Cordoba Minerals (TSXV:CDB,OTCQB:CDBMF) has released assay results from diamond drill hole K-20 at the Perseverance porphyry copper project in Arizona.
Highlights from the press release are as follows:
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 measurements of fractures and vein-sets.
The next step in the Company’s 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.
Eric Finlayson, Cordoba President and CEO, commented:
“Our understanding of the Perseverance porphyry copper system continues to improve. Evidence suggests that K-20 is located on the southwestern margin of a concealed Laramide porphyry copper system. We believe that there is good potential for a significant copper discovery and are very pleased to have completed the necessary spending requirements to increase our project ownership to 25 percent.”
