NEWS RELEASE November 8, 2017
TINKA MORE THAN DOUBLES INFERRED MINERAL RESOURCES AT AYAWILCA:
42.7 MILLION TONNES GRADING 7.3 % ZINC EQUIV., & 10.5 MILLION TONNES
GRADING 0.70 % TIN EQUIV.
Vancouver, Canada – Tinka Resources Limited ( “Tinka” or the “ Company”) ( TSXV & BVL: TK )
(OTCPK: TKRFF) is pleased to announce a Mineral Resource update for its 100% -owned Ayawilca zinc-
indium-silver-lead sulphide depos it in Peru which includes the addition of ~15,000 metres of drilling
completed so far in 2017. The zinc resource at Ayawilca is now estimated to be 42.7 million tonnes
grading 7.3 % zinc equivalent (ZnEq). In addition, Tinka announces an updated tin-copper-silver resource
estimated to be 10.5 million tonnes grading 0.70% tin equivalent (SnEq) . The Tin Zone and Zinc Zone
resources do not overlap. Both of the Mineral Resources were a ssigned to the Inferred category and reported
at an NSR cut-off value of US$55/tonne, as estimated by Roscoe Postle Associates Inc. (RPA Inc.) of
Toronto, Canada. Drilling beyond the Mineral Resource boundaries is continuing.
Key Highlights of Resource Updates
Inferred Zinc Mineral Resource of 42.7 million tonnes grading 6.0 % zinc, 0.2 % lead, 17 g/t
silver & 79 g/t indium (7.3 % ZnEq), including:
o 5.6 billion pounds of zinc;
o 3,361 tonnes of indium;
o 23.1 million ounces of silver; and
o 209 million pounds of lead.
Inferred Tin Mineral Resource of 10.5 million tonnes grading 0.63 % tin, 0.23 % copper, & 12 g/t
silver (0.70 % SnEq), including:
o 145 million pounds of tin;
o 53 million pounds of copper; and
o 4.2 million ounces of silver.
Dr. Graham Carman, Tinka’s President and CEO, stated: “These updated Mineral Resource estimates are a
major milestone for the Company. Ayawilca now has 5.6 billion pounds of contained zinc classified as
Inferred resources, with significant potential for more as the resources are open in several directions. The
updated Zinc mineral resource shows a 130 % increase in total contained pounds of zinc since the last
resource estimate (May 2016), and a 127 % increase in overall tonnage (from 18.8 Mt to 42.7 Mt). The zinc
grade has gone up slightly to 6.0 % Zn (from 5.9 % Zn) while the zinc equivalent grade has decreased to 7.3
% ZnEq (from 8.2 % ZnEq) due to a higher zinc price and a lower indium price. Importantly, South
Ayawilca now forms a high-grade core with 13.3 million tonnes grading 7.6 % Zn (9.5 % ZnEq) – see Table
3. In addition, the Tin Mineral Resource has increased by 60 % since the last resource estimate (May 2016)
to now include 145 million pounds of contained tin.”
“I am very pleased to report that Tinka has exceeded its two initial objectives for the year; firstly, an
additional high-grade zinc discovery was made at South Ayawilca; secondly, we doubled the contained
pounds of zinc in the resources. Furthermore, Tinka is continuing to aggressively drill outside of the
resource areas looking for new zinc discoveries and/or extensions of known mineralization - one rig is
currently drilling at Zone 3, while the second rig is testing the extensions of West Ayawilca.”

Detail of Mineral Resource Estimates
RPA updated the Ayawilca Mineral Resource estimate using the dr ill results available to October 10, 2017 (Tables 3
and 4). Two types of mineralization occur at Ayawilca, tin-co pper mineralization (“Tin Zone”) and the zinc-indium-
silver-lead mineralization (“Zinc Zone”).
The Zinc Zone Mineral Resources are hosted by Triassic Pucará G roup limestone approximately 200 metres thick and
located beneath the Goyllarisguizga Group sandstone unit which outcrops, and hosts the Colquipucro silver oxide de-
posit located 1.5 km to the north. The Zinc Zone deposit is ma de up of multiple, gently dipping lenses or ‘mantos’ in
the Central and East Ayawilca zones and as massive replacement bodies within structural zones in the West and South
Ayawilca zones, all located above Paleozoic basement rocks. Th e bulk of the polymetallic mineralization in central
Peru is located in a similar geological environment. Inferred Mineral Resources within the Zinc Zone, reported at a
US$55/t Net Smelter Return (NSR) cut-off value, are estimated t o total 42.7 million tonnes at average grades of 6.0 %
Zn, 79 g/t In, 17 g/t Ag, and 0.2 % Pb.
The increase in tonnage and zinc grade as compared to the May 2016 Mineral Resource estimate is due to an increase in
volume of the interpreted minera lized zones as a result of the addition of the high-grade South Zone discovered during
the 2017 drilling campaign, higher metal prices, and lower cut-off value.

