SAGUENAY, QC

,

June 27, 2024

/CNW/ -

Arianne Phosphate (the "Company" or "Arianne")

(TSXV: DAN) (OTC: DRRSF) (FRANKFURT: JE9N)

,

a development-stage phosphate mining

company, advancing the Lac à Paul project in

Quebec's

Saguenay-Lac-Saint-Jean region, today is

pleased to announce results from its prefeasibility study ("PFS"). As per the Company's

Press Release of

January 30, 2024

,

Arianne commissioned a PFS to consider the viability of

constructing a purified phosphoric acid ("PPA") plant in the Saguenay region of

Quebec

to transform

igneous-based phosphate concentrate into a battery-grade phosphoric acid for use in the lithium-

iron-phosphate ("LFP") battery.

As studied, the downstream facility would be capable of producing 350,000 tonnes (100% P

2

O

5

basis) annually of PPA, making the plant the largest producer outside of

China

. At 350,000 tonnes,

Arianne's supply could address roughly 350 GWh of yearly Western gigafactory demand. Industry

analysts such as CRU, Benchmark and McKinsey, see a significant shortage of PPA by the end of

the decade as traditional demand from food additives and surging demand from the LFP battery

greatly increase the needs for PPA, well beyond current supply availability.

In addition, Arianne's facility would produce 220,000 tonnes (100% P

2

O

5

basis) annually of a

secondary phosphoric acid used in the production of specialty fertilizers and animal feeds. The

market for this product will also be facing severe restrictions as current producers of this product

are limiting their output due to operating constraints.

"Opportunities like this don't come along often," said

Brian Ostroff

, President of Arianne Phosphate.

"Access to a high-quality phosphate concentrate, the ability to economically produce PPA for use in

specialty applications and the advent and growth of the LFP battery provide extremely compelling

economics with a pre-tax NPV of over

US$4.5 billion

. Further, the study also demonstrates the

opportunity for our Lac à Paul mine to have a local customer. In looking at the two projects in their

entirety, the Arianne companies would provide enormous benefit to its stakeholders and unlock

significant value for its shareholders."

Economics

Capex

The full downstream operation is projected to have an initial Capex of roughly

US$1.65 billion

, which

includes a contingency of approximately

US$240 million

. The Capex covers logistics for a phosphate

concentrate transportation system on the south shore of the Saguenay River, an on-site sulphur

plant for the production of sulphuric acid and, both a merchant grade acid ("MGA") and purified

phosphoric acid plant.

Opex

The primary determinant in the operating costs for the PPA facility is the input cost of the phosphate

concentrate (79%), the cost of sulphur used in the production of sulphuric acid (14%) and other

miscellaneous operational costs such as maintenance, staffing and consumables (7%).

For the purposes of the economic model, internally built based on the Company's PFS, Arianne used

an input cost of

$213

/t for the phosphate concentrate which is consistent with the Company's

previously published bankable feasibility study ("BFS") for its Lac à Paul project. As per the BFS

(

October 24, 2013

), at a sale price of

$213

/t, the Lac à Paul mine had a NPV (8) of roughly US

$1.9B

. Using

$213

/t, the cash operating cost for the PPA facility would be

$1,195

/t. According to

Benchmark Mineral Intelligence (Phosphoric Acid Market Outlook, Q1 2024), any production under

$1,450

/t would be regarded as a low-cost producer of PPA.

As well, the 220,000 tonnes of secondary acid would be a byproduct of the PPA production process

and thus, would not have an additional production cost associated with it. Revenue derived from the

sale of this acid would be a direct credit adding to the PPA facility's bottom-line profitability.

Revenue

The PPA facility would generate revenue through the sale of its finished products. These products

include 350,000 tonnes of PPA at

$2,300

/t, 220,000 tonnes of secondary acid at

$1,200

/t and 3

million tonnes of gypsum at

$10

/t, a product produced through the conversion of phosphate

concentrate into phosphoric acid. These prices are based on reported sales prices from several

data providers and publicly available sources. The sales prices of the two classes of phosphoric acid

represent a discounted 3-year average. The project would also generate surplus electricity that

could be sold into the grid however, this has not been accounted for in the Company's internal

revenue model.

Environmental Factors

According to the study, the downstream PPA facility would be able to take advantage of numerous

operational benefits designed to mitigate its environmental impact. By having access to a high-

quality, low-contaminant phosphate concentrate, the facility would require less input material thus

requiring less transport and handling of the feedstock versus other facilities. As well, by using an

igneous-based phosphate concentrate, the facility's output of PPA would be at a much higher ratio

than most other operations allowing for a smaller operational footprint for its production size and

superior economics.

The facility would also consist of a sulphuric acid production plant. The study shows that by choosing

to construct its own plant to produce sulphuric acid, the operation would substantially reduce the

environmental risk associated with transporting material in acid form and, greatly reduce the needs

from a transportation infrastructure by moving three times less the material.

Further, by producing sulphuric acid through the direct input of sulphur, the facility would be able to

be a net producer of electricity through the capture of steam through turbines that will generate

electricity. This power would allow the facility to run without the requirement of external energy

sources and allow the facility to sell its excess electricity into the electrical grid for the benefit of the

regional community.

