Takeaway"The 421 zone mineralized system was generated from a buried multiphase porphyry copper-style intrusive to the north. A pervasive skarn alteration envelope surrounds the copper-gold mineralization, indicating that current drilling is on the correct trajectory to find the more proximal part of the system.There is significant, highly prospective exploration ground to the north with the opportunity to discover more of the high-grade copper-gold mineralization that we are seeing in the 421 zone. We also expect to see increased consistency in grades from hole to hole as we track the mineralizing fluids to their source. One of the most promising things about working toward the mineralization source is that we expect the sulphide replacement of the skarn alteration to be more complete closer to the high-energy heat source, theoretically resulting in even higher-grade material.
From the release - Stepout drilling along the projected strike and plunge of the 421 zone continues to show the lateral continuity of the 421 zone mineralized system, which the company believes was generated from a buried multiphase porphyry copper-style intrusive to the north. A pervasive skarn alteration envelope surrounds the copper-gold mineralization, indicating that current drilling is on the correct trajectory to find the more proximal part of the system.
The alteration encountered in 2019 drilling to date confirms our belief that we are still distant from the heart of the system, which indicates to us there is significant, highly prospective exploration ground to the north with the opportunity to discover more of the high-grade copper-gold mineralization that we are seeing in the 421 zone. We also expect to see increased consistency in grades from hole to hole as we track the mineralizing fluids to their source.
