Perseus delivers strong operational performance with cash & bullion increased to US$1 billion

PERTH, Western Australia/ July 30, 2026/ Perseus Mining Limited ("Perseus” or the "Company”) (TSX & ASX: PRU) reports on its activities for the three months’ period ended on June 30, 2026 (the "Quarter”). Below is a summary of the release. The full report is available at www.perseusmining.com, www.sedarplus.ca and www.asx.com.au.

Production and AISC guidance for June 2027 Financial Year (FY27) of 420,000 - 480,000 ounces at US$1,835 - 2,070 per ounce AISC.

Key operating indicators and highlights for the June 2026 quarter (Q4 FY26) include:

"This was a quarter of significant milestones for Perseus - first stoping ore from CMA Underground, a first for both Perseus and Côte d'Ivoire, an outstanding safety achievement at Nyanzaga, and cash and bullion passing US$1 billion for the first time. That balance sheet strength gives us the flexibility to keep investing in our growth pipeline while continuing returns to shareholders as reflected in the Board’s decision to upsize our buyback to $150m this quarter. I want to thank our employees and contractors across all our operations and projects for their dedication and hard work over the past year - the milestones we've delivered are a direct reflection of their commitment.

Looking ahead, FY27 will be a transformational year for Perseusas we bring two major growth projects - CMA Underground and Nyanzaga - through to commercial production alongside our existing operations”.
