Acquisition of Ferronickel Processing Equipment

Horizonte Minerals Plc, (AIM: HZM, TSX: HZM) ("Horizonte" or the "Company") the nickel development company focused in Brazil, is pleased to announce that its wholly owned subsidiary Araguaia Niquel Metais Ltda. ("ANM") has entered into an asset purchase agreement ("Agreement") to purchase certain new and unused ferronickel processing equipment (the "Processing Equipment") from Companhia Brasileira de Alumínio ("CBA"), a company listed on the B3 (Brazilian Stock Exchange), controlled by Votorantim SA ("Votorantim"), one of the largest industrial and financial investment holding companies in Latin America.

Highlights:

· The Processing Equipment comprises the key components of a conventional rotary kiln electric furnace plant ("RKEF"), excluding the furnace, and is expected to provide meaningful synergies in relation to the development of Horizonte's 100% owned Araguaia ferronickel project ("Araguaia" or the "Project")

· The Processing Equipment is designed and manufactured by leading international vendors with similar capacity and technical specifications to Araguaia and is already located in Brazil at CBA's Niquelândia Operations

· The Company is evaluating the use of selected components as spares and back up as part of the development of the first RKEF line at Araguaia but sees the key value in utilising some of the large-scale equipment, including the rotary kiln, to fast-track and lower the cost of development of a second RKEF line at Araguaia

· Use of the Processing Equipment will be integrated into a new study on the development of a second RKEF line at Araguaia

· The Agreement provides for a low upfront cost of US$600,000 payable in cash on signing with total potential consideration of up to US$7,000,000, with the balance payable upon the achievement of future milestones related to the development and operation of Araguaia

Horizonte CEO, Jeremy Martin commented: "The acquisition of the Processing Equipment is a compelling opportunity for Horizonte to fast-track the development of a second RKEF line at Araguaia, to reach 28,000 tonnes of nickel per year, and at a lower development cost. We expect to be able to realise significant savings on our planned development costs given the low cost acquisition of this high quality equipment relative to the original purchase cost of approximately US$60 million.

Today's news follows the announcement of the US$633 million funding package for the development of the first RKEF line at Araguaia. Fully funding phase one of the Project is transformational for Horizonte and the ability to fast-track phase two highlights our ambition to become a globally significant nickel producer. The execution of construction of the first RKEF line is our priority, but I believe this is a significant step in realising our vision for the full potential at Araguaia.

With a strong outlook for the nickel price underpinned by growing stainless steel and EV battery demand driven by the clean energy transition and limited new supply with comparable credentials to Araguaia, Horizonte is well placed to capitalise on the significant emerging nickel market deficit."

Background

The design and manufacture of the Processing Equipment was originally commissioned by Votorantim in 2006, as part of a proposed ~US$250 million ferronickel development at Niquelândia in Goiás State, Brazil. The project was expected to have an initial mine life of 20 years, with a capacity of approximately 42 ktpa of ferronickel (~10 ktpa of contained nickel) however, construction was halted due to the fall in nickel prices in 2009. The project was placed on care and maintenance during construction and ultimately never completed.

Horizonte and its engineering contractors have undertaken substantial due diligence on the Processing Equipment and concluded that it is well suited for use as part of the development of the second line at Araguaia. The Processing Equipment was manufactured by leading international suppliers and has been well maintained by CBA since the project was placed on care and maintenance with very similar technical specifications and design capacity to that being proposed at Araguaia. The Processing Equipment includes the following key categories of equipment: substation, crushing, rotary kiln, coal system, refining, conveyors, electrostatic precipitator, cooling tower and pneumatic dust collection.

Transaction Structure

ANM has entered into the Agreement with CBA to acquire 100% of the ferronickel Processing Equipment. As part of the transaction CBA will continue to perform care and maintenance activities going forward until it is removed from the existing site.

The total consideration of up to US$7 million payable by ANM will be paid according to the following schedule:

a) US$600,000 payable on execution of the Agreement;

b) US$950,000 upon the removal of 80% of the Processing Equipment from CBA's Niquelândia operations;

c) US$950,000 upon reaching 50% completion of Araguaia plant construction;

d) US$1,150,000 upon production at Araguaia reaching 90% of nameplate capacity for a period of 60 days, on average, and with up to 50% of such amount payable in Horizonte shares, at Horizonte's election; and

e) US$3,350,000 payable by Horizonte in three equal annual instalments with the first instalment due within 45 days of the first sale of ferronickel to a third party. Horizonte may choose to pay the outstanding balance of this amount at any time of its choosing with up to 50% of the total able to be paid in Horizonte's shares, at Horizonte's election.

About Horizonte Minerals:

Horizonte Minerals plc (AIM & TSX: HZM) is developing two 100% owned, tier one projects in Parà state, Brazil - the Araguaia Nickel Project and the Vermelho Nickel-Cobalt Project. Both projects are large scale, high-grade, low-cost, low-carbon and scalable. Araguaia is construction ready and is expected to produce 29,000 tonnes of nickel per year to supply the stainless steel market. Vermelho is at feasibility study stage and is expected to produce 25,000 tonnes of nickel and 1,250 tonnes of cobalt to supply the EV battery market. Horizonte's combined near-term production profile of over 50,000 tonnes of nickel per year positions the Company as a globally significant nickel producer. Horizonte is developing a new nickel district in Brazil that will benefit from established infrastructure, including hydroelectric power available in the Carajás Mining District.
