Tier One Silver Resumes Exploration Activities on Highly Prospective Cambaya Corridor at Curibaya

In This Article:

VANCOUVER, BC / ACCESSWIRE / July 15, 2024 / Tier One Silver Inc. (TSXV:TSLV)(OTCQB:TSLVF) ("Tier One" or the "Company") is pleased to announce that it has resumed exploration activities at its flagship Curibaya project, located in Southern Peru. The exploration program has been planned to cover three main project zones within the Company's high-priority silver-gold corridors that have been underexplored to date: Cambaya I, Cambaya II and the recently identified polymictic breccia in Zone 1 (Figure 1). The program will consist of two to three months of field work, including sampling and geological mapping, with the aim of expanding and defining the potential of the precious metal epithermal corridors and the porphyry target based on existing geochemical and CSAMT geophysical anomalies, to delineate drill targets for the drill program anticipated for later this year.

Peter Dembicki, CEO and Director of Tier One commented, "We are excited to be resuming exploration at our highly underexplored Curibaya property. We have only explored a small fraction of the project and identified six distinct silver-gold mineralized kilometric corridors to date. Our focus for this program, and upcoming drilling, is the Cambaya corridors, which are higher in elevation where there is potential for high grade silver mineralization and scale. We are still very early in our exploration efforts of pursuing a world class discovery in Peru. Evidence gathered to date from surface mineralization and drill holes has strengthened our thesis that both a high-grade precious metals system as well as a porphyry copper system could exist on the large prospective property."

Cambaya I and Cambaya II Corridors:

The Cambaya structural corridors are located in the northeast area of the project (Figure 1), which is the highest target in topographic elevation (2400m above sea level) and within the epithermal system with highly elevated arsenic values, indicating that the potential precious metals horizon is being preserved at shallow depth (see news release date September 26, 2022).

Highlights from previous channel sampling (refer to press releases dated October 14, 2021 and September 26, 2022) in these corridors include:

? 4.5 metres (m) of 408.2 g/t silver (Ag) and 1.48 g/t gold (Au), including 1 m of 1,768.0 g/t Ag and 6.33 g/t Au, in 22CRT-080;
? 8 m of 349.1 g/t Ag and 0.46 g/t Au, including 1 m of 2,680.0 g/t Ag and 3.14 g/t Au, in 21CRT-56;
? 2.5 m of 136.4 g/t Ag and 0.82 g/t Au, including 0.5 m of 568.0 g/t Ag and 3.37 g/t Au, in 22CRT-101;
? 20 m of 242.7 g/t Ag and 0.71 g/t Au in 21CRT-55;
? 2 m of 1,074 g/t Ag and 0.53 g/t Au in 21CRT-44;
? 11 m of 232.1 g/t Ag and 1.6 g/t Au, including 1 m of 1660 g/t Ag and 14 g/t Au, in 21CRT-34;
? 9 m of 409 g/t Ag and 0.4 g/t Au including 3 m of 949.7 g/t Ag and 0.8 g/t Au in 21CRT-36;
? 2 m of 1736.5 g/t Ag and 1.6 g/t Au including 1 m of 3170 g/t Ag and 2 g/t Au in 21CRT-52.

The intention for this fieldwork campaign is to extend both corridors and gain a better understanding of the geometry of the ore shoots within each corridor.
