Tinka Resources Limited announced results for four drill holes from the ongoing resource expansion and exploration drill program at the Company's Ayawilca project in Peru. Highlights include a new intersection of high-grade silver mineralization from the ‘Silver Zone' in hole A23-220 located on the edge of the massive sulphide ‘Zinc Zone' at South Ayawilca. The Silver Zone has been reinterpreted with data from current and previous drill holes to have been emplaced along a northeast-trending sub-vertical fault bordering the massive sulphides.

High-grade, structurally controlled, silver mineralization is confirmed along a strike length of approximately 250 metres, open along-strike in both directions and at depth. Key Highlights: New ‘Silver Zone' drill hole intercepts: Hole A23-220: 29.5 metres at 182 g/t silver, 2.4% zinc & 0.8% lead from 289.65 metres depth, including; 7.1 metres at 604 g/t silver, 2.7% zinc & 1.6% lead from 310.9 metres depth, including; 0.65 metres at 2,565 g/t silver, 4.2% zinc & 5.7% lead from 313.7 metres depth. The Silver Zone is interpreted as a northeast-trending structure on the edge of the Zinc Zone sulphides along a strike length of approximately 250 metres.

A follow-up drill hole targeting a 100-metre extension of the Silver Zone is in progress. Mineralization is associated with a low abundance of sulphide minerals including ‘ruby silvers' with sphalerite and galena in a carbonate-rich vein matrix. Hole A17-095: 8.7 metres at 135g/t Ag, 1.1% Zn & 0.6% Pbfrom 307.3 metres depth.

Silver Zone intercepts previously released: Hole A17-072: 11.5 metres at 781 g/t silver, 2.9% zinc & 2.3% lead from 294.5 metres depth, including; 2.0 metres at 3,167 g/t silver, 5.6% zinc & 5.5% lead from 302.0 metres depth. Hole A19-167: 29.6 metres at 152 g/t silver, 3.1% zinc & 0.4% lead from 412.7 metres depth in hole A19-167, including; 7.3 metres at 366 g/t silver, 4.9% zinc & 0.5% lead from 412.7 metres depth, including; 1.7 metres at 1,130 g/t silver, 14.5% zinc & 0.3% lead from 412.7 metres depth. True thicknesses of the intercepts in the Silver Zone are estimated to be 65-75% of the downhole thicknesses.

Geological discussion of the ‘Silver Zone': The new high-grade drill intercept in A23-220 has led to a reinterpretation of silver-rich intersections in several other holes at Ayawilca which have a low sulphur content with relatively minor sphalerite and galena but contain visible silver sulphides (including pyrargyrite also known as ‘ruby silver') and abundant hydrothermal carbonate. Following a detailed review of past drill holes, this style of mineralization is believed to be structurally controlled and emplaced along a northeast-trending fault zone (the ‘060 Fault') on the northern flank of the massive sulphide mineralization at South Ayawilca. Four drill holes are interpreted to have intersected the Silver Zone along the 060 Fault within the favourable Pucara limestone host.

These Silver Zone drill intersections include: Hole A23-220:29.5 metres at 182 g/t Ag, 2.4% Zn & 0.8% Pb from 289.65 metres (including 7.1 m at 604 g/t Ag 2.7% Zn & 1.6% Pb from 310.9 metres (new drill hole); Hole A17-095:8.7 metres at 135 g/t Ag, 1.1% Zn & 0.6% Pb from 307.3 metres (new intercept in past hole); Hole 17-072:11.5 metres at 781 g/t Ag, 2.9% Zn & 2.3% Pb from 294.5 metres (including 2.0 m at 3,167 g/t Ag, 5.6% Zn and 5.5% Pb from 302 metres); Hole A19-167: 29.6 metres at 152 g/t Ag, 3.1% Zn & 0.4% Pb from 412.7 metres (including 7.3 m at 366 g/t Ag, 4.9% Zn & 0.5% Pb from 412.7 metres). True thicknesses of the Silver Zone intercepts are estimated to between 65-75% of the downhole thicknesses. The Silver Zone mineralization has so far been identified along a 250 metres strike length of the northeast-trending structure.

A follow-up hole to A23-220 is in progress to test a further 100 m strike extension of the silver mineralization in hole A23-223. A cross section of the Silver Zone mineralization intersected in hole A23-220. A longitudinal section along the 060 Fault highlights the along-strike potential of the Silver Zone.

The Silver Zone mineralization is interpreted to have occurred late-stage in the mineralization history at Ayawilca (i.e., post main-stage zinc). The silver-rich mineralization is relatively low in total sulphide content (<20 vol.%). The main gangue minerals are complex hydrothermal carbonates containing variable amounts of Mn, Mg and Fe and are cream to pale brown in colour.

The texture of the hydrothermal carbonates in the high-grade silver zones is indicative of open space filling (i.e., with banded and drusy carbonate textures). Complex carbonates also replace the original limestones on the margins of the fault structure. Core photos of the typical Silver Zone mineralization.

Other new Zinc Zone drill results from South Ayawilca include: Hole A23-218: 66.85 metres at 6.4% zinc from 229.0 metres depth, including; 11.9 metres at 11.4% zinc from 231.4 metres depth; and 7.1 metres at 14.8% zinc from 272.9 metres depth. Hole A23-220: 10.55 metres at 9.6% zinc from 269.45 metres depth. Hole A23-221: 13.8 metres at 6.8% zinc from 290.0 metres depth.

True thicknesses of the mineralized intercepts are estimated to be between 65-75% of the downhole thicknesses.
