SENSOR BASED - ORE SORTING
Here's a video discussing - ore sorting.
It's actually quite new to the mining industry but quickly gaining traction due to it's incredible cost reductions and high grading the, feedstock with less waste ores to contend with.
Why evendiscuss ore sorting ?
Simply put - Rowan has most of it's gold in - quartz rock.
If 10% is quartz that would equate to 90% waste ores rejected.
Though some of the gold is in other host rock, evenstil, a sensor based ore sorter would completely change the dynamics of this project - reminder - brown field project.
Yeah... not green.
Supposing a hypothetical of, 90% waste ore reduction would place a concentrate - based on ore tonnage - in the ball park of, 22:1 ratio.
For every 22 tonnes of ore one tonne of concentrate ( x gram ) per finished concentrate tonne.
Basing the concentrate on - only keeping the gold bearing quartz..
As mentioned in last post -
- could open pit modelling for the Rowan be a better mine format ?
- how many additional gold ounces could be added if open pitted ?
- what new cut off could be considered if ore sorting were introduced ?
- could 0.5 grams be factored - after all - if the ratio of concenttrate is high the 0.5 grams could
double, triple, or incrwase the head grade all the more -
- what about the intercepts that are under 1.5 meters ?
- open pitting the ptroject would force the mine modelling to conisder most all grams.
A - 149/g intercept of 1 meter - would come into play.
Translated - it wouldbe equivelent to - 4/g intercept over 37m.
Which could also translate to - if the 149/g were captured it could result in, 36 meters of waste ore eliminated - which is all the more reason to open pit - and factor in - all intercepts from 1/g upward - and more importantly - would love ot see an over all average that includes the numerous high grade intercepts 1m and under... could the resource maintain an above 2/g average or higher - keep in mind - ore sorting allows for a highgrading - if it doesn't enter milling it would qualify as - gram grade prior to milling and extraction.
If it were me....
I'd place the NT zone on hold.
I would reasses what i have in the gorund with a remodel of the - 43 101
Rowan + NT.
NEW RESOURCE CALCULATION
MODEL EACH OPEN PIT
Crunch some numbers - see what it would cost to bring in a few ball mills.
Ore sorter...
Keep it real simple - flitstone operation.
Create a high grade concentrate
Sell the concentrate to nearby producer.
Keep the contract open ended - no locked in prices - price floats with gold.
Try to offer a consistent ( x grade ) concentrate
For the extra high grade - divert these ores - and table foat - junior handles the easy gold.
What would this project look like if continued on course of drilling ?
Versus.... open pit, crush, sort....sell concentrate ?
If other juniors have thier open operation running at a $750/ounce CDN feasability studies, then... what if a concentrate program could kepe the costs down to, $500/ounce / con ?
Using a spot gold @
$2200 - $500
= $1700
- $600 profit for junior
= $1100 for the con purchaser
= $700 con purchaser
Hypothetical of course,...
Helluva - lot better than, seiing the gold at ( bargain ounce prices )
letting a major make the majority of profits...
Ore sorting with open pit - in my minds eye - is far better than guessing and poking below trying to snype the gold.
It allows a far higher confidence factor - a confidence that allows the sensors to do much of the work - capturing only the best of ores and ensuring the targeted minerals are kept.
Will we see more juniors enter the production arena as technology offers incredible means to do so - taking much of the risk away form the equation ? Could ore sensor sorting be the nemisis to the Majors allowing more juniors to compete ?
I would say.... YES.
Times are changing...
Mining techologies are growing by leaps and bounds.
Juniors thinking old school will not make the cut = they should and must begin to utilize this tech - reduce the control of only a few majors who contorl the entire mining indusry.
Perhaps a portion of the reason as to why so many gold juniors are so under valued- i can't help but think that techologies such as ore sorting must place fear into the majors- wink...

Yes... it's a dry video, lol
But stick with it... there are gems along the way.
Such as, Russia is using XRI sensor tech for thie rgold mines.
Canada is just beginning ot wet thier feet with ore sorting.
Great for Brown field projects + green over LOM.
SINGLE SENSOR UNIT - ORE CAPACITY
300/T hour x 24/h
= 7,200 ore tonnes
Enjo the video....
RLG... sure hope they reevaluate thier 2 projects and consider open pitting.
Include all intercepts - scrap the cut off and reduce the gram req - i'd say it would breathe now life into this project - i know a few of the RLG team are up oin age, but, would they ever consider running a flitstone with ore sorter operation ?
Assembling a new 43 101 with open pit...
Is where this stock will take a turn.
Own opinion, not investemnt advice
Sure hope RLG still has the sting of when Gold Cor, sold 30% of RLG to Evolution -
Bounsing from major to major- is backseating it.
RLG should keep thier options wide open -
attract all others and not play apartie based on a 30% snag.... wink.
Building a project and selling it must be kept to - best offer takes it.
bulk ore samples...
i'd be creating my own contingency and grabbing a portion of the ores and running it thorugh a tech company with ore sorter - pilot plant.
Such numbers would be the perfect back up plan for RLG to counter a 30% snag.
Cheers....
