Segala Ouest

Technical Report

Desert Gold’s Segala Ouest permit is sandwiched between Randgold’s Loulou Mine permit in the west and Avion’s Segala Mine permit in the east. The permit is underlain by metasediments, metavolcanics and granites of the Kenieba inlier. Artisinal gold mining occurs in two localities on the permit. Mining on the Segala Mine trend extends into the Segala Ouest permit where miners mine on a 450m long zone.  Drilling and trenching on the permit indicates that gold mineralization exists in the bedrock.

The following elements upgrade the exploration potential of Segala Ouest:

  • Suitable rock types - underlain by Birimien meta-sediments, volcanics and granitoids
  • Within Western Mali Gold Belt
  • Adjacent to producing mines including:
    • Loulo 11.5Moz resource ( Randgold )
    • Segala and Tabakoto 3.3Moz resource ( Avion )
    • Gounkoto 8.33Moz resource
  • Mineralized trend from Segala Mine extending onto the permit.
  • Gold production from artisanal mining
  • Gold mineralization intersected in boreholes and exposed in trenches
  • Gold mineralization intersected in boreholes coincide with geophysical targets
  • Known drilled gold deposits with mineralization open down dip
  • Targets defined for follow-up

The Djimbala Permit was recently obtained by Desert Gold. Desktop studies from available information revealed five prelimaniry targets for follow-up.

Exploration work undertaken on Segala-Ouest comprises

  • Soil geochemical surveys – 2982 samples assayed
  • Trenching – 11 trenches excavated
  • Ground magnetic survey
  • IP/Resistivity survey
  • Auger sampling – 248 samples
  • Reverse circulation drilling – 60 holes and 5820m
  • Diamond drilling – 12 holes and 2390m

Eleven trenches were dug or reopened over soil anomalies on the two permits totalling 1,630m in length and yielding 1,806 samples. Results from channel sampling in the trenches include:

  • 1m @ 2.97g/t Au
  • 15m @ 0.86g/t Au
  • 8m @ 1.68g/t Au
  • 1m @ 3.12g/t Au
  • 3m @ 1.37g/t Au
  • 10m @ 2.87gt Au

An RC drilling program was initiated in March 2009 by Desert Gold was completed during May 2009.  Sixty (60) drillholes, totalling 5,820m, were completed.  Drillholes were drilled to test soil anomalies.

Significant intercepts (sample drillhole length not true width) include:

Initial integration of the soil, RC, magnetic and IP data revealed a number of exploration targets that were to be investigated through diamond drilling.  Four drillholes were drilled to investigate the granite – greenstone contact.  The diamond drilling program included some 12 drillholes for a total of 2,404m. 

The following intersections were made in the diamond drillholes (widths are drillhole lengths and not true widths):

Artisinal mining on Segala Ouest

In 1995, BHP Minerals carried out soil sampling surveys over parts of Segala-Ouest and identified two soil anomalies.  No further work was undertaken. From 1996 through early 1998, two junior companies Alpine Exploration Corporation and ResourcesRobex Inc. (Vancouver SE and Montreal SE listed companies), completed geological mapping, soil sampling and an induced polarization survey over part of the Segala-Ouest permit area known as the Baroya concession, essentially the current Segala-Ouest permit area.  Two of 10 planned diamond drillholes were completed.  The program was not continued following the rainy season because of poor financial markets for gold companies and negative results from the initial two drillholes.  Great Quest Metals Ltd had rights to the Segala-Ouest permit through 2007 and carried out exploration activities on part of Segala-Ouest in 2003.  Except for three drillholes drilled, little work appears to have been carried out on the permit.
