This successful drill program has resulted in the decision by the Company to update the Preliminary Economic Assessment (PEA) for the Ayawilca project including an update of the mineral resource estimations; the PEA is expected to be completed by March 2024.
Improved metallurgy of the Tin Zone supported by test work, with ongoing work improving the silver recovery of the Silver Zone.
Project moving forward towards decision to undertake a pre-feasibility study.
The Company is fully funded to carry out its current work plans.
Dr. Graham Carman, Tinka’s President and CEO, stated: “To continue the advancement of our flagship Ayawilca project, we believe it is a necessary next step to update the PEA and technical report on the project following the successful recent drilling campaign. An updated PEA will include a processing scenario for both the Ayawilca Zinc Zone and the Tin Zone and incorporate an update to the mineral resources.”
“We are very encouraged by the improvement in the tin recovery and concentrate grades following metallurgical test work on the Tin Zone mineralization. In addition, metallurgical test work of the Silver Zone mineralization is in progress. These final test work results, when available, will provide support for key assumptions on silver recoveries in the PEA.”

TINKA DISCOVERS HIGH GRADE TIN MINERALIZATION AT SOUTH AYAWILCA
April 14, 2021
Vancouver, Canada – Tinka Resources Limited (“Tinka†or the “Companyâ€) (TSXV & BVL: TK) (OTCQB: TKRFF) is pleased to announce tin assays from the 7,600 metre, 21-hole, 2020-2021 drill program recently completed at the Ayawilca project in central Peru.
While the focus of the 2020-2021 drill program was on resource definition of zinc-silver mineralization, significant tin mineralization was also intercepted in several of the drill holes. Of note, Tinka has discovered a new zone of high-grade tin mineralization at South Ayawilca, immediately adjacent to the highest grade zinc resource. This is the first time that tin mineralization of such high grade has been discovered at South Ayawilca. Tin mineralization was intersected in eight adjacent drill holes, including seven of the recent holes, in zones that typically contain very minor or no zinc mineralization. The tin mineralization is believed to be hosted by multiple, flat-dipping lenses with each lens up to 12 metres in thickness and with horizontal dimensions of approximately 200 metres, remaining open to the north. Tin mineralization in hole A21-187 (12 metres grading 3.1% tin) occurs 40 metres above zinc mineralization in the same hole (4.1 metres grading 17.7% zinc) (link to news release). Tin occurs as cassiterite (SnO2), the most common ore-forming mineral of tin. Refer to maps in Figures 1 and 2 for the location of the tin mineralization.
Tin is traditionally used as a solder and for tin plating of other metals but it also is a key metal in new applications such as autonomous and electric vehicles, renewable energy, energy storage, and advanced computing. Tin has the highest value of the major base metals and is currently trading at around US$27,000 per tonne or 3 times the value of copper and 9 times the value of zinc (source).

