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

Vancouver, Canada – 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 potentialGrearprecious 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.

Zone 1:

The Company will also be following up on the strong stream sediment copper signatures in Zone 1, which is located on the west side of the primary Cambaya I and Cambaya II corridors, where minimum exploration has occurred to date (Figure 2).

Besides having high bulk leach extractable gold (“BLEG”) anomalies in copper and gold, this area returned high grade silver samples up to 1,360 g/t Ag, 42.20 Au and 6.12% Cu related to silicified fragments in a possible polymictic shatter breccia.

Field work in this campaign will be focused on extending the north-south extension of this polymictic breccia and to help better understand its geometry.

The current exploration work will help to further delineate drill targets within the area that has greater widths and higher grades (Figure 3), for a follow up drill program planned, subject to financing, to test the targets identified within the Cambaya corridors.

Tier One Silver Defines Porphyry Copper Targets at Curibaya
January 30, 2023
Vancouver, Canada – January 30, 2022 – Tier One Silver Inc. (TSXV: TSLV, OTCQB: TSLVF) (“Tier One” or the “Company”) is pleased to announce that recent geophysical survey results, combined with existing exploration data sets, have led to the identification of two porphyry copper targets underlying the silver-gold epithermal mineralization defined on surface at its Curibaya project in southern Peru. Tier One Silver completed a 42.7-line kilometre (km) Controlled-Source-Audio-Frequency Magnetotelluric (CSAMT) geophysical survey over the central portion of the Curibaya project in late 2022 (Figure 1). These new data sets were integrated into the exploration model, building on previous geophysical, geochemical and geological data sets, to generate targets for the Company’s next drill program at the project. The drilling, which is anticipated to begin in Q2, will comprise of approximately 5,000 metres (m) to follow-up on the high-grade silver-gold epithermal mineralization defined at surface and target the two main conductive features that may relate to a porphyry system.

Highlights:

CSAMT identifies two sub-vertical, low resistivity anomalies (400 m x 400 m and 600 m x 500 m) that are interpreted to be associated with a large-scale hydrothermal alteration system
Anomalies correlate with areas of multiphase alteration systems, including:
Advanced argillic alteration
Skarn and hornfels
Sericite – phengite – muscovite
Anomalies correlate with elevated bismuth, tellurium, selenium and copper values in rock samples
Absolute dating of alteration mineral in anomalies yielded a Paleocene age of 55Ma, which is a similar age to the regional porphyry copper giant deposits, Toquepala (57Ma), Cuajone (52Ma) and Quellaveco (55 Ma)
A Message from Christian Rios, SVP, Exploration:

“We believe the targets we’ve identified could be associated with a porphyry copper system at depth, particularly considering the absolute dating results, which indicate the mineralization to be from the Paleocene era. This provides further evidence that we are in the correct regional environment as the similar Paleocene-aged giant porphyry copper deposits nearby. We look forward to testing these strong targets in our next drill campaign.”

CSAMT Results:

A CSAMT geophysical survey was completed in October 2022 to augment previously completed geophysical, geochemical and geological surveys. CSAMT is used as an exploration tool to identify deeply rooted resistive and conductive features that may correlate to feeder and breccia structures, and/or zones of silicification and clay alteration, possibly related to porphyry copper targets (Figure 2). An inversion of the Curibaya CSAMT data outlines two main conductive features that are 400 m by 400 m and 600 m by 500 m, respectively, and show significant depth extent over 700 m (Figure 3). Pseudo sections for lines L5800 and L6200 clearly illustrate sub-vertical conductive features (Figure 4).

Both the high conductivity and low resistivity features are sub-vertical and located under important alteration features such as an advanced argillic lithocap, a skarn and hornfels area and a white mica alteration area. Additionally, these conductive anomalies are geochemically anomalous in bismuth, tellurium, selenium and copper. The hydrothermal alteration present in the upper part of the system and the geophysical features are consistent with buried porphyry systems.

Strategy for H1 2023:

The synthesis and interpretation of these targets is ongoing and includes re-logging core and continued integration with other geophysical and geochemical datasets. The Company expects to have defined drill targets in the coming weeks. Upon completion of target definition, a drill program will be finalized to test for both the possible porphyry source (drilling to a depth of 500m - 800m) and the epithermal silver – gold structures (between 150m - 250m) on the property. The exploration field program is expected to start in Q2 2023.

Figure 2: Illustrates line L5800 and the zones of lower resistivity and higher conductivity, which may indicate zones of intense hydrothermal alteration that could be associated with a porphyry copper system. In addition, drill hole 8 is illustrated, which encountered 44 m of 52 ppm of molybdenum at a depth of approximately 270 m, which is another indication of a potential porphyry copper system.

The Company is also announcing that Michael Henrichsen is retiring as Chief Geologist of Tier One Silver to focus his efforts as Chief Geological Officer of Torq Resources. Tier One has been transitioning toward this restructuring since the appointment of Christian Rios as SVP of Exploration, who will be leading exploration operations at the Company going forward. Mr. Henrichsen will still be available to Tier One as a consultant, as needed.

CSAMT Parameters

The CSAMT survey was carried out by Quantec Geoscience Perú S.A.C., a company based in Vancouver with divisions operating in South America, including Peru. Data points were collected on grid lines-oriented NW-SE using 50 m station spacings, covering an area of approximately 4.5 km x 3.5 km. Overall, data quality is considered well above average and no stations were affected by external factors.

Results were compiled into sections, grid maps and a 3D Voxel model. Occam or Marquardt 1D Inversions are first used to invert the data to produce a smooth-layer 1-D resistivity/depth curve for each station. To avoid the effects of the near-field, some frequencies were removed.

Readings are statistically averaged based upon adjacent points to produce an associated value for each cell. Quantec Geoscience Perú S.A.C. provides high confidence in readings to a depth of at least 700 m.
