MacDonald Mines Exploration Ltd MCDMF


Primary Symbol: V.BMK

MacDonald Mines Exploration Ltd. is a Canada-based mineral exploration company. The Company is focused on the evaluation, acquisition, and development of precious and critical metals properties in Ontario. It is primarily focused on locating an economic deposit within its 100%-owned Scadding-Powerline-Jovan (SPJ) Project in Northeastern Ontario, located 20 kilometers east of the prolific Sudbury Mining Camp. The SPJ property consists of the Scadding, Powerline, Jovan, Blueberry, Loney and Golden Copper properties located east of Sudbury in Northern Ontario. The SPJ Project is targeting a system of interconnected precious and critical metals mineralization zones on an underexplored land package, which hosts the past producing Scadding Gold Mine and multiple known critical and precious metals prospects and showings. It also covers a Metasomatic Iron and Alkali-Calcic (MIAC) mineral system that formed polymetallic Cu-Au and Au-Co, Au, Silver, and REE exploration targets.

SCADDING MINE - INTERMEDIATE LEVEL - GEOLOGY

SCADDING MINE - INTERMEDIATE LEVEL - GEOLOGY Found an older PDF speaking about Scadd and other surrounding mines.

To my surprise -
it mentioned assay results from the ores of Scadding Mine -
middle ore body -

What stood out ?
11 % - 17% Aluminum.

Much higher than the 6% grade - I used.

No matter the report i read on the Scadd,
There's lots of salts, carbonates and chlorite alterations.

EXCERPT FROM - PDF -
The g o l d - bearing m in e r a liz a tio n occurs as sm aller zones w ith in the b r e c c ia s and are r e la t e d to c h l o r i t e  c o n te n t.  The p r in c ip a l  su lp h id e  in the East-W est zone was
a rsen o p y rite - -  w h ile p y r ite dom inates the In term ed iate Zone.

Several d i a b a s e d y k e s , up t o 10 m w i d e , c r o s s t h e p r o p e r t y i n a northw est d ir e c t io n . The ore is d e s c r ib e d by Harper (1983) as b ein g s t r a t ig r a p h ic a lly and s t r u c t u r a lly c o n tr o lle d .


WHAT JUST OCCURED TO ME ?
The dykes are not fractured like breccia.
Other rocks are not fractured like breccia.

Which means... it is a controlled system, whereas, dykes and outcrops would and could control other - float rocks - like breccia - into low lying areas - going around the outcrops - and settling out - then, covered by other sands and rocks to overlye a breccia.

Scadd is in a some what a lower depression.
Perfect to recieve breccia ores.

North Pit is at the tip of the Bristol, wide open to recieve float breccia, allowing the tip of the Bristol outcrop to collect incoming rocks.

The bristols north end shamfers showing errosion which would fit the model of,  watershed incoming from, Wanapetei or up north.

With the elongated outcrops running north to south - one could assess their errosion characteristics to see which way would support where the breccia came in from.
Wink.

In my opinion, gold is not from the chlorites.
It's from the breccia host rock.

If the Scadd ore body has moreso - pyrite - it's just a qwuation of - what kind.
East West Pit - is said to host - Arsenopyrite.
Big difference. Areseno pyrites are noted for - cobalt, nickel.

EXCERPT -
  A nalyses of nine s a m p l e s b y H o r s t  (MP91, p . 1 1 5 )  sh ow  N a 2O  v a l u e s 
r a n g i n g  fro m  a  lo w  o f  4.20%  ( h i g h MgO and FeO i n d i c a t e  a  c h l o r i t e - r i c h r o c k ) t o a h i g h o f 9.64% o r 81% o f p u r e a l b i t e .

Albitite - aluminum.

WHAT ABOUT THE TITANIUM  - SCADD INTERMEDIATE LEVEL ?
3 ROCK SAMPLES -
T i O2  -  0.41% - -  0.31% - -  0.16%

Those are percentage values, not - ppm.
0.41% = 9 lbs of titanium per tonne.

Would love to see a " whole " averaging value of the Scadd and North Pit and East pit
to see if the titanium has similar values.

Perspecitve ?
@ 0.41% TiO2
Every 244 tonnes = 1 tonne of Titanim

$39,000 tonne spot
~ 2200 lbs
= 17.72 / per pound
x 9 lbs per tonne @ 0.41%
= $159.48 cdn / value of titanium per each tonne of ore  ( another way of looking at it )


The pdf state aluminum values from intermediate Scadmine - 3 samples - 
Al 2O3 - 17.50%  -  16.20%  -  11.10%

About - 15% average
= 330 lbs of aluminum
x 1.34 cdn
= $442.20 cdn per tonne - note: if Al grdes were consistent.


GOLD - suppose 5 grams per tonne - similar avg grade of past explorers
2200 spot
~ 31.1 grams
= $70 per gram
x 5 grams
= $350 / per ore tonne

See why adding...
a few more credits like titanium and aluminum makes sense ?


Like i was saying - if one were applying an electrolysis - looking for other mineral credits and converted to - metals ... they'd fetvch a far higher price -

3 ROCK ASSAYS - MgO values Scadd  - intermediate level - were about - 5% avg.
Not rich enough to work with.
Would be nice to know what the Mg values in our Scadd carbonates are...

BUT.....
Manesium is far higher in grades- at Red Rock...
Percentages of lime + Mg - appear almost as - DOLOMITE -

REDROCK -
A p i e c e  o f  t h e c a r b o n a t e  was  s e n t  t o  t h e  P r o v i n c i a l  A s s a y e r , 
W. K. M c N e i l l ,  f o r  a n a ly s is , and  the  r e s u lt  ob tain ed  was:

Per cent
C a r b o n a t e  o f  l i m e ............................................50.82
Carbonate of  m agn esia ................................ 31.50

What does 31.5% translate to ?
693 pounds

If converted to a metal ( $4,300 ) per tonne cdn
Approx - $1.95 per lb

693 lbs
x 1.95
= $1,351 - metal value per tonne -


Would be idea to - chase the - gold + aluminum + titanium at Scadd...
And a second operation pulling out Magnesium to convert ot metal - if we had similar Mg
values in carbonates  -

Run a - 4 mineral - electrolysis -



Anyways - thought  i'd  share.


Cheers....
