Codihue Sulphur Project

OVERVIEW Biogenic Sulfur Potential
The Codihue biogenic sulfur property, 100%-owned by Marifil Mines, is Several lines of evidence may suggest the exis-
composed of three contiguous exploration concessions that cover a total tence of a concealed biogenic sulfur deposit:
area of 18,000 hectares. It is located in the central part of the Neuquen
province, in the west-central part of Argentina.

evaporates at depth.
The stratigraphy in the project area reflects that of the regional stratigra-
phy because the Neuqen Basin essentially has a laterally continuous
layer-cake stratigraphy over the entire basin. The 200+
meter thick Jurassic Age Auquilco Formation is the formation
of interest on the property. It is comprised primarily of anhy-
drite-gypsum with lesser amounts of limestone and clay.
Regional stratigraphy suggest that the Auquilco Formation
may lie at a depth of 200-400 meters on the Codihue
Property. The stratigraphy of the formation was described
about 30 km away from Codihue at Mallin Quemado.
One example of a biogenic sulfur deposit with similarities to
the Codihue Property is the Mishraq Deposit, located in
northern Iraq. That deposit contains +200 million tons of
native sulfur. It is located in an anticline that is 11 km long by
3.5 km wide. Very tight en echelon folds are superimposed
on the main fold.
There are many fractures and joints which form circulation
channels. Most of the sulfur in the Mishraq Deposit is host-
ed by the Lower Fars Formation. The productive stratigraphy
is composed of a fine-grained carbonate and secondary
coarse-grained calcite and sulfur with anhydrite-gypsum.
The thickness of the sulfur-bearing stratigraphy varies from
40 to 140 meters. The ore zones in the productive member
are highly re-crystallized biogenic calcite and finely crystal-
lized native sulfur. The thickness of the mineralized zone
increases in fold hinges. The ore body covers approximate-
ly 10 km2. The average sulfur content is 23.14% (ranging
between 25.5% and 19.8%). The thickness of the ore body
varies from 2 to 124 meters with a variable depth of 73 to
303 meters. The porosity of the body varies between 3 to
13%.
