There were 119,683 ounces of gold recovered at the company's three operations, which was up 15% on the December 2019 quarter.
The production from Syama in Mali was particularly encouraging with 57,531 ounces of gold poured, up 23% on the previous quarter.
Shares have been almost 7% higher in early ASX trading to A84.5 cents, up from A62 cents on March 16.
Managing director and chief executive officer John Welborn commended the Resolute team on the company’s response to the coronavirus COVID-19 pandemic and the focus on maintaining and improving operational performance.
He said: “Across our business we remain Resolute.
“Our collective response to COVID-19 and our performance in the March quarter have allowed us to maintain our previous production and cost guidance for 2020 for Syama and Mako.
“At the group level, we have updated our 2020 guidance to 430,000 ounces of gold production at an All-In Sustaining Cost of US$980/ounce.”
The new guidance update removes future production from Ravenswood following the sale of the asset.
Group level cost guidance of US$980/ounce has been maintained to reflect production costs incurred at Ravenswood and the uncertainty related to potential increases in corporate costs associated with managing the impacts of COVID-19.
Strong performance at Syama
There was a strong underground mining performance at Syama, with mined and hauled ore of 520,000 tonnes at 2.6 g/t gold, representing an increase of 33% on the December quarter.

Recoveries are expected to average 80% for the June 2020 quarter with gradual progress enabling the company to deliver target sulphide circuit recoveries of 85% during the second half of 2020.
Available underground sulphide ore stockpiled at Syama has increased to 517,000 tonnes at an average grade of 2.5 g/t gold.
Resolute guidance for Syama has been maintained at 260,000 ounces at an ASIC of US$960/ounce.

The sale was completed during the March 2020 quarter.
Resolute continues to assess developments and update the company’s response appropriately while placing the highest priority on the safety and well-being of its employees, contractors and stakeholders.
Further escalation of COVID-19, and the implementation of further government-regulated restrictions or extended periods of supply chain disruption, has the potential to negatively impact gold production, earnings, cash flow and the company’s balance sheet.
