Investors had to wait longer than expected for a big hit, but this week Tinka Resources (TK.V, TKRFF.US) proved that looking for substantially more mineralization first instead of preparing a Preliminary Economic Assessment (PEA) is a viable strategy. The latest hole returned an amazing intercept of 10.4m grading 44.0% Zn at West Ayawilca, and what is particularly interesting is that management seems to be verifying their new theory on Ayawilca structural controls of geology with this result.
