A2Gold Reports Record 141.10 g/t Gold Intercept at Eastside's Castle Target

Tonopah, Nevada – September 21, 2026 -- A2Gold Corp. (TSXV: AUAU) (OTCQX: AUXXF) (FRA: RR7) reported the highest-grade gold assay to date at its Eastside Gold-Silver Project, with drill hole CAC-007 returning 141.10 g/t gold over 0.9 metres roughly 53 metres below surface.

Drill hole CAC-007 delivers 141.10 g/t gold, the strongest result yet at Eastside

The intercept, recorded at 75.9 metres downhole within the existing Castle mineral resource, is tied to an interpreted northeast-striking structural zone where Tertiary volcanic rocks meet Paleozoic sedimentary basement. The result sits along the same structural trend as previously reported high-grade surface samples at Black Rock, which returned 10.50 g/t Au over 0.26 metres and 5.63 g/t Au over 0.28 metres. A2Gold flagged the roughly 400-metre corridor between Black Rock and CAC-007 as incompletely tested and a priority for follow-up drilling.

A2Gold Drilling Expands McIntosh Gold Zone in Nevada

Tonopah, Nev. – September 19, 2026 -- A2Gold Corp. reported new reverse circulation drilling results at its McIntosh Target within the Eastside Gold-Silver Project, identifying a previously untested gold zone 370 metres southwest of the existing resource and extending known mineralization 86 metres to the southeast.

New drill hole intersects gold mineralization tied to untested magnetic anomaly

Hole ES-347 returned 0.23 g/t gold over 65.5 metres starting at 253.0 metres downhole, marking discovery of a new mineralized zone associated with a roughly 1.5-kilometre-long magnetic low anomaly that had not previously been drill-tested. The company said gold grades occur primarily along the margins of magnetic low anomalies, a pattern consistent with the geophysical signature of the existing McIntosh resource.
