Who has the - bagged ores - from Western zone of deposit ? *****
Western side is where most of the - purple ore color - was seen.
Processing plant - took the impurities out - calcium carbonate out - bye, bye, cobalt.
- if... cobalt was present.
Tusk Exploration Ltd. (Tusk)
In late October and early November 2008, seven NQ diamond drill holes were completed from an area near the thickest part of the Western Magnesite, for a total of 692 m of diamond drilling. Core from this drilling was bagged and prepared for shipment to a lab, but was never submitted. This core was subsequently analyzed in 2012 by Torch River Resources (Torch River), who were considering an option on the property. Torch River decided not to proceed with the option. By 2013, the property was under agreement with Manto Gold Corp. (Manto), which filed a Notice of Work for 2014 diamond drilling.
In late 2013, MGX signed an arrangement with Manto and on July 7, 2014, the agreement was completed, making Manto a subsidiary. MGX conducted the diamond drill program, and followed up with a re-assay of the 2008 drill core. In 2015, MGX conducted another diamond drill campaign, and received permission to build a short access road.
The primary purpose of the road was to provide a secondary access route and shorten the haul distance for a proposed bulk sample. In 2016,
MGX drilled and blasted a bulk sample site at the East Zone and hauled approximately 100 tonnes of material to a laydown area for stockpiling, sorting, then hauled via highway truck
to a crusher in Invermere, BC.
Sixteen 25-L pails of sample materials (taken on a grid over the stockpile) were shipped to ALS Minerals (ALS) in North Vancouver for assaying and specific gravity (SG) analysis. A pilot plant was acquired, which is currently being shipped on six tractor-trailers from the Yukon to Invermere, BC. The pilot plant is a 50 t/d flotation plant previously used for concentrating lead-zinc-bearing material.
Once the plant is set up, the crushed bulk material will be processed to remove silica and calcium impurities and then re-assayed. Approximately 10 tonnes of the concentrate material will then be shipped to Industrial Furnace Co. of Rochester, NY, for calcining and kiln testing to produce CCM and DBM samples. Information gained from the testing will be used for kiln design.
WHAT'S THAT SAYING ?
If there is an error in proceedure from - get go - the error will continue all along.
Taking out the impurities along with calcium carbonates... may have also resulted in loss of a potential - cobalt credit.
Who has the bagged ores ?
Bagged ( core - ores ) in which Tusk Exploration assembled ?
WESTENR DEPOSIT ORES.
Why do i ask ?
Western Deposit - is the larger core body - and... is where all the purples were seen.
Not to dismiss/disregard - other lenses below grade that might harbor - puprle / pink colorations.
PEA REPORT -

2015 - tech report
PAGE - 7 - Surface rock chip sampling identified a 110 degree trending contact (dipping 72 degrees S), with a brown argillaceous dolomite (Hmn 2) to the north, and white to
purple colour siliceous magnesite (Hmn lb) to the south. The
West Zone - purple - coloured siliceous magnesite bed forms a topographic high
(ridge crest) on the north portion of the West Zone, that includes DDH 15-7, 7 A and DDH 15-11, 11A (Fig 9).
The
purple magnesite bed covers an area of 30 X 350 meters and appears to be a separate magnesite zone that is 20-100 meters north of the main
West Zone magnesite that
covers an area of approximately 100-200 X 400 meters. --------------------------------------------------------------------------------------------------------------------------------
Separate magnesite zone with - purple colorations.
Located 20 - 100 meters- north of west zone.
PURPLE Magnesite covers an area of - 30m x 350m
My wonderment is.... was this an outcrop ?
Did foliation cover more of this - purple ore body ?
350m is nothing to sneeze at -
can i hypothetically add a few more meters for it's shoulders ?
most deposits are wider than what is seen at surface.
350 m strike ( confirmed )
x 100m wide ( i added more )
x 25m lense ( thickness below grade 0 assuming it's sedimentry style.
x 2.5 ore weight ( factoring for metric )
= 2,187,500 ore tonnes ( 2200 lbs )
Can i use a modest cobalt value of ( 0.005 % ) 1/2 percent ?
2,187,500 / t
x 0.005 % Co
= 10,937.5 tonnes
x 2200 ( pound conversion )
24,062,500 lbs
$24/ lb ( current spot prices )
= $577,500,000.00 usd
x 1.30 conversion
= $750,750,000.00 cdn ( again - hypothetical - to provoke a reason to test for cobalt )
What does the eastern hold in - purple and pink ? When MGX acquired it - they worked over the eastern side.
Tech report said- when the magnesite ores was broke - it turned
pink. And of course - this intelligent report on the - cobalt's inability to leach out.
Which suggests - it gets left behind.
.
Cobalt carbonates pose a serious metallurgical problem. Most carbonate ores are processed by solvent extraction using acid. Solubility calculations indicate that the Co in carbonates is less soluble than Mg, Fe, and Ca by 3 to 4 orders of magnitude.
Thus, acid leaching will liberate all other ions from carbonate ores before releasing appreciable Co. Furthermore, many of the
Mg-rich spherocobaltites in this study were initially misidentified as Co-rich dolomite, which is far more soluble than spherocobaltite. This may cause Co recoveries to be lower than predicted at many Central African Copperbelt mines.

Gald i did - catching the removal of the - carbonates before - assaying.
Boom chuka lucka - please do test the Tusk core ores - western zone - in bags.
Re assay the eastern zone ores - with calcium in .
Thanks.
Cheers....
