Copper Levels Provide Evidence of Nearby Laramide Porphyry Copper System; Cordoba Completes Phase 1 Earn-In, Increasing Cordoba's Ownership Interest in the Perseverance Project to 25%
Vancouver, British Columbia--(Newsfile Corp. - May 21, 2019) - Cordoba Minerals Corp. (TSXV: CDB) (OTCQB: CDBMF) ("Cordoba" or the "Company") 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 (refer to Table 1). 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 ("Bell Copper") 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 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.
"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," stated Eric Finlayson, President and CEO of Cordoba. "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%."
K-20 Appears to be Located on the Periphery of a Porphyry System
Cordoba previously announced that diamond drill hole K-20 was halted at a depth of approximately 1,045 metres pending further geological review (refer to Cordoba's news release dated January 21, 2019). After detailed discussions between geologists at Cordoba, Bell Copper and High Power Exploration Inc. ("HPX"), the Company decided to extend K-20 to a final depth of 1,319 metres (refer to Cordoba's news release dated February 25, 2019).
K-20 is believed to be located on the periphery of a porphyry copper system, as indicated by a deep resistivity low located by a previous MT survey (see Figures 1 and 2). However, this survey, completed in 2017, did not close-off this anomaly and did not extend as far to the northeast as the K-20 drill hole. Similar, large low resistivity anomalies are associated with major porphyry copper systems elsewhere.
The fact that all three drill holes with anomalous copper values (K11, K12A and K-20) show these values mid-way down hole suggests that the holes intersected either the distal edge of a copper shell or conduits that channelled hydrothermal fluid away from the porphyry.

Perseverance Option Agreement
On May 6, 2019, Cordoba provided formal notification to Bell Copper that the Company's total spending on the Perseverance Project has exceeded the C$1.0 million Phase 1 threshold (refer to Cordoba's August 27, 2018 news release) and that the Company has therefore vested a 25% interest in the property.
