Resouro Gold Releases Positive Metallurgical Test Work Results and Receives

Trial Mining License for Its Novo Mundo Project in Brazil

Vancouver, B.C. – October 4, 2022 - Resouro Gold Inc. (TSXV: RAU) (“Resouro” or the “Company”) is

pleased to announce that the Brazilian Mining Agency has granted a Guia de Utilização (“Trial Mining

License”), inclusive of environmental and installation license, on the Company’s wholly-owned Novo

Mundo Project located in the prolific Mato Grosso area in Brazil . As part of the application, the

Company submitted a 96.58 kg composite sample of previously stockpiled material and base-of-pit

material for preliminary metallurgical processing studies (the “Metallurgical Test Work”). The results

of the studies all exceed 90% gold recoveries using conventional processing flowsheets.

The receipt of the license permits Resouro to install all necessary infrastructure and equipment

required for trial mining and commence trial mining at Novo Mundo. Most gold operations in Brazil

start production with a Trial Mining License, which is the normal path to the grant of a full mining

license.

Trial mining at Novo Mundo will go in parallel with further exploration and drilling efforts to continue

uncovering the Project’s vast blue-sky potential. Phase 1 drill program is now complete, with assays

from the first two holes reported and assays from nine more holes pending.

Highlights of the Metallurgical Test Work include:

• Sulphide zone test work head grade of 16.45 g/t gold

• 98.4% overall gold recovery from gravimetric concentration followed by rougher flotation of

the 106 μm size fraction

• 93.70% overall gold recovery from gravimetric concentration followed by CIL leaching with 5.7

kg/t of cyanide consumption

• 27.89-30.21% gold recoveries from gravimetric concentration

• Comparatively soft rock with a Bond Work Index of 14.3 kWh/t

The Metallurgical Test Work was completed by the TestWorks NL, a respected Brazilian metallurgical

engineering group.

Chris Eager, CEO of Resouro, comments: “The approval of the Trial Mining License and highly

encouraging preliminary metallurgical test results reaffirm Resouro’s commitment to moving Novo

Mundo towards development. Mining regulations in Brazil enable projects to be advanced towards

production rapidly, and the grant of Resouro’s Trial Mining License demonstrates that this path can

be navigated successfully. The preliminary test work showed that conventional processing flowsheets

using off-the-shelf processing equipment can achieve over 90% gold recovery, which is very

encouraging for us.”

“With the license in hand and a good grip on the processing methods the minerali zation at Novo

Mundo requires, the Company is well placed to advance discussions with local equipment

manufacturers for initial project development,” he adds.

The Phase 1 drill program was designed to delineate the subsurface mineralization that exists in the

unweathered zone, which the local miner’s rudimentary recovery methods had previously been

ineffective at extracting the gold from. The results of the test work demonstrate that the high-grade

gold hosted in this unweathered zone can be liberated with conventional leaching and flotation flow

sheets, obtaining total recoveries in excess of 90%.

Summary of the completed Metallurgical Test Work as well as the in-depth report can be found on

the Company’s website: Metallurgical Test Work Summary.
