SIGNIFICANT DISCOVERIES

• 1978-79 Mapped the Wyoming portion of the Colorado-Wyoming State Line district & discovered several diamondiferous kimberlite intrusives.
• 1980 Completed mapping & geophysical studies of the Sheep Rock district in the Laramie Range, Wyoming. Discovered the Radichal kimberlite intrusive and numerous 'kimberlitic' heavy mineral anomalies.
• 1981 Discovered significant gold mineralization in the Seminoe Mountains greenstone belt, Wyoming.
• 1982 Discovered significant gold mineralization in the Rattlesnake Hills greenstone belt, Granite Mountains, Wyoming.
• 1983-87 Projects which led to the identification of more than 300 kimberlitic indicator mineral anomalies in southeastern Wyoming.
• 1985-89 Mapped eight 7.5-minute quadrangles of the South Pass greenstone belt & identified dozens of significant gold anomalies and recognized the importance of saddle-reef type gold deposits in an extensive shear zone complex.
• 1988 Identified a potentially major gold deposit at the historical Carissa gold mine that is potentially open-pittable over a width of 1000 feet.
• 1988-89 Mapped significant alteration zones and gold mineralization associated with the Donlin Creek – Snow Gulch disseminated gold deposit, Alaska. This is currently (2003) recognized as the largest undeveloped gold deposit in North America.
• 1990-91 Mapped the Seminoe Mountains greenstone belt & discovered gold, zinc, lead & 'kimberlitic' indicator mineral anomalies.
• 1992-93 Mapped of the Rattlesnake Hills greenstone belt & associated epithermal & exhalitive gold mineralization.
• 1993-94 Mapped the Cooper Hill mining district, Wyoming (1:12,000 scale).
• 1995 Discovered significant Ni and Pd anomaly associated with Cu-Co-Au-Pt-Pd mineralization in the Puzzler Hill layered complex, Wyoming.
• 1995 Discovered a gem-quality sapphire, ruby, kyanite and iolite deposit at Palmer, Canyon, Wyoming. Recovered the largest gem iolite in the world at that time (1,750 carats).
• 1997 Discovered gem-quality peridot in the Leucite Hills, Wyoming.
• 1997-99 Discovered several kimberlites in the Iron Mountain district, Wyoming, and produced a 1:24,000 scale map of the district.
• 2003 Mapped one of the largest opal deposits in North America in central Wyoming.
• 2004 Identified one of the richest iolite-kyanite gemstone deposits in the world at Grizzly Creek, Wyoming. Recovered the largest iolite gem in the world at 24,150 carats.
• 2005 Discovered several anomalies of probably kimberlitic in nature in Wyoming Craton.
• 2006-2008 Organized and formed DiamonEx(USA) Ltd for DiamonEx Ltd & aquired the Sloan Ranch diamond project (Colorado) and found >200 crytovolcanic structures and 8 new districts in Colorado and Wyoming.
