Last week, five members of our team represented OceanaGold at the #AusIMM International Mine Geology Conference in Brisbane, Australia.

👉Our Head of Exploration, Lauren Elliott delivered a keynote on the value of geological intuition built through experience: The Mine Geologist’s Edge in Mine Exploration.
👉Wesly Randa CP(Geo) challenged assumptions around mine chain reconciliation by asking whether success is truly understood.
👉Matthew Grant examined model to mine reconciliation and infill drilling effectiveness through retrospective moving point of origin analysis, offering a practical insight into improving confidence in geological models.

Great work by the team in sharing experience-driven insight, challenging accepted thinking, and helping to advance industry conversation!

[Perseus Mining @PerseusMining]

Perseus’s long-serving Managing Director and CEO Jeff Quartermaine has advised he will retire from the role, after a 12-year tenure with the company.

His retirement will take effect from 30 September 2025, after which he has agreed to continue to support the Company through a Consultancy Agreement on market terms. Former Newcrest global Chief Operating Officer Craig Jones will replace Jeff, commencing with Perseus on 18 August 2025 before assuming the MD and CEO role on 1 October 2025.

Jeff joined Perseus in 2010 as Chief Financial Officer, before being appointed CEO in 2013. Since assuming this role, he has transformed Perseus from a struggling single-mine, single-country company to a multi-mine, multi-jurisdictional gold producer, developer and explorer that has consistently delivered on its promises and is now one of the leading gold companies operating on the African continent. Perseus now has three operating gold mines, Edikan in Ghana and Yaouré and Sissingué in Côte d’Ivoire, and is building a fourth mine, Nyanzaga, in Tanzania, which is on track to commence gold production in Q1 CY2027.

Our Chairman Rick Menell praised Jeff’s outstanding contribution in leading and shaping Perseus into the company it is today, saying: “On behalf of the Board, I would like to express my most sincere gratitude to Jeff for his leadership and guidance over the years. Jeff has transformed Perseus and has been pivotal in turning it into one of the most profitable gold producers in the world. He has built extremely solid foundations for the Company to keep growing and we cannot thank him enough for such a positive legacy.”

Jeff said: “It has been an honour and a privilege to have had the opportunity to serve at the helm of Perseus Mining over the past 12 years. Not only has the Company been transformed into a credible ASX 100 organisation, but during this time we have generated significant benefits for all of our stakeholders, including many in our host communities in Africa whose lives have been significantly improved through Perseus’s endeavours.

"I am deeply indebted to all our staff, both past and present, who along with their families have given their friendship, hard work, and commitment in helping transform Perseus. Along the way we have faced a myriad of challenges including events such as the global COVID pandemic, but we have emerged stronger than ever, and the company is now well positioned to continue our success into the future.”

Today we announced further encouraging drill results at our Nyanzaga Gold Project in Tanzania: https://t.co/PSLanxJGTr

Perseus Mining MD & CEO Jeff Quartermaine said the results "reinforce our confidence in our ability to expand Nyanzaga’s Mineral Resources and Reserves and as a result, potentially extend the life of the mine beyond the currently predicted Phase 1 of 11 years".

Further drilling programs are scheduled to be completed by December 2025 and results will be incorporated into an updated Nyanzaga Ore Reserve statement expected Q1 CY26.
