Oreterra Confirms Two Broad Zones of
Epithermal Gold Mineralization with Assays to
50.5 g/t Au Overlying Porphyry Targets at the
Kinkaid Project, Nevada
Toronto, Ontario--(Newsfile Corp. - March 17, 2026) -
Oreterra Metals Corp. (TSXV: OTMC) (OTCID:
OTMCF) (FSE: D4R0) (WKN: A421RQ)
("
Oreterra
" or the "
Company
") is pleased to report very
encouraging assay results from late 2025 field work (Table 1, below) on the Company's 100% owned,
road-accessible Kinkaid project in the Walker Lane trend of southwestern Nevada.
The work was in
follow-up to the initial discovery of epithermal style gold mineralization in spring 2025 at the PM Skarn
and Bismark Hill targets (
see news, August 7, 2025
). These zones, along with dozens of old mine
workings and prospect pits dispersed across the Kinkaid property, appear to be part of much larger
alteration and mineralization systems postulated to overlie as many as four buried porphyry Cu-Au
intrusive centres (see Figure 1). The goal of the ongoing programs of mapping, rock and soil sampling,
together with an upcoming aeromagnetic and radiometric survey, as well as an induced polarization (IP)
survey anticipated for later in 2026, is to advance the PM Skarn and Bismark Hill gold targets and the
various porphyry targets toward drill-ready status.
"The Kinkaid property bears watching for its potential to deliver, within the next two years, a cluster of
porphyry discoveries in one of the foremost mining jurisdictions in the world," said Kevin Keough, Chief
Executive Officer. "Kinkaid adds depth to our property portfolio, and we own 100% of it. In the meantime,
all eyes are on our large-scale Trek South porphyry copper-gold prospect in BC's Golden Triangle, only
recently exposed by glacial ice retreat, which could deliver a major discovery this summer."
Highlights of Recent Work - Bismark Hill Target
A Short-Wave Infrared (SWIR) alteration mineral study undertaken in 2023 identified a series of strong
sericite (white mica) anomalies coincident with known mineralization on the property as well as multiple
anomalies clustered in a 350 x 240 metre alteration zone centred on Bismark Hill (see Figure 2).
Sericite is a key indicator mineral for hydrothermal alteration commonly associated with copper and gold
bearing systems. The fall 2025 work, coupled with earlier sampling by the Company, has now confirmed
the presence of gold ± copper mineralization at every sericite anomaly around Bismark Hill (Fig. 2).
Noteworthy results include:
An exposed 20 metre wide, sericite-altered zone returned a grab sample assay of
50.5 g/t Au
from a red, hematite stained, 10 cm wide, quartz-veined alteration "pod", one of many such pods 5
to 20 cm in width scattered throughout the alteration zone. A sample of a similar pod taken in May
2025 assayed 13.95 g/t Au (
see news, August 7, 2025
);
Chip samples of the sericitic zone containing approximately 50% of these red pods assayed
23.68
g/t Au across 0.6 metres
and
5.55 g/t Au across 1.52 metres
;
Numerous large quartz veins, 20 to 60 cm in width, containing copper and gold mineralization have
now been found up to 100 metres northeast and 200 metres east-northeast of the sericite zone
mentioned above. Grab samples of these veins assayed from
0.17 to 0.50 g/t Au
and
0.2% to
0.55% Cu
.
Similar but higher-grade veins were found in previous prospecting programs to the
south and southeast of the sericite zone.
These returned grab sample assays up to
36 g/t Au
and
4.8% Cu
(see Fig. 2 and
news, March 10, 2022
);
A weakly altered felsic volcanic rock cut by a series of thin quartz ± barite veinlets assayed
0.28 g/t
Au across 9.45 metres
with relatively consistent gold values throughout and locally elevated
antimony and copper values up to 25 ppm Sb and 442 ppm Cu. This zone illustrates how non-
descript some previously unrecognized mineralized areas on the property can be.
*Readers should note that grab samples are by their nature selective, and despite our best efforts
may not always be representative of the true style and overall grade of mineralization, nor represent
true widths of mineralization.
