Inca Minerals Limited received assay results for a detailed mapping and channel- sampling program of recently opened small underground mine workings (Mine 4494-4496) located over vein HV-01, within the Callancocha Structure Zone, Riqueza Project. The mine workings follow vein HV-01 over a combined distance of 30m. Follow-up channel sampling was also undertaken at a previously sampled mine working (Mine 4489) over vein HV-02 (ASX announcement 15 December 2017). Mine 4494-4496 and Mine 4489 are located in close proximity to Mine 4479 and to the two trenches that produced very strong and open mineralization. The assay results from channel sampling veins HV-01 and HV-02 are very encouraging. Peak values include: 15.45% Zn (Sample IM-000492) channel length 0.44m of HV-01. 256g/t Ag (Sample IM-000484) channel length 0.37m of HV-01. 14.96% Pb (Sample IM-000477) channel length 0.38m of HV-02. The top-5 Zn values of 27 samples in total (from both veins) are greater than 6.66% and average 10.44% Zn. The top-5 Ag values are greater than 167g/t and average 200.2g/t Ag. The top-5 Pb values are greater than 9.21% and average 12.15% Pb. Detailed mapping of mineralisation exposed in the mine faces reveals that the veins themselves comprise interweaving zones of ore-forming minerals galena, sphalerite and smithsonite, varying in form from crustiform bands, veinlets, stockworks, matrix infill and disseminations. Gangue minerals include calcite and barite varying in form from masses, bands and veinlets. As previously reported, the grades now being achieved through direct sampling both veins HV-01 and HV- 02 are significantly higher than the grades achieved in drilling. The latest set of results, subject of this announcement, confirm this trend and a presence of multiple zones of rich and in some cases, open ended mineralisation, means the Callancocha Structure Zone is now firmly set as a highly prospective drill target. Inca advised that results from a second program of trench channel sampling at Callancocha were expected around 4 January 2018. These results are now expected circa 22 January 2018. At or around the same time, Inca expects to report on channel sampling results of vein HV-21. Underground channel samples of veins HV-01 and HV-02 return strong zinc (Zn), silver (Ag), lead (Pb) grades. Vein HV-01 grades include: 7.78% Zn, 135.4g/t Ag, 8.36% Pb over 1.66m (true width) in channel 4 (samples IM-000492-496) including 15.45% Zn, 168.0g/t Ag, 11.61% Pb over 0.44m (sample IM-000492). 5.32% Zn, 106.1g/t Ag, 5.57% Pb over 1.23m (true width) in channel 3 (samples IM-000487-491) including 14.40% Zn, 231.0g/t Ag, 11.35% Pb over 0.30m (sample IM-000487). Vein HV-02 grades include: 8.43% Zn, 132.0g/t Ag, 14.96% Pb over 0.38m (true width) in channel 3 (sample IM-000477). 5.50% Zn, 88.2g/t Ag, 5.53% Pb over 0.31m in channel 1 (sample IM-000472). 2nd Callancocha trench channel sample program and HV-21 results available within 5-7 business days.
