VANCOUVER,
March 1, 2013 /CNW/ - Mirasol
Resources Ltd. (TSXV: MRZ), (Frankfurt: M8R) is pleased to
report on the results of a high-resolution ground magnetic and a
pole-dipole electrical geophysical survey over its 100%-owned Titan
gold project in northern Chile. These surveys highlight a number
of large scale geophysical anomalies that support and extend the
prospectivity of the Titan gold target (see news release
January 21, 2013).
Mirasol has completed a 17.2 square kilometre
high-resolution ground magnetic survey and a 26.6 line-kilometre
pole-dipole (PDP) induced polarization (IP) electrical geophysical
grid at the Titan gold project. Results from these ground
geophysical surveys are consistent with the Company's geological
concept and model of an epithermal gold-bearing zone positioned
over a postulated mineralized intrusion at depth. Such systems are
known to host economic precious and base metals mineralization
elsewhere in the area.
The processed magnetics outlines two distinct,
but spatially related, magnetic features (Figure 1). The
first is a large "magnetic quiet zone" with dimensions of
approximately 3000 by 2000 metres. This feature encloses the area
of known surface hydrothermal alteration at Titan and suggests the
alteration system may extend to the west under shallow gravel
cover. The second magnetic feature is a prominent 700 by 600 metre
diameter, strongly magnetic anomaly (Figure 1). The Titan
gold-in-trench signature forms a crescent-shaped zone which
overlies the northern and western rim of the magnetic anomaly
(Figure 2).
The processed cross-sections and 3-dimensional
modelling of the PDP electrical geophysical survey (Figure 3 and
Figure 4) show an interpreted covered, highly resistive (1000 to
+2000 ohm/m) triangular- shaped tabular anomaly, up to 150 metres
thick, developed over an area of 1500 by 1400 metres. The
source of the resistive zone does not crop out in the Titan
trenches and thus the nature of the resistor is unknown. A
plausible explanation for resistive values of this magnitude may be
concentrations of silica. Based on the Company's experience,
Mirasol considers this to be a possible explanation for the
resistive blanket at Titan and that this resistive anomaly
represents a valid conceptual drill target for gold
mineralization.
Titan geophysical interpretations show a large
chargeable (10 to +20 mV/V) anomaly with dimensions of 1100 by 800
metres, which underlies the resistive blanket and encompasses the
magnetic anomaly. The chargeable anomaly is over 250 metres
thick, and extends beyond the depth of resolution of the PDP
survey. Chargeable responses of this magnitude have been
shown to be associated with sulphide mineralization. One
explanation for the combined magnetic-chargeable character and the
shape and scale of this anomaly at Titan may be a sulphide-bearing
intrusive body at depth. This chargeable anomaly represents a valid
conceptual drill target for copper-gold mineralization.
Mirasol's management is pleased to have secured
100% ownership of the high-quality Titan prospect through its
northern Chile generative
program. Mirasol's integrated team is responsible for the
geophysical results and interpretation which Mirasol believes have
substantially strengthened the understanding and prospectivity of
the Titan project. Both the resistive and chargeable-magnetic
geophysical anomalies, together with gold-in-trench surface
anomalies, represent high-priority conceptual targets that merit
drill-testing. Mirasol is in the process of constructing a
camp to support exploration activities and will apply for permits
to drill Titan in the future.

Quality Assurance/Quality Control:
Exploration of the Chile Miocene exploration program is supervised
by Stephen C. Nano, Vice President
of Exploration, who is the Qualified Person under NI 43-101.
All technical information for the Company's projects is obtained
and reported under a formal quality assurance and quality control
(QA/QC) program. All Drill Rock chip and stream sediment
samples are collected under the supervision of Company geologists
in accordance with standard industry practice. Samples are
dispatched via commercial transport to an ISO 9001:2000-accredited
laboratory in Chile for
analysis. All rock chip and drill samples are submitted to
the Laboratory with independently sourced, accredited standard and
blanks and where appropriate duplicate samples to facilitate
monitoring of laboratory performance. Certified Results are
examined by an independent qualified consultant to ensure
laboratory performance meets required standards.
Assay results from diamond drill core or RC
drill samples may be higher, lower or similar to results obtained
from surface samples.
