ANGKOR RESOURCES REPORTS VISUAL COPPER MINERALIZATION IN

2026 DRILL CORE FROM ANDONG BOR LICENSE, CAMBODIA

GRANDE PRAIRIE, ALBERTA (September 1, 2026): ANGKOR RESOURCES CORP. (TSXV: ANK

OTCQB: ANKOF) (“ANGKOR” OR “THE COMPANY”) announces preliminary geological observations

from the logging of diamond drill core completed during the first phase of 2026 drill program at

the Thmei North (“TN”) target on the Andong Bor mineral exploration license in Cambodia (see

ANGKOR RESOURCES DRILLS INITIAL PROGRAM AT ANDONG BOR COPPER-GOLD

TARGET, CAMBODIA – Angkor Resources Corp). The Company is currently splitting the 2026

drill core in preparation for sending samples to ALS in Phnom Penh for analysis.

OBSERVARTIONS AT A GLANCE

• The best copper mineralization in the Andong Bor core is hosted by metasedimentary rocks.

• Assay values from the feldspar porphyry intrusive rocks are mostly at or below 2,000 parts per

million (ppm) copper; values increase dramatically in proximity to the highly reactive wall rock.

• Visually significant copper mineralization was observed as chalcopyrite occupying fractures in

the metasedimentary rocks, and as ‘B’ and ‘D’ veins in the intrusive rocks.

• The structural relationship between the intrusive rock and the host sedimentary rock has now

been revealed for the first time: contacts are very steep, from 70 to 80 degrees.

• Hole AB26-012D cored pyrite-dominant mineralization frequently downdip for the first 200

meters from the surface, suggesting the possibility of gold mineralization.

The Andong Bor license is 100.28 square kilometers and straddles Oddar Meanchey and Banteay

Meanchey provinces. Thmei North is located on relatively flat farmland and is defined by an

approximately one-square-kilometer copper-in-auger-soil anomaly. The three new holes

(ABDDH26-010 to -012) are visually similar to previously drilled holes and should return similar

analytical results.

Visually, it is clear that the best copper mineralization in the Andong Bor diamond drill core is

hosted by the metasedimentary rocks. Although the feldspar porphyry intrusive rocks can host

copper porphyry style mineralization, such as ‘B’ and ‘D’ style veins and disseminations, the values

from assay to date are mostly at or below 2,000 ppm copper. In proximity to the highly reactive

wall rock, assay values increase dramatically. These are the observations made by examining the

diamond drill holes from the 2016 drill program.

The drilling in 2026 was designed to better intersect the north-south trending, steeply east

dipping bands of intrusive dikes and highly reactive metasedimentary rock. The drilling did this

quite successfully, resulting in some visually significant copper mineralization in the form of

chalcopyrite occupying fractures in the metasedimentary rocks, and both ‘B’ and ‘D’ veins in the

intrusive rocks.

Dennis Ouellette, VP Exploration, comments: “Visually it is clear that the best copper

mineralization in this core is hosted by the metasedimentary rocks. The intrusive can carry

porphyry style mineralization — the ‘B’ and ‘D’ veins and the disseminations are there — but

assays to date from the intrusive are mostly at or below 2,000 ppm copper. In proximity to the

highly reactive wall rock, the values increase dramatically. That is exactly what these holes were

designed to intersect, and the core we are splitting now looks very much like the holes we have

drilled before.”

STEEP CONTACTS AND GROUND PREPARATION

The structural relationship between the intrusive rock and the host sedimentary rock was not

revealed in the previous drilling (ABDDH16-005, -006, -007 and -008), as all the contacts were

faulted or there was poor core recovery at those sites. The 2026 drilling has now shown that the

contacts are very steep — from 70 to 80 degrees. Mineralization within the sediments is both

disseminated and along fractures parallel to these contacts. This implies significant ground

preparation pre intrusion and mineralization.

H O LE AB2 6- 012D — PYRITE AND A POSSIBLE GOLD SIGNATURE

Hole AB26-012D was testing the western boundaries of the copper mineralization, approximately

150 metres further east of any previously drilled hole and well within the greater than one square

kilometre copper-in-auger-soil anomaly. Preliminary observation suggests poor copper

mineralization, although abundant pyrite-dominant mineralization suggests the possibility of gold

mineralization, as it does descriptively resemble other gold targets in the Loei Fold Belt. Dominant

pyrite mineralization is frequent for 200 metres from surface. This could be a different phase of

the same mineralizing event, or an entirely different event.

Ouellette adds: “The third hole is a different story. There is very little copper in it, but there is a

great deal of pyrite — frequently for the first 200 metres from surface — and it descriptively

resembles other gold targets in the Loei Fold Belt. It could be a different phase of the same

mineralizing event, or an entirely different event. The assays will tell us which.”

O P ERATIO N S

Core from the first phase of the 2026 program is being logged, photographed and split at the

Company’s core facility, with samples dispatched to ALS in Phnom Penh for analysis. Results will

be reported as they are received and interpreted.

N EXT STEP S

Next steps will continue to find the boundaries of the copper mineralization both on Thmei North

and also on Thmei South, which remains largely unexplored. Thmei South is located roughly three

kilometres to the south of Thmei North and requires further auger soil geochemistry to extend

the existing copper geochemical anomaly and determine its full extent. The second phase of the

Thmei North drill program and activity on Thmei South will continue in 2027, once the fields are

dry and the crops have been harvested.

ABOUT ANGKOR RESOURCES CORP.

ANGKOR Resources Corp. is a public company, listed on the TSX -Venture Exchange, and is a leading resource

explorer and developer in Cambodia working towards mineral and energy solutions across the country. The

Company’s mineral subsidiary, Angkor Gold Corp. Co., Ltd., currently holds two mineral exploration licenses in

Cambodia with multiple prospects in copper and gold. Both licenses are in their first two-year renewal term.

Angkor’s Cambodian energy subsidiary, EnerCam Resources Co., Ltd., was granted an onshore oil and gas license

in the southwest quadrant of Cambodia called Block VIII. The license covers an area of approximately 4095 square

kilometers. EnerCam is actively advancing oil and gas exploration activities onshore to meet its mission to prove

Cambodia as a nation with its own oil and gas resources. The Company completed 2D -seismic in 2025 and has

identified multiple drill targets with multiple target zones. The Company plans to follow with drilling Cambodia’s

first privately financed onshore exploratory oil and gas wells under a Production Sharing Contract.
