  • 1978-79 Mapped the Wyoming portion of the Colorado-Wyoming State Line district & discovered several diamondiferous kimberlite intrusives.

Diopside megacryst


  • 1980 Mapped the Copper Mountain supracrustal belt.
  • 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. This area has some potential for open pittable gold but remains unexplored.  Investigated a major paleoplacer with gold and nothing but G10 diamond stability garnets from an unknown location.
  • 1981-82 discovered significant gold mineralization in the Rattlesnake Hills greenstone belt, Granite Mountains, Wyoming. This was a district has been completely overlooked by all others. He discovered exhalitive gold, gold in BIF, gold in strockworks, in veins, & Tertiary alkalics intrucding the greenstone belt and in metagraywacke breccias.  One company has now identified more than 1 million onnces at one of these. 
  • 1983-87 Managed projects which led to the identification of more than 300 kimberlitic indicator mineral anomalies in southeastern Wyoming. Evidence supports hundreds of undiscovered diamond deposits in Wyoming, Colorado and Montana.
  • 1985-89 Mapped the South Pass Greenstone Belt. Mapped eight 7.5-minute quadrangles of the South Pass greenstone belt & discovered several hundred gold anomalies & previously reported BIF (banded Iron Formation).  The belt covered more than 650 km2 of surface area. He was able to map, differentiate all of the mappable units & structure, & discovered the contolling factors for gold deposits. Based on this latter, there are several commercial gold deposits in this district. Past researchers & prospectors all made classical interpretations that were probably incorrect. At one deposit in particiular - the Carissa mine, he identified a major gold deposit that has excellent drill intersepts, but remains open in every direction.  This deposit is highly mineralized over a 750 ft strike length, more than 1000 feet wide and continuoous to at least 970 feet at a minimum!



Gold at the Duncan Mine, South Pass: >100 significant

gold anomalies were found & structural controls

for gold were identified during mapping.

This study predicted the presence of major gold deposits

at the Carissa, Dickie Springs & Roundtop Mountain.

Significant gold deposits were also found at the Diana,

Tabor Grand, Wolf & other properties.


  • 1988 Discovered siginificant gold mineralization at Purgatory Gulch, Sierra Madre, Wyoming.
    1988-89 A member of the discovery team of the Donlin Creek epithermal gold deposit, Kuskokwim Alaska. The discovery team included Mark Bonston, Richard Garnett, Paul Graff, Tony Hindermann, Bruce Hickok, Rob Retherford & Dan Hausel.  Mapped significant alteration zones and gold mineralization associated with the Donlin Creek – Snow Gulch disseminated gold deposit, Alaska. This was (2003) recognized as the largest undeveloped gold deposit in North America and later identified as one of the largest gold deposits in the world with 39.5 million ounces of identified and inferred resources.
  • 1980s and 1990s, discovered dozens of agate, jasper and onyx deposits in Wyoming. Many of these were listed in the book on Gemstones of Wyoming (WSGS Bulletin 71) published in 2000. The discoveries included the source of the Sweetwater agates at Cedar Ridge, Jasper in the Tin Cup district, jasper in the Rattlesnake Hills and several other deposits.

This was one of dozens of agate, jasper and onyx discoveries recently made in this area that

was a former gold mining scam in the late 1800s and early 1900s. Similar scams were investigated by the author

that included Pine Mountain near Casper where 287 million ounces of gold was allegially found (although no gold was present),

at French Creek where assays were reported in the hundreds of ounces per ton, and later another scam indicated the discovery of the largest

palladium-platinum deposit in the world. A scam in California was reported to have more gold and platinum

than had been mined in all of human history. I was also lucky enough to investigate the historical 'Great Diamond

Hoax of 1872 near the Wyoming-Colorado border (right next to a bonafide diamond district).


  • 1990 Discovered significant gold and silver mineralization at Mineral Hill, Wyoming.
  • 1990-91 Mapped the Seminoe Mountains greenstone belt. Discovered gold, zinc & lead mineralization as well as a large gold- and possibly diamond- paleoplacer along the edge of the Seminoe Mountains. A strong 'kimberlitic' indicator mineral anomaly found near the Miracle Mile suggests the presence of an undiscovered rich diamond deposit in that area.
  • 1991-93 Discovered very significant gold & silver mineralization at Copper Creek, Sierra Madre.
  • 1992-93 Mapped of the Rattlesnake Hills greenstone belt. Also found associated epithermal & exhalitive gold mineralization.
  • 1993-94 Mapped the Cooper Hill mining district, Wyoming (1:12,000 scale).
  • 1995 Discovered significant Ni & 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 & 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 as well as evidence for diamondiferous lamproites.


One of the 13,000 carats of gem-quality peridot

discovered by me during exploration of the Leucite Hills in southwestern

Wyoming. During research in this area for diamonds, these gems were found

as well as evidence for hidden diamondiferous lamproites similar to the Ellendale field in Australia.

Olivine increases in quantity to the northeast, and diamond-stability

chromites were recovered from two lamproites in the northeastern portion of this field.


  • 1997-99 Mapped the Iron Mountain kimberlite district. Discovered several dozen kimberlites in the Iron Mountain district, Wyoming. This work also led to the discovery of the Indian guide cryptovolcanic anomalies to the west of Iron Mountain that are probable unexplored kimberlites.
  • 2003 Mapped one of the largest opal deposits in North America in central Wyoming, and discovered mountains of common opal, considerable fire opal, and some precious opal along with valuable decorative stone and the source are for the Sweetwater agates.


Opal from Cedar Ridge discovery. Common, fire and precious opal

were found over 16-square miles south of Riverton, 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. Some gemstones remaiin in place that may weigh more than a tonne! This is a world-class deposit with know known equivalent on Earth.

iolite gemstone. Much of the outcrop shown in this photo

 is massive iolite. Fresh surface shows the beautiful, blue, transparent gemstone.


  • 2005 Recognized gem-quality iolite in southern Wyoming. This potentially represents one fo the largest (if not the largest) gemstone deposits in the world and could potentially have a resource of 2.4 trillion carats! However, much field work will be required to prove this deposit.

These include pink sapphires, a blue sapphire, and some iolites.

Other discoveries of similar gemstones included some of the

largest gemstones ever found on earth - such as a massive ioite

gemstone larger than a door, and another iolite deposit that is essentially

unexplored by could host several hundred billion carats of the gemstone.


  • 2005 Discovered some kimberlites in the Laramie Range in a previously unknown district
  • 2006-07 As consultant for Teras gold, he recommended four marjor gold deposits - two in Wyoming, one in Utah & the latter in Arizona. All are potential major gold deposits, a few are probably world class.
  • 2006-08 - While VP  of Exploration for DiamonEx  LTD, I put together a US  diamond exploraton company, recommmended the Sloan ranch kimberlites (which could host 33,000 to more than 330,000 in diamond resources, tried to tied up the Kelsey Lake mine, and identiied more than 200 very high-quality targets (cryptovolcanic anomalies with many characteristics of kimberlite). 







The above photo cluster shows a variety of pyrope, almandine-pyrope, chromian diopside and chromian enstatite collected from anthills, outcrops

of the Bishop conglomerate, and also from the Cedar Mountain diamondiferous lamprophyres in the southern Green River Basin, Wyoming. The faceted gems

were cut in Sri Lanka and yielded extraordinary 'Cape Rubies' and 'Cape Emeralds'.
