Geophysical Survey at Las Morras Project (Spain) Reveals
Gold-Related Structures in Bedrock
TORONTO, ONTARIO--(Marketwired - Dec 19, 2013) - Emerita Gold
Corp. (TSX-VENTURE:EMO) (the "Company" or "Emerita") announces the
completion of geophysical exploration programs at its 100% owned
Las Morras Property in the Extremadura Region of western Spain (the
"Property") (Figure 1). The geophysical surveys consisted of Very
Low Frequency (VLF), Induced Polarization (IP) and Electrical
Resistivity Tomagraphy (ERT) surveys over the Central and Northwest
target areas. The surveys identified several anomalies that are
interpreted to represent shear zone structures coincident with the
previously identified gold geochemical anomalies (see news releases
dated August 29 and April 8, 2013). These interpreted structures
will be evaluated as potential bedrock sources for the gold
identified in the soils over the geophysical features by trenching
and, if appropriate, drilling.
Background
As previously
reported, geochemical surveys have identified two areas with strong
gold anomalies referred to as the Central and the Northwestern
areas (Figures 2 and 3). In the Central area two gold geochemical
anomalies have been identified (Figure 3), both approximately 300
meters wide and extending in an east-west direction 500 meters and
800 meters, respectively. These anomalies extend beyond the survey
limits to the east and also to the west (see press release dated
April 8, 2013).
The Northwestern
area is characterized by a single gold anomaly (Figure 3) that
extends approximately 700 meters long and over 100 meters wide in
an east-west direction. This anomaly also extends beyond the limits
of the survey area to the west and to the east (see press release
dated August 29, 2013).
Geological mapping
indicates that these gold anomalies are underlain by zones of
strong shearing in bedrock. The shear zones are developed within
the Precambrian Schist-Greywacke Complex (SGC) and are
characterized by a zone of high strain and local quartz-gold
veining, with predominantly a east-west direction. Outcrop is
limited and the geophysical surveys are designed to improve the
targeting of the follow up program.
Geophysical
Surveys
Geophysical surveys
(VLF, IP and ERT) were carried out during October and November
2013, with interpretation completed in mid December, to identify
geophysical anomalies representative of bedrock structures
potentially related to mineral occurrences. The surveying was
performed in both, the Northwestern area and the Central area.
Survey Results
The VLF survey
consisted of 27 linear kilometres in both the Northwestern and
Central areas, where measurements were performed every 10 meters.
As shown in Figure 4, in the Northwestern area 8.9 linear
kilometres were surveyed on 14 lines oriented north-south, with
lines ranging from 350 to 1,100 meters each. In the Central area
18.1 linear kilometres were surveyed on 20 lines with north-south
orientation and lines ranging from 550 to 1,100 meters each (Figure
6). The spacing between lines was determined according to the
results of the geochemical campaign (see press release dated August
29, 2013), ranging from 50 to 100 meters.
The IP and ERT
surveys consisted of 10.4 linear kilometres in both the
Northwestern and Central areas. Both the IP and ERT surveys were
measured simultaneously with the same device. The spacing between
electrodes was 10 meters, which allows detection of features up to
120 meters depth. Figure 5 shows the distribution of the 11 lines
of the IP and ERT surveys for the Central area, where 6.93 linear
kilometres were surveyed. All lines were 630 meters in length
oriented in north-south direction excepting one line with an
east-northeast orientation. In the Northwestern area 5 lines were
measured by IP and ERT, for 3.47 linear kilometres. The lines
varied in length, from 630 to 950 meters (Figure 5). The spacing
between lines was determined based on the results of the
geochemical campaign (see press release dated August 29, 2013),
ranging from 100 to 450 meters.
VLF and ERT-IP
images/profiles clearly indicate several subvertical anomalous
geophysical zones, characterized by resistivity-chargeability highs
(i.e. 300-5,000 Ωm, and >150 ms) (Figure 6).
Geophysical Survey
Interpretation
The VLF survey
showed conductive anomalies in both the Northwestern and Central
areas which have a predominantly east-west orientation. However,
some alignments of northwest- southeast direction have also been
identified. These VLF anomalies correspond to fault orientations
seen in mapping and with the geochemical data.
The IP and ERT
surveys allowed the identification of bodies and zones with high
chargeability values in the case of IP and high/low resistivity
values in the case of ERT. The survey identified bodies with a
broad east-west orientation in both the Northwestern and Central
areas, which are coincident with the VLF results.
The geophysical
data, together with geologic information and geochemical data from
the two target areas, identified features having characteristics
that would be expected from a shear zone system. This shear zone
system is interpreted to represent a possible source of the gold
found in the area and will be the focus for follow up trenching
and, if merited, drilling. The geophysical anomalies are coincident
with geochemical anomalies found in the central and northwest
areas. Furthermore, both the geochemical and geophysical anomalies
are open along their strike, particularly to the east. The extent
of the anomalous body in the Central target area, based on the
geochemical and geophysical results, is 1,200 meters long, 90
meters wide with an extension to a depth of at least 120 meters
based on the IP/IRT, corresponding to the bottom of the geophysical
profiles (Figure 6 and 7). In the Northwestern target area the
anomalous body is 600 meters long, 80 meters wide and continues to
a depth of 100 meters, corresponding to the bottom of the
geophysical profiles.
The identification
of geophysical anomalous areas (i.e., faults zones and bodies of
high resistivity and high chargeability) represent the prospective
targets for trenching and drilling (Figure 7).
Survey Methods
Both electromagnetic
(EM) and DC-geoelectrical methods were selected to perform the
survey. These methods are well-known to be suitable for
cost-effectively identifying geophysical characteristics for
geological features such as shear zones with low sulphide mineral
concentrations. The selected techniques were Very Low Frequency
(VLF) (Klein and Lajoie, 1980), Electrical Resistivity Imaging
(ERI) (Griffiths and Barker, 1993) and Induced Polarization (IP)
(Keller and Frischknecht, 1966).
The VLF measuring
was carried out with an ENVI system (Scintrex) equipped with a VLF
sensor module. The VLF sensor consists of three orthogonal coils
designed to make it an omni- directional system.
The acquiring system
for the ERT-IP was a Terrameter LS resistivimeter (ABEM SE) with 12
channels and 250 W Tx ouput. The array was implemented by 4
multicore reels of 16 take-outs each, steel electrodes and
connections, up to 64 electrode configuration system.
