NEWS RELEASE October 15, 2018

TINKA CONTINUES TO EXPAND ZINC MINERALIZATION AND DISCOVERS HIGH-

GRADE SILVER VEINS AT AYAWILCA PERU

Vancouver, Canada – Tinka Resources Limited ( “Tinka” or the “ Company”) ( T S X V & B V L : T K)

(OTCPK: TKRFF) is pleased to provide an update of exploration results at the Ayawilca project in central

Peru, including results for ten recent drill holes.

Key highlights:

 Four resource step-out holes were drilled at South, Central and West Ayawilca. Hole A18-152 is a 60 metre

step-out from known mineralization at South Ayawilca. Hole A18-158 is a 100 metre step-out from known

mineralization at Central Ayawilca. A18-125 is a new intersection at Zone 3. Highlights include:

A18-152:

o 1.2 metres at 13.8% zinc, 0.8% lead, 817g/t silver and 64g/t indium from 156.3 metres depth.

A18-158:

o 1.5 metres at 9.6% zinc, 1.2% lead and 32g/t indium from 458.4 metres depth.

A18-125:

o 1.4 metres at 22.7% zinc & 99 g/t indium from 531.4 metres depth.

Note: Intercepts above are down-hole intercepts of 'mantos' hos ted by limestone or sandstone. True thicknesses

of the mantos are estimated to be at least 90% of the down-hole intercepts.

 Three holes were drilled to te st outcropping silver-lead-zinc c arbonate veins at the “Vetas” area, a target

drilled for the first time in 2018. High-grade silver intercep ts occur with visible ‘ruby silver’ minerals and

associated base metal sulphides in multiple vein structures. The grade - thickness of intercepts improve with

depth due to a more favourable host rock (sandstone). The epithermal silver-lead-zinc carbonate vein system

remains open and untested along strike and at depth. Highlights include:

Hole A18-131:

o 2.5 metres (true width) at 665 g/t silver, 1.4% zinc & 1.9% lead from 264.0 m depth, including

1.5 metres (true width) at 925 g/t silver, 1.5% zinc & 2.8% lead from 266.0 m depth.

 Tinka has drilled 20,200 metres at Ayawilca in 56 holes during the 2018 drill campaign, mostly as

resource step-out holes. New zinc discoveries at West Ayawilca and the Camp areas, in particular, have

significantly extended the mineralization beyond the existing r esources (current estimated inferred mineral

resources contain 5.6 billion pounds of zinc, 3,300 tonnes of indium, and 23 million ounces of silver with an

additional 66,000 tonnes of tin; Nov. 2017 news release ). The 2018 drill campaign has now ended, as

planned, allowing our technical team to compile all geological data and finalize interpretations.

 Roscoe Postle Associates Inc (RPA) of Toronto has been appointe d as independent consultant to un-

dertake a mineral resource update, which is expected to be finalized by November 2018.

 A Preliminary Economic Assessment (PEA) is scheduled for the first half of 2019.

Dr. Graham Carman, Tinka´s President and CEO, stated: “Tinka has been drilling continuously at Ayawilca

for 20 months since February 2017, having drilled more than 40,000 metres during that time. The Company

is now focusing on compiling and analyzing the large quantity of drill hole information, completing a mineral

resource update, expanding metallurgical test work, and advancing the project to a PEA in 2019. Tinka is well

positioned financially with C$13 million in cash reserves at the end of September 2018 and no debt.”

“The Ayawilca zinc mineral resource is expected to in crease meaningfully as a result of this year's drill pro-

gram. Ayawilca is already one of only a handful of independently owned, large zinc resources, located in a

mining-friendly jurisdiction with good infrastructure. The property has already attracted interest from a num-

ber of large mining companies, and the Company has signe d multiple confidentiality agreements and con-

ducted several site visits. We are encouraged by the level of potential strategic interest and look forward to

completing the resource update and a PEA. (Note that there can be no assurance the Company will pursue a

transaction or that a transaction, if pursued, will be completed.)”

“The discovery of epithermal silver-bearing veins at the “Vetas” area is a further encouraging development.

Although we do not yet have sufficient holes to add to our resource base, the vein system offers additional

exploration upside given the high silver grades, while grades and vein thicknesses appear to increase at depth

when hosted in the lower sandstone (a quartz-rich unit) . We believe further exploration of the veins is war-

ranted. Further drill testing of the veins, along with other targets, is planned for 2019.”

Summary of Ayawilca Inferred Zinc Zone Mineral Resources (November, 2017)

South Ayawilca: 13.3 million tonnes at 9.5 % ZnEq (7.6 % zin c, 0.2 % lead, 25 g/t silver & 118 g/t indium);

West Ayawilca: 9.0 million tonnes at 7.2 % ZnEq (6.1 % zin c, 0.2 % lead, 14 g/t silver & 64 g/t indium);

Central Ayawilca: 13.0 million tonnes at 5.7 % ZnEq (4.7 % zin c, 0.3 % lead, 13 g/t silver & 54 g/t indium);

East Ayawilca: 7.5 million tonnes at 6.2 % ZnEq (5.1 % zinc , 0.2 % lead, 13 g/t silver & 69 g/t indium);

TOTAL: 42.7 million tonnes at 7.3 % ZnEq (6.0 % zinc, 0.2 % l ead, 17 g/t silver & 79 g/t indium).

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.

Drill core is orientated and marked as core is removed from the core barrel. In this way geological features in the core

such as stratigraphic layering, fault structures, fractures and veins can typically be measured and interpreted in 3D space.
