Compass Reports Strong Gold Recoveries from Recent Metallurgical Testing at Massala

• Compass Gold Corp. announced the completion of Phase 1 resource definition drilling at its Massala prospect in Mali, totaling 42 holes and 1,457.3 meters.
• Independent metallurgical testing by Blue Coast Research demonstrated robust gravity recoverable gold (EGRG) between 51.1% and 61.0%, with a final bottle roll leaching recovery of 95.3%.
• Initial assays revealed high-grade intervals and visible gold exceeding 100 g/t Au, though 39 additional hole assays remain pending.
• The company appointed Colin Galinski as Vice President, Corporate Affairs to support the Small Mine strategy execution.
• Drilling was conducted at 55° dips and 270° azimuths within a 340m strike area, targeting near-surface mineralization for resource estimation.
• QAQC protocols were maintained with certified reference materials, blanks, and duplicates, with assays processed by SGS in Burkina Faso due to temporary lab pauses in Bamako.

• The metallurgical results significantly de-risk the processing flowsheet, confirming that Massala gold is moderate-to-fine-grained, free-milling, and amenable to conventional, low-cost gravity separation and cyanide leaching.
• This is an expected operational milestone following the April 2026 announcement of ongoing metallurgical testing. The market has not reacted strongly, with the stock consolidating in a tight range, indicating the results are priced in as routine progress.
• The completion of Phase 1 drilling advances the path to an initial resource estimate, but the pending assays for 39 holes and the lack of a formal NI 43-101 feasibility study mean technical and economic uncertainties remain.
• The appointment of a VP Corporate Affairs is a standard governance step and does not alter the project's technical or financial trajectory.

• Compass Gold is a pre-revenue junior explorer advancing the Massala small mine project on the 911 sq km Sikasso Property in southern Mali.
• The flagship project targets near-surface, open-pit gold mineralization along the 15 km Tarabala Trend.
• Management's strategy is to bypass a formal NI 43-101 feasibility study, relying instead on bulk sampling, metallurgical testing, and management's historical expertise to accelerate cash flow generation.
• The project aims for a low-capital, low-operating-cost model with a 4-year initial mine life and a processing limit of 50 tonnes per hour.
• No formal reserves or resources have been declared yet, as the company is still in the resource definition phase.
