The Henderson mine is a large scale commercial Molybdenum mine on the east slope of the Continental Divide in Colorado. Despite the large amount of mining that takes place underground, there are very few specimens from this mine on the market. The mine is still operating today (2009), but it remains one of the few active mines in Colorado, which is sad as there were well over 100 operating mines in Colorado over 30 years ago. This mine is known for its Rhodochrosite specimens, despite the fact that they are rarely seen on the market these days. This comprises a few sharp, bladed, pale pink color blades of Rhodochrosite with minor Pyrite. This piece was mined approximately 30 years ago, and was one of the few Rhodochrosites from the Henderson in the Colorado collection of Rich Kosnar. From the 257-708 Area, 8100 Level.
