RNS Plant & Processing6 Jun 2023 08:29
Highlights
· Concrete work ongoing. Process equipment at location
· Special Use Permit now granted with NDEP approval expected August 2023
· Guidance on plant capacity and anticipated recoveries
· Independent calculations of material available for processing
· First revenues expected this year
Fantastic RNS outlining in great detail:
> JV = 50/50% with Muletown supplying site & plant & GWMO financing build & Commissioning from cash
> plant processing metrics = 5t/hour, 70+ hour week, 48 week year =16.8kt/year
>> stage 1 recovery = 50% Mill & gravity separation & feeds ...
>> Stage 2 recovery = 60% Heap leach (ie adds 30% metal recovery from input ore)
>> Overall Stage 2 recovery = 80% combined cycle
> summarised low/high case for available materials to be processed from existing ABOVE ground sources
>> Minimum JORC = 1,600oz Gold & 3,000oz Silver @OMCO mine
>> low case contained overall metal = 1,980oz Gold & 9,250oz Silver across MJ & OMCO
>> high case contained overall metal = 2,810oz Gold & 40,300oz Silver across MJ & OMCO
> Refining costs expected to be 10% post recovery from concentrate
> JV mill costs = not stated but GWMO will "recover" 50% as it is a JV 50% partner
> GWMO has also stated that there maybe additional above ground materials across its 60km^2 of claims
In summary
GWMO ability to produce a viable revenue stream from existing above ground materials backed by JORC compliant estimates for 50% of materials now looks nailed on. Additionally Stage 1 gravity separation plant will recover 50% of available contained metals with balance able to be stored onsite for Stage 2 recovery via Heap Leach when Stage 2 plant has been built.
GWMO has importantly also stated that existing plant throughput can be increased above stated 5t/hour at modest CAPEX and no additional OPEX costs so 16.8kt/year rate is a minimum.
