GOLDSTRATEGIC COMMODITYPARTNERSHIP-BASED DEVELOPMENT & TRADING

CONNECTING GOLD RESOURCE PARTNERS TO MARKET.

AT Corporation approaches gold opportunities through partnership-based resource access, including Joint Operation and structured commodity purchase arrangements with mining and license-holding partners.

Commercial and trading execution is routed through PT Aneka Tambang Perkasa (ATP), the Group’s Mining & General Commodities Trading Arm.

PARTNERSHIP-BASED RESOURCE ACCESS

FROM PARTNER RESOURCE TO MARKET.

Current gold participation is structured with mine or IUP-holder partners through Joint Operation and/or purchase contracts, subject to legal, technical, quality and commercial validation.

Partnership access and contracted supply do not constitute AT Corporation ownership of the underlying IUP or gold resource.

STRATEGIC RESOURCE

GEOLOGY FIRST. CAPITAL SECOND.

Gold development depends on more than mineral presence. Geological continuity, grade distribution, metallurgy, mining method, infrastructure and development economics must be validated together.

AT Corporation’s Gold strategy is structured around disciplined technical evaluation and selective project development.

Current Gold participation is partnership-based through mine or IUP-holder cooperation, Joint Operation and/or purchase contracts. AT Corporation does not own the underlying partner IUP and does not present any Gold concession, mine, project, resource, reserve, production, processing facility or refinery as an owned verified public asset.

STRATEGIC RATIONALE

PRECIOUS METAL. RESOURCE DISCIPLINE.

01

RESOURCE VALUE

Gold projects can create substantial resource value where grade, continuity, recovery and mineability are technically supported.

02

GEOLOGICAL UPSIDE

Exploration can increase project value only when geological interpretation and data quality support further investment.

03

PROCESSING OPTIONALITY

Metallurgical characteristics determine which processing routes may be technically and economically appropriate.

04

GLOBAL MARKET ACCESS

Gold is globally traded, but project economics remain highly dependent on recovery, cost structure and development discipline.

AT Corporation’s broader mining-services architecture provides operating capability that may support future mineral developments where project requirements and commercial structures are aligned.

PT Batu Mutiara Hitam does not currently operate a Gold mine.

COMMERCIAL CONNECTIVITY

FROM MINERAL PRODUCT TO MARKET.

PT ANEKA TAMBANG PERKASA
ATP — MINING & GENERAL COMMODITIES TRADING ARM

PT Aneka Tambang Perkasa supports gold commodity origination, partnership-based supply, purchase contracts, Joint Operation commercial support, trading and market connectivity, subject to the applicable contractual structure.

ATP is the commercial executor and is not represented as the owner of a gold IUP.

DEVELOPMENT DISCIPLINE

EXPLORE. DEFINE. TEST. DEVELOP.

01

OPPORTUNITY IDENTIFICATION

Identify Gold opportunities that fit the Group’s strategic, technical and commercial criteria.

02

LEGAL / LICENSE REVIEW

Confirm license status, ownership, land position and regulatory requirements.

03

GEOLOGICAL VALIDATION

Confirm the geological model and mineralization controls before committing significant exploration capital.

04

EXPLORATION

Build sufficient geological and assay data to test continuity, grade and scale.

05

RESOURCE DEFINITION

Develop a technically supportable resource model under an appropriate reporting framework.

06

METALLURGICAL VALIDATION

Determine recovery characteristics and the appropriate processing pathway.

07

ECONOMIC / FEASIBILITY ASSESSMENT

Evaluate mine design, processing, infrastructure, capital, operating cost and market assumptions.

08

PROJECT DEVELOPMENT

Advance only when geological, technical, legal, environmental and economic conditions are sufficiently supported.
