NZ Mineral Estate: Legacy Resources and Emerging Opportunities

A Vast and Strategic Mineral Footprint

NZ Legacy owns nearly 1 million acres of mineral rights spanning northern Arizona, New Mexico, and southern Colorado, making it one of the largest private mineral estates in the western United States.

Of these holdings:

• 305,000 acres lie beneath the Navajo Reservation.

• Over 200,000 acres are located beneath Navajo Allottee lands in New Mexico.

• Additional acreage exists under or adjacent to federal and tribal lands, often with split estates between surface and mineral ownership.

In 2002, Congress passed, and President George W. Bush signed into law, a precedent-setting bill allowing the former owners of NZ to transfer their mineral rights beneath a small Acoma/Pueblo reservation in New Mexico in exchange for cash or federal lands of equal value. This legislative “trial balloon” successfully demonstrated the federal government’s willingness to perfect or “unify” title to tribal land by compensating private mineral owners.

Based on this success, NZ anticipates the potential to monetize significant portions of its reservation-based mineral estate—either through direct compensation, federal land exchanges, or development partnerships. This pathway represents one of the most immediate sources of value within NZ’s mineral portfolio.

A Century of Geological Discovery

NZ’s mineral legacy dates back to 1917, when geologist Andrew C. Lawson conducted a comprehensive survey of the company’s lands in Arizona and New Mexico. His report noted:

• Coal seams in the Mesa Verde formation near the Valencia Tract.

• Gold placer potential along the western edge of the Mohave Tract.

• An oil sand outcrop in the McKinley Tract, suggesting future drill potential.

While some areas lacked immediate promise, others were identified as worthy of deeper exploration—especially for coal and oil-bearing formations.

In the 1990s, geologist J.D. Sphar conducted a broader review of NZ’s mineral estate, concluding that the following minerals had been discovered or indicated within company-owned subsurface rights:

• Petrified Wood

• Coal

• Potash

• Kaolin (Industrial Clay)

• Uranium

• Travertine

• Oil

• Helium

These resources reflect both historical discoveries and modern relevance—particularly helium, uranium, potash, travertine and kaolin clay which are increasingly strategic in today’s energy and technology markets.

Forward-Looking Value

NZ Fee Minerals: Proven Resources with Untapped Potential

These holdings are not only historically significant but also strategically valuable, representing both proven resources and speculative upside in underexplored formations. The estate spans diverse geological zones known to host critical energy and industrial minerals.

Dual Value: Tangible Resources and Speculative Potential

The value of NZ’s mineral estate rests on two pillars:

1. Known Resource Deposits: Including uranium, travertine, coal, potash, industrial clays, oil, and petrified wood—discovered and documented through decades of exploration.

2. Intrinsic and Speculative Worth: Mineral rights are titled real property—an estate with enduring legal and speculative value. Even where economic extraction is not yet viable, untapped potential remains, especially when geologic investigation can increase value through future discoveries or shifting market dynamics.

Summary of Key Resources

Uranium

Uranium is among the most economically promising minerals on NZ’s lands. In the Crownpoint–Hosta Butte region of New Mexico, well-defined deposits contain an estimated 55 million pounds of uranium, which is amenable to in-situ leach (ISL) mining at costs of nearly $20 per pound.  The Hansen Deposit in Colorado has an additional 35 million pounds of Uranium.  Historically, this resource generated over $1 million in leasehold revenue. As global demand for clean nuclear energy increases, these deposits remain a core strategic asset.

Travertine (Calcium Carbonate)

Located on NZ’s checkerboard lands along Mesa del Oro, west of Albuquerque, this billion-ton deposit of travertine limestone (over 95% calcium carbonate) is well-defined by drilling. NZ holds six full sections (surface and minerals). Potential uses include:

• Flue gas scrubbing for power plants

• Cement and lime production

• Dimension stone and decorative tile

• Road base, ballast, and rip-rap aggregate

  This deposit is poised for future commercial development.

Petrified Wood

Once the world’s largest commercial deposit, NZ’s petrified wood holdings were absorbed mainly by the creation of the Petrified Forest National Park in 1906. Remaining deposits on the Milky Ranch are valued at approximately $350,000. Petrified wood is used in lapidary arts and as a component in semi-precious jewelry. Historical royalties and asset sales have exceeded $800,000.

Helium

The Holbrook basin has had significant Helium production at Pinta Dome, and a number of other wells on NZ Lands have had significant shows of Helium mixed with CO2 gases.  NZ has leased these rights to PetroSun, which is attempting to enter the helium production market.

Oil

NZ’s only confirmed oil production occurred at the Nose Rock Oil Pool, discovered in 1986 as a follow-up to a uranium core hole anomaly. Approximately 60,000 barrels of light sweet crude were produced. While additional small pools may exist, most remaining petroleum prospects are considered frontier wildcats, requiring substantial investment and political coordination, especially for areas such as the Acoma Reservation.

Coal

Significant coal seams in McKinley County, New Mexico, were identified as early as 1917. By 1962, estimates based on surface studies reached 160 million tons. Exploration intensified during the 1970s energy crisis, and one 2-million-ton strippable deposit was permitted but never mined. Due to current economics and energy transition trends, large-scale coal development is unlikely.

Potash

NZ’s potash was among the first minerals discovered by drilling. However, global market shifts—particularly the dominance of Saskatchewan’s high-grade potash—have reduced its viability. That said, in a joint venture with Hunt Oil, over $35 million was invested to delineate a NI 43-101 compliant deposit of more than 58 million tons, confirming the strategic value of this asset under the right market or policy conditions.

Kaolin and Industrial Clays (Klannerite)

A localized deposit of altered bedrock, commercially referred to as Klannerite, exists on 80 acres in Mohave County, Arizona. While small in scale and not currently demonstrated to be continuous, it may have niche applications in industrial ceramics or fillers.

Associated Mineral Potential

Geological formations hosting NZ’s known resources may also contain associated or companion minerals, which could be revealed through deeper exploration or re-evaluation. Examples include:

• Uranium zones often contain vanadium, molybdenum, and rare earth elements (REEs)

• Potash-bearing formations may include sylvite, langbeinite, lithium, and magnesium salts

• Travertine and limestone regions may also hold gypsum or high-purity dolomite

• Coal seams can be accompanied by coalbed methane or critical trace elements

• Petrified wood deposits may indicate underlying silica, uranium, or jasper formations

Looking Ahead

While some NZ mineral zones have been intensively studied, vast areas remain underexplored, especially those beneath Indian reservations where title complications have discouraged past investment. With increasing demand for critical minerals, new exploration technologies, and shifting federal policy around tribal land unification and mineral security, NZ’s mineral estate holds both present value and future promise.
