MARI Marimaca Copper Corp

Marimaca Copper Corp. (“Marimaca” or the “Company”) (TSX: MARI) is pleased to announce that the Company has lodged a prospectus (the “Prospectus”) with the Australian Securities and Investments Commission (“ASIC”) in relation to its proposed listing on the Australian Securities Exchange (“ASX”).

Under the Prospectus, the Company will offer one hundred (100) common shares in the Company (the “Shares”) in the form of CHESS Depository Interests (“CDIs”) at an issue price of A$6.00 per CDI to raise gross proceeds of A$600 (the “Offer”). Each CDI will represent one underlying Share. The Prospectus will also enable the Company to comply with the admission requirements of Chapters 1 and 2 of the ASX Listing Rules, as part of its application for admission to the official list of ASX. The Offer is expected to open on or around Tuesday, 4 February 2025, and is expected to close on Tuesday, 11 February 2025, with the expected commencement of trading of CDIs on the ASX to be on or around Thursday, 13 March 2025.

The net proceeds raised pursuant to the dual listing on the ASX will be used for Marimaca’s general working capital purposes, including to partially cover the costs of the Offer.

The Company has absolute discretion regarding the allocation of CDIs to applicants under the Offer and may reject an application or allocate a lesser number of CDIs than applied for by the applicant. The Company also reserves the right to aggregate any applications that it believes may be multiple applications for the same person.

A copy of the Prospectus will be available on SEDAR+ at www.sedarplus.ca under the Company’s profile. However, the Offer is only open to investors who are invited by the Company to participate and with a registered address in Australia. Investors outside Australia (including Canadian residents) may not participate.

The dual listing is subject to regulatory approval and market conditions.

In accordance with section 734(6) of the Australian Corporations Act 2001 (Cth), the Company advises in respect of the Offer of CDIs under the Prospectus:

• the issuer of the CDIs is Marimaca Copper Corp. ARBN 683 017 094; 
• the Prospectus is available online for Australian residents only at www.marimaca.com or by contacting the Company by email at marimaca@tavistock.co.uk;

Hayden Locke, President & CEO, commented:

“As we move closer to a construction decision for the Marimaca Oxide Deposit (the “MOD”), and continue our aggressive exploration plans, a broader pool of capital will become increasingly important to our Company. We believe a dual listing on the ASX complements and enhances the strong support we have received from our TSX shareholder base.”

“Our development strategy continues to gain momentum. We have submitted our permit application for the MOD and expect to have more clarity on anticipated timelines towards the end of February 2025, following reception of the first pronouncement by the authorities over our submission. The Definitive Feasibility Study is progressing, and we expect it to be finalized in Q2 of 2025 with its release to the market thereafter. We also continue to add high quality personnel to our expanding Owner’s Team as we continue the transition from explorer to developer in preparation for a construction decision.”

“In parallel, we will be following up on the exciting results of our recent step out exploration program at Pampa Medina Norte. We believe it offers considerable potential catalysts, particularly around growth in our mineral inventory, for our shareholders over the short to medium term.”
