Project: Ayawilca

Country: Peru

Ownership: 100 percent

Resources: Inferred: 13.3 million tonnes at 5.9 percent zinc, 0.2 percent lead, 68 g/t indium, 14 g/t silver: Colquipucro Silver Oxide Deposit: 7.1 million tonnes at 118 g/t silver

  • Tinka Resources announced initial 43-101 resource estimate on the Ayawilca zinc/silver/indium deposit on its 100 percent owned Colquipucro project. The Ayawilca-Colquipucro project is located within a 150 kilometer long zinc belt in west-central Peru hosting a number of significant zinc deposits including Antamina, Cerro de Pasco and Colquijirca. Also this week the Company announced Indium results from previously released holes.
  • The initial inferred resource totals 13.3 million tonnes grading 5.9 percent zinc,0.2 percent lead, 68 g/t silver and 14 g/t silver using a US$ 60 cut-off grade. Metal prices used in the resource estimation are $1.20 per pound zinc, US$ 550 per kilogram indium, US$ 24.00 per ounce silver and $1.10 per pound lead. The resource was calculated using 18,634 meters of core from 43 drill holes. High values were cut to 25 percent zinc, 500 g/t indium and 100 g/t gold before compositing to two meter lengths for the block model.
  • Highlights from the previously released holes (2013) now including Indium assays are: 212.9 meters grading 5.3 percent zinc, 83 g/t indium and 15 g/t silver, 148.5 meters at 4.33 percent zinc, 55 g/t indium and 10 g/t silver. (Indium prices are currently approximately $17 per ounce or equal to silver). True widths are believed Company be at least 75 percent of the reported core length.
  • The 2011 Ayawilca discovery was blind gravity geophysical target covered by 150 meters of barren sandstone located 2 kilometers south of the Company’s Colquipucro oxide silver resource.  The semi massive mineralization occurs as gently dipping replacement zones within a sedimentary breccia, siltstone, shale and limestone horizon.  The deposit also includes a deeper copper/tin zone with assays up to 76 meters grading 0.36 percent copper and 0.21 percent tin. (Tin price is currently $8.21 per pound)


Early Discovery Holes: 4.0 meters at 6.75 percent zinc, 17 g/t silver (Oct 2011); 213 meters at 5.3 percent zinc, 15 g/t silver (2013)

Holes including Indium: 212 meters at 5.3 percent zinc, 83 g/t indium, 15 g/t silver; 148 meters at 4.33 percent zinc, 55 g/t indium and 10 g/t silver
