The Search for Gold, Silver, Platinum Groups & Gemstones


Geological Consultant

My specialty is finding gold, base metal, diamond and/or colored gemstone deposits, prospects & anomalies. A chronology of discoveries & achievements include:

  • 1978-79 Mapped Wyoming portion of Colorado-Wyoming State Line district: discovered several diamondiferous kimberlites (Hausel and others, 1979, 1981).
  • 1980 - Completed geological map of Sheep Rock kimberlite district. Discovered Radichal kimberlite & strong kimberitic heavy mineral anomalies indicating presence of hidden kimberlites (Hausel and others, 1981). Area remains unexplored.

  • 1981- Discovered significant gold mineralization in Seminoe Mountains greenstone belt: led to gold-rush. Visible gold was recovered in >a dozen samples. Several anomalies included gold in propylitically altered greenstones & banded iron formation. Assays  from a trace to 2.87 opt Au (Hausel, 1993, 1994).
  • 1981-1982 - Discovered the Rattlesnake Hills gold district. Identified significant gold in Archean pyritiferous veins, exhalites, stockworks, banded iron formation & Tertiary breccias associated with alkalic plugs (Hausel, 1994, 1995) based on favorable geology (Hausel, 1980, 1989) & verified by follow-up reconnaissance (Hausel and Jones, 1982a,b) & mapping (Hausel, 1995, 1996). Company drilling verified presence of significant subsurface gold. 

  • 1982 - Mapped hydrothermally altered (propylitic & potassic) zones at Copper King Mine in Silver Crown district. Proposed property to represent large-tonnage, low-grade Au-Cu porphyry. Years later, company drilling identified a Au-Cu resource equivalent to >1 million ounces of Au (Hausel & Jones, 1982b; Hausel, 1997).

  • 1983-87 Identified >300 kimberlitic indicator mineral anomalies in southeastern Wyoming & Grant Creek kimberlite. Some anomalies were later tested: majority of sites yielded diamond-stability kimberlitic indicator minerals (Hausel and others, 1988; Hausel and others, 2003).
  • 1985-89 Mapped eight 7.5-minute quadrangles in South Pass greenstone belt & identified >100 Au anomalies. Recognized saddle-reef control of Au deposits in extensive shear zone complex (Hausel, 1991).
  • 1988 Discovered significant Au at Purgatory Gulch, Sierra Madre. Samples contained visible Au (Hausel, 1997).

  • 1988 Identified major gold deposit at Carissa gold mine. An ore shoot, 1000 by 980 ft on the surface continues to a minimum depth of 930 ft based on company drilling. Target is open at depth (Hausel, 1999, 2009). Likely hosts several million ounces.
  • 1988-89 Mapped significant alteration & mineralization associated with Donlin Creek (Snow Gulch-Ruby Gulch-Lewis Gulch-Queen Creek) disseminated Au deposit, Alaska: nearly a 10 mile strike length. In 2003, this was described by Northern Miner as the largest undeveloped gold deposit in North America. More recently Northern Miner reported this as one of the largest untapped gold deposits in the world based on a drilled resource of >29.3 million ounces & inferred resource of 10 million ounces. The size of the deposit (39.5 million ounces rivals the Homestake (produced 41 million ounces over 100 years) & is essentially equivalent to all gold produced in Alaska in the 19th and 20th centuries! Seven geologists (including Hausel) were presented the Thayer Lindsley Award for significant International Mineral Discovery at PDAC (2009) in Canada for this discovery.
  • 1990- Found high grade Au and Ag mineralization (>1 opt) at Mineral Hill. One channel sample yielded >4 opt Au and >10.5 opt Ag (Hausel, 1997).

  • 1990- Found the first verified amethyst in Wyoming at Artic Mine, Mineral Hill.

  • 1990-91 Mapped Seminoe Mountains greenstone belt: discovered Au, Zn, Pb & 'kimberlitic' diamond-stability indicator mineral anomalies (Hausel, 1993, 1994).

  • 1991 - Investigated large gold paleoplacer & discovered diamond indicator minerals on north flank of the Seminoe Mountains (all tested were diamond-stability (G10) pyropes!).
  • 1991 - Published book on South Pass Gold and Geology.
  • 1991-93 Discovered large, significant gold-rich zone at Copper Creek, Sierra Madre! (Hausel, 1997).

  • 1992-93 Mapped Rattlesnake Hills greenstone belt & associated epithermal & exhalitive Au mineralization (Hausel, 1995, 1996).

  • 1993-94 Mapped Cooper Hill mining district, Wyoming (1:12,000 scale).

  • 1995 Discovered significant Ni and Pd anomaly associated with Cu-Co-Au-Pt-Pd mineralization at Puzzler Hill pyroxenite massif (Hausel, 1995, 1997).
  • 1996 Discovered gem-quality sapphire, ruby, kyanite & iolite at Palmer Canyon, Wyoming. Recovered largest iolite gem in world (1,750 carats) at that time(Hausel, 1998).

  • 1996- Recovered large rubies in Tin Cup district at Red Dwarf ruby deposit (Hausel, 1997). Developed exploration model for rubies & sapphires that led to discovery of nearly a dozen ruby-sapphire deposits (Hausel, 2003; Hausel and Sutherland, 2000, 2006).
  • 1997 - Published book on Copper.

  • 1997 - Discovered gem-quality peridot in Leucite Hills. Recovered >13,000 carats from two anthills & gems 0.5 inch across in outcrop & soil (Hausel, 1998, 2004).

