Two S&P/ASX 200 Index (ASX: XJO) gold stocks are grabbing plenty of investor attention today after releasing their latest quarterly results.
Ramelius Resources Ltd (ASX: RMS) shares are down 8.3% at $3.21 apiece after the miner reported on its September quarter performance.
And Perseus Mining Ltd (ASX: PRU) shares are up 0.6% at $4.76 each following the company's own release.
For some context, the ASX 200 is up 0.4% at this same time.
Here's what's happening.
ASX 200 gold stock tumbles on production slide
Ramelius Resources shares are falling after the miner reported gold production of 55,013 ounces for the three months to 30 September, down 25.1% quarter on quarter.
Ramelius produced the gold at an all-in sustaining cost (AISC) of $1,836 per ounce.
Gold sales came in at 54,734 ounces, with the ASX 200 gold stock achieving an average price of $4,528 per ounce for revenue of $248 million.
Of potential concern, management noted that grades at the company's Cue project have reverted back closer to Ore Reserve estimates following several quarters of outperformance.
They noted:
Given this and increased production from Penny West (as opposed to Penny North), Mt Magnet production grades will be slightly lower going forward until such time that material quantities of Dalgaranga (Never Never) ore are available in late FY26 .
As at 30 September, the ASX 200 gold stock had cash and gold holdings of $827.7 million, up 2.2% from the June quarter.
Management said they will provide FY 2026 production, AISC, and capital guidance as part of Ramelius' five-year outlook on 28 October.
With today's intraday fall factored in, Ramelius Resources shares remain up 52.1% in 2025.
Which brings us to…
Perseus Mining shares in the spotlight

Gold sales from the miner's three operations totalled 101,589 ounces. That's down 29,653 ounces quarter on quarter, impacted by lower production. Though management noted this is in line with Perseus' FY 2026 guidance and the timing of shipments.

The company's share buyback program of up to $100 million over 12 months was also renewed.
