The November meeting of the BC Geophysical Society will be
Thursday, November 9th. The society plans 4 more meetings
meetings this winter, the second Thursday of November,
January, March and April.
The meetings will be in the Bentall Center conference room -
room 205 Bentall 2 tower 555 Burrard St., Vancouver, BC.
The meeting will start at 4:10 pm. The room is booked from
4:00 to 6:00 for us.
Alain Gachet, whom we have the good luck to catch in
Vancouver on his way to the Erim remote sensing conference
in Las Vegas, will present a talk on the use of radar
imagery to in the exploration of a new discovery in Mali.
His abstract follows, and his bio is attached to this
message.
___________
History of a Gold Discovery in Mali by Radar Imagery
Interpretation
High resolution RADARSAT-1 data with interpretation
conducted by Radar Technologies France in early February
1999 in MALI, revealed a major geological structure within
the middle proterozoic formations, 150 km South West of
BAMAKO. Based upon this radar structural trend, combined
with previous ground sampling, intensive drilling and
TRENCHING program revealed, in August 2000, one year and a
half later, minimum recoverable gold reserves of 29 tons,
with gold content ranging from 10g/ton to 108g/ton and with
local regions (typically 1 meter thick) averaging as high as
2,000g /ton at a depth of 50M. The mineralized lode might
contain more than 100 tons Au according to the continuation
of the structural radar indications.
Initial radar interpretation and field work cost $20,000 US.
Drilling and trenching operations cost $1.5M US. Resulting
NPV (discount 15%) = $73M US after tax.
All the permits near by have been taken one year and a half
ago, according to the radar interpretation, in order to
protect any future discovery.
(First to see, First to decide). Alain Gachet.

Alain Gachet, M.Sc.
After a Master in Nuclear Physics, and a diploma of Mining
Civil Engeener from Ecole des Mines, France, Alain Gachet
has been working for 20 years with the French national oil
company, Elf Aquitaine.
He started his career as Exploration geophysicist, in the
North Sea, where he was awarded a "Technological Innovator"
Prize for successful finding gas traps under salt domes at
3800 m depth, in the Netherlands offshore block L4.
After a distinquished exploration career with successful
projects in Russia, Kazakhstan, Qatar, Syria, Gabon and the
Congo, Alain ended his career in August 1996 as General
Secretary and Economist in Elf Congo, during the civil war.
He then created his own company, Radar Technologies France
(RTF), dedicated to exploration based on a new geophysicist
tool, RADARSAT imagery.
The first radar applications in the rain forest of Congo led
him to discover his first gold targets in 1997. He pursued
his applications for diamond exploration in Sierrea Leone
over kimberlite dykes, and in Mali where he got the first
gold strikes by the end of 1999, in a lateritic context. By
August 2000, his expertise led to an official discovery of
at least 29 tons of recoverable gold reserves, with probable
extra reserves to be expected in near future.
In the meantime, he was invited by the Consortium Agip Exxon
and Elf to run a successful radar mapping program over 8
months in Central Congo, encompassing an oil basin of 150
000 km
�, and by Total Fina to control the environment
evolution of the Maakam delta in Borneo.
Alain has been working in close collaboration with RADARSAT
International to bring his expertise to the international
marketplace.
Anyone visiting Vancouver is welcome to attend.
