TINKA DRILLS 10.4 METRES GRADING 44.0% ZINC IN NEW DISCOVERY OF
EXCEPTIONAL ZINC GRADE AT AYAWILCA
Vancouver, Canada – Tinka Resources Limited ( “Tinka” or the “ Company”) ( T S X V & B V L : T K)
(OTCPK: TKRFF) is pleased to announce assay results for seven recent holes from its ongoing resource step-
out drill program at the Company’s 100%-owned Ayawilca project, central Peru. Six holes are reported from
the West Ayawilca area (holes A18-117, 120 to 122, 126, 129) and one from the Central area (A18-127).
Hole A18-129 has intersected exceptional grades of zinc sulphid e mineralization at West Ayawilca in a new
setting for mineralization at Ayawilca. A mineralized interval of 10.4 metres grading 44.0% zinc occurs
within a zone consisting of more than 90% zinc sulphides (sphal erite). This is the highest-grade zinc
intersection ever encountered at Ayawilca over a significant in terval. The high-grade mineralization
occurs immediately beneath phyllite (metamorphic rock) within a repetition of the Pucara limestone
formation which is favourable for mineralization and typically found above the phyllite. The
mineralized interval is interpreted to be flat-dipping and close to true thickness. This is the first time that
Tinka has tested the proposition that there may be a repetition of the mineralized Pucara limestone under the
phyllite encountered at the base of most other holes at Ayawilc a. It is notable that such an outstanding zinc
intercept has been drilled in the first repetition of the Pucar a limestone encountered thus far. Additional drill
holes are planned to test for the continuation of the high grade mineralization in this repeated limestone.
The new discovery opens up significant areas of untested potent ial, both beneath and adjacent to the
existing mineral resource. Most of the previous drill holes at Ayawilca were stopped a few metres into the
phyllite, which had been considered to be ‘basement’. A new int erpretation of the geology at West Ayawilca
indicated that the favourable limestone unit could be repeated under low angle ‘thrust’ faults, a concept that is
now corroborated.
Three drill rigs continue to operate at the project 24/7 in the resource expansion program. Two rigs are drilling
d e e p h o l e s a t W e s t A y a w i l c a , w h i l e t h e t h i r d r i g i s a t S o u t h A yawilca testing for repetitions of the
mineralization beneath the South Ayawilca resource.

Dr. Graham Carman, Tinka´s President and CEO, stated: “The exceptional zinc grade in hole A18-129 is very
exciting as it confirms Ayawilca mineralization can be very high-grade, while a repetition of the favourable
Pucara limestone opens up a new exploration target at depth and also down-plunge of the new intercept.
Previously, it was thought that the phyllite metamorphic ro ck represents a ‘floor’ to the zinc mineralization.
Past drill holes were typically stopped a few metres into the phyllite, and some holes at Ayawilca may have
been stopped prematurely.”
“The objectives of the drill program are to find additio nal high-grade zinc resources, as well as to improve
the geological understanding of the Ayawilca deposit, which is evolving as more holes are drilled. The three-
rig drill program is now focused on testing extensions of the zinc resources at West and South Ayawilca,
including deeper repetitions of the limestone-hosted replacement mineralization, as well as possible
connections of these areas with Central Ayawilca – see Figure 2.”
“The three rigs on site are expected to be operating until at least mid-August 2018, at which time the number
of rigs will be reviewed subject to results. Drilling at the Zone 3 area, which has been one of our main target
areas, will resume later in the year. A Preliminary Econ omic Assessment is planned for the fourth quarter of
2018.”
West Ayawilca Geology – a revised interpretation
The main geological rock units observed at Ayawilca are an uppe r sandstone (Goyllar Group), a limestone
(Pucara Formation) which hosts most of the zinc mineralization as sulphide replacement of the limestone, and
a lower phyllite metamorphic rock (Excelsior Group). The obser vation by Tinka geologists of mineralized
limestone underneath the phyllite in hole A18-129 is groundbrea king, as it opens up potential for additional
zinc resources beneath and adjacent to the existing resources. Of particular importance is that the repeated
section of Pucara limestone in A18-129 hosts much higher-grade mineralization than average, and the
predominant zinc species is the relatively low iron “ruby” sphalerite.
Hole A18-129 intersected 70 metres of Pucara limestone, 10 metres of phyllite, and then another 70 metres of
limestone before cutting phyllite once again. Tinka geologists believe that the repetition in the limestone is as
a result of a low-angle reverse fault which lies at the base of the upper phyllite, forming a ‘thrust’ slice in the
geology at West Ayawilca (see Figure 4). Other thrust slices m ay also occur deeper in the sequence. The
faulting is believed to have occurred prior to the zinc mineralization, but the low-angle faults acted as conduits
for the mineralization. Zinc mineralization is hosted predomina ntly in the hanging wall position of the faults.
The thrust faulting post-dated the folding of the limestone-sandstone sequence which formed the anticline fold
at West Ayawilca.

Notes:
1 US$55/t NSR cut off was used. Metal price assumptions were US$1 .15/lb Zn, US$300/kg In, US$18/oz Ag, US$1.10/lb Pb. Metal rec overy
assumptions were 90% Zn, 75% In, 60% Ag, and 75% Pb for the ZnEq calculation.
2 The NSR value was calculated using the formula: NSR = Zn(%)*US$15.34+Pb(%)*US$6.15+In(g/t)*US$0.18+Ag(g/t)*US$0.27
3 The ZnEq value was calculated using the formula: ZnEq = NSR/US$15.34

Notes on sampling and assaying
Drill holes are diamond HQ or NQ size core holes with recoverie s 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 bag ged on average over 1 to 2 metre composite intervals and
sent to SGS laboratories in Lima 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 using multi-acid digestion. Samples assaying over 1% zinc, lead, or copper
and over 100 g/t silver are re-assayed using precise ore-grade AAS techniques. Samples assaying over 200 ppm tin are
re-assayed by fusion methods with an AAS finish (method AAS90B).
