Global supply.
U.S. industrial access.
Gatecorp is a U.S. critical minerals midstream company. We develop controlled supply corridors that connect underleveraged strategic mineral production with U.S. industry. Our established focus is tantalum and tungsten, with an expanding portfolio of underleveraged supply opportunities.
Our people have spent decades working on mineral security. When strategic minerals became a national security priority, we saw that one part of the problem remained structurally unresolved. Significant production existed, but conventional U.S. commercial channels could not reliably reach it.
That gap led to Gatecorp.
Gatecorp Strategic Metals was founded to secure underleveraged strategic mineral production and develop supply corridors that carry it into U.S. industrial supply chains. Our approach establishes the access, material provenance and commercial control required to turn that production into processor-ready feedstock for U.S. industry.
Gatecorp is a member of the Defense Industrial Base Consortium (DIBC) and of the Cornerstone Other Transaction Agreement (COTA) consortium, the Department of War's only government-managed consortium operating under Other Transaction authority. In April 2026, Gatecorp's proposed prototype project received a Met rating in Phase 1 of a Department of War (DoW) solicitation to strengthen critical mineral supply chains, based on DoW criteria for relevance, merit and feasibility.
Founder and CEO Mayer Ngomesia brings nearly two decades of experience across strategic minerals, industrial systems and mineral security, with on-the-ground engagement spanning over 38 countries across Africa, the Middle East, Europe, Asia and the Americas. Gatecorp is supported by a lean team and advisors spanning technical processing, commercial development, and national security.
1/ Who We Are
Grounded in Mineral Security
2/ What we solve
Commercial availability is not strategic access.
Critical minerals may be readily available through established global markets, yet still be difficult to source on terms acceptable to the U.S. Defense Industrial Base. Defense sourcing brings tighter origin, provenance and supply-chain requirements, while relatively small defense demand can limit its ability to reshape established commercial flows.
Gatecorp focuses on that gap. We target underleveraged production where material provenance, commercial structure and control can create strategically accessible supply for U.S. industry and the Defense Industrial Base.
3/ what's at stake
Scale of strategic exposure.
For tantalum and tungsten, the numbers reveal the scale of the supply exposure.
2027
U.S. Defense
procurement restrictions
From January 2027, DFARS restrictions will extend to the upstream origin of covered tantalum and tungsten. Material mined or produced as ore or feedstock in covered countries will be restricted from covered DoD procurement.
Origin and control of the upstream supply chain therefore become materially more consequential for defense sourcing.
52-74%
Fragmented
Production
Over half of global tantalum mine supply comes from dispersed African production beyond the reach of conventional U.S. sourcing channels.
The Defense Industrial Base cannot close its supply gap while strategically significant production remains commercially inaccessible.
~80%
Concentrated
Supply
Over 80% of global tungsten mine production originates from a single foreign supply base.
The relatively small share available outside that concentrated channel therefore carries disproportionate strategic value.
100%
Supply
Reliance
The United States remains 100% net import reliant for tantalum.
Diversified access to global supply is therefore fundamental to reducing upstream exposure.
