Tier One Metals Inc. provided an update on its targeting efforts at the Curibaya precious metals project in southern Peru. In an effort to identify the potential source of the numerous high-grade silver and gold veins sampled on surface, the Company completed a 450-line kilometre (km) airborne magnetic survey and a 30-line km ground-based induced polarization survey over the 20 square km alteration zone. These surveys identified a 2 km by 750 metre (m) chargeability anomaly near surface, which represents a precious metals target, and a magnetic anomaly located spatially below the chargeability anomaly. Tier One's technical team is interpreting the magnetic anomaly to be the causative intrusion responsible for driving the high-grade silver and gold mineralization sampled on surface and believes it may also represent a potential porphyry target beneath the mapped precious metals system). Geophysical Advancement & Targeting: The chargeability anomaly identified in the induced polarization survey is situated beneath and parallel to the most intense silica and silica clay alteration zones on the project, as well as the two high-grade silver - gold Sambalay vein corridors. The outer shell of the chargeability anomaly is defined by a 30-millivolt chargeability response with inner cores of 45 and 50 millivolts, respectively. These values are consistent with sulphide mineralization and demonstrate the potential to find a large-scale precious metal system at shallow depth on the project. The magnetic anomaly that has been defined from the airborne survey is situated beneath the large- scale chargeability anomaly. Tier One's technical team is interpreting this anomaly as the causative intrusion driving the precious metal mineralization sampled on surface and believes that it may represent a potential porphyry target beneath the mapped precious metals system. The results of the geophysical surveys are currently being integrated with geological mapping and alteration data in order to define a drill plan, which is anticipated in January of 2021. Additional Vein Sampling Continues to Return High-Grade: Tier One recently completed a rock sampling program within the defined vein corridors that are situated above the geophysical anomalies to assist in drill targeting. Results included up to 934 g/t gold and +10,000 g/t silver in selective grab samples. The high-grade veins sampled demonstrate a strong spatial correlation to the chargeability anomaly and continue to strengthen the drill targeting currently underway.