TINKA DRILLS 8 METRES GRADING 31% ZINC & 225 GRAMS PER TONNE SILVER AT AYAWILCA
January 28, 2021
Vancouver, Canada – Tinka Resources Limited (“Tinka†or the “Companyâ€) (TSXV & BVL: TK) (OTCPK: TKRFF) is pleased to announce assay results for seven drill holes from the ongoing resource expansion and infill drill program at the Ayawilca project in Peru. Hole A20-177 intersected very high grade vein-style zinc-silver-lead mineralization outside of the zinc resource at about 100 metres depth. Three holes (A20-178, 177 & 175) also successfully intersected high grade manto-style zinc mineralization at the Camp area. Hole A20-179 was an infill hole at the West area which intersected two wide zones of mineralization with better than expected zinc grades. The other three holes intersected extensions of zinc-rich mineralization at the South area (holes A20-176, 174, 172). Tinka has now completed 6,500 metres of the planned 7,500 metres in the resource drilling program. Sixteen holes have been completed with two in progress (A21-185 & 186) and at least two more are planned before the end of the program. Results are now reported for half of the drill holes in the current program.
Drill Highlights:
Camp area:
Hole A20-177
*19.2 metres @ 15.6% zinc. 1.5% lead & 154 g/t silver from 101.1 metres depth, including
*1.9 metres @ 24.9% zinc, 7.7% lead & 604 g/t silver from 101.1 metres depth; and
*7.8 metres @ 31.3% zinc, 1.7% lead & 225 g/t silver from 112.5 metres depth; and
34.0 metres @ 7.4% zinc & 8 g/t silver from 290.0 metres depth, including
16.6 metres @ 9.5% zinc & 10 g/t silver from 298.3 metres depth;
Hole A20-178
42.1 metres @ 6.3% zinc & 14 g/t silver from 281.9 metres depth, including
20.4 metres @ 9.8% zinc & 15 g/t silver from 289.5 metres depth, including
7.9 metres @ 16.7% zinc & 27 g/t silver from 302.0 metres depth.
Hole A20-175
*1.2 metres @ 43.6% zinc & 212 g/t silver from 136.5 metres depth; and
16.4 metres @ 4.4% zinc & 7 g/t silver from 235.7 metres depth.
West Area:
Hole A20-179
31.9 metres @ 6.0% zinc & 15 g/t silver from 224.1 metres depth, including
11.8 metres @ 8.4% zinc & 32 g/t silver from 242.0 metres depth; and
34.6 metres @ 7.0% zinc & 6 g/t silver from 270.0 metres depth, including
12.2 metres @ 9.4% zinc & 5 g/t silver from 276.0 metres depth.
South Area:
Hole A20-176
11.2 metres @ 5.3% zinc & 27 g/t silver from 336.2 metres depth.
Hole A20-174
1.2 metres @ 10.3% zinc & 4 g/t silver from 318.6 metres depth.
Hole A20-172
*0.9 metres @ 5.9% zinc, 5.3% lead & 733 g/t silver from 178.7 metres depth; and
7.2 metres @ 5.1% zinc & 15 g/t silver from 277.2 metres depth.
Mineralization is mostly associated with gently-dipping sulphide “mantos†hosted in limestones. True thicknesses of the mantos are estimated to be at least 90% of the downhole thicknesses. The intervals marked * are vein-style hosted by sandstones and have an unknown true thickness. Refer to map and cross sections in Figures 1 and 2.
President and CEO of Tinka, Dr. Graham Carman, stated: “The 2020-21 Ayawilca drill program continues to deliver high-grade zinc mineralization with significant silver credits. We are particularly excited about the very high-grade zinc-silver vein intersection in hole A20-177, one of the best grade intersections we have ever had at Ayawilca and especially attractive as it occurs at shallow depth. The vein-style mineralization was intersected at a low-angle to the drill core axis so the true width of the vein is currently unknown. The thick vein is hosted in the quartz sandstone member of the Goyllar Formation which was not previously considered as a favourable host rock. The shallow nature of the mineralization (about 100 m depth) opens up the possibility for high-grade zinc-silver-lead resources much closer to surface than previously thought. We plan to follow up this vein with more drilling before the end of the current program to better define its geometry and extent.â€
“Drill holes at the Camp area have also discovered strong manto-style zinc mineralization outside of the current resource hosted within the limestones. Drilling is continuing currently at the South area with two rigs operating. We expect the program to be completed in February, after which time the data will be compiled for a resource and PEA update. We continue to believe that Ayawilca is perfectly positioned to take advantage of the current positive market sentiment towards base metals, and we look forward with anticipation to the results for the final half of the drill program.â€

TINKA DRILLS 39 METRES GRADING 9.3% ZINC AT AYAWILCA
Vancouver, Canada – Tinka Resources Limited (“Tinka†or the “Companyâ€) (TSXV & BVL: TK) (OTCPK: TKRFF) is pleased to announce results of four drill holes from the current drill program at Ayawilca. Three of the holes targeted extensions of indicated resources at West and South Ayawilca (holes A20-170, 171 & 175) while one hole is an infill hole at West Ayawilca (A20-173).
The Company has now completed approximately 6,000 metres of the planned 7,500 metres drill program in the resource expansion program. Many of the completed holes have targeted zinc-silver mineralization in the area between West and South Ayawilca, an area that has not been well drill tested (see Figure 1). Two rigs are operational and are expected to remain at site until February 2021. So far, sixteen diamond drill holes have been completed (A20-169 to A21-184). Results for eleven of these holes are pending.
Drill Highlights:
Hole A20-170 (South Ayawilca)
38.8 metres @ 9.3% zinc & 14 g/t silver from 282.6 metres to 321.4 metres depth, including
13.7 metres @ 15.9% zinc & 26 g/t silver from 282.6 metres depth;
The wider intersection is an extension of the mineralized interval reported on November 30, 2020, to a depth of 309 metres only; and
4.5 metres @ 14.5% zinc & 31 g/t silver from 340.1 metres depth; and
5.0 metres @ 5.2% zinc. 0.6% lead & 16 g/t silver from 352.4 metres depth.
Hole A20-173 (West Ayawilca)
18.7 metres @ 7.2% zinc & 11 g/t silver from 187.3 metres depth, including
7.3 metres @ 11.8% zinc & 21 g/t silver from 196.0 metres depth; and
23.9 metres @ 6.2% zinc & 8 g/t silver from 252.1 metres depth; and
2.8 metres @ 15.0% zinc & 6 g/t silver from 284.0 metres depth.
Hole A20-175 (West Ayawilca)
1.2 metres @ 43.6% zinc, 0.5% lead & 212 g/t silver from 136.5 metres depth, and
14.3 metres @ 5.0% zinc & 9 g/t silver from 235.7 metres depth.
Hole A20-171 (West Ayawilca - vein style)
0.4 metres @ 19.6% zinc & 99 g/t silver from 110.0 metres depth.
Mineralization in holes A20-170, A20-173 & A20-175 is associated with gently-dipping sulphide rich “mantos†hosted in limestones. True thicknesses of the mantos are estimated to be at least 90% of the downhole thicknesses. Mineralization in hole A20-171 is vein style hosted by sandstones which has an unknown true thickness. Cross sections of holes A20-170 and A20-173 are shown in Figures 2 and 3, respectively.
President and CEO of Tinka, Dr. Graham Carman, stated: “Ayawilca continues to produce strong zinc results with significant silver credits. Hole A20-170 is expected to expand our indicated resources at South Ayawilca, with mineralization still open to the southeast. Holes A20-173 and A20-175 have improved our geological model of the central portion of West Ayawilca with good grades also intersected in these holes.“
“We await with much anticipation the assay results for the eleven pending drill holes, and we still have a handful more holes to drill. The receipt of results from the lab continues to be slow due to coronavirus pandemic protocols in Peru. Drilling will continue for the next few weeks, focusing on expanding our high-grade indicated resources at South Ayawilca that will be reflected in an updated Preliminary Economic Assessment (PEA) planned for mid-2021.â€
“Ayawilca contains one of the higher-grade zinc resources anywhere in the world, and we are very excited to see zinc prices reflect the lack of significant new supply. We strongly believe that Ayawilca is perfectly positioned to take advantage of current positive market sentiment towards base metals.”

