This is a classic sandstone-hosted uranium ore specimen collected from the Hideout Mine, Utah, a well-documented Colorado Plateau uranium locality.
The specimen displays yellow-green secondary uranium mineralization distributed through a tan to brown sandstone matrix. Under magnification, the host rock shows pink iron-stained quartz and feldspathic sand grains, typical of uranium-bearing sandstones from the region. These pink grains are part of the host rock and are not radioactive.
Radioactivity is associated with the yellow uranium mineralization and darker matrix, producing a solid ~20,000 CPM reading despite the specimen’s thin profile.
This piece represents authentic ore-grade uranium mineralization and is well suited for collectors who want a representative Colorado Plateau uranium specimen with clear geology and measurable activity.
• Weight: 2 oz
• Dimensions: approx. 2.5 × 2.5 × 0.25 inches
• Locality: Hideout Mine, Utah, USA
• Condition: Natural, unprocessed, no stabilization or enhancement
• Measured Activity: ~20,000 CPM
• Instrument: Pancake Geiger probe
• UV Response: No significant fluorescence observed
• Shipping: Ships legally under UN 2910 – Excepted Radioactive Material
⚠️ Radiation Notice:
This specimen emits measurable ionizing radiation. Avoid prolonged handling and display appropriately.
• Classic Colorado Plateau sandstone-hosted uranium
• Pink quartz / feldspar grains are host rock, not uranium minerals
• Moderate-to-strong activity relative to size
• Excellent educational and comparison specimen
• Good mid-tier piece between low-CPM ore and ultra-high-activity specimens
