Geology:
Gray sandstone, medium to fine grain, 98% purity.
Results:
RESERVES: estimate based on 500 m of length by 500 meter
width, by 50 m thickness and density of 2.6 = 32,500,000
metric tons Probable and possible reserves may reach 50,000,000
tons.

km toward the
SE of Guayzimi.

Introduction:
An in situ inspection of the Fadgoy mining area was made
September 5-6, 2000 by Ing. Darwin Suri and Geologist Michel
Rowland to
report on the silica exploitation in said area.
Location:
Fadgoy mining area is located 2 Km southeast from the village of
Pachicutza, 15 Km toward the southeast of Guayzimi. UTM
Coordinates from
the departing point are X=763000 Y=9541300 Z=920.
Access:
From Loja to Pachicutza, four and an half hours, the Loja-Zamora
leg
is paved. Between Zamora and Zumbi is a second grade CARRETERO
LASTRADO. Between Zumbi-Paquisha leg is awful. Last leg is
acceptable.
From
Pachicutza to the silica deposit there is a 5 meter wide 5 Km
long pilot
road built by TVX Mining. UNKNOWN WORDS" EMPALIZAR
LASTRAR. 4M3 trucks can go through with no problem but to the
stretch leading tot he mine,
which is not ready.
Weather.
Humid, warm temperatures from 20º y 30º. Rain: 3000 mm
a year.
Reserves
are estimated in 500 m of length by 500 meter width, by 50 m
thickness. With a density of 2.6 this means 32.500.000 metric
tons. Probable and possible reserves may reach the 50,000,000
tons.
Works
needed: Dig trenches of an orientation of N-40-F 50 meters long
from
the existing road to define the thickness of the cover and
verify the quality
of the sandstone.
Get
representative samples for granulometry, impurities and other
attached minerals and give them out among potential buyers as
marketing tactics.
Conclusions
and recommendations:
It is an excellent-quality gray sandstone, medium to fine
grain, good for the multiple uses already indicated. The
existence of an access road to the mine
is a plus for the realization of such a project. The ease for
exploitation will reduce the operational cost to a maximum.
The
only negative factor is the considerable distance from the
market. Transportation cost will increase the final price. I
would suggest to shop
for stockholders among buyers of the raw material.
