PR Newswire (Canada)
TORONTO, Feb. 16, 2012 /CNW/ - Martina Minerals Corp. (the
"Company") is pleased to announce the receipt of new assay data by
its affiliate Comval Tribal Resources Corporation ("CTRC"),
pertaining to the TRIMA 2 project near Monkayo, Compostela Valley,
Eastern Mindanao, Philippines. Full background information was
filed by the Company on 29 August 2011 as a Technical Report by ACA
Howe International Limited ("ACA Howe") on www.sedar.com. CTRC is
exploring for epithermal gold and porphyry-style copper-gold
mineralization. A prospectivity sketch map of TRIMA 2 based on CTRC
MapInfo files is attached below. The map is an interpretive
compilation of geological, geochemical and geophysical data. A
version of this map which will locate the individual prospects
briefly mentioned below, will be available on the company website
and on SEDAR. Interested parties may also request a copy by
contacting the email addresses noted below. In December 2011, the
internationally accredited Intertek-McPhar Laboratories
Philippines, reported to CTRC multi-element assay results (Cu, Pb,
Au, Ag, Mo, As, Ba, Sr, Ti and V) of 104 rock samples collected in
September-October 2009. All of these are from channel sample
locations on TRIMA 2. Interpretation of the significance of the
results is ongoing. Threshold values were determined by calculating
the geometric mean plus one standard deviation (Cu ≥ 57 ppm, Au ≥
0.12 ppm, Ag ≥ 0.99 ppm). Anomalous values are regarded as those
results having greater than the geometric mean plus two standard
deviations (Cu ≥ 88 ppm, Au ≥ 0.23 ppm, Ag ≥ 126 ppm). -- The
copper results show 20 samples in several locations above a
threshold of 57 ppm Cu including 6 anomalous samples with 89 to 225
ppm Cu. -- The gold results show 4 samples above a threshold of
0.12 ppm Au including 1 anomalous sample with 0.98 ppm Au. The
attached map indicates the locations of those rock samples with
threshold and anomalous Cu, Au and Ag, together with locations of
those rock samples with threshold and anomalous values in other
elements. It is believed that the geochemical signatures are
depressed by tropical leaching of hydrothermally clay-altered
exposures. More sensitive analytical techniques will be utilized to
detect precious metals down to parts per billion, to define
geochemical anomalies in future surveys. Nearsurface leaching
suggests that there may be a supergene enrichment zone at depth,
such as that which occurs at the Hinoba-an deposit in Negros,
Philippines, which can only be tested by future drilling.
Previously, CTRC carried out a soil geochemical survey on TRIMA 2
on four east-west lines 400 metres apart using 50 metre sample
spacing (Line 6400N, 8000-10450E; Line 6800N, 8000-10400E; Line
7200N, 8000-10550E; Line 7600N, 8000-10250E). Soil geochemical
survey threshold values were determined by calculating the
geometric mean plus one standard deviation (Cu ≥ 104 ppm, Au ≥ 0.04
ppm). Anomalous values were regarded as those results having
greater than the geometric mean plus two standard deviations (Cu ≥
146 ppm, Au ≥ 0.06 ppm). -- The copper results show 24 samples in
several locations above a threshold of 104 ppm Cu including 9
anomalous samples with 146 to 259 ppm Cu. -- The gold results show
20 samples above a threshold of 0.04 ppm Au including 6 anomalous
samples with 0.06 to 0.122 ppm Au. In order to put the rock sample
results into perspective, ACA Howe has checked and corrected the
CTRC MapInfo data and plotted threshold and anomalous CTRC soil
copper and gold on these lines in the attached map. Including
historical geochemical copper anomalies, this indicates a copper
anomaly located in the northeast part of TRIMA 2 measuring 900
metres east-west by up to 700 metres northsouth that is open to the
north. The new rock sample data complement results described in the
Technical Report. These new data and soil geochemical data of CTRC
on lines 400 metres apart, generally confirm historic copper and
gold geochemical anomalies identified by previous operators.
Historic geochemical anomalies identified by previous operators are
currently under review and the results will be released as soon as
they are available. CTRC ground geophysical surveys (dipole-dipole
induced polarisation (IP) and ground magnetics) and detailed
mapping of the geology, silica caps and clay-alteration, confirm
the potential for the discovery of epithermal gold and possibly
deeper, porphyry-style, copper-gold mineralization, which is
summarized on the attached map. These ground geophysical surveys
indicate two large areas of high prospectivity: CENTRAL A large
central area with high chargeability at depth, coincident with an
extensive magnetic low anomaly, coincident with a large
clay-alteration zone and CTRC and historic gold geochemical
anomalies and gold anomalous CTRC rock samples. EASTERN An
extensive magnetic low anomaly coincident with another large
clay-alteration zone with CTRC copper and gold soil geochemical
anomalies and an historic arsenic geochemical anomaly in the
southern part. As mapped, the CENTRAL area is cut by a
west-northwest trending fault and the EASTERN area is cut by a
northeast trending fault. These faults may be of metallogenetic
significance and may also be the conduits of geochemical dispersion
from mineralisation at depth. Nine closely focused exploration
targets have been identified, so far, which will be further refined
when the interpretation of the combined geophysical results from
Southern Geoscience Consultants (SGC) of Perth, Western Australia,
is completed. A comprehensive fill-in and extension exploration
program is being planned to fill gaps in the available data prior
to the selection of drill targets. Commenting on the results to
date, Mr Willie McLucas, President and CEO of the Company said
"These early stage results from TRIMA 2 have lifted our confidence
that we have good indications for several epithermal gold targets,
with potential for an underlying porphyry copper target". Mr. J.G.
Langlands, BSc, FGS, FIMMM, CEng., Principal Geologist and

in settlement of a total of $230,000 of outstanding debt owing in
respect of legal, book-keeping and administrative services rendered
to the Company. The proposed debt settlement will enable the
Company to invest more of its available cash resources in mineral
exploration and development initiatives in the Philippines. This
