VANCOUVER, April 23, 2013 /CNW/ - Tinka Resources Limited (the "Company"), (TSXV: TK) (Frankfurt: TLD)
(Pinksheets: TKRFF), announces that reports from the latest geophysical surveys conducted on
the Company's wholly-owned Ayawilca project located in west-central
Peru and approximately 40 km northwest of the Cerro de Pasco mine have
been received.
The surveys and subsequent data processing were performed by Fugro
Ground Geophysics Pty Ltd ("FGG"), Lima. The most recent program
included an eastern extension to the induced polarization ("IP")
surveys performed in 2010 and 2012. The 2013 IP survey consisted of 9.3
line-km along 5 lines; the combined survey now consists of 33.7 line-km
along 17 lines, each spaced 100 m apart.
The data from the three surveys was combined and re-interpreted by FGG,
and 3-D modeling was applied. Modeling of the IP data permits
projection of interpretation to 225 m depth in the central and eastern
parts of the area where a 50 m dipole spacing was employed and to 125 m
depth in the western part of the survey area where a 25 m dipole
spacing was used.
The 3-D inversion modeling has determined two significantly large
chargeability anomalies: one in the northwest part of the study area,
the other in the central to eastern part. The northwestern anomaly
(27-40 mV/V) is much shallower than the eastern one; at 50 m depth it
spans a distance nearly 1,200 m east-west by 400 m north-south. The
stronger anomaly (25-45 mV/V) in the east-central part of the survey is
up to 800 m long east-west by 800 m north-south at 200 m depth and
remains open at depth and to the east. Between 100 m and 150 m the
east-central anomaly spans the entire length of the survey area, almost
1,700 m east-west.
Zones of high resistivity are noted to about 100 m depth along the
entire width of the survey area; these are replaced by zones of very
low resistivity at 200 m depth in the east-central and southern
portions of the area, but the results in the western portion of the
grid are not known as the survey in that area did not penetrate to that
depth. FGG has suggested that the high resistivity anomalies may be
attributed to a "silica cap" and these anomalies are believed to
represent the Gollarisquizga ("Gollyar") sandstones that overlie the
Oyon formation to a depth of 125 m to 150 m from surface.
In addition to the latest IP survey, the entire area of the three
surveys was tested with ground magnetics in 2013. Four significant
anomalies were found: NW-SE trending linear features in northwest part
of the grid, a small circular anomaly near the southern part and two
broader, elliptical anomalies near the central and eastern parts of the
grid.
The magnetic anomalies largely overlap the coincident high
chargeability/low resistivity IP anomalies. Based on the Company's
drilling data thus far, the magnetic anomalies can be accounted for by
the presence of massive and semi-massive pyrrhotite and magnetite that
commonly occurs with sphalerite, pyrite and lesser galena, arsenopyrite
and chalcopyrite. Similarly, the high chargeability and low resistivity
anomalies can be attributed to these same sulphides and strong argillic
alteration, respectively.
Based on the ground truth obtained thus far, there appears to be a
strong correlation between observed sulphide mineralization in drill
core and the three types of geophysical anomalies. This correlation
greatly enhances the potential for discovering further mineralization
along these anomalies which remain open and untested east, north and
south within the overall anomalous area that spans up to 1,700 m
east-west by up to 2,000 m north-south.