- 13.7 metres @ 15.9% zinc & 26 g/t silver from 282.6 metres depth;
These are partial results only – significant visible zinc and iron sulphide mineralization has been observed from 309 metres depth (end of reported interval above) to the contact with the underlying phyllite at 357 metres depth – assay results for this interval are pending;
Mineralization is associated with gently dipping sulphide rich “mantos†hosted by limestones;
True thicknesses of the manto intersections are estimated to be at least 90% of the downhole thicknesses.
Hole A20-169 (West Ayawilca)
- 0.9 metres @ 13.7% zinc, 0.6% lead & 133 g/t silver from 108.8 metres depth; and
- 1.1 metres @ 12.4% zinc, 2.1% lead & 147 g/t silver from 136.0 metres depth; and
- 1.1 metres @ 18.8% zinc, 5.0% lead & 172 g/t silver from 190.0 metres depth; and
- 0.7 metres @ 15.2% zinc, 1.3% lead & 71 g/t silver from 210.5 metres depth; and
- 1.2 metres @ 22.7% zinc, 3.9% lead & 190 g/t silver from 356.8 metres depth.
Mineralization in hole A20-169 is vein style – these veins have unknown true thicknesses.
Hole A20-170 is an infill hole within the overall footprint of the inferred resource at South Ayawilca. Hole A20-169 is a step-out hole 75 metres west of the existing inferred resource at West Ayawilca – this hole intersected several high-grade but narrow zinc-silver-lead veins. So far in the drill program, approximately 2,500 metres have been completed in seven drill holes (see Figure 1 for a map of drill holes). The overall program is now expected to extend into early 2021. Several drill targets still remain to be tested, including the large area between West and South Ayawilca which has seen limited past drilling.

Tinka Resources Limited - update on exploration activities
September 9, 2020
Vancouver, Canada – Tinka Resources Limited (“Tinka†or the “Companyâ€) (TSXV & BVL: TK) (OTCPK: TKRFF) is pleased to provide an update on exploration activities at its 100%-owned Ayawilca zinc-silver project in Peru. Preparations are underway for a ~7,000 metre drill program consisting of approximately 20 diamond drill holes. Three drill rigs are expected to mobilize to site and commence drilling by the end of September 2020. The program will target areas where earlier drilling identified high grade zinc and silver mineralization, often outside of the known resources. Most of these zones lie adjacent to the Colquipucro Fault, an important north-northwest trending regional structure (Figures 1 and 2). It is anticipated that the drill program will be completed in early 2021, subject to potential delays as a result of the COVID-19 pandemic. A framework of stringent health and safety measures has been implemented, which includes protocols to prevent the spread of COVID-19, and, as a result, the timing of the start and completion of the drill program may vary.
The 2020 drill program will focus on a combination of resource step-out drilling in areas where mineralization remains open to increase resources, and infill drilling to upgrade the category of the Ayawilca resources in areas of high grade mineralization. Priority targets include:
West Ayawilca: Step-out holes down-dip of previous drill hole intersections, which include 10 metres grading 665 g/t silver, 1.4% zinc and 1.9% lead in drill hole A18-131 (not included in resource estimate) and 31.9 metres grading 9.6% zinc & 19 g/t silver in hole A18-118 (included in inferred resource) (see news releases dated October 15, 2018, and May 24, 2018).
West Ayawilca: Infill drilling to upgrade Inferred resources into Measured or Indicated categories (approximately 50% of program). Current Inferred resource includes drill hole intercepts such as 10.4 metres grading 44.0% zinc & 43 g/t silver in hole A18-129 (see news release dated June 26, 2018).
The Colqui Silver Zone: Step-out holes are planned to test for possible down-dip extensions of the oxide silver mineralization. Previous drill hole highlights include 128 metres grading 91 g/t silver in CDD4, and 52 metres grading 155 g/t silver in hole CDD43 (see Figure 3).
The Ayawilca Zinc Zone (sulphide) contains an estimated 1.8 billion pounds zinc and 5.8 million ounces silver in the Indicated category, and 5.6 billion pounds zinc and 25.2 million ounces silver in the Inferred category (see news release dated November 26, 2018). The Colqui Silver Zone (oxide) contains an estimated 14.3 million ounces silver in the Indicated category and 13.2 million ounces silver in the Inferred category, with mineralization starting from surface (see link to Technical Report dated July 2, 2019).

