Sankamap Resumes Drilling at Kuma; First Assays Pending

Edmonton, Alberta – July 29, 2026 – Sankamap Metals Inc. (CSE: SCU) (“Sankamap” or the

“Company”) is pleased to announce drilling has resumed on its 4,500 -hectare (“ha”) Kuma

Property (“Kuma”) in the Solomon Islands. Drill hole KU26-001 has advanced to a depth of 840

metres ("m"), intersecting multiple zones of mineralization and alteration between 250 m and

840 m (Figure 1).

The planned operational pause allowed the technical team to integrate geological observations

from the initial drilling into a refined geological model, strengthening confidence in the targeting

strategy for the remainder of the program.

The fully funded 2,000 to 3,000-metre drill program is designed to systematically test multiple

high-priority targets across the project's 2 -kilometre-long lithocap , advancing the Company's

understanding of this large-scale hydrothermal system and its mineralization potential.

CEO John Florek commented:

“Steady progress continues as the Company advances the first -ever drill test of this previously

untested lithocap, a geological expression considered prospective for copper and gold

mineralization. Sankamap is the first company to systematically evaluate the potential of this

highly prospective target through diamond drilling.

This pioneering exploration program represents an important step toward assessing the scale and

mineral endowment of a previously unexplored hydrothermal system that the Company believes

has the potential to host a significant copper-gold deposit.

Operating in the Solomon Islands presents unique logistical challenges, but our experienced team

has continued to execute the program safely and efficiently. Strong relationships with local

landowners and government stakeholders have been instrumental in k eeping the project on

schedule, and we look forward to advancing the program and sharing further results as drilling

continues.”

Highlights:

• Targeted surface sampling was completed to generate additional geological insights and

refine priority drill targets during the planned break in drilling operations (Assays

Pending).

• Assays for first 559 m (365 samples) from drill hole KU26 -001 at Kuma have been

submitted and are awaiting results.

• Drilling at Kuma has intersected multiple zones of strong hydrothermal alteration and

abundant sulphide mineralisation . This expression indicates the drill hole has

encountered a robust mineralizing system with significant exploration potential.

• The fully funded initial drill program at Kuma is designed to test and delineate both near-

surface and deeper mineralization , providing the first systematic evaluation of the

project's copper-gold potential.

Discussion

The current drill program at Kuma has been designed to validate the Company's exploration

model while systematically testing high -priority targets generated through the integration of

geological, geochemical, and geophysical datasets . Located within one of the world's most

prospective porphyry copper -gold and epithermal gold belts (Figure 1 ), Kuma benefits from a

geological setting that reinforces the potential for a significant new discovery.

Surface exploration continues to provide encouraging support for the Company's targeting

strategy. Rock samples collected within the interpreted lithocap alteration zone at the drill site

returned up to 3.0 g/t Au. Historical grab samples have yielded up to 13.5 g/t Au and 11.7% Cu.

Initial drilling has intersected multiple intervals of hydrothermally altered volcanic rocks

containing abundant anhydrite veining and disseminated to locally abundant pyrite

mineralization. This style of alteration is interpreted to represent an oxidized magmatic -

hydrothermal system consistent with the upper levels of a porphyry -related environment. The

observed alteration and sulfide assemblages may represent part of a pyrite-rich halo or lithocap

developed above or adjacent to a concealed porphyry copper-gold system at depth. While these

observations are encouraging and consistent with the Company's geological model, additional

drilling and analytical results are required to determine their relati onship to potential economic

mineralization.

Drilling is expected to continue throughout the third quarter, with assay results to be released as

they are received, validated, and interpreted. Sankamap remains committed to conducting

exploration activities safely, responsibly, and in close partnership with local communities while

advancing the Kuma Project toward its next stage of discovery.

About Sankamap Metals Inc.

Sankamap Metals Inc. (CSE: SCU) is a Canadian mineral exploration company dedicated to the

discovery and development of high-grade copper and gold deposits through its flagship Oceania

Project, located in the South Pacific. The Company’s fully permitted as sets are strategically

positioned in the Solomon Islands, along a prolific geological trend that hosts major copper-gold

deposits; Including the nearby Newmont Corporation operated Lihir Mine, which has reported

Proven and Probable Mineral Reserves of 310 Mt grading 2.3 g/t Au containing 23 Moz Au.

Reported Mineral Resources, exclusive of Mineral Reserves, include Indicated Mineral Resources

of 520 Mt grading 2.3 g/t Au containing 39 Moz Au, Measured Mineral Resources of 81 Mt grading

1.9 g/t Au containing 5 Moz Au, and Inferred Mineral Resources of 61 Mt grading 2.3 g/t Au

containing 4.9 Moz Au 1. Mineral resources that are not mineral reserves do not have

demonstrated economic viability. The information disclosed from adjacent properties is not

necessarily indicative to the mineralization on Sankamap’s property.

Exploration is actively advancing at both the Kuma and Fauro properties, part of Sankamap’s

Oceania Project in the Solomon Islands. Historical work has already highlighted the mineral

potential of both sites, which lie along a highly prospective copper and gold -bearing trend,

suggesting the possibility of further, yet-to-be-discovered deposits.

At Kuma, the property is believed to host an underexplored and largely untested porphyry copper-

gold (Cu-Au) system. Historical rock chip sampling has returned consistently elevated gold values

above 0.5 g/t Au, including a standout sample assaying 11.7% Cu and 13.5 g/t Au4; underscoring

the area's significant potential.

At Fauro, particularly at the Meriguna Target, historical trenching has returned highly encouraging

results, including 8.0 meters at 27.95 g/t Au and 14.0 meters at 8.94 g/t Au 5. Complementing

these results are grab sample assays, including historical values of up to 173 g/t Au 5, along with

- 4 -

recent sampling by Sankamap at the Kiovakase Target, which returned numerous high -grade

copper values, reaching up to 4.09% Cu. In addition, limited historical shallow drilling intersected

35.0 meters at 2.08 g/t Au5, further underscoring the property's strong mineral potential and the

merit for continued exploration. With a commitment to systematic exploration and a team of

experienced professionals, Sankamap aims to unlock the untapped potential of underexplored

regions and create substantial value for its shareholders. For more information, please refer to
