Perhaps....
When i see photos of other nickel ores - such as the example below -
I can't help but think -
did BMK overlook potential nickel credits in - hydroxide / sulphide and
other elements that can bond with nickel such as
,magnesium, aluminum, and a variety of..., ITES...?
wouldn't be surprised if there was also - cobalt in the nickel ore example below.
This first photo is not from - BMK.
All other photos are.
NICKEL ORES - ( GREEN AND BLUE ) https://img.100ppi.com/sunsirs_news/2022/09/05/b583901672748efeb9420b4860be2195.png 
Now... i've come across several articles on - irons oxidizing to green.
I don't think it's the iron.
Many reports will cover the topics of, iron in water... staining green.
Yet... they;re quick to point ot - iron.
Hard water.
I've seen several photos of - supposed - iron staining - and showing all sorts of colors.
Again... i don't buy it.
Most likely - other minerals with an iron.
Here's a classic article -
speaking about iron - and showing green oxidation, hydroxide staining.

Did you catch it ?
One could easily accept what's printed and run with it.
Or.... look at hte specimen and ask... is that really grene iron leaching out ?
Again.... did you catch it ?
What's written on the rock ?
Epidote.
Epidote is also known for - nickel mineralization. lol
I often wonder... how many minerals were missed and sold in concentrates...
I would say... a shhhh load.
Making another rich.
SUDBURY MINE - ore specimens....
Pause the vidoe - 1:14 min mark.
Sodatite.
green, bluish, rock.
Now think.... SPJ PROJECT - SODIC INTRUSION.
Ahhhh.....
WEB DEFINITION - The sodalite group has three main mineral types: sodalite (sensu stricto) ... Alloys and Alloy-like Compounds, with Copper, Silver, Gold, and Nickel. https://www.youtube.com/watch?v=f0CcSdW5fEc Cheers....
LOTS OF .... GREYS, BLUES.
look closely -
this core photo - has lots of dull greys.....
just exactly what type of pyrite ?
there's all sorts of pyrite.
what if there was - 2% nickel with in the pyrite ?
what if the lil mickey mouse metal detector - wasn't good enough to pick up on any nickel
hiding with in ?
