Itafos Files and Announces Results of Updated Itafos Conda Technical Report, Increasing Mineral Reserves and Successful Mine Life Extension Through 2037

Itafos Inc. (TSX-V: IFOS) (“

Itafos

” or the “

Company

”) is pleased to announce today that it has filed an updated technical report for Itafos’ Conda project (the “

Conda Technical Report

”), a vertically-integrated phosphate fertilizer project in Idaho (the “

Conda Project

”). The Conda Technical Report demonstrates increased Mineral Reserves and the opportunity for continued operations at the Conda Project through 2037.

The Conda Technical Report, titled “NI 43-101 Technical Report Itafos Conda Project Idaho, USA,” with an effective date of July 1, 2023, was prepared for Itafos by WSP USA Inc. (“WSP”) in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”). The Conda Technical Report is available on SEDAR+ (www.sedarplus.ca) under the Company’s issuer profile and on the Company’s website (www.itafos.com).

Technical Report Highlights for Conda Project:

• The mine schedule shows ore production for the Conda Project through 2037.
• The Mineral Resource estimate for Husky1-South Maybe Canyon (“H1SMC”) and North Dry Ridge (“NDR”) (collectively “H1/NDR”) increased from 38.1 million short tons (dry) at ~24.3% - ~27.0% P2O5 to 40.5 million short tons (dry) at ~24.2% - 26.7% P2O5.
• The total estimated Mineral Reserves for Conda increased from 14.4 million short tons (dry) at ~26.6% P2O5 (as of July 1, 2019) to 33.7 million short tons (dry) at ~25.0% P2O5 (as of July 1, 2023).
• The Rasmussen Valley Mine (“RVM”) block model did not change based on the results from reconciliation between the 2019 model estimates and the production results up to the effective date of the Conda Technical Report (July 1, 2023). The estimated remaining Mineral Resource after the effective date of July 1, 2023 is 5.9 million short tons (dry) at ~25.9% P2O5. The estimated remaining Mineral Reserve after the effective date of July 1, 2023 is 4.3 million short tons (dry) at ~26.0% P2O5.

David Delaney, the Company’s CEO commented, “The updated Conda Technical Report validates and updates the proven and probable reserve estimates that support the H1/NDR project with proven mine life through 2037. Following the Notice to Proceed in May 2023, we have been working diligently on capital activities associated with the H1/NDR project with H1/NDR ore recovery expecting to start in late 2024. The Conda Technical Report and associated capital activities are the culmination of our strategic objective of extending Conda’s mine life.”

The Conda Technical Report includes Mineral Reserve estimates for RVM and H1/NDR, all of which are wholly-owned by Itafos Conda. The Mineral Reserve estimates for these deposits were prepared by WSP and this news release is the initial public disclosure of such Mineral Reserve estimates.

The effective date for the Mineral Reserve estimate is July 1, 2023. There have been no material changes in the available information for the deposits between the effective date of the Mineral Reserve estimate and the date of this news release.

Notes:

1. A moisture content of 11% was assumed to convert from wet short tons to dry short tons.
2. A 97% mining recovery and 0% dilution was applied to the tons selected as ore.
3. A P2O5 cutoff grade of 20% was assigned as the minimum grade to be considered ore. Grades are reported in dry basis.
4. A pit optimization analysis was performed on the H1SMC deposit, which incorporated the geotechnical parameters, mining costs of $3.06/t wet overburden, $4.61/t wet ore, ore stockpiling and shipping costs of $11.21/t wet. A Gross Margin available per mined P2O5 ton (applied at the point of exchange of the tipple) of $283.70/t dry ton P2O5 was used to define the limits of the mining pit. The total processing costs are not disclosed in this report but are higher for H1SMC relative to NDR due to an MgO reduction circuit required for H1SMC.
5. A pit optimization analysis was performed on the NDR deposit, which incorporated the geotechnical parameters, mining costs of $3.06/t wet overburden, $4.61/t wet ore, ore stockpiling and shipping costs of $11.21/t wet. A Gross Margin available per mined P2O5 ton (applied at the point of exchange of the tipple) of $283.70/t dry ton P2O5 was used to define the limits of the mining pits. The total processing costs are not disclosed in this report but are higher for H1SMC relative to NDR due to an MgO reduction circuit required for H1SMC.
6. All stockpiles, which includes WV Tipple and plant stockpiles, total dry tons, and average P2O5 grades are displayed.

About the Deposits

The phosphate mineralization encountered at the deposits considered in the Conda Technical Report occur as stratigraphically controlled sedimentary phosphate mineralization within the Meade Peak Member of the Early Permian Phosphoria Formation. The Meade Peak Member is further subdivided into an Upper Phosphate Zone and a Lower Phosphate Zone, separated by an unmineralized Center Interburden Zone. The Mineral Reserve estimates include mineralization from both the Upper Phosphate Zone and Lower Phosphate Zone.

Project Risks

Project risks have been outlined in the Conda Technical Report along with mitigation plans to de-risk the Conda Project. Costs have been estimated to a level of accuracy suitable for a Preliminary Feasibility Study. Overall economic risks include financing, price escalation, inflation, commodity sales price variability and general global economic conditions. General technical risks include project construction timeline, surface water management, geotechnical uncertainty, mining productivity, achieving optimum P2O5 grade and recovery, and waste management.

Cautionary Note Regarding Mineral Resource and Mineral Reserve Estimates

This press release uses Mineral Reserve and Mineral Resource classification terms that comply with reporting standards set forth in NI 43-101 for all public disclosure of scientific and technical information concerning mineral projects by Canadian registered issuers. NI 43- 101 standards differ significantly from standards set forth by the United States Securities and Exchange Commission (“SEC”). Therefore, information regarding mineralization presented herein may not be directly comparable to similar information disclosed by companies in accordance with SEC standards. For instance, Mineral Reserve estimates contained in this presentation may not qualify as “reserves” under SEC standards. The reader is cautioned not to assume that any part or all of the Mineral Resources identified as “Mineral Resources,” “Measured Mineral Resources,” “Indicated Mineral Resources” and “Inferred Mineral Resources” in this presentation will ever be converted into Mineral Reserves as defined in NI 43-101, be upgraded to a higher category, or be economically or legally mineable.
