PRODUCTION UPDATE WITH GUIDANCE MAINTAINED

Regis Resources Limited ASX:RRL ( Regis or the Company ) presents preliminary production commentary from its operations at Duketon (100%) and Tropicana (70% AngloGold Ashanti Limited and manager / Regis 30%). Details will be available in the March 2024 quarterly report scheduled for release in April.

Recent rain events impacting operations.

• In March a substantial and protracted regional rain event, with more than 50% of average annual rainfall month to date, has impacted operations.

• Duketon received ~110 mm of rain so far this month, with the town of Laverton also reporting ~110 mm over the same period. The substantial rainfall event has resulted in the temporary closure of Laverton Shire roads which provide land access to Duketon. Despite these difficulties Duketon has to date continued to perform with limited production loss.

• Tropicana has also been impacted by heavy rains this month including 310mm of rain over a three-day period. While the team on site has done an excellent job managing any potential safety issues, the deluge did result in the suspension of mining operations and a disruption to power supply. The process plant is now treating stockpiles and underground feed while ore mining from the open pits remains restricted. The rains have closed the supply road between Kalgoorlie and Tropicana and processing may have to be suspended if consumable stocks on site are exhausted.

• As a result of these impacts the company’s Group March quarterly gold production is anticipated to be in the range 90-95,000oz.

• With these production difficulties, Tropicana will be challenging the lower end of its annual guidance range. However, the continued strong performance at Duketon means the group FY24 production guidance remains unchanged. Ongoing impacts continue to be assessed.

FY24 GUIDANCE MAINTAINED

Group production and all-in sustaining cost guidance for FY24 remains unchanged:

• Gold production 415,000 - 455,000 oz

• All in sustaining costs $1,995 - $2,315/oz (incl. ~$200/oz non-cash stockpile inventory adjustment)

• • Growth capital $85M - $95M*

• Exploration $48M - $55M

• • McPhillamys $22M - $25M

• Final assessment of the two potential new underground capital project areas at Duketon, Rosemont Stage 3 and Garden Well Main, will be completed in H2 FY24.
