Tier One Metals Identifies Large-Scale Chargeability and Magnetic Anomalies Under Extensive High-Grade Rock Samples from Surface

Vancouver, Canada – December 15, 2020 – Tier One Metals Inc. (“Tier One” or the “Company”) is pleased to provide 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 (Figure 1). 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 (Figure 2).

A Message from Ivan Bebek, Chair & Director:
“The sampling of extensive high-grade silver and gold on surface at Curibaya has been significant. We are thrilled to see the results from our geophysical studies, which indicate robust precious metal and porphyry targets beneath high-grade surface mineralization.

“In the coming weeks we look forward to the completion of the drill targeting, a significant corporate update, the obtaining of our FTA drill permit and the listing of Tier One Metals, anticipated in February.”

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 of the chargeability anomaly is defined by a 30-millivolt chargeability response with inner cores of 45 and 50 millivolts, respectively (Figure 2). 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 (Figure 2). 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 (Figures 3 & 4). The high-grade veins sampled demonstrate a strong spatial correlation to the chargeability anomaly and continue to strengthen the drill targeting currently underway. A summary of the results from this program is presented below in Table 1.

Drill Program & Permitting Process:
Tier One has submitted an application for a Ficha Tecnica Ambiental (FTA) (“Environmental Technical Report”) drill permit, which would enable the Company twenty drill pads. Approval of the FTA drill permit, as well as for all necessary community access agreements, is anticipated in January 2021. The Company is also filing for Inicio de Actividades (“Start of Activities”) permit with the goal of commencing drilling after the rainy season, near the end of Q1 of 2021.

A Message from Michael Henrichsen, Chief Geologist:
“The critical advancement of the geophysical surveys has provided the Tier One exploration team with a great deal of confidence as we advance our maiden drill program at the Curibaya project. The scale of the chargeability anomaly and the underlying magnetic anomaly demonstrate the potential to discover a significant precious metals system, in addition to a copper porphyry at depth, in this world-class metallogenic belt.”

Figure 1: Illustrates the position of the magnetic and chargeability anomalies that are spatially associated with silica and silica clay alteration styles. The chargeability anomaly is 2 km by 750 m at 30 millivolts and is interpreted to represent sulphide mineralization. The magnetic anomaly is situated beneath the chargeability anomaly and is interpreted as a causative intrusion to the precious metal veins sampled on surface. Tier One believes the magnetic anomaly may also represent a potential porphyry target beneath the mapped precious metals system.

Figure 2: Illustrates the position of the chargeability anomaly, the associated magnetic anomaly beneath the alteration system and high-grade precious metal samples. Collectively, the chargeability and magnetic anomalies represent a large-scale precious metal and copper porphyry target.

Figure 3: Illustrates silver results from the latest rock sampling program at the Curibaya project. The bulk of these samples are situated above the newly defined chargeability anomaly.

PERU Rocks Q4 2020 (Curibaya)

Approximately 2-3kg of material was collected for analysis and sent to ALS Lab in Arequipa, Peru for preparation and then to Lima, Peru for analysis. All samples are assayed using 30g nominal weight fire assay with ICP finish (Au-ICP21) and multi-element four acid digest ICP-AES/ICP-MS method (ME-MS61). Where ICP21 results were > 3 g/t Au the assay were repeated with 30g nominal weight fire assay with gravimetric finish (Au-GRA21). Where MS61 results were greater or near 10,000 ppm Cu, 10,000ppm Pb or 100ppm Ag the assay were repeated with ore grade four acid digest method (Cu,Pb,Ag-OG62). Where OG62 results were greater or near 1500ppm Ag the assay were repeated with 30g nominal weight fire assay with gravimetric finish (Ag-GRA21). Where Ag-GRA21 results were greater or near 10,000ppm Ag the assay were repeated with fire assay with gravimetric finish for concentrate (Ag-CON01). QA/QC programs for 2019/2020 rock samples using company and lab duplicates, standards and blanks indicate good accuracy and precision in a large majority of standards assayed.
