Altamira Gold Mobilizes Drill Rig to Cajueiro Gold District, Brazil
Altamira Gold Mobilizes Drill Rig to Cajueiro
Gold District, Brazil
Vancouver, British Columbia--(Newsfile Corp. - July 17, 2025) -
Altamira Gold Corp. (TSXV: ALTA)
(FSE: T6UP) (OTCID: EQTRF),
("
Altamira
" or the "
Company
") is pleased to announce the
mobilization of a diamond drill rig to the Cajueiro gold Project, in Brazil. Drilling will initially focus on
testing depth and lateral extensions to the recently defined maiden mineral resource at Maria Bonita,
followed by the drill testing of several recently identified porphyry targets within the Cajueiro district.
Highlights:
A diamond drill rig has been mobilized to the Cajueiro Gold District. An initial 3000m program of
eight holes is planned to test for extensions to the recently identified Maria Bonita gold deposit,
which remains open to the west, south and at depth
Maria Bonita is the first of nine porphyry-gold targets that have been identified so far within the
Cajueiro District, with maiden drill programs planned on a number of these targets in the coming
months
To support the forthcoming drill program and expedite logistics, the Company has commenced
construction of a simple and fit-for-purpose development camp at Maria Bonita
CEO Mike Bennett commented; "Following the recent successful and over-subscribed private
placement financing, we are mobilizing an initial diamond drill rig to the Cajueiro Gold District. Drilling
will commence with target extensions to the Maria Bonita gold deposit. We have some very promising
opportunities to extend the drill coverage laterally and at depth where the current resource shell is
unconstrained. Following the commencement of the drill program at Maria Bonita, the program will
expand to include several of the other identified peripheral porphyry gold targets within the Cajueiro
district. This should result in a regular stream of drill results over 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 (Figure1).

The Cajueiro district consists of two independently estimated gold mineral resources at Cajueiro Central
(105 drillholes; 14,353m) and Maria Bonita (29 drillholes; 4,518m) - both reported under NI 43-101, plus
a portfolio of eight additional untested exploration targets within a radius of 8km at 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 centre of the mineralized zone at Maria Bonita is interpreted as dipping to the south, therefore
planned drillholes will be inclined to the north to test the depth and southern lateral continuity of the main
mineralized body. The best drillhole to date (MBA029) intersected
212.8m @ 0.8g/t gold from surface
.
Initial drilling in the forthcoming program will be directed at better defining the limits of this part of the
resource.
The Maria Bonita porphyry gold deposit is interpreted as part of a district-scale, porphyry-related
mineralizing event. There are currently eight additional porphyry gold targets awaiting scout drill testing
over an 8km radius from the Cajueiro Central resource (Figure 2). Three partially tested drill targets lie
outside the current Cajueiro Central mineral resource. Drilling is planned for these targets and will
commence as soon as a second rig becomes available.

To support the forthcoming drill program, a simple and fit-for-purpose containerised project development
camp will be constructed at Maria Bonita to expedite logistics, in combination with the existing camp at
Cajueiro Central. Second hand containerised facilities have been ordered to minimize costs and will
arrive on-site in 30 days.

About Altamira Gold Corp.
The Company is focused on the exploration and development of gold and copper 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**. 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.
