Vancouver, British Columbia – October 19, 2021 (Newsfile Corp.) (Investorideas.com Newswire) Sarah Armstrong-Montoya, President and Chief Executive Officer of Cordoba Minerals Corp. (TSXV: CDB) (OTCQB: CDBMF; otherwise “Cordoba” or the “Company”) is pleased to announce that drilling has commenced today at the Perseverance porphyry copper project, located in northwestern Arizona, USA.
- Assay results from drill hole K-20, drilled in early 2018 to a vertical 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 Cordoba’s news release dated May 21, 2019). This long intercept of anomalous copper could indicate that the hole intersected the low grade, peripheral envelope to a porphyry copper system.
- Magneto-telluric (“MT”) data collected to date have defined two low resistivity anomalies of less than 10 ohm-m located to the north and to the east of drill hole K-20. A low resistivity anomaly of less than 14 ohm-m is a characteristic feature of the giant, high-grade Resolution porphyry copper deposit in Arizona owned by Rio Tinto and BHP.
- An initial two diamond drill hole program has commenced today to test the Northern MT anomaly.
“We are excited to recommence drilling at Perseverance, and follow-up on K-20 which returned more copper than any previous holes on the project. Our geologists have identified two highly prospective targets based on the partial data received from the recent MT survey,” commented Ms. Armstrong-Montoya. “We believe there is great potential at Perseverance.”
K-20 Suggested Proximity to Porphyry Copper System
Cordoba previously announced that diamond drill hole K-20 was halted at a depth of 1,319 metres (refer to Cordoba’s news release dated February 25, 2019). 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 Cordoba’s news release dated May 21, 2019). This long intercept of anomalous copper could indicate that the hole intersected the peripheral, weakly mineralized zone of a porphyry copper system.
MT Survey Suspended Due To COVID-19; Partial Data Now Analyzed
Cordoba contracted Quantec Geoscience to conduct a Spartan MT survey over the Perseverance project area to extend the previous Quantec Titan MT survey conducted in 2017 by the previous project operator. The Titan survey indicated a deep geophysical (50 ohm-m) conductor trending NE towards the K-20 drill hole (refer to Cordoba’s news release dated May 21, 2019). With the combination of the deep trending MT anomaly and the long interval of anomalous copper intercepted by K-20, Cordoba believed a porphyry centre could lie to the NE of K-20.
Cordoba was forced to suspend the Spartan MT survey due to the COVID-19 pandemic, and the full extent of the planned survey was never completed. However, Cordoba has been able to interpret the data received from the partially-completed survey, and has now defined two low resistivity anomalies of less than 10 ohm-m – comparable to the giant, high-grade Resolution porphyry copper deposit near Superior, Arizona (Figure 3).
The larger of the two anomalies, designated the Northern MT feature, is centred 1.5 km to the north of K-20, while the slightly smaller Eastern MT anomaly is centred 2.3 km east of K-20 (Figures 1 & 6). The anomalies both initiate at the basement contact with the valley fill approximately 300 metres below surface and extend over 1 km vertically down in bedrock (Figures 2 & 6). A horizontal MT conductor also lies along the bedrock surface at the base of the valley fill and could represent groundwater pooled at the top of the bedrock surface. The Company believes the cause of the vertical, bedrock MT anomaly may be conductive porphyry-style alteration and mineralization similar to the MT anomaly that caps the Resolution deposit (Figure 3).
Diamond drilling has commenced with an initial 2-hole program to test the Northern MT anomaly. The first hole K-21 (Figures 1, 2 & 4) is centred on the 2 km long Northern MT anomaly with the second hole, pDDH21-02, targeting a 400 metre step to the north; as shown in Figures 1, 2 & 5. With positive results, a total of 6 additional holes are planned in the future for the Northern anomaly on approximately 400 metres centres to delineate the extent of the MT feature. Drilling on MT Eastern anomaly will be predicated on the success of the Northern program.
Perseverance Option Agreement
In 2019, Cordoba completed the Phase 1 earn-in requirement of the Perseverance Joint Venture agreement and vested a 25% interest in the property. Cordoba is working to complete its Phase 2 earn-in to vest a 51% interest.
