LONDON, August 1, 2017 /PRNewswire/ --
Condor (AIM: CNR), is pleased to announce the completion of a detailed soil geochemistry survey (soil survey) over the entire
313 km² La India Project, Nicaragua. Samples were collected along 100 m, 200 m or 400 m spaced,
north-south oriented, lines and at intervals varying from 50 m to 400 m along each line over a 3 year period (see Figure 1
below). The soil survey is a key component of a multi-disciplined approach, including geological mapping and airborne geophysics,
to prove a major gold district at the Project, which currently hosts a high grade mineral resource of 18.08 M tonnes at 4.0 g/t
for 2.31 M oz gold.
Highlights
- Soil survey completed over entire 313 km² La India Project
- Soil results map major geological features, including two major feeder zones that run across the tenement in a
northwesterly direction, the La India and Andrea Corridors, an east-west linking structure, and a major eroded caldera.
- Complex structural geological setting is indicative of a major gold district
- Soil results also identify preferentially mineralized targets within these features
- 142.4 g/t gold rock chip sample identified approximately 30 m along strike from a 53.9 g/t gold rock chip on the Los
Limones prospect at the northern end of a 12.5 km mineralised corridor, 9 km north of the main La India open pit reserve.
Mark Child CEO comments:
"The completion of a soil geochemistry survey over the entire 313 km² La India Project is a major milestone in proving La
India Project hosts a major Gold District. It forms part of a multi-disciplined approach of generating new targets utilising the
knowledge from over 70,000 m drilling and 28,000 m trenching to date in the core areas, while importantly building on the
airborne geophysics survey of 2014, the detailed structure geological model of 2015, and on-going traditional geological mapping
and drilling programme.
Major gold districts tend to be discovered in complex structural settings. The soil geochemistry survey has identified two
major, mineralised basement feeder zones running NW to SE through the Project, cut by the Highway Fault, which down-throws the
southeastern part of the District, which is in turn cut by an east-west link structure, to produce such a complex structural
setting. Condor's multi-disciplined approach and a boots-on-the-ground philosophy, is generating several new drill targets and
will eventually contribute to the global gold resource."
Background
A total of 13,194 samples were analysed during 2015, 2016 and 2017. They were collected along north-south lines at 100 to 400
m spacing and at intervals of 50 to 400 m. The survey covers both 'virgin' territory, with no mapped epithermal veins, at the
broader spacing; and areas of known mineralization, such as the La India, America and Mestiza Vein Sets at the tighter spacing.
La India Project has approximately 105 km strike length of veins, of which about 55 km have been trenched or mapped in any
detail; only 13.2 km have been drill tested. The intention was to provide baseline data that can be used to generate new targets.
A detailed report, describing methods, laboratory techniques and results, is available on request. Email: information@condorgold.com .
Unlike most low sulphidation epithermal gold veins, those at La India Project tend to have very narrow, and weak, hydrothermal
alteration haloes. This is confirmed by recent SpecTerra (Short Wave Infrared) work on drill core, which showed limited
hydrothermal clay development. The veins are also very low in sulphides (e.g., pyrite and arsenopyrite) and have correspondingly
low levels of associated metals.
Interpretation
The above weak alteration and low sulphide content of the epithermal system is reflected in narrow and subtle soil geochemical
anomalies, even around high-grade gold veins, such as La India vein. Like the veins, the soils have very low contents of base
metals (e.g., copper, zinc, lead) and associated pathfinder elements (e.g., mercury, arsenic). Consequently, the best
pathfinder for gold is gold, although low level anomalism in the traditional pathfinder elements (e.g., silver, arsenic,
antimony, tellurium and thallium) does define important targets.
An analysis of the entire dataset shows two main corridors of anomalous geochemistry, referred to as La India Corridor and
Andrea Corridor (Figure 1). These extend for over twenty kilometres and coincide with major basement structures seen in the
airborne magnetics dataset. They probably represent fundamental basement structures, each acting as a feeder for ascending
hydrothermal fluids.
The known veins occur along these corridors, but are clearly shown to have better continuity than is apparent from geological
mapping. For example, the Andrea vein has much greater continuity than previously thought, extending for at least 4 km.
The corridors converge in the far northwest in an area with significant soil anomalies of gold, thallium and silver. This
coincides with a "hinge zone" seen in the airborne magnetics data. It is near Los Limones, where rock sampling has reported veins
with including two samples, 30m apart of 53.9 g/t gold and 142.4 g/t gold (Figure 3). This area is earmarked for early ground
checking, as intersection zones are generally prospective target areas.
The Highway Fault, a northeast striking post-mineral fault (Figures 1 and 2), drops down the entire epithermal system to the
southeast. This is reflected in weaker anomalies and a dominance of high level pathfinder elements. It is believed that areas
southeast of the Highway Fault contain concealed targets and that the down-thrown block preserves the top of the system at Cacao,
which includes sinter and phreatic breccias, indicating the paleosurface. There is also the possibility that the strike extension
to La India vein continues to the south, but is similarly down-thrown.
High level pathfinder elements also map a linking structure, coinciding with Cacao and Santa Barbara, both targeted for
additional drilling (Figure 1).

The data also support the interpretation of an eroded caldera to the west near the town of Santa Rosa
De Penon. This is mapped by arcuate anomalies of arsenic, antimony, mercury and bismuth. There are two main anomalies of
interest that will require follow up. The first is a broad, 3 x 5 km wide, zone of elevated arsenic, antimony, thallium,
tungsten, lead and molybdenum on the western margin of the caldera where La India Corridor intersects the caldera margin. The
second is a more focussed, 1.5 x 3 km wide, zone of elevated arsenic, thallium, molybdenum, antimony with a bismuth halo within
the caldera in an area covered by young, intra-caldera ignimbrite. Both anomalies merit further mapping.
One of the most useful tools for exploration of epithermal vein systems is commonly the gold:silver ratio. High gold relative
to silver suggests hydrothermal upflow zones, generally with better gold grades. To test this concept, soil samples below 5 ppb
gold were removed and the remaining 3,547 samples gridded. Figure 2 clearly shows elevated values at La India, the central part
of America/Guapinol, and 'Big Bend' at Mestiza (currently being drilled). There are also encouraging values at Santa Barbara and
West of Los Limones.

Condor geologists are continuing to work with the soil data and analyse it in more detail with the other available datasets,
including airborne magnetics and radiometrics, and geological mapping, to generate more targets. Follow up mapping is focussing
on the initial inventory of targets that reflect the high grade, narrow vein mineralisation that comprises the current resource
base. This includes anomalies west of Los Limones, Santa Barbara and southeast of La India.
142.4 g/t Gold and 53.9 g/t Gold Rock Chip Samples
12 km from Open Pit Reserve
Los Limones prospect, including two rock chip samples 30 m apart of 53.9 g/t gold and 142.4 g/t gold was identified during the
soil survey. The rock chips are located in a remote area in the far north of the concession package, approximately 12 km from the
nearest mineral resource at Cristalitio-Tatescame and the Highway Fault. Condor is applying for a drilling permit and plans
detailed geological mapping of Los Limones prospect in 2017 (See Figure 3 in link below)