Tinka Provides Update On Peru Activities
Vancouver, Canada – Tinka Resources Limited (“Tinka” or the “Company”) (TSXV & BVL: TK) (OTCPK: TKRFF) is pleased to advise that the Company’s employee in Peru who tested positive to COVID-19 as disclosed on March 26th has now fully recovered from the virus and is in good health. To the best of our knowledge, there are no other cases of COVID-19 infection amongst Tinka employees or in the communities associated with our activities in the Pasco region of Peru.
The state of emergency in Peru has been in place since March 15th and is now extended until May 24th following a recent announcement by the government of Peru. Mining is one of the key sectors of the Peruvian economy, and the government has indicated that mining will be one of the first industries to recommence after the lockdown eases, using a phased stage approach. The restart in mining will begin with large operations and strategic mining projects under construction, while exploration and development projects like Ayawilca will commence a short while after.
Tinka’s employees in Peru have been in self-isolation during the lockdown, while our community relations team has continued to engage with the local communities in preparedness for an increase in work activities to follow. Prior to the restart of exploration activities, Tinka will be required (along with all resource companies) to obtain approval from government bodies for its own health protocols. The protocols will incorporate self distancing, disinfection procedures and COVID-19 testing among other measures. The Company is planning for the next exploration phase at Ayawilca to commence during the latter part of 2020, which is expected to include at least 7,000 metres of infill and step-out drilling, with a focus on growing and upgrading the high-grade zinc-silver resources at West and South.
Tinka is well funded, following the investment by Buenaventura and Sentient in January 2020, and has no debt. The Company has also taken steps to reduce its overhead costs to match reduced levels of activities.
President and CEO of Tinka, Dr. Graham Carman, stated: “Tinka’s fundamentals remain strong following the strategic financing completed early in 2020, underpinned by our 100% owned Ayawilca zinc-silver project. The safety of our employees and their families and our nearby communities remains our highest priority, and our Peruvian management team is to be congratulated for its decisive response to prevent the spread of COVID-19 at our project camp. Corporate administration costs have been reduced during this lockdown period as we aim to preserve the Company’s cash position. We look forward to updating the market as our field activities in Peru recommence in coming weeks.”

VANCOUVER, Oct. 8, 2019 /PRNewswire/ - Tinka Resources Limited ("Tinka" or the "Company") (TSXV & BVL: TK) (OTCPK: TKRFF) is pleased to announce assay results for three recent drill holes at the Company's 100%-owned Ayawilca project in Peru.
Hole A19-165 has returned some of the best zinc intersections ever drilled at South Ayawilca, both from within and immediately outside of the zinc resource boundary. The hole intercepted four separate, gently dipping mineralized zones with downhole thicknesses of between 9 and 29 metres and grading between 11.8% and 14.0% zinc, within a cumulative downhole interval of 170 metres (note: downhole thicknesses approximate true thicknesses in this hole). A summary of the assays from the four intervals in hole A19-165 is provided below.
Hole A19-167, a recently completed and deepened 2017 drill hole, intersected very high grade silver mineralization (>1,000 g/t Ag) accompanied by base metals (14.5% Zn, 0.3% Pb) over a narrow 1.7 metre interval approximately 100 metres beneath the existing Zinc Zone resource, within a wider zone of lower grade silver mineralization associated with strongly altered Pucará limestone (see Figure 1). The silver intersection in hole A19-167 lies 80 metres from the silver intersection in hole A19-163 (13.9 metres at 130 g/t Ag; see Sep. 5, 2019, news release). This new "Silver Zone" discovery supports Tinka´s view that Ayawilca still has significant exploration potential, including upside for precious metals.
Key highlights from recent drill holes at South Ayawilca:
Zinc Zone:
Hole A19-165
9.0 metres @ 11.9% zinc & 18 g/t silver from 117.2 metres; and
25.9 metres @ 11.8% zinc, 0.2% lead, 23 g/t silver & 325 g/t indium from 167.8 metres, including
4.0 metres @ 24.6% zinc, 33 g/t silver, 0.1% lead & 475 g/t indium from 169.1 metres;
7.0 metres @ 18.9% zinc, 42 g/t silver, 0.5% lead & 584 g/t indium from 178.4 metres; and
28.7 metres @ 14.0 % zinc, 14 g/t silver, 0.1% lead & 101 g/t indium from 214.6 metres, including

