REEF DEPOSIT ?What defines a reef deposit ?
Is it oceanic waters ( corrosive salts + limes ) that intrude and diseminate the host rock in which liberates minerals along with gold to drop out and settle and reform into secondary deposits that are considfered - reconsolodated ?
North of Superior lies the Hammond reef deposit.
In this reef deposit we can find the key ingredient - breccia in which gold is found.
While researching - Sudbury's crater zone - i came across a - cross section - diagram that depicted a lower strata - breccia zone - a zone which hosts fractured / broken rocks.
The impact diagram - isolated the impact crater zone - but... with a sharp eye, one could see this breccia zone stretched further well beyond the impact zone - which if conclusive - would mean there's a far larger breccia horizontal strata band that runs beyond the impact zone.
Many think the meteor impact caused this breccia strata fracture - but could there be another plausable reason that may have caused this breccia strata layer especially if it rextends beyond the impact zone ?
In a few of my searches along the Huronian,
I did come across some interesting geological fault zone maps that depoicted the Grenville fault along with a Huronian intrusion. Two distinct geological formations colliding - Huronian intruding into the upper geological formation that meets the Waniptei Lake area.
Such an intrusion " could " also give reason in which might have caused a distinct breccia zone.. Two geological formations colliding would fit the bill - inwhich could also create a fractured breccia to form. Just my own opinion of course.
Scadding Mine -
If one analyzes the Scad - pit zones - what stands out to me is....
Each of the pits are located in depressions - lower elevations - which does suggest therer's a pattern that might of bene overlooked -

Gold coud very well come from the iron host rocks ( iron or veins ) - but...
what do the cores speka in visuals ?
Is there significant chlorite ? ( salt waters + iron ) = chlorite + chromite.
Is there breccia ?
Is there sand granuals showing diseminated values ?
Are there quartz chunks but what is that other creamy colored rock ?
Could the creamy colored rock be = calcite ?
How about the gold - is that a chunk of gold and not vein gold ?
Could this gold be gold that drpped out and was captured in a secondary formartion ?

Could the Great Lakes once been apaert of the ocean ?
How does one explain away the - lime caves - benieth Huronian waters ?
Calcite + Limes = corrosive waters.
Thrwo in lower elevations where lime and calcium waters could intrude and work over the iron moiunds - it would stand ot reason gold could have liberatred and dropped out and accumilated in hte valley's such as the Scad pit zones.
Is naming the Powerline zone a smart move ?
Or, should this zone along with Glade be extensions of the - Scad Mine ?
Is there a large carbonate zone to the west of Scad ?
Is there a realtion to this zone and the gold ?
There's a distinct elevation depression at the main Scad mine and to the immediate west a rasied elevation, and, a pathway in coming from the north west seen in first video above -
could these pathways be former tranient paths for corrosive waters ? If we were to flood the Scad, Alwyn, Powerline, Alkin, Wanipitei river, and Glade areas, what would it look like with 3-5 meters of water ? What about Huron - would it interconnect via lower elevations even with Qanipitei Lake ? What's the small elevatrion of land that stretches from Massey towards River valley -backside of crater zone and Wanapitei Lake = could it be an escarpment created by former Huron Lake boundaries ? .

Should Scad encompass a larger fottprint or, should each zone be labelled indifferently ?

On ceo.ca -
a poster mentioned a potential name change - what an opportune time to evaluate all the work performed on the Scad area and consider what kind of gold is host ot this area and how it's found in what kind of formation - i'd hate to see this area renamed with a label that might not descibe the arera as it should - given Hammond reef aswell has the breccia gold.
It would be interersting to see a comparison of the breccia gold from Hammond reef and compare it with the breccia from Scad area - characterization and depths - perhaps Scad is closer ot the surface - from surface to 100m -
Perhaps tracking this breccia - in a sedimentry mind set - horizontal bedding - would be the ideal way to map this unique gold system - ?
Just open thoughts....
Cheers....
