CH Project Area

Project Status

(Map showing where Courageous is on CH.)

  • 12 potential kimberlite targets have been identified on these claims.
  • Two targets were drill tested in 2006 and one proved to be a diamondiferous kimberlite pipe subsequently named the “Bishop” kimberlite.  The “Bishop” is located 40 km south of the Ekati Diamond Mine.
  • 18 claims comprising the Courageous Property were staked in 2000.
  • History: Most of this ground was originally staked by Diamondex (formerly Winspear) in 1992.  A limited amount of sampling (55 samples), geophysics (200m line spacing Dighem Mag/EM), and drilling (3 holes) was conducted.  The northern row of claims was staked by Kennecott in 1994 and their exploration work included the collection of 51 samples and airborne geophysics (150m line spacing Dighem Mag/EM).
  • Exploration activities since 2000 have included extensive indicator mineral sampling, airborne magnetic and EM surveys, and drilling (4 targets in 2002).
  • In 2006, a total of five gravity surveys over five targets, including the Bishop area, and 94 heavy mineral samples and 94 soil samples were collected.
  • An Option Agreement with Kennecott Canada Exploration Inc. grants Kennecott the right and option to acquire, subject to Royalties, a 100% interest in the Property, by incurring expenditures of $10,000,000 on or before December 31, 2016.

(Small map showing where Mackay is on CH)

  • Four claims comprising the MacKay Property were acquired in 2001, based on isolated and elevated kimberlitic indicator results identified from the GGL database.
  • History: Claims were originally staked by Geomaque in 1992 and optioned to Kennecott. Exploration conducted on these claims included the collection of 16 samples and conduction airborne geophysical surveys (200m line spacing Geoterrex Time Domain EM).
  • Sampling has confirmed previous results and defined a kimberlitic indicator train.  A detailed magnetic/electromagnetic (50 m line spacing Dighem Mag/EM) was flown in 2001.
  • One target was drilled in 2001 for a total of 327 metres within the main area of interest.  The source of the indicator minerals was not found and further drilling is required.

G-claims (Big Red)

(Small map showing where G-Claims are on CH)

  • Areas with kimberlite potential were identified from the GGL database and the G-Claims were staked in early 2000, within one kilometre of De Beers "Big Blue" kimberlite, which was discovered in 2001.
  • Lake-based ground geophysics, undertaken in 2001, discovered a coincident EM/magnetic/bathymetric response, considered indicative of kimberlite.
  • A Dighem survey in early 2002 confirmed an anomalous geophysical response.
  • A June 2002 lake sediment analysis identified samples within the bathymetric low containing elements known to be found in kimberlites.
  • Two EM geophysical targets – including “Big Red”- have been identified as drill targets. One drill hole was completed on the "Big Red" target. 

(Small map showing where Seahorse/Shoe are on CH)

  • 29 claims comprising the adjoining Seahorse and Shoe Properties were acquired between 2000-2002.  Containing a total of 117,084 acres, these properties are centred approximately 35 km southeast of the Ekati Diamond Mine.
  • Staking was based on anomalous kimberlite indicator distributions and geophysical data compiled in the GGL database.
  • History: De Beers held most of this ground from 1991 and conducted 250 metre line spaced airborne Magnetic and Time Domain EM Geoterrex geophysical surveys.  Kennecott held part of the area in 1994 and gradually let claims lapse.  Kennecott conducted sampling and geophysics programs (150m line spacing Dighem Mag/EM).  The northern four Shoe claims were owned by DHK between 1992 and 2002 and were optioned to several companies including Kennecott and BHP.
  • Exploration work by GGL since 2000 has included indicator mineral sampling and detailed airborne magnetic/EM surveying.
  • Identified as isolated magnetic high responses, three kimberlites -- Rainier, Adams and Shasta -- were discovered in the southeastern portion of the property in 2002.  No diamonds were recovered from these kimberlites.
  • A number of drill targets have been identified on these claims.
  • The largest and most attractive target is on the Shoe claims, 27 km southwest of Ekati’s Fox kimberlite pipe, which was recently placed into production.  The Shoe target, up to 300 m in diameter (nine hectares) is located in a lake and is defined by an airborne gravity anomaly flown by the BHP Condor system.
  • A second drill target on the shore of the same lake is a magnetic anomaly 200 m x 100 m defined by a Fugro airborne geophysical survey conducted for the company.  The targets are at the head of a kimberlite indicator mineral train and are highly prospective to host a diamondiferous kimberlite.
  • Two other geophysical targets, supported by mineral sample results, have been identified on the same mineral claim
  • Approximately $500,000 would be required to complete ground geophysical surveys and drill up to four holes on these targets.

(Small map showing where Starfish is on CH)

  • 29 claims acquired between 2000-2003.
  • History: De Beers held this ground from 1991 to 1994 and conducted 250-metre line spacing Geoterrex Mag/Time Domain EM airborne geophysical survey.  Kennecott restaked the area in 1994 and gradually let claims lapse. Kennecott collected 638 samples and conducted a 150 metre line-spaced Dighem Mag/EM airborne geophysical survey.
  • Sampling by GGL between 2000 and 2001 confirmed areas anomalous in kimberlite indicator minerals and projected these counts to the northwest section of the claims.  A detailed (50 metre line spacing) airborne Fugro Mag/Electromagnetic survey was flown in 2003 and kimberlitic targets have been ground checked.
  • During the 2004 spring exploration program, ground geophysics was conducted over eight isolated geophysical targets.
  • One target was drilled in 2005; no kimberlite was located.