"The geology of the mineralization and the related alteration as well as the trace element content of
the mineralization (e.g., up to 21,798 ppb mercury and 786 ppm antimony) are indicative of an
epithermal mineralizing system, likely emanating from an intrusive, porphyry type centre at depth,"
stated John Biczok, P. Geo., Oreterra's Vice President Exploration. "
The Company plans to carry out
detailed chip sampling of these two recently discovered epithermal zones this spring, along with
further soil sampling and mapping of other sericite anomalies and related prospects on the claims, in
addition to a property-wide airborne magnetic and radiometric survey. The airborne surveys are
expected to help delineate the presumed underlying porphyry centres and outline the sericitic
alteration associated with the mineralization, after which induced polarization surveys will be carried
out to identify targets for follow-up drilling."

Highlights of Recent Work - PM Skarn Zone
A 30 metre wide zone of intermittently exposed, gold-bearing, chalcedonic quartz flooding was first
located adjacent to the PM Skarn zone on the northern Kinkaid claims in 2024 (
see news, August 27,
2024
).
This was then followed up by an initial sampling program in the spring of 2025. Early assay
results of
10.6 g/t Au
from quartz veinlets,
3.2 g/t Au
from a brecciated quartzite unit, and scattered
chalcedonic quartz outcrops and float samples that assayed
0.28 to 0.79 g/t Au
provided an incentive
for further sampling in the fall of 2025. Highlights of this most recent sampling include:
1.36 g/t Au across a 50 cm
wide quartz flooded quartzite outcrop;
6.53 and 2.16 g/t Au
from two pieces, each 10-15 cm wide, of a large chalcedonic
boulder/broken subcrop with trace chalcopyrite. A third piece with no visible chalcopyrite assayed
80 ppb Au;
A sample of a small historical stockpile of brecciated quartzite infilled with black manganese
minerals assayed
1.7 g/t Au
.
A sample collected from this site in April 2025 assayed
3.2 g/t Au
(
see news, August 7, 2025
). A chip sample of the fractured quartzite in outcrop 4 metres away
from the aforementioned stockpile contained less manganese but nonetheless assayed
0.33 g/t
Au over 1.4 m
.
While it is sometimes difficult to discern the chalcedonic quartz overprint on the local quartzite and as a
result not all samples taken so far are auriferous, the gold assays returned from the PM zone are still
considered highly encouraging and believed to be indicative of a structurally controlled epithermal gold
mineralizing event. The locally elevated levels of manganese (to 4,760 ppm Mn), mercury (to 617 ppb
Hg) and antimony (to 673 ppm Sb) add further support to this model, as does the presence 30 metres
away of a small stockpile of silver-rich, epithermal-style vein material that has assayed in previous
sampling 495 ppm mercury and 0.25% antimony, elements typically found in epithermal systems, as well
as 1,725 g/t (61 oz/t) silver, 6.9% zinc, 0.4% copper, and 1% lead (
see news, March 10, 2022
).
*Readers should note that grab samples are by their nature selective, and despite our best efforts
may not always be representative of the true style and overall grade of mineralization, nor represent
true widths of mineralization.

About Oreterra Metals Corp.
Oreterra Metals Corp. is a TSXV-listed mineral exploration company focused primarily on gold, copper
and silver. The Company holds several wholly-owned porphyry copper-gold prospects in British
Columbia's Golden Triangle, the most significant of which is the newly-identified Trek South prospect
located to the southeast of Teck-Newmont's Galore Creek project, currently undergoing pre-feasibility
studies. Following a highly successful $9.7 million financing closed earlier this month, a maiden two-
phase, approximately 10,000 metre drill program at Trek South is now fully funded, for completion this
summer.
Drilling will test a 1.6 km wide zone of intense porphyry-style alteration, mineralization and
underlying coincident strong IP, MT and magnetic anomalies exposed by recent glacial retreat. In
addition, the first significant exploration work since 2007 is now planned for Oreterra's JW porphyry
prospect, located to the northwest of the Galore Creek deposits.
Additional wholly-owned interests include two former producers in Nevada: the Kinkaid claims in the
Walker Lane trend covering numerous shallow Au-Cu-Ag workings over what is believed to be one or
more porphyry centres and the Scossa mine property in the Sleeper trend which is a former high-grade
gold producer. The Company also holds a 100% interest in the large-scale Lundmark-Akow Lake Au-Cu
property adjacent to the northwest of the Musselwhite Mine, where past drilling by the Company returned
highly encouraging, broad VMS-style Au-Cu intersections. Oreterra also retains an ongoing interest in
several properties including a 2% NSR on McEwen Mining's Hislop gold property in Ontario and a 2%
NSR on Enduro Metals' Newmont Lake Au-Cu-Ag property in BC.
