Encouraging Early Signs of Large Gold-Copper System
Identified at Kuma
Edmonton, Alberta – May 27, 2026 – Sankamap Metals Inc. (CSE: SCU) (“Sankamap ” or the
“Company”) is pleased to provide an update on its inaugural drill program at the Kuma Property
in the Solomon Islands. The Company has identified encouraging early signs of a potentially
significant gold-copper system, including elevated surface gold values near the first drill hole and
strong alteration and sulphide mineralization encountered during drilling. These results support
the Company’s belief that Kuma may host a large mineralized system at depth.
Highlights:
• Grab samples near the initial collar location have returned samples of up to 3.0 g/t Gold
(Au) as shown in Image 1.
• Elevated proximal water samples to drillhole are 10x Copper (Cu) over pristine levels.
• Drilling has currently intersected several alteration zones and in particular an intensely
clay-altered zone characterized by abundant anhydrite veining and pyrite occurred at
250.0 m to 280.5 m depth. Drilling of KU26-01 is ongoing.
CEO John Florek commented:
“The combination of strong surface gold results, elevated copper values in nearby water samples,
and encouraging alteration encountered in our first drill hole provides early evidence of a large
and active mineralizing system at Kuma. The drilling intersec ted strong alteration, veining, and
sulphide mineralization that are commonly associated with porphyry -related gold- copper
systems. These early results support our geological model and reinforce the potential for a
significant discovery at depth or nearby.”

Discussion
This program is designed to validate our exploration model and deliver value for our shareholders
(see Figure 1 ). Importantly, our work is situated within a highly prospective jurisdiction (see
Figure 2 below), reinforcing the broader potential for significant discovery.
We have identified a surface rock sample grading 3.0 g/t Au at the drill site within the interpreted
lithocap alteration zone. This result, together with copper values in nearby surface waters
elevated by up to ten times above typical pristine background l evels, further supports the
prospectivity of the Kuma targets during this first phase of drilling.
Water samples collected from a nearby stream proximal to the drill area also returned anomalous
geochemical values, including:
- 6 -
• Aluminum: 4.54 mg/L
• Copper: 0.221 mg/L
• Manganese: 0.499 mg/L
• Iron: 3.28 mg/L
Copper concentrations in the water are considered significantly elevated relative to normal
pristine background conditions, which are typically equal or below 0.02 mg/L Cu. The metal
content is interpreted to be associated with pyrite-rich hydrothermal alteration and active sulfide
weathering within the system.
Drilling has now intersected multiple intervals of hydrothermally altered volcanic rocks
containing abundant anhydrite veining and abundant pyrite mineralization . This style of
alteration is interpreted to reflect an oxidized magmatic -hydrothermal system consistent with
the upper levels of a porphyry -related environment. The observed sulfide and alteration
assemblage may represent part of a pyrite -rich halo or litho cap developed proximal to a
potentially concealed porphyry center nearby (see image 2 and 3).
Strategic Targeting at Kuma
• Initial drill campaign at Kuma planned for approximately 2,000 to 3,000 meters.
• Focus on several priority targets with strong geophysical and geochemical signatures.
• Fully funded program with flexibility for expansion based on results.
• Geophysical anomalies coincident with lithocap features are being integrated to refine
collar locations and drill orientations.
The Company’s technical team has identified several compelling targets at Kuma characterized
by a significant, yet untested, leached lithocap which is generally associated with epithermal
and porphyry Cu-Au systems. Recent fieldwork has outlined an extensive lithocap zone marked
by advanced argillic alteration, including alunite, kaolinite, and residual silica. Such lithocaps are
commonly linked to high -sulfidation epithermal systems and may represent the uppermost
expression of potentially mineralized hydr othermal systems at depth, often spatially
associated with gold and copper mineralization. Collectively, these geological features are
considered highly prospective and consistent with regional geological trends indicative of
significant mineral deposit potential; however, their economic significance has not yet been
determined.
The scale of mineralization encountered across the property underscores its significant discovery
potential. No historical drilling has been conducted on the Kuma Property

Drilling operations are expected to continue through Q2 & Early Q3 , with assay results to be
released as they become available and are validated. Sankamap remains committed to
conducting all exploration activities in a safe, environmentally responsible, and community -
conscious manner.
Quality Assurance and Control Procedures
Water and rock s ample preparation and analysis was completed at the Brisbane, Australia ALS
Global Facility accredited by the National Association of Testing Authorities (NATA) and compliant
with international standards ISO/IEC 17025. Rock s amples were analyzed using Four acid
digestion methods on 34 elements: HF-HNO3-HCIO4 acid digestion, HCL leach and ACP-AES. Gold
was analyzed using the Fire Assay technique with a 50g sample under the ALS code Au -AA26.
Water samples were tested using ALS drinking water s chedule 3, to detect dissolved metal
concentrations, general water quality identification of any potential health concerns. A secure
chain of custody procedure was maintained in storing and transporting all samples. Sankamap
uses industry standards for collecting samples taken on the Kuma property, internal quality
assurance and quality control (QAQC) procedures were followed by ALS.

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 assets 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.
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
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
