Perth, Western Australia/December 23, 2025 / Perseus Mining Limited (ASX/TSX: PRU) today announces it has successfully executed an amendment, including an upsize and extension, of its existing syndicated loan facility. Prior to the amendment and extension, the syndicated loan maturity was $300 million out to March 2026. The amended facility has been increased to US$400 million plus a US$100 million Accordion Option. It has a three year term plus an option to extend for two years (1+1)³. Very competitive pricing was achieved on the new extended facility, being reverse-flexed in syndication due to strong demand and resulting in a total margin reduction of 125 basis points from the existing facility. Amendments were made to provide Perseus with more flexibility across a range of terms, including Financial Covenants, reflecting the continued enhancement of Perseus' credit profile.

The amended facility is available for general corporate purposes, subject to the satisfaction of certain customary conditions precedent, and combined with Perseus's Sept 30, 2025 net cash position of US$837 million, it provides the company with more than US$1,237 million of available liquidity.

The new banking consortium consists of eight international banks comprising the six existing banks Macquarie Bank Limited from Australia; Nedbank Limited (acting through its Nedbank Corporate and Investment Banking Division); Absa Bank (Mauritius) Limited; Citi; FirstRand Bank Limited (acting through its Rand Merchant Bank Division); and Standard Bank of South Africa Limited (Isle of Man Branch) and two new international banks, JP Morgan (Australia) and Standard Chartered (Australia).

Perseus's Chief Financial Officer Lee-Anne de Bruin said:“Perseus has received very strong support from of a consortium of high-quality international lenders including two additional international banks joining the syndication. The process was more than 100% oversubscribed which is regarded as a major endorsement of the underlying quality of our assets and future cash flows.

With cash and undrawn debt capacity exceeding US$1.2 billion, Perseus is fully funded to deliver on our 5 Year Outlook and pursue future growth opportunities whilst maintaining our commitment to return funds to shareholders via ongoing dividends and share buy backs”.
