Cordoba Minerals Reports Assay Results from K-20 Drill Hole at Perseverance Porphyry Copper Project in Arizona, USA

May 21, 2019

HPX majority-owned subsidiary Cordoba Minerals Corp. (TSX-V:CDB; OTCQB:CDBMF) is pleased to announce assay results from diamond drill hole K-20 completed at the Perseverance porphyry copper project in northwestern Arizona, USA.


  • Assay results from drill hole K-20, drilled vertically to a depth of 1,319 metres, returned anomalous copper values averaging 415 ppm copper over 595 metres (using a 200 ppm copper cut-off grade), beginning at a depth of 683 metres. This long intercept of anomalous copper indicates that the hole intersected the peripheral part of a porphyry copper system.
  • Magneto-telluric (“MT”) data, collected by a previous Bell Copper Corporation joint venture partner, suggest that the centre of the porphyry copper system is located to the northeast of drill hole K-20, as also verified by downhole acoustic televiewer (“ATV”) measurements of fractures and vein-sets.
  • The next step in the exploration program will be to extend MT coverage to the northeast to close-off the existing deep conductive anomaly prior to further drilling. Diamond drilling is expected to recommence shortly thereafter.
