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."

Lac Connelly adv. Fe (DSO) deposit

  

he 2011 exploration program consisted of prospecting and rock sampling to confirm the presence of hematite bearing horizons to the north of Lac Connelly. 

The first hematite bearing horizon was traced for 2.5 kilometres along a northeast strike, with a minimum width of 30 metres. 

The second hematite bearing zone is located 1.5 kilometres to the northwest of the first horizon and was traced for 1.2 kilometres along a northeast strike, and based on preliminary mapping is at least 50 metres wide. 

A total of 96 grab and channel samples were collected during two separate site visits to Lac Connelly. On average the samples returned 56.8% Fe203. 

Under microscopic examination the rock samples collected consist of coarse grains of hematite and quartz that are not intergrown but rather appear to form separate grains. 

There was no drilling at the Lac Connelly property to enable estimation of the DSO (direct shipping ore) potential for a mineral resource. 

It is recommended that drilling be initiated in the near term to delimit the actual extents of the iron formation in the Hematite rich DSO zones outlined by the field prospecting and sampling programs.

      

Report's Conclusion:

"Based on the sampling results and microscope exams it is recommended that metallurgical studies be conducted to test the beneficiation of the Lac Connelly hematite targets. If beneficiating of the metallurgical samples proves successful the property could be confirmed as a direct shipping ore (DSO) prospect. There is presently no drilling at the Lac Connelly property to enable an estimation of the DSO potential for a mineral resource. It is recommended that drilling be initiated in the near term to delimit the actual extents of the iron formations in the Hematite rich DSO zones outlined by the prospecting and sampling programs. The cost of the diamond drill program is estimated at 2 million dollars."
