Golden Star Resources
About the organisation
Wassa is located in south-western Ghana. Golden Star commenced production from the surface operation at Wassa in 2005 and commercial production was achieved at Wassa Underground on January 1, 2017. In early 2018 Wassa transitioned into an underground-focused operation. Thanks to the scale of the historical open pit mining operation the processing plant has significant excess capacity and is currently only running at 70-80% (based on 2020 actuals) utilization. Development of the large inferred mineral resource which comprises the southern Extension zone, was the subject of a Preliminary Economic Assessment which was included in the March 2021 Technical Report. Given the scale of the resource at Wassa, the Company is exploring the potential to increase the mining rate in order to fill the mill.
What the listing means
Golden Star Resources appeared on the cmdorganization leak site on 11 July 2026. Groups publish a victim once negotiations stall or as pressure during them, so a listing usually means data was already exfiltrated. This group has published 12 claims in the last 30 days and remains active.
Recommended actions
- Treat any unsolicited message referencing Golden Star Resources as suspicious — leaked data gets weaponised for phishing within days.
- If you hold an account on www.gsr.com, change that password now, update it anywhere you reused it, and enable two-factor authentication.
- Other Energy organisations should review this group's known TTPs and validate detection coverage against them.
- Watch for follow-on extortion: stolen data is often re-leaked or resold after the initial listing.
- A leak-site listing is a claim made by the attacker, not a confirmed breach — check the organisation's own disclosures before acting on it.
