Exhibit 99.1 Gold Fields Limited Reg. No. 1968/004880/06) Incorporated in the Republic of South Africa) JSE, NYSE, DIFX Share Code: GFI ISIN Code:ZAE000018123 (“Gold Fields” or the “Company”) GOLD FIELDS PROVIDES CLARIFICATION ON MEDIA REPORTS RELATED TO THE TARKWA MINING LEASE RENEWAL PROCESS Gold Fields notes recent media reports referencing the process currently underway with the Government of Ghana with respect to the renewal of the Tarkwa mining leases. The Company confirms, as previously announced, that Gold Fields Ghana Limited (GFGL), a 90% held subsidiary of Gold Fields and the holding company for the Tarkwa mine submitted an early application for the five Tarkwa mining leases that are due for renewal in April 2027, consistent with the agreement reached with the Government of Ghana in April 2025. Subsequent to this submission in November 2025, Gold Fields has held several engagements with the Government of Ghana, with the discussions now focusing on the terms of the mining lease renewals. The outcome, timing and terms of the lease renewals remain the subject of these ongoing engagements with the Government of Ghana. Gold Fields remains committed to both the Tarkwa mine and its continued operation in Ghana. Given the Company’s experience of delivering safe and responsible mining operations, employment creation and partnerships in Ghana, together with its global technical expertise and investment capacity, Gold Fields believes it is well positioned, subject to the outcome of the renewal process, to continue operating and growing the Tarkwa mine beyond the current life of mine, creating shared value for both Ghana and Gold Fields. The Company will provide further updates on the Tarkwa lease renewals should there be any material developments.
