The Cortez Canyon Mine Guide
A privately held Nevada turquoise deposit known for its rare mint to lime green spectrum and iron‑rich matrix.
A Rare Nevada Turquoise Deposit
Cortez Canyon Mint is a small, privately managed turquoise deposit located in the high desert of Nevada. The claim sits within a mineralized corridor known for producing some of the most distinctive green and mint‑toned turquoise in the American West. Because the terrain is remote and the site is not yet secured, the exact location is intentionally kept confidential to protect the land, ensure responsible stewardship, and maintain the integrity of the material.
Collectors and lapidary artists value Cortez Canyon Mint for its mint‑green palette, iron‑rich matrix, and limited production, making each piece a genuine representation of Nevada’s turquoise heritage.
Geological Formation
Turquoise forms through a slow, delicate process: copper minerals, iron, aluminum, and water interact over long periods within host rock. Cortez Canyon turquoise developed in a zone where:
Copper mineralization is strong enough to produce vivid greens
Iron content influences matrix color and pattern
Hydration levels create the signature mint‑to‑canyon‑green spectrum
Host rock fractures allow turquoise to fill seams, veins, and pockets
This combination produces material that is both visually striking and structurally stable for cutting.
The deposit’s geology places Cortez Canyon in the same broad mineral trend as several historic Nevada turquoise sources, though its color profile and matrix behavior are uniquely its own.
Color Profile & Visual Characteristics
Cortez Canyon turquoise is known for a color range that moves through:
Pale mint green
Soft lime tones
Canyon green with subtle yellow undertones
Occasional blue‑green transitions in hydrated pockets
Matrix patterns vary from:
Fine iron webbing
Open fracture lines
Plume‑like iron inclusions
Soft, sandy host‑rock matrix
History of the Claim
The Cortez Canyon turquoise deposit traces its heritage to one of Nevada’s most iconic turquoise figures: Orvil Jack. In the mid‑20th century, Orvil became known for uncovering pockets of vivid green turquoise in central Nevada — material so distinctive that collectors still recognize “Orvil Jack green” as its own category. His finds were small, scattered, and often difficult to access, but they revealed a rare mineral signature: copper‑rich turquoise influenced by iron, producing luminous greens instead of the more common Nevada blues.
Cortez Canyon Mint comes from extensions of the same mineralized system that Orvil originally worked. These are not recreations, imitations, or reinterpretations — they are geological continuations of the same turquoise‑bearing trend he first identified. The deposit sits within the broader corridor where Orvil Jack made his historic discoveries, following the same host rock, the same mineral chemistry, and the same iron‑influenced color spectrum.
Because the terrain is remote and the site is not secured, the exact location of the Cortez Canyon claim remains private. This protects the land, preserves the integrity of the deposit, and honors the tradition of small, responsibly managed turquoise claims — the same approach Orvil himself practiced.
Today, Cortez Canyon Gems continues that lineage by stewarding the deposit with care, documenting each piece, and bringing forward new material that reflects the unmistakable character of Orvil Jack’s original green turquoise. Every slab and stone carries that history: a modern chapter in a story that began decades ago with Orvil’s remarkable eye for Nevada’s rarest greens.
Mining & Extraction Process
Mining at the Cortez Canyon deposit is done through a small, controlled operation using both heavy machinery and careful hand‑work. Excavators are used to safely bring down high walls and open access to the turquoise‑bearing zones. Once the larger rock faces are cleared, the team switches to more selective methods to recover the turquoise itself, preserving the natural veins and minimizing damage to the material.
This balanced approach allows the deposit to be worked safely, responsibly, and with respect for the land, while ensuring that each piece of Cortez Canyon turquoise reflects the quality and character of the original formation.
How Cortez Canyon Turquoise Compares to Other Nevada Turquoise
Nevada is home to many iconic turquoise mines. Cortez Canyon stands out for its mint‑green spectrum, which differs from:
Royston — typically deeper greens and blues with bold matrix
Pilot Mountain — known for blue‑to‑green transitions and dramatic webbing
Number 8 — famous for tight golden webbing and sky‑blue tones
Carico Lake — apple‑green hues with black or brown matrix
Candelaria — high‑grade blues with tight webbing
Cortez Canyon’s color sits in a rare niche: soft mint greens with iron‑influenced matrix, making it especially appealing to lapidary artists seeking unique material.
Collector Notes & Buying Tips
Collectors and cutters appreciate Cortez Canyon for:
Stability — it takes a polish well and resists fracturing
Color rarity — mint‑green turquoise is uncommon in modern production
Matrix variety — each piece has its own personality
Provenance — limited‑production mines create long‑term value
When evaluating pieces:
Look for consistent color saturation
Examine matrix patterns for aesthetic appeal
Check for natural fractures and how they affect cutting plans
Review provenance information to ensure authenticity

Frequently Asked Questions
Where is the mine located?
Nevada. The exact location is private for safety and land protection.
Is Cortez Canyon natural or stabilized?
All material is sold as natural, never stabilized.
Why is the turquoise green instead of blue?
Higher iron content and specific hydration conditions create the mint‑green spectrum.
How rare is this deposit?
Very. Production is limited, and the deposit is small compared to historic Nevada mines.
Can I visit the mine?
No — the site is not secured or accessible to the public.