Lastly, a byproduct in the production of phosphoric acid is gypsum. As most phosphate concentrates

contain radioactive contaminants, the gypsum produced is a hazardous material that needs to be

stored, creating a legacy environmental issue and operating expense. As per the PFS, in the case of

the Arianne facility, the use of a high-purity, low-contaminant phosphate concentrate would allow the

production of a marketable gypsum, generating revenue for the operation where many other

operations incur a legacy cost. Further, the environmental footprint and impact would be greatly

reduced as the gypsum would not have to be stacked and maintained on the property.

Operational and Economic Benefits

In addition to the significant environmental benefits that would be provided by Arianne's downstream

facility, the study highlights operational and economic benefits as well. By using high-purity igneous

phosphate concentrate, the downstream product mix will be targeted towards specialty markets

projected to be in significant shortages in coming years allowing less competition and higher

margins. The production of additional marketable products such as gypsum and electricity, would

also allow for revenue streams beyond traditional phosphate-based products. Input of higher purity

concentrate also allows for greatly improved operating margins as lower input volumes [and costs]

will generate higher revenues.

Geographically, the project has numerous advantages. By situating the downstream project in

Saguenay,

Quebec

, the facility will have easy availability of high-quality igneous phosphate with

access to the necessary infrastructure required to build and operate a project of this size and scope.

In place there is a preexisting port, rail and a road network to provide for easy transportation

logistics allowing access to the emerging Western battery ecosystem in

Quebec

,

Ontario

and, the

American auto manufacturing markets in

Michigan

and the southeast

United States

. The Saguenay

region also provides the availability of a highly skilled workforce and has shown strong social

acceptability for large scale industrial projects.

"A lot of factors have come together that allow for this opportunity," said

Raphael Gaudreault

, COO

of Arianne. "As this study clearly shows, the opportunity is here for the Saguenay to become a major

player in the essential phosphoric acid industry. The project checks so many boxes; security of

supply, easy logistical access to a critical mineral, minimal operational challenge and very impressive

economics, all within the context of a high ESG standard. As a mining professional of over 20 years,

I can say that it is extremely rare to have everything come together in such a coherent fashion."

Geopolitical

Phosphate has been known primarily as an agricultural commodity necessary to enhance crop yields

and provide the food we need. Many jurisdictions, including North &

South America

,

Western Europe

and parts of

Asia

run deficits and require imports to meet this growing demand. These deficits have

been offset through imports from jurisdictions that historically have suffered from periods of unrest or

jurisdictions that have competed with the West to secure natural resources. Today, although most

phosphate is still used for fertilizer (~85%), the advent of new advanced technologies, such as the

LFP battery, have placed an additional demand on phosphate.

Understanding the necessity of phosphate in both food production and technologies required for the

transition away from fossil fuels, several jurisdictions have placed phosphate on their critical mineral

lists. Most recently

Canada

has joined two of its Provinces,

Quebec

and

Ontario

along with the

European Union in adding phosphate to its Critical Mineral List. The addition recognizes the

importance of the mineral as well as the very challenging "security of supply" issue.

The Lithium-Iron-Phosphate Battery ("LFP")

The LFP battery was originally developed in the mid-1990s and today is one of the more prominent

battery chemistries. Last year, the LFP accounted for roughly 35% of all batteries and, as more

Western car companies (Tesla, Volkswagen, GM, Ford) have announced that they will be adopting

the technology, the LFP battery is projected to be the most widely used chemistry. Superior

characteristics such as safety, lifespan, charging efficiency and cost have all driven the demand for

these batteries and made access to the LFP a growing priority.

As well, beyond the EV, the LFP's attributes have made it the premiere battery for use in Energy

Storage Systems ("ESS"). Analysts such as Wood Mackenzie see the growth in the ESS market

accelerating demand for LFPs and believe that over 30% of all LFPs will be used in the market

segment by 2030.

A significant challenge for the West is Chinese dominance in LFP battery production. Today,

China

produces over 95% of all LFPs with two companies alone (BYD & CATL) representing 70% of the

entire market. Growing tensions between

China

and the West have led to a policy shift, with many of

these governments now having adopted programs to accelerate the manufacturing of these

advanced technologies in the West. Beyond Western manufacturing, many of these government

programs also incentivize the sourcing of key critical minerals from Western jurisdictions.

The LFP battery requires PPA, a product that

China

also dominates. Growing demand for the LFP,

along with current uses for PPA, have industry analysts predicting a significant deficit by the end of

the decade. Benchmark Mineral Intelligence forecasts a deficit reaching 1 million tonnes annually by

2030, thus requiring a significant buildout of supply and, in particular, if the West is to become self-

sufficient, this supply will need to be built in the West.

In closing, Mr. Ostroff added, "the publishing of this study should be very helpful as we look to

conclude on our discussions with potential partners and financiers. Between the strong operational

benefits, the strong economics and the acknowledgement of phosphate's importance by its addition

to both the Federal and Provincial critical mineral lists along with the governments' willingness to

help, there is no reason why Arianne can't be the premiere operation in the West and, arguably the

world."
