VANCOUVER,
June 28, 2017
/CNW/ - Tinka Resources Limited ("Tinka" or the
"Company") (TSXV: TK) (OTCPK: TKRFF) is
pleased to announce assay results of five recent drill holes from
its 100% owned Ayawilca zinc project in central Peru. All five holes are from South Ayawilca
and the extension of the Central Ayawilca areas, where zinc
mineralization occurs in flat-lying sulphide bodies replacing
carbonate and clastic rocks adjacent to a northeast trending
fault. Holes A17-069 and A17-070 were drilled between two
earlier drill intersections in holes A17-056 and A17-063 (see
previous releases May 3,
2017 and June 8, 2017). These
new results confirm the continuity of high grade zinc
mineralization in two separate replacement bodies (mantos) at South
Ayawilca over a strike length of at least 300 metres, with the
lower sulphide manto believed to be continuous over a one kilometre
strike from South Ayawilca to Central Ayawilca.
Key Highlights from the Five Recent
Holes
Hole A17-069:
- 29.3 metres at 10.4 % zinc, 17 g/t silver & 278
g/t indium from 271.4 metres depth, including
-
- 12.1 metres at 19.1 % zinc, 25 g/t silver & 440
g/t indium from 287.3 metres depth;
Hole A17-070:
- 1.6 metres at 15.4 % zinc, 40 g/t silver & 529 g/t
indium from 306.8 metres depth; and
- 39.3* metres at 7.1 % zinc, 13 g/t silver
& 100 g/t indium from 317.5 metres depth,
including
-
- 8.0 metres at 20.9 % zinc, 19 g/t silver & 265 g/t
indium from 340.0 metres depth;
* includes 4.3
metres of no recovery assumed zero grade
Hole A17-068:
- 0.75 metres at 6.1 % zinc, 11.6 % lead & 210 g/t
silver from 343.55 metres depth;
- 6.0 metres at 4.0 % zinc & 46 g/t silver from 382
metres depth;
Hole A17-062:
- 0.65 metres at 33.6 % zinc, 0.3 % lead & 166 g/t
silver from 152.4 metres depth (vein);
Hole was lost prior to target depth at 313
metres
Hole A17-067:
- 8.6 metres at 2.7 % zinc & 39 g/t silver from
256.4 metres depth.
See drill hole map and longitudinal section (Figure 1 and
Figure 2), and South Ayawilca cross sections in Figure
3.
Dr. Graham Carman, Tinka´s
President and CEO, stated: "We are extremely pleased with these
latest results, which confirm continuity of very high grade zinc
mineralization at South Ayawilca over at least 300 metres of
strike. Zinc mineralization also remains open in several
directions including to the south, east, and possibly to the west
where the favourable stratigraphic horizon may rapidly deepen. Hole
A17-068, drilled 350 metres along strike from A17-063, shows that
the lower mineralized manto is a continuous replacement body and
connects with Central Ayawilca. The Ayawilca sulphide system is
zoned; high grade zinc occurs outward of bodies of iron sulphide
(mostly pyrrhotite) which host tin mineralization. This
zonation has similarities to the giant Cerro de Pasco base metals deposit 40 kilometres
to the southeast. Drilling is continuing with step-out holes
at West Ayawilca, along with new targets being drilled at Zone 3
and Chaucha."
The Company has released results of the first sixteen
drill holes of an estimated planned ~30 holes for 2017.
Twenty-four holes have so far been completed, with hole A17-080 now
beginning, and many assays are pending for both zinc and tin. We
currently have one drill rig testing extensions of the West
Ayawilca resource (see Figure 1 and Figure 4). A second drill
rig is drilling at Zone 3. The third rig is setting up at the
Chaucha area, with the first hole in that area planned to test a
high priority geochemical-geophysical target. A fourth drill
rig was recently demobilized from South Ayawilca, allowing the
Company time to complete assays as well as analyze and interpret
the new data.
True thicknesses of the zinc intersections are estimated
to be at least 85% of the downhole thickness, except where
otherwise noted in Table 1. All significant results of
the 2017 program are summarized in Table 1 with the strongest
intercepts in bold text. Table 2 is a summary of all drill collar
information to date.

Notes on sampling and assaying:
Drill holes are diamond HQ or NQ size core
holes with recoveries generally above 80% and often close to
100%. The drill core is marked up, logged, and photographed
on site. The cores are cut in half at the Company's 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, an ISO 9001:2000-registered
laboratory, for assay in batches. Standards and
blanks are inserted into each batch prior to departure from Tinka's
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 are re-assayed using
precise ore-grade AAS techniques.

Forward Looking Statements: Certain
information in this news release contains forward-looking
statements and forward-looking information within the meaning of
applicable securities laws (collectively "forward-looking
statements"). All statements, other than statements of
historical fact are forward-looking statements. Forward-looking
statements are based on the beliefs and expectations of Tinka as
well as assumptions made by and information currently available to
Tinka's management. Such statements reflect the current
risks, uncertainties and assumptions related to certain factors
including, without limitations, drilling results, the
Company's expectations regarding mineral resource
calculations, capital and other costs varying significantly from
estimates, production rates varying from estimates, changes in
world metal markets, changes in equity markets, uncertainties
relating to the availability and costs of financing needed in the
future, equipment failure, unexpected geological conditions,
imprecision in resource estimates or metal recoveries, success of
future development initiatives, competition, operating performance,
environmental and safety risks, delays in obtaining or failure to
obtain necessary permits and approvals from local authorities,
community agreements and relations, and other development and
operating risks. Should any one or more of these risks or
uncertainties materialize, or should any underlying assumptions
prove incorrect, actual results may vary materially from those
described herein. Although Tinka believes that assumptions
inherent in the forward-looking statements are reasonable,
forward-looking statements are not guarantees of future performance
and accordingly undue reliance should not be put on such statements
due to the inherent uncertainty therein. Except as may be required
by applicable securities laws, Tinka disclaims any intent or
obligation to update any forward-looking
statement.
