Exploration expands mineralized gold zone at Luminaria, Peru VANCOUVER, Jan. 10 /PRNewswire-FirstCall/ -- Tinka Resources Limited (TSXv - TK; Frankfurt - TLD; Pinksheets - TKRFF). Mr. Andrew Carter, President, is pleased to report additional sampling results from the Company's 3,500 hectare Luminaria Project located in the Huaraz mining district, department of Ancash, Peru. A total of 269 soil samples were collected on a grid measuring roughly 1,800 metres by 300 metres. Anomalous gold values ranging from 0.02 g/t to 1.86 g/t are associated with anomalous copper, lead and arsenic values within an area 1,400 meters by 300 metres. The geochemically anomalous area is still open to the east and partially open to the west; geological mapping and soil sampling suggest that the mineralized area is faulted-off along the western edge of the grid. The Company will continue the grid soil sampling program to close off the geochemically anomalous area. Further channel sampling was done in four trenches (TK-15 to TK-18) which cut across the "manto" horizon immediately above fresh diorite near the eastern edge of the grid. The mineralized horizon in TK-16 and TK-17, located about 10 m apart along strike, yielded 12.8 g/t Au and 27.6 g/t Au, respectively, each over 0.7 m thickness. The anomalous gold values are associated mainly with pyrite, arsenopyrite and grey quartz occuring in the Chimu Formation, consisting of white quartzite with narrow shale and coal horizons in contact with strongly altered diorite. In the previous program, twenty-five pits were dug within the zone of interest to a maximum depth of 4 metres located within an area of about 270 metres by 100 metres. The pits intersected the Chimu formation and bottomed in strongly altered diorite intruding the overlying quartzites. Vertical channel samples in the pits ranged from 1.2 g/t gold to 24.6 g/t gold with an average of 7 g/t gold over 2 metres. Preliminary geological interpretations suggest that the mineralized horizon, or "manto" may be a stratabound feature within the Chimu formation occuring above a diorite sill, but this has not yet been confirmed. The mineralization is not confined to the sediments as highly anomalous gold values were obtained from altered diorite along a roadcut just east of a major fault separating the mineralized sequences to the east from barren diorite to the west. The diorite in the roadcut, from west to east, averaged 2.9 g/t Au over 6 m, 0.15 g/t Au over 12 m, 4.8 g/t Au over 12 m; 0.05 g/t Au over 10 m and ending in a 6 m section of quartzite that averaged 5.9 g/t Au. The analytical results and calculations were reviewed by John Nebocat, P.Eng., a "Qualified Person", who has not yet visited the Luminaria project area but will be examining it and conducting regional mapping in February, 2005. The Company is extremely encouraged by these early results and is planning to stream sediment sample the entire property in January, and to systematically excavate and sample additional pits along the extent of the known stratabound mineralization. These pits will be located systematically on the soil sampling grid.
