NITRIC ACID.... Well of course ( giggles )
Majority of Wellgreen ores are Nickel Laterites - Silicates.
The DNi ProcessTM is a ground-breaking, patent-protected method for extracting nickel, cobalt and other constituent metals contained in laterite ore. Ensuring the sustainability of natural resources, our process maximises extraction, minimises cost, minimises residue and realises the full polymetallic value in earth’s lateritic resources. With the DNi ProcessTM, it becomes possible to evaluate the resource in a whole new way. There are more opportunities to profit – not just through treating low-grade ore – but also because the DNi ProcessTM extracts ALL the contained metals.
This full utilisation of the mine is something which other processes simply can’t achieve.
MORE METALS = GREATER REVENUE. It also means spreading the economic risk by introducing new markets, and not being reliant on the nickel price alone.
The bottom line?
The DNi ProcessTM is more profitable.
FASTER Our simple flowsheet means that plants can be constructed very quickly. In fact, in the hydrometallurgical world, a DNi Process™ plant is the fastest route to market from a standing start.
Take for example the Queensland Pacific Metals’ plant which will be ready to commission
just 14-months after breaking ground, and is set to produce 16,000 tonnes of nickel per annum.
With significantly lower operating costs, and fast, efficient plant construction.
The DNi ProcessTM makes the extraction of ‘battery-grade’ nickel and cobalt more achievable, more affordable and more profitable. In fact we’re promising to almost double the world’s nickel reserves whilst extracting all saleable metals from lateritic ore (Ni, Co, Sc, Fe, Mg, Al).
The DNi ProcessTM is a greener metal extraction technology. In fact it does not produce wet tailings which require containment dams or dumping at sea.
Our unique patented process consumes very little acid, typically 30-80kg of acid per tonne of ore processed. What’s more, over 99% of the nitric acid used is recovered and recycled. Containing magnesium nitrate, also known as fertiliser, the dry leach residue can be returned to the mine where it encourages the growth of native plants.
Zero waste. Zero toxic tailings. Zero need for deep-sea dumping or poisonous mine dams, the DNi ProcessTM is an environmentally conscious, green alternative.
With straightforward set-up,
our process is flexible and scalable with minimal risk.
The DNi ProcessTM is a simple metal extraction technology. We’re able to process the full lateritic ore profile with complete flexibility. This means we can blend the laterite limonite, saprolite and transition zone in almost any combination. Thanks to the simpler flowsheet and our use of nitric acid. Simple, economical, effective.
SAFER By eliminating the need to heat acid to dangerously high temperatures
under hazardous pressures.
- The DNi ProcessTM operates at 1 atmospheric pressure to leach ore.
- Metal extraction is achieved at around 110°C.

Wellgreen nickel grades were richer in % per tonne.
Fastforward,
Grades slowly decrease in %.
Whether dismal intercepts adding more tonnage of lessor grades
blended with existing or....
2017 press release stating the xps process would not include
silicate nickel.
That would indeed reduce the recoveries which inturn
affects the grade preception.
In the most recent 2023 ( pfs ) the admittence of,
majority of ore body is, silicate nickel.
DNi process could be the ideal path for NCP.
Should shareholders sit idley by and accept an extraction
that veers from specific nickels in laterites ?
Or...perhaps entertain other extractions like DNi ?

XPS PROCESS ( 2023 pfs )
Practical Entitlement recognizes that part of the feed metal units exist in a form that is either mineralogically unsuitable for recovery (e.g. nickel as low-concentration solid solution in magnetite or silicates) or in a form that is physically unsuitable for recovery (disseminated microcrystalline inclusions of metal sulphides within silicates).
These values can be compared to the physically achieved recoveries in metallurgical testing, which reveal the magnitude of process losses associated with upgrading. https://www.nickelcreekplatinum.com/investors/news-releases/press-release-details/2017/Wellgreen-Platinum-Announces-Results-of-Metallurgical-Testwork/default.aspx

Something to think about...
As simple as sending off 1 tonne to recieve a 3rd party report.
DNi process is patented.
Proven.
Such creates strong backing = PFS report.
If this simple solution worked.
Wellgreen deposit is unlocked.
Hydrofluoric Acid
is just as impressive.
Question becomes...
What's the junior's next move ?
ho hum.
Cheers...
