Tinka Resources Limited, announces that further exploration has commenced on the Chaucha zone located about 1.2 km northeast of the Colquipucro silver resource.
Exploration conducted in 2008 had identified an extensive zone of iron and manganese rich gossanous outcrops hosted by the Pucará limestone. The gossans occur as both chimneys and mantos. A follow-up program, focused on the structural interpretation of the property, determined that Chaucha occurs on the northeastern limb of a broad fold (anticline), and that it appears to be the extension of similar style mineralization observed at, and immediately below, the Clinker zone which occurs at the north end of the Colquipucro deposit.
The following table is a summary of the significant surface rock sample results obtained and reported at that time (see news release October 21, 2008). Sampling was restricted to an area roughly 150 m by 150 m, but this is not the limit to the prospective area. A large northwest-southeast trending fault truncates the Chaucha showing. Abundant gypsum and anhydrite alteration occurs along the fault trace over a strike length in excess of 1 km. The footwall of this fault (NE-side) appears to be entirely within the Pucará limestones, but much of it is hidden by the gypsum veining/alteration.
In addition, a soil sampling survey conducted in 2008, extending from Colquipucro northwards to the Chaucha zone, yielded wide areas of anomalous zinc, lead and silver. These anomalous areas will also be explored in detail.
The Company's focus during 2007/2008 was exploring the sandstone-hosted silver resource at Colquipucro; thus Chaucha, and other showings on the property, received little attention. Since the discovery of unoxidised massive and semi-massive sulphides (zinc, lead) at depth along the Ayawilca zone, the Company has decided to re-evaluate and further explore Chaucha and other potentially significant base metal targets on the property.
The Company's Qualified Person, John Nebocat (P.Eng.), has reviewed and approved the contents of this news release.
