Tier One Silver Reports High-Grade Copper-Nickel Results from New Target at Hurricane Project in Peru

Rhea-AI Summary

Tier One Silver Inc. (TSLVF) has announced promising results from composite chip sampling at its Rayanpata target in the Hurricane project, southern Peru. Key findings include high-grade concentrations of copper (Cu), nickel (Ni), and cobalt (Co), with 65% of samples exceeding 0.1% Ni and two samples reporting Co values above 1,000 g/t. The area, measuring approximately 2 km by 800 metres, remains open for further exploration. Both Senior VP Exploration Christian Rios and CEO Peter Dembicki expressed optimism, highlighting the project's potential to identify extensions and new mineralized structures.

Positive

• High-grade sampling results include 1.59% Cu, 2.26% Ni, and 1,280 g/t Co.
• 65% of samples exceeded 0.1% Ni, indicating strong mineralization potential.
• The Rayanpata target is noted as the first copper-nickel magmatic sulphide system in Peru.

Negative

• None.

VANCOUVER, BC / ACCESSWIRE / February 16, 2023 / Tier One Silver Inc. (TSXV:TSLV)(OTCQB:TSLVF) ("Tier One" or the "Company") is pleased to report composite chip sampling highlights (covering 1 square metre per sample) of 1.59% copper (Cu), 0.24% nickel (Ni), 0.22 g/t palladium (Pd), 0.13 g/t platinum (Pt), 204 g/t cobalt (Co), 0.21 g/t gold (Au); 1.43% Cu, 1.86% Ni, 0.16 g/t Pd, 0.18 g/t Pt, 1,110 g/t Co and 0.84% Cu, 2.26% Ni, 0.24 g/t Pd, 0.24 g/t Pt, 1,280 g/t Co from the new Rayanpata target area at the Hurricane project in southern Peru (Figure 1). These results are part of a new area that is located 3 kilometres (km) north from the Magdalena high-grade silver vein target. The majority of the samples report high-grade values for copper, nickel and cobalt, and all of the results appear to be related to magmatic-style sulphide mineralization within a gabrodioritic sill. Of the 17 samples from Rayanpata, 65% report values above 0.1% Ni, 35% report values above 0.1% Cu and two samples report values above 1,000 g/t Co. Table 1 summarizes the highlights from the composite chip sampling program.

A Message from Christian Rios, SVP, Exploration:

"Hurricane's new Rayanpata target, and the San Cipriano and Ñañohuayco targets, are part of the first copper-nickel magmatic sulphide system that we know of in Peru. The Rayanpata target was found after only five days of field work, with occurrences identified over an area that is approximately 2 km by 800 metres in size. The system remains open in all directions and additional field work will focus on the identification of extensions to known mineralization, as well as additional mineralized structures. We are looking forward to advancing this new, high-grade target."

A Message from Peter Dembicki, CEO:

"Our Hurricane project continues to provide high-grade results, not only from existing targeted areas, but additional areas that have been of interest to our technical team since we optioned the project. We certainly believe that these copper and nickel grades are worth pursuing as we continue to define our Hurricane exploration programs for this year."

Rayanpata Cu-Ni Structures:

Sulphide mineralization occurs in gabrodioritic sills and breccias with high values ​​of nickel, cobalt and copper. Reconnaissance sampling work, including sampling of outcropping mafic intrusives, provided an initial assessment of grade potential and distribution (Figures 1 - 2 and Table 1).

Two styles of mineralization have been recognized to date: crackle breccia type mineralization and gabrodioritic sills in the hanging wall to the breccias, with disseminated chalcopyrite, pentlandite, and copper oxides. These structures were recognized and sampled in the Rayanpata creek as nearly 85% of the target area is obscured by shallow erosional cover and vegetation. The area is open in all directions and Tier One's technical team believes there is significant potential to discover extensions and additional mineralized structures. The only sample that was not taken from outcropping mineralization reported values of 1.33% Cu, 0.80% Ni and 540 g/t Co, indicating the potential for buried intrusives in the area.

The next phase of exploration at the Rayanpata target will include detailed mapping to identify similar structures or a possible magmatic source to the observed mineralization, as well as rock, channel and soil sampling.

Composite Chip Sampling:

Approximately 2-3 kg of rock material was collected over 1 square metre for analysis and sent to ALS Lab in Arequipa, Peru for preparation and then to Lima, Peru for analysis. All samples are assayed for gold, platinum and palladium using 30 g nominal weight fire assay with ICP-AES finish method (PGM-ICP23) and for multi-element using four acid digest ICP-AES/ICP-MS method (ME-MS61). Where MS61 results were greater or near 10,000 ppm Cu, 10,000 ppm Pb, 10,000 ppm Zn or 100 ppm Ag, the assays were repeated with ore grade four acid digest method (Cu, Pb, Zn, Ag-OG62). Where OG62 results were greater or near 1,500 ppm Ag, the assays were repeated with 30 g nominal weight fire assay with gravimetric finish (Ag-GRA21). QA/QC programs for 2022 rock samples at Hurricane using internal and lab standard and blank samples, and lab duplicates, indicate good overall accuracy and precision.
