4. Adjustments to Unaudited Pro Forma Condensed Consolidated Combined
Financial Information, page 87

 9. We refer you to footnote 4.F and the adjustment for $11,997,000
of transaction costs expensed as part of the Business Combination. Please tell us how this amount corresponds with the adjustment for
$12,320,000 in estimated non-accrued transaction expenses disclosed at page xxii, the estimated transaction fees and expenses of $18,460,000
disclosed at page 19, and the $16,580,000 adjustment in footnote 4.AA.

Response to Comment No. 9

The Company acknowledges the Staff’s
comment and respectfully advises the Staff that it has revised its disclosure accordingly. The estimated non-accrued transaction expenses
of $12,320,000 have been adjusted on page xxii to $11,997,000 to reconcile with the adjustment in footnote 4.F. The estimated transaction
fees and expenses of $18,460,000 have been revised on pages 19-21 and 133-135 to $18,751,687, which includes $11,997,000 of transaction
costs settled in the adjustment in footnote 4.F and $6,754,687 of accrued expenses, which is included within the adjustment in footnote
4.D (settlement of HCVI accrued transaction costs).

The description of the adjustment in footnote
4.AA inappropriately cross-referenced the adjustment in footnote 4.F and the cross-reference has been removed from page 92. The adjustment
in footnote 4.F gives effect to the Closing as if it occurred on June 30, 2024, and was computed utilizing historical financial information
as of June 30, 2024, while the adjustment in footnote 4.AA gives effect to the Closing as if it occurred on January 1, 2023, and was computed
utilizing historical financial information for the year ended December 31, 2023.

 10. Please tell us the basis for and explain the difference between
the fair value of the Sponsor earnout of $670,695 in adjustment 4.G.3 and the fair value of the Sponsor earnout of $17,020,000 in adjustment
4.J.

Response to Comment No. 10

The Company acknowledges the Staff’s
comment and respectfully advises the Staff that it has revised its disclosure for adjustment 4.G.3 regarding the Sponsor Earnout on page
90.

The fair value of the Sponsor Earnout was
determined utilizing a Monte-Carlo simulation which considered the term, volatility, risk-free rates, and vesting conditions which are
described on pages 81-82.

As the Sponsor Earnout represents consideration
issued to acquire the SPAC, the total $17,020,000 fair value of the Sponsor Earnout is allocated between IAS 32/IFRS 9 (representing the
liability-classified portion issued to acquire the net assets of the SPAC) and IFRS 2 (representing the equity-classified portion issued
to acquire the listing status of the SPAC). $670,695 represented the liability-classified component of the $17,020,000 total fair value;
however, this amount has been adjusted as further described below.

The allocation ratio used to allocate the
total fair value of the Sponsor Earnout into the liability and equity components has been adjusted, resulting in changes to the adjustments
in 4.G.3 under each redemption scenario.

 11. We refer you to footnote 4.I.2. Please tell us what 15 million Company Earnout represents and how this relates to the Company Earnout
Shares of 30 million presented in the table at page 16.

Response to Comment No. 11

The Company acknowledges the Staff’s
comment and respectfully advises the Staff that it has revised its disclosure on page 91 to renumber footnote 4.I.2 as footnote 4.O and
to read as follows: “Reflects the recognition of the Company Earnout, which is classified as a liability at fair value in accordance
with the requirements of IAS 32.” The original text within footnote 4.I.2 incorrectly referenced 15 million shares. The fair value
of the Company Earnout posted within adjustment 4.O was determined based on 30 million of aggregate issuable shares.

 12. We refer you to footnote 4.J. Please tell us how you determined the net assets of HCVI under each of the three redemption scenarios.

Response to Comment No. 12

The Company acknowledges the Staff’s
comment and respectfully advises the Staff that its response did not result in a revision in disclosure. The net assets of HCVI per adjustment
4.J were calculated as follows: (a) HCVI’s historical net assets as of 6/30/24, less (b) estimated HCVI transaction costs still
to be incurred as of 6/30/24, less (c) HCVI’s 9/30/24 redemption payments, less (d) the applicable cash impact under the no redemption,
50% redemption, and max redemption scenarios.

 13. We refer you to note (1) of footnote 5. Please tell us how you considered the additional dilution sources that are summarized in the
table at page xxiv with the disclosure in this note stating that the conversion of Pubco Warrants is the only share-based instrument which
may result in dilution after the Closing Date.

Response to Comment No. 13

The Company acknowledges the Staff’s
comment and respectfully advises the Staff that it has revised its disclosure in note (1) of footnote 5 on page 93 to reflect additional
sources of potential dilution, including the issuance of Company Earnout shares and the issuance of PubCo Ordinary Shares under the Equity
Incentive Plan.

The Background of the Business Combination,

 14. We note your revised disclosure in response to prior comment 27 that the $500 million valuation was derived from a peer comparison
analysis, consisting of other African gold companies at similar stages of development, based on an EV/Resource (total ounces of gold)
multiple of approximately $71 – $72 applied to the estimated resources of approximately 5.2 million ounces of gold provided by Greenstone
management, and additional credit for Greenstone’s past producing assets with existing infrastructure and capital spend in the ground,
historical production, cash flows from ongoing production and existing mining permits. Please describe in greater detail this peer comparison
analysis provided by Greenstone management and utilized by HCVI management to derive the valuation. For example, disclose the names of
the companies selected for this analysis and corresponding EV/Resource multiples. Also include more detailed disclosure and quantify to
the extent possible the additional credit for Greenstone’s past producing assets with existing infrastructure and capital spend
in the ground, historical production, cash flows from ongoing production and existing mining permits.
