault breccia A rock made up of angular
rock fragments cemented
together by a finer grained
matrix formed by the mechanical
grinding of rock along
the fault plane during
movement of the fault
---------------------- --------------------------------------
Fault gouge Clay filling a fault that
was formed by the mechanical
grinding of rock along
the fault plane during
movement of the fault
---------------------- --------------------------------------
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.
---------------------- --------------------------------------
Gold Equivalent Gold equivalent grade
is calculated by dividing
the silver assay result
by 60, adding it to the
gold value and assuming
100% metallurgical recovery
---------------------- --------------------------------------
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 That part of a Mineral
Resource 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

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

network of quartz rock.
The quartz is deposited
from saturated geothermal
liquids filling the space
between the rock fragments.
---------------------- --------------------------------------
Quartz veins Deposit of quartz rock
that develop in fractures
and fissures in the surrounding
rock. They are deposited
by saturated geothermal
liquids rising to the
surface through the cracks
in the rock and then cooling,
taking on the shape of

Trench The excavation of a horizontally
elongate pit (trench),
typically up to 2m deep
and up to 1.5m wide in
order to access fresh
or weathered bedrock and
take channel samples across
a mineralised structure.
The trench is normally
orientated such that samples
taken along the longest
wall are perpendicular
to the mineralised structure.
---------------------- --------------------------------------
True width The shortest axis of a
3 dimensional object (i.e.
ore/mineralised body),
usually perpendicular
to the longest plane.
This often has to be calculated
where channel or drill
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.
---------------------- --------------------------------------
Wallrock The rock adjacent to an
ore or mineralised body
or geological fault.
