SUBIACO, AU / ACCESS Newswire / March 31, 2025 / The Board of RTG Mining Inc. ("RTG", the "Company") (TSX Code:RTG)(ASX Code:RTG) is pleased to announce that the Company has received commitments to raise approximately A$19.5 million (circa US$12.3 million) in a placement to institutional and sophisticated investors ("Placement").

As recently reported (see ASX announcement dated 6 March 2025), the Secured Financing Facility with Glencore International AG ("Glencore"), provides for a total of up to US$30 million (in three-tranches), on attractive terms, for the development of Stage 1 of the high-grade copper and gold Mabilo Project in the Philippines. Subsequent to securing binding finance and offtake arrangements with Glencore, the Placement has received strong institutional demand, demonstrating the considerable support for RTG's high-grade copper and gold strategy.

The Placement will result in the issue of approximately 783 million Chess Depository Instruments ("New Securities") to be listed on the ASX at an issue price of A$0.025 per Security ("Issue Price"), representing a 3.8% discount to RTG's last closing price on the ASX of A$0.026.

Net proceeds of the Placement will be used to provide working capital to advance the Mabilo Project towards start-up and operations to unlock the early and strong cashflows of the project, with the first phase being a Direct Shipping Operation. RTG will also be well funded to progress plans for additional exploration at the Mabilo Project to expand the current reserve in the oxide layer, including additional high grade supergene chalcocite copper material and further drilling to then expand the reserves in the primary skarn material for Stage 2.

In addition to this drilling, RTG will commit to a 5,000m drill program at the Chanach Project, including 3,000m into the potential high grade porphyry target identified in the recent 3DIP programs. This will run from late May through to October/November depending on the available field season. Other work plans include continuing the pursuit of new potential business development opportunities, including the Panguna Project in the Autonomous Region of Bougainville and general working capital purposes.

Placement Details:

The Placement consists of 783 million New Securities to be issued at the Issue Price of A$0.025 per Security to raise total funds of circa A$19.5 million. The Placement will be conducted in two tranches. The first tranche of approximately 169,297,750 New Securities is expected to be issued on or around 9 April 2025 using the Company's 15% placement capacity under ASX Listing Rule 7.1 to raise ~A$4.2 million (before costs).

The second tranche of New Securities, being the balance of the Placement (~613.7 million New Securities), will be issued as follows:

• subject to receiving shareholder approval under ASX Listing Rule 10.11, the issue of up to 7 million New Securities to the RTG Directors and up to 241 million New Securities to Equinox Partners LP, which is deemed to be a ‘related party' of the Company by virtue of Non-Executive Director Mr Sean Fieler's position as a controlling member of Equinox Partners GP, the General Partner of Equinox Partners LP; and

• subject to receiving shareholder approval under ASX Listing Rule 7.1, the further issue of a total of up to 365 million New Securities to institutional and sophisticated investors (including existing shareholders of RTG).

Shareholder approval for the issue of the New Securities under the second tranche of the Placement will be sought at a General Meeting of the Company expected to be held in May 2025. Settlement and allotment of New Securities under the second tranche of the Placement are expected to occur shortly after approval is obtained at the General Meeting. Furter details relating to the issue of these New Securities will be set out in a Notice of Meeting to be sent to shareholders in due course.

Foster Stockbroking Pty Ltd ("FSB") acted as lead manager and bookrunner to the Placement ("Lead Manager").

The Placement will be conducted under exemptions from prospectus and registration requirements of securities laws in relevant countries. The Placement is subject to approval of TSX.