0.95 metres @ 44.1% zinc, 90 g/t silver, 0.3% lead & 867 g/t indium from 285.45 metres.
Hole A19-166
0.8 metres @ 38.5% zinc, 117 g/t silver & 0.4% lead & 442 g/t indium from 122.3 metres; and
0.85 metres @ 31.1% zinc, 40 g/t silver & 311 g/t indium from 138.7 metres.
Silver Zone:
Hole A19-167 (extension of drill hole A17-064 from 361 metres depth)
7.3 metres @ 4.9% zinc, 366 g/t silver & 0.5% lead from 412.7 metres, including
*1.7 metres @ 14.5% zinc, 1,130 g/t silver & 0.3% lead from 412.7 metres; and
7.85 metres @ 6.1% zinc, 150 g/t silver & 0.8% lead from 434.45 metres, including
0.9 metres @ 21.7% zinc, 415 g/t silver & 3.0% lead from 434.5 metres.
Note: True thicknesses of the Zinc Zone intersections are estimated to be approximately equal to the downhole thicknesses in hole A19-165 and at least 85% of the downhole thicknesses in A19-166. The true thickness of the Silver Zone intersections in A19-167 cannot be determined at this time as insufficient data is available.
Dr. Graham Carman, Tinka's President and CEO, stated: "Hole A19-165 is an exceptional drill hole with four separate mineralized intervals with outstanding zinc grades over significant thicknesses, confirming continuity of the mineralization and increasing confidence in our geological model. Zinc grades in the upper two zones were higher than predicted by the resource model (see Figure 1). Multiple phases of zinc mineralization, as indicated by spectacular colour banding of the sphalerite crystals, indicate that the mineralization at Ayawilca was multi-phase while also highlighting the fact that each phase added to the zinc grade of the deposit (see Figures 2 and 3)".
"We are also excited by the high grade Silver Zone discovery in hole A19-167, originally a 2017 Tinka drill hole that was recently deepened to test extensions of the silver mineralization encountered in hole A19-163. The success of A19-167 proves that Ayawilca has very high -grade silver mineralization which is believed to have developed around the edge of the Ayawilca Zinc Zone. This recent discovery offers a new exploration target and potentially significant precious metal upside to supplement the very large zinc resource."
"The 2019 drill program at South Ayawilca is greatly improving our understanding of the structural and lithological controls of the high grade zinc mineralization. Drill hole A19-166 was drilled at a very shallow angle and confirmed the geometry of a locally overturned anticline which has acted as a structural trap for the zinc mineralization. An additional drill hole, A19-168 was recently collared, which will act as an additional infill hole and provide further geotechnical information."
Notes to Figure 1:
The zinc block model is based on the base case mineral resource estimate at a US$55/t cut off (Nov. 26, 2018). High grade (>US$100/t or >6.5% ZnEq) zinc resource blocks are coloured red, lower grade blocks are coloured in green (>US$55/t or 3.6% ZnEq) and blue coloured blocks are below the cut off.
The NSR value 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$1.15/lb Zn, US$300/kg In, US$15/oz Ag, and US$1.0/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$4.70 per % Pb, US$0.18 per gram In, and US$0.22 per gram Ag.
The NSR value was calculated using the following formula:
NSR = [Zn(%)*US$15.34+Pb(%)*US$4.70+In(g/t)*US$0.18+Ag(g/t)*US$0.22].
The ZnEq value was calculated using the following formula: ZnEq = NSR/US$15.34.
Details of assay intervals within the core photo above:
179.3-181.3 metres (sample 47295): 2.0 metres grading 27.8% Zn, 23 g/t Ag, 0.02% Pb, 733 g/t In
181.3-182.1 metres (sample 47296): 0.8 metres grading 5.9% Zn, 13 g/t Ag, 0.02% Pb, 95 g/t In

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 laboratories in Lima for assay in batches. Standards and blanks are inserted by Tinka into each batch prior to departure from the 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.

