High-Grade Porphyry Identified at Cuba Zone generates another new drill target at the Miner Mountain Project, British Columbia
Vancouver, British Columbia, November 28, 2019 – Sego Resources Inc. is pleased to announce another drill target has been identified at Miner Mountain. A re-evaluation of drill core from the Cuba Zone identifies a high-grade porphyry with local zones of 1-2 percent (%) copper and 0.5 grams per tonne (g/t) gold that has been pervasively overprinted by later grade- destructive alteration. The porphyry is open beneath the level of current drilling and the destructive alteration is expected to be restricted to shallower levels based on similar alteration at alkalic porphyry deposits including New Afton (Tolman and Lipske, 2016) and Cadia East (Wilson, 2003).
This target was generated during a review of the property and its potential, undertaken by the company in conjunction with consultant Dr Alan Wilson, an expert in alkalic porphyry deposits who completed his PhD on the Cadia deposit in Australia and was recently the International Exploration Manager for Antofagasta Minerals.
“Recognising the high-grade porphyry at the Cuba Zone and understanding the reason for the loss of copper and gold mineralisation is a significant breakthrough. Testing deeper beneath this overprint is a compelling target and proceeding to a drill program in the first months of 2020 is a priority for the company,” commented Sego CEO J. Paul Stevenson. “Adding a high-grade target at the Cuba Zone to the Empress, South Zone Gold-Copper and Sovereign geochemical and geophysical targets announced in mid-October only adds to the discovery potential at Miner Mountain.”
Previously reported grades that show the tenor of the mineralization include:
DDH 12-21: 100 metres grading 0.95% copper and 0.55 g/t gold
DDH 12-26: 12.2 metres grading 1.16% copper and 0.76 g/t gold
PDH 11-94 82 metres grading 1.01% copper and 0.58 g/t gold
Intervals that retain some mineralization as windows within partially to pervasively overprinted include:
DDH 17-30: 105 metres grading 0.31% copper and 0.08 g/t gold
DDH 18-34: 18 metres grading 0.56% copper and 0.06g/t gold
