EcoGraf (ASX:EGR) has announced results from its first exploration campaign at the Hazina prospect, part of its Southern Frontier Gold Project in Tanzania.
The initial reconnaissance program, conducted across 16 sites, focused on stream sediment and rock chip sampling near artisanal workings.
The work targeted alluvial gold in river gravels and aimed to identify potential bedrock mineralisation.
Assays revealed fine, coarse, and heavy mineral concentrates exceeding 100 parts per billion gold, with a peak value of 8,820ppb.
The two highest-grade results coincided with a high-magnetic anomaly at Hazina, providing dual validation of the area's exploration potential.
Four rock chip samples from outcrops returned a maximum of 4,450ppb gold (4.42g/t), highlighting potential for a Proterozoic-scale discovery comparable to Tanzania’s 1 million-ounce Handeni deposit and the 1.1Moz New Luika mine.
Southern Frontier, which includes Hazina, Johari North, Jahari South, Tunu North, and Tuna South targets, lies roughly 15km south of EcoGraf’s flagship Epanko Graphite Project in Ulanga district.
The results align with the company's initial mineralisation model and will inform follow-up studies to advance the project toward drill-ready status.
EcoGraf also announced the appointment of mining executive John Ciganek as general manager, corporate development.
At the time of reporting, EcoGraf's share price was $0.37.
