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
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.
