Vancouver, British Columbia--(Newsfile Corp. - January 28, 2026) -
Altamira Gold Corp. (TSXV:
ALTA) (FSE: T6UP) (OTCQB: EQTRF)
("
Altamira
" or the "
Company
")
,
is pleased to report assay
results from recent resource-extension drilling at the Cajueiro Central project, Brazil.
Highlights:
The first five diamond drillholes targeting extensions and resource infill at the Cajueiro Central
mineral resource have been completed. The drillholes intersected brecciated hydrothermal quartz
structures with associated sericitic alteration halos, hosted in rhyolites, consistent with the
geological model established by previous programs.
Hole CJO 114, drilled outside the current resource, returned
7.5m @ 1.02g/t gold
from 1.9m
depth and
5m @ 1.46g/t gold
from 112m depth, confirming that mineralization extends beyond the
existing resource boundaries.
Drillhole CJO 117, drilled within the current resource, returned intercepts of
2.3m @ 6.1g/t gold
from 34m and 2.9m @ 1.7 g/t from 78m depth. The upper interval included
0.7m @ 19.0g/t gold
,
representing the highest-grade primary intercept reported to date in the Baldo sector of the
Cajueiro mineral resource, and indicating potential for higher grade shoots within the established
mineralized structures.
Drilling is also in progress at two high-priority and previously untested porphyry targets at
Mombaque and Guillermo which are located within the Maria Bonita - Morro Verde trend.
CEO Mike Bennett commented; "Drilling continues to advance both within and around the Cajueiro
Central resource, in tandem with drilling of several previously untested porphyry targets across the
Cajueiro district. Results from initial drillholes in the current program at Cajueiro Central confirm the
style, width and grade of structures extending laterally beyond the existing resource. Our objectives
are to add additional ounces to the current inventory and to increase confidence in the existing
resource estimate by converting Inferred resources to Indicated resources. Our second drill rig is
focused on the initial drill testing of the previously untested
district targets at Mombaque and
Guillermo. Together with ongoing drilling at the Cajueiro and Maria Bonita mineral resources, we
expect this will generate a steady flow of drill results in the coming months."
CAJUEIRO DISTRICT
The Cajueiro district is located approximately 75km NW of the town of Alta Floresta in the state of Mato
Grosso (Figure 1) in central western Brazil. The project is easily accessible by road, lies on open
farmland and has grid power and a local water supply. Cajueiro is the most advanced of the key projects
that Altamira controls in the region (Figure1).

The Cajueiro district consists of two independently estimated gold mineral resources at Cajueiro Central
and Maria Bonita, plus a series of eight additional untested exploration targets within a radius of 8km of
Cajueiro Central.
The Cajueiro Central area has a current open pit resource
1
of 5.66Mt @ 1.02 g/t gold for a total of
185,000 oz in the Indicated Resource category and 12.66Mt @ 1.26 g/t gold for a total of 515,000 oz in
the Inferred Resource category (estimated using a cut-off grade of 0.25g/t Au and a gold price of
US$1,500/oz).
The Maria Bonita open-pit resource consists of Indicated Resources of 24.19Mt @ 0.46g/t gold (for a
total of 357,800oz) and Inferred Resources of 25.64Mt @ 0.44g/t gold (for a total of 362,400oz)
2
. These
resources were calculated using a 0.2 g/t gold cut-off grade and a gold price of US$2,780/oz. These
resources include near-surface saprolite Indicated Resources of 2.02Mt @ 0.59g/t gold (38,000oz) and
Inferred Resources of 0.68Mt @ 0.40g/t gold (8,700oz).
The Maria Bonita porphyry gold deposit forms part of a district-scale portfolio of prospects that are
interpreted as having a similar geological origin (Figure 2). The Cajueiro area is characterized by a
15km stretch of former alluvial gold workings along the Teles Pires river. The source of some of this
alluvial gold is related to a pronounced east-west corridor of gold anomalies in soils and rock chips and
a set of sub-cropping intrusions extending east-west over 8km, implying the presence of a long-standing
and deep-seated crustal structure.

prospects (blue labels with scout drilling, yellow labels not yet drilled). An alignment of six of the targets
occur in close spatial association to a pronounced east-west fault corridor marked by later gabbroic
dykes.

Cajueiro Central Drilling Update
The Cajueiro Central resource includes several subsectors, with the majority (54%) of contained gold
within the northern Baldo subsector (Figure 3).

