Examples

  • As a substantial, higher grade chalcocite-covellite zone near surface appears to be amenable to heap leaching, the 2010 drilling program will provide information to complete an independent, NI 43-101 compliant, Preliminary Economic Assessment ( "PEA") on a Solvent Extraction-Electrowinning ( "SX/EW") copper heap leaching operation within the next ten months, with a Preliminary Feasibility Study to follow, if warranted.

  • The copper mineralization within the upper 300 metres of the deposit includes both supergene digenite-covellite and hypogene chalcocite-bornite replacing earlier chalcopyrite.

    Marketwire - Breaking News Releases

  • The deposit hosts a large zone of near-surface, higher-grade chalcocite-covellite copper mineralization that we believe will be amenable to SX/EW, heap leach copper production.

    Marketwire - Breaking News Releases

  • Mixed copper mineralization may contain both chalcocite-covellite and chalcopyrite-bornite mineralization.

  • ALD-132 Mixed Cu mineralization 0.1 including Chalcocite-covellite zone 0.2

    The Earth Times Online Newspaper

  • In this fifth and final set of results from 19 of 76 holes drilled this year, long intervals of copper mineralization were intersected in the chalcocite-covellite dominant zone

    The Earth Times Online Newspaper

  • Of particular note were intersections from the potentially leachable chalcocite-covellite dominant mineralization in hole ALD-136 of 0.568% Cu over 178 metres including 78 metres of 0.692% Cu and in hole ALD-138 of 0.791% Cu over 60 metres.

  • ALD-103 Mixed Cu mineralization 0.1 including Chalcocite-covellite zone 0.2

    The Earth Times Online Newspaper

  • The two major goals of the 2010 drilling programme at Altar are to further define the higher-grade, chalcocite-covellite zone which appears to be amendable to heap leaching, and to expand the global copper resource.

  • ALD-139 Mixed Cu mineralization 0.2 including Chalcocite-covellite zone 0.4