Tinka Drills 20 Metres At 15% Zinc And 10 Metres At 17% Zinc As Exploration Continues At Ayawilca For Additional High Grade
July 29th, 2019
Vancouver, Canada – Tinka Resources Limited (“Tinka” or the “Company”) (TSXV & BVL: TK) (OTCPK: TKRFF) is pleased to announce assay results for four new drill holes at the Company’s 100%-owned Ayawilca Property in central Peru. Three holes were drilled at West Ayawilca and one hole was drilled at South Ayawilca.
Hole A19-162 at South Ayawilca intercepted thick zones of zinc mineralization within the existing resource, as expected, however the zinc grades are much higher than expected compared with adjacent holes and are approximately double the average grade of the Ayawilca Zinc Zone resource. Hole A19-162 also intercepted a weakly mineralized limestone layer in the lower portion of the hole, significant in the fact that it supports the Company’s thesis of possible limestone-hosted zinc mineralization lying beneath the existing resource.
Key Highlights from recent drilling
Hole A19-162 (South Ayawilca):
25.4 metres grading 11.6% zinc, 14 g/t silver and 223 g/t indium from 162.6 metres, including
10.0 metres grading 17.2% zinc, 14 g/t silver and 363 g/t indium from 176.0 metres; and
19.6 metres grading 15.2% zinc, 9 g/t silver and 212 g/t indium from 247.4 metres, including
7.2 metres grading 21.8% zinc, 12 g/t silver and 354 g/t indium from 259.8 metres;
Hole A19-159 (West Ayawilca):
11.2 metres grading 11.8% zinc and 24 g/t silver from 243.1 metres depth (resource infill);
Note: True thicknesses of the zinc intersections are estimated to be at least 85% of the downhole thicknesses. Mineralization in the above intervals are relatively flat-dipping replacement zones hosted by limestone and/or sandstone.

Tinka Announces Filing of NI 43-101 Technical Report on the Ayawilca Property, Peru
January 9th, 2019
Vancouver, Canada - Tinka Resources Limited (“Tinka” or the “Company”) (TSXV & BVL: TK) (OTCPK: TKRFF) Vancouver, Canada announces that the Company has filed an updated independent National Instrument 43-101 Technical Report (the “NI 43-101 Technical Report”) on the Mineral Resource Estimate for the Ayawilca Property, Department of Pasco, Peru, in support of the Company’s news release dated November 26, 2018 (the “News Release”). There are no material differences in the NI 43-101 Technical Report from the information disclosed in the News Release.
Part of the Zinc Zone Mineral Resource is now classified as Indicated, incorporating a higher-grade portion of the deposit. In addition, the updated Inferred Mineral Resource is of a similar size and grade to the previous Zinc Zone resource reported in November 2017. The updated Tin Zone Inferred Mineral Resource is also substantially larger. This resources update follows a very successful drilling program, with the Company completing approximately 20,000 metres during 2018.
Key Highlights of Updated Mineral Resources at Ayawilca
Indicated Zinc Zone Mineral Resource of 11.7 million tonnes grading 6.9% zinc, 0.16% lead, 84 g/t indium and 15 g/t silver (8.1% zinc equivalent “ZnEq”), containing:
1.8 billion pounds of zinc;
983 tonnes of indium;
5.8 million ounces of silver; and
42 million pounds of lead.
Inferred Zinc Zone Mineral Resource of 45.0 million tonnes grading 5.6% zinc, 0.23% lead, 67 g/t indium and 17 g/t silver (6.7% ZnEq), containing:

