VANCOUVER,
Sept. 16, 2013 /CNW/ - Mirasol
Resources Ltd. (TSX-V: MRZ, Frankfurt: M8R). Mirasol Resources
is pleased to announce assay results from the first phase of
trenching at the 100%-owned 6300 hectare Atlas gold-silver
property, located adjacent to Mirasol's Titan gold project, in the
Miocene-aged volcanic belt of northern Chile.
Mineralization at Atlas is related to a large
gold-silver bearing, high-sulphidation epithermal alteration system
that has only been partially explored by Mirasol. This type of
system hosts large, profitable mines in the Miocene-aged mineral
belt of Chile, including
Kinross's La Coipa high
sulphidation silver-gold mine (located 150 km south of Atlas and
Titan).
Two separate areas of at surface precious metal
mineralization have been identified to date within the Atlas
project (Figure 1): the Atlas Gold Zone (AGZ) and the Atlas Silver
Zone (ASZ) where AGZ is located 2 km north of ASZ. Five
trenches were completed at these prospects prior to the onset of
the southern hemisphere winter, as a partial test of previously
reported (see news release of June 10,
2013) rock chip gold and silver anomalies.
The highest gold trench results were received
from the AGZ prospect where they correlate to a series of oxide
vuggy-silica structures exposed over a 50 m interval in trench
AKI-1(Figure 2). Length weight-averaged channel results
(Table 1) at a 0.25 grams/tonne (g/t) Au eq cut-off, from this
trench include:
1.6 m of 7.28 g/t Au and 5.77 g/t Ag;
6.7 m of 2.33 g/t Au and 1.09 g/t Ag;
4.6 m of 1.18 g/t Au and 0.46 g/t Ag, and;
5.2 m of 1.46 g/t Au and 12.37 g/t Ag.
The highest trench results received for the ASZ
prospect correlate to oxide, opaline silica-alunite breccia bodies
in trench AKI-6. Length weight averaged channel results at a
0.1 g/t Au eq cut- off returned an anomalous silver interval of
55.9 m of 0.05 g/t Au and 39.9 g/t Ag. Highest channel sample
results at a 0.25 g/t Au eq cut from ASZ trenches include:
20.2 m of 0.049 g/t Au and 35.9 g/t Ag; and
26.7 m of 0.016 g/t Au and 54.76 g/t Ag,
Including 11.2 m of 0.013 g/t Au and 92.43 g/t Ag.
At ASZ, trench AKI-4 tested for the source of
high-grade Ag-bearing breccia float which has assayed up to 0.79
g/t Au and 639 g/t Ag. This trench did not locate the source
of the float; however, we now interpret that this float may come
from upslope to the northeast, potentially from extensions of the
mineralization exposed in trench AKI-6.
Preliminary geological interpretation of these
results suggests that mineralized zones at AGZ and ASZ extend under
thin cover beyond the limit of current trenching. The distribution
of gold-silver anomalous surface rock chips highlight other targets
in the AGZ and ASZ prospects that warrant trenching to test for
additional mineralization. PIMA (hand held mineral
spectrometer) analysis of the mineralized trench samples shows an
advanced argillic alteration assemblage typical of high
sulphidation epithermal precious metal systems.
A recently completed detailed ground magnetic
survey at Atlas (Figure 1) has delineated a large "magnetic quiet
zone" (diffuse magnetic low), which coincides with areas of strong
hydrothermal alteration defined by ASTER satellite imagery and
geological field mapping. The combined "foot print" of the Atlas
alteration zone covers an area in excess of 20 sq kms. The extent
of the magnetic quiet zone points to thinly covered extensions of
the alteration system that are yet to be explored.
Mirasol is planning for a southern hemisphere
summer exploration program at Atlas, aimed at testing for
extensions to the AGZ and ASZ anomalies, which will include
systematic additional geochemical sampling in the known prospects
and reconnaissance of the previously unexplored aerially extensive
Atlas alteration system.

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
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 surface samples may be
higher, lower or similar to results obtained from drill
samples.