Drillholes CJO 113 and 114 partially tested a broad zone of alteration related to the SW extension of the
Baldo "A" structure (Figure 4). This alteration zone contains a zone of 17m @ 1.46g/t gold in trenching
which is interpreted as not having been intersected by CJO113 and which will be further drill tested as
indicated in Figure 5. Where drilled further north, the Baldo "A" structure dips to the east, whereas the
trenched interval is currently interpreted to be sub- vertical.
Drillhole CJO115, which lies outside the resource, intersected a low-grade zone of modest width. Holes
CJ0116, 117 and 118 all intersected structures carrying grades >3g/t gold, albeit of relatively narrow
widths. The intercept of
0.7m @ 19g/t gold
in CJO117 (34.9-35.6m) indicates the presence of high-
grade primary gold mineralization in a near surface location. This is the highest primary gold grade found
to date in drilling in the Baldo sector of the Cajueiro Central resource. Baldo is the largest sector of the
resource in terms of contained ounces of gold.

Mombaque and Guillermo Targets
Drilling has commenced at the previously untested targets Mombaque and Guillermo (Figure 2). The
Mombaque prospect, located about 1.6 km east of the Maria Bonita discovery, hosts a significant gold-
in-soil anomaly with porphyry-style alteration and quartz veining at surface that suggests a concealed
mineralized system ripe for drilling (see October 16, 2024 press release). At the Guillermo target, 2.5 km
northeast of the Cajueiro Central area, rock grab sampling returned high-grade gold up to 39 g/t and
surrounding soil anomalies outline an extensive target area now being drill tested for the first time (see
December 11, 2024 press release).
New Exploration Camp
The Company has completed construction of a new, low-cost modular exploration camp at its Maria
Bonita property (Figure 6). The facility comprises container accommodation, a site office, and purpose-
built core logging and sample preparation areas. The Maria Bonita camp is expected to materially
enhance logistics and operating efficiency for exploration and project development in the western
Cajueiro license area.

About Altamira Gold Corp.
The Company is focused on the exploration and development of gold projects within western central
Brazil, strategically advancing five projects spanning over 100,000 hectares within the prolific Juruena
Gold Belt-an area that has historically yielded over 6 million ounces of placer gold
3
. The Company's
advanced Cajueiro project contains two gold deposits. The central area comprises NI 43-101 resources
of 5.66Mt @ 1.02 g/t gold for a total of 185,000 oz in the Indicated Resource category and 12.66Mt @
1.26 g/t gold for a total of 515,000oz in the Inferred Resource category. In addition, the Maria Bonita gold
deposit comprises additional open pit Indicated Resources of 24.19Mt @ 0.46g/t for a total of
357,800oz, and Inferred Resources of 25.64Mt @ 0.44g/t for a total of 362,400oz.
Ongoing exploration and fieldwork at Cajueiro indicate the presence of multiple porphyry gold systems,
reinforcing its potential for district-scale development. These hard-rock gold sources align with historical
alluvial gold production, highlighting the region's exceptional gold endowment and potential scalability.
With two independently established mineral resources, a highly prospective geological setting and a
track record of significant discoveries, the Company is well-positioned to unlock further value across its
extensive land package.

Quality Assurance/Quality Control
Drillholes commence in HQ diameter (63.5mm) and proceed to the base of weathering where core
diameter is reduced to NQ (47.6mm). Logging and sampling are completed at a secure Company
facility located on site. Drill core is cut in half on site by a saw cut or slicer (in soft saprolite).
Until dispatch, samples are stored under the supervision the Company's exploration office. The
samples are couriered to the assay laboratory using a commercial contractor. Pulps are returned to
the Company and archived.
For all drilling, half core is submitted to SGS Geosol, a leading commercial laboratory in Brazil and
analysed for gold by 50g fire assay, plus a suite of other elements by the ICP atomic absorption
method, using standard laboratory procedures. Soil and rock chip samples follow the same analytical
protocol.
Quality control of drillhole assays follows normal industry procedures of inserting control samples
randomly into the submitted batch, comprising field duplicates, independent reference samples and
"blank" samples. Selected batches of sample pulps are periodically resubmitted to a third-party
laboratory to check the main laboratory precision and accuracy.
Drill holes results are quoted as down-hole length weighted intersections.