A followup interview about the November 28th, 2018 PR
With the Ayawilca Resource Updated, Next Step is a PEA Tinka Resources recently updated the zinc and tin mineral resource estimates for its Ayawilca project in Peru. This was the fourth zinc resource on Ayawilca and there has been tremendous growth in the total resources as a result of about 67,000 metres of diamond drilling. Of note in the most recent zinc resource was that a significant portion of the resource is now categorized as "Indicated".
With the updated and upgraded zinc resource, Tinka is now positioned as having one of the biggest undeveloped zinc resources controlled by a junior mining company. Moreover, the Ayawilca project is located in a mining-friendly jurisdiction and it has good infrastructure (road access, power, water). Ayawilca's zinc grades also compare favourably to the grades at existing and planned zinc mines in Peru. For all of these reasons, there has been significant interest from other mining companies in the Ayawilca project. Tinka's CEO, Graham Carman, discusses this in his most recent interview, which you can view by clicking on the graphic below.
Ken Engquist a Strong Addition to the Tinka Team
Tinka is now commencing work on the maiden Preliminary Economic Assessment ("PEA") on Ayawilca. Wood (formerly Amec Foster Wheeler) in Lima, Peru, has been engaged to lead the PEA. In conjunction with the commencement of the PEA, Tinka augmented its technical team by bringing on Ken Engquist. Mr. Engquist has a wealth of mining engineering experience. Recently, he has been involved with engineering studies for Arizona Mining's Hermosa project, which is now owned by South32. He has also been involved in other big base metals projects, including Nevsun's Timok copper project and Turquoise Hill/Rio Tinto's Oyu Tolgoi copper project. We believe Mr. Engquist is a great addition to the team. The news release announcing the PEA and hiring of Mr. Engquist can be found at the end of this email.
Market Fundamentals
If you had told me at a year ago that zinc inventories would drop over 50% and yet zinc prices would fall substantially, I would not have believed it. Likewise, I would not would have believed a prediction that Tinka would grow its zinc resources by over 30% and yet be trading at less than half of where the shares were trading a year ago. But, that is the market we have found ourselves in. Strong fundamentals (zinc cash premiums hitting new records - see chart below) are being overshadowed by negative market sentiment that has been largely driven by the trade war between the United States and China.
This past weekend's G20 dinner meeting between the two countries brought some glimmers of hope that the trade war will be resolved in the coming months. Hopefully that is the case and market conditions are more bullish in 2019, as trade wars are generally bad for everybody. Irrespective of whether a resolution is reached or not, it is important to remember that zinc fundamentals remain very tight and inventories can't drop much more. Something has to give and a number of analysts we have spoken with recently expect another leg up in zinc prices in 2019.
Some new zinc supply is coming on stream, albeit slowly, but the other reality is that mining companies are looking for new projects to fill the pipeline. We believe that Ayawilca is a great project for development and look forward to the results of the PEA. In the meantime, the company has a strong balance sheet and a path forward to add value to the Ayawilca project through de-risking and additional exploration.
We appreciate your interest and support, especially during these trying markets. Please don't hesitate to reach out with any questions or comments.

Tinka Reports A Substantial Increase In Zinc And Tin Mineral Resources At Ayawilca
November 26th, 2018
Vancouver, Canada – Tinka Resources Limited (“Tinka” or the “Company”) (TSXV & BVL: TK) (OTCPK: TKRFF) is pleased to announce an updated Mineral Resources estimate for its 100%-owned Ayawilca zinc and tin deposits in Peru. Part of the Zinc Zone Mineral Resource is now classified as Indicated, incorporating a higher-grade portion of the deposit. In addition, the updated Inferred Mineral Resource is of a similar size and grade to the previous Zinc Zone resource reported in November 2017. The updated Tin Zone Inferred Mineral Resource is also substantially larger. This resources update follows a very successful drilling program, with the company completing approximately 20,000 metres during 2018.
Key Highlights of Updated Mineral Resources at Ayawilca
--- Indicated Zinc Zone Mineral Resource of 11.7 million tonnes grading 6.9% zinc, 0.16% lead, 84 g/t indium and 15 g/t silver (8.1% zinc equivalent “ZnEq”), containing:
- 1.8 billion pounds of zinc;
- 983 tonnes of indium;
- 5.8 million ounces of silver; and
- 42 million pounds of lead.
--- Inferred Zinc Zone Mineral Resource of 45.0 million tonnes grading 5.6% zinc, 0.23% lead, 67 g/t indium & 17 g/t silver (6.7% ZnEq), containing:
- 5.6 billion pounds of zinc;
- 3,003 tonnes of indium;
- 25.2 million ounces of silver; and
- 230 million pounds of lead.
--- Inferred Tin Mineral Resource of 14.5 million tonnes grading 0.63% tin, 0.21% copper, & 18 g/t silver (0.70% tin equivalent “SnEq”), containing:
201 million pounds of tin;
67 million pounds of copper; and
8 million ounces of silver.
The Tin Zone and Zinc Zone resources do not overlap. The Mineral Resources are reported above an NSR cut-off value of US$55/tonne, as estimated by Roscoe Postle Associates Inc. (RPA Inc.) of Toronto, Canada.
Dr. Graham Carman, Tinka’s President and CEO, stated: “We are very pleased with the updated mineral resources estimation, as the Ayawilca deposit now represents one of the largest zinc resources held in a non-producing resources company. Ayawilca has for the first time, a high-grade Zinc Zone resource in the Indicated category containing 1.8 billion pounds of zinc (24% of the total zinc inventory), as well as an Inferred resource containing 5.6 billion pounds of zinc (76% of the total zinc inventory). Zinc resources were able to be partially upgraded to Indicated in those areas due to infill drilling at West and South Ayawilca in 2018. In addition, the Tin Zone resource has increased by 38% and now contains over 200 million pounds of tin. The updated Tin Zone resource is believed to be the largest undeveloped tin resource outside of a producing camp in Peru.”
“Tinka has had a very successful year at Ayawilca, expanding and upgrading the resources. We now look forward to completing our maiden PEA in the first half of 2019. Additional potential still exists for resource growth at Ayawilca, with additional step-out and deeper exploration drilling planned for 2019. The Company’s work programs are fully funded into the foreseeable future, with C$13 million in cash and no debt as at the end of September 2018.”

