1.

We note that you have disclosures throughout the filing referencing a Scoping Study, which is listed as Exhibit 15.1, originally filed July 1, 2022 on Form 6-K. Please discuss this terminology with the qualified persons as it appears the technical report summary should be identified as an initial assessment, rather than a scoping or conceptual study, to utilize terminology that is prescribed by Item 1300 of Regulation S-K.

Unless you or the qualified persons do not believe the report meets the definition of an initial assessment, which would be necessary to support your disclosures of resources, please arrange to obtain and file a revised technical report summary that is properly identified as an initial assessment rather than a scoping study, and similarly conform your references to the report in your filing. However, if you do not believe the report would be properly characterized as an initial assessment, tell us the reasons in your response.

Response 1: In response to the Staff’s comment, we plan to file a revised technical report summary that is properly identified as an initial assessment rather than a scoping study, and conform our references to the report in our filing of Amendment No. 1. We agree that our report would qualify as an initial assessment, which Item 1300 defines as a preliminary technical and economic study of the economic potential of all or parts of mineralization to support the disclosure of mineral resources.

2.

We see that you have included a map on page 47, which appears to show the general location of the Titan Project. However, you must describe and illustrate with a map the location of your property, accurate to within one-mile, using an easily recognizable coordinate system, to comply with Item 1304(b)(1)(i) of Regulation S-K. Please expand your disclosures to provide the required description and map.

Response 2: In response to the Staff’s comment, we will include a map with proper engineering detail showing the location of our property, as set forth in Annex A attached hereto.

3.

We note that you do not disclose the basket or weighted average price for your composite measure of Total Heavy Minerals (THM), used in determining your resource estimates; the associated metallurgical recoveries; or the operational costs and other parameters involved in establishing the economic cutoff grade.

Please modify your filing to include such details along with a description of the methodology and calculation used to determine your cutoff grade estimate to comply with Item 1302(d)(2) of Regulation S-K. This information should accompany your disclosures of resource estimates either in footnotes to the tabulations or in adjacent disclosures.

Response 3: In response to the Staff’s comment, we will revise the disclosure as set forth as underlined texts in Annex A attached hereto. The Company respectfully advises the Staff that, based on discussions with the Qualified Persons, the basket price of THM is not typically used in the heavy mineral sands industry; instead, the individual heavy mineral prices are used.

    Response No. 2

    Figure 2: Titan Project location of properties containing mineral resources (the coordinate system and datum used for modeling is UTMZ16N, NAD83)

    Response No. 3

    We have reported mineral resources, prepared in accordance with Subpart 1300 requirements of the SEC as part of our exploration and evaluation activities. On July 1, 2022, we filed a technical report summary for our
      Titan Project, dated June 30, 2022, which report is an exhibit to this Annual Report on Form 20-F. As of June 30, 2022, we have reported 431 million metric tons of mineral resources at a grade of 2.2% total heavy minerals (“THM”), containing 9.5
      million metric tons of THM at a 0.4% cut-off. Slimes (“SL”) and oversize material accounts for approximately 20% and 2.5% of the THM fraction respectively. Mineralization occurs as a single, large, and coherent near-surface deposit. In addition,
      preliminary analysis of valuable heavy minerals (“VHM”) (which form a proportion of the THM) indicates a valuable mineral assemblage consisting of zircon, rutile, ilmenite, rare earth elements (“REE”), and staurolite.

    The estimated economic cut-off grade of 0.4% THM utilized for resource reporting purposes has been calculated using on a revenue cost break even calculation and is based on the following assumptions:

          •

            a rutile price of $1,030/t, an ilmenite price of $200/t, a rare earth concentrate price of $4,821/t, and a zircon price of $1,405/t. These prices are based on the historical 2017 to 2021 annual average prices and are considered
                conservative given spot pricing is higher than the assumed prices;

          •

            recovery factors of 82.6% for ilmenite, 60.9% for rutile, 77.1% for rare earth concentrate and 90.8% for zircon;

          •

            operating cost estimates of $3.00/t ROM mining, $3.00/t ROM processing, $0.40/t ROM transport and $0.90/t ROM general and administrative costs; and

          •

            a royalty of 5% is included in the cut-off grade.

    Response No. 5

            11.8

              Cut-off Grade

      A nominal bottom cut of 0.4% THM is offered, based on preliminary assessment of resource value and anticipated operational cost evaluated through preliminary engineering work.

      The estimated economic cut-off grade of 0.4% THM utilized for resource reporting purposes has been calculated using a revenue cost break even calculation and is based on the following assumptions:

            •

              a rutile price of $1,030/t, an ilmenite price of $200/t, a rare earth concentrate price of $4,821/t, and a zircon price of $1,405/t. These prices are based on the historical
                  2017 to 2021 annual average prices and are considered conservative given spot pricing is higher than the assumed prices;

            •

              recovery factors of 82.6% for ilmenite, 60.9% for rutile, 77.1% for rare earth concentrate and 90.8% for zircon;

            •

              operating cost estimates of $3.00/t ROM mining, $3.00/t ROM processing, $0.40/t ROM transport and $0.90/t ROM general and administrative costs; and

            •

              a royalty of 5% is included in the cut-off grade.

      SEC Regulation S-K 1300 requires that all reports of Mineral Resources must have reasonable prospects for eventual economic extraction regardless of the classification of the resource.

      As detailed in the Scoping StudyInitial Assessment, Mineral Resources are amenable to exploitation, incorporating a multi-decade mine life
        and the application of conventional mining and processing technology. IperionX has used TZMI as the basis for pricing of ilmenite, rutile and premium zircon products, and Adamas Intelligence for monazite concentrate. Prices are detailed in
          Table 21, with recovery factors of 82.6% for ilmenite, 60.9% for rutile, 77.1% for monazite concentrates and 90.8% for zircon products.

      The QP has used this information as the basis for determining reasonable prospects for eventual economic extraction.

    Response No. 6

            13.3

              Production Target and Mine Schedule

      Pit optimizations were completed in order to produce a production schedule on an annual basis. This resulted in a total Production Targets of 243 Mt @ 3.0% THM In-Situ with a mine life of 25 years.
        The mining schedule delivers an outcome with the first 14 years mining 100% of indicated  mineralized resource only, and the remaining years mining the inferred mineralized resource, resulting in a total mine life of 25 years. The schedule is based
        on 57% of the total mine ROM material being in an Indicated category. Currently we have no plans to mine and process the remaining mineral resources located outside of this optimized pit; however our plans may
          change as the market evolves.

      The mine schedule is planned to provide a continuous rougher head feed rate of 1,000 tons per hour. The cut-off grade is defined at 1.00% HMTHM
        based on preliminary economic assessment.

      The estimated economic cut-off grade of 1.0% THM utilized for the purposed of determining the optimized pit in the Initial Assessment is based on the following
          assumptions:

            •

              TZMI forecast pricing for ilmenite, rutile and premium zircon products, and Adamas Intelligence forecast pricing for rare earth concentrate as set out in Table 16;

            •

              recovery factors of 81.0% for ilmenite, 72.3% for rutile, 88.2% for rare earth concentrate and 83.3% for zircon;

            •

              operating cost estimates of $1.94/t ROM mining, $3.60/t ROM processing, $0.53/t ROM transport and $1.56/t ROM capital expenditures; and

            •

              a royalty of
