The Board of RTG Mining Inc. (“RTG”, or the “Company”) (TSX Code: RTG, ASX Code:

RTG) is pleased to provide an update on the financing process for the development of

the high-grade Copper and Gold Mabilo Project (“the Project”) in the Philippines . RTG

holds a 40% interest in Mt. Labo Exploration and Development Corporation (“ MLEDC”)

which owns 100% of the Mabilo Project, together with a 2% Net Smelter Royalty.

RTG confirms that following a short due diligence period, MLEDC has received multiple

debt finance and offtake offers to fund 100% of the planned capital expenditure for the

development of Stage 1 of the Project, on attractive terms.

Operational start-up of Stage 1 at Mabilo is a significant milestone for RTG investors,

highlighted by a high-grade Direct Shipping Operation (“DSO”) that will mine, amongst

other products, approximately 100,000t of supergene chalcocite material which runs

in the order of 21% reserve grade copper1.

With all initial finance offers now received, MLEDC will analyse the various term sheets

and seek to optimise the preferred offers, with a view to selecting a final party and moving

to signing binding documentation in the near-term.

Management Commentary:

Commenting on this key development, RTG’s CEO Justine Magee said: “This is a

very important step in the development of the high-grade Mabilo Copper-Gold Project and

places the project in a prime position to capitalise on consensus views of a strong and

improving forecast for copper prices. The offers for 100% finance for Stage 1 CAPEX

also demonstrate the strong economics and cashflow underpinning Mabilo’s

development, with few projects capable of securing such attractive financing terms. RTG

will now focus on securing the most appropriate, non -dilutive funding option to advance

this asset forward.”