Tinka Continues To Expand Zinc Mineralization And Discovers High-Grade Silver Veins At Ayawilca Peru
October 15th, 2018
Vancouver, Canada – Tinka Resources Limited (“Tinka” or the “Company”) (TSXV & BVL: TK) (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:
1.2 metres at 13.8% zinc, 0.8% lead, 817g/t silver and 64g/t indium from 156.3 metres depth.
A18-158:
1.5 metres at 9.6% zinc, 1.2% lead and 32g/t indium from 458.4 metres depth.
A18-125:
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’ hosted 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 test outcropping silver-lead-zinc carbonate veins at the “Vetas” area, a target drilled for the first time in 2018. High-grade silver intercepts 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:
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 resources (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 appointed as independent consultant to undertake 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.

Tinka Resources plans on meeting the high demand for zinc.
Sep 12, 2018
The Ayawilca Property is located 200 km northeast of Lima in the Department of Pasco, Central Peru, at altitudes of between 3,800 and 4,300 metres. The Property is 40 km northwest of the world-class Cerro de Pasco zinc-lead-silver mine, and 100 km south of the giant copper-zinc Antamina mine. Tinka owns 100% of the contiguous 150 km2 mining concessions at Ayawilca.
The company is focusing on growing the Ayawilca Mineral Resources. During 2017, around 20,000 metres of diamond drilling were completed at Ayawilca, and by December 2017 the drill program is ongoing. A new zinc discovery was made during 2017 at South Ayawilca that has significantly increased the resources at the Property. As announced on November 8, 2017, the Company announced a 130% increase to the previous zinc resources.

Tinka Resources to update resource and explore new discoveries after drilling 20,000m
Published on Sep 26, 2018
Tinka Resources Ltd (CVE:TK) chief executive Dr Graham Carman updates Proactive Investors on drilling results flowing from the company's flagship Ayawilca zinc and tin project in Peru. This year alone Tinka has drilled around 20,000 metres across the project area, adding to 46,000 metres drilled since the initial discovery. As a result, new discoveries have been made. "It's one of the largest zinc resources in the world, in a junior company, and we think it's going to be a mine," says Carman. A resource update is slated to be announced in a matter of weeks, with a PEA planned for the start of next year.

Tinka Reports Additional Step-Out & Infill Drill Holes At Ayawilca And Highlights Upper Manto Discovery
September 18th, 2018
Vancouver, Canada – Tinka Resources Limited (“Tinka” or the “Company”) (TSXV & BVL: TK) (OTCPK: TKRFF) is pleased to announce results for twelve drill holes from the Company’s ongoing resource expansion and confirmation drill program at the 100% owned Ayawilca project, central Peru.
Key Highlights:
Five resource step-out drill holes at West, South, Central and Camp areas have all intersected significant zinc mineralization hosted mostly by Pucara limestone, the main host of the zinc sulphide mineralization;
Hole A18-148 intersected high-grade zinc (5.5 metres grading 10% zinc) 100 metres further east of the current resource at the Central area, with extensions to be tested later in 2018;
Hole A18-146 intersected high-grade zinc and silver mineralization (1.7 metres grading 27% zinc & 1520 g/t silver from 57 metres depth) in an ‘Upper Manto’ hosted by sandstone at the South area, above and lateral to the known limestone hosted resource. The Upper Manto has been observed in other drill holes and is considered significant due to its shallow depth and proximity to existing resources;
Hole A18-150 (9.6 metres grading 6% zinc) and adjacent hole A18-154 have extended known mineralization at the West area 120 metres to the northeast – mineralization remains open;
Seven resource infill holes are also reported from the West and South areas, drilled to improve the Company’s geological model and to target additional zinc mineralization at depth;
Tinka now plans to update the Ayawilca resource estimate in Q4 2018, while step-out drilling continues.
Graham Carman, Tinka´s President and CEO, stated: “The step-out drill hole results reported in this release are very positive, and show that the footprint of zinc mineralization at Ayawilca is getting larger. So far in 2018 we have discovered several new areas of significant zinc mineralization, including:
thick and high-grade intersections up to 150 metres to the northwest of the West Ayawilca resource (e.g., hole A18-118);
the Camp area, which connects West mineralization with the Central area (e.g., holes A18-130 & 134);
repetitions of mineralized limestone beneath lenses of phyllite at West Ayawilca which can host exceptional zinc grades (e.g., 10.4 metres grading 44% zinc, hole A18-129);
shallow zinc sulphide mineralization hosted by the overlying sandstone within a laterally extensive Upper Manto; and
extensions to the mineralization east of the Central and West areas (e.g., holes A18-148 & A18-150);
“Zinc mineralization still remains open along strike and down dip in several directions, while other prospective areas such as Zone 3 continue to offer additional potential.”
