Sanu Gold hits 90%+ gold recovery in initial metallurgical tests at Daina, Diguifara

Vancouver, British Columbia--(Newsfile Corp. - September 22, 2026) - Sanu Gold Corp. (CSE: SANU) (OTCQB: SNGCF) ("Sanu Gold" or the "Company") is pleased to announce positive metallurgical test results for samples collected from the Company's Daina and Diguifara gold exploration properties ("Daina" and "Diguifara") in Guinea, West Africa.

Highlights

Initial metallurgical testwork was undertaken on 136 selected drill samples from the Daina and Diguifara properties, encompassing a broad range of gold grades.

The testwork returned recoveries of:

91% average gold recovery from 91 samples at Diguifara; and

94% average gold recovery from 45 samples at Daina.

At Daina, recoveries ranged from 93.2% to 94.6% across the three calculated head-grade ranges tested. At Diguifara, the corresponding averages ranged from 88.2% to 94.6%.

Recoveries across the oxide, transition and fresh-rock categories ranged from 93.8% to 94.2% at Daina and 90.1% to 92.3% at Diguifara.

The results are broadly comparable in magnitude to the Company's previous initial cyanide leach results at Bantabaye, which returned average gold recoveries of 92% to 93%.

These preliminary results indicate a high proportion of cyanide-soluble gold in the selected samples and support further metallurgical testwork.

These preliminary screening results support more detailed metallurgical testwork using representative composite samples.

Martin Pawlitschek, President and CEO of Sanu Gold, commented : "These initial cyanide leach results are encouraging, with average gold recoveries of 91% at Diguifara and 94% at Daina. High calculated recoveries were observed across the weathering categories and calculated head-grade ranges tested. At Daina, recoveries ranged from 93% to 95% across the tested grade bands. At Diguifara, recoveries ranged from 88% in samp
