VANCOUVER, Nov. 3, 2017 /PRNewswire/ - Tinka Resources Limited ("Tinka" or the "Company") (TSXV & BVL: TK) (OTCPK: TKRFF) is pleased to announce tin assay results for eight drill holes from the South Ayawilca zinc discovery area in central Peru (zinc intercepts from these holes were previously reported earlier in 2017). Tin mineralization at Ayawilca is predominantly in the form of cassiterite (SnO2), disseminated in flat-lying massive to semi-massive pyrrhotite 'mantos' which are physically separated from the zinc zones. Tin at South Ayawilca connects and expands the known tin mineralization at Central Ayawilca, which includes drill intercepts of 50.5 metres grading 1.23 % tin & 0.16 % copper in hole A15-040, and 50.0 metres grading 0.52 % tin & 0.25 % copper in A15-039 (News Releases October 13, 2015 & September 29, 2015) (see Figure 1).
Assays for four new zinc drill hole intercepts are also reported below. An updated zinc and tin resource estimate is expected shortly, with results for all the holes to be included in the resource update now reported (up to hole A17-098). Two drill rigs continue to test new targets at Ayawilca - current holes are A17-105 and A17-091A (Valley and Zone 3 areas, respectively) with several more holes planned before the end of the year.

Note: A cut-off of 0.2% tin over 6 metres has been applied.
Dr. Graham Carman, Tinka´s President and CEO, stated: "Tinka is focusing on realizing the potential of the extensive high-grade zinc mineralization at Ayawilca. However, we believe the project also offers additional upside for other commodities, especially for tin, which occurs in separate mineralized bodies to the zinc. Tin intercepts reported here from South Ayawilca are believed to connect with the Central Ayawilca tin resource, extending the footprint of the tin mineralization by several hundred metres. Tin is currently trading at ~6 times the price of zinc, and ~3 times the price of copper on the London Metals Exchange, so these tin intercepts are potentially significant to the project. We look forward to updating our zinc and tin resources very shortly, which will include the 2017 South Ayawilca discovery."
Zinc assays for four new drill holes from the Ayawilca South and Valley zones are also reported here, with all holes intersecting significant zinc mineralization. Two holes drilled at the Valley area targeted previously untested magnetic anomalies. Results have confirmed the presence of zinc mineralization at or near the base of the host carbonate sequence. Two holes tested extensions of South Ayawilca (A17-095 & 098). See Figure 1 for drill holes locations.

Dr. Graham Carman, Tinka´s President and CEO, continued: "Drill results from the Valley area, about 1 kilometre north of the Ayawilca zinc zone resources, indicate that the Ayawilca zinc system is very large and has significant potential to grow. We plan to continue drill testing for new zinc discoveries even as an updated resource estimate is being finalized. This strategy allows Tinka to pursue the blue-sky potential of Ayawilca, while simultaneously working towards de-risking the known resources."
Drill Progress
Seven drill holes from South and Central Ayawilca have assays pending (A17-097, 099 to 104). Two holes are currently in progress at Zone 3 (A17-091A) and Valley (A17-105).
True thicknesses of the zinc and tin intersections are estimated to be at least 85% of the downhole thickness, except where otherwise noted in footnotes to Table 1 and Table 2. All significant zinc (lead, silver, indium) intercepts of the 2017 program are summarized in Table 1 with the strongest intercepts in bold text. Significant tin (copper, silver) intercepts of the 2017 program are summarized in Table 2. Table 3 summarizes drill collar information.
