A private house for trade, capital, and enterprise operations.
MGK Enterprises LLC has built and brokered across commodities, minerals, and structured finance for two decades — and now delivers those disciplines through four working divisions.
Four divisions, one standard of execution.
Each division runs on the same principle: disciplined documentation, verified counterparties, and terms that hold up to scrutiny.
International Trade
Sourcing, brokerage and structured transactions across petroleum, refined products, LNG, metals, grain and minerals.
- Crude & refined product (EN590, and related)
- Mineral & commodity offtake
- Charter party & logistics coordination
- Counterparty due diligence
Minerals and Refining
Through its affiliate AMTSK: purchase, sale and export of raw minerals, including silver, antimony, gold, zinc and copper, sourced from Bolivia, refined through a third-party refinery in Las Vegas, Nevada, and at the group's own facilities in Victorville, California, on the East Coast, and in South Korea.
Monetary Platform
Structured-finance documentation and platform services.
- Transaction structuring & documentation
- Escrow & paymaster coordination
- Fee-protection & agency agreements
- Compliance-first execution
Keystone Response Group
Business-process operations, marketing, phone response, live chat and administrative support.
- Corporate contact-center services
- Inbound, transfer & live-chat handling
- Billing & administrative support
- TCPA / DNC compliant operations
The cargoes we move and finance.
From crude and refined product to LNG, containerized freight, and physical commodities — the assets behind the paper.
Two decades of building where trade meets capital.
MGK Enterprises LLC is a member-managed Nevada limited liability company, established in 2004 (Nevada Business ID NV20041157103). It is the parent trading house of the group and does business as Keystone Response Group.
MGK Enterprises LLC is affiliated, under common ownership, with Advanced Minerals Technology S Korea Inc. (AMTSK), an Arizona minerals company, through which the group runs its mine-to-refinery mineral supply chain.
Our history
Two decades of physical trade, built house by house.
MGK Enterprises LLC was founded in Nevada in 2004 and has operated continuously through that same house ever since. What began as direct, door to door commodity trading on the corridor from Ghana to Singapore grew, deal by deal, into precious metals, petroleum, liquefied natural gas, diamonds, minerals and industrial minerals, and today into clean technology, energy storage, and enterprise operations. The through line has never changed: hands on knowledge of physical cargo, paired with the documentation discipline that international counterparties and banks require.

2004
MGK Enterprises LLC founded, Nevada
Established as a private trading house. In the early years the work was direct and unglamorous: door to door commodity trading on the corridor from Ghana to Singapore. MGK remains the parent through which every later venture has run.
-
Singapore
Partnership with MGK Gold and Silver
Entered a partnership in Singapore and, after several years, opened an office there under that name. This became the first permanent Asian presence and the source of trading relationships that still underpin the group's Southeast Asian network.
-
Dubai
MGK Dubai office established
When his two partners relocated to India, the founder returned to Dubai and established the MGK office there. The Dubai platform opened the Gulf, and with it, the energy trade.
-
Abu Dhabi
Entry into the petroleum trade
Through introductions in Abu Dhabi, the firm met holders of jet fuel allocation and executed its first jet fuel shipment to Dalian, China. That transaction marked the transition from metals into energy.
-
Growth
Oil and LNG across Singapore and Dubai
The firm built out counterparty networks across both hubs and entered the crude, refined product, and liquefied natural gas trades, all conducted through MGK.
-
Minerals
First mineral transaction, cobalt from the DRC
The first mineral trade was cobalt out of the Democratic Republic of the Congo. The founder tested the raw material in South Korea and completed the transaction there, establishing the Korea refining relationship the group's mineral business still rests on today.
-
Diamonds
African rough into Singapore
The firm extended into the diamond trade, moving African rough exclusively into the Singapore market.
-
2020
Green Energy Global Inc. incorporated, Arizona
Formed as the clean technology and energy arm of the group, trading as Green Power Tech, and later the parent of Advanced Minerals Technology S Korea Inc.
-
2024
Advanced Minerals Technology S Korea Inc. incorporated
Established to run a mine to refinery mineral supply chain from Potosi, Bolivia, through the Chilean port of Arica, to the Port of Pyeongtaek and a refinery in Gyeonggi-do, South Korea, with a Bolivian subsidiary in Potosi.

Today
One house, four working divisions
The same discipline now carries into four divisions: international trade, minerals and refining, the monetary platform, and Keystone Response Group operations, under a single chairman and a single standard of execution.
Keystone Response Group
The firm’s business-process operations arm — a corporate contact and sales organization built to carry telecom and enterprise programs at scale, entirely from our Nevada office.
Built for volume, run on compliance.
Keystone pairs a trained agent floor with the documentation discipline the rest of the firm is known for — every calling program runs inside TCPA, DNC, and privacy rules.
Phone Response
Inbound and transferred-call handling with in-policy presentation of approved offers and clean order capture.
Live Chat
Concurrent chat coverage, qualification, and warm hand-off to agents — bilingual where required.
Administration
Billing support and tax-document handling within a defined scope — administrative work, not tax preparation.
Compliance
TCPA, DNC, CPNI, and privacy procedures maintained and applied to every calling and data-handling task.
Documentation first. Always.
Every engagement moves through the same disciplined path — because in trade and capital, the paperwork is the deal.
Verify
Counterparties, instruments, and mandates are checked before anything is papered. Nothing advances on assumption.
Structure
Terms are drafted to hold — clear scope, real protections, and mechanics that survive counsel review on both sides.
Execute
Signed, sealed, and administered with the same rigor through closing and performance, not just at signature.
Open a conversation.
Serious inquiries from counterparties, institutions, and partners are welcome. Tell us the nature of the engagement and we will respond.
