Tier One Silver Commences CSAMT at Curibaya to Refine Copper Porphyry Targets
Tier One Silver Commences CSAMT at Curibaya to Refine Copper Porphyry
Targets
Vancouver, Canada – September 12, 2022 – Tier One Silver Inc. (TSXV: TSLV, OTCQB: TSLVF)
(“Tier One” or the “Company”) is pleased to announce that it has initiated a 35-line kilometre (km)
Controlled-Source-Audio-Frequency Magnetotelluric (CSAMT) geophysical survey in the central
portion of the Curibaya project in southern Peru. The purpose of this survey is to define t he
resistivity properties at depth, where zones of lower resistivity and higher conductivity can indicate
zones of intense hydrothermal alteration that may be associated with a copper porphyry system at
depth (Figure 1). Upon completion of the survey and final targeting the Company plans to drill test
for a potential porphyry system underlying the e pithermal system defined on surface. Currently,
results are pending from a channel sampling program to refine precious metals targets within the
newly permitted Cambaya target area.
A Message from Peter Dembicki, President, CEO and Director:
”The CSAMT geophysical survey is a key component to learning more about potential copper
porphyry mineralization, which we saw indications for in our first phase of exploration at Curibaya.
This is an exciting development for the Company to ward unlocking the large opportunity of a
potential copper porphyry deposit alongside the epithermal silver system that we’ve already
identified, and we look forward to defining these targets for our next drill program.”
Copper Porphyry Potential:
The first phase of drilling and surface work has provided several lines of evidence that a porphyry
target exists in the central region of the mineralized system, as it is currently defined. An analysis
of vein geochemistry across the property has demonstrated concentric zonation with copper-lead-
zinc zoning outward into lead +/ - copper and then zinc +/ - lead in the peripheral zone (Figure 1).
This geochemical zonation is consistent with porphyry systems and the central copper -lead-zinc
zone would be the primary target area at depth. Within the copper – lead – zinc geochemical core,
skarn mineralization is observed on surface, indicating a proximity to intrusives. Small scale 1 – 2
metre (m) wide porphyry dykes and associated magnetite veinlets were intersec ted in the phase I
drill program within the Madre and Tipal structural corridors, also indicating the potential for a
proximal porphyry. In addition, drill holes 6 and 8 had intercepts of molybdenum (Mo) grading 5 m
of 85 ppm Mo and 44 m of 52 ppm Mo, resp ectively, providing a potential vector to a porphyry
system at depth (Figure 2). Collectively, these lines of evidence support further targeting work and
vectoring toward a porphyry system at depth.
Figure 1: Illustrates the geochemical zonation observed within the precious metal veins within the Curibaya project area. An
analysis of vein geochemistry across the property has demonstrated concentric zonation with copper -lead-zinc zoning
outward into lead +/ - copper and then zinc +/ - lead in the peripheral zone. This geochemical zonation is consistent with
porphyry systems and the central copper-lead-zinc zone would be the primary target area at depth. In addition, the magnetic
and chargeability anomalies shown on the figure could represent an intrusion or potassic alteration and sulphidation,
respectively, at a depth of approximately 400 m.
Figure 2: Illustrates the conceptual geological model for mineralization at the Curibaya project. Importantly, higher
elevations are interpreted to represent an increase in the vertical extent of the precious metal mineralization with a
porphyry target at depth, between the Sama and Sambalay corridors, as evidenced by: geochemical zonation within the
vein geochemistry, skarn mineralization observed at low elevations in the vicinity of the Madre corridor, molybdenum
increasing with depth in drill holes 6 and 8, as well as the presence of magnetic anomalies at a depth of approximately
400 m.

Curibaya Drilling
Analytical samples were taken by sawing HQ or NQ diameter core into equal halves on site and sent one of the halves to
ALS Lab in Arequipa, Peru for preparation and then to Lima, Peru for analysis. All samples are assayed using 30 g nominal
weight fire assay with atomic absorption finish (Au-AA25) and multi-element 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 or 100 ppm Ag the assay were repeated
with ore grade four acid digest method (Cu, Pb, Ag-OG62). Where OG62 results were greater or near 1,500 ppm Ag the
assay were repeated with 30 g nominal weight fire assay with gravimetric finish (Ag-GRA21).
QA/QC programs for 2021 core samples using company and lab duplicates, standards and blanks indicate good accuracy
and precision in a large majority of standards assayed.
True widths of mineralization are unknown based on current geometric understanding of the mineralized intervals.
Channel Sampling – Curibaya
Analytical samples were taken from each 1-metre interval of channel floor resulting in approximately 2-3 kg of rock chips
material per sample. Collected samples were sent to ALS Lab in Arequipa, Peru for preparation and then to Lima, Peru
for analysis. All samples are assayed using 3 0 g nominal weight fire assay with atomic absorption finish (Au -AA25) and
multi-element four acid digest ICP-AES/ICP-MS method (ME-MS61). Where MS61 results were greater or near 10000 ppm
Cu, 10000 ppm Pb or 100 ppm Ag the assay were repeated with ore grad e four acid digest method (Cu, Pb, Ag -OG62).
Where OG62 results were greater or near 1500 ppm Ag the assay were repeated with 30 g nominal weight fire assay with
gravimetric finish (Ag -GRA21). QA/QC programs for 2021 channel samples using internal standard and blank samples;
field and lab duplicates indicate good overall accuracy and precision.
