TINKA DISCOVERS NEW HIGH GRADE ZINC ZONE AT AYAWILCA
400 metre step-out hole hits 17.9 metres at 11.6 % Zn within a
wider zone of 62.4 metres at 5.6 % Zn
Vancouver, Canada Tinka Resources Limited (Tinka or the Company)
(TSXV:
TK) (OTC:
TRKFF) is pleased to announce partial results from drill hole
A17-56, the first hole of the 10,000 metre 2017 drill program at
Ayawilca, Peru. Drill hole A17-56 is located approximately 400
metres south of the existing Zinc Zone Inferred Mineral Resource,
and over 250 metres from any previous drill hole at Ayawilca.
Mineralization in the hole is associated with massive to
semi-massive sulphide replacements of carbonate and clastic
sediments which also host the known mineralization elsewhere. These
results report down to a depth of 238 metres only; hole A17-56 will
continue to the base of the favourable limestone unit, with further
high-grade zinc intersections expected. Tinka is mobilizing a
second drill rig to site immediately.
Key Highlights from drill hole A17-56 (results to 238 metres
depth only):
- 62.4 metres grading 5.6 % zinc from 127.5 metres depth,
including:
- 17.9 metres at 11.6% zinc from 127.5 metres depth,
including:
- 5.8 metres at 22.5 % zinc from 127.5 metres depth; and
- 5.2 metres at 12.9% zinc from 228.5 metres depth;
- All mineralized intercepts are sulphides.
The lower contact of the favourable limestone is expected at a
depth of 300-350 metres. Zinc mineralization is all sulphide
(sphalerite, marmatite) accompanied by minor galena and
chalcopyrite. True thicknesses of the zinc intersections are
estimated to be at least 90% of the downhole thickness.
Dr. Graham Carman, Tinkas President and CEO, stated: This is an
exciting new zinc discovery at Ayawilca, in a 400 metre step-out
hole from the existing mineral resource and our very first drill
hole for 2017. This early success gives the Tinka team a great deal
of confidence that our geological models and targeting methods are
working. We are drilling a magnetic anomaly at South Ayawilca, and
there are several other untested magnetic and zinc anomalies on the
property that will be drilled in 2017 (see Figures 1 & 2).
Dr. Carman continued, This discovery at South Ayawilca is very
significant. The drill hole contains some high zinc grades, and
opens up a large new area to potentially grow our zinc resources,
particularly of the higher grade chimney style mineralization we
have already identified at West Ayawilca. We look forward to
completing A17-56 to determine the extent of the mineralization to
depth. Upcoming holes will test if this mineralization links up
with existing mineral resources at West and/or Central Ayawilca.
Given this early success, we are immediately mobilizing a second
drill rig to site.

Notes on sampling and assaying:
Down-hole zinc intersections were calculated using a 2% zinc
cut-off grade over 6 metre intervals. Drill holes are diamond core
holes with recoveries generally above 70% and often close to 100%.
The drill core is marked up, logged, and photographed on site. The
cores are cut in half at the Companys core storage facility, with
half-cores stored as a future reference. Half-core is bagged on
average over 1 to 2 metre composite intervals, and sent to ALS
laboratory in Lima for assay in batches. Standards and blanks were
inserted into each batch prior to departure from Tinkas core
storage facilities. At the laboratory samples are dried, crushed to
100% passing 2mm, then 500 grams pulverized for multi-element
analysis by ICP (MS) using multi-acid digestion. Samples assaying
over 1% zinc, lead, or copper were re-assayed using precise
ore-grade AAS techniques.
The qualified person, Dr. Graham Carman, Tinkas President and
CEO, and a Fellow of the Australasian Institute of Mining and
Metallurgy, has reviewed and verified the technical contents of
this release.
About Tinka Resources Limited

flagship property being the 100%-owned Ayawilca carbonate
replacement deposit (CRD) in the zinc-lead-silver belt of central
Peru, 200 kilometres northeast of Lima. The Ayawilca Zinc Zone has