Notes:
1. CIM definitions were followed for Mineral
Resources.
2. Mineral Resources are reported above a cut-off
NSR value of US$55 per tonne.
3. The NSR value was based on estimated metal-
lurgical recoveries, assumed metal prices and
smelter terms, which include payable factors,
treatment charges, penalties, and refining
charges. Metal price assumptions were:
US$1.15/lb Zn, US$300/kg In, US$18/oz Ag,
and US$1.10/lb Pb. Metal recovery assumptions
were: 90% Zn, 75% In, 60% Ag, and 75% Pb.
The NSR value for each block was calculated
using the following NSR factors: US$15.34 per
% Zn, US$6.15 per % Pb, US$0.18 per gram In,
and US$0.27 per gram Ag.
4. The NSR value was calculated using the follow-
ing formula:
NSR = Zn(%)*US$15.34+Pb(%)*US$6.15+
In(g/t)*US$0.18+Ag(g/t)*US$0.27]
5. The ZnEq value was calculated using the fol-
lowing formula: ZnEq = NSR/US$15.34

The Tin Zone Mineral Resources are hosted as disseminated cassi terite and chalcopyrite in massive to semi-massive
pyrrhotite lenses at the contact between the Pucará Group and u nderlying phyllite of the Devonian Excelsior Group.
Parts of the Tin Zone mineralization can occur as quartz sulphi de stockwork veinlets hosted by the phyllite. Inferred
Mineral Resources within the Tin Zone, also reported at an NSR cut-off value of US$55/t, are estimated to total 10.5
million tonnes at average grades of 0.63 % Sn, 0.23 % Cu and 12 g/t Ag. Similar to the Zinc Zones, the increase in
tonnage is due to an increased volume of the interpreted zones due to the newly discovered South Zone and a lower cut-
off grade.

Notes:
1. CIM definitions were followed for Mineral Resources.
2. Mineral Resources are reported above a cut-off grade of US$55 per tonne NSR value.
3. The NSR grade was based on estimated metallurgical recoveries, assumed metal prices and smelter terms, which include
payable factors, treatment charges, penalties, and refining charges. Metal price assumptions were: US$9.50/lb Sn, US$3/lb
Cu, and US$18/oz Ag. Metal recovery assumptions were: 86% Sn, 75% Cu, and 60% Ag. The NSR value for each block
was calculated using the following NSR factors: US$164.53 per % Sn, US$39.95 per % Cu, and US$0.27 per gram Ag.
4. The NSR value was calculated using the following formula:
US$NSR = [Sn(%)*US$164.53+Cu(%)*US$39.95+Ag(g/t)*US$0.27].
5. The SnEq value was calculated using the following formula:
SnEq = NSR/US$164.53
6. Numbers may not add due to rounding.
The Ayawilca drill database includes 44,846 m in 122 drill hole s. A set of cross-sections and level plans
were interpreted to construct three-dimensional wireframe model s at approximate NSR cut-off value of $50/t
for both Zinc and Tin Zones. Prior to compositing to two metre lengths, high Zn, Sn, In, and Ag values were
cut to 25%, 4%, 500 g/t, and 100 g/t, respectively. Block mode l grades within the wireframe models were
interpolated by inverse distance cubed. Despite lead grades be ing low it is assumed that lead and silver will
be recovered in a lead concentrate. Density was estimated to b e 3.6 t/m3 for the Zinc Zones and 3.9 t/m 3 for
the Tin Zones. All Mineral Resources were assigned to the Infe rred category due to the widely spaced drill-
ing. No Mineral Reserves have yet been estimated at Ayawilca.
The Mineral Resource estimate for the Colquipucro silver oxide deposit (Indicated Mineral Resource of 7.4
Mt at a grade of 60 g/t Ag for 14.3 Moz Ag and Inferred Mineral Resource of 8.5 Mt at a grade of 48 g/t Ag
for 13.2 Moz Ag, using US$15/t cut-off and a metal price of $24 /oz Ag) remains unchanged from the Febru-
ary 26, 2015 news release.
The Mineral Resource estimates in this news release have been c lassified in accordance with Canadian Insti-
