Zone A-5 (S) Au+Cu+Ag pospect

  

   Zone A-5 (S) remains untested along two major faults where the au mineralization is similar to carlin style deposits.  (GM57979)

   Lithology:

    The structurally controlled mineralization consists of a series of quartz-carbonate and radioactive mineral veins within an altered gabbro sill inserted into the sandstones of the Upper Indicator Formation along an ESE axis over a distance of approx. 1 km.

   The mineralization is silicified and rich in sulfides found in shear zones along the sill contact
 zones similar to the Zone L's Au deposit  (further east, on sheet 23D02).

Mineralization:
Mineralization consists primarily of pitchblende in quartz and carbonate veins. 
A large number of minor secondary minerals are also present, including pyrite, 
chalcopyrite, hematite, native copper, bornite, galena, chalcedony, pyrolusite, 
leucoxene, malachite, ankerite, gypsum, and dolomite (GM 57979). 
A zebra-like texture of carbonates is noted cutting the gabbro (GM 65244).

Major structural control:
Feeder dykes cutting the sandstones of the uppermost Indicator Formation and
shear zones along the sill contact zones.

Boréale Exploration (GM57979) conducted a limited resampling of the Cogema's  trenches & 
drill core results as per charts below:
 

trench resampled data

Limited DDH core is resampled 

The GM57979 report concludes:

"only a small proportion of the drilling conducted on the property has been resampled. It is

 therefore encouraged that all available drilling be reexamined and resampled. 

Furthermore, with a view to a Carlin-type context, the Lac Carré and Lac Cigare faults, along

 which the carbonate horizon is offset, remain targets to be tested."

and states:

 "Two hypotheses have been put forward to classify this deposit. 

COGEMA considers that it is a deposit similar to the L zone, consisting of uranium 

mineralization in a lithological and structural trap marked by a particular stratigraphy and 

by the albitization of the gabbro. 

Another hypothesis recently put forward by Boréale Exploration suggests that the mineralization

 is more gold than uranium and that many similarities exist between the model proposed by 

COGEMA and the Carlin-type deposits. 

Gabbro is invoked as a source of heat for the water table and the Péribonca carbonate 

formation would have constituted both a thermal screen and an oxidizing aquifer."
