  1. Operations Description Climax Molybdenum Company Henderson Operations

  2. Mine Site with Red and Harrison Mountains Harrison Mountain Red Mountain - Mine

  3. Geology • Classic Climax-type porphyry molybdenum deposit • Host rock is granite/aplite porphyry • 474,000 feet of core drilling • Limited accessory mineralization

  4. Preliminary Lab Layout with Drill Hole

  5. Drill Hole in Relation to Proposed UNO Site

  6. Drill Hole into Harrison Mountain • The hole is 2,500 feet in length • The hole had an inclination of -26 degrees with the top at the 7,500 feet and the bottom at 6,300 feet. • The hole was drilled at HQ-3 (2.4 inches in dia.) for 1,397 feet and NQ-3 (1.8 inches in dia.) for 1,102 feet. • Hole deviation was less than 200 feet • Geological logging is complete

  7. Drill Hole into Harrison Mountain (cont.) • The rock is a rhyolite or aplite porphry • The rock is very hard with a high percentage of quartz. • The rock is expected to have a high compressive strength (this will be tested) • The RQD is quite high, 70 – 100. • There is no evidence of mineralization

  8. Drill Hole into Harrison Mountain (cont.) • There were only a few small fractured zones, not near the UNO area, and no fault zones • There is very little water, only about 1.5 gpm. • Due to the hardness and strength, there is some potential for rockbursting when mining. This potential is no greater than what has been experienced at Henderson in the past.

  9. Example of Mineralized Core
