5 - SUDBURY NICKEL ASSOCIATIONS The main rock types present are; 1 - granite 2 - ( granite gneiss ) 3 - gabbro and 4 - basalt. Mafic norite also can form breccias layered on and or mixed within the granite breccia. This rock type is termed Sublayer in Sudbury. These two breccia types are the hosts for the copper-nickel orebodies that Sudbury is famous for. Basalt - limestones.
Sudbury does have - Nickel - in the limestones but Nickel is weaker in grade.
Limestones could be the causative to creating the - serpentine / chlortie colorations
along with irons.
What's the 2 PART - 5 th ( element ) ( smoking gun ) to pinpoint - Nickel Ores ?
SILICATE IRON- which host - all the ( I - T - E - S ) and Micas.
Sudbury Breccia is widely distributed within the footwall rocks that surround the Sudbury Igneous Complex (SIC) and is of economic importance because it hosts several of the
Ni–Cu–PGE sulphide deposits for which the area is famous.
BMK - has drilled lots of Breccia -
but majority of cores have only been assayed for - Gold.
Drill Hole - 20 - 046 - has the limestones.
Which makes it quite interesting to see that gold is with in this ore class.
Nickel, Copper, and PGE's begin to show themselves.
Now... what if Glade also has the - limestones ?
The pink charability map- does show the pink leading to - Glade.
What interests me most is...
What if the limestone ore is overlying the - host iron rock with all the micas and pyrites ?
Which is what i pointed in a former post - Are we only creatching the surface ?
What if were' - 100m - away from ( tapping ) into a high grade nickel ore body ?
What does the good nickel ore look like in - Sudbury ? Nickelite - Nickoline
MICAS - PYRITE - SILICATES

may have altered the state of the Nickel into - Nickel serpentine or chlorite.
I read another paper on - how the eastern and northern parts around sudbury have the Sudbury Igneous and Breccia at closer depths to surface than - Sudbury mines do.
There's an enormous amount of information on, Sudbury's Nickel - but when it comes to it's ores.. one has ot really sift - i wonder if it has something to do with,
keeping it well guarded...lol I would think if one kept it simple - looking for the - micas, iorns, silicates - chances are it would
put a junior on the nickel all the sooner -
What makes it so complex is... the sodic and lime intrusion.
Which is where one has to factor not only irons + micas and pyrites but also factor in,
how these indigenous ore bodies would alter if alkai limes and chlorite waters would change the minerals - hence - nickel chlorites.

LAST SUBJECT ? What does Sudbury look like - explorers and miners ?
Keep in mind -
Inventus, New Age Metals,
SPJ ( Mc Donald Mines ) Magna - is also with considerable lands.
Interesting.
That's the mine i've bene trying to find out what type of ores it has for it's Nickel,
given they're so close to the - Espanola serpentine's and limestones.
And.,, if the info above is not enough for your voracious mining appetite ?
Here's something really interesting - an article on, Volcanos and limestone
in Ontario. I tohught it was well written, quick article, and i couldn't help but tihnk of the
Great lakes and all the salt mining underneith, in conjunction with, phospherous, which is
hughly associated to - uranium - which at one point in time there was a uranium mine on an Lake Nipissing Island - which is associated to volcanos -
Throw in, phospherous levels in Lake Nipissing,
Uranium, then... toss in, Norstar mine = lotsa of calcium limes and phospherous,
then, Lake Wanapetei's batholith doesn't look like a crater hit it moreso, deep seated valcano, throw in all the sodics and many types of salts like aluminum, potasium, sodium, calcium, and then... tie in, the mine north of Kingston with a larger Great Lakes footprint, and keeping the faults in check - it could spell out - Ontario is in a volcano zone -
Oh... don't forget the ring of fire. wink.
