Subiaco WA / December 4, 2017 / JMN Wire / Auroch Minerals Ltd (ASX: AOU) Assay results for the first two holes (TIDD002 &TIDD003) at Tisová of the 4-hole drilling program have been received. The Cu Co assay results have not replicated the results obtained from grab samples reported from historic waste dumps on site.
With the onset of the northern winter, exploration activity has now been suspended in the Czech Republic and can only resume post snow melts in 2018.
CEO Dr Andrew Tunks said. “The assay results to date are disappointing and not in line with our expectations. Thick zones logged as disseminated sulphides have returned lower than expected values for the target metals and where grades are reasonable, thicknesses are narrow and below minimum mining widths. We await the results of the second two holes before formulating our future exploration plans.
Clearly the material we have drilled is substantially different from the samples we collected from the Tisová waste dumps. This points to a strong metal zonation within the Tisová orebody. We will review the 3D model of the sulphides and look to investigate geophysical methods to identify further sulphide bodies as a possible source of Co mineralisation in the dumps.