  • 2004 - Identified one of the largest colored gemstone deposits in world at Grizzly Creek with the largest iolite gemstones on earth along with significant resource of gem kyanite. Recovered largest iolite gem in the world (24,150 carats). Some in outcrop estimated to weigh >100,000 carats (Hausel, 2004). Predicted deposit based on geology (Hausel and Sutherland, 2000).

  • 2005 - Discovered potentially the largest colored gemstone deposit on earth in Sherman Mountains. This world-class iolite deposit may have >2 trillion carats of gemstones based on past mapping & sampling (Hausel, 2005).  WGS director confiscated field vehicle to stop research.

  • 2005 - Discovered several crytovolcanic structures (kimberlite-like anomalies) in Wyoming Craton (Happy Jack, Horse Creek, Eagle Rock clusters).

  • 2005 Mapped Leucite Hills lamproite field & identified diamond-stability indicator minerals in NE portion of the field - recommended exploration for hidden olivine lamproites (Hausel, 2006).

  • 2006-2008 Discovered cryptovolcanic structures with characteristics consistant of kimberlite (i.e., structurally-controlled depressions with vegetation anomalies, montmorillonite-carbonate blue ground). These include Harrison, Lost Mountain, Twin Mountain, Lost Lake, Lone Pine Lake, Molly, CML, BG, BA, WPA, Gold Lake, Prairie Divide, Lady Moon Lake, Red Feather Lakes & Douglas Creek clusters.

  • 1977-2011. Identified hundreds of gold anomalies.
  • 1977-2012 Discovered dozens of colored gemstone & diamond deposits, prospects & anomalies.
  • While employed by the Wyoming Geological Survey for 29 years, I conducted field projects on my own initiative and mapped several Archean and Proterozoic belts along with Tertiary volcanic terrains and several generations of kimberlite, lamproite and lamprophyre.  Much of what is currently known in Wyoming about hard rock mining districts and Archean geology is due to my research.

    I was awarded the Wyoming Geological Association's highest award for these contributions in 2004 - the only geologist from the Wyoming Geological Survey to ever receive this honor (the WGA is a society of professional geologists).

    I discovered the Rattlesnake Hills gold district in 1981 while exploring this greenstone belt that had been intruded by more than 42 Tertiary alkalic plugs and dikes. To me, this was an obvious gold target for exhalite, replacement deposits, breccias and stockworks that had been overlooked by all others. This area is now being compared to Cripple Creek.

    While at the WGS, I mapped and explored more than 3 dozen underground mines (scale 1:120 or 1:240), mapped the Lewiston, South Pass-Atlantic City, Miners Delight, Bradley Peak, Silver Crown, Cooper Hill, Copper Mountain, State Line, Iron Mountain, Leucite Hills, Middle Sybille Creek districts and mapped the South Pass, Rattlesnake Hills and Seminoe Mountains greenstone belts at 1:24,000 scale. In total, I produced more than 1,000 square kilometers of new geological mapping.

    Winters were long in Wyoming, so I wrote while the snow fell and temperatures often dipped to 50 below. When I could get out of town, I traveled the country giving lectures on geology and prospecting and I was presented the 1992 AAPG's President's Certificate, the 1994 Laramie Lyceum's Distinguished Speaker Award, and 1998 University of Wyoming Department of Geology and Geophysics Distinguished Lecturer. I was the only member in the history of the Wyoming Geological Survey to be inducted into a Hall-of-Fame for my work: the 2001 National Rock Hound & Hall-of-Fame & was presented the Education Award. I was inducted into the Millennium Hall-of-Fame in 1998 and nominated for two others for my geological contributions & contributions as a polymath.

    I published more than 1000 books, maps, general interest, professional papers and abstracts and consulted for several mining companies. I was on the discovery team of Donlin Creek gold deposit in Alaska. This 41 million ounce deposit was discovered by 7 geologists (including myself) in 1988 and 1989. In these summers, I took leave from the WGS to consult for WestGold. In 2009, myself and 6 other geologists were awarded the Thayer Lindsley Award by the PDAC in Canada for this great discovery.

    Along the way, I consulted for several companies on gold, base metal and gemstone deposits. Some companies I consulted for include Chevron Resources, Echo Bay, Bald Mountain, DiamonEx, Black Range, Western Archon, Endurance Gold, Fowler Resources, MK Gold, Twin Buttes, Teras Gold, Ice Resources, Sachem Prospects, Giant King Gold, Saratoga Gold and others.

    I planned and conducted geophysical surveys in the search for kimberlite including EM, resistivity, gravity and seismics including a number of remote sensing studies. I also interpreted data from INPUT geophysics to find diamond deposits.

    Imagine a mining company finding two of the largest gold deposits in North America, two of the largest colored gemstone deposits on earth, dozens of diamond deposits, nickel-palladium-copper-gold, hundreds of gold anomalies, several dozen colored gemstone  deposits, mapping >1000 square kilometers of mostly unmapped terrain, publishing nearly 1000 papers, books, maps and abstracts. Is this company Anaconda Mining? Homestake Mining? DeBeers? Nope, just a geologist who is very curious about the world.

     One deposit, I discovered with a group of geologists, now has a drilled resource of about $65 billion in gold. Another is being compared to the famous Cripple Creek, Colorado gold deposits and lies within an extensive gold district. One discovery has gems nearly as large as a small pickup truck (at $15 to $150/carat), and another deposit could have 2 trillion carats of colored gemstones.  Along with these I recovered the two largest iolite gemstones in the world - one weighed 1,750 carats, or just a little more than half the size of the famous Cullinun diamond, and the other weighed 24,150 carats. I also found more than 2 dozen diamondiferous kimberlites and hundreds of cryptovolcanic structures.
